In the era of human life, in the area where human beings lived, solar panels were erected on the roof and roof.

Only in a wide field will a large number of solar panels be erected on the ground.

However, in the tribe where Bai Guoguo lived at this time, it was obviously impossible to fix solar panels on the roof.

Therefore, this piece of vacant land that has been cleaned up is the power generation paradise of Baiguoguo.

After placing the solar panels one by one, fixing the base with stones and wood, Bai Guoguo hurriedly connected the wires and storage batteries.

It was just over one o'clock in the afternoon, and it was the time for the ginkgo fruit hand to be displayed.

The sun was already slanting a little westward, but it was a sunny day.

Seeing the prompt light on the battery, Bai Guoguo almost cried out with excitement.

"It's done! It's done! ”

Bai Guoguo screamed, grabbed his heavy winged hands, and kept bouncing on the ground.

Seeing Bai Guoguo so excited, Chongyi was puzzled and amused, but she still pulled herself to jump and shout.

The burst of laughter drew the rest of the tribe.

As soon as everyone heard the voice of Bai Guoguo, they hurriedly put down their work and rushed over.

When he saw the rows of unknown objects on the ground, some people wondered.

"Miss Guoguo, what are these things? Is it a trap you've newly studied? ”

When Bai Guoguo heard this, he laughed and said, "No! But if this thing is used well, it will work much better than the traps we use now! ”

People are very fond of traps right now.

If it weren't for the traps, it is estimated that when the wolves attacked, at least half of the people in the tribe would have been killed or injured.

But now, except for a few people who have been injured and are now in the recovery period, everyone else is fine.

When I heard that this was something more powerful than a trap, everyone's eyes were shining.

The woman who walks around more with Bai Guoguo on weekdays greeted with a smile: "Guoguo, you can show it to everyone!" ”

"Yes, Guoguo, let everyone see how these things are used!"

The crowd echoed.

Bai Guoguo looked at the charging amount prompted by the battery, and finally gave up the idea of showing everyone.

"What is shown, let's go back and talk about it, now this thing is not enough energy, it's better not to move."

After speaking, Bai Guoguo realized that these people probably didn't understand the meaning of "lack of energy", so he changed his explanation to explain it.

"It's like eating for us, eating is about providing energy. If we don't eat enough, then our body is not full of energy, and we can't work well. ”

Sure enough, after listening to this explanation, everyone suddenly realized.

"Guoguo, how does this thing provide energy? Do you use meat? Or is it wood? ”

Someone else asked another question, and once again focused everyone's attention.

Bai Guoguo smiled, pointed to the solar panels, and said, "Those things are the things that can provide energy to this baby." Don't touch these things on weekdays, and when you have enough energy here, I'll definitely give you a demonstration. ”

got the promise of Baiguoguo, and everyone was satisfied and dispersed.

Seeing that Bai Guoguo had recovered a little, and was no longer just bouncing, Chongyi asked, "Guoguo, how long does it take to provide enough energy?" Will it take a long time? ”
