Gan Ning gestured around the fence, and after determining the size of the fence he was going to break, he quickly set to action.

This time, he didn't retain any strength, and took out the Split Sea Broken Wave Halberd and slammed it into the steel bar of the fence, and every time he poured, he could poke off a large part of the steel bar, but compared to the thick steel bar there, it was relatively slow. He is now a little envious of those generals who use sword weapons, if Huang Zhong is to deal with this fence, it is estimated that two or three knives can cut a steel bar, how can he poke it slowly here? However, he also knew that it was impossible for Huang Zhong to dive to such a depth, not that Huang Zhong's strength was not enough, but that his water nature was too far worse than Gan Ning. At this depth, I'm afraid he has been suffocated to death in one breath before he has been crushed to death.

It took about a minute or two for Gan Ning to break one steel bar, and then continued to work on the second one......

Ten minutes later, Gan Ning finally made a hole in the fence that was enough for him to pass through, and by this time the breath in his stomach was about to run out. Therefore, he did not delay, and got through it at one end, and then quickly floated up along the steel bar that he was holding on to when he dived down.

The speed of coming up was indeed much faster than the speed of diving, and in less than a minute, Gan Ning had already appeared on the surface of the sea.

Through the fence, Gan Ning could clearly see the small reed poles floating on the opposite side, and he knew that under the reed poles were the fifty Jinfan sailors he had brought. The reason why he hides underwater is naturally because he is worried that he will be discovered by the other party, although this probability is very small, but it is always right to be careful.

He didn't greet these sailors, and after making a mark on the steel bar he was holding, Gan Ning continued to march along the arch.

After a moment, a trace of shock rose in Gan Ning's heart. Originally, according to his idea, this level was like a city wall. That shouldn't be too thick, even if the main god makes this thing a little perverted, it can reach the sky for one or two hundred meters, right? The walls of one or two hundred meters thick are definitely scare some people. With such a thickness, even if it is made of ordinary boulders, it is not a boulder thrown by a catapult that can collapse, even if it is a siege vehicle specially used to siege the city, it will only be defeated when encountering such a thick wall. Because this is no longer a city wall, it is just a city directly......

But now. Gan Ning found that his idea was too simple. He had walked about two hundred meters from the fence, but he still walked through the arch, and could not see the end of the arch as far as he could see. You know, though, it's pitch black in here. But with his strength, he can still see a blurry image nearly 100 meters away. That is, the depth of this arch will not be less than three hundred meters at least!

This is not the most perverted, Yang Tian also found that inside this arch, there are shooting holes every thirty or forty meters, and the positions of these shooting holes are high and low, and the high ones are almost forty or fifty meters away from the water surface. The low one is only two or three meters.

Some people may think that there is only one shooting hole so far away, how much of an attack effect can be produced? But it must be mentioned that this shooting hole is much larger than the ordinary bow and arrow shooting hole, if Gan Ning is not mistaken. Then this shooting hole is definitely reserved for the ballista. It is conceivable that after the enemy ships entered this arch, these firing holes would be absolutely nightmarish.

It's just that most of these shooting holes are currently unguarded, and it is completely pitch black inside. But every ten firing holes, one is lit with a torch. It was clear that there was someone on duty inside. And when encountering this kind of manned shooting hole, Gan Ning had no choice but to dive into the water to dodge.

And this infiltration, Yang Tian found a more strict thing, almost sixty or seventy meters away from the water surface, there is actually a huge mace-like thing lying horizontally, if there is any difference between this mace and ordinary mace, it is that the iron nails on it are too long and too thick.

From where the mace was placed on both sides, Gan Ning found that the thing could be raised and lowered. From this, he also guessed the purpose of this thing, that is, when an enemy ship entered the arch, it could raise these mace-like things, and if those ships collided with them at a very fast speed, they would inevitably end up with a shipwreck.

Thinking of this, although Gan Ning was in the icy seawater, he couldn't help but break out in a cold sweat on his forehead. You must know that when he first saw the fence, he thought of the easiest way to pass through the national level, that is, let him and Huang Zhong and others be the vanguard, quickly enter the arch to destroy the fence, and then rush through it at the speed of the Sea King giant ship, which can also avoid direct contact with the defenders on the level.

But now that he saw the setting in the arch, he realized how crazy his idea was. This level is too perverted!

Collecting his feelings, Gan Ning continued to swim forward, and soon, he stopped, because he found that two passages had appeared in front of him, and the width of these two passages was no narrower than the passage he had entered.

Gan Ning was a little embarrassed at this time, he swam over from the fence, at least a distance of nearly a kilometer, at this time he was already numb to the thickness of this level, so he didn't care very much. But now there are two passages, and he has no way of knowing where they lead, how can he choose?

In the end, Gan Ning still didn't intend to give up like this, and in the absence of other ways, he had to use the stupidest method. Since we don't know where these two passages lead, we can explore them one by one. He is also a master of art and bold, and he is not afraid of whether there will be any traps waiting for him in front of him.

Gan Ning decided to take the right passage first, and after he had traveled about two or three kilometers, he noticed that there was a fork in the road ahead. However, the fork in the road was slightly different from the one just now, and both directions of the fork were directly in front of the direction of their progress. But now one of the two roads at this fork in the road is instead going in the direction from which it came. And the angle between this arch and the other fork in the guò is about the same as the angle of the fork formed by the first fork.

Gan Ning, who couldn't figure out the situation, had to continue to choose to move to the right, which had the advantage of not getting lost when he encountered many forks in the road.

But this time God didn't joke with him again, and after advancing a kilometer of distance, Gan Ning found a fence again, exactly the same as the one he had entered before. Outside this fence, the same microwave rippling sea surface is similar to the Dahan Sea. And as far as his line of sight could not see any ships, and he had no way of knowing what the boundaries were ahead. (To be continued)
