Getting closer, the three of them saw that there were five squares on the left and right sides of the secret door, which were engraved with a pattern of numbers, from zero to nine, which was like a password disk, Bai Yi pointed to these grids and signaled to the other two, it is not possible to attack, now the only way to come up with a password is to do it. (Castle of Black Iron)

It is not easy for the three people who know nothing about this ship to come up with a matching password, Bai Yi felt crazy at that moment, Bai Yi motioned for the other two to stop there, and he groped up and down the hull, he felt that he was doing something in vain, and he had to follow his instincts......

After groping for a long time, Bai Yi suddenly thought of the mast, he secretly scolded himself for ignoring this point, the horse swam over, pulling the mast, the flag on it was not intact, but the words on it were faintly visible, Bai Yi did not dare to reach out to touch it, lest this touch would make it fall apart and completely cease to exist.

Bai Yi shouted in his heart that it was so lucky, the year number on it was still faintly visible, coupled with the iconic Cao transport ship structure of the Yuan Dynasty, Bai Yi already knew when this was the ship, during the reign of Kublai Khan! Then there must be something to do with Kublai Khan.

He returned to the secret door of the hull and made an OK gesture at the two, Tang Sancheng was so excited that he danced with his hands, at this time, the most reliable thing was really Bai Yi!

Bai Yi stretched out his hand and pressed the grid to the left, quickly pressed four numbers, then turned to the right, and also pressed four numbers, when he touched those grids, every time he pressed it, Bai Yi heard a "squeak", which was more certain that this was the conclusion of the cipher disk......

The eyes of the two moved with Bai Yi's movements, infinite expectations, Bai Yi finished pressing, there was no movement at all in the secret door, he was a little annoyed, and punched the hull of the ship, it doesn't make sense, for a person, the day of birth must be the most important, for Kublai Khan, there is still a year very important, this year is the day he became the first emperor of the Yuan Dynasty, Kublai Khan was born in 1215, and became the first emperor of the Yuan Dynasty in 1271, so the passwords set by Bai Yi are 1215 and 1271. The number 1215 must be correct, because there is no abnormal sound like the right side, and the right side is set to 1271, so what's wrong?

Bai Yi tried desperately to calm himself down, what other days did Kublai Khan never forget? The name of the year of death is unlikely, what could it be? Bai Yi recalled all the information about Kublai Khan in his mind, which naturally included the Khan dispute, when Möngke Khan died, leaving behind three younger brothers, Kublai Khan, Hulegu and Ali Buge, one of whom would become the future Great Khan of the Mongol Empire. （）

Among them, Hülegü became the Khan of Persia in 1256, far away from the Mongolian steppes, and did not ask for the throne of the Great Khan, and the rest was the dispute between Kublai Khan and Ali Buge. The dispute between the two was fierce, and Ali Buge, as the youngest son, had become the ruler of the Mongol Khanate itself, and camped in the Mongol capitals of Hala and Lin, and was preparing to convene the Kuriltai in Mongolia to ensure that he was elected as the Great Khan......

Kublai Khan, however, was ahead of Ali Buge, led his army north from Wuchang, and established a base camp in Kaiping, China, where he was proclaimed Great Khan by his army on June 4, 1260, at the age of forty-four.

This time Kublai Khan became the Great Khan, and he did not follow the rules left by Genghis Khan, so he did not receive ordinary support, but this year was the first time that Kublai Khan was respected as the Great Khan, and this year also had great significance for him.

Yes, 1260, Bai Yi pressed the password again, the password was pressed, the secret door creaked open, and as soon as the three of them entered, the secret door behind them immediately closed. （）

"Strange." Bai Yi thought in his heart: "Why can't the water flow into the cabin? “

As soon as the secret door opened just now, according to the normal physical principle, the water should rush in immediately, but the water flow is just spinning around the secret door, but it can't get in, God! Bai Yi saw a lot of strange phenomena and didn't think so, but Tang Sancheng was fascinated by this vision, and stood at the secret door for a while.

