End of the World: My Items Can Be Upgraded Infinitely.

Chapter 155: Sneaking underground, a strange journey into the insect nest!
After saying that, the second-level legion squad behind Lin Feng raised their shotguns. At the same time, Lin Feng also raised his tiger-tooth chainsaw sword, ready to go.

Once tiger-backed insects pass by, they will be killed with lightning speed!

However, at this moment, Long Yi, whose introduction was interrupted, suddenly spoke in a low and hurried voice:

"Wait, don't do anything yet!"

Lin Feng turned his head away, frowning slightly.

From his telepathic skills, he could see that there were several second-order tiger-spine worms two hundred meters away on the left, and they were about to pass through the wide wormhole in front of them.

If you prepare in advance, you may be able to win it in one fell swoop.

But Lingyi continued to explain:

"You have a lot of black-backed beetle scent on you, and this ventilation duct is ventilated upwards, so your whereabouts have not been revealed yet!"

"Those tiger-backed insects are just patrolling as usual. There's no need to expose our presence just for a few tiger-backed insects!"

Lin Feng frowned slightly:

"Patrol? If there is a certain route, will it pass by an important secondary insect nest?"

Ling nodded slightly, and when he saw that Lin Feng had put down the tiger-toothed chainsaw sword, he breathed a sigh of relief and continued:

"That's right. As long as we follow them, we can find out the approximate distribution of the underground insect nests, which will make it much easier to find them."

"Besides, with me here, I can help you cover up, especially your mental fluctuations, making it difficult for the Queen Mother to detect."

"But once we find the second-level insect eggs and destroy them, the Queen Mother will definitely be alerted, so that's when we can break out of the insect encirclement."

"If we launch an attack now, the enemy will definitely move all the second-order insect eggs to the deepest mother nest, as they have already received the warning from the Queen Mother of Sea City..."

"With the limited manpower we have now, we can't face the Queen Mother's personal death underground."

Lin Feng took a deep breath, nodded, and signaled his team members to put away the shotgun and sneak along the wall of the cave.

After slowing down, Lin Feng asked curiously:

"Isn't the Queen Mother's movement speed underground very slow?"

Lingyi walked to the front and led the way, saying as he walked:
"It takes a lot of energy to control tens of thousands of low-level Zergs. To control the second-level Zergs, most of the Queen Mother's mental power is invested in the entire Zerg, which is why she has such a bloated and huge body. She also consumes a lot of nutrients and energy every moment to replenish her brain state."

"The movement speed is slow, which is completely a drag. Moreover, every time we move forward, we have to cut and relocate the large biological mother nests in the insect nest."

"We need to mobilize tens of thousands of scarlet beetles."

"So the fastest speed of the Zerg invasion and expansion is only about three or four kilometers a day."

"Unless the Queen Mother feels her life is threatened, she will stop at nothing to release the mental control over the entire Zerg swarm and move forward with all her might..."

"In that case, it can probably reach ten meters per second. If it comes from the deepest part of the ground, the distance is seven or eight kilometers."

"After we have plundered the second-level insect eggs, we will have at least a quarter of an hour to escape from the deepest nest where the queen is. But if the queen, out of caution, does not take action herself, then we can just harvest them normally."

"Generally speaking, unless all the second-level insect eggs are destroyed, it will not fight for its life. After all, the price of doing so is at least four or five days for it to recover its vitality, be incorporated into the insect swarm, and reorganize its organizational structure."

Lin Feng nodded secretly. It seemed that the price that Ling Yi paid forcibly to break out of the ground outside Jiacheng in order to avoid the situation from getting worse was far more than just releasing his domain and lowering his own level.

Similarly, unless faced with a life-and-death crisis, the Queen Mother would never give up controlling the swarm and personally go out to kill the enemy.

And a very cunning being like the Queen Mother of Sea City would not reveal her specific coordinates just because of a few second-order Zergs.

After all, although human nuclear bombs pose no threat to the mother nest five hundred meters underground, ground-penetrating missiles have been used in actual combat in spaces one or two hundred meters deep.

While the two were discussing in a low voice, the one in front suddenly shut his mouth and stopped, then waved his hand to signal the fully armed second-level legion squad behind to hide.

