The portable grandfathers that appear are all problematic.

However, even the Dreadnoughts will suffer heavy losses when facing the Warriors and the Insect Royal.

These mechs, with weapons far more powerful than those of the Zerg, superior troop production technology, and unwavering morale, showed Xue the best way to deal with natural disasters: another natural disaster!

Otherwise, relying solely on the killing efficiency of the Dreadnoughts would likely result in an exceptionally long war.

Therefore, are there other natural disasters in the universe?

Demons (Undead)!

Xue Dinglu immediately thought of the Impure World Reincarnation or the Summoning of Heroic Spirits, which involved enslaving the dead, but he quickly dismissed the idea, as he was not yet capable of using such a technique.

However, there is another natural disaster in the universe.

The divine tree has descended!

Furthermore, the Divine Tree can infect other life forms, causing them to be covered in fungal spores and turn into a "plant monster." Actually, according to the name used by the angels in Rachel's world, "Deadpool" sounds better.

Similarly, Deadpool is also part of the Second Catastrophe.

And coincidentally, Xue Law had the materials for the Divine Tree. The essence of the Divine Tree was an ancient prokaryotic organism called "Wild Fungus," which only appeared to be a plant.

Without hesitation, Xue Dinglu jumped out and said, "Gentlemen, are there any insects here? I need a real Shub insect, preferably a juvenile, for my research."

This requirement stunned everyone else at the outpost; they couldn't understand why Xue's Law would make such a request.

However, they wouldn't question it. After Xue Lude set up the isolation barrier, a Dreadnought brought over the charred corpse of the Shub insectoid, saying, "Not completely dead yet, but it should be about half-cooked. It shouldn't affect your research, right?"

"OK!"

Xue Dinglu immediately began to study the cells of the Divine Tree and the Zerg. With the knowledge of his two doctoral degrees from his parallel world self, plus the cheat-like modification by the Cursed Blood, he indeed discovered the problem.

After the cells of the Divine Tree enter the bodies of the Shub insectoids, they are able to devour the insectoids' energy and grow within their bodies!

Just minutes later, the insect stopped struggling, and a branch grew from its corpse, seemingly growing exceptionally well.

It doesn't even require much processing or modification. Xue's Law only needs to consider that after using this thing to wipe out the swarm, the rest is the outbreak of the God Tree Dead Servants catastrophe, just like how Earth in a parallel world still has hundreds of millions of Dead Servants.

Therefore, Xue's Law quickly modified a divine tree cell using the cursed blood, that is, by hiding the bacteriophage in the divine tree cell through a simple membrane, and then hiding it in the source nucleus of the divine tree cell.

Under normal circumstances, the reproduction and growth of the divine tree cells will not trigger the bacteriophages of the source nucleus. However, once the divine tree begins to absorb spiritual energy and reproduces, the membrane will rupture, and the bacteriophages will swarm out to destroy the divine tree.

Then Xue Luding asked for another Shab insect. This time, he used the blood of the curse to cultivate special divine tree cells, which gradually grew into a plant. Xue Luding simply plucked a branch as a bullet, and the wooden divine tree bullet hit the corpse of the Shab insect directly.

"Crack!"

The hard shell of the Shub insectoid was rooted the moment the Divine Tree bullet hit it, and then the roots of the Divine Tree frantically burrowed into the insect's carapace, rapidly draining the insect's life force.

"Brother, what are you doing..." When 5332 returned to refuel the flamethrower, he suddenly saw the experimental progress on Xue's side. He saw the divine tree growing wildly inside the insect's body, bursting out branches and wood spikes from the inside out, turning the still-living insect into a monster like a sea urchin.

That wasn't all. Immediately afterward, the branches and thorns seemed to have encountered a natural enemy, quickly decaying and withering. Within minutes, the once vibrant and flourishing divine tree died, turning into withered branches indistinguishable from ordinary rotten wood.

Xue Dinglu's lips curled up, and he even shouted excitedly, "Yada thief! We did it!"

During the battle with the Ninth Apostle, Xue Lude also learned from the Star Squadron's data that those non-pure insects would become nutrients for the Divine Tree. At this moment, Xue Lude understood that, at least in terms of status and strength, the Divine Tree must far surpass the insects.

Otherwise, it wouldn't be the sacred tree sucking up insects, but the Zerg eating the tree.

