Gan Ning gestured near this fence, and after determining the size he was about to break, he quickly began to act...

This time he did not retain any strength. He took out the sea-breaking wave halberd and stabbed it into the steel bars of the fence. Every time he could poke a large piece of the steel bars, but compared with the steel bars with the thick arm, this was relatively slow. He now envied those generals who used sword-like weapons. If Huang Zhong was asked to deal with this fence, he would probably cut off a steel bar in two or three swords. How could he poke slowly here? However, he also knew that Huang Zhong could not dive to such a depth. It was not that Huang Zhong's strength was not enough, but that his Shui surname was too far inferior to Gan Ning. At this depth, he was probably suffocated to death before he was crushed to death.

After almost one or two minutes, Gan Ning broke a steel bar and continued to work the second one... Ten minutes later, Gan Ning finally made a hole in the fence that was enough for him to pass through, and the breath in his belly was almost exhausted. Therefore, he did not delay and drilled over and then quickly floated up along the steel bar he was holding when he was diving down.

The speed of coming up is indeed much faster than the speed of diving. In less than a minute, Gan Ning appeared on the sea.

Through the fence, Gan Ning could clearly see the small reed poles floating opposite. He knew that under these reed poles, the fifty sailing naval troops he brought. The reason why he hid under the water was naturally worried that he would be discovered by the other party. Although the probability of this is very small, it is always right to be careful.

He did not call on these Jinfan navy troops. After marking the steel bar he was holding, Gan Ning continued to move forward along the arch.

After a moment, Gan Ning felt a little shocked. According to his idea, since this level is like a city wall, it should not be very thick. Even if the main god makes this thing a little abnormal, it can reach the sky with one or two hundred meters? A city wall of one or two hundred meters thick will definitely scare some people. With such a thickness, even if it is made of ordinary giant stones, it will not be able to collapse the huge rocks thrown by a stone caster. Even if it is a siege car specially used to siege cities, it will only be

The retreat was because this was no longer a city wall, it was just a city... But now, Gan Ning found that his idea was too simple. From the fence, he had walked about two hundred meters away, but he still walked through the arch, and within his field of vision, he could not see the end of the arch. You should know that although it was pitch black, with his strength, he could still see blurry images nearly a hundred meters away. In other words, the depth of this arch would not be lower than three hundred meters at least!

This is not the most abnormal. Yang Tian also found that there is a shooting hole every thirty or forty meters in this arch. The locations of these shooting holes are high and low. The height is about forty or fifty meters away from the water surface, while the lower one is only two or three meters.

Perhaps some people think that there is a shooting hole so far away, how big the attack effect can it produce? But one thing must be mentioned is that this shooting hole is much larger than an ordinary bow and arrow shooting hole. If Gan Ning is not wrong, then this shooting hole is definitely left for the crossbow cart. It can be imagined that after the enemy ship enters the arch, these shooting holes will definitely be a nightmare existence.

However, most of these shooting holes are not guarded at present, and they are completely pitch black inside. However, every ten shooting holes, one is lit with a torch, and it is obvious that someone is on duty inside. When encountering such shooting holes with people on duty, Gan Ning had to sneak into the water to avoid it.

However, Yang Tian discovered something even more serious when he penetrated. A huge mace was placed horizontally at about sixty or seventy meters away from the water surface. If there is any difference between this mace and an ordinary mace, it is that the iron nails on it are too long and too thick.

Gan Ning found that this thing could be lifted and lowered from the position where the mace was placed on both sides. From this he also guessed the function of this thing, that is, when an enemy ship entered the arch, these things similar to maces could be raised. If those ships crashed at an extremely fast speed, they would inevitably end up with a ship being destroyed and people being killed.

Thinking of this, although Gan Ning was in the cold sea water, he couldn't help but sweat on his forehead. You should know that when he first saw the fence, he thought of the easiest way to pass this national level, which was to let him and Huang Zhong and others be pioneers, quickly enter under the arch to destroy the fence, and then rush over with the speed of the Sea King's giant ship, which can avoid direct contact with the defenders on the level.

But now that he has seen the settings in this arch, he knows how crazy his thoughts were. This level is too perverted!

After calming down his emotions, Gan Ning continued to swim forward. Soon, he stopped because he found that there were two passages in front of him, and the width of these two passages was not narrower than the passage he came in.

Gan Ning was a little embarrassed at this time. He swam over from the fence for at least nearly one kilometer. At this time, he was already numb about the thickness of this level, so he didn't care much. But now two channels appeared, and he had no idea where these two channels led and how to choose?

In the end, Gan Ning didn't plan to give up just like this. Without any other way, he had to use the stupidest method. Since he didn't know where these two channels lead, he could investigate one by one. He was also very skilled and brave, and was not afraid of whether there would be any traps ahead waiting for him.

Gan Ning decided to take the right passage first. After he walked about two or three kilometers away, he found a fork in front of him. However, the fork just now was slightly different from the one just now. Both directions of the fork were in front of him. But now one of the two roads at this fork was in the direction he came from. The angle formed by the arch and the other fork he passed was about the same as the angle formed by the first fork.

Gan Ning, who couldn't figure out the situation, had to continue to move forward to the right. The advantage of this was that he would not get lost when he encountered many forks.

But this time God did not joke with him again. After moving a kilometer away, Gan Ning once again discovered a fence, a fence that was exactly the same as the one he had entered before. Outside this fence, the sea surface was also rippling, similar to the sea area of ​​the Han Dynasty. And within his sight, he did not see any ships, and he had no way of knowing what territory was ahead.
