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

Chapter 201: The Power of Ion Laser Cannons, Retreat and Street Fighting

"Ion Laser Cannon lv30/39, Gold Quality"

"Upgrade points: 0/2, basic damage 1000, effective range 20 kilometers, unlimited instantaneous times, focused ion beam cannon: 10/10, energy recovery speed 1/h"

「New additional attribute: Laser energy focusing」

"Laser Focus: After locking onto a target and firing, each ion beam cannon lasts for 10 seconds. In addition to the basic damage, it increases by 500 damage per second as the temperature rises."

"Note: Damage decreases as the attack distance increases. The critical point is ten kilometers. The total damage decreases by 10% per kilometer beyond ten kilometers."

「Can be switched to lv29 electromagnetic gun mode」

"Evaluation: This is a golden weapon that can destroy multiple layers of defense through high-temperature burning. The maximum temperature can reach 6,000 degrees within ten seconds, and it can penetrate everything. If it doesn't work, then let's have another shot!"

"Note: You have obtained the energy for synchronous cross-level upgrade, and can start upgrading yourself when the status is intact."

Lin Feng's mouth curled up slightly. According to the laser energy focusing of the ion laser cannon, the damage can be increased by a total of 5000 points within ten seconds. Adding the basic damage of 1000 points, the total maximum limit is , which is enough to break through the defense layer of the third-stage mid-stage Zerg Queen.

If dealing with a Queen Mother in the early stage of the third stage, it is only necessary to continue irradiating for four or five seconds.

For the slow-moving queen, the continuous burning of the laser cannon, coupled with its attack at the speed of light, was impossible to defend against and she had nowhere to hide.

The maximum attenuation threshold of ten kilometers also allows Lin Feng to return to long-range attacks. He no longer has to rely on the melee equipment Tiger Tooth Chainsaw Sword to break through the defense and engage in close combat at great risk, as he did before when he killed the Queen Mother of Jiangbei.

Unfortunately, the underground space is too narrow to fully utilize the ion laser cannon, and unless the Queen Mother Jiangbei breaks out of the ground again, the ion laser cannon can be used to its maximum effect, truly achieving a kill without causing any injury.

After a sigh, Lin Feng didn't think any more and immediately raised the level 30 ion laser cannon in his hand.

At this moment, after switching modes, the entire cannon is three meters long and nearly half a meter wide at its widest point. The gun body is no longer the previous slender launch tube, but has become a regular hexagonal orange light accumulator with a cross-section like honeycomb coal, emitting a blazing light.

Ion laser cannons are completely different from traditional guns and cannons, and their appearance is more like future super weapons in science fiction movies.

As Lin Feng raised the ion laser cannon weighing hundreds of kilograms and aimed it at a dozen tank beetles in the distance, he was ready to test his skill...

The defensive power of these tank flame armors is comparable to that of a second-level peak tiger-spine worm. The shotgun shells hitting its thick outer armor can only leave a small shallow mark at most, let alone break through the multiple layers of defense.

Apart from the Tiger-Tooth Chainsaw Sword, only Shen Jie, who has activated the killing state of mind, can fight against it.

But at this moment, Shen Jie was also restricted by several late-stage second-order warrior hunter insects and the tank flame armor. He could not break out of the situation in a short period of time and could only focus on defense.

This caused the other genetic warriors to be at a disadvantage when facing the joint attack of multiple second-order Zergs. Many warriors were careless and were ambushed by the warrior hunters.

The crisis must be reversed as soon as possible!

At this moment, as Lin Feng held up the ion laser cannon, the hexagonal energy concentrator at the muzzle began to split into six long energy concentrating rings, which gradually accelerated their rotation around the central honeycomb muzzle.

The next moment, a bright orange-red beam of light shone directly on the back of a tank fire beetle at the speed of light. The distance between the two sides was exactly eight or nine kilometers, which was less than the critical point of ten kilometers, so the laser damage would not be attenuated.

At this time, Lin Feng also discovered that, under the constraint of the muzzle, the entire beam of light could only maintain a circular size of one meter in diameter within ten kilometers, and beyond ten kilometers it could no longer maintain stability and continued to spread, causing damage attenuation.

