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

Chapter 103 Take a risk and kill the tiger-back worm with a life-and-death sniper!
The appearance of the tiger-spine worm quickly made Lin Feng realize the Zerg’s urgent determination to advance.

Every day they delay here, the evacuation of Jincheng will increase, until the entire city is emptied.

So even if the Zerg captured two cities in a row in a few days, all that would be left for them would be two large, useless concrete forests.

So Lin Feng did not doubt the appearance of the tiger-backed worm.

It is estimated that the Queen Mother discovered that the low-level army of black-spined insects was unable to conquer the human fortress, so she had no choice but to send out a small number of second-level insects to seek a breakthrough.

Right now, three tiger-backed worms are poking their heads out from a huge cave two kilometers away.

They act very cautiously.

Not too close.

Free at the limit of human vision.

It is difficult to detect it with the naked eye. After all, even a huge body of ten meters tall will become a small dot at a distance of two kilometers.

But if you use a high-power microscope or a telescope to view it, the bright yellow figure of the tiger worm will be extremely conspicuous.

Although Lin Feng guessed the Zerg's intentions, he found it difficult to understand their behavior at the moment.

Why do they frequently appear far away from the defense line?

Is it to intimidate the defenders in the fortifications?
Or seduce humans to go out of the city and fight?

Lin Feng prefers the former.

After all, in the wilderness, humans who have no advantage of terrain protection are still very vulnerable to second-order tiger-spine worms even if they hide in armored vehicles.

Under a bite force of more than ten tons, even the thickest alloy defense will be squeezed and deformed.

Lin Feng even worried whether the seven-centimeter-thick iron door behind the outpost bunker could survive three rounds of biting and hitting by the tiger-backed worm's giant jaws.

If the raid last night was led by the tiger-backed worms, the 201st Company in the fortress would definitely have suffered heavy casualties. If it had been on the front line of defense, at least several large main forts would have fallen, with casualties exceeding a thousand.

It's a pity that the Zerg missed the best opportunity to make a last-ditch effort.

Tonight, the human defense will be more experienced.

But Lin Feng could no longer wait until night.

As the tiger-backed worm's figure appeared and disappeared in the distance, the urgency in his heart continued to surge as he held the level 19 howitzer, whose upgrade had stagnated.

Urge him to act quickly.

But before that, Lin Feng was not stupid enough to fight a life-and-death battle with the tiger-back worm after fighting hard for a whole night.

He is not a machine and needs rest.

Just like soldiers on rotation, if you don’t get enough rest during the day, the blocking battles at night will be more difficult to endure.

Instruct Li Ran and Shen Jie to arrange for someone to keep watch. If a large-scale Tier 2 Zerg appears and attacks the outpost within sight, wake him up immediately:
"See? They are already two kilometers away, ready to move, waiting for the Zerg Queen's order."

"As long as they enter within one kilometer, it is the limit of what the awakened can see with the naked eye. Call me over directly."

"We must not allow the tiger-backed insects to get close to the bunker."

"They can destroy walls, tear apart the firing intermediate layers on outposts, and even leap straight into the interior."

Li Ran and Shen Jie put down the telescopes in their hands and nodded solemnly with worried expressions.

The second-level tiger-back worm is not something they can deal with.

Even powerful machine guns can hardly cause effective damage to them. Only large howitzers with a range of more than 100 mm or rockets can seriously injure them.

And this can be done in the outpost.

Only the Master Chief with the super bullet power.

The joy of victory did not last long...

With the appearance of the second-order tiger-spine worms, a heavy stone was placed on the hearts of the defenders, whether they were outposts, bunkers, or the front line of defense.

When everyone looked solemn and hardly smiled, Lin Feng slept until two in the afternoon.

During this period, I was not woken up once.

After he washed his face and woke up in the bathroom of the chariot, he learned from Chen Yanyan that the tiger spine worm seemed to have settled down two kilometers away.

There has been no other action.

Five hundred meters underground directly in front of the outpost, there was no sign of the red beetle swarm, and the wormhole was widened into a large cave to allow the tiger-backed worms to launch a surprise attack through the tunnel.

While eating the stir-fried military rations, Lin Feng frowned slightly, thinking about the strange behavior of the tiger-backed insect.

Could it be that it was just as he guessed, that it only showed up during the day to shock and intimidate the defenders within the defense line, making it difficult for humans to rest in peace, and then it could gain the upper hand at night?

But this is completely ineffective for me.

Because he has the level 20 flying tiger armor on him, Lin Feng is not at all afraid of a few cheap tiger-spine insects.

Judging from their size, they are about the same size as the ones that were chased last time.

Lin Feng's identification skills require a closer distance to scan out objects that are not too large.

So we can only estimate from the size comparison that these three tiger spine insects are probably in the early stage of the second stage. In this case, let's go and meet them.

Anyway, at this distance, after the Flying Tiger Armor turns on the flight mode, it can fly back and forth at a speed of 400 kilometers per hour in just seconds.

