Thinking of this, Shen Lian didn't hesitate at all. He looked directly at the other instruments.

I saw that there was an iron rod on the large gears on the equipment, blocking the rotation of these gears.

Shen Lian said: "Take off all these iron rods."

When everyone heard this, they naturally did not hesitate.

They took action one after another and pulled away the iron rods that blocked the operation of other gears.

Soon, some harsh and tooth-piercing sounds were heard.

Those gears seemed to be breaking free from the shackles of rust and slowly began to rotate.

It was a little slow at first.

But gradually, the speed is getting faster and faster.

Finally, it was fixed on a frequency.

Looking at these rotating gears, Shen Lian was curious, what kind of power allowed them to be separated for so long and still keep running?

Shen Lian expressed his doubts to Fatty Zhang.

Fatty Zhang shook his head and said, "I have experienced some mausoleum agencies. Different agencies have different situations."

"And to be honest, the older the tomb is, the more broken its mechanisms are."

"Even if the design was very smart at the time, some problems will still occur after so many years."

"But there are indeed some institutions that are very powerful."

"And the power of these institutions..."

Fatty Zhang said: "I was once curious about the mechanism of a mausoleum, so I went to check it out. I found that the power of the mechanism of that mausoleum comes from the underground river where the tomb is located."

"Under that mausoleum, there is an underground river. The underground river has been flowing. The flowing water has become the driving force for the operation of the mechanism."

"So even after many years, as long as the water in the underground river does not dry up, the mechanism will not stop operating."

Shen Lian suddenly realized.

This really touched upon his blind spot.

Shen Lian was a detective in his previous life. Although a detective needs to know a lot of knowledge, organizational knowledge is not among them.

After all, in later generations, such mechanisms are almost invisible.

Fatty Zhang looked at the equipment in front of him and said: "I suspect that the power of the mechanism here may also be water flow. Because this underground palace is located in a mountain, there is probably mountain spring water in the mountain. The mountain spring water is constantly circulating and will not dry up easily. "

Shen Lian nodded slightly.

This guess is very reasonable.

Otherwise, Shen Lian couldn't think of any motivation that could last for thousands of years.

At this time, Shen Lian suddenly discovered that the frequency of the fingerprint rotation of a device was obviously different from just now.

The gear first slowed down for a moment, and then started to rotate rapidly.

Fatty Zhang saw Shen Lian looking at the gear, and he followed suit.

And when he saw the gears changing, Fatty Zhang suddenly said: "Someone else triggered the mechanism!"

"This is a sign that the mechanism is working!"

When Shen Lian heard this, his heart moved.

"The people from the Beidou Club are here!"

…………

Before half a stick of incense.

Go to the secret passage of the underground palace.

The Beidou Society and the others, led by Yinyuan and Yuheng, were walking down the steps.

After arriving at the location told by Shen Lian, it didn't take long for the entrance to the passage to be discovered.

After that, Yin Yuan and the others entered the secret passage.

All the way down, they didn't find anything unusual.

Originally, Yu Heng was still worried about meeting Shen Lian in the secret passage.

But as a result, there were no traces of Shen Lian and his companions walking along the way.

This made Yu Heng not sure whether Shen Lian had already come in or was following them.

"Stop!"

At this time, Yu Heng suddenly stopped the team.

The one-eyed Yinyuan looked at Yu Heng and asked, "What's wrong?"

Yu Heng looked at the steps in front and said, "There are water stains on the steps, but there are no water stains elsewhere."

"I suspect there may be some danger ahead."

"Maybe there is a mechanism."

Yu Heng made the same judgment as Fatty Zhang.

But when Yin Yuan heard this, he laughed.

He was very confident and said: "Don't worry, there will be no danger!"

"There were indeed mechanisms here, but now, those mechanisms won't move."

Hearing this, Yu Heng's eyes flashed slightly and he said, "How do you know?"

Yinyuan raised the corners of his lips and said, "Beichen told me."

"okay."

Yin Yuan took the lead and walked forward, saying: "Let's go, don't worry."

Naturally, no one would doubt Yin Yuan.

But Yuheng always felt that something was wrong.

But before he could finish thinking, he heard a click.

The steps under Yin Yuan's and the others suddenly sank.

at the same time---

Phew! Phew! Phew!

Countless arrows suddenly rushed out from all directions.

It’s too late to say it, but it will be soon!

Just after Yin Yuan led the Beidou Club members, they stepped onto the water-stained steps with a confident look.

The steps sank down.

The mechanism is activated directly!

In an instant, many arrows flew out from the stone walls on both sides and the stone wall above our head!

The tips of these arrows are sharp.

And very dark.

It looked like it was poisoned.

I just don’t know if this poison can still be effective after so many years.

But even if the poison has no effect, the sharp arrows are enough to make these people look good!

Yu Heng's footsteps stopped immediately.

She looked forward.

As for Yinyuan, his expression suddenly changed.

"how so!?"

"How could the mechanism be activated!"

Yin Yuan roared, drew out the sword from his waist, and cut off the arrow that was directed towards his face.

He yelled at the same time: "Quick, stay back."

Because the area of ​​​​the water damage is large, if you rush forward, it will only be more dangerous.

Therefore, he asked people to step back first.

But behind him, there were members of the Beidou Club who had just come with him.

And these members, because they trusted him, were not prepared or defensive at all.

When we suddenly encountered these dangers, we were unable to react in time.
To be continued...