Xue's Law is essentially just inserting a branch into the insect's body and letting it grow wildly; at most, it's just adding a self-destruct system to the branch.

Upon seeing 5332, Xue's Law said something that left 5332 completely baffled.

"5332, have everyone collect the insect corpses and create an environment similar to the biological broth. I've found a way to specifically attack the insect race. With this weapon, you can easily defeat any insect monster except for the Insect God!" Xue Luding excitedly pointed to the insect that was being burst open by the branches from the inside out and said excitedly.

This is a strategy of using one tiger to devour another.

The sacred tree is used to kill insects, then bacteriophages are used to kill the sacred tree seedlings. Finally, the bacteriophages fall into nature and die collectively within a few minutes, achieving a perfect cycle.

He didn't even intend to keep this method a secret. Since there were many members of the Starfleet here, Xue Lude decided to give this gift to everyone in the Starfleet.

……

Soon after receiving the news, a man over two meters tall, somewhat resembling an elf, arrived at Xue Luding's place and said, "Sage, I heard that you have developed a weapon specifically for attacking the Shub insectoid race?"

Starfleet has never had a good way to deal with the Shub Zerg, and often starts with the Star Destroyer Cannon.

Or simply monitor the insect swarm's movements continuously and eliminate these damned creatures before the insect plague breaks out.

Their method of eliminating the Zerg was to use the purest energy attack to completely annihilate them, thus rendering their contamination ineffective.

Furthermore, the swarms are numerous and their individual combat capabilities are also strong. The pure-blooded Zerg queens are at least near-Tier 5, which makes them difficult for many ordinary Starfleet members to deal with.

It can be said that the Zerg swarm accounts for at least half of the workload of the entire Starfleet.

They have studied many viruses or poisons targeting insect swarms, but often after killing some insects, the remaining swarms quickly adapt, rendering the viruses ineffective.

However, Xue, who was also an apostle, understood that the vast majority of insects' fate was to become nourishment for the divine tree. Therefore, even under the control of the sixth apostle, he would not allow the insect swarm to have the ability to turn against the divine tree.

Therefore, at least in the underlying code of the insect swarm under the Sixth Apostle, the insects' status is always lower than that of the Divine Tree.

Then let's use magic to defeat magic, use natural disasters to fight natural disasters, and use the divine tree to kill the insects!

Xue Lude looked at the Starfleet member who had come to meet him and asked, "Didn't the Starfleet ever consider using the power of the Divine Tree to deal with the Zerg?"

In the old man's memory, Xue Law knew that the ancient predecessors of the interstellar column would also ride the divine tree to accomplish some impossible things, and they even had the absurd plan of having a divine tree the size of a planet push a black hole.

To everyone's surprise, this high elf-like fellow instantly wore a constipated expression and then said, "We've done similar technology before... but the result was that the Divine Tree Saplings proliferated on several planets."

Xue Law: "..."

"After killing the insects with the Divine Tree, the Divine Tree would grow into an even more troublesome enemy, which would cause even greater disasters, so we abandoned this research. But you, Sage, are different; you have actually created a product that can restrain the Divine Tree." The high elf did not hold back his praise.

However, Xue was a little embarrassed, since this bacteriophage was another one he had researched, and he had only further modified the original strain.

Soon after, Xue Lude handed over the divine tree and the bacteriophages within it to the high elf, who excitedly returned to headquarters with the research findings.

After initial testing, the commander-in-chief of the Starfleet immediately declared, "Mass production!"

……

Under Xue's arrangement, a large number of insect corpses were piled into a cooled glass pit, densely filled with tens of thousands of insectoid corpses.

And Xue Dinglu did what he was supposed to do as the "Thirteenth Apostle" for the first time: plant trees!

He planted the divine trees on the corpses, and soon, these divine trees absorbed the nutrients from the insect corpses and grew wildly.

However, once it grows to the height of a person, the cursed blood and the bacteriophages within it can be controlled to suppress its growth rate. Then, branches can be continuously pulled out and crafted into special weapons.

Whether it's bullets, arrows, cannonballs, javelins, or even crafted into longswords and spears, they will all be among the weapons used in the special attack against the insects.

The shields made from them will also provide special protection against swarms of insects.