Lin Feng narrowed his eyes and through the ink-colored lens on the armor in front of his eyes, he saw a fork in the road about ten meters away from the crowd.

After walking down for more than a hundred meters, they finally entered a wide wormhole with a diameter of twenty meters. This is a channel for the Zerg army to migrate at high speed, and it is also the area where the second-level Zerg usually patrols.

And it goes all the way down to the secondary insect nest deeper underground!
When everyone pressed tightly against the cave wall...

Soon, a series of thudding sounds were heard from the wall that was reinforced with the red beetle's mucus!

Boom! Boom! Boom! Boom!

As the chaotic knocking sounds got closer and closer, a group of second-order tiger-backed insects suddenly appeared at the entrance of the cave in front of everyone.

Lin Feng and others held their breath and concentrated.

Try to hold your breath as tight as possible and stand still like a fool.

These tiger-backed worms walk very slowly and explore everywhere to make sure that there are no other unknown creatures hiding in the corners or cracks of the walls.

Obviously, the invasion of awakened people on the surface has made the queen mother underground more cautious.

Control the tiger-backed worm patrol team and conduct a careful investigation.

After they left one after another, Longyi looked back at Lin Feng, nodded, and then took a step forward, leading the people behind him, one by one into the widened wormhole.

The second-tier legion team continued to hide their presence, ignoring the red beetles transporting supplies around them, and shuttled between the insect swarms under their feet...

Stealthily following the swarm of tiger-backed insects a few dozen meters away.

As their patrol route began to extend deeper underground, Lin Feng and Long Yi became more and more excited.

Soon, when everyone had dived to a depth of two hundred meters underground, they finally saw a second-level insect nest appear before their eyes.

As the second-level tiger-backed beetle patrol team suddenly stopped, everyone also crawled on the ground, hiding among the red beetle swarms, carefully observing the scene in the distance.

Some kind of luminous slime mold was growing on the nearby cave wall, and the faint green light was like the white phosphorus will-o'-the-wisp burning in a cemetery, illuminating the dark underground tunnel.

Although the vision was dim, the ten people present were all second-level awakeners, so they could see it clearly.

At the entrance of the insect nest not far away, two pairs of giant jaws poked out and touched the patrolling tiger-spine insects.

It seems like an intimate greeting.

This is because the two communicate through the pheromone-releasing organs under the giant jaws to confirm the safety of the surrounding area.

Each second-level insect nest has special guards.

The further down you go, the stricter the Zerg's vigilance becomes.

After the two sides exchanged information and the patrolling group of second-order tiger-backed insects left, everyone, led by Lingyi, continued to move forward with their heads down to avoid being discovered by the tiger-backed insect guards hidden on both sides of the cave entrance.

Half-crouching and hiding among the swarm of red beetles, after passing through the cave, Lin Feng stretched out his hand and pressed down on Long's shoulder.

The other party turned around and saw Lin Feng gesturing with his hands, asking if that was the destination of their trip.

Because Lin Feng detected through telepathy that there was a huge light source in this second-level insect nest.

It was the same as the last time when I passed through the biological furnace of the riverside shipyard and entered an insect nest.

There is also a large biological factory in the second-level insect nest behind him. Through telepathy, it is fed back into Lin Feng’s mind as a large bright light source.

This shows that it contains extremely high life energy.

However, Long Yi just shook his head slightly.

Then continue forward.

When they were nearly a hundred meters away from the entrance of the insect nest, she whispered to everyone:
"There are no second-order insect eggs there, but a centralized hatchery for first-order insect eggs."

"The basketball-sized eggs bred from the queen mother's body are sent to the incubation nest. If there is sufficient food, it will only take three or four days for a first-stage black-spine worm to be born."

"Because it is a catalytic accelerated growth, the biological nest needs a high temperature and high heat environment to complete the metamorphosis from eggs to adults so quickly."

"In one hatching nest, there are probably nearly 10,000 black-spine insects hatching at the same time, and one third of them can be hatched to maturity every day. In an ordinary insect swarm, there are more than ten such second-level insect nests."

