They are stepping on the ground, because they are carrying a heavy load, and the underwater flow is not as exaggerated as expected. They can move anything, and even walk in a standing posture. Of course, the water pressure is not small. Most people feel uncomfortable when they get to this kind of pressure. They are OK when they get there, and they can still adapt.

According to the plan, the two men moved separately. Although some underwater robots used water pressure guns to carry out basic cleaning before, some places still need people to see with their own eyes.

Those big fish stirred here for a long time yesterday, but Lin Mingyuan watched them. Their big bodies can go in, which means that if Lin Mingyuan finds the door, he can go down.

It seems that this is nonsense... It took Lin Mingyuan a few minutes to find the location of the three words. According to the southeast and northwest, the three words are located in the south of the huge door, which is the location of the gatehouse.

According to the pictures drawn by the underwater robot, it can be seen that this is a whole door, the opposite door. Lin Mingyuan kneels on the ground and judges the material of the door, feeling that it is like a copper door.

It's an opposite door. It should be two doors, but Lin Mingyuan didn't find the crack in the middle. At least in his eyes, it's two doors, but they fit perfectly.

The height of the door of a basketball court is wider than that of a basketball court. The length of a standard basketball court is 28 meters and the width is 15 meters, so the door is almost the same. It can be said that it is very tall. Even if the giant is three or four meters high, it is a little too high, isn't it?

I'm afraid it's not for giants. It's a giant more than ten meters tall!

Oh, thinking of this, Lin Mingyuan thinks it's possible. After all, the giant who lives here has already explained that he grazes here. It makes sense to combine these big fish which are too big to be understood by ordinary people.

Grazing place, maybe there are other guys?

When Lin Mingyuan thought of this, he reached for a piece of gravel and knocked on the huge door under him. There was a knock in his ear, which proved that it was really metal, and it was relatively hard, because the stone in his hand was broken after only a few knocks.

On the other side, Leng Jianfeng is also looking for the entrance. They are divided into two sides. He is in the north, which can be said to be under the door. On the door, lengjianfeng found some depressions, which are big depressions. They are on the door, about five or six meters long, and they are located at the bottom left of the door. After measuring, they are about four meters, as if they were cut by something sharp.

Soon he decided that it was cut by a sharp tool. Although I don't know how many years have passed, it looks like it was cut by sight.

Leng Jianfeng photographed the situation here, transmitted it to the shore, and called Lin Mingyuan. The situation here is somewhat special. According to Lin Mingyuan, this door was at least tens of thousands of years ago, thousands of years ago. At least there is modern human civilization. If it is tens of thousands of years or even longer, such a door is a miracle, Not to mention the brand new wound on the door.

Bronzes are easy to be oxidized, that is to say, rusted. So it's very exciting to find complete bronzes in archaeology. After all, it's really easy to be oxidized. It can rust a lot in a few years, not to mention tens or hundreds of years, or even thousands of years. It's a miracle that King Gou Jian's sword can be preserved for thousands of years without rust, As for those bronze chimes, this is especially true. These things can only be preserved under specific conditions, and more of them have been damaged in the long history.

The huge door in front of us lies on the river bed like this. I'm afraid no one knew its existence before. However, since it is exposed to the surface, it means that it has been exposed to the wind and sun for many years.

But look at it now, it is still intact, as if it was just cast, which makes people feel incredible.

Lin Mingyuan also came over and looked at the scene in front of him. He also thought it was incredible. Like Leng Jianfeng, he thought it was cut by a sharp weapon. However, it was obviously a knife that had been cut for a long time. It was still as if it had been cut by a new knife. This is very incredible.

With a gesture, Lin Mingyuan motioned to them to put down here and continue to search for the entrance to the door, or the way to open it. That day, when they were looking in the air, the seven big fish were head down and tail up, and they smashed the door open like they were rushing to the hard top. Now what? Hard top, too?

A few tons of big fish can push it open, but Lin Mingyuan thinks that he can't push it open. No matter how strong he is, he can't push things that need tens of tons of force.

Sometimes tonnage is a very important thing. Large tonnage means that the muscle volume is also large, so the strength is naturally large. On the contrary, no matter how big the strength of a small skinny person is, it may not be greater than that of a person who is more than twice his body weight.

Compared with big fish, Lin Mingyuan is too light, so he thinks it's a bit mysterious to open the door by himself. If he really needs to push it open, it's still a drama unless he gets a large ship, designs professional equipment, and uses mechanical force to push the door open.

Of course, it's just an idea. Lin Mingyuan thinks that the way to open the door is not brute force. Otherwise, those big fish can say that if they are giants, can they open the door by themselves? Obviously, this is a question mark.

So Lin Mingyuan thinks that there should be a way to enter this door on the ground, and this method needs two people to find out.

A safety signal was sent to the people on the ground, and the two continued to search.

On the shore, Xu Yanan and others are a little anxious. She sits in front of the monitor. There are several pictures on the monitor, including the video pictures of Lin Mingyuan and Leng Jianfeng, and the pictures transmitted by the underwater robot. At present, everything is normal, and the radar has not found any trace of the big fish. Moreover, for the sake of safety, the radar has been arranged for a certain distance upstream and downstream, Even if the big fish suddenly appears, it will take at least three or four minutes to get back to the door, which can give Lin Mingyuan and Leng Jianfeng a certain reaction time. After all, the water depth is not deep, and it only takes dozens of seconds to float up, so they can get to the shore in a short time when they get on the speedboat.

For now, it's safer to be on the shore.
