Perhaps it was something in his mind, or perhaps it was the inscription carved by Yuechengzi. Anyway, when Yang Jing looked at the dark cave again, he felt that the cave was like a devil with a huge mouth opened, sneering at him.

Yang Jing shook his head and began to take off his equipment. "Sisters and sisters, when people die, birds will rise, and even the phoenix will rise! For the sake of passing on the national seal, we must fight! Come on!"

At this time, he was still wearing a diving suit and carrying a high-pressure gas tank, and he was no more clumsy than an emperor penguin on the shore. If he wore this suit and entered this cave full of traps, he would definitely make things difficult for himself.

Although the air in the cave was still unaffordable, it was no problem to take off the diving suit, take off the compressed gas cylinder and put on a set of smart oxygen supply equipment. There were plenty of gas masks and high-pressure gas cylinders in the storage space, all specially prepared for such an unbreathable situation, and they were all high-end products bought by Yang Jing in the United States.

It was like a high-pressure gas cylinder as big as a 2.5L Sprite bottle, which was enough for Yang Jing to breathe for more than two hours. It was professional and high-stakes adventure equipment.

After holding his breath and changing into a new set of expedition gear, Yang Jing was finally able to go into battle completely lightly.

However, Yang Jing did not act in a hurry. Instead, he looked at the stone tablet again, then brushed his left hand across the stone tablet, and the stone tablet suddenly disappeared.

This stone tablet is a cultural relic with a thousand-year history after all. The most important thing is that it is an inscription with extremely rare extinct characters engraved on it. It will be a treasure if taken back.

In line with the principle that a thief never leaves empty-handed, such a treasure must not be left behind.

The most important thing is that this stone tablet is important physical evidence to prove the whereabouts of the imperial seal, so it cannot be let go.

After putting away the stone tablet, Yang Jing shook his neck and waist, and shook his arms and legs, then slowly walked into the cave.

The diving lights on his body were also replaced with high-energy spotlights, one on the forehead and one on the left shoulder to illuminate the front, and one on the right shoulder to illuminate the back. With these three high-energy spotlights, Yang Jing could see things within a range of more than 20 meters in front and behind in a completely dark environment.

When he was outside just now, Yang Jing did not shine directly into the cave. Now after walking into the cave, he found that the cave turned an almost ninety-degree right angle just less than five meters forward.

After turning the corner, the cave suddenly became much larger, both in height and width. If the previous cave could only allow people to pass through, then this cave was large enough for a truck to pass through.

Yang Jing looked at the rock wall and it was obvious that this section of the cave was not artificially excavated, but was also formed naturally. Apart from sighing at the uncanny workmanship of nature, Yang Jing really couldn't think of any other words to describe it.

But when he got here, Yang Jing immediately became more worried. Because although the rock wall of this cave was formed by nature, the ground was obviously not formed by nature. Because although the ground here is not very flat, if you look closely, you can still find that the ups and downs of the ground here have a certain regularity.

"Whenever there is three, go left one; when there is six, retreat two; when there is nine, move forward one, and pass the trap." Yang Jing still remembered the meaning of the words engraved on the stone tablet. He did not doubt that Yue Chengzi was making trouble. After all, this was engraved on the stone tablet by Yue Chengzi using the extermination script.

That is an obscene language. Even in the modern era of information explosion, there are only a few hundred people among the 1.4 billion people in China who can understand it. Not to mention in the distant Post-Tang Dynasty, there were absolutely only a handful of people in the world who could understand it.

Yue Chengzi used this method of writing to carve the mechanism, so he didn't worry at all that anyone could understand this kind of writing, so he didn't need to write randomly. After all, this also involved whether his descendants could successfully get the treasure at the end of the cave.

With the help of the bright light, Yang Jing looked at the ground carefully, muttering the key to passing the level.

This section of the cave is about thirty meters long and four meters wide. According to the ancient calculation of the length of a "step", this thirty-meter-long cave is about forty steps. Yang Jing couldn't see clearly at a distance, but he could see clearly within twenty meters, that is, within the range of thirty steps.

So, it didn't take Yang Jing long to find a pattern within the range of thirty steps.

Yang Jing discovered that although the ground in this section of the cave was uneven, he could still find a way if he followed the tricks carved by Yue Chengzi to look for the patterns.

It is like the ground is uneven, but if you look for it according to the tricks carved by Yuechengzi, you can see that some bulges are completely in line with the rules. Just like starting from the rightmost side of this section of the cave, if you calculate it based on a step of about 75 centimeters, then there is a bulge on the ground for three consecutive steps.

After three steps, there is no bump in front, but one step to the left of the last bump, there is another inconspicuous bump. Then, counting from this bump, there are bumps for six steps forward, and to the left and back of the sixth bump, there are two more bumps...

Obviously, these bumps on the ground are in complete accordance with the rules engraved on the stone tablet.

If it weren't for the tip, Yang Jing would never have thought that these protrusions were places for people to stay, and they were also the only places to stay in this cave.

If that's the case, then it must be clear that only by following these bumps can we successfully pass the trap in this first level.