If there was still time, Lin Feng would even have the opportunity to use the Eye of Death in advance, aim at a lone tiger-back worm, and shoot it in the head.

190 points of basic damage, doubled by critical hit, it is a huge damage of 380 points.

The tiger-backed worm in the early stage of the second stage can't stand it at all.

After careful consideration, Lin Feng decided to take a risk before night fell.

After all, the late night will not only affect the soldier's combat effectiveness, but also hinder his pre-aiming, reducing his combat effectiveness and making it impossible to accurately shoot the tiger-spine worm in the head.

You can only use basic damage to suppress the opponent's attack.

Take advantage of the golden opportunity during the day to kill these ignorant tiger-backed worms, complete the upgrade of weapons and equipment and personal upgrades, and when night falls, the upgraded level 20 howitzer can easily solve the threat of tiger-backed worms.

Lin Feng told Chen Yanyan about his plan.

After a little worry, the other party agreed to cooperate with Lin Feng's plan.

Because this time we are fighting outdoors, we also have to guard against threats from the sky.

Lin Feng needs Chen Yanyan to control the lv19 flying wing tank and use the life radar to provide early warning.

The one that can directly threaten his safety in the wild is not the powerful tiger-backed insect, but the second-order flying insect that has never revealed its true form, the advanced version of the blue-winged insect...

The wind-winged insect is as powerful as a fighter jet!
According to the information sent by Ding Chenghai, the minimum speed of the wind-wing insect has reached 800 kilometers per hour, and even high-level wind-wing insects have the ability to fly at supersonic speeds!

Once they target Lin Feng, it will be difficult to escape unless they find shelter, such as by entering a wormhole.

Therefore, Lin Feng needed Chen Yanyan to give him an advance warning and notify him in time through the intercom so that Lin Feng could take shelter.

However, Ding Chenghai also mentioned that because the wind-wing insects are too fast, they only target high-altitude targets to curb air attacks from humans.

Low-altitude flying is generally not performed because of the risk of stalling and falling, as well as hitting obstacles.

After all, at that speed, even if it hits a bird, it would cause serious damage just like a human airplane.

But Lin Feng couldn't possibly gamble his life on this possibility, so he tried his best to make full preparations in advance.

When everything was ready, Lin Feng activated the full body form of the Flying Tiger Armor from the center of the outpost, then activated the Tiger Bug Power attribute, and finally turned on the flight mode.

A pair of blue-gray folded membranous wings slowly unfolded.

The extremely high frequency of the fanning stirred up the dust on the surface, and the powerful updraft made Lin Feng's feet fly into the air.

The next second, a black and yellow light flashed across the sky above the outpost and flew straight towards the front battlefield.

With a speed of over 100 meters per second, in just fifteen seconds, Lin Feng appeared in front of the cave where the tiger-back worm emerged.

It’s only five or six hundred meters away from the cave.

At this distance, Lin Feng was able to raise the muzzle of his gun and accurately lock onto the fragile head behind the tiger spine worm's huge jaws.

As Lin Feng descended and hid behind a raised mound of earth at a wormhole, the level 19 howitzer in his hand was ready to go.

Hold your breath, the Death Eye attribute is activated.

Previewing and locking...

In the cave below Lin Feng, countless red beetles and black-backed insects smelled the scent of humans and wanted to crawl out to attack the sudden prey.

But as the tiger insect's power was released, they were frightened and instantly retracted their heads and retreated deep into the cave.

Not long after, a tiger-backed worm, attracted by the flapping sound of the green-winged worm's wings, came out of the cave and half of its body appeared to check the situation.

"Tiger spine worm, lv23/29"

"HP 350, Vt 350, SPR 35"

"A mid-level unit of the Zerg, an advanced and upgraded version of the first-level soldier worm, the Black Spine Worm. It has strong physical functions and is extremely aggressive. The power of its pair of giant jaws ranges from tens to dozens of tons, and it can move at a speed of nearly 100 kilometers per hour. It is a powerful weapon for attacking the Zerg."

"Note: The giant jaw can be used as an orange quality material for fusion upgrades."

Lin Feng only glanced at its health value...

After that, without any hesitation, he locked onto the insect's eye, made a prompt decision, and pulled the trigger!
In an instant, a flash of fire appeared!
The shell left a straight tail flame and dissipated in the air.

But then, a loud explosion was heard from the entrance of the cave in the distance, and a flame several meters wide rose into the sky!

The next moment, a message flashed across Lin Feng's eyes:
"Successfully killed a lv23 second-order Zerg"

"LV19 Howitzer, the upgrade conditions have been met."

"Should we upgrade to a higher level?"

Lin Feng smiled, but before he could click to confirm the upgrade option, the joy on his face disappeared in an instant...

He stood up immediately and retreated instantly!
The next second, the entrance of the cave under Lin Feng suddenly collapsed!
A pair of bright yellow, ten-meter-long jaws opened,
Stick out from it!
