Du He almost wanted to hit someone: "Don't be so naughty, hurry up and call Lao Sun, Miss Mo has a heat stroke."

"oh oh……"

Only then did everyone react and hurried to call for someone.

After sending Mo Yifei back to the room, Du He knew that this was not an easy matter, so he announced that everyone in the Dream Group would take half a day off before returning to the room.

"System, I want to draw a lottery!"

Du He looked at his shock value of more than 3000 and said generously.

From a month ago, he began to accumulate shock points subconsciously, and he planned to upgrade the system after collecting 50 shock points.

Unexpectedly, I can't help but want to draw a lottery every few days, and the shock value can't go up.

System: "Host, do you want to spend 100 shock points to draw a lottery!"

"Yes!"

Ding!

"Congratulations to the host, you got a solar electric fan."

puff.

A large box as tall as a person appeared in front of Du He out of thin air.

Du He took a closer look, and suddenly laughed wildly: "Solar electric fan? Doesn't it mean that it can be used when there is sun? Hahaha, the shitty system is finally willing to choose a decent thing."

Chapter 279 Little Beauty Big Popsicle

Du He hastily exited the system and couldn't wait to open the box.

A solar electric fan appeared in front of him.

This is a fan with a height of half a person. The base of the battery is under it. It is about a foot high. There is nothing special about the fan. The key is a solar charging panel that is as tall as a person at the back, but it is very scary.

Du He took a closer look, and immediately scolded: "Nimma, the dog system."

It turns out that the solar charging board is fixed on the base.

Du He scolded: "Could it be possible that this young master needs to go under the sun to fan the fan? No, this is too silly. We have to find a way to reform it."

As he spoke, Duhe took out the hammer from his toolbox, and after a while of bang bang bang bang, he finally separated the solar charging panel from the fan.

Afterwards, Du He rushed to the R&D center and asked Lao Yuan to find a few skilled craftsmen to start making copper wires.

After spending a whole afternoon, Du He guarded several craftsmen, and finally forged two copper wires about two feet long, and happily brought them back to his room.

Back in the room, he called Lu Bu, first put the solar charging board on the roof, then connected the copper wires under the solar charging board, led them around the pillars back into the room, and connected them to the electric fan.

Kata.

Turn on the switch, and the fan starts to spin.

Du He pulled over a rotating wooden chair, half-lyed up, and said contentedly: "Such a small day, even an emperor wouldn't change it, hahaha..."

Before the words fell, a voice sounded from outside: "Du He, do you want to rebel?"

Du He knew it was Li Lizhi without guessing.

He turned his head and saw Li Yuanshu and Li Lizhi walking in together.

Li Lizhi was like a little milk dog, with her mouth open, sticking out her little tongue to dissipate heat.

As soon as Li Yuanshu walked in, she asked curiously, "Why is it so cool in this room?"

The little beauty Li Lizhi also showed doubts, then stared at the fan behind Du He with wide eyes, and asked in surprise: "What is this? It can generate wind?"

The two beauties, big and small, immediately surrounded the electric fan and made a surprised sound.

……

Mo Yifei opened his eyes and found himself lying on the bed. The first thing he didn't care about was his illness, but hurriedly looked for the blueprint of the three-leaf fan that Du He gave him.

Then she found the blueprint beside her.

Regardless of the dizziness coming from his head, Mo Yifei actually picked up the blueprint and ran to the laboratory.

After staying in the laboratory until the second watch, Mo Yifei dragged his tired body back to the room, with a proud and proud smile on his face.

At dawn the next day, Mo Yifei took the craftsmen to the furniture factory production workshop, worked hard all morning, and finally installed a huge three-bladed fan.

In fact, it is not difficult to make a fan. The difficult thing is to drive the fan with water power. After some improvements by Mo Yifei, the fan started whirring in a short time.

The workers who were still on the assembly line of the furniture factory suddenly felt a gust of wind blowing away the heat and irritability.

Mo Yifei said happily: "It's a success. Fans must be installed here, here, and here."

When Du He came to the scene, Mo Yifei had already ordered the craftsmen to install two fans. Looking at the workers, not only did they not suffer from heat stroke, but they were all full of energy, discussing the hydraulic fans from time to time. "

Du He said with a smile: "I didn't expect that this chick is so capable, she is worth cultivating."

If it wasn't for Mo Yifei's unknown background, he would have planned to keep this female scientist.Although the R&D center is supported by Lao Yuan, Lao Yuan is a Taoist priest after all. Many times, he still uses metaphysics to do things, which made Du He speechless for a while. For example, the grenade secretly manufactured by the R&D center, Lao Yuan insisted that , it will not be misfired after the symbols are drawn on it, and the triangular army thorns will not last until they are soaked in boy urine, both of which make Du He dumbfounded.

With Mo Yifei's help, Du He saved a lot of trouble.

So he was not idle.

At noon, he brought seven or eight craftsmen to the courtyard of the R&D center, and asked them to drain all the water in the pool in the center of the courtyard, and then brought water from the Bahe River to fill it up.

Afterwards, Du He found a huge bath bucket.

I cut down a lot of bamboo, cut the bamboo into sections and cleaned them, filled the pillars with water, and inserted a small stick.

Finally, put more than 100 knots of bamboo into the bath tub and wrap it with black cloth.Two large stones are tied to the bottom of the bath barrel and sunk into the pool.

Yuan Tiangang, Mo Yifei, Li Yuanshu and others were all stunned by Du He's actions.

Some people even thought that Du He was going to take a bath here.

After all the preparations were done, Du He said, "Come here, pour all the saltpeter in."

The craftsman next to him hurriedly poured the three big boxes of saltpeter prepared in advance into the pond.

Only the sound of puffing and puffing can be heard.

Pieces of saltpeter, melted in water.
