The further you go in, the higher the strength of the mechanism. The poisonous needle and the dark arrow wiped out the poison that Madoka couldn't bear, and it also has the effect of piercing armor.

After proceeding cautiously for fifteen minutes, he finally walked out of the cave, and the front suddenly became clear.

This is a huge space almost hollowed out in the mountainside, full of Song Dynasty-style buildings, located in an orderly manner, and the streets are well-organized, just like an ancient small city.

There are also well-developed water supply, ventilation and lighting systems in the small town. There are several large water pools on the edge of the city, and beside the water pools are rows of waterwheels and several water houses.

The water room will divert part of the clean water into the artificially dug river channel for daily water use by the disciples.

On the top of the tall cave is a huge crystal disc with a diameter of about sixty meters. It focuses the light outside the mountain and brings light to this underground city.

Layers of corridors are built on the stone wall, spiraling upwards, leading to the top of the cave. Every ten meters in the corridors, there is a hole with a diameter of 2 meters, which is initially estimated to be a ventilation system.

It's just that I didn't hear the sound of the exhaust fan. It may be because it has been abandoned for too long. The living system here has stopped working, or the ventilation method of the ancients has opened holes.

"It's really spectacular. This should be Mozong's headquarters. If it wasn't damaged, it would be even more spectacular." Sun Miaomiao sighed with emotion.

Yes, it's all broken.

The small town in the Song Dynasty seems to have been violently demolished, and most of the buildings collapsed. The outer areas are fine, and many of them remain the same, but the further inward, the more serious the ruins.

There should have been an earth-shattering battle in the city center that year.

The layers of corridors on the top of the grotto are also fragmented, broken one by one, and the iron cables hanging from the corridors should have pedals, wooden barrels, etc., for objects to rise and fall. At this time, it also became a string of different lengths.

In addition, looking at the traces on the ground, there should have been many strange mechanisms here, because everyone in the team saw something similar to railroad tracks.

But now here are the ruins.

While Sun Miaomiao was feeling emotional, Zhao Chenghuang, Zhang Yuanqing, and Guan Ya each used the spirit devouring and insight skills to observe the breath of resentful spirits and living people.

"There is no breath of resentful spirits." Zhang Yuanqing said.

"In the central area of ??the city, the breath of a living person has been detected." Guan Ya found out, he looked at her boyfriend and said, "Give me a kick."

Zhang Yuanqing understood, bent down and lunged, exposing his knees.

Guan Ya took a few steps back, trotted and sprinted, and stepped on Zhang Yuanqing's knee, her vigorous and tall figure soared into the air, leaping more than ten meters high.

Zhang Yuanqing's knee shattered with a "click".

This kick was somewhat personal. Zhang Yuanqing grinned and hugged Sun Miaomiao beside him: "Help me, give me a hand."

At this juncture, he dared not touch Xiaoyuan.

Sun Miaomiao resisted a few times, then took the initiative to support his waist, and stopped his waist from being used as a crutch.

Xiaoyuan glanced at Sun Miaomiao, looked at Zhang Yuanqing and said, "May I let this little sister help you too?"

She was referring to Ryo Asano.

"Auntie Xiaoyuan, don't be so cynical that Guan Ya has come down."

Guan Ya fell to the ground with a "slap", speaking extremely fast:

"There is an open space in the center of the city, about 1.2 kilometers away from us. There is a mecha in the open space. There are vital signs inside the mecha. Other than that, no other enemies have been detected."

"Mecha? Are you sure you are talking about mecha? 1.2 kilometers, can you see it clearly?" Brother Hongji expressed disbelief, but was also very interested: "What style is it? It's tall or a Transformer." JrNovels.com
