Gu Chen's eyes widened, his face was incredulous and uncertain.

He did have greed just now, and wanted to be greedy for Yang Cheng's credit.

However, he hadn't even figured out whether he wanted to coerce and lure, or just kill Yang Cheng here without doing anything.

But he never expected that at this time, Yang Cheng would suddenly make a move and kill his 'chief'!

"Yang Cheng! Are you crazy!? ”

Gu Chen snorted.

Yang Cheng showed a cold smile at Gu Chen, and blood erupted, his body was like a cannonball, and he blasted straight at the soldier of the other Guardian Corps!

A powerful electric current appeared around the soldier of the Guardian Legion, turning into a power grid around him.

But Yang Cheng went straight through the power grid, and in the soldier's shocked gaze, he smashed his heart with a punch!

The corpse with a big hole in his chest fell head-on, Gu Chen raised his hand in anger, and dozens of small and delicate grenades smashed directly at Yang Cheng.

Those grenades unexpectedly began to move in mid-air, like a big net, directly blocking all the spaces for Yang Cheng to dodge.

The next moment, the grenades exploded, and there were laser rays scattered among them.

As the smoke and dust dissipated, Gu Chen's face was shocked.

Yang Cheng's body was shining with gold, and those grenades couldn't hurt Yang Cheng in the slightest.

"Yang Cheng! What exactly do you want to do!?

Fellows of the Killer Guardian Corps, you wait to be court-martialed! ”

A strange smile appeared on the corner of Yang Cheng's mouth: "It's not like I haven't killed the waste of the Guardian Corps.

Gu Chen, this time you came up to find death by yourself, and you can't blame me. ”

Hearing Yang Cheng shout his name, Gu Chen's Tong Kong suddenly shrank.

From his appearance to the present, he has never said his name to Yang Cheng, how did Yang Cheng know?

He suddenly thought of something, and exclaimed, "You killed Su Jie!?" ”

He also knew about Su Jie's death, but Gu Chen didn't think about Yang Cheng.

It's not Gu Chen's carelessness, but inertial thinking.

How dare those Qiu Ba of the Explorer Corps touch the people of his Guardian Corps?

Borrow ten of them, and they will not dare!

But unfortunately, Yang Cheng is not among common sense.

"If you want to blame Su Jie, that guy dragged you into this matter.

When you're dead, go down and trouble him!" ”

The chilling wind and sharp sword light were already close in front of Gu Chen, who was already close to him almost instantly.

Gu Chen had seen Yang Cheng's powerful physical body and terrifying melee power.

Therefore, his figure retreated sharply, and the flames and thunder in his hands were filled, turning into a huge net to envelop Yang Cheng in it!

Third-Order Genetic Elixir: Spirit of Flame and Thunder!

Gu Chen is different from Su Jie, who was stuffed into the Guardian Corps purely by virtue of his relationship.

Although he was also from the fourth tier of the wealthy district, he joined the Guardian Corps since he was a child, and seized every opportunity to be promoted.

So at about the same age, Su Jie is just a major staff officer, but Gu Chen is already a colonel.

And he has also performed a lot of escort missions, and he has a lot of practical experience.

It's just a pity that his little practical experience is not worth mentioning compared to Yang Cheng!

The sword tore through the flame and thunder net, and the powerful Gang Qi swept and pulled Gu Chen, making it impossible for him to retreat.

The thunder light turned into a shield and was horizontal in front of him, but it was slashed by Yang Cheng.

At the critical moment, a palm-sized piece of mechanical armor on Gu Chen's chest instantly stretched out in front of him, and finally resisted Yang Cheng's knife.

But the armor was instantly dented and torn, and Gu Chen spurted out a mouthful of blood and flew out.

"Don't kill me! Tower coins, genetic potions, as long as you want, I can give them to you! ”

After seeing Yang Cheng's true strength, Gu Chen didn't even have the heart to resist, and began to beg for mercy.

Yang Cheng shook his head lightly and said: "To be honest, it's really boring to do it with you, all of them are soft bones, and there is no sense of accomplishment when you kill them." ”

Those mutants in the outside world will at least fight to the death in despair, but these guys from the Guardian Corps don't even have the courage to fight, it's really boring.

"Tell me, how many tower coins are you going to buy for your own life?"

Gu Chen gritted his teeth and said, "One hundred thousand!" I have 100,000 Tower Coins in the Tower Residence, all in a black card, which is my accumulation over the years. ”

"So you don't have too many Tower Coins on you?"

Gu Chen nodded helplessly.

He is cautious, all the black money is stored with a black card, and the permanent residence card he carries with him is only his salary, which is only a few thousand tower coins.

Yang Cheng shook his head and raised the Imperial Forest Saber: "Remember it in the next life, remember to take the money with you!" ”

Seeing that Yang Cheng was about to make a move, Gu Chen's eyes turned red, the thunder light around his body shone, and the flames had completely surged into the veins, and the whole person was ignited with raging flames.

Yang Cheng waved his hand, and the demon immortal body that had not been used for a long time conjured out, directly winding Gu Chen's body.

