How so!?

"Someone must have arrived at the lab before us," Yan Lie was sure of the corpses on the ground outside the door. Pen & Fun & Pavilion www.biquge.info

"Could it be other plane merchants," Song Yao asked.

"Chances are, you see, some of these zombies have been pierced through their bodies, some are charred and frozen, and it seems that at least two people have already entered," Yan Lie analyzed.

I don't know who will complete this task in the end, but Song Yao only hopes that she can get out of the way!

The zombies on the basement floor have been killed, safe!

The zombies on the second basement floor have been killed, safe!

The zombies on the third floor underground have been killed, safe!

Four basement floors?

"There are zombies, pay attention!" Hearing Yan Lie's reminder, Song Yao immediately raised the iron rod in his hand, the front end of the iron rod was already pointed after Yan Lie's improvement, and it was easier to kill zombies.

The zombie in front of him was ragged and moved faster than ordinary zombies, and it seemed to be a T2 zombie.

Zombie levels can be divided into T1, T2, T3, T4, T5 and so on.

Now the level of Yan Lie can already deal with a T5 zombie alone, so I saw a flash of white light, and the head of that T2 fell off.

Along the way, it is basically Yan Lie who kills zombies, Song Yao will only help cut a few zombies when there are too many zombies, not that she doesn't want to help, but she is afraid that she will help more and more, her biggest function now is defense, I don't know why, as long as you kill a zombie, the system will reward a crystal nucleus, the level of the crystal nucleus is determined by the zombie level, is it like what is written in the novel, this crystal nucleus is grown out of the zombie's brain?

It has been proven that this is indeed the case.

As soon as he finished killing a t2, Song Yao found that there were a lot of zombies coming out of the passage inside, most of them were t3, and even t4 had a lot, and found the seriousness of the matter, the two of them were waiting for it, Yan Lie's hand kept sending out ice blades, and Song Yao was protecting him every step of the way, with Song Yao, Yan Lie didn't worry about getting hurt, so the zombies killed extremely quickly.

In the end, a few T4 couldn't help but rush towards Song Yao and Yan Lie, once, twice, suddenly, Song Yao found that his protector Yu Pei seemed to be a little broken, and hurriedly signaled Yan Lie to fight quickly.

Half an hour later, looking at the corpses all over the ground, Song Yao breathed a sigh of relief.

One of the doors of the laboratory next to "Ka" opened, and two men walked out, both about 180 tall, the one on the left was very handsome, and the one on the right was a little thin, no matter how they looked at it, they didn't look like the kind of people who were capable of killing several layers of zombies, but the truth was always unexpected.

According to Song Yao's estimation, the two of them should be plane merchants, and they should have been recovering their strength just now, otherwise they made such a big move, how could the two of them let the crystal nucleus be taken away by them.

"Hello, I'm Surong, he's Cora, I'm sure you're here for that thing." The man on the left is also Su Rongdao.

After receiving an affirmative answer, he continued: "Since we are both plane merchants, then, for the common good, the common goal, let's cooperate."

Cooperation is good, but once we encounter the problem of distribution, it is very easy to have contradictions, leading to contradictions, how to solve this problem?

Just as Song Yao was thinking about it, Yan Lie had already made a decision.

"It's okay to cooperate, but in the end, the root cause of the virus is eliminated and the person who contributes the most can give priority to the selection of the spoils, of course, this is when there is loot and it can be distributed, and the others are distributed according to work." Yan Lie suggested.

After some discussion, all four finally approved the plan.

Although it was only a few minutes, several people completed the assigned task very quickly, and the two men who suddenly appeared made Song Yao very vigilant at first, but the conversation of just a few words made Song Yao intuitively feel that the two were not bad people, and the other two felt the same for Yan Lie and Song Yao, so there was the above scene.

On the fifth floor underground, Song Yao and others are struggling to kill zombies, although there are fewer zombies on this floor than in the previous layers, but zombies are not much more expensive, most of the dozens of zombies are T5 zombies, and a few are T4 zombies.

