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

Chapter 104 Upgrade! Level 20 Armor-piercing Cannon!
As Lin Feng activated the flight mode of the lv20 Flying Tiger Armor, he flew backwards relying on the inertia of backward movement.

The once hidden mound of earth at the entrance of the wormhole collapsed in an instant, revealing a loose deep pit.

Just as the mud and sand were constantly flowing due to the high-frequency tremors, a ten-meter-long giant jaw suddenly broke out of the ground from the position where Lin Feng was previously, like a thorn!

With a click, it closes and cuts!

The sharp barb at the tip of the giant jaw was only a few centimeters away from Lin Feng's toes after he jumped into the air.

Fortunately, he reacted quickly. If he had been a few microseconds slower, he would have lost both legs and suffered serious fractures.

Previously, due to the activation of the Eye of Death attribute, Lin Feng entered a state of full concentration, holding his breath, especially at the moment of pulling the trigger at the last moment, his attention was ignored for changes in the soles of his feet.

A large number of red beetles used their chelicerae to insert into the cave wall, and then began to shake in unison.

It was exactly the same situation that Lin Feng had encountered in the Haicheng dormitory building.

At that time, the red beetle swarm knocked on the ground and walls together, calling for their kind to come...

Their consistent behavior at this moment is to use rapid vibrations with synchronized frequencies to destroy the stability of the soil structure, turning the soil on the cave wall into quicksand, allowing nearby tiger-backed worms to quickly swim through the cave.

When the tremor reached Lin Feng, it was at the last moment that he discovered the change under his feet in time, and he had no time to upgrade the lv19 howitzer that had completed the kill.
Lin Feng retreated several steps and flew into the air.

The tiger-backed worm stretched out a pair of huge jaws, but found that it could not bite the target, so it slapped heavily backwards, trying to injure Lin Feng.

It has to be said that as an upgraded version of the black-backed worm, the tiger-spine worm has not only achieved a qualitative leap in its physical attributes, but its IQ has also been improved, which is fully worthy of the dozens of points of mental value.

If Lin Feng had not acquired the ability to fly, it would not have been so easy to avoid this crisis.

As he took off into the air, the level 19 howitzer in his hand was already aimed at the quicksand cave below!
The shells were fired like flowing water, madly!

Amid a series of explosions, the tiger-backed worm quickly hid deep in the tunnel, but the red beetles that helped it build the quicksand river were not so lucky.

The howitzer has a damage of up to 190 points, and the shock wave generated by the explosion can kill them directly.

Then the tremors stopped and the fluid-like soil gradually stabilized.

Even though the tiger-backed worms lost their breakthrough point for attack, Lin Feng still pulled the trigger until he blew up a more than ten-meter-deep pit in the concave pit under his feet, and then stopped the bombing.

Fortunately, the tiger-backed worm ran fast, and it was protected by the soil with its hardest jaws facing upwards, so Lin Feng only inflicted nearly a hundred points of damage after firing dozens of shots.

To the tiger-backed worm, it was not even a serious injury.

It's a pity that it was let go.

Lin Feng groaned and spat out yellow phlegm on the ground.

It was filled with mud and sand, the flying dust that he had inhaled during the previous retreat and shooting.

After using telepathy to confirm that there were no tiger-backed worms nearby, Lin Feng decided not to stay any longer and gave up the idea of ​​going to the distant cave where the tiger-backed worms died to check the bodies.

Qin Hu’s experience is still vivid in my mind.

Even though Lin Feng was protected by the Flying Tiger Armor, he did not want to take the risk of fighting with the Zerg for corpses in the cave.

If he were to besiege several tiger-backed insects, his level 19 howitzer alone would not be able to handle it.

With a flash of light, within fifteen seconds, Lin Feng maintained an altitude of fifty or sixty meters and flew back to the outpost fortress.

At this moment, many of the new recruits, as well as Li Ran and others, were stunned.