Lin Feng's face was solemn, and the people behind him were even more horrified. Such a fast hatching speed, plus the total amount being hatched every moment...

The war potential of each Zerg queen is stronger than that of a medium-sized country on Blue Planet.

No wonder I always feel that low-level Zergs are endless.

Seeing this, Long Yi shrugged and continued to explain:
"Although a third-stage Zerg queen can lay a first-stage egg every second, not every egg will successfully develop into an adult."

"Excluding the weak ones with insufficient innate abilities and some defective ones with mutations and deformities, only about 60% of the eggs can grow into first-stage early black-spine insects."

"So actually, the Zerg's active screening and elimination began as early as the beginning of their development. Although the low-level Zerg lack intelligence, they absolutely obey orders." "Such quality is several times stronger than that of ordinary human troops. Unless the queen mother is dead, there will be no large-scale rout."

During the narration, the swarm of red beetles around the crowd were still moving, making a chaotic creaking sound of footsteps, covering up the low voice of Longyi.

After hearing the first few sentences, Lin Feng fell into deep thought.

He was estimating the overall strength of the Zerg ruled by the early stage third-order queen.

As the incarnation of the Queen Mother, the information provided by Lingyi is definitely the most accurate.

Based on this, there is one insect egg per second, which is about 60 eggs a day. Even if the final yield rate is only %, more than first-order black-backed insects will be born in three or four days.

This is the maximum output of a normal swarm.

The Zerg Queen usually does not put all her resources into hatching larvae, so most low-level eggs are not in a hurry to hatch completely.

As I have introduced before, a perfect queen at the early stage of the third stage, that is, level 33, can control about low-level Zergs.

Taking into account that the second-level tiger-spine swarm will distract a large part of the energy, the size of the low-level swarm is usually maintained at just over 100,000.

The Zerg Queen is like a large computer. While maintaining the expansion of the Zerg swarm, she also needs to allocate reasonable computing power to each part of the swarm.

In this way, each biological hatching nest can hatch about three to four thousand black-backed worms every day, which means a total of about forty to fifty thousand.

Therefore, within a short period of time of one day, the Zerg can instantly increase the number of swarms by 50%.

Just as I introduced before.

The lv36 Queen Mother, who is in the perfect stage of the middle stage of the third order, has a low-level Zerg swarm under her command of to . After the explosion of troops, it can expand to a million within a day!
As long as we successfully defeat the enemy and plunder its biological resources, this rapid increase in troops in a short period of time can continue.

And if you delay it until the next day, it will be the original 100%!

The Zerg will continue to expand until every individual of the hostile race is killed!
In the future, if I want to hold on to a certain territory and engage in a decisive battle with the Zerg, I must have at least 100,000 awakened people to completely suppress the third-stage mid-stage queen within one day.

Destroy their underground hives.

Leave it no chance to catch its breath and explode its troops!
In a war of attrition, humans who are unable to produce in large quantities will always end up in failure.

With only 5,000 combat soldiers and hundreds of awakened ones under his command, Lin Feng can only use the high mobility of the fleet to carry out guerrilla harassment on the periphery.

In other words, before training all 5,000 soldiers into first-order awakeners, Lin Feng still does not have the ability to engage in a decisive battle with a third-order early queen.

At the same time, at least one well-equipped second-level legion must be formed to follow and assist him in entering the underground insect nest.

The last condition is that Lin Feng himself must have the ability to kill a high-level queen with tens of thousands of health points within ten seconds!
These three need to be done simultaneously...

Indispensable.

Thinking of this, Lin Feng looked at the group of second-order tiger-spine insects not far ahead, his eyes becoming more ferocious.

Long Yi was quick to sense something, and immediately turned around, put his finger to his lips, hushed, and shook his head:
"Don't release the murderous aura. You've already scared the nearby red beetles. The insects in the hive are very sensitive to this kind of aura."

Lin Feng nodded, took a deep breath, and calmed himself down.

The swarm of red beetles serving as worker insects nearby are the best camouflage for everyone, so they must not be scared away.

Soon, the swarm of tiger-backed insects in front stopped again, which meant that they passed by another secondary insect nest.

