Entering from the crystal dragon's mouth, the passage takes us to the depths of the mountain range, the more we go inside, the larger the space, if Emperor Qin chose the Jieshi Palace here for concealment, this should already be a very suitable location, but we have been to the bottom of the sea for so long, and we have not seen any large architectural palaces.

The only thing that makes us happy is that there is only one stone road leading to the front under our feet, at least we will not get lost in the submarine mountains, and the corpses of the Japanese and Jinyi guards can be seen everywhere along the way, hundreds of years ago they fought all the way here, Akai Yoshitaka said that in the last battle, Akai Nobu led the three thousand elites to all be missing, and it seems that these people should all be killed and injured in the Jieshi Golden Palace.

"There is a fork in the road." The man who was in front of him came back and said.

Xie Tianhui shouted loudly for me to check, and when I walked to the front, I saw the hole that extended to the left side of the mountain, the Jieshi Palace at the bottom of the sea was completely built by digging the mountain, because the mountain was to be excavated, so every excavation must be carefully calculated, otherwise it is extremely easy to cause collapse, although it is not a mausoleum here, but it is similar to building a mausoleum underground, of course, it is more difficult to require more careful at the bottom of the sea.

The chisel marks in the cave wall are very irregular, and they spread forward in a zigzag, and the entrance of the cave is not wide, which is incompatible with the majestic construction process outside, and the more you go inside, the narrower it becomes, and gradually there are corpses on the road.

Perhaps due to the lack of air circulation in the cave, the remains are still quite well preserved, judging by the clothes of the people who built the place, but each of the corpses found was hideous, with shriveled flesh clinging to the skeleton, and curved knuckles leaving visible scratches on the chest.

"All starved to death." I said after crouching on the ground and examining a corpse.

"What are these people digging this cave for?" Tian Ji asked with a torch in the back.

Walking to the end of the cave, where the corpses were piled up, and the rocks at the end were densely scratched and bloodstained, I looked around and finally realized the reason for digging this cave.

This is not the passage in the design of the Jieshi Golden Palace, but after the completion of the Jieshi Palace, the people who were trapped in it dug this passage together in order to escape, and at the beginning there were secretly hidden tools, and when the tools were broken in the end, these people had to dig with their hands.

"There are words here." The torch in Ling Zhihan's hand illuminated a nearby mountain wall.

There are crooked words on it, which should be carved in stone, and the content of the text on it confirms my speculation, these words should have been carved by Minfu before he died, clearly recording everything that happened here.

From the content of the text, we are surprised to find that these people have no idea what they are building, or even where they are, they are brought here blindfolded, and the main responsibility is to dig a passage in the mountain.

When the project was completed, they were exterminated en masse, and the remains we see today are the people who survived the massacre, and they tried to get out of here, but there was no way out, so they had to dig a passage in the hope of escaping.

"In this way, the Jieshi Golden Palace is not built uniformly, and these people don't know what they built until they die, which shows that the Jieshi Palace was built in sections." I took a deep breath and watched the horrific scene in front of me, my voice low. "Every time a section of the project is completed, the people who participate will be killed, and then the new people will be sent here, so they don't know where they are, let alone what they are building."

"One will succeed and ten thousand bones will wither, Emperor Qin has interpreted this sentence vividly, I don't know how many dry bones have been piled up in this Jieshi Golden Palace at the bottom of the sea." The palace lord sighed heavily. "Poor these people, since the day they were sent here, they are destined to have no return, even if they really dig through the mountain, they will only face a bottomless seabed."

"However, it can also be seen from the side that Emperor Qin attached great importance to the Jieshi Golden Palace, and built pits to kill people in sections, all in order to preserve the secrets of the Jieshi Palace, which shows that there must be extremely important things in it." Ling Zhihan said.

Coming out of the cave, we continued along the passage illuminated by the fire trough, and after walking for a long time, the palace lord at the front stopped, and in front of us was a small square stone chamber, and the road leading to the back appeared on the opposite side of the stone chamber.

This one feels clean, but it's a little abnormal.

Along the way, we could see the corpses of the Japanese or the Jinyi Guard, but the square stone chamber was empty, and where we stood, there were more than a dozen corpses lying on the ground, intertwined with each other, and the knives in each hand pierced each other's bodies.

Presumably, there was an unusually tragic battle here, and the traces of being slashed by knives could be clearly seen on the stone wall, but there was nothing in the stone chamber in front of us, but the corpses could be seen in the passage opposite the stone chamber.

This place is unusual, be careful, he slowly moved to the edge of the stone chamber to check, and picked up a broken dry bone from the ground, the broken place was unusually flat and smooth, it should have been cut by an extremely sharp thing in an instant.