Gu Chen completely struck out the genetic power, but his physical body could not support such a powerful thunder and fire power, and his physical body had already begun to collapse.

He frantically broke free, and finally tore Chang Cuiyun's demon immortal body apart, but there was a lot of qi all around, and a large area of yellow sand swept up to trap Gu Chen in it.

Yang Cheng threw the other two members of the Guardian Corps into it, and Gu Chen's voice gradually changed from hatred to a terrible roar and wail.

His genes were completely out of control, and the thunder flames around him boiled, burning the bodies of his entire person and the other two Guardian Corps directly into ashes.

The yellow sand dissipated with a wave of his hand, and there was not even a trace on the ground.

Yang Cheng nodded with satisfaction.

If there were more opponents who destroyed their own corpses, he would save effort.

Glancing at the map, Yang Cheng was not ready to return to the team immediately, but was ready to go to the Suiren Shelter first and hand over the things to Professor Sun.

It was only a little more than a hundred kilometers away from the canyon of the Suiren Shelter, and not far away, Yang Cheng also found a chariot left by Jaguil's men, which should have been left behind after being chased here by Gu Chen and the others and killed.

Two hours of driving is enough to get to the place, and the chaos is not over yet, so the time requirements for returning to the team are not so strict.

At the door of the Suiren Shelter, Uncle Chen saw Yang Cheng coming, and immediately shouted in surprise: "Mr. Yang, are you here?" ”

Most of the residents of the Suiren Vault are actually very honest.

Ren Tianxing and Professor Sun protected them too well, so apart from normal battles, they rarely fought alone to intrigue with outside forces.

In their opinion, since the leader and Professor Sun both recognized Yang Cheng, Yang Chengcheng was their friend.

Not to mention that this friend is also very generous and invited them to eat a meal of meat.

"Uncle Chen, please take me to meet the leader and Professor Sun."

Uncle Chen hurriedly opened the door and led Yang Cheng into the shelter.

After chatting a few words on the way, Yang Cheng realized that the uncle in front of him was Chen Xiangdong, and he was the father of Chen Wu, the captain of the third squad of the shelter.

There are a total of ten squads in the entire Suiren Shelter, each of which ranges in number from a few dozen to hundreds of people, and the combined number of men and women who are capable of fighting is more than a thousand, and it can almost be said that all the people are soldiers.

When Ren Tianxing and Professor Sun heard that Yang Cheng was coming, they hurriedly came forward to greet him in person.

"Leader Ren, Professor Sun, I got everything you wanted."

Yang Cheng entered Professor Sun's laboratory and took out all kinds of experimental equipment, which were almost eighty percent new, as well as some of the materials that Yin Lin had obtained.

Professor Sun flipped through the materials, and his heart was slightly excited.

Yin Lin's level in the Tower Laboratory is actually not high, and the information he got is not too top-secret.

However, for a scientific research talent of Professor Sun's level, what he lacks most in the outside world is scientific research materials, information, experimental data, etc. of various mutant materials.

In the past, Professor Sun had to calculate these manually, but now that he has ready-made information, he will save a lot of time.

And these devices are also a little different from what Professor Sun thought.

Originally, he thought that almost all of the equipment that Yang Cheng could get was some scrapped things, and he needed to repair it before using it.

Who would have thought that these devices are almost all new, and they do not affect the use at all.

There are also those mutated creatures and plants that are also extremely rich in materials.

Because some mutant creatures are thousands of miles away from the Suiren Shelter, the Vault simply does not have the strength to hunt mutated creatures that far, so Professor Sun has always heard of these things, but he has never even seen them.

"These things are enough for Professor Sun to make a fourth-order potion?"

Professor Sun nodded excitedly and said, "Enough!" Totally enough!

Even today, you can create a fourth-order potion! ”

The difficulty of making a fourth-order potion is not time, as long as the materials and experimental procedures are correct, it can be done in a few hours.

Yang Cheng suddenly became interested: "What kind of potions can be made?" By the way, I have one more thing here. ”

As he spoke, Yang Cheng handed over the ghost dragon crystal he had obtained from the Dead Sea ghost whale to Professor Sun.

Professor Sun was surprised: "The power core of the Dead Sea ghost whale? The people of the Vault had found its traces in the Dead Waiwai, but they didn't expect it to be killed by Mr. Yang.

This is a good thing, in a fourth-order potion that I deduced earlier, there is just a lack of a strong core material like the Ghost Dragon Crystal. ”

As he spoke, Professor Sun took out a stack of thick notes, flipped through them, and said, "With these instruments and materials, I am sure that there are many fourth-order elixirs to be made, which need to be matched with the most suitable elixir according to Mr. Yang's own basic attributes and the strength you master, I don't know if Mr. Yang is willing to tell me this?" ”

For most people, it is a very taboo thing to let the other party clearly know their various strengths.

After all, that's the equivalent of giving out all your hole cards.

But Professor Sun's behavior is equivalent to tailoring a genetic medicine for Yang Cheng, so he must know these things before he can do it.