As for now, the group of tanks and flame armors in the distance were all exposed to the full attack range.

As the laser begins to gather energy over time, the temperature rises dramatically and the damage also soars.

From the basic one thousand points of damage, it increased to two thousand points in two seconds, directly piercing the tank's fire armor which was protected by a shell more than one meter thick.

The color of the laser beam also changed from orange-red to orange-yellow, and gradually emitted a dazzling golden light.

After easily killing a tank fire beetle, Lin Feng did not stop, but flew directly into the air, aimed at a row of tank fire armors in the distance, and began to rotate the muzzle of the ion laser cannon, destroying them one by one with laser beams.

During the process, the lasers streaked across many second-order tiger-spine worms, and their limbs were instantly separated by the cut ones.

It can't stop the light cannon that can harm thousands of people.

The ion beam cannon's sweep lasted for half a minute, consuming all the energy of the three spare shots.

In the end, all that was left was a pile of broken insect corpses, with blood and flesh flying everywhere. There were large gaps in the body, which were all cooked meat and charred by the laser. The strong smell of burning was wafting around, which looked shocking.

This is the level 30 ion laser cannon, which is comparable to the power of the third stage gold quality weapons.

Sixteen tank fire beetles and dozens of second-level tiger-backed insects were all wiped out within half a minute.

If it wasn't for the fear of hurting the genetic warriors fighting with it, it would even be able to sweep away all the warrior hunting insects.

Under the attack at the speed of light, no second-level life form can escape its locked irradiation within a second.

Aim and you will die!

This is the essential feature that distinguishes laser cannons from traditional artillery shells and even electromagnetic cannons.

The strike speed of three hundred thousand kilometers per second, even if it requires charging to cause high damage, is enough to cause a real dimensionality reduction attack on the life on the planet!

After all, at this speed, the speed of sound and hypersonic speed seem to be no different from being still.

Dealing with the warrior hunter bugs with relatively weak armor defense is a piece of cake. You can kill them one by one. There is no need to charge the ion beam cannon. Just rely on the basic damage of one thousand and instant fire.

The only thing that needs to be paid attention to is whether Lin Feng’s own reaction speed and the locking aim of the moving gun muzzle can keep up with the enemy’s escape and evasion.

However, at present, except for the second-level wind-wing insects that fly at high speeds, no other Zerg can burst into a speed of thousands of meters per second.

And when Lin Feng himself advances to the third stage, with the blessing of his mental and physical attributes, his nerve reaction speed will definitely be further improved. By then, even the wind-winged insect will find it difficult to escape the attack of the laser cannon.

After all, when dealing with high-speed moving targets, laser cannons are extremely accurate and can be called the nemesis of high speed.

At this moment, Lin Feng had not yet entered the third stage, but he had already ascended the battlefield like a god of war, holding a laser cannon and bringing down heavenly punishment. In just a few dozen seconds, he eliminated the top combat power of the Zerg...

Directly change the entire course of the battle!

Without the cover of the Tiger-Spine Beetles and Tank Fire Beetles, the remaining dozen or so Warrior Hunter Beetles fled the battlefield one after another. The Zerg Queen who was controlling the battle behind the scenes, after realizing the sudden change in the situation, directly ordered the Zerg swarm surrounding the fleet to speed up their evacuation.

For a moment, the entire battlefield was marked by a one-sided and massive defeat of the Zerg.

Those second-order tiger-backed worms were even more panicked and fled back to the territory of Haicheng in a reckless manner, resulting in a large number of trampling incidents. At least thousands of black-backed worms died tragically under the sharp feet of the second-order tiger-backed worms.

Lin Feng originally wanted to fly forward and lead the second-level battle group to pursue the victory and completely eliminate the second-level Zerg, but the dreadnought battleship slowly approaching from behind interrupted his steps.

Chen Yanyan's familiar voice came from the bow:

"Stop chasing, we have to go back to defend!"

Lin Feng was stunned and his figure stopped in mid-air.