However, the drawback of making it into a melee weapon is that after using the Divine Tree Greatsword to cut down an insect, the sword might immediately and eagerly parasitize the insect's body, completely disregarding who the host is.

Furthermore, if someone is accidentally injured by their own weapon, the Divine Tree Cells may instantly go berserk and devour the host through the wound. Although the bacteriophage will also act immediately, by the time the bacteriophage takes effect, the host being devoured will probably be almost dead.

This could be considered a very dangerous weapon, but for the world today...

For those who yearn to reclaim their homeland, launch a counterattack on Rongdu, and rightfully reclaim their planet from the Iron Curtain, such a price is entirely acceptable.

The main reason is that the cost is low.

Soon after Xue Lude taught them the technical details, a Divine Tree processing assembly line factory and the production of Divine Tree warheads were established here.

……

In just two days, this weapon with the Divine Tree warhead was put into actual combat.

The army had already conquered several cities, and when they arrived in a major economic city that was once part of the super Iron Curtain, they discovered Tier 5 Zerg warriors there.

This warrior seemed to have absorbed a lot of nutrients from the earth's veins, making it extremely large. Even when lying on the ground, it was over a hundred meters tall, resembling a terrifying prehistoric monster.

then……

After being swept by the divine tree's bullets several times, its entire body was covered with branches that eroded it. The plant's roots desperately absorbed nutrients from its body and continued to grow inside. The dense branches and roots completely imploded this Tier 5 warrior from the inside out.

According to the recollections of humans who witnessed this scene:

I used to think that insects were inherently evil. All living things feel pain, fear, and terror, but insects don't. But that day, after witnessing the hysterical roars of the Zerg warrior and watching the branches crush its carapace, and the tree completely exploding from the inside out, I understood...

These insects have probably met their true demise! From today onwards, the swarm's doomsday has arrived.

Chapter 318 The End of the War, The Banner of the Iron Curtain of Freedom

From that day on, a huge factory appeared around the newly established outpost.

The purpose of this factory was to process the branches of the divine tree that grew in the deep pit named "Endless Corpse Insects," then process these branches into bullets, which were then loaded into the magazines of the soldiers on the front lines.

Therefore, within just a few days, the factory, operating at full capacity, rapidly produced 50 billion warheads per day.

Even now, under the divine tree planted by Xue Lude, roots are densely distributed everywhere, and the number of insect corpses at the bottom of the pit has reached hundreds of millions.

Both the human coalition warriors and the dreadnoughts on the front lines were equipped with the corresponding warheads. From then on, the Zerg swarm basically had no units that could directly threaten the entire coalition forces.

Even the Swarm Warriors, these individual members of the Shub race that are frantically evolving towards combat, will be devoured by the rapidly growing Tree amidst a barrage of Tree warheads.

The battle lines are constantly expanding outwards. Even though the swarm still numbers over ten billion, their lives are as fragile as candles flickering in the wind in the face of the current coalition forces.

Today marks the day when the allied forces will launch a counterattack into Rongdu, the capital of the super iron curtain.

In the distance, giant beasts tens of meters tall, escorted by fearless mechs, carried a terrifying giant vehicle a hundred meters tall. On a plain 50 kilometers away from Rongdu, the giant vehicle stopped and stretched out on the spot, instantly transforming into a giant building more than a hundred meters tall, just like a Transformer.

This is the technology of the Freedom Curtain, a mobile fortress called the Frontline Base Vehicle. This steel structure will rapidly expand and form an outpost here, becoming the next base to continuously provide logistical supplies and support to the front lines.

Tomorrow will be the Rongdu counterattack, the last major battle on this planet.

Because the last Zerg Queen resides there, and all the high-ranking members of the original Super Iron Curtain are also in Rongdu.

For the Free Iron Curtain forces who were launching a counterattack on Rongdu, the sight of their distant capital swarming with insectoid creatures was a source of intense rage.

The high command of the Iron Curtain did not lose the war, but rather, after discovering that the Zerg could communicate, they took the initiative to communicate with the Zerg Queen and subsequently surrendered to her.

In other words, the higher-ups of the entire Iron Curtain basically didn't put up any decent resistance; they surrendered to the insects and were then all twisted and assimilated into pseudo-insects.

Consequently, the entire Rongdu and almost all of the areas controlled by the Super Iron Curtain were completely devoured by the swarm within a single day, turning into a complete insect hive.

