The entrance to the triangle was very narrow, and the open oxygen cylinder was stuck in the hole, and it took a lot of effort to get into it. Pen, fun, and www.biquge.info

The cave is completely dark, and even if it is illuminated by glow sticks, the visibility is very limited.

Through the bubble-filled lake, Hu Kai could see that the stone slabs in the cave were covered with blue-black seaweed, and some fish and shrimp were hidden here, and after being disturbed, they quickly burrowed into the darkness. Hu Kai even worries that there will be powerful creatures such as sharks or crocodiles here?

The further you go, the more open the passage becomes, and gradually people can move freely without having to tighten their bodies. Although the passage did not turn, it gradually rose in height as you entered the passage.

Soon they found a stone staircase at their feet, and in less than five minutes they were leaping out of the water and back to land.

Whoa......

The water was churning, and the four of them jumped out of the water and looked up, but they saw that this was a small hall, surrounded by old boulders, and some blue-black mosses also grew on the boulders.

At the end of the stairs was a narrow platform, and four people climbed onto the platform and began to take off their wetsuits. Although it was only a short dive of about 20 minutes, the oppressive scene and the heavy burden made them breathless, and they were already sweating profusely.

After taking off their wetsuits, everyone felt more relaxed. In order to be able to shine brighter, Ivan took out two more glow sticks and lit them.

The hall in front of you is square, roughly similar to a sewer. The air is humid and the temperature is neither hot nor cold.

At first, Hu Kai was worried that if no one cared about it for hundreds of years, it would deposit too much carbon dioxide and affect his breathing. However, when he saw a few fat and large rats in the corner, he dispelled his fears.

The four of them did not dare to delay time, and after they put away their wetsuits and oxygen cylinders, they began to pick up their backpacks and head for the depths of the passage.

There was only a narrow passage directly in front of the hall, and the four of them had no other choice but to quickly enter it.

The passageway is surrounded by huge stone slabs, which shows how majestic and stocky the walls of the Imperial Island are. Everyone walked along this aisle for a long time, but found that the aisle was getting narrower and narrower, and the narrowest place could only be passed sideways.

However, the passage is a straight one, and it is estimated that it was originally used as an emergency escape route. Hu Kai and the four of them soon came to the end of the passage, but saw that there was a stone gate in front of them, as the wolf girl said.

The stone gate is one meter wide and two meters high, and there are many diamond-shaped holes in the center where you can directly see the situation outside the door.

"This is it!" Hu Kai touched the stone door, although it was old, it was still as strong as ever, and it didn't move at all.

"If you bring a sledgehammer, you shouldn't have to blast it open!" Lao De touched the stone gate while starting to prepare explosives.

"I don't know......," Miss Pearl asked, "how far is it from where the guards are?" After the explosion, we still haven't had time to escape? ”

"I can't say!" Hu Kai shook his head, "It's the third watch in the middle of the night, if you blow it up suddenly, it will inevitably be heard!" As for the explosion, it's up to our luck! ”

"In that case," Miss Pearl said, taking off her backpack, "let's change our clothes beforehand!" Save the time in a hurry! ”

"Yes!"

Hu opened the backpack and began to put on the clothes arranged for them by the wolf girl. After entering the royal city, it was naturally impossible for them to wear the clothes of saints, and what the wolf girl prepared for them was a kind of clergy clothing similar to that of saints, and the greatest advantage of this clothing was that it also had a veil to cover their faces.

After putting it on, Lao De, who was about to blast, was a little difficult. It turned out that this place was a straight road, and if the stone gate was blasted, they would not have any shelter. If you get too close, you will be blown up by stones; If it's too far, the fuse isn't that long!

Hu Kai pondered for a moment and decided to let his teammates stand in a safe place, and the fuse was ignited by himself. Because Hu Kai was wearing gold silk soft armor, if he was really hit by a stone, he would have more layers of insurance than others.

After explaining, the teammates did not argue with Hu Kai, and Lao De handed over the fuse to Hu Kai after installing the explosives.

It turned out to be smoother than they expected, and after the explosives exploded, the stones cracked in all directions, but they were far from threatening everyone.

It turned out that the wolf girl had adjusted the amount of the explosives package early in the morning, and there was no powerful explosion. Otherwise, with the opening explosives of Mica Mountain, it is strange that this small passage must not collapse!

However, Rao is like this, the vibration caused by the explosion just now is not small, and this time, the soldiers guarding the city wall will definitely not be able to sleep! It won't be long before they find it.

Without further ado, Hu Kai and the others hurriedly packed their luggage, quickly walked through the broken stone gate, and ran forward. Outside the stone gate, there is another straight passage, which is also very narrow.

Several people sped up, and soon came to a downward staircase, and there was a foul smell from the bottom of the stairs, which was obviously the sewer that the wolf girl had said.

Seeing the sewer, which meant that the exit was about to be reached, the four of them rushed down without hesitation. Sure enough, the sewer visceral water was cross-current, full of filth, and there were groups of large and small rats, which were countless.

The sewers extend in all directions, and Hu Kai casually found a direction to run. As the crowd searched for an exit, a distinct shouting could be heard overhead, and it seemed that the people above were attracted by the explosion.

The sewers of Imperial Island are similar to those seen in "Teenage Mutant Ninja Turtles", and they are even more spacious than that, and the four of them went around and around for a long time before finally seeing a manhole cover.

However, the depressing thing came, when Hu Kai climbed along the ladder to the bottom of the manhole cover, he found that the manhole cover was locked and could not be opened!

No way?

What is the situation?

Why is the manhole cover still locked?

Hu Kai pushed hard a few more times, but the manhole cover still didn't move. However, when pushing, Hu Kai thought of a possibility, isn't it, something is pressed on this manhole cover? Like what...... Car?

Right!

If that's the case, then it makes sense!

Thinking of this, Hu Kai had no choice but to return to the sewer with his teammates and continue to look for other exits. This time, they wandered around for nearly a quarter of an hour before finding another manhole cover.

However, the depressing thing came, and this manhole cover still couldn't be opened!