Then he flew to the bow and saw Chen Yanyan, who looked haggard, and explained the reason:
"The other half of the Haicheng Zerg is not here. The Queen Mother took advantage of the fleet being surrounded and arranged for them to take a detour and attack the second line of defense."

"Li Ran sent a message saying that many parts of the defense line have been breached by the insect tide. We need to send people back to support as soon as possible!"

Lin Feng frowned slightly. This was a good opportunity to severely damage the Queen Mother of Haicheng. If he let the remaining hundreds of second-order tiger-spine insects escape, the pressure of defending Jincheng in the future would undoubtedly increase several times.

But when Lin Feng looked back, most of the second-level battle groups on the front line, whether genetic warriors or ordinary members, were exhausted in this tug-of-war. Except for the more than 20 melee groups armed with chainsaw swords that he brought back, the rest of the members, including the first-level awakeners on the battlefield, had been fighting for several hours, from morning to noon.

Not only was he physically weak and mentally depressed, but the breakfast he had eaten had already been digested. Awakened people needed more food and water than ordinary humans to sustain their bodies' massive consumption.

The impact of hunger on combat status is no less than that of being injured, and combat effectiveness will directly drop to a lower level.

In addition, if they chase into the Zerg's hinterland, they will most likely face the personal destruction of the Queen of Sea City.

A level 32 Jiangbei Queen Mother had already caused Lin Feng severe mental damage and he almost fell over.

The Queen Mother of Haicheng is the only mid-stage third-level Queen Mother in the entire Jiangnan region. Even if Lin Feng reaches level 30, it will be difficult for him to fight against it.

Not to mention that there are genetic warriors in the team, these time bombs are easily affected by the Queen Mother's mental control.

Taking into account various practical factors, Lin Feng hesitated for a moment and decided to follow Chen Yanyan's advice.

Return to the capital and rescue the camp first.

The order to retreat was immediately issued.

But before that, the fleet must first clean up the battlefield and make up for the losses as much as possible.

Lin Feng took a quick look from mid-air and saw that at least a dozen tanks were damaged and broken down in this decisive battle. Some were even unfortunately attacked by tiger-backed insects. Under the bite of their giant jaws, the entire tank was split straight in half from the middle, and more than half of the crew members were killed on the spot.

The devastated battlefield was filled with blood and flesh flying everywhere, Zerg and human limbs were scattered everywhere, and there were many wounded soldiers with missing arms and legs, wailing in pain.

After calming down, Lin Feng immediately arranged for Chen Yanyan to deal with the wounded first, and then led the members of the second-level regiment who were still in good condition to rush to the second line of defense 20 kilometers behind the rear.

…………

A few minutes later, Lin Feng and his party arrived below the defense line.

I saw that the high wall fortifications built on the other side of the moat around the city were now in ruins.

Nearly a hundred second-order tiger-backed worms, leading the remaining tens of thousands of first-order black-backed worms, launched a fierce attack on the ten-kilometer-long second line of defense.

The twenty-meter-wide moat around the city was filled with the corpses of Zerg who died in the siege, as many as thousands.

More than a dozen blockhouses in the main fort were completely destroyed in the attack by the giant jaws of the tiger-backed worm. A gap hundreds of meters wide appeared in the entire defense line. The entire city wall broke and collapsed, leaving behind a field of Zerg and human corpses.

Hearing the sound of artillery fire coming from the city, Lin Feng couldn't help but worry about the safety of Liu Yueqi and others.

Shen Jie, who had just released himself from the winged tiger's berserker form, turned into a stream of light, spread his wings and rushed into the city.

The second-level members behind him, led by Lin Feng, entered the city one after another and cleared out the remaining Zerg in the city.

Soon after Lin Feng dealt with several second-order tiger-spine insects, he found Li Ran, who was organizing a defense line in front of the university town to resist the insect swarm's attack.

The second-level regiment faced an ordinary Zerg tide and slaughtered them easily like a tiger entering a flock of sheep. Even though there were only sixty or seventy members who returned with Lin Feng, they instantly suppressed the Zerg offensive in the city area behind the defense line.

