Back in the toilet, there were eight planks, all about four meters long and 40 to 50 centimeters wide.

Fortunately, there is an Ontario machete in his hand, although it can also be chopped if it is a sapper shovel, but the effect is not as real as a machete.

Hu Xiaodao originally intended to split in the toilet, and then thought that since the black snake didn't chase after him, there must be something to restrict them.

After moving the eight planks to a position about fifty meters away from the circular stone plate, and everything was done, Hu Xiaodao picked up a stone from the ground and threw it over.

"Shhh ~”

The disturbed black snakes ran out of the hole one after another, but they looked around blankly, apparently not finding where Hu Xiaodao was.

Hu Xiaodao suddenly felt funny, and then picked up another stone and threw it over.

This time, the black snakes seemed to be completely enraged, and they flew down in a swarm, and the total number of snakes was about five hundred.

But when the catapult is twenty meters away from the grinding plate, it stops and wanders around, refusing to take a step forward.

"Hahaha, you brutes, you only have this means!"

After understanding the range of activities of the black snake, Hu Xiaodao immediately had the courage to move the wood to a distance of twenty-five meters and began to chop, picking up stones and smashing the black snake as if he was provocative.

However, the black snake seemed to be pulled by something, and it couldn't leave the stone plate for half a step.

After a while, Hu Xiaodao lit the fire, and when the black snake saw the fire, it all slipped into the holes in the middle of the stone plate, and did not dare to approach at all.

Hu Xiaodao rushed into the twenty-meter forbidden area with a torch in his hand, but the black snake still disappeared, so he picked up the stone and threw it again, and the black snake only poked out its head, and when they saw the fire, they retracted into the hole and never showed their heads again.

"That's going to do it, burn you brutes! ~”

However, Hu Xiaodao is not completely burned, because there is not enough wood, so you can only take down the equipment with a torch first!

When climbing up, the torches flickered, and those black snakes also followed the beating rhythm of the flames in and out, as if as long as the torch was extinguished, they would instantly attack and bite Hu Xiaodao.

Carefully climbing up to the sixth layer, Hu Xiaodao took a closer look, and there were no small holes on the seventh layer, so there was no need to worry about the appearance of a black snake.

He looked back at the black snake cowering in the hole behind him, and reached out to throw the items on the seventh floor into his backpack.

Without paying attention, his fingers slid the small round ball on the stone plate.

This small ball Hu Xiaodao has seen before, similar to the round ball in the mouth of the Shuanglong in the ancient Chinese carving, Hu Xiaodao has always thought it was decorative.

Now, after fiddling with his fingers, the stone cave on the fourth floor suddenly disappeared.

Hu Xiaodao turned on the miner's lamp, and when he looked carefully, the small hole in the stone plate really disappeared, as if it had never existed.

Hu Xiaodao turned around and looked at the seventh layer of stone plates, and sure enough, there were five other round balls, placed in the shape of six-pointed stars.

With Hu Xiaodao's ingenuity, he instantly understood what kind of stone plate this was, this was an altar.

And the sixth underground layer is a class, but the seventh layer can control the life and death of the people on the six floors below, so there will be a black snake.

As for why the black snake couldn't be twenty meters away from the altar, Hu Xiaodao's idea was that the ancients used some secret method to control the black snake within a range of twenty meters, otherwise the black snake would not exist for thousands of years.

What makes Hu Xiaodao strange is what these black snakes rely on to survive, but when he thinks about the mice in the distance, he understands that there are many black snakes here, and there are also many rats, so there is no need to worry about food sources.

After roughly understanding, although Hu Xiaodao was not a person of that era, he firmly believed that the cause and effect of the incident was like this, so he did not hesitate at the moment and quickly dialed the other five balls.

When he dialed it, Hu Xiaodao found that the ball was two-colored, the black side represented that the black snake would come out, and the white side turned up, and the mechanism would control the appearance of stone slabs on each layer to block the black snake hole.

These things have existed for tens of thousands of years, and although Hu Xiaodao can't bear it, he won't joke with his life.

After completely closing, Hu Xiaodao looked up and down a few more times to make sure that there was nothing missing, and then he put down the burning torch in his hand and concentrated on putting on his clothes and equipment.

After everything was dressed, Hu Xiaodao's eyes fell on the six-pointed star pattern on the surface of the seventh-layer altar.

According to this pattern, Hu Xiaodao thought that there must be other mechanisms, but he didn't know it.

Although standing on the sixth floor can fully see the seventh floor, which is only 1.2 meters high, the vision is definitely not as clear as standing on the seventh floor.

Hu Xiaodao climbed to the seventh layer, and the soles of his feet tried to bypass the clusters and grooves of the six-pointed star as much as possible, and only walked to the empty place in the middle to the middle.

In the middle is a small circular hole, from which all the grooves extend to form a six-pointed star pattern with a golden ratio.

Hu Xiaodao lowered his head, looked at Xiao Kong thoughtfully, and re-filtered all the images in his mind after he came in. Still don't have a clue.

Hu Xiaodao simply didn't want to, all along, the six-pointed star pattern represents the Jews, Hu Xiaodao doesn't know what the world was like thousands of years ago, but it must have nothing to do with the Jews.

However, when Hu Xiaodao decided to leave, he accidentally found that there were six square-shaped things next to the six-pointed star, which was next to the ball, with delicate grooves, and it was obvious that the six corners of the six-pointed star in later generations were sharp, and there was no such thing next to it.

If a person's curiosity comes up, he may lose his life, but he may also lead to Rome.

Hu Xiaodao is currently in this state, he inadvertently closed the black snake's cave mechanism, and then found this rectangular groove with a diameter of only about ten centimeters next to it, although he didn't know what to do, but Hu Xiaodao still squatted there to study.

This may be used for water, and after having this idea, Hu Xiaodao spat at the mouthful, and the stone trough did not have any reaction.

Then Hu Xiaodao got some sparks and threw them inside, but the stone trough still had no reaction.

In the end, Hu Xiaodao had no choice but to give up, and stood up with the Ontario machete and prepared to find another way.

At this time, the whole altar suddenly shook. Hu Xiaodao looked down nervously, and it turned out that the tip of the knife happened to be against the rectangular stone trough, and the stone trough actually sank a little.

Hu Xiaodao was overjoyed, stood up and pressed the stone groove with his toes, and pulled out the sapper shovel from behind with one hand, paying full attention to the surrounding situation.

It turned out that it was not the altar moving, but that a stone block on the wall not far away was gradually pulled up by the mechanism, and it was raised by about 30 centimeters.
