Merham threw a few pieces of bronze mesh into the pipe, then took out a night pearl and threw it in.

With the sound of "da-da-da", the beads kept rolling into the depths, and also reflected the scene in the depths of the pipe, and there was no other abnormality and no peculiar smell wafting out of the mud and moss that had grown after being soaked in water for many years.

"It should be safe, let's go inside." Mo Xian said and was about to bend down to go in, but Cheng Qixue stopped him,

"Wait."

Mo Xian and Mo Zhi looked back at Cheng Qixue suspiciously, and saw Cheng Qixue put on the gas mask that he had taken off because he was swimming in the water before, and then said, "Just in case." ”

"Yes." The other two were also in favor, and each wore a gas mask.

Then the three of them crawled along the pipeline to the depths, Mo Xian took the lead with the Night Pearl in front, Cheng Qixue was in the center, and Mo Zhiyu behind the palace was to get rid of the weeds outside, erasing the traces of their fiddling before following into the pipe.

The space in the pipe was very narrow at first, but when they crawled for more than ten meters, the space suddenly became larger, and they came to an underground stone chamber.

Just in case, several people gathered up some large rocks around them and blocked the exit together, disguised as a kind of landslide, and then continued to march.

The place they were in now looked like they were in a sewage system, with a lot of bronze pipes winding along the rock wall of the tunnel, finally converging in the stone chamber they were, and then slapping at the pipe they had just climbed into.

"Wow, you Heavenly Sword Mountain made this kind of thing more than two thousand years ago? I've only seen this thing in the Yun family, and I got it after that girl became the head of the family. Cheng Qixue sighed sincerely,

"But it's better than the one we're using now. I was going to get a set to Rongzhou, and the girl agreed, but she has been very busy, and I can't understand the set of drawings she gave, and I can't understand the craftsmen and craftsmen who found them, so I haven't dragged it out. ”

Cheng Qixue said that "that girl" is of course Yun Shi, she has always called Yun Shi "girl", and only occasionally said "your daughter-in-law" to Mo Zhiyu.

Mo Zhiyu didn't doubt this, because Yun Shi was a person with the same memory of that world as he was, and it was normal for him to have such a system. And the person who built this place is, of course, another person who has the memory of that world—another himself.

Since he had come to a familiar place, the exit should be much the same, so he said: "This should be a sedimentation tank, the original appearance must be larger than the first one, but the place we are stepping on has been filled with garbage that has not been cleaned for many years." ”

As he spoke, he jumped on the ground, shaking the stagnant water below, and then he said, "You see, the soil here is still loose and not petrified, which means that this system has been used for two thousand years. Then the entrance to the system must still be there. ”

"That exit must be the dungeon that leads to the Shaman's Temple!" Cheng Qixue said happily, and then looked left and right, and saw the ladder on the rock wall next to him at a glance.

It's just that when she ran over and pulled it, the bronze ladder scattered "with a bang", and the remaining half of the hanging on the wall was estimated to be impossible to climb. Cheng Qixue could only scold in a low voice: "! ”

"Don't worry, let's just jump on it with Yuan Li, this kind of pool has no cover, there must be a road on it." Mo Zhiyu said, and then took another Night Pearl from Merham.

Then he retreated from the rock wall, presumably to the center of the sedimentation tank. Then he threw the night pearl upwards with all his strength.

Then I heard a "pop", and the night pearl slammed into the darkness on the top, and shattered into two pieces on the spot, one fell back to the ground intact, and the other bounced somewhere high and did not fall, but only shone light on it.

"That's it, let's jump over there." Mo Zhiyu said very firmly, picked up the other half of the night pearl from the ground, and then rushed towards the rock wall in front of him, and rushed to the rock wall with the help of this distance, almost rushed to the top in one breath, and then kicked on the rock wall, and suddenly hung on the edge of a certain place in the sky.

Then he used his hands and feet together, and finally he was afraid, and the night pearl flashed three times above, indicating safety.

Mo Zhiyu has succeeded, and the other two people jumped quickly according to Mo Zhiyu's action just now, and they also came to the top.

When you get to the top, you finally look like you're entering a real tunnel, but it's still dark and damp, and it's very uncomfortable.

This time, the Ink Changer led the way with two closed Night Pearls in front of him, and said as he walked, "Let's follow these pipes and we will be able to find the entrance." ”

As he spoke, he also moved the Night Pearl to the left and right, focusing on illuminating the bronze pipes.

Mo Zhiyu's familiarity with this place did not surprise the two people next to him, because they thought that Mo Zhiyu would naturally be this kind of thing as Yun Shihui, so they didn't ask anything.

It's just that Cheng Qixue looked at the trend of these pipelines and became more and more puzzled: "This tunnel makes me feel that it should be from a relatively high place, but I have studied your ...... before." What a character......"

"Monhesleg." This time, Murham whispered a reminder behind her.

"Yes." Cheng Qixue replied to him a little impatiently, and then continued, "I have studied the map, this city is built against the foothills of Tianjian Mountain, and there is no such a big difference in height, these pipes are made like this, there shouldn't be any problems, right?" ”

"No," said Mo Zhiyu, "even if the water is raised from the bottom level, it is not impossible, because as long as there is water, there will be pressure, and when the pressure in the pipe reaches a certain point, the water will naturally look up under the action of pressure." That's right, look, we're going downhill. ”

He stopped at this time, so that the two people behind him also stopped in time, so that people could see that the road in front of him had been descending, and the slope was very strong, which made people very worried that this thing would flow back.

"It's too complicated." Cheng Qixue sincerely expressed her admiration.
