However, even if those robots needed weird things to operate, Yang Song did not choose to destroy them. On the contrary, he collected them into his storage space and would find the opportunity to research them and make them be able to operate in a normal way.

After doing all this, Yang Song simply walked back to the Resurrection Chamber.

Previously, when Zhang Yin and Doctor Leng were alive, Zhang Yin declared that he would release "those things" and let them destroy the world.

Thinking of this, Yang Song took out the slender glass screen that he had collected from the Corpse Controller No. 1 or Qiao Tao.

Yang Song looked at the still visible red button on the glass screen for a second before he directly pressed the exit icon.

Then, Yang Song started to explore this black-tech product.

Not long after, Yang Song finished and found that this was simply a remote control of this Zero Green District Base.

As long as he had this controller, Yang Song could go to any department he wished to. In addition, with this remote control, he also had the power to open some forbidden places in the entire secret base and control the… life and death of every person in this secret base excluding the district chief.

Speaking of this, Yang Song estimated that this remote control should originally belong to the district chief, but it was stolen by Zhang Yin, somehow.

At the same time, this remote control should require high permission in order to operate it. But Zhang Yin could also crack the password of this remote control or what?

As Yang Song continued to think about it, he thought of the scene where Zhang Yin said that the "red button" of the remote control was created by him?

Then, did Zhang Yin also participate in the process of developing this remote control, so that was the reason why he could use it?

"Maybe that must be that case," Yang Song felt that it should be that way.

Soon, Yang Song suddenly thought of what Doctor Leng had said. So far, Zhang Yin had already destroyed three departments. So in other words, there were still other departments that had people who were still alive? Or what?

With that thought in mind, Yang Song turned around and left the Resurrection Chamber and left the Resurrection Department.

Then, he walked to the elevator and began to operate the remote control.

On the remote control, Yang Song tapped on the word "Emotionless Department" and waited for a few seconds.

"Beep! Welcome, District Chief. The entrance to the Emotionless Department has been unlocked. Please tap on the screen to open the entrance."

…

In a short time, the door of the elevator opened and Yang Song walked out. But what greeted his sight made him sluggish for a while.

This Emotionless Department was a wide and flat ground without any rooms. However, in this department, there were countless human-sized robots and plants.

Each robot was digging the ground and planting the plant stiffly. However, it seemed like the work took too much energy from them. So after each of them planted the plants for 20 minutes, they would stop and walk to recharge themselves the battery.

"It seems like these low-level robots are not perfect… no, it should the energy core and the battery level that has the problem. Each robot can only last for 20 minutes… this is just too short."

Yang Song then simply left the weird Emotionless Department and went to the Secret Department, which was the real secret vault of the Zero Green District Base.

…

As soon as Yang Song arrived at the entrance of the Secret Department, four 2-meter-tall robust-looking robots immediately detected him and stood in front of him, blocking his way.

But Yang Song did not feel scared or anything. He also stopped his pace and took out the remote control and connected it with the network of the Secret Department.

After the network was connected, a switch icon immediately popped up on the screen and Yang Song unhurriedly pressed on it.

The four robots then timely went back to their place and Yang Song went to scan his identity. Currently, he was in the appearance of Doctor Leng.

Although Yang Song was not sure whether this Doctor Leng was the district chief of this secret base or not, he was pretty sure that he was a high-level member of the Zero Green Secret Base.

This was based on the fact that he said that he had participated in the creation of the Corpse Controller.

With such a high-level ability, it would be strange if he was not a high-rank member of the Zero Green District Base. After all, he should've been working in this place for many years. If he did not have any position after so many years, wouldn't he have resigned a long time ago?

So to keep a valuable person like him, the high-level management team of the Zero Green District Base must promote him to at least the level of the branch chief.

The Secret Department was actually the place that only the branch chief could enter, so the security must be extremely tight.

At the entrance, Yang Song scanned his pupils, his face, and his voice. Fortunately, Yang Song's God-level Disguise Technique really lived up to its name. He could perfectly copy any appearance, voice, and fine details of any person.

The super thick and round-looking door of the Secret Department began to spin around for a few seconds before a "puff" sound was heard. Some mist appeared from the bottom of the entrance and lingered around the entrance.

Yang Song then entered the Secret Department without any hesitation.

The door immediately closed back tightly.

Yang Song then began to look at the things inside the Secret Department.

Strictly speaking, this place was not exactly a place where one would work because there were many treasures such as gold, diamond, various gems, and so on.

There were also some special products such as the Healing Elixirs, Healing Pills, Strength Boosting Pills, and even… the Final Booster.

Seeing this, Yang Song started to think of a possibility and wondered, "Then, is it the Zero Green District Base that develops the Final Booster?"

The possibility of this was extremely high. A weird place such as the Zero Green District Base really had the ability to develop such a weird pill.

After all, they could even create the Corpse Controller and some weird monsters, so creating such a sinister pill was not hard for them, right?

Yang Song then ignored this for now and looked at the thing in the middle of the big hall.

It was a solid silver rectangular stand, on it was a floating spherical ball that ignored gravity while emitting a faint white light.

Yang Song did not feel any strange energy from it, nor did he feel any danger. So he went to touch it without much thought.

As soon as his finger came into contact with the ball, the ball immediately fell on the flat top of the stand slowly before it cracked.

But Yang Song was not worried about it because the ball was actually only a holographic projection produced by the black technology of this place.

After the ball cracked, many big holographic screens appeared and floated before Yang Song.

Yang Song looked at the big screens roughly and soon understood what this ball was as well as its role.

It turned out that this ball was the virtual storage of this Zero Green District Base. All kinds of information such as the information of the employees, robots, abyssal beasts, humans used as guinea pigs of this place, and so on could be found in this virtual storage ball.

However, it was only limited to this branch. Information about the main station of the Zero Green District Base could not be found at all, not even the slightest of it.

If it weren't for the fact that Doctor Leng revealed that there was still the main base, Yang Song was afraid that he would've never known about it and would've thought that after the death of Doctor Leng, this secret base would end.

"It seems like the information about the main base can only be found in the memory of Doctor Leng. It would be great if the system can grant me the ability to read memories of both dead and living people," Yang Song deliberately thought this and wanted to let the system hear his wish.

But as always, if it did not have anything important thing to announce or if Yang Song did not have any important questions to ask, the system would always stay silent like a piece of a dead log.

If the system had a face, Yang Song estimated that it would look like a "dead lifeless fish" and it only responded when it felt like it.

Yang Song put this messy thought aside and started to look through the information on the holographic screens again. This time, he used his advantage as a cultivator and read everything speedily and carefully at the same time.
