After Tang Bohu's teaching, Gu Xi finally understood how to hide his cultivation effortlessly, it turned out that as long as he felt the quanta around him and converged the energy that overflowed them, others would not be able to detect it.

This is for ordinary people, unless they reach the third state or even higher.

"Boy, seeing that I'm so careful, shouldn't you treat your handsomeness?"

Well, it turned out to be paid teaching.

"I only have these five left, alas, but you have to absorb the energy of so many crystals, are you not saturated?"

"Cut, you care about me~"

Tang Bohu walked to the door without looking back, but found that he couldn't do fingerprint recognition, so he had to look back at Gu Xi again.

As soon as he opened the door, Jin Ran hurriedly ran over and shouted, "Old Gu, come out quickly!" Zombie tide! The zombie tide is coming! ”

"?"

Through the window, Gu Xi saw that less than five hundred meters away from the periphery of the scientific research institute, there were lumps of black shadows, and he couldn't count how many mutants there were.

Gu Xi ran to the hall and took out more than thirty cold weapons for these people to choose from, and then said to Jin Ran: "Do you have any powerful thermal weapons in your weapons department?" ”

Jin Ran: "We have time there to study those!" But today I was in the security office on the first floor, and I saw a lot of thermal weapons, which should also come in handy! ”

Gu Xi: "Everyone! First floor! Let's go! ”

Although the building is extremely strong, if the corpse tide does not recede, the other victims will not be able to enter the building, so Gutsi decided to slaughter all the mutants.

Gu Xi has changed, and he didn't even notice it, he didn't care about himself, and he was dedicated to scientific research, but he cared about the safety of others.

Zhang Yinglong: "Brother Gu, I have been in the army before and am good at sniping, I want to snipe them on the second floor." ”

Wan Shu: "This long-handled broadsword is very good in my hand, I'll go to the front." ”

Zhang Weidong: "I just took these two assault rifles and carried a pack of bullets on my back, and now it is effortless for me to shoot with one hand." ”

……

Each of them said their thoughts, and Gu Xi hurriedly nodded in affirmation.

Seeing that the corpse tide was only more than two hundred meters away, Gu Xi felt that his blood seemed to be burning: "After a while, I will retreat to the building.

Brothers! Kill them all! We can survive better!! ”

The one who rushed to the front was really Jin Ran's kid, and I saw him holding a spear, and he rushed into the tide of corpses at once.

"Fuck! Refreshing! It's cool! What was previously only a fantasy has finally become a reality! Look at Lao Tzu beating you into a pulp! ”

Gu Xi shouted loudly: "Violent maniac, be careful! Have you forgotten the state of your loss of strength before the hospital? ”

After saying that, Gu Xi also began his own killing.

Today's big black is surprisingly light, and when the knife goes down, it seems that even the mutants have not reacted, and their heads have already left their bodies.

A hundred, five hundred, a thousand!

It's only been a little over an hour, and more than a thousand mutants have died.

"it!"

With Jin Ran's shout, Gu Xi saw a different mutant.

This mutant has huge arms, it should be mutated from a long-armed giant ape, and there is not a single mutated creature within fifty meters of him.

"Uncle Gu, come and save me! I can't hold it anymore. ”

At this moment, Jin Ran had been pressed low by the long-armed mutant, and his arm was also pulled wildly.

"Bang~"

Gu Xi slashed down, and a loud bang followed, but the long-arm mutant didn't seem to be harmed.

"Smack!"

It was Dalong's sniper rifle, but at this moment, Jin Ran's eyes widened.

“Fu*k！ What the hell is this? ”

The bullet had turned into a piece of iron, sticking to the center of the long-armed mutant's hall.

"Zhou Xianwei, you are fast, run over and say to Da Long, let him aim at his eyes as much as possible to see if he can shoot into his head from his eye sockets.

Violent maniac, I'll deal with it, you have to find a way to dig him out**! ”

Hyenas can survive on the African savannah, not only because they have a well-organized social system, but because they can always attack the enemy's weaknesses, so they also have a nickname - ** brother.

Almost all living creatures are weak in their raw weapons, and all Gu Xi has this guess.

"Smack!"

"Smack!"

"Smack!"

After receiving the order, Zhang Yinglong sniped three times in a row, and finally shot a bullet into the eye socket of the giant arm monster.

At this moment, Gu Xi jumped on top of the monster's head, and plunged Da Hei into the monster's other eye socket.

"Violent madness! Now is the time! ”

Hearing Gu Xi's roar, Jin Ran raised his spear and stabbed at the monster's **.

"It worked!"

But at this moment, the giant arm monster swung its arms irregularly as if it had gone crazy.

Gu Xi hurriedly said to Jin Ran: "This guy is different from ordinary mutant creatures, he can feel pain, but the weakness may still be the head. ”

Hearing this, Jin Ran had a flash of inspiration, pulled Gu Xi to the side and said, "Is the lava meteor hammer inside your ring?" ”

Gu Xi didn't understand what he meant, but he still nodded.

Jin Ran: "Wait a while, I'll use my ability to build a glass ladder for you, you stand on top of that monster's head, and then take out the lava in the air, 5,300 catties, I don't believe it can't be killed!" ”

Gu Xi suddenly brightened, worthy of being a little clever ghost in the weapon research and development team, and his head was really bright.

Gu Xi stepped on the glass stairs step by step, but this scene was seen by others but had a different feeling, this Gu Xi, can he still fly?

"Find a way to trap it, I didn't aim at it."

When Jin Ran heard this, he pointed to the surroundings of the giant arm monster, and four transparent barriers appeared, trapping it inside and not moving.

But at this moment, the monster slammed hard, and one of the barriers shattered.

"Poof!"

A mouthful of old blood spurted out, making Jin Ran look much more depressed.

Gu Xi: "Daikin! ”

"Don't me! Come on! ”

As soon as he finished speaking, Jin Ran's legs could no longer support the weight of his body, and he knelt on the ground fiercely.

"Boom~"

The lava meteor hammer smashed down, and as soon as it came into contact with the head of the giant arm monster, the explosion protruded, and the heat wave overturned Gu Xi and Jin Ran and threw them into the distance.

——————

Waking up again, Gutsy found himself lying in a room on the top floor of the building.

"Daikin!"

He sat up as soon as he got out, put on his slippers and went out.

As soon as he went out, Zhou Lingshen came over and said, "Brother Jin is fine, Dahua asked me to tell you, he still needs to sleep for a while." ”

Gu Xi nodded, "What about the others?" ”

Zhou Lingshen: "The others are fine, as soon as the giant arm monster was killed by you, those zombies retreated." ”

"I don't know if the monster's head was smashed or blown up, it cracked, and all the brains became sparse, and we didn't take any time to dispose of this corpse."

"The others, together with the explosion, killed a total of 2,120 zombies, and obtained a total of 260 blue crystals, 27 green crystals, and 1 white crystal."

"After they collected it, they all paid it on their own, saying that they would distribute it when you woke up."
