The sky thought was conjectured by the dragon and phoenix pattern on the shell of the robot's chest cavity. This was determined when a space inside the robot's chest cavity that could accommodate adults was empty, and it was like the operation. It was probably because of this reason that they took out the four square things before.

And from the beginning, the sky remembered the names of the four robots. The first one opened was the sky, and then the south, north and south. There were eight holes in this room that could allow the robot to be inserted into, which easily reminded people of this being related to the robot, and it seemed to be another mechanism.

However, because of the fact that the mechanism was turned on before, there were only three places for charging left. So the remaining robot was put on the order? So Tiankong's eyes noticed the body of the robot in the lead. Sure enough, the dragon and phoenix patterns were captured on its chest, so that the same patterns on the other robots could be discovered one by one.

If the four robots guard one quarter of the pattern, then this should represent a certain order. The pattern and the robot are both keys and the key to opening the mechanism. In this way, the sky's eyes return to the dents that appear after they open the mechanism.

Since it is confirmed that the robot has not much energy, this is also an obvious thing. Three hundred years have passed, and it is already a miracle that these robots can still remain the same, and it is rare to have only a little energy left in their body. Since they need to charge, they will not waste energy anymore. Since there are only two dents on the mechanism that is opened, it will definitely not be a random move, and will definitely play a certain role, such as the charging switch.

After being proficient in the sky for a while, he could quickly operate it. However, after walking a few steps back and forth, he stopped the "Tian" robot before the dent face wall. After all, there was not much energy in the robot's body and he could not continue to waste energy. If even the energy of manual operation was exhausted, the four of them could not move these four iron lumps.

The girl jumped in excitedly and started to operate without the explanation of the sky. She is worthy of being a genius in scientific research. Although she has not developed such a robot, she is not slower than the star masters like them. Instead, she operates better than the sky. After a while, she also parked the robot in front of the designated wall of the sky. Although she was still a little unsatisfied, she had to give up and walked back with a little discouragement.

Qin Zijun and his birthday were slightly behind. Although they were not steadily manipulated, they could barely stop the robot at the designated position. The two jumped out immediately, as if they didn't want to touch this iron lump at all.

"How is it, how do you feel?" Tiankong smiled and looked at the three of them and walked back to say. This is a rare opportunity. Tiankong did this to make them really enjoy their appetite. Since there are four robots in this place, there are also more numbers. Once an accident occurs, they can still control the robots, and it is impossible for them to deal with the Qin family.

As long as they control their energy, they can move freely in the base as robots without having to stay in the robots that do not obey their commands.

Qin Zijun and his birthday both shook their heads, not interested in this robot at all. What they cared more about was what they wanted to get. However, the girl seemed to be still unsatisfied with the desire she wanted to get. For her, these robots were the things they wanted to get the most.

"The performance is much better than the robot I made, and it is very stable and has sufficient power. It doesn't look like there is not much energy residue. If possible, you must move one back." The girl said without any concealment, not looking at the robot not far away. Obviously, she needs to study it carefully. After all, this is a robot that she has not "see" and is influenced by the girl, and it has an irresistible attraction to these machines.

Tiankong looked at the three people who had different reactions, but this was their most realistic reaction. They did not hide or pretend. However, the girl's wish might be disappointed. These robots probably would not follow her. After all, they were things left three hundred years ago. How could they listen to her instructions?

"Okay, be prepared. Girls should start the 'Sky' robot. How to use this dent, we still have to look at it." Girls responded and manually turned on the robot. The four of them stared at each other for fear that something would be missed.

The 'Tian' robot was turned on again, and it was exactly the same as the sky guessed. The other three robots started to start themselves in the order of the world and north. After inserting their arms into the hole in front of their bodies, the 'Tian' robot also raised its arms, clasped its fists and pressed it against the dent. As it moved forward step by step, the dent was pressed in and returned to the position where it could have swallowed to the elbows of both arms.

Then the robot stopped moving, but from the appearance, it can be seen that something inside seemed to be still operating. If the guess is good, it should be charging.

"But, how long do we have to wait for this?" I didn't feel relieved when the sky found an accurate method on my birthday. Although it was for charging, if it was too long, they would not be able to consume it. And there was no food and water around me. If it took several days to charge, it was still a question whether they could still have the ability to act at that time.