Song Yao and Cora are responsible for pulling hatred, as long as the zombies gather in the direction of Surong and Yanlie, they will use sticks or laser swords to divert their attention, so that Surong and Yanlie can do their best to deal with the zombies.

Originally, Yan Lie could only barely deal with a T5 zombie by himself, but Cora inadvertently said that he saw that the abilities of this world could use the crystal nucleus in the zombie's brain to cultivate, so Song Yao asked Yan Lie to give it a try, and it turned out that Song Yao's conjecture was right, Yan Lie could cultivate by absorbing the energy in the crystal nucleus.

Because Yan Lie had to absorb the energy of the crystal nucleus, they postponed it for a day.

One day is enough time to make a person stronger, and the flame that has absorbed countless crystal nuclei is already comfortable dealing with T5 zombies, and the handsome appearance is beyond Song Yao's expectations, and he is very strong, it turns out that he and Kora, one was born on a planet where Xiuzhen is prevalent, and the other is born on a planet with advanced technology, and the strength of the two is not bad, but Kora's planet pays attention to the development of science and technology, and does not pay much attention to physical fitness, so he can only pull hatred with Song Yao.

One zombie after another was wiped out, and the dawn of victory seemed to be close at hand, however, imagination is always beautiful, and now it is always cruel, just when Song Yao and the others thought that victory was in sight, the appearance of a t6 broke their dreams.

"It's T6!!" Song Yao exclaimed.

I saw a huge zombie coming from the depths of the aisle, its size, and its clean face different from other levels of zombies, all proved that this was a T6, if they were still in their heyday, maybe they could fight with it, but now after a fierce battle, there is not much strength left, and when they encounter this T6, they will probably only be killed.

"Oh no, get back!!" Yan Lie pulled Song Yao up and turned around and ran.

Su Rong and Cora ran away when they saw Yan Lie turn around, knowing that they were by no means T6's opponent now, and they also ran back with Yan Lie.

But T6 couldn't let them go, only to see T6 quickly chase after them where they had fled, and soon it caught up with Cora who was running behind.

A ball of flame erupted, and in an instant, Cora was surrounded by flames.

"Ahh

The flames burned through his shield, and Cora became a burning man, and Surong, who ran in front, found that Cora was in danger, and hurriedly summoned a large ball of water.

The fire on Kora's body was extinguished by Surong, but the person was burned indistinctly, and Surong hit T6 with another wind blade, and T6 could only dodge to the side in order to dodge.

"I have access to a state-of-the-art lab! The lab is so tight that there's no way T6 can break it in, but I'll need time! Yan Lie said as he ran.

When Su Rong and Cora heard him, they both said that they could delay T6 for a while, but the time was only ten seconds, and after ten seconds, if Yan Lie couldn't open the door of the laboratory, they would all die.

Seeing that T6 was about to catch up with them, Su Rong and Cora hurriedly resorted to all means, trying to drag T6, only to see a wind blade rushing towards T6, T6 couldn't dodge, and several scars appeared on his body, before it could react, another laser gun pierced its body, and then Su Rong and Cora cast a five-element spell, and one used high-tech products to catch T6 off guard.

Of course, in fact, this is only their last counterattack, which can only injure T6 and delay time, but not kill it.

The underground laboratory wants to enter it quite strictly, and the corresponding fingerprints are required to enter the laboratory, originally Yan Lie had the right to enter several of the laboratories, but that was before, and now he can only rely on the fingerprints of high-level personnel cut off on the road to enter it.

"Didi, fingerprint verification successful"

In just a few words, Song Yao felt that it was like a fairy music.

The door to the "Click" lab opened.

Yan Lie entered it first, and after making sure that it was okay, he hurriedly let Song Yao and them go in as well, looking at Su Rong and Cora who were fighting, Song Yao motioned for them to come in quickly.

Su Rong and Cora fought and retreated, but the worst thing was that the T6 also slowly approached the laboratory!!
