After getting the information about Yan Jucheng, Luo Er immediately conveyed this information to the small bowl in the Xia family's military camp. The training of the Wooden Armor Soldiers and the Xia Jiajun was adjusted in a timely manner to better suit the offensive strategy.

That evening, the anti-brainwashing device made by Xiao Wuhua finally came out.

He and Han put several large boxes on the tablet, escorted by the wooden armor soldiers, and carefully transported them to the villages of Yanju City.

Han and I sat side by side, crouching on the edge of the large precious box.

These unsightly boxes are the key to our rescue of the people of Yanju City.

"It's not difficult to make devices, but the most difficult thing is to calculate the frequency." Xiao Wuhua touched the big box and explained to me, "Do you remember the device you wore last time you entered the palace?" That anti-brainwashing device is specifically aimed at you and is only useful if you wear it. But if you want to eliminate the frequency of several people, you need to use a superposition algorithm, and you need an instrument with several times the power. ”

"Hmm." Although I didn't understand, I still nodded, "In this way, the reason why Luo Qiuming and Han were not brainwashed is because their water prison is full of stones?" ”

Xiao Wuhua: "Yes, the signal penetration is not strong. That is, because most of the buildings in Yanju City are wooden structures, if you use stone to build houses, you can do a lot less. ”

Me: "No wonder you used stone when you built the Valley of the Warriors." ”

Xiao Wuhua seemed to think of something bad: "The stone house is also solid, and it is not easy to collapse in an earthquake, unlike wood that can be blown up at once." But there is also a problem with stones, if they are not firmly glued, the bricks can fall and kill people. ”

We approached the south gate of Yanju City, but instead of going directly to the gate, we went around to a city wall.

This is a private house.

"Is there anyone in there?" Xiao Wuhua picked up a stone on the ground and threw it into the city wall.

"Smack."

Stones hit the roof and rolled down.

"Whew......" "Hahahaha!"

Soon, there was a strange movement on the other side of the wall, as if a lot of wild beasts had suddenly appeared and crowded on the other side of the wall.

Xiao Wuhua raised her hand: "It's okay, turn on the power!" ”

Han stood on the edge of the machine and raised his hand to press a switch.

"Buzz—"

A scalp-tinging beep rippled from the machine, and the vibration felt like a mind attack.

I and the surrounding wooden armor soldiers unconsciously retreated, and some of them were nauseous and retching at that time, and were dragged away by my hands when I retreated. Xiao Wuhua and Han covered their ears almost at the same time and slipped back, Han took a few steps back and ran away quickly, quickly leaving the others far behind.

I shouted, "Ah! You bastard won't take me away! ”

Han: "I didn't break my leg, I ran by myself!" ”

I covered my ears: "Mom, this is really hurting the enemy by a thousand and self-inflicting eight hundred!" ”

Wooden Armor: "......"

We retreated a few feet away, and the vibration decreased. Sure enough, what Xiao Wuhua said was true, this machine can cover the houses on both sides of the street. As long as the machine is effective, push the machine forward, and the bewitched inhabitants will be able to regain their senses.

Xiao Wuhua: "I developed it independently!" That's a good thing! ”

Me: "Didn't people do it themselves?" ”

"She's really not ......" Han pointed to the back of Xiao Wuhua's hand, "The nerves connected to his pretend hands and Wangqiu's pretend brain are different. ”

Xiao Wuhua: "That's it!" ”

"That's really embarrassing Senior Brother Xiao!" I patted him on the shoulder, reluctantly complimented, and asked, "But we can't get close to the wall now, so how can we be sure that it works?" ”
