Tianyu walked in front of the cave and Feng Wu walked behind. The darker the more he walked inside the cave, the better. Fortunately, both of them prepared torches, and the cave was full of oxygen. The two of them lit the torches and saw the road inside clearly.

As the two continued walking, they encountered a wall.

The wall looked like it was made of soil, completely sealing the hole that continued to move forward. Tianyu sprayed water directly onto the wall, but the wall did not move at all.

Feng Wu said: "It seems like a real wall, not a spell."

Tianyu wondered: "As it turns out, the other party closed the road intersection again and again, and the earthen wall seemed to be built from the outside, so it seemed that he didn't want people to enter."

Tianyu punched the earth wall, and the surrounding land fell one after another, and even the dust in front of his eyes was covered with dust.

After the dust settled, Feng Wu shouted from behind: "Are you okay? The wall is opened?"

Tianyu fell into his fist. Feng Wu saw that his fist was actually injured.

Tianyu asked Feng Wu to come over, but Feng Wu saw that the earthen wall was just a cover-up. The real door was behind the earthen wall. This door was made of diamond and could not be opened with even personal strength!

Feng Wu chopped at the door a few times, and suddenly the sword posed a spark on the door, but it was impossible to open the door.

Tianyu touched the door with his hand and said, "This door is more than three feet thick. I'm afraid it's a door that is blocked by several people with high internal strength. There is no such a strong master among this thief, and it is also done by people from the Star Emperor Palace."

Feng Wu sighed, "Then we can only go back. There is not even a lock hole in this door. Obviously, I don't want others to come in, and I even want to seal it forever!"

Tianyu also nodded and said, "It's a pity that I can only stop here, it's a pity, cough!"

When Tianyu sighed, he had no choice but to smash the wall with his right hand, and then he felt something in the wall being knocked down!

When Tianyu came back to his senses, he had already found a small door open behind him!

Feng Wu quickly went over and found that it was a back door, and few people passed by. Then he looked at the wall he had just knocked on it. It turned out that there was a red brick on it. The brick was a mechanism. After pressing it, the small door would automatically open!

Feng Wu immediately said, "This is really a way out!"

Tianyu looked at the ground and said, "There is no step in this place. There are few people coming in normally. I'm afraid that only the masters in the thief Li can know this!"

Then Tianyu continued to walk down, and he saw a staircase on the first floor. When he reached the end of the staircase, he found a sign.

The sign is written in red font: "The underground river ahead, be careful of the piranha!"

Feng Wu also saw the sign and said, "It seems that there is danger. No wonder there are so few people leaving."

However, although he said this, there is no other way except looking back. There is no way to continue moving forward as long as possible.

Not long after the two left, they saw a dark river, but the water was indeed green below the river. The water was once colored and the bottom of the river could not be seen clearly.

There are three rivers in total, and I don’t know where they flow. I saw a pool in the middle of this underground space. The water of the three rivers will eventually flow to the pool. There is another door opposite the pool. I am afraid that once that door opens, it will be the thief’s nest!

Feng Wu said, "This is an emergency passage."

Tianyu replied: "We walk on land, stay away from the water, so don't go in."

Feng Wu followed Tianyu's words and walked tightly against the wall. She felt that the river was quiet along the way, and there was not a single fish inside, let alone a piranha.

But just as the two of them walked to the pool water, they saw bubbles starting to pop up inside the water!

Tianyu immediately pushed Feng Wu behind him, and the bubbles that emerged automatically flew towards Tianyu.

The bubble contained green water. At first, I thought it was tightly floating around, but I found that the bubbles were moving regularly, and the direction was around Tianyu and Fengwu and his personal side!

Tianyu felt something was wrong, so he immediately picked up the stone and threw it at one of the bubbles. As a result, the bubbles instantly shattered and the green water inside also flowed out!

The green water immediately boiled after falling on the ground. Tianyu saw it and immediately said, "This thing has a corrosive effect, don't touch the body!"

Then Feng Wu also picked up the stones on the ground and threw them into the bubbles. With the combined efforts of the two, they could be considered to have broken all the bubbles.

But when the two of them were about to leave, they found that bubbles were still experiencing in the pond water, and the number of bubbles was twice as many as before. This time, the bubbles were blocked on the road ahead of the two. If they rushed over, the bubbles would inevitably be broken and corroded by the green water inside!

Tianyu stretched out his palm, facing the bubbles, a chapter came to beat the cow from the air!

Hearing something in the pool of water, he immediately sank, and Feng Wu also used his sword energy to cut off the bubble blocking the road ahead.

At this time, Feng Wu took a break, looked at the pool water, and found that in the center of the pool water, there were two eyes staring at him with fists!

Feng Wu shouted, "What is that!"

Tianyu also looked at that direction and found that a three-meter-long fish leaked its head. The fish was not much different from an ordinary carp, but the difference was that the whole body was green and bubbles were spitting in his mouth.

Tianyu immediately hit the fish's head with a stone, and the big fish instantly sank into the bottom of the pond.

Feng Wu said, "This is a piranha, it's too different from what I think!"

Tianyu pulled Feng Wu and rushed forward immediately. As a result, the big fish took a faster step, and emerged from the other direction. It could spew a green column of water to the two people!

In order to prevent being touched by the green water, the two people who were about to rush out were blocked back, and the big fish also changed the direction of the water column and sprayed towards the direction of the two people's retreat!

Tianyu said while evading: "The other party cannot get ashore, and it is not easy for us to go into the water. Think of a solution!"

Feng Wu lowered her head and pondered for a moment, then said, "I'll give it a try!"

Then Feng Wu pulled out the sword and put it into the water!

At first, the green water immediately boiled, but after a while, Feng Wu found that the Fengxiang sword was indeed extraordinary and could not be melted by the green water, so she happily said: "I can kill the big fish!"

Tianyu asked, "What are you going to do?"

Feng Wu stroked the sword and said, "Liuli, it's up to you, you have to be more powerful!"
Chapter completed!