Even while the remaining combatants were still fighting back against the Zerg swarm, the officials of the Super Iron Curtain issued countless orders from the capital, sending frontline soldiers to their deaths, causing the battle line to completely collapse.

In terms of sheer hatred, those high-ranking members of the Super Iron Curtain who surrendered to the Zerg are more hated by the people of the Free Iron Curtain than the Zerg themselves.

So in a very short time, all the attacking swarms of insects were burned, and their corpses were thrown into the newly prepared insect pit. Then, twisted saplings grew out of the pit and became the source of bullet materials for this front-line base.

Several production lines for manufacturing Divine Tree bullets were also transported here directly from the base vehicle. After the Divine Tree was fully grown, they immediately began a frenzied production of billions of bullets per day.

When the outpost was established, a large swarm of insects seemed to be launching a desperate counterattack, but it was completely ineffective. They all eventually became good brothers in the Ten Thousand Insect Pit, becoming part of the nutrients provided to the Divine Tree.

Perhaps when their souls come into contact within the divine tree, they will say to each other that it has been a long time since they last met.

On the morning of the sixth day after the fall of the Iron Curtain, the Allied forces checked the number of Sacred Tree bullets in their hands; each man had 200 rounds.

The Dreadnoughts also checked their fuel reserves, which were more than sufficient.

Nearly 40 million Dreadnoughts, 10,000 Super Beasts, and nearly 10,000 soldiers from the Freedom Curtain have come here together.

Unlike the past when they resolutely rushed towards the coastal defense line after the military parade, this time, everyone's faces showed only a desire for victory, not the desperate look of someone ready to die.

The temporary leader of the Free Iron Curtain, Aigar, stood at the front of the army alongside 5332. No further encouragement or arrangements were needed. The plan to retake Rongdu had already been formulated when the counterattack reached the Super Iron Curtain, and everyone understood how this battle should proceed.

"Proceed according to plan, attack Rongdu, sweep through it step by step, and thoroughly implement the scorched earth plan!" Ai Gaole said.

"Rongdu is no longer our homeland. It is the enemy's lair and will be the final grave of those former super Iron Curtain war criminals. All troops, attack!"

"boom!"

Heavy artillery shattered Rongdu's city walls. The plan was for the allied forces to attack Rongdu simultaneously in three columns, with the main force still consisting of the dreadnought mechs.

The Scorched Earth Siege Machines can instantly transform into Zerg killing machines, and their scorching inferno can turn all buildings, soil, earth, and Zerg swarms into a combination of glass and obsidian.

Any swarm of insects that dares to face the sea of ​​fire will be completely burned.

Next came the heavy machine gun squadron. Some of these soldiers were soldiers of the Freedom Curtain, while others were Dreadnought mechs who had changed their Scorched Earth mech uniforms into Ranger uniforms, replacing their Scorched Earth flamethrowers with heavy machine guns that could fire thousands of rounds per second.

Every bullet in these heavy machine guns is a Divine Tree bullet. These Ranger-type Dreadnought mechs have also transformed from their original scout-type mechs into specialized mechs designed to deal with Zerg warriors and the Zerg Queen.

The torrent of steel advanced into Rongdu, and after the Zerg warriors and the Dreadnoughts made contact, the chalky battle truly began.

Fire and explosions swept through the entire city of Rongdu. At this moment, the high-ranking members of the Super Iron Curtain who had originally surrendered to the Zerg became meat shields to fill the gaps. But in reality, the moment they turned into Zerg, the original people were already dead.

Those that survived were nothing more than insects with memories of their past lives, disguised in human skin.

Even when these insects in human skin disguised themselves as old people, women, and children, and pitifully approached the Allied forces, pleading for help, no one sympathized with them. All that awaited them was a burst of divine tree bullets or flamethrowers scorching the earth.

Just as Xue's Law said before the war, do not have any sympathy for the swarm. Even if you see familiar faces and pitiful children, they are just the enemy in disguise. They have no feelings, no pain, and no fear.

Then the momentum of the battle seemed to gradually slow down, just like when the insects were forced to participate in street fighting in West Sea City on the Beast Star, and were dragged out for dozens of hours by the Beasts and the people of the Freedom Iron Curtain in that brutal street fighting.

Now, the coalition forces are also hampered by the Zerg's brutal urban warfare.
