Two people stop, Leng Leng looking at the sky suddenly appeared in a scene, the heart is full of horror.

Other birds seem to be aware of the danger, have scattered and fled, in the run, there are countless birds inexplicably burst.

For a time, countless pieces of meat kept falling to the ground, and soon covered the lake with a layer of broken bodies.

Soon, all the birds hovering over the lake have disappeared without a trace. Some of them have fled in horror, some of them have become a pile of broken meat. What looked beautiful at the beginning is terrible at the moment.

The drunken Madman's dim eyes lit up again in an instant. He took Xu Shaotang and said, "let's go and see what's going on! "

Xu Shaotang shakes his head, grabs the drunk maniac who is going to investigate, points to the broken meat on the surface of the lake and says," let's see first. Do you want to end up with those birds? "

now, he doesn't want to enjoy the beautiful scenery in the valley. Instead, he is inexplicably frightened. It has almost become a meat grinder, and he doesn't want to die here for no reason.

Although the alcoholic maniac is eager to know the cause of the death of the birds, but in Xu Shaotang's reminder, or temporarily give up the idea of the past investigation.

Half an hour later, there was no abnormal situation in the air. They looked at each other and began to move slowly towards the lake.

More than ten meters away from the lake, Xu Shaotang grabbed the drunk madman who was going on and shook his head to his forehead.

In the puzzled look of the drunk maniac, Xu Shaotang squats down, picks up a branch and throws it into the air. After rising for a certain distance, the branch quickly falls into the lake, and there is nothing different from the beginning to the end.

”You are too careful! "The drunk maniac laughs.

Xu Shaotang said: "it's really weird here. Be careful to make Wannian boat!"

After making sure there was nothing wrong with the branches, they approached the lake side by side carefully.

Less than five meters away from the lake, Xu Shaotang felt tight in his heart. Then he felt dizzy, his ears were buzzing, and his blood was rolling in his chest, as if he would explode at any time.

"Back up!" Xu Shaotang pulls the same dizzy alcoholic madman and retreats quickly.

After withdrawing for a certain distance, the feeling of dizziness gradually disappeared. They shook their heads hard to dispel the discomfort.

The alcoholic madman resisted the feeling of nausea and nausea, and asked Xu Shaotang with a dignified face: "do you know what's going on?"

Xu Shaotang rubbed his head, forced the feeling of blood rolling in his heart, and said: "infrasonic weapon!"

As far as he knows, the infrasonic weapons in the world are only at the research stage. Even if the results are occasionally displayed, they are not very powerful and can not form such lethality.

However, he was shocked that there was such a powerful infrasonic weapon in the forest. He believed that if they had been a few seconds late to get out of the infrasonic weapon's attack range, they would have come to the same end as those birds.

What made him even more difficult to understand was that when they entered the lake just now, they were not attacked by infrasonic weapons. Now where did the infrasonic weapons come from?

"Infrasonic weapon?" Drunk crazy hard swallow saliva, obviously also heard the power of infrasonic weapons, doubt: "how can there be infrasonic weapons here?"

"I don't know!" Xu Shaotang shakes his head. He also wants to know why there are infrasonic weapons here. Just when he is puzzled, he suddenly thinks of a possibility and asks the alcoholic maniac, "did you encounter anything in the process of searching for traces just now? "

before they went to the lake, they were all well, but after the drunk maniac went ashore, he was unwilling to look for a circle. He guessed that it might be something that the drunk maniac encountered in the process of searching, which led to the activation of the infrasonic weapon hidden in the valley.

Wine maniac carefully recalled the search process, suddenly patted his head: "I remember, just now I knocked on the cliff behind the dragon blood tree!"

They immediately followed the dragon blood tree that the drunk maniac pointed to. The drunk maniac pointed to the mossy cliff and said, "here it is!"

Xu Shaotang goes to the cliff, where there are traces of drunkard knocking. He quickly tears the moss off the cliff.

When the moss is cleared, the cliff shows its original appearance. There is a slightly raised stone where the drunkard knocks, and obvious traces of manual excavation can be seen beside the stone.

"It should be here!" Xu Shaotang gently stroked the slightly raised place on the cliff and gently pressed it down.

After pressing the switch on the cliff, Xu Shaotang tried to approach the lake slowly again. This time, the tumbling feeling of the five zang organs had disappeared.

Xu Shaotang stepped back a little and said to the drunk madman beside the cliff, "you can try again!"

The drunk madman pressed the button on the cliff again according to his words. Even though he had retreated a little, the extremely uncomfortable feeling came again. Xu Shaotang quickly got out of the attack range of infrasonic weapons.After retreating to the drunk maniac, Xu Shaotang pointed to the lake and said, "it seems that there is something strange in the lake. This time, the sonic weapon should be to protect the things in the lake."

"Why don't we go again?" After the alcoholic madman turned off the infrasonic weapon, he rubbed his hands and said excitedly.

Xu Shaotang was also somewhat moved and nodded: "let's look for the place where the sonic weapon was sent out first. Going to the lake is like looking for a needle in a haystack."

The drunk madman nodded and agreed. They set out cautiously towards the lake. This time, they were very careful, and they didn't let go of any flowers or grass on the ground.

Careful search, Xu Shaotang finally found a clue.

Four or five meters near the edge of the small lake, several small stones attracted Xu Shaotang's attention. When he gently knocked on the stone, there was no difference in the first few stones, but there was a "buzzing" sound from the oval stone.

After Xu Shaotang found the wet stone, the drunk madman also found the same stone on the other side.

After a search, they found eight strange stones on the edge of the lake, which tightly surrounded the whole lake. Once the button on the cliff was pressed, no one or equipment could enter the lake from any direction.

This discovery made them very excited. They immediately started to move the strange stones. However, no matter how hard they tried, the strange stones did not move
