Seeing that Chen Si really didn't anticipate his own share, Gu Feng was anxious, and hurriedly said: "When I get underwater, only I understand mechanics, if you have any questions, it's a good thing to have me to help you with details, not to mention that I'm not so weak, there are so many people, safety can be guaranteed!" Gu Fengchun's reason sounds quite reasonable at first glance. But Gu Fengchun also knew that Chen Si's own attainments in organ science were already like grandmasters, and a rookie like himself who had just started didn't have many opportunities to help.

In fact, Gu Fengchun also has another advantage that he has not said, that is, he is in the water, his vision will not be disturbed, and he can clearly see things near and far. This provides greater assurance of safety for all. It's just that there are a lot of people, and he doesn't want to expose his unique ability.

Chen Si listened to Gu Fengchun's words, pondered for a moment, then nodded, and said, "Okay, you also come down, but if there is anything to do, you can quickly surface and escape." Chen Si's voice was very serious.

"Got it." The ancient style is true. Chen Si wasted no time, and immediately jumped into the water and dived down. He was followed closely by Soren Gyatso and Tang Maiqiu, and only the merman was the last to enter the water, his physical strength was exhausted, and he needed to breathe a sigh of relief.

After Gu Fengchun dived into the water, he found that the bottom of the water was even more turbid than he imagined. The surface layer has a mixture of blood and water, which greatly interferes with the vision. Only after diving seven or eight meters did the eyesight get rid of the interference, but at this time, the water had completely fallen into pitch black, except for Gu Fengchun and the merman, everyone else only relied on the lights on the waterproof miner's lamp. And this miner's lamp can only faintly illuminate the place seven or eight meters in front of it under the water, and anything farther away has become a touch of color.

The merman's tail didn't know when it changed again, and it was struggling to swim to the front, leading everyone forward. Chen Si followed closely behind him, and Chen Si was on the left and right of Gu Fengchun and Soren Gyatso. Behind the palace is Tang Maiqiu. Only when his own people are behind him, Chen Si can rest assured.

Gu Fengchun looked around and found a huge white turbidity current tumbling in front of him. He knew that it must be a column of water formed by a waterfall that came down from above. If you get caught up in this water column, it's not a joke. And Gu Fengchun, who has keen eyesight, unexpectedly found that in the center of the girl's water column, there seemed to be something similar to a waterwheel spinning rapidly.

"Then there's the entrance." The merman turned around and gestured to everyone. He watched his surroundings vigilantly, for fear of the sudden appearance of the Ceratosaurus. Chen Si nodded, dived a little closer, and saw the true face of this underwater mechanism.

Gu Fengchun's eyes also widened, for fear of missing every detail of this mechanism.

In the center of the stream, what looked like a waterwheel, was actually a simple turbine cast in bronze, and when the current hit, it was able to spin quickly and drive the mechanism below. Gu Fengchun clearly saw that this turbine was fixed with a copper pillar thicker than his thigh, which was simple and solid. These pillars are covered with spikes like maces, and it seems that they were specially made to prevent human destruction. Moreover, these spikes are also plated with antioxidant metal, and there is no oxidation on the surface. If you want to destroy these big copper pillars, these spikes are a big problem.

The crowd continued to dive. As they dived down, the crowd slowly approached the cliff of the waterfall, revealing the entirety of the mechanism. Sure enough, as the merman described, the whole mechanism was composed of countless wheel teeth, tightly leaning on the underwater rock wall, and two round wheels similar to windmills were spinning rapidly. The water is stirred up by these two runners to create a small whirlpool, and if you get too close, you are likely to be sucked into the whirlpool and stirred into pieces. The other parts of the two turbines that are fixed around them also seem to be equipped with bearings, and the surface is covered with spikes twenty or thirty centimeters long, constantly rotating, and if they get closer, they can also cause life-destroying consequences. Just behind this ancient and evil mechanism, a hole filled with running water appeared in front of everyone. Gu Fengchun knew that that was the way forward.

Gu Fengchun and Chen glanced at each other. They all know that such an agency cannot be destroyed by relying on the equipment they currently have.

"It's a big problem." Chen Si let out a long sigh through the communicator.

Gu Fengchun thought so. He thought for a moment and said: "Chen Si, do you say that there will be any device here that can control the mechanism, we are not the first people to come here, as early as more than two thousand years ago, Xu Fu transported Jiuding here, if there is no control device, then he will definitely find a way to destroy this mechanism!" However, the mechanism has been intact so far, which means that he used the mechanism device to stop the operation of the mechanism here. Gu Fengchun said confidently.

A word to wake up the dreamer. Chen Siru was enlightened, and he suddenly came to his senses. Before, his thoughts had been on how to destroy the mechanism. Because in his thinking, using the waterfall as a power source, it is impossible to stop the operation of the mechanism except to destroy the power source or these mechanisms. But Gu Fengchun's words made him suddenly wake up: Since Xu Fu can enter it without destroying this mechanism, it means that this place must be controllable!

Chen Si sighed and said, "What you said is good! That's how it should be! We're going to find out where the control of this mechanism lurks! Chen Si's tone was already a little excited.

"Watch your back!" Gu Fengchun suddenly found that the horned dragon was rushing out not far behind Chen Si and rushed towards Chen Si's position. The speed of this animal in the water was very fast, and it was only less than ten meters away from Chen Si in an instant.

"Bastard thing!" Chen Si hurriedly floated up, flicked the hand-held machine gun in his hand, and fired fiercely at the horned dragon. Gu Fengchun and the others saw that the situation was not good, and they also quickly floated to the water. In the water, the speed and power of the hand-held machine gun, as well as the firing track, showed certain restrictions and deviations, and although the bullet hit the ceratosaurus, the damage caused was not serious. The horned dragon seemed to recognize that Chen Si was the enemy who had injured it, and he didn't care about the trouble of others, so he rushed towards Chen Si!