The three of them went in, and they didn't dare to be careless, although the water did not pour in, they were still cautious, still wearing diving suits, not daring to take them off, and wearing masks, the boat has been closed, if there is any toxic gas derived from it, this one takes off the mask, but it is self-defeating, and his life is important.

It was pitch black inside, the three of them had already prepared, brought waterproof headlamps, put them on their heads, and finally had some light in front of them, oh my God, countless boxes were placed together, and by visual inspection, there were forty or fifty boxes, because there was no flooding, these boxes were not damaged at all, and they were sealed and covered with red seals!

Tang Sancheng patted those boxes excitedly, pointed at Bai Yi, and gave a thumbs up, this yaksha didn't see the slightest shadow, but found some treasure chests first, no matter what, this time, it's worth a lot!

Bai Yi walked to those boxes, looked at the Zhu Yin on it, and looked at the lock on the box, and immediately found that there was a mystery inside, this lock looked inconspicuous, but there were serrations up and down, just like a crocodile's mouth, this kind of mechanism, if you open it directly by hand, it will naturally be hit, but if you force it to open it with external force, it will be over, there is a mechanism inside this box that is connected with the sawtooth, once the external damage is sensed, the mechanism inside will naturally start, and no matter how many treasures in the box will turn into ashes, this is an advanced means used to prevent theft in ancient times.

Tang Sancheng bumped Bai Yi with his buttocks, meaning to ask him how to open it, it was not convenient for everyone to speak, Bai Yi also thought that the body language was too troublesome, so he directly ignored Tang Sancheng, and just concentrated on studying the mechanism on the box, this sawtooth is in two rows, Bai Yi looked back and forth several times with the headlamp, and finally found something, in the upper and lower rows, each has a sawtooth that is the key, you need to press and hold it at the same time, and the box can naturally be opened, but which two are you, you will have to hit the luck, if you hit it wrong, it will also activate the mechanism.

Bai Yi counted, there were fifteen sawtooth on the top and bottom, a total of thirty, to find a combination of two among the thirty, this possibility was too many, but they only had one chance, and if they didn't succeed once, the game was over.

Rub, do you want to give up? Bai Yi felt that he was sweating, he wanted to give up, but he couldn't say anything about the expectant eyes of the Seven Evils and Tang Sancheng, and besides, his curiosity had already risen!

Bai Yi suddenly left the box far away, closed his eyes and thought there, he was very engrossed, Tang Sancheng and the Seven Demons didn't bother him, they just stood there and looked at him.

Finally, Bai Yi opened his eyes, a chance, just like this, let's fight, chance is often linked to luck, their group has always been favored by the goddess of luck, what are they afraid of!

Bai Yi returned to his place, pointed at himself, pointed at the two of them, and then spread his hands, Tang Sancheng was puzzled, the Seven Evils understood, and everyone would probably die together later, Tang Sancheng didn't understand, he kept kicking his feet, urging Bai Yi to hurry up, Bai Yi gave him a roll of the eyes, and finally began to unpack.

Bai Yi counted the top sawtooth to the sixth, put his left hand on it, and counted the lower sawtooth to the ninth, put his right hand on it, and then, he raised his head, took a deep breath, and pressed it with both hands at the same time, and after a long sound, ......the box automatically popped open!

At that moment, Bai Yi's head was turned sideways, beware of any monster inside sticking out his head, no! He turned his head, but his face immediately changed, and there was really no monster poking its head out of it, but there was a monster lying inside!

Tang Sancheng was already stunned there, unconsciously approaching the Seven Evils, the skeleton lying inside did not look like an ordinary person, especially with a bone protruding from its tail...... Wait, Tang Sancheng raised his eyes and looked at Bai Yi, his mouth opened, this, isn't this the bones of the Yaksha!