Since Duoer is left behind by the sky, I will naturally notice this. The time should not be too long, and the four robots are the products of technology three hundred years ago, so it doesn't take too long. Although it is a self-comfortable idea, I can only wait at this moment.

You should know that I tried to use external force to push two dents on my birthday, and even his ten-star strength could not be shaken at all, but this robot could do it easily. It can be seen that it is not brute force, but it also requires some kind of recognition from the robot. Otherwise, wouldn’t everyone be able to find this place?

The girl took over the words. She had an absolute say here. After all, even the sky could not reply with certainty. The girl has created many robots. Although the drawings are different, the functions are similar and time can be roughly calculated.

"Don't worry, Datou's charging time can provide his ordinary consumption in one night. Although this robot is similar to Datou, it is mainly because it is much more advanced than Datou in terms of energy reserves, and the time is enough for a few hours at most."

With the girl's answer, the three of them felt a little relieved. If it was a few hours, they could still wait. Now they have less than an hour of time. If they continue to calculate at this speed, they will have plenty of time.

The four of them did not have free time, but checked in the room again, hoping to find more clues. This is also a way out. Once these robots cannot operate for a long time, they cannot stay here. If they find another way out, it is naturally best. They will choose to leave when necessary and come in after safety.

However, this luck did not last, and the sky had already guessed this possibility. The places I encountered before could only leave at the end. Never once could retreat halfway or go in and out freely. Obviously, I was afraid that the secret would be exposed or targeted by someone who was interested. Once he left, those places would either collapse and destroy or be closed again. Without the method given to him by Duoer, it would be almost impossible to return to the ancient city.

The four of them sat back to back on the ground to rest. This was not a physical exhaustion, but an excessive amount of mental exhaustion. They may continue to do so in the future, so they must recover more energy as soon as possible. Maybe something dangerous will happen in the next moment.

The most at ease among the four people, the girl is the one who can't calm down at the same time. Her star-rated strength is low, so she naturally won't worry about personal safety. Everything is protected by the three of them. However, her eyes have never left the robot. After operating the robot, her little head has always thought about how to get one. If she missed this opportunity, even if she witnessed how to come here, she would probably not be able to imitate it.

The sky stopped resting as time watched, and put four square things into a complete piece and placed them in front of you to stare. Although the iron plate has never been useful, it is by no means a decorative function. However, with such a thin texture and only patterns, why should it be divided into four? Moreover, if the pattern of dragon and phoenix is ​​easy to carry, the size of a slap is enough.

He looked up at the robots around him, looked down at the four iron plates, and could not see how to use them. He could only guess in his heart that this would be used later. However, since such an obvious thing is not useful for the time being, why not give it to him at the last time?

I gave it to him from the beginning, but it was so difficult that the robot was so confident that it would not be targeted by those who were interested, or was snatched away by those around me? Or was this something that had no effect at all, it was just a trick?

The sky scratched his head, and these questions about breaking his head made him breathe a sigh of relief. How quiet the four people were, his sigh was naturally captured by the three of them. The girl naturally turned her head and looked at the sky, which was still frowning and pondering, and asked: "Are you still thinking about the meaning of the four things to express?"

"Yeah." Tian Kong responded, and the four of them turned around, sat down to form a square, put the four iron plates in the middle, and said, "I haven't figured this out yet. If there is a mechanism here, then these four things must have other uses. Otherwise, the robot wouldn't have said that it would be possible to come in at the beginning!"

And even if he needed the "key" to open it, this was the first time that such a big thing was used. This was a little different from the previous method. Moreover, since he could discover the secret here, someone in the Qin family would definitely be able to discover it. Tiankong didn't think that his own wisdom had reached a point where no one could reach it. It was just that he had many clues, and was cautious and not careless.

Since this is the case, did the Qin family really not find this underground place? If you have to find something different, then it is what the girl said. She discovered four robots, and after getting close to him, these robots started. Then naturally, they would think that this is related to the two of them, and it is the key to letting these four robots run.

