This time, you use such weapons because they are not easy to find. If you want weapons like guided bombs, I'm afraid they will be found by the immortal who has just taken them out.

With Li Zhi, Zhang Kui and Yuan Hong secretly come to Rouran's camp and begin to install these infrasound generators.

After the arrangement was finished, Li Zhi asked Zhang Kui and Yuan Hong to bring special sound insulation equipment. Yuan Hong was the first one who didn't believe it. He felt that his Majesty was too careful. Wasn't it just a small voice? What skills do you have? It's a big deal. He just covers his ears, doesn't he?

However, after listening for a while, Yuan Hong felt dizzy in his mind, and his internal organs vibrated. He looked at Li Zhi in horror. Li Zhi laughed and knew that Yuan Hong was not hurt much. At this time, Yuan Hong was also afraid. He quickly took the sound insulation equipment with him, and then said, "Your Majesty, these weapons are so powerful!"

At this time, in the army of Rouran nationality, all the people, soldiers and soldiers were forced to endure discomfort, and even some weak people had fallen to the ground and twitched for a long time.

Dukra is anxious, he has no control over the reaction now.

Just then, the wind was so strong that people couldn't open their eyes. After the wind fell to the ground, a Taoist wearing a black robe appeared. He was very ugly, with a sharp mouth and a long slap. It was terrifying to look at him.

And a pair of small round eyes, eyes with a shadow, but to see this person, Ducla is very happy.

He quickly stepped forward and said to the black robed Taoist in front of him: "I hope the immortal can help me! Now there is such a situation in Yingpan! We are not rivals

The black robed Taoist frowned and felt the sound around him. He frowned slightly. Then he rose up and disappeared into the night sky.

Dukra thought that this man had escaped, and he was very disappointed. At this time, there was a cry of birds in the sky, and then a huge crow appeared in the sky. The crow was dark, but it was too big compared with ordinary crows, right?

Two wings spread out, more than 20 feet!

The huge figure blocked out the sky and fanned the wings to support the scraping of the tents around, but it also had a certain effect, and even knocked down the sound equipment.

Li Zhiyi frowns, damn it! Did he destroy the infrasonic transmission equipment that he made?

You know, Li Zhi didn't bring a lot of these devices, but he didn't make a lot of them, because these frequencies are all in the experimental stage. I didn't expect that this time they were used on the battlefield, they were surprisingly good!

Li Zhi is going back to mass production!

Li Zhi is very gloomy, but now he can't care about what's in front of him, because there is a crisis in front of him, and a gust of wind comes not far ahead.

Unexpectedly found Li Zhi and Yuan Hong and others hiding place.

Li Zhi, Yuan Hong and others were caught off guard. They blew them into the air and fell to the ground.

However, he didn't hurt himself. At the same time, Li Zhi didn't know who the other party was coming from. He was so fierce!

But he secretly told Zhang Kui to let him rush to the military ambush, let them not act rashly, there are changes here!

Zhang Kui's figure disappeared in a flash when he received the order. He went back to send orders by means of the skill of local practice.
