Quick Wear: Host, are you playing here?

With this interruption, the atmosphere became a little more relaxed.

Turning to look at Song Yan, Song Yan had already walked out of the control room and arrived at the hall through the alloy door.

On the smooth floor, the man's tall figure stood tall.

Behind him was the sound of zombies knocking on the door, but there was no extra emotion on his face, only the coldness of a soldier.

His eyes scanned the entire lab, not knowing what he was looking for.

During this time, he met Hua Xia's eyes, and then he looked away after the latter raised her hand and greeted her with a smile.

The adjutant walked around the empty laboratory and went outside. He came to Song Yan and whispered, "Captain, I didn't find any mechanism."

This base is very large. From the size seen from the outside, to the various vacant laboratories inside, and measuring the length with your feet, it is roughly the same size as estimated by the naked eye from outside.

This means that there is no secret room in this laboratory.

However, the several black screens in the monitoring room just now did not know what they were monitoring.

Song Yan lowered his eyes and looked at the smooth floor under his feet, with uncertain emotions in his eyes. The white light above his head suddenly flickered at this moment.

The light in my eyes faded, but the floor was still glowing with a faint light, and then it disappeared in an instant.

The air became noisy, but within half a minute the light in the laboratory returned.

The light came on, Song Yan looked at the girl who was already standing in front of him, and said silently: "Don't run around."

Everyone checked the circuit and found that the power supply system outside might have been damaged by zombies.

Because of the panic and noise just now, the sound of zombies attacking outside increased instead of decreasing.

The impact sound became louder and louder.

"Captain, what should we do? Shall we rush out?"

"You're just waiting to die in there anyway, why torture me?"

Dr. Yuan has completed the calculations and roughly confirmed the existence of special variables, although he does not know what the special variables are now.

He walked out, the air was silent for a moment, and only the sound of a pair of leather boots tapping the floor could be heard.

The owner of the short boots kicking the floor kept moving, as if he was just kicking for fun.

The doctor looked at the place where she kicked and felt a headache. Just as he was about to ask her to move aside, he heard a click and the square piece of floor broke into pieces.

"......"

The ground caved in, revealing the space below, which was pitch black.

"........"

"Oh, there's a rat hole here." The girl pointed innocently at the hole in the floor where she had kicked it, and exclaimed with her hand covering her mouth.

"........"

Is this really not intentional?

Everyone gathered around and looked at that place. Under the floor tile, there was a steel plate under the light. The material was military grade.

The adjutant and his men looked at Song Yan. This material must be from the military.

"Dr. Yuan? This is......"

"......." Dr. Yuan took out a pair of glasses from his white research coat and put them on. "The following is confidential information of the institute. No outsiders are allowed to enter without the approval of the National Central Research Institute."

The confidentiality level inside is obviously equal to the security level.

Dr. Yuan comforted everyone: "Come with me and take shelter for one night. We will make a decision tomorrow based on the situation outside."

"That couldn't be better, Dr. Yuan." Xie Qingyang agreed.

Everyone's focus was on Yuan Rui. Hua Xia retreated to the outermost edge, but she felt a gaze coming from the side and did not move away.

"......." She blinked, "Brother~what are you looking at?"

"Do you know what's down there?" Song Yan lowered his voice.

Hua Xia nodded casually: "Didn't I say I know?"

"It's just some evidence in there. Oh, and by the way, the other researchers who died in the 'zombie riot' are also down there."

"Well......."

Before she could finish her words, Hua Xia was pulled aside by Song Yan and covered her mouth: "Stop talking."

"......"

250 Sigh, when will the host change his bad habit of loudly calling someone the murderer in front of the murderer?

How dangerous the murderer is!

The underground space is not as big as imagined. There is an oxygen supply system. Going down from the top, you will find that the steel plate made of special material is very deep. Below is the strongest place in the entire biological research base.

Unlike the research room above that was separated by glass, the space here was almost sealed off by solid materials of the same level.

In the space below, test tubes of liquids of various colors were placed with incomprehensible labels on them.

It's very messy, but there are signs of use.

Obviously, this is the real laboratory.

They went down to this underground space by taking the elevator. Now the elevator was closed and integrated into the wall, completely blocking out the light from outside.

Dr. Yuan probably didn't expect to come back, and reluctantly led everyone into the underground laboratory. His face was dark blue at this time, and it was difficult to disguise. His voice was commanding: "The laboratory information inside is not open to the public. There is an explosive device in the laboratory, so everyone stays here now and is not allowed to move at will!"

There was a strong smell of disinfectant in the air, coming from the darkness inside and rushing straight into my nose.

After receiving a positive answer, the doctor turned around and walked to the computer desk in the outer laboratory to do something.

He hadn't taken off his glasses since just now, and the data imported on the screen was calculating something.

Song Yan asked people to clean up the supplies that were brought in. If the zombies outside continued to besiege them, these supplies could only sustain everyone's food supply for two days.

After the adjutant finished reporting the count, he looked at the girl sitting on a chair that had been dragged from somewhere: "......Miss Luo, aren't you afraid?"

Speaking of which, I felt that I was asking unnecessary questions.

"Miss Luo, your knife is still..." in the car.

The adjutant was interrupted by Xie Qingyang's question behind him before he could finish his words.

"Captain Song, can you please take out the crystal core of the level 5 zombie and give it to the doctor for research?"

Xie Qingyang spoke frankly and his purpose was clear.

The crystal core of the level five zombie was taken out under the watchful eyes of everyone. Zombie crystal cores have been something that those with special abilities have been vying for since the end of the world.

The zombie crystal core is used to upgrade superpowers as if it is innate.

Seeing that Song Yan ignored him, Xie Qingyang stepped forward and asked, "Captain Song, do you want to secretly take the crystal core for yourself?"

Xie Qingyang's handsome face became a little distorted at this moment. He thought that this person's supernatural powers might be far superior to everyone else. Not only was he special, but he also had a level 5 crystal core in his hand. Wouldn't that be like adding wings to a tiger?

After that, returning to City B would probably be a big hassle.

"That won't do!" Hua Xia stood up and clapped her hands to express her agreement with Xie Qingyang.

"Miss Luo?"

"you......."

Xie Qingyang and the adjutant beside him were both confused. After all, Hua Xia had always shown that she was on Song Yan's side.

"What do you mean by 'I'?" Hua Xia turned around and extended her hand towards Song. "I think Xie... is right!"

"It's time to take it out! How could Captain Song secretly take the crystal core for himself?"