But this brought the problem back to the origin, and he had disguised himself. How could these robots confirm his identity before they were started? This was a disguised disguise that he could not even find on his birthday. His appearance, with the strength of the Qin family, can definitely do it unless the robot's intelligence has reached a terrifying level.

If these methods are ruled out, is the method by which the robot can confirm his identity because of the dragon chain or the golden crystal in his body? If this is the case, he is still acceptable, which means that the robot has the same thing, but it still needs to be disassembled to see it. I haven't seen these things before.

Moreover, the energy in this place is obviously isolated from the part occupied by the Qin family. The Qin family cannot control the place and does not obtain any information here. It can be seen that this is part of the independent base. Then, there may not be no complete composition and total equipment for controlling the base.

Thinking of this, the sky was even more eager to go in and take a look. If it could be found, it would be much easier to eradicate the Qin family. With Chen Xingfan's remote assistance, it is undoubtedly easy to control these robots and the facilities of the base. They cut off water and electricity and air circulation, and they can almost destroy the Qin family without any action, in this base they think is solid!

But now we have to wait until the robot is fully charged, but we also have to find another use of these four iron plates. Seeing the three of them thinking, the sky had to stand up and pace around the room. It seems that it would take an opportunity to find the use of the four iron plates, otherwise it would be difficult to find a way out in a confined mind.

This is not the sky is full of stunningness. This place is left behind by Duoer, and it is a place to be reserved for him as a base. So how can the things left behind be ordinary? Even if there is a little possibility, he will have to dig it out. Perhaps he can find some clues about three hundred years ago. This is why the sky has been searching for clues.

Moreover, since this place has been found three hundred years ago, even if it is cleaned up, you may still find the things left in the inconspicuous place back then. These may be clues.

The three of them looked at the sky who had not given up yet and shook their heads secretly. Obviously they wanted to help the sky. There might be something they wanted here, but they had tried their best. This is not like guessing riddles to give you a complete riddle, just guess it. Now this is a place they have never touched before, anything can happen, and the mechanism here may not be so easy to crack. Otherwise, it would not be stumped by the sky, and the Qin family had already discovered this place.

The atmosphere in the room solidified like this. The four of them were thinking about what was happening in their hearts, and only the sound of footsteps in the sky kept echoing in the room.

"Buzz." The robot heard a buzzing sound without warning. The four of them immediately looked at them. After waiting for so long, they were waiting for this moment. The charging might have been completed.

The four of them gathered together and stood in front of the robot. "Tian" slowly pulled back his arms, and then the other three robots also made the same moves and walked over on the ground.

During this process, the sky glanced at the charging port, and there was no change as before. It can be seen that this did not come with any mechanism. Then the next four robots should have some movement, otherwise they would not be able to afford it if this continues.

The four people immediately formed a triangle and protected the girl in the middle again because the robot surrounded them and did the same thing as before. They held the iron plate in their right hand and stretched left and right on the shoulder of the robot at a dot on the square. The iron plate on the top of the four people's heads, which was made into a complete pattern, lit up a faint light again.

"I won't come again this time, right?" Qin Zijun said immediately in surprise. When they saw it, they felt nervous. If they did this time and consumed energy and had to be recharged, how could they afford to delay? And I don't know how many times it would take to use such a move. If it took too long and could not leave halfway, then because the girl disappeared, the robots in the big head would definitely be the primary target of doubt. And the empty place there would definitely be discovered by the Qin family. This would make the Qin family prepare and it would be difficult for them to take action.

Sure enough, the four people were shining with dazzling light in front of them, and the centrifugal attraction came from their bodies. The four people held hands, as if conveying some information. After a while, the four people regained their vision and couldn't help but sigh that Qin Zijun's crow mouth really said something, and whatever happened.

The place I saw was still a room, with two holes on the four walls. Obviously, it was still a place for the robot to charge. After the leader of the "Tian" robot opened the mechanism, the four robots stopped in place, as if they were still waiting for them to manually operate to the charging position.

"Oh, come again." Qin Zijun was about to walk up to operate the robot in dejected manner, but was stopped by the sky.

The three of them looked at the sky in confusion. Is it difficult to see this time different from the previous operation? But the robot's movements were almost exactly the same as the room: "What's wrong with the sky? Is there anything wrong with it?"
Chapter completed!
