After reading the information on the holographic screens, Yang Song found that Doctor Leng was really the chief of this place.

More than that, he also had a more precise understanding of all the departments in the Zero Green District Base.

Totally, there were six departments such as the Death Department, Healing Department, Resurrection Department, Emotionless Department, Secret Department, and Protection Department.

So there was only the Protection Department that Yang Song had not visited yet. But he was not worried about it because the Protection Department only had robots and no humans there.

To control those robots, one exactly needed the remote control in Yang Song's hand.

Thinking of this, Yang Song also knew why Zhang Yin did not call those robots out. To call out those robots, or to be more precise, the only person who could call out those robots was Doctor Leng.

So in the final say, Doctor Leng was the chief of this branch of the Zero Green District Base, and Zhang Yin somehow stole the remote control from him and killed everyone.

After that, he planned to release "those things"… was what Zhang Yin said.

As for what "those things" were, Yang Song probably had a guess in mind. As far as the information he had just read was concerned, there were indeed only six departments, but it did not mean that there were no other hidden places.

Virus Storage Chamber – this was the place where many kinds of viruses were researched and stored inside. However, only Doctor Leng and other top-level people knew about this place, but it was unfortunate that the top-level people also included Zhang Yin.

Regarding Zhang Yin, Yang Song also found out the source of his hatred. When Zhang Yin was young, his parents were also scientists of the Zero Green District Base.

However, his parents somehow violated the rules of the Zero Green District Base by revealing important information to the outside world and they were punished to death.

But even crueler than that was the young Zhang Yin was also involved in the affairs of his parents.

It was not that he was involved in the leakage of information, but the Zero Green District Base had decided to also punish him by torturing him and brainwashing him.

Yang Song felt that this kind of rule was similar to the ancient rule of the ancient dynasties of C Country in the past. If a family member committed a crime, then the whole family members would also bear the punishments together.

But Yang Song did not know why after being brainwashed for so many years, Zhang Yin still retained his sense and was actually not brainwashed at all.

However, when he thought of other information about Zhang Yin, Yang Song instantly knew the reason.

Zhang Yin was a genius, his brain was unusually smart and he had an ability that allowed him to remember nearly every event of his life with great precision.

Hyperthymesia – this was the scientific name of that ability.

But in Yang Song's understanding, it was because Zhang Yin had a strong "soul" that allowed him to resist the brainwashing and the torture of the mind.

In cultivation terms, this kind of people had great talents in cultivation. But it was not because of his strong soul, but his strong ability to endure the hardships.

Some people might also have a strong soul, but even so, their ability to endure was low, and thus their cultivation realm was not so great in the end even if they could cultivate fast in the initial stage.

"A pity, if Zhang Yin was alive… maybe I could accept him as one of my people and cultivate him into a strong man. By then, the system would issue rewards for me."

Yang Song sighed in a slight depression that he missed such a potential person. But it was also find, because Zhang Yin's mind had already been corroded by hatred and the strong desire to revenge.

Otherwise, he would not declare to destroy the world at all. So even if he could cultivation, he would have a Heart Demon in his future cultivation for sure.

Yang Song dispelled the messy thoughts and looked at the remote control in his hand again.

He did not plan to go to the Protection Department, for the time being, he wanted to go to the Main Control Center.

That was the place that monitored everything that happened in the entire Zero Green District Base and its power in the base was only second to Doctor Leng.

But what Yang Song found fortunate regarding this was that the person in charge of the Main Control Center was artificial intelligence.

The reason why the main base of the Zero Green District Base was not alerted yet was that Zhang Yin had already put the artificial intelligence into a deep sleep mode.

The reason Zhang Yin did that was not that he was afraid of the main base knowing the situation here.

For one, Zhang Yin himself did not know the existence of the main base, and another thing was that Zhang Yin was afraid that the A.I could detect the situation of the entire base and send the robots from the Protection Department to capture him.

Anyway, it was a good thing for Yang Song. Otherwise, he would not really have time to explore this place at all since the beginning.

Now that Yang Song had the remote control in his hands, he was no different from the master of this entire place.

After touching here and there on the remote control, Yang Song finally found the entrance to the Main Control Center.

It turned out that the Main Control Center was positioned right inside the Secret Department.

With a click, an entrance opened at the end of the big hall and Yang Song entered without any hesitation.

Before entering, Yang Song had expected the Main Control Center to look very futuristic and full of amazing technical equipment.

But when he really entered, he was stunned.

It was not a big room and there were no such things as black tech equipment or futuristic sensation.

In the entire room, there was only a solid bed made of unknown material and a child with green hair.

He was simply a cute boy with green hair and green clothes, and on the shirt, there was the word "Zero".

The little boy looked to be about the same age as Yang Mei'er. He was sleeping, and he seemed to be sleeping very peacefully.

But here came the questions, "But what about the artificial intelligence of the Zero Green District Base? What about the necessary equipment used to monitor the entire base? How come there's a child in this secret place?..."

There were just too many questions that came in Yang Song's mind. It was a pity that there was no one to answer the question.

Then Yang Song's eyes fell on the little boy again, "Could this child be the artificial intelligence?"

The possibility was not high but was it was not low either. After all, this was the Zero Green District Base, a secret base that could simply create many weird things.

"Maybe this boy is a robot? Or he is just a simple human, but his brain has a chip planted inside?" Yang Song wondered.

All the scientists in the Zero Green District Base all had chips planted inside their hearts, so having a chip planted inside the brain was not really weird.

So to find out the answer, Yang Song simply injected his Spiritual Sense into the body of the child.

After inspecting the body of the boy, Yang Song found out that every part of his body was made of steel and wire. However, his head was an exception. This boy had… a human brain!

So in other words, he was a half-human half-robot existence.

Although this looked and sounded very cool, Yang Song did not appreciate this very much.

Maybe the Zero Green District Base gave a chance for this little boy to live with a robotic body, however, he was imprisoned here and was kept as a worker, which was simply too inhumane!

Maybe this robotic boy was created using the same principle as those robots that Yang Song had collected previously. But those robots needed a human brain and a human heart, while this boy only had a human brain. His heart was made of steel.

But Yang Song was not in a hurry to wake this boy up, he wanted to store him in his storage space and bring him out of this place.

He was not sure whether he could store him in his storage space since only objects could be stored inside, so he decided to ask the system.

"System, can I store this boy in my storage space?" He asked tentatively.

There were a few seconds of silence, then the system replied coldly, [Can.]

Yang Song breathed a sigh of relief and waved his hand. The boy, along with the solid bed, disappeared from the place on the spot.