Everyone stopped and waited patiently.

This time, after they finished communicating and left, Lingyi did not stop. He continued to lead everyone to bend over and squat, carefully passing by the entrance of the insect nest.

However, most of the red beetle swarms near the team began to crawl into the entrance of the hive behind them.

Lin Feng frowned slightly. The large-scale departure of red beetles was not a good sign.

Ling Yi then explained in a low voice:
"Inside that is a waste biomass recycling nest, which is where the Zerg dragged back the bodies of their dead companions and sent them to the final destination."

"The valuable ones will be restored, and the worthless ones will be decomposed into nutrients to supply the entire insect colony."

“Recycle to reduce loss.”

At this point, Ling Yi stopped and looked at the scattered large red beetles around him. He raised his head and sniffed the air, his expression gradually becoming serious:

"It looks like the wormhole diagonally downward ahead is most likely the path to the second-stage hatching nest."

"These red beetles are transporting food. Each of them carries the scent of the mother nest. If we go any further, we will be easily discovered."

Lin Feng stood behind her, waiting for the next words.

At this moment, they have already gone three hundred meters underground and the target is about to appear before their eyes. There is absolutely no reason to retreat.

In these last few dozen meters, we must kill our way in, even if we will be exposed!

However, Lingyi quickly came up with a solution.

She took a deep breath, then stretched out her hand and grabbed the level 9 red beetle nearby.

Under her mental control, these large red beetles came obediently and then spit out some gelatinous substance from their tails and abdomens.

Ling Yi stretched out his hand and gently smeared the sticky liquid on his arms and neck.
As he did so, he explained:

"These are the biological populations on the surface. The nutrient solution extracted from them is similar to that in the second-level insect eggs."

"They are used to feed the queen mother. Tiger spine worms usually steal them."

"Because the biological populations living in each region are different, the final concentrated high-quality nutrient solution has subtle differences in taste and smell."

"This also becomes a characteristic that distinguishes different Zerg colonies, preventing foreign second-order Zerg from sneaking in and parasitizing."

"In the insect nest further down, the number of red beetles is scarce, and it is filled with the smell of food."

"Although it's disgusting, this thing can help us and is very easy to hide."

"What are you still looking at? Come over here and apply more, you're tired..."

"Well, you men's sweat glands have a strong odor, so you especially need to apply more."

The scene before them was beyond everyone's comprehension, and they all looked at their leader Lin Feng.

Lin Feng opened his mask and sniffed, confirming that there was a faint aroma of rice, which was probably related to the large tracts of farmland in Jiangbei...

Then he walked to Longyi and smeared the nutrient solution on the armor.

Shen Jie was the second one to come forward. He didn't mind it that much and couldn't wait to taste it.

He smacked his lips and nodded.
"Yes, this thing is similar to organic nutrient solution."

"But it also contains trace amounts of Zerg toxins. Ordinary people can't eat much, and Awakened people can't eat too much either, as it can easily upset their stomachs."

After hearing the previous words, the other team members were immediately delighted. However, Shen Jie's subsequent additions quickly extinguished their excitement and anticipation.

I thought I had found a treasure, but it turned out to be poisonous.

Lin Feng coughed lightly:
"Okay, don't be greedy for this little thing."

"Once we find the hatching nest where the second-level insect eggs are, we'll let you drink as much as you want in one go!"

"Now cheer up, this is the last leg of the journey and we can't afford to be careless!"

Everyone nodded and accepted the order immediately.

Then he smeared the liquid mucus spit out by the red beetle on his entire body armor.

Soon, under the leadership of Longyi, a group of people followed the tail of the red beetle, lay on the downward slope, and groped their way over carefully.

After a while, the slope under my feet gradually flattened, and now I have descended to a depth of 350 meters.

And here, the long-awaited second-level insect nest finally appeared.

Because not far away...

Next to the second-order tiger-backed insect swarm, there are several red beetles that are carrying huge insect eggs into the entrance of the second-order insect nest on the left side of the cave wall!
And that must be the important place for hatching second-level insect eggs!

Lin Feng clenched his fist and made a gesture.

Inform everyone and prepare for action!