But the palace lord searched for a long time and couldn't find the broken other half, so he put the dry bones in their original position, and let us go over to see that the section was just at the edge of the stone chamber.

"There should be a mechanism in this stone chamber." The palace lord told us to step back, and he picked up a stone and threw it into the stone chamber at random.

Bang dang.

As soon as the stone fell to the ground of the stone chamber, countless sharp guillotines fell from the top in an instant, and if someone stood inside, it would be cut to pieces in an instant.

After a few seconds, there was a boom, and the originally flat ground suddenly collapsed, and we realized that the entire square stone chamber was actually made of nine squares.

The stone chamber is not built on the foundation, but is built suspended in the air, supported by a mechanism in the middle, and below the stone chamber is a pit more than four meters deep, in which all sharp steel needles are erected, each one is as thick as a thumb, densely arranged, and falling from above is absolutely certain death.

There are still some bones penetrated by the steel needle, we probe to see, it is full of fragments of bones, no wonder this stone room is so clean, it turns out that the people who pass by above, once the mechanism is triggered, there must be no bones, this is simply a passage where no one survives.

Slipped to pieces by the guillotine on top, and then dropped into a pit covered with steel spikes below, the foolproof trap makes it impossible for anyone to get through.

Soon the hanging guillotine was retracted to the top, and it was impossible to find it without looking closely, and the ground that had fallen returned to its original appearance.

"What is this going to do?" Tian Ji asked.

This time, the palace lord couldn't answer, he squatted on the edge of the stone room, investigated for a long time, and when he got up, he still shook his head anxiously: "But all organs should have rules to follow, but I really can't figure out what the rules here are." ”

"Since it's a mechanism, there should always be a hint, otherwise there will be a steel stab above the guillotine, who can get by." Tian Ji said worriedly.

"No hints." I shook my head.

"Why?" Ling Zhihan asked in surprise.

"The owner of the Jieshi Golden Palace is Emperor Qin, and it is not difficult to see from the content of the stone tablet we found earlier that Emperor Qin does not want anyone to come here, he is the only one who can open this place, and he is also the only one who knows how to pass through these mechanisms." I replied with a heavy sigh.

"So no one can get through?" Tian Ji frowned, raised his hand and pointed to the corpse on the opposite side of the stone room. "That's not right, since there are bones on the other side, it means that hundreds of years ago, the Japanese and Jinyi guards have passed, how did they do it?"

"I haven't figured it out either, such a foolproof mechanism, it stands to reason that there shouldn't be any mistakes, unless someone knows the rules, no way can be passed, I can't crack the mechanism here......" Gong Jue said anxiously. How did they do it? ”

"There are black and white markings on the stone chamber." Akai Yoshitaka said, standing on the edge of the stone chamber. "Maybe it's a hint."

The mark that Akai Yoshitaka refers to is actually black and white dots, and the stone chamber is divided into nine squares of the same size, each with a different black or white dot.

The three squares in front of us, from left to right, are each engraved with the numbers eight, one, and six.

"This is the nine-square grid!" Ling Zhihan recognized it at a glance. "The nine-square grid is Luoshu, and these dots with different numbers and colors are arranged in the center of wearing nine shoes, three on the left and seven on the right, two or four for the shoulder, eight six for the foot, and five in the center."

"Tell me something you can understand." Xie Tianhui scolded and asked in the back. "What the hell is this?"

"The nine-square grid is three horizontal and vertical rows, three numbers in each row, the first row is four, nine and two, the second row is three, five and seven, and the last row is the eight, one and six you see. I went back and explained to him.

The palace lord looked at the divided lattice on the ground with a solemn face, and said worriedly.

"The nine-square grid is particularly common in ancient times to be used as a mechanism, to get to the other side of the stone room, you must first pass through the nine-square grid in front of us, only from the correct grid will be safe and sound, otherwise it will trigger the mechanism, but the problem is that there are too many changes in the array of the nine-square grid, without any prompt, not to mention the deadly mechanisms inside, even if you try it next to each other, it can't be tried out in a year and a half."

"After talking for a long time, there's just no way to get over." Xie Tianhui seemed to be very hostile to Gong Jue from the very beginning, and after scolding, he sat down in the corner of the stone wall. "A bunch of waste, you know how to delay Lao Tzu's time."

"You have the ability, you can go over and see for yourself." Tian Ji said indignantly.

"I'll go over ......," Xie Tianhui sneered. Then what am I still taking you for, I knew you were so useless, I might as well send you to feed the fish. ”

Gong Jue didn't get angry, we have no way to retreat now, the only chance to survive is to find another exit in the Jieshi Golden Palace, he didn't pay attention to Xie Tianhui at all, and said to us: "Rest here first, since someone can pass, there should be a way, they can crack the mechanism here, I should be able too." ”
