In front of the Overlord is a huge, unfathomable huge hole, not an ordinary big hole.

Standing on this huge edge, Ba looked at it carefully and thought that this huge hole was extraordinary.

"Master, Master, look at this huge hole."

At this moment, Liu Yong has gotten off work and is in his big villa worth hundreds of millions. Now, he usually lives here.

The large villa worth hundreds of millions is extremely luxurious, with all kinds of equipment, warm in winter and cool in summer, living here is simply a pleasure.

All kinds of servants are basically complete, such as security personnel, gardeners, cleaning personnel, chefs, etc., and a total of more than a dozen people serve Liu Yong.

Of course, Li Changle often comes here to stay for a while. It is summer vacation, so she basically lives here.

Liu Yong was in the study room, and the sound of a king sounded in his mind. He immediately opened the pet panel and opened the first-party vision.

Suddenly, Liu Yong saw the Overlord.

It is known that the Overlord is located at the seabed more than 4,000 meters deep, and within a radius of 1,000 meters, this area is extremely flat.

What surprised Liu Yong was that there was a huge circular hole in front of the Overlord.

This huge hole is vertically downward and looks bottomless. It is huge and can have a diameter of more than 1 kilometer.

In this way, a huge vertical and unfathomable cave suddenly appeared on the underwater plain, which was shocking enough.

Liu Yong was very shocked that this huge hole was actually a standard circle, very standard, as if it was drawn with a quantity rule.

Yes, the feeling is the same standard as the measurement code!

Is this natural or artificial?

If it is natural, then I really want to admire the magic of nature. It actually has such a huge hole, a standard round shape.

What if it is artificial?

That's so scary. How high is the scientific and technological level of creating such a standard, vertically downward hole on the seabed with a water depth of more than 4,000 meters.

As far as Liu Yong knows, humans' current technological level seems to have no such ability.

No matter whether it is formed naturally or artificially, you will know it after you go in and take a look.

In the third party's vision, Liu Yong did not see any danger. There were some strange marine creatures, but compared to the huge overlords, they were all little guys and could not threaten overlords.

"Master, such a huge hole looks so strange."

Liu Yong said: "Do you want to go in and take a look?"

The overlord said: "Of course, if there is something delicious in this huge cave, that would be great."

Liu Yong despises it a little bit, a foodie, a typical foodie thinking. The first thing he thinks about is whether there is something delicious in this huge hole.

The Overlord was thinking about the delicious food in his heart. He began to enter this huge cave and slowly swam towards the bottom, and the depth gradually increased.

Liu Yong, through a third-party perspective, pays close attention to all situations and pays special attention to the walls of this huge cave.

"Bully, slow down, don't be anxious."

After listening to Liu Yong's instructions, the Overlord went down even slower and slowly headed towards the bottom of the cave.

Liu Yong noticed that this giant hole has always been very regular, not only its opening is a standard circle, but also a standard circle inside the hole.

The Overlord had dived down hundreds of meters deep in the huge cave. The cave had always been a standard round shape. Although the cave walls were not very smooth, they were still flat.

"Overlord, stop for the time being, I want to see the situation of the cave wall."

The overlord stopped as he said, and Liu Yong carefully checked the situation of the cave wall.

The giant hole has always been a standard circle, and it is standard vertical downward, without any bending or tilting. Liu Yong even more doubted that this is an artificial product, rather than a natural one.

If it is natural, it is impossible to be so standard and standardized, it is impossible to always be a standard circle, nor can it be a standard vertical downward.

The Overlord stopped, and Liu Yong carefully checked the situation of the cave wall through a third-party vision. Unfortunately, although the cave wall is relatively flat, there is no trace of artificiality.

Could it be that this huge cave has been formed for thousands of years, or even tens of thousands of years, and the traces of artificiality have long disappeared.

This guess came out in my mind, and Liu Yong was shocked. Thousands of years ago, or tens of thousands of years, was it a prehistoric civilization or an alien civilization?

Through a third-party perspective, Liu Yong checked the cave wall for a long time and basically confirmed that this huge cave was definitely not formed recently and looked very old.

Compared to natural formation, Liu Yong hopes that it is a prehistoric civilization or an alien civilization.

"Overlord, keep going down until your limit."

"Okay, master."

"Slower speed." Liu Yong reminded. "I think this huge hole is a little abnormal, and you can't be wrong if you are careful."

The Overlord continued to move downstream, not fast. Liu Yong was worried about something in the cave, and the third party's vision was always open, but the giant cave seemed to be empty. Except for the sea water, after reaching a certain depth, there were no glowing marine creatures.

Continue down, the Overlord exceeds a depth of 6,000 meters.

At this depth position, it began to feel the pressure of the sea water, but did not give up and continued to move down.

6800 meters is the ultimate depth that the Overlord can reach. It feels like staying at such a depth for a few minutes is the limit, and it feels like you are about to be flattened.

"Master, I can't go down again, the pressure on the sea water is too great."

Liu Yong looked at the depth on the pet panel and was quite satisfied. The 800 tons of Ba Wang can reach a depth of 6,800 meters.

The only regret is that this huge hole is still bottomless. The Overlord is now at 6,800 meters, plus the third-party vision 1,000 meters.

In other words, Liu Yong could see a depth of 7,800 meters through a third-party vision, but he still didn't see the bottom of the giant hole, so he didn't know how deep it was.

Could it be that this is simply a bottomless pit!

Since the Overlord could not go any further and had not found anything, Liu Yong simply said: "Obbot, let's go back, this huge hole is too deep."

The Overlord felt relieved. It really couldn't stay for a few minutes at a depth of 6,800 meters and immediately started to move upstream.

It feels much better if you go up a few hundred meters. Although you can feel the strong pressure of water pressure, the Overlord can stay at this depth for dozens of minutes, or even persist for more than an hour.

"Huh!"

Liu Yong had been paying attention to the situation of the cave wall, and finally saw something unusual, and couldn't help but say "Huh" in surprise.

"Battle, slow down, let me take a closer look at the cave wall."

Upon hearing this, the Overlord slowed down and even stopped eventually.
