Chen Yang, Yu Ziwen, Jiang Wentao, and Yan Guinan took the Longwu boat to the mountains 300 miles south of the futu river.

This mountain range looks very ordinary, and its geomantic omen is also very ordinary. Except for some ordinary people living on the edge of the mountain range, there is no one in the deep part of the mountain range.

Most people will never think that there is an ancient tomb hidden in this mountain range.

The four of Chen Yang flew down from the Longwu boat, flew low in the mountains and headed for the entrance of the ancient tomb.

In Ke Zeyao's hand drawn map, the geographical location is clearly marked.

But even so, it took them two hours to find the entrance.

The four stopped in front of a big tree with a diameter of seven or eight meters. The tree is more than 50 meters high and has luxuriant branches and leaves. I don't know how many years it has. The rings on it are so blurred that I can't see clearly.

At the bottom of the tree, there is a tree hole, about two meters wide and two meters high.

It's dark in the tree hole, and you can see the inner wall of the big tree.

According to Ke Zeyao's hand-painted map, this tree hole is the entrance to the ancient tomb.

Although the tree cave seems ordinary, as long as you go in, you can enter the ancient tomb.

At this time, a fat squirrel came out of the tree hole, looked at Chen Yang, and walked into the jungle.

Although it was fleeting, all four of Chen Yang sensed that the squirrel had a decadent smell. It was obvious that he had been in the closed underground space for a long time.

"Let's go."

As the leader of the team, Yan Guinan took the lead in walking into the tree hole.

Only his figure, gradually fade, and finally completely disappeared.

Jiang Wentao looks at Chen Yang and walks into the tree cave second.

Chen Yang and Yu Ziwen also went in.

After entering the tree cave, the scene immediately changed. The four people were in the cave, on the edge of a cliff. In front of them was an abyss. Fifty meters away, on the opposite side was a huge palace. There was a plaque hanging above the entrance of the palace, but there was no word on it.

Yan Guinan looks into the abyss and shoots his finger into the abyss.

"Jiji..."

The true Qi was like poking a hornet's nest. Under the abyss, there were sharp sounds, very harsh.

Then, a bat like monster flew up from the abyss, with a number of at least 2000.

However, these bats are not powerful, they are only red clawed bats in the late jiedan period.

Chen Yang four hands in succession, and soon cleaned up these red clawed bats, leaving a small part of them to flee and return to the abyss.

"The first hurdle is too simple."

Jiang Wentao puts away Yuanyang sword and looks at Chen Yang. It seems that he is mocking. The obstacles set by Chen Yang's ancestors are too low-end.

Yan Guinan looked at Jiang Wentao and said in a deep voice: "red clawed bat often appears with red clawed bat king. Don't take it lightly."

Jiang Wentao disagreed and said, "the red clawed bat king is just a four fold monster. It can't threaten us at all. Why care?"

Yan Guinan's eyes flashed a look of displeasure, but he patiently explained: "every ten red clawed bats, there may be a red clawed bat king to lead. That is to say, maybe hundreds of red clawed bat kings will appear from the abyss. "

Hearing this, Jiang Wentao changed his color slightly.

Although hundreds of red clawed bat king, not to kill them, but also can cause a lot of trouble.

What's more, if a person is dragged down the abyss carelessly, it's dark under him. I don't know what kind of crisis lurks.

Suddenly, the sound of flapping wings came from the abyss, like a tornado, whistling.

Then, more than 200 giant red clawed bat kings flew up from the abyss.

These red clawed bat kings didn't make any sound, but their fierce and evil spirit shrouded the abyss and scared people.

More than 200 red clawed bat kings attack at the same time. That momentum is quite terrible.

Jiang Wentao, Ke Zeyao and Yu Ziwen immediately attack the red clawed bat king.

They are so high that they often kill one with one sword.

But they found that Chen Yang stood in the same place, did not start, but from Najie, took out a strange machine that did not know what the origin, and stirred there.

"Chen Yang, why don't you do it?"

Jiang Wentao looks sulky and roars at Chen Yang.

As soon as his voice fell, suddenly, the fierce red clawed bat King seemed to be crazy. He no longer attacked Yu Ziwen and others. He just flew around and bumped into each other. ,

they are very fast, and often they will be seriously injured when they collide.

For a moment, blood splashed in the air, and the continuous impact made the red clawed bat King die and hurt more than half.

The rest of the red clawed bat kings, like headless flies, stumbled down the abyss.Seeing the last red clawed bat king, he bumped into the cliff of the abyss and then fell into the abyss. Yu Ziwen, Jiang Wentao and Yan Guinan could not help but gasp at the corners of their mouths. They did not know what had happened.

When the scene completely calmed down, Yan Guinan pondered: "these red clawed bat kings seem to have been disturbed and lost control of their flight direction."

Looking at Chen Yang, he turned his eyes and fell on the machine beside him. Thinking deeply, he asked, "younger martial brother Chen, did you do it?"

Chen Yang nodded and said with a smile, "elder martial brother Yan, smart."

Smell speech, Yan Guinan, Yu Ziwen, Jiang Wentao's eyes, all show the color of accident.

Chen Yang didn't even move, so he managed to get more than 200 red clawed bat kings. It's incredible.

Yu Ziwen came forward and asked, "Chen Yang, how did you do it?"

"Red clawed bat king, although he is a monster, he is still a kind of bat. Bats fly by the reflection of sound waves to judge the direction, distance and position. "

Chen Yang pointed to the machine beside him, and then said, "this is an ultrasonic emitter. Just now, after I turned it on, the ultrasonic wave disturbed the sound wave of red claw bat king. They received the wrong reflected sound wave, so they got out of control."

This explanation is very confusing to Yu Ziwen, who has never studied biology or physics.

Jiang Wentao came back and said in a cold voice, "Chen Yang, don't brag. We've never heard of ultrasound or reflection. What's your theory?"

Yan Guinan looked puzzled and asked, "younger martial brother Chen, where did you get this ultrasonic transmitter? I'm sorry I haven't heard of it before."

Chen Yang said: "I brought the ultrasonic transmitter from Diwu star. At that time, I just casually moved some instruments and put them in the Najie. Unexpectedly, they are used today. "

Hearing this, Yan Guinan raised his eyebrows and said, "diwuxing, it's said that the technology there is very advanced, but the cultivation is very backward. Younger martial brother Chen, are you from Diwu star? "
