After wandering around the huge No. 3 safe house for several times, sun Cheng came to the center. First, he collected all the engineering robots that had been closed by revenge after completing the construction work into the spherical space.
After completing these, he went to the corner of house 3 again and put dozens of boxes stacked there into the spherical space.
These boxes are standard boxes one meter high, one meter wide and two meters long. After he last returned to the real world, he asked the industrial robots at base 1 to weld them with steel, which are specially used to transport construction waste and construction materials.
Now, some of them are empty, some are filled with construction waste, and some are filled with unused cement, steel bars, alloys and other materials.
When the safe house is completed, the rest of the land is to add things to it. The unused materials should not be used up.
"More than 200 square meters... It''s a pity to only store some materials for emergency... Maybe you can put some furniture, office and living equipment here..."
On weekdays, although sun Cheng will not live in a safe house.
However, his experience in the "Transformers universe" made him more and more cautious and prepared for a rainy day. Now he is more used to making the best preparations in advance.
It is called the safe house. In addition to providing security for sun Cheng when necessary, it also needs to ensure that he can successfully escape from life in a crisis.
Therefore, the [safe house] naturally does not have only one entrance and exit.
After staying in room 3 for a while, sun Cheng walked to the other side facing the entrance.
There is a password door exactly the same as the previous ones on the wall over there. Revenge has already been waiting there.
This time, sun Cheng squatted slightly and aimed his right eye at the display screen.
Not long after, a scanning aperture appeared again on the screen. A non dazzling green light was emitted and aimed at his right eye. It disappeared in less than a second. The words "permission to pass" appeared on the screen.
"Click!"
When the code door opened, he walked into the last safe house without hurry and only slowed down slightly. After checking in room 4, sun Cheng went straight to the code door at the end of the room.
The safety house is as like as two peas in the front and the two is the same size. The room is designed for him to be stationed in the battle room.
He went straight to the end of No. 4 safe house, where there was also a password door. Sun Cheng, who was already very skilled in fingerprint decoding, stretched out a finger and verified his fingerprints. The one in front of him was very different from most password doors in the safe house. When he opened it, there was another elevator in front of him.
However, when people stood in front of the elevator door, sun Cheng didn''t open the elevator this time.
The exit on this side of the safe house leads to another villa in the community. After deciding to build a safe house, he inquired about the sale of nearby villas, and finally selected another villa directly behind the villa he originally bought, which is just separated from a row of villas.
Because it was purchased in the name of others, sun Cheng would not know the secret as long as he didn''t go in and out there at will.
Soon he turned and walked back in the same direction as when he was walking. It''s not that he didn''t want to go up and check it.
It''s the house that sun Chengxin bought not long ago. In order to cover up the fact that they built a safe house underground, it is also being decorated with great fanfare.
The decoration there is not done by engineering robots, but by a decoration company engaged in the design of high-end apartments and villas specially hired by him in Nandu.
At the beginning, because it was not clear how long the safe house below needed to be built, but also in order to cover up the possible noise during the construction below as much as possible, sun Cheng spent a lot of money to let the decoration company redesign the villa behind almost from inside to outside, so that even if the nearby houses heard the noise, They will only think that it came from the villa decorated in the back, and will not doubt that the sound came from the underground.
It is conservatively estimated that the decoration of the villa where the exit at the other end of No. 4 safe house is located will last for at least two months.
During this time, people should be arranged to watch the night. After all, the materials purchased for decoration are valuable.
So if it is not necessary, sun Cheng will not reveal the secret of the villa.
Soon he returned to the main building of the safe house again. Looking at the empty space, his heart surged up without reason.
"I didn''t think about it..."
After frowning and thinking for a while, he went through all the experiences after the return. After sun Cheng still didn''t find the reason for his uneasiness, he thought about it. Then he went to a corner of the house and reached out to the front.
At the next moment, a special container with a height and width of three meters and a length of about ten meters suddenly appeared in house 3.
"... it''s just that there''s nothing wrong with a layer of protection..."
Sun Cheng naturally knows what is contained in this container. All of them are new combat robots manufactured by base 2.
Originally, he wanted to go to No. 1 base in two days, let the defender wake up these combat robots, debug them on the way, and then take them back to the safe house for deployment.
But there was no reason to feel a burst of uneasiness, which immediately attracted the suspicious sun Cheng.
After two quick steps, I came to the left side of the container. The ground I saw was the same as the other sides of the box. I could not see any door locks or even welding marks.
To put it bluntly, it should be a slightly protruding alloy block in the center of the box.
"Revenge, open this security lock... The password is still..."
The protruding alloy block on the container is a safety lock.
However, different from those password locks on earth, this security lock is a special password lock produced by Decepticon engineers at the request of sun Cheng and with the manufacturing technology of Cybertron.
Its interior is exquisite to the nano level. If you want to open the security lock without violently destroying the box, you need to insert a nano level key and input the correct password in an internal micro verification chip.
Incidentally, the microchip in the safety lock is also connected with dozens of sensors and micro bombs welded in the box. Once the box temperature is detected to be too high and someone tries to cut the box violently, it will directly detonate the container according to the reserved safety rules.
This is also one of the means left by sun Cheng to ensure that his secrets are not leaked to the greatest extent.
After all, these special containers were specially made by Decepticon engineers to facilitate him to store items in the spherical space.
Most of these items were finally brought back to the real world by him.
"Yes, master!"
After revenge got his order, he quickly went to the safety lock of the container and stopped. He stretched out his slender right hand and held it on the slightly raised alloy block, and the fingertip of one finger immediately lit up slightly.
Although sun Cheng couldn''t see it, he knew that a nano bone spur had been stretched out of his revenge fingertip and inserted into the safety lock.
He didn''t have to wait long. With the crackling of the safety lock, there were two cracks on the surface where no welding marks could be seen, and they quickly shrunk around.
At the next moment, there was an exhaust sound from the closed container.
Without sun Cheng''s command, revenge opened the container door for him, and rows of humanoid steel machines like soldiers appeared in sun Cheng''s sight.
