Ten minutes later, a group of five people came to the metal door that was destroyed by Lu Ming last time.

The metal door of the institute was not repaired, but simply blocked with a few iron plates, which did not look strong, and the iron plates were rusty with some small letters, which looked like they had been picked up from some factory.

Yan Zhengfeng took the lead and walked to the iron-plated door that looked very unstable, his brows furrowed slightly.

It was completely different from the last time he came, there were no guards inside the door, and it was clear through the scene behind the interval before the iron plate door.

In fact, it is an exaggerated metaphor to say that it is a door, if Yan Zhengfeng wants to, he can pass it through the interval between the iron plates at any time, this kind of iron plates, it is estimated that even the zombies without brains can stop them.

The scene in front of him made him a little suspicious, but Li Ying still saw that someone was entering and exiting the entrance of the institute during the day today, but if he didn't completely evacuate, why didn't he even have a person guarding the door?

The doors are closed, and the pipes of the research institute look very strange.

Yan Zhengfeng muttered a little, did the people from the research institute get the news and escaped from the other entrance.

"Let's go in and have a look." Li Ying came to Yan Zhengfeng's side, and she frowned when she saw this scene, and the situation in front of her made her a little incomprehensible.

Suddenly, Yan Zhengfeng grabbed Li Ying, who wanted to enter, stared at the iron door in front of him, squatted down, reached out and dug lightly on the ground a few times, revealing a swarthy object.

Yan Zhengfeng stood up and said to Li Ying: "They know that we are coming, and they have already made preparations, I am afraid that they have already set up a lot of ambushes." ”

didn't expect such a scene, Li Ying was secretly surprised in her heart, looking at the mines buried in front of her, she muttered a little in her heart.

If it weren't for Yan Zhengfeng holding her, she would probably be dead if she couldn't even enter the door, but this can't be said to be careless, in fact, Li Ying doesn't know much about these military methods, so she almost suffered a big loss in front of such a normal-looking iron gate.

Looking at Yan Zhengfeng, Li Ying hesitated a little and asked, "How can we get in now." ”

But Yan Zhengfeng didn't pay attention to him, looking at the few mines buried in front of him, frowning slightly.

He knew that this mine, before the end of the world, was a standing weapon of the military, but the protection of this mine was so strict that it would not be touched by anyone at all, if not necessary.

If he didn't know the technique, it was impossible to disassemble the mine, and although he knew how to operate it, he hadn't tried it before and wasn't very sure.

"You stay away, I'll try."

After glancing at Li Ying, Yan Zhengfeng finally decided to dismantle the mines, after all, there is only one door to enter this acting studio, although there are walls around, but no one will know if there are mines behind these walls like this side, instead of taking such a risk, he might as well try it.

After all, Zhao Yi's current situation is very poor, and he must find a solution as soon as possible, but with Lu Ming taking care of him, even if the mine demolition fails, there will be no danger.

"Okay then." Li Ying understood what Yan Zhengfeng wanted to do, and instantly took a few steps back and said, "You be careful, I don't understand, so I won't help, and I'll go in when you finish dismantling the thunder." ”

Yan Zhengfeng nodded, did not continue to deal with Li Ying, but squatted down and worked beside the mine.

There is no tool to take advantage of, the process of dismantling the mine is very troublesome, and it is not smooth, when the last mine is dismantled, Yan Zhengfeng mistakenly detonated one of them, which caused a chain reaction, and the few that were originally removed before also exploded instantly.

The violent explosion shook the entire underground passage continuously, but the research institute obviously made relative anti-seismic measures, so it did not cause a collapse, but only a shock wave caused by the explosion in a semi-enclosed space, and the human braincase was a little dizzy.

After a long time, the dust dispersed, and Yan Zhengfeng shook off the dirt chips on his head in some embarrassment, and spit out a mouthful of phlegm.

It's unlucky, things didn't go well at the beginning, but if you want to talk about the impact, it's really not too big, it's just a little delayed the trip of a few people.

After relieving himself, Yan Zhengfeng took the lead in approaching the research institute, followed by everyone, carefully observing the surroundings, and after making sure that there was no ambush around, he walked to the interior of the research institute.

The internal passages are criss-crossed, there are many roads, people don't know which one to choose, and when they focus on Li Ying, Yan Zhengfeng's meaning is already quite obvious.

Li Ying identified the road and pointed to a passage on the right: "Let's go in from here, we can go directly to the back of the research institute, but it's better to leave someone at the door." ”

Looking in the direction pointed by Li Ying, Lu Ming glanced at the passage in front of him, a little stunned, wasn't this the passage he came to for the first time.

It was here that he met Dr. R directly, but he didn't move on when he was behind, so he didn't know what was behind the institute.

"What's wrong?" Li Ying saw the expression on Yan Zhengfeng's face, and asked suspiciously.

Yan Zhengfeng looked around and shook his head: "It's okay, let's go in." ”

Immediately, several people walked to the front of the passage, there was an inconspicuous metal door here than when he first came, Yan Zhengfeng used his strength to open the metal door easily.

When it was opened, it was an empty hallway, and I didn't know where it led.

However, it didn't take long for a few people to hear movement coming from the surrounding rooms.

"Roar!"

An inhuman roar came from the surrounding room, followed by the sound of heavy, dense footsteps, which made everyone's expressions solemn.

"Prepare for battle." Yan Zhengfeng frowned, and took out the dagger that had been with him for a long time from his waist.

Li Ying and Zhao Yi's reactions were also very fast, only Xu Haifei and Xu Haihai were a little vigilant, and the energy in their hands surged.

Instantly.

"Bang!"

A violent thud came through the metal doors of the surrounding rooms, followed by several large, hideous figures emerging from behind the broken metal doors, enveloping everyone in the narrow corridor.

Look at these monsters, they have humanoid bodies, but their bodies have changed more or less, there are eight in total, all of them are huge, and their dark eyes are full of ferocity, staring at everyone.

For this kind of monster, Yan Zhengfeng saw it for the first time, in fact, not only him, but everyone, including Lu Ming, had never seen this kind of thing before, but judging from the energy fluctuations emanating from their bodies, it didn't seem to be easy to mess with.

Eight monsters attacked everyone from different directions, the speed was not fast, but it gave people an extremely heavy sense of oppression, Yan Zhengfeng did not dare to be careless, and took the lead against one of them.