Seeing Lin Feng return safely, Li Ran finally felt relieved.

Lin Feng's return means that the decapitation plan has been successfully completed, so this decisive battle and so many sacrifices are all meaningful!

The dead team members did not die in vain.

Soon, with Li Ran's report, Lin Feng had a general understanding of the war situation in the camp.

There are more than 5,000 soldiers, excluding the 1,200 recruited by the fleet and the 300 late-stage first-level soldiers temporarily transferred by Lin Feng, there are still 3,500 left.

It sounds like a lot, but most of these 3,500 soldiers are only at the early first level, although they have basically all achieved awakening after the fleet’s crazy training.

However, due to the rush to complete the work, the awakening progress was not high, and most of them remained in the initial stage. Only six or seven hundred out of three thousand five hundred people entered the middle stage of the first stage.

Their overall strength may be even worse than the three hundred first-level late-stage elite soldiers brought by Lin Feng.

But neither Lin Feng nor Chen Yanyan had expected that the Queen Mother would have such high wisdom in war, and her strategic vision was no less than that of the commanding geniuses on the human side.

It knew very well that it could not completely eliminate the human fleet in a short period of time unless it took action personally.

Instead of paying a huge price to fight the fleet, it is better to bypass the fleet and first solve the rear of the human defenders, that is, the base behind the second line of defense.

It is much easier for the Zerg to deal with fixed defensive fortifications.

It only takes a few hundred second-order tiger-spine insects as the main force to attack the city and break the formation, and they can lead tens of thousands of low-level Zerg to clear out the logistical support of humans.

A fleet without a way to retreat and losing logistical supplies will naturally become a desperate struggle, fleeing in a panic as it is surrounded and blocked by the insect swarm.

The Queen Mother of Haicheng's plan to cut off the source of the problem was perfect.

Especially when Lin Feng had to implement the decapitation plan and needed to withdraw some of the defending forces, the entire second line of defense in the rear and the temporary camp appeared to be strong on the outside but weak on the inside.

However, what it did not expect was that the person in charge of setting up the second line of defense and the commander of the entire camp was Li Ran, who had experienced many major wars.

As early as when the fleet that went out to seek a decisive battle was surrounded by a swarm of insects, Li Ran, who sent out scouts and received the news, instantly sensed a hint of crisis.

Then they arranged the defenders within the defense line and began to gradually retreat back into the city, relying on the urban buildings in the West City District, preparing to fight street battles with the Zerg.

To avoid the problem of insufficient garrison manpower.

Street fighting can effectively reduce the advantage of the insect swarm on the plains and the sweeping charge of the army.

If the black-backed beetle is compared to a light tank and the tiger-backed beetle is compared to a heavy tank, it is easy to understand why Li Ran chose to place the battle in the urban area rather than the more solid second line of defense.

After experiencing the defeat of Wucheng's first line of defense and the street fighting led by Lin Feng in Jiacheng, Li Ran knew very well what to do when the enemy was at the gates.

Although there were also many casualties in the street fighting with the Zerg, it was better than the result of the defense line being breached and then being bitten and surrounded by the Zerg and wiped out...

Obviously, street fighting is more valuable, and it can also slow down the Zerg's offensive and wait for rescue to arrive.

It was Li Ran's decisive decision that enabled him to quickly complete the rotation of guards and the arrangement of outposts and firepower points in the urban area, which prevented the defense line from being breached this time without causing too much damage.

Of the 3,500 soldiers, only one-fifth were killed.

The manpower was successfully preserved.

What made Lin Feng feel relieved was that the university town camp had not been breached, which meant that Liu Yueqi and others were still safe.

Hearing Lin Feng mention this distinctive girl, Li Ran smiled bitterly:
"This guy brought a small team and rushed directly into the city to participate in the street fighting!"

"And he fought more and more fiercely. In just two hours, he killed more than fifty black-spine insects with a long sword. He has already entered the late stage of the first stage."

"Ten minutes ago, after a short rest, she rushed into the city with a chicken leg in her mouth, intending to find a lone tiger spine worm and complete the second-level deep awakening..."
