With Lu Xiaoyu's intellectual training for them before, Abu also found a way to crack this iron box. If the guess is correct, it should be possible to move the rolling thing to the other end of the box to open the chest. He's a genius, Abu was secretly excited.

However, because the iron box is very heavy, there is no way for one person to turn it, and if you want to make the things rolling inside move according to the lines on the iron box, you must lift and rotate it together with several strong men.

So Yelu Chu ordered someone to help Abu lift the iron box in its entirety, and turn it over according to Abu's instructions.

"You crouch down a little bit on the left." Abu looked at the first stripe on the iron box, and the instructions of the road needed to move the right thing inside the iron box forward, and the left side had to be tilted so that it could slowly roll down due to gravity.

Hearing only a "click", Abu approached the iron box and heard a clear sound of the beads rolling inside, and then stopped at the place where the stop indicated on the line was.

Sure enough, just as I expected, I was able to move the beads from the right end of the iron box to the left side by following the pattern on the iron box.

The next step is to move to the left, because the beads have no impetus in the iron box, so even if the box is moved to the left, the beads inside will not move in the slightest. But this is still not difficult for Abu after Lu Xiaoyu's mental training, he immediately thought that as long as the left hand of the two people carrying the box is lower, the beads inside will roll to the left due to gravity.

Sure enough, there was another "click", and the bead stopped at a point on the left again. Yelu Chucai, who was watching from the side, couldn't help but admire, where had they, the people who were fighting the world on horseback, seen these strange things, let alone how to solve the mysteries.

He asked Abu puzzled, "Brother Xian, you said that we Khitans are all good at riding horses and fighting and eating with their fists, who will study these strange things that require brains?" From the machine bed in Yelu Baoqian's house to the mechanism in this big iron box, if it weren't for the presence of a virtuous brother today, it is estimated that I would not have been able to crack it in my life. I don't believe that a person like Yelu Bao Qianli who can't read a few big characters will know how to crack this iron box. But how did such a thing come into their house, and who made it? ”

"I don't know about this little brother, maybe I won't know the true origin of this box until I open this box and see the contents inside!"

"Then what are you waiting for, Brother Xian, quickly crack this box! I don't think you'll have the slightest difficulty cracking this chest. ”

"I can't say that there is no difficulty, but I still have to wait until this mechanism is finished and see if I can open this iron box directly. It is said that such a well-made wooden bed can appear in this mansion of thousands of miles, and this mysterious iron box does make people a little suspicious, but maybe this box is not owned by them. ”

"Well, Brother Xian, you are right, these soldiers around the emperor did not do less things like chickens and dogs and thieves, and they also hid a lot of treasures, but the emperor felt that it was not easy for them to help him fight the world, so he turned a blind eye and regarded it as a reward for them. I guess most of this iron box is from a foreign country. Yelu Chu guessed.

Yelu Chucai said here, and Abu continued to command the movement of the beads in the iron box in an orderly manner. The last three steering beads were left to reach the left end of the iron box, but there was a little trouble.

There are two forks in the road, one is a dead end and the other is a living road that can be continued. But every time it passes through this fork, the bead will involuntarily drill into the dead end, move it out again, and it will return to the previous starting point.

After several attempts, the beads could not be brought back on the right path, which made Abu a little anxious. Abu took it upon himself, carrying the left side of the iron box to keep the person holding it on the right to hold it still, and he let the beads move slowly along the edge of the lines, and then squatted abruptly when he was about to pass the fork in the road, so that the beads could enter the path of life in an instant.

The first time Abu moved a little slower and the bead went astray, the second time it was a little late, and the third time Abu learned from the experience of the previous two times, and simply squatted down, so that the bead kept moving against the side of the road, and sure enough, when it came to the fork in the road, the bead rolled directly from above into the road ahead.

"It's done!" It turns out that the passage leading to the living path is only a small corner, and if you don't enter close to the edge, you will never want to bring the beads in.

After going through this difficulty, the next passage is much easier. After a few turns, only to hear a "pop", the bead finally moved to the left end of the iron box.

"Brother Xian, is it time to open the box? Let me try! Yelu Chu tried hard to break the lid of the iron box, but after a long time of trying, he couldn't lift the lid.

"Huh? Brother Xian, what's going on? Isn't this bead already moving to the other side? It stands to reason that it should be able to be opened, why or not? Yelu Chucai shook off his palm, which had been pinched red throughout, and asked puzzledly.

Now that the beads are completely up to the left end of the box, and are fixed to that point, there should be no problem. The key should not be here, Abu has also said before, not necessarily after the beads move into place, they will be able to open the box, there should be something that has not been cracked. For example, there are two obvious depressions at the ends of the iron box.

Could it be that the last organ is here? Abu pressed the depression on one side with the mentality of giving it a try, and the depression was originally impossible to press, but now it can be pressed. Yelu Chucai also followed Abu's example and pressed down on the other side, but the box did not react at all, and the lid did not open automatically as expected. Yelu Chu didn't believe in evil, and tried to lift it up a few times, but he couldn't get the box open.

Just as he was about to give up, Abu noticed that the sides of the iron box seemed to have changed, and the sides that had been flat except for the two depressions suddenly protruded from each other.

Abu tried to pull it out slightly, like a small drawer, and the thing was pulled open. I see, this iron box is not a box that is opened from above at all, but an iron drawer that is pulled open from the side!