With Shen Jie's reminder, they already understood that the humanoid creature wearing black and yellow flying armor who broke into the Zerg's hinterland was none other than their Chief Sergeant, Lin Feng.

When the familiar explosion sounded, Li Ran and others who were observing through telescopes cheered for the tiger-spine worm being hit to death, but also clenched their fists for Lin Feng who successfully avoided the Zerg counterattack at the critical moment.

At this moment, the Master Chief returned victoriously, flapping his membrane wings and landing steadily next to the tank in the center of the outpost.

Li Ran, Shen Jie and others came over, and after the smoke and dust cleared, they saw the facial armor unfolded in the black and yellow flying armor, revealing a familiar face, and they were immediately overjoyed.

Ninety percent of the outpost bunker's combat effectiveness comes from Lin Feng himself, and the stronger Lin Feng is, the greater their chances of successfully defending.

Whether it is demonstrating its unique flying ability or its means of fighting against or even killing tiger-spine worms... it can greatly alleviate the deterrent pressure that the second-level Zerg brings to the defenders.

Morale is an important thing.

Especially in long-term battles, the loss of morale means that the team's combat effectiveness will plummet.

This psychological factor can sometimes even determine the outcome of a war.

Lin Feng's achievement of going deep into the Zerg's hinterland and not only killing a tiger-spine worm but also escaping unscathed will undoubtedly greatly encourage the soldiers at the outpost and they will no longer be afraid of the more difficult battle tonight.

Because they are led by the sergeant.

Even if the tiger-backed worm attacks, there is nothing to fear.

Facing the gazes of Shen Jie and the others, as well as the expectant looks of many soldiers on the shooting floor on the wall, Lin Feng spoke calmly:
"I have successfully killed a tiger spine worm and am about to enter the second stage of awakening. Disperse, I need to have a good rest and complete this awakening before night falls."

Hearing the Chief's personal confirmation, everyone cheered!
The awakeners of the second stage are powerful beings that are one in a million...

Not only will the superpowers achieve a qualitative leap, but the combat power will also be greatly enhanced.

For example, Major Cheng, who returned unexpectedly, was promoted three levels directly because he successfully advanced to the second level of awakening, becoming the only awakener with the rank of colonel.

But he is just an awakened one with enhanced physique.

And at this moment, Sergeant Lin in the outpost is the famous Super Bullet Awakener!
Once the ability is further improved, it is estimated that it will be possible to kill tiger spine insects remotely and directly bomb the insect swarm army. As Lin Feng waved his hand, he walked into the chariot under the attention and expectation of everyone. The excitement filled the outpost and did not dissipate for a long time.

Chen Yanyan stood up from the driver's seat and saw Lin Feng take off his full body armor, revealing his true form. She breathed a sigh of relief and smiled as she stepped forward to help Lin Feng take off his short-sleeved pants that were already soaked with sweat.

Continuous flight would cause the Flying Tiger Armor to overheat, and the sudden increase in heart rate and adrenaline due to the previous life-and-death crisis made Lin Feng sweat all over.

Ease and invincibility are shown to outsiders.

Only Lin Feng himself knows the true danger.

"Didn't you find any traces of flying insects?"

Lin Feng took the dry towel handed to him by Chen Yanyan, wiped the sweat from his forehead, and asked.

Chen Yanyan shook her head:

"No wind-wing insects were detected, but there were a few green-wing insects. One was hiding in the distance and watching, and never approached."

"They will probably go back and tip off the Zerg Queen. She will definitely be on guard. Next time we go out of the city to fight, it won't be so easy..."

Lin Feng nodded. The flying mode of the Flying Tiger Armor could not be hidden for too long. He had intended to use it to exchange for equipment upgrades from the very beginning.

Now that this goal has been successfully achieved, Lin Feng, who has been upgraded to level 20, will have corresponding solutions even when facing the attacks of wind-wing insects.

