There is a crisp "click" sound.

The large iron gate slowly retreated to both sides and disappeared into the stones.

Immediately afterwards, an extremely rich red poisonous gas floated over.

Xu Dong's heart trembled. Even though he was wearing a gas mask, he still held his breath and concentrated subconsciously, running the Heavenly Medicine Sutra, holding the holy dagger in his hand, and walked forward step by step.

He was wary of hidden weapons that might be hidden around him, but after walking for more than ten meters, nothing happened.

It seems that there is only poisonous smoke in this passage.

Soon, Xu Dong came to the second iron gate, and he opened it in the same way.

Immediately afterwards, a stronger poisonous smoke hit his face, with a smell of blood.

Xu Dong tensed up his nerves and did not go in immediately. Instead, he observed at the door.

Seeing that there was no danger, he continued to step forward and quietly came to the third iron gate.

It seems that because of the existence of the first two doors, the third door is very ordinary.

Xu Dong picked up the meteor needle, opened the lock, pushed the door open, and suddenly felt that his vision became brighter.

What suddenly opened up in front of us was a hall comparable to a football field.

There are various instruments and equipment in the hall, more than a dozen cubicles, observation rooms, data analysis rooms, collection rooms, etc.

Xu Dong was shocked. He knew he was in the right place. This was the laboratory.

"Deng~Deng~Deng~"

Before he could react, a burst of rapid footsteps suddenly sounded.

Immediately afterwards, two figures wearing chemical protective suits walked out of an office.

They held two test tubes in their hands. After seeing Xu Dong, their bodies visibly stiffened.

"call out!"

Xu Dong's entire body disappeared from the spot and appeared in front of the two of them in an instant.

The holy dagger in his hand slashed out without mercy!

"Chila!"

Blood splatters, two

The person's head was moved and he fell into a pool of blood.

With quick eyes and quick hands, Xu Dong instantly grabbed the fallen test tube, placed it on the table, and quickly disposed of the two corpses.

Immediately afterwards, he took off another person's chemical protective suit and put it on himself.

After doing all this, he started walking around the hall.

There are more than twenty tables here, filled with various bottles and jars, and there are also some glass particles and debris on the floor.

In the center, there is a huge display screen that is turned off.

Xu Dong quickly glanced around and suddenly heard a sound coming from the top of the building. He subconsciously looked to the side and suddenly discovered a staircase.

"Is it a meeting?"

Xu Dong didn't think much. After arranging his clothes, he ran up quickly.

The second floor is much smaller than the first floor, with offices one after another.

In the office of the person in charge, there were voices talking one after another, as if they were discussing something.

Xu Dong did not dare to disturb them, he walked to an office casually and pushed the door open.

no one.

The office is very tidy, with a large display window next to it filled with various documents and files, each with a number on it.

There are diagrams of human anatomy on the wall, as well as a bunch of research data.

Xu Dong came to his desk, opened the drawer and flipped through it a few times, and suddenly saw a notebook.

He opened it and looked at it for a few seconds, with a playful smile on his lips.

"The location of the laboratory has finally been determined. It is Beiling Pass. It is sparsely populated and has many large beasts. It is an excellent hiding place."

"Moreover, the local villagers are very feudal and believe in mountain gods. After investigation, they built a temple under the sacrificial temple.

It’s definitely a perfect choice for a large laboratory.”

"The laboratory has been successfully established and the S12 plan has been launched."

"We captured rats this week. They are all found in this restricted area and are used for experimental research."

"The rats could no longer meet our needs. After discussion, we targeted nearby villagers."

"Today is a happy day. Eighteen people have been brought to the laboratory. Our experiment can finally proceed to the next stage."

"The potion has been prepared, and the experimental subject reacted very violently. It is expected that the survival time will not exceed a week."

"Try to increase the concentration of the potion and conduct the experiment again."

"The experiment was successful. This potion is enough to cause a disaster."

Xu Dong squinted his eyes and read several pages in a row. He found that it was something like a diary, with some daily experiments clearly recorded in it. .??.

He quickly flipped through a few pages to see if there was any information about Experimental Subject No. 9.

Soon, he got the answer he wanted.

"Today is a day worth celebrating. No one expected that Experimental Subject No. 9 would mutate."

"The data before his experiment were very ordinary, but mutations still occurred. The success of Experiment No. 9 has given us a new research direction."

"Once the research is successful, this may change the situation of a country."

"Oh my God, Experimental Subject No. 9 is a monster. He is not afraid of high temperatures, bullets, and can't even feel pain."

"He is a beast that only knows killing. His strength, reaction, and agility are all amazing."

"Terrible, absolutely terrible!"

"Experiment No. 9 suddenly launched an attack and infected three experimenters in a row. After discussion, we decided that this was not an option and decided to release him and continue recording in a place with a wide field of vision.

Record all data."

"Experimental Subject No. 9 actually killed a wild boar weighing more than 200 kilograms. He is a natural warrior and the best killer."

"Unfortunately, although Experimental Subject No. 9 has terrifying power, it has completely lost its mind and is uncontrollable."

"If it cannot be controlled and stability cannot be maintained, the results of this research will be greatly compromised."

"We tried to tame Experimental Subject No. 9, but all ended in failure, but we did not give up."

"The latest plan was launched today to extract the genes of Experimental Subject No. 9 in order to replicate Legion No. 9."

"Hopefully we can succeed."

After Xu Dong read the last line, he was slightly stunned and thought about the matter quickly.

At the beginning, the purpose of these Yingguo people was just to study a kind of potion. As a result, during the research, Experimental Subject No. 9 suddenly mutated.

This change was completely beyond their expectations, but it brought them a huge surprise.

They discovered that No. 9 was a born warrior and wanted to replicate a legion.

"A terrible plan."

Xu Dong narrowed his eyes, quickly put away the diary, and then looked through the office.

Soon, he found the initial data of the potion in a file bag in the window.

"This is it!"

Xu Dong's eyes lit up and his expression was shocked.

With this batch of data, we can prescribe the right medicine and develop an antidote.

He carefully put away the files and quickly left the office.

Xu Dong knew very well that there was definitely something more precious in this laboratory, and that was the data analysis of the genes of Experiment No. 9.

But, he thought of the struggle and endless pain in No. 9's blood-red eyes...
