When ye Pengfei thought of it, he suddenly felt a tumbling in the water. He quickly turned his head and looked at it, which made him jump.

In the river not far in front of him, a huge shadow was swimming towards him quickly. It was obviously coming towards him. The water was rolling and the movement was quite big.

Because the light in the water is too dark, ye Pengfei can't see what kind of creature he is, but judging from his huge body, he can guess that this creature has extraordinary strength after all.

What makes Ye Pengfei even more surprised is that since life in the underground river is so huge, he didn't notice it in advance, even the breath of the other party. You know, if it's a monster, there must be a breath on it. It can't be covered up at all, let alone such a huge thing.

But ye Pengfei really didn't feel the biological breath, which is very strange.

Ye Pengfei didn't think much about it. He said: "go!"

Shinan and Baili double swords become their own swords. Even if ye Pengfei doesn't have to be urged by Zhenyuan, the double swords can resist the enemy by themselves. After getting the instructions from ye Pengfei, Shuangjian immediately turns into two cold awns, facing the huge shadow.

The speed of the double swords is extremely fast. There is no doubt that they penetrate the body of the shadow. What makes Ye Pengfei even more surprised is that the shadow does not stop and still swims towards himself. Even after being penetrated by the double swords, he does not even howl.

Ye Pengfei was shocked. He didn't know what kind of creature had such strong vitality. After being pierced by the double swords, he didn't seem to be hurt at all.

Although shocked, his action didn't stop. While communicating with his double swords, he pushed his feet on the rocks in the water and rushed to the water.

When the shadow was about to rush in front of Ye Pengfei, he burst out of the water, hit the top of the cave directly, and instantly knocked a big hole out of the rock at the top of the cave.

At the foot of the water, the sound of "Hua la la" makes a big noise, and avoids the attack of the shadow. Ye Pengfei quickly looks down and sees the shadow in the water fluttering by, and then suddenly disappears in the water, as if he is invisible in the water.

Although the water surface of this underground river is spacious, it is not deep. It's only about five or six meters deep. Ye Pengfei can't imagine how this huge monster suddenly disappeared under his own eyes. Moreover, the water of this underground river is so shallow that he can find it even if he hides it.

But the other party just disappeared out of thin air under his eyes, without any omen.

Ye Pengfei is feeling strange when he suddenly sees the huge shadow that just disappeared. In a twinkling of an eye, it suddenly appears not far away. This time, with the light of the double swords, ye Pengfei finally sees clearly. The monster's body is more than ten meters wide and flat. It's like a giant bat fish, lying under the water, waiting to send a message to his opponent at any time A blow to life.

Ye Pengfei's body is half hanging on the cave, and once again surpasses the double swords to attack the monster in the water.

Since the last casting and tempering by tietouwa, Shinan and Baili double swords have become sharper. There are almost no things that can't be cut in or killed.

However, the two swords cut back and forth several times in succession, and the huge monster in the water did not move. It was as if it could not be killed. It was still dormant in the water as before.

"What the hell is this? It's so evil!" Ye Pengfei couldn't help cursing secretly. He couldn't figure out the details of the monster. Now he didn't dare to go into the water.

There are unknown powerful monsters in the water, and five white robed envoys on the ground. It's not too much to describe their current situation as heaven has no way to go to the earth.

"Poop, poop, poop!"

At this time, ye Pengfei suddenly heard that he had just dug through the ground and entered the underground river. There were three sounds of entering the water.

In his heart, he quickly turned around and saw three figures falling into the water from the mouth of the cave.

These three figures are exactly three of the nine people who went down to look for the trace of Ye Pengfei.

At this time, the huge shadow, which had been dormant, finally moved. With the sound of the water, the huge shadow rushed towards the three people.

When the shadow passed under the foot of Ye Pengfei, the light from the double swords came out. This time, ye Pengfei finally saw the shadow clearly.

This look, ye Pengfei involuntarily took a breath of cold air, cold sweat straight out on his back, very happy.

It turned out that the shadow was made up of innumerable small scales, which were about the size of a fingernail. Innumerable scales kept churning in the water, and the sound of the water just now came from these scales.

In fact, these small scales are not the scales of this huge monster, but a small fish only the size of a little finger. The small fish has a layer of scales on its back, which makes them look very similar to scales.

No wonder his double swords cut the monster's body in succession, but the monster still didn't fall down, let alone howl.So, what kind of behemoth is there?

Obviously, it is a huge school of fish formed by countless small fish in the water. The dense small fish gathered together, like a black cloud flying over the water, and like a huge water monster, attacking all creatures falling into the underground river.

The school of fish soon approached the three people who fell into the water. Then, ye Pengfei heard the three people scream bitterly. The three people kept attacking and killing the small fish. However, the small fish were covered with scales, which were so easy to kill. Even if one or two of them were killed, there would be more small fish surrounding and eating their flesh.

Soon, countless small fish rolling, the three completely submerged, their scream also quickly stopped.

Ye Pengfei looked at the scene not far away, and felt that his back was chilly. This kind of small fish was just like the piranhas in the world. As long as there were creatures falling into the waters under their control, they would rush on. No matter how strong your strength is, you can't kill them all in a short time. In just a few seconds, they can gnaw each other to the skeleton .

"In this underground river, there is still danger!"

If it is normal, ye Pengfei is not afraid of these piranhas. Can these piranhas be as powerful as his own sword?

But he can't use Zhenyuan now, and he can't sacrifice the supreme sword secret to kill them all. In this way, if he wants to go to Zhongzhou along the underground river, he will be in great danger. God knows if there will be similar piranhas in the future?

"Boom!"

At this moment, the ground trembled like an earthquake.