Moreover, the flying mode is only the variant form of the Flying Tiger Armor, and one of them is an auxiliary form. The remaining two types, whether it is absolute defense or explosive scale armor, can effectively resist wind-wing insects.

"Then you continue to monitor. I need some time to wake up and cannot be disturbed."

As he spoke, Lin Feng frowned slightly, his eyes deep:

"If during this period, the Zerg launched a general attack and several tiger-spine worms were preparing to attack the city, you could just press the detonator of the explosives on the road and drive away from here."

"As for the others, take them if you can."

Chen Yanyan took a deep breath and then nodded solemnly.

As the awakening unfolds, Lin Feng will inevitably lose his combat effectiveness for a period of time, and this will also be the most vulnerable and dangerous moment for the outpost.

As Lin Feng's most trusted person, he must make a decisive decision when necessary to abandon some of the garrison and protect Lin Feng from escaping from the outpost.

Seeing the detonator Lin Feng placed on the table, Chen Yanyan watched him walk into the bedroom and then returned to her post.

Confirm that the tiger spine beetle has not come and take revenge.

In the bedroom, Lin Feng started the upgrade of the lv19 howitzer, then walked into the bathroom to wash off the sweat on his body, and at the same time rinsed the arm guard that was covered with dust and mud.

After washing and walking out of the bathroom, he ate some compressed biscuits, chocolate and other high-calorie foods. When he felt full, Lin Feng lay on the bed, quietly waiting for the completion of the howitzer's upgrade.

It's only half past one now, and there are still about five hours before dark, so there's still enough time.

What I told Chen Yanyan before was only the worst possible scenario with a very small probability.

If the Queen Mother had any brains, she would not launch an attack during the day when she knew that the sentry had the ability to kill second-level Zergs.

The best decision is to retreat and make plans later.

Soon, after an hour of upgrading, the lv19 howitzer successfully entered the orange quality.

"Armor-piercing cannon lv20/29, orange quality"

"Damage 250, effective range 10 kilometers, remaining bullets 6000/6000"

"Additional attributes: bullet recovery 1/s, space magazine 6000 spare bullets, death eye 0/50, fire coverage damage 50+50/s, coverage area square meters"

「Added additional attribute: Bullet Time」

"Evaluation: This is an armor-piercing cannon that can penetrate a hundred millimeters of defense. Its powerful penetration makes it difficult to maintain its narrow body, but the changing form can better exert its long-range combat power. The enhanced shell can penetrate ten meters deep soil through multiple energy additions. Hitting the target can cause internal explosion damage, posing a serious threat to targets with extremely high armor values."

Looking at the level 20 armor-piercing cannon in his hand that flashed with orange light and transformed from a pistol to a rifle, Lin Feng could already feel its weight increasing exponentially.

Don't be fooled by its appearance at the moment, it looks like only a dozen pounds, its actual weight is up to hundreds of kilograms. But in the hands of a first-level perfect awakener who can exert several tons of force with a swing of his arms, a gun weighing a hundred kilograms is no different from the wooden stick it once was.

Lin Feng can still aim the gun with one hand at will, and after the upgrade it is also equipped with a matching zoom lens, which can be switched from 4x to 8x at will.

What’s more important is that this scope can superimpose Lin Feng’s eagle eye vision as an awakened person.

In other words, its actual observation and aiming distance is within eight kilometers.

Like small rockets and anti-tank missiles, Lin Feng's actual combat distance was increased several times.

But there seems to be no night vision mode...

There will still be a big discount at night.

But this time the upgrade directly increased the basic damage by 60, which made Lin Feng very excited.

With 250 points of basic damage and the Eye of Death, the headshot damage can be doubled. Even a level 25 tiger spine worm will die on the spot.

As for the ammunition, one thousand were added, but there was no actual change in other aspects.

Lin Feng continued to look down and saw the newly added additional attributes that he had been missing:
Bullet time...
