Chen Jian kept walking forward and silently calculating his steps to calculate how long this long cliff stone platform was.

Finally, when Chen Jian walked about two hundred steps, or 150 meters away, less than two hundred meters away, this long cliff stone platform came to an end.

Chen Jian was right before. This long cliff stone platform is indeed connected to the mountain, and it is a vertical cliff, which extends such a stone platform from this cliff.

The magical skills of nature are truly unimaginable.

The most important thing is that there is a stone gate where the terminal of the stone platform is connected to the cliff. This stone gate is about four meters high and two meters wide.

Chen Jian walked to the stone door and reached out to knock on the stone door. But at this time, twenty meters deep under the water, under the influence of water pressure, even if Chen Jian was in the form of a wild beast, he used a lot of strength and could not knock on any different feelings.

Since he could not knock, Chen Jian could only change his way and reach out to touch the surroundings of the stone gate.

Then, Chen Jian made a floating gesture to No. 2 and started floating first.

It didn't take long before Chen Jian and No. 2 floated to the surface together.

In fact, Chen Jian and No. 2 still did not reach the limit of holding their breath at this time and could continue to move underwater, but it was meaningless to continue to move underwater at this time.

However, when floating, Chen Jian and No. 2 did not float directly to the water surface, but had to change the direction before approaching the water surface, and changed to a straight line underwater. After moving forward for a distance in a straight line and seeing a bright light above your head, they continued to float again.

Because Chen Jian and No. 2 had to do this, floating straight along the cliff where the stone gate was located, and floating up to a certain area, the rock wall extends out above the head. They can only move forward in a straight line and leave the area where the rock wall can continue to float.

After floating to the surface, Chen Jian said: "From the long-term plan."

After Chen Jian said this, he swam towards the shore where they went into the water first. No. 2 followed closely and swam towards the shore.

Chen Jian came back with No. 2 and didn't worry about it so much, so he just got out of the water. Anyway, Chen Jian was walking in front and couldn't see No. 2.

As for No. 2, Chen Jian was too lazy to care about so much when he could see Chen Jian's back. After getting ashore, he immediately put on his own clothes and walked to one side to sit down.

No. 2 also quickly put on his clothes and came to Chen Jian to sit down.

"What's going on with that stone gate?" No. 2 asked immediately.

"Let's not talk about this for now, let's talk about the situation of this lake!" Chen Jian pointed to the lake and said, "Although the lake surface of this lake looks round, it is not actually the case."

No. 2 nodded and said, "When we floated up, the rock wall that extended was there!"

No. 2 said, raised his hand and pointed at the place where they had just floated up, which was where the rock wall was protruding, and said, "Now it is the shore of this lake. Combined with the situation we see underwater, the situation underwater is similar to the shape of an English letter!"

"Caps d!" Chen Jian nodded and said, "The cliff where the stone gate is located is actually the vertical position of the capital d, but the entire lake surface looks like a circle because of the cliffs extending above. The position I am now at is the middle point of the arc of the capital d!"

No. 2 nodded silently. In other words, the underwater stone gate was directly opposite to Chen Jian and No. 2 at this time, opposite the lake.

"There is no difference for us where to get into the water." No. 2 said at this time: "Anyway, we need to switch shapes, otherwise, if the depth is too deep, we won't have enough time to hold our breath."

Chen Jian looked at the lake and said, "I think this lake was not so deep. The long stone platform nearly 200 meters extending from the cliff had certain traces of manual digging and polishing, which meant that it should have been a road, and it was a road exposed on the lake. If you want to go to the stone gate, you need to row from the lake and walk on the stone platform!"

"I agree with your point of view." No. 2 nodded and said, "If you don't explain this way, there is no need for manual processing of the extended stone platform. However, you don't know what era you mentioned!"

Chen Jian nodded silently, and the specific age was naturally impossible to determine.

"What's going on in the stone gate?" No. 2 asked again.

Chen Jian shook his head slowly and said, "You also saw that I wanted to knock on the stone door hard to determine whether it was empty behind. To be precise, whether there was water. After all, the stone door is underwater now, but the water pressure is too high, so there is no force at all. The resistance is too great. I finally touched the stone door around and checked the sealing of the stone door. This stone door is not a swing stone door, but a recessed one. It should be opened by moving horizontally. Such a door has much better sealing than a swing door. Moreover, if it is a swing door, you basically don't need to consider it. There must be water behind the stone door, because the water pressure will squeeze the door open!"

"There must be a mechanism to open the stone gate." No. 2 said at this time.

"This is for sure." Chen Jian heard No. 2's words and understood what No. 2 meant, and wanted to go down again and find the mechanism to open the stone gate.

However, Chen Jian held a negative view on this and said: "I don't know what era the stone gate is from, and the mechanism has gone through many years. I am not sure whether it can open the stone gate. Moreover, the stone gate is located about twenty meters under the water, and the water pressure is very high. Even if the mechanism is still effective, I don't know whether it can be opened normally under the squeeze of water pressure!"

Hearing Chen Jian's words, No. 2 nodded and said, "If we were right, the stone gate was exposed on the water at the beginning of its construction. Later, I don't know why, whether it was a terrain change, or the rain became heavier, which flooded the stone gate. In short, the design of the stone gate was not directly designed underwater at the beginning."

No. 2 said this and looked at Chen Jian and continued: "Since you don't have to consider the way the mechanism is turned on, then we can directly blow up the stone door!"

"How to explode?" Chen Jian asked with a frown.

"Although the ten-person team has no bullets, there are other equipment. Those equipment are distributed to them by me. I have also learned some knowledge in this area. You can use those equipment to make a directional blast!" No. 2 looked at Chen Jian and said, "You just need to tell me clearly whether you want to go to the back of the stone gate to investigate!"
