A classmate looked at the oversized bag of walkie-talkies and let out a sigh.

"Hmph, I've walked a long way with this bag of walkie-talkies on my back, and my back hurts."

Chen Changyong complained a little.

Classmates (on the surface): "Oh, teacher, you've worked so hard. ”

But inwardly: why didn't you tire you to death? We'll not have to do our chemistry homework if we're tired of you, hahaha!!

"One group to get the walkie-talkie."

Yan Bai and others lined up to get the walkie-talkie.

"Three groups coming."

"Five groups."

Chen Changyong first distributed the walkie-talkie to the classmates who were going to the mountain.

"For the even-numbered group, send three representatives out to get the walkie-talkie."

"Two groups."

"Four groups."

"Come, the rest of the group, send two people to get the walkie-talkie."

"Teacher, why do we have the least walkie-talkies?"

The groups scouring the countryside for ingredients were a little unbalanced.

There are only two walkie-talkies in their group, which is simply a difference!

"Listen to me, the students who go to the mountain still have to walk the mountain road, the mountain is dark and black, in case you get lost, it will be troublesome, and this mountain is so big, how can you not have a walkie-talkie?"

"The students who go to the rice fields, although it is not as difficult as in the mountains, but their range of activities is larger than yours, and you think they are easy, they also have to do farm work, helping the farmer uncle to threh grain.

And you need to find the ingredients in the rice fields by yourself. ”

"You are actually the most comfortable to walk in the village, and your range of activities is relatively small, so it is enough to divide into two groups."

"You want to communicate with the villagers or something halfway, is it possible to communicate individually?"

Chen Changyong explained a bunch.

The rest of the groups thought about it, and it seemed that it was really reasonable.

As a result, several of them were successfully fooled by Chen Changyong.

"Have you got the walkie-talkie?"

"Got it."

"You guys use it first and see if you can use it."

Chen Changyong said: "I remember that every student with a walkie-talkie should make their walkie-talkie on the public channel, and your group wants to communicate, you can build a group channel." ”

"Good, good."

After Chen Changyong's words fell, the students began to tinker with the walkie-talkie.

For a time, the whole venue was.

"Hey? Can you hear me? ”

"Oh, I can hear you."

Mu Qi adjusted the walkie-talkie of the whole group in two or three clicks.

"In vain, give me your walkie-talkie, and I'll tune it for you."

Mu Qi walked to Yan Bai's side.

"Okay."

Yan Bai handed him the walkie-talkie, and she didn't know how to get this thing.

Mu Qi's fingertips worked on the button of the walkie-talkie, and after a while, Yan Bai was added to the public channel, and at the same time, he also set up a group channel for them.

Yan Bai saw Mu Qi's bells and whistles, so he got the walkie-talkie ready.

"Give."

Mu Qi returned the walkie-talkie to her.

Yan Bai took it and looked at it, there was one more channel on her walkie-talkie.

That's a private channel.

"This ......"

Yan Bai pointed to the private channel.

"This channel is linked to my walkie-talkie, you can enter this channel and talk to me."

Mu Qi explained.

Yan Bai: "Huh? "Yes.

After reacting, the little face was slightly red.

"The two of us are not in the same group, the mountain road is not easy to walk, you have to be careful."

"Got it."

Yan Bai took the walkie-talkie and nodded.

"Remember to talk to me privately."
