After the two parties discussed, they set out to go to the laboratory.

"I was dizzy just now, stay and rest, and the rest of me will come with me."

Yin Yunchen gave the order and took the team members and followed the other party's people downstairs.

When they reached the first floor, only the opposing team leader and his deputy went down together.

Yin Yunchen also saw the reason, and looked at a few people in the team who felt unwell.

"A few of you stay on the first floor to pick up."

Several people knew in their hearts that it would be a lag to follow, so they consciously stayed.

The further down you go, the clearer the zombie's roar becomes.

The lab is a hidden entrance to the underground parking lot, and the group continues downstairs.

The corridor is long, deep underground, passing through ten gates on the way.

Yin Yunchen counted, went down every fifty steps, passed through a door, and walked forward for more than two hundred meters.

"This is it."

The leader looked at the door in front of him and said.

Yin Yunchen looked at the ordinary glass door and thought back to the direction of going downstairs.

In their direction, two kilometers east of the mall, the lab was under an artificial lake.

Five hundred stairs is twenty-five floors.

A laboratory built dozens of meters under an artificial lake and surrounded by high-tech industries is really curious.

There were a few more people in the team who felt uncomfortable, but they all got here, so they could only hold on for a while.

"Captain Yin."

The team leader stopped Yin Yunchen.

"Please."

He looked at the slightly uncomfortable group of people in the back.

"I don't think they'd go in again. This is the edge of the zombie's range, and beyond that, the zombie will be able to attack them.

The few teammates I left behind were attacked. ”

But a few of the team members were in a hurry, they didn't want to be left behind.

"Captain!"

Yin Jin tugged at Yin Yunchen's sleeve.

Yin Yunchen naturally understood what Yin Jin meant, nodded to the team leader, and gestured to the few people who were uncomfortable.

"You guys stay, stay safe."

A few people couldn't, so they had to listen.

"Yes, Captain."

At this time, only Yin Yunchen, Yin Jin, Zhang Zhen's father and son, and Uncle Li, as well as a team leader, followed the other two into the laboratory together.

The laboratory has its own water and electricity system, which is enough to support it for up to a year in closed mode.

That's what the team leader said.

When they entered the two gates, they saw the door of the real laboratory.

This is a heavy tempered glass door, which requires correct fingerprints, badges and passwords to enter.

From the outside of the door, you can see that it is a mess inside, with many blood stains.

"There's only that one zombie in here right now, so you don't have to be too nervous."

Zhang Yang, who had just grasped the weapon in his hand, let go of his heart a little after hearing the words of the team leader.

Yin Jin walked all the way, observed all the way, and they entered a control room-like place, and they could see the situation in all the rooms from the surveillance.

"You see, this is it."

The zombie sensed that someone was entering his range, and the roar changed in frequency.

Zhang Yang, who had the weakest spiritual power here, suddenly turned pale, and spat out blood.

The crowd became vigilant.

Zhang Zhen hurriedly helped Zhang Yang.

"Zhang Yang, how are you?"

Zhang Yang frowned, just now he only felt that his heart was rippling, and his head was a little confused.

"My chest is a little stuffy, it's not very comfortable, my head is a little dizzy, it's like drinking too much, it's very uncomfortable."

"He must have been attacked by that zombie."

The team leader voiced his guess.

"It's just that my teammates died directly after being attacked before, or if they were dizzy, nauseous, unconscious, and vomiting blood, I don't know what's going on."

The group frowned, Yin Jin thought about it, and suddenly thought of something, yes, this zombie must be....

"Is that zombie going to level up?"

Although she asked again, she was very sure in her heart.

At present, the base of the team leader, although he has a certain understanding and research on the zombie level.

But I've never seen a second-level zombie, so naturally I don't know what special characteristics there are.

Several people listened to Yin Jin's speculation, and their hearts sank.

Originally, they didn't have much confidence in dealing with first-level zombies, but if they were second-level, it wouldn't be .........

Only Yin Jin thinks that he can give it a try.

Spiritual zombies can be regarded as the strongest in the same level, and they can also be regarded as the weakest existence in the same level.

If it's just a spiritual department, then the physical reinforcement is weaker.

She and Yin Yunchen are both level 1, although the team leader has not used the ability, but if he can get here, even if he is a beginner, it is not far from promotion.

At least all of them have better mental strength than ordinary people.

Yin Yunchen looked at Yin Jin, although he was a little worried, but he also had the same thoughts as Yin Jin.

Since the end of the world, although he feels that his sister still needs protection, it is out of the care of his relatives, not because he thinks that Yin Jin is weak.

"We act as soon as possible. Go back to the door. ”

"Captain, I'm fine."

Zhang Zhen looked at his son, thought for a while, and then said.

"Team Yin, let him follow first, and then go if you can't hold on for a while."

Yin Yunchen nodded, and then everyone began to discuss the specific plan.
