"Fifth Brother...what are you looking for?"

Li Mingda asked curiously as he looked at Li You who was constantly looking for it.

The location here is Li You's warehouse in Dunhuafang. There are various items brought back by Li You from the modern era, but they are basically items from the 1970s or 1980s.

Moreover, these items were not very abrupt when they were placed in the Tang Dynasty at this time.

"Just...just...just...just!"

Li You said three times in a row, but he just didn't know how to say it. What he was looking for was the cloth and propane that he bought for the hot air balloon that he bought for the second time...

Someone may ask, what to do when looking for this... Have you made a bet with someone?

Alas... Li You didn't have time to bet with others. He was so busy that he was busy not being harassed by the prince and the King of Wei, while he was busy with the construction of Dunhuafang. Finally, he had to do the tasks given by the ghost system in his body.

Finding the cloth and propane for hot air balloons is to complete the artificial rainfall task.

According to Li You's knowledge, the so-called artificial rainfall refers to the process of artificially supplementing certain necessary conditions for precipitation based on the principle of natural precipitation, which promotes the rapid condensation or collision of cloud droplets and expanding into raindrops and landing on the ground.

The method is to choose the right time according to the physical characteristics of different clouds, and use aircraft and rockets to sow catalysts such as dry ice, silver iodide, salt powder into the clouds to precipitate or increase the precipitation in the clouds to relieve or alleviate farmland drought, increase the irrigation water or water supply capacity of the reservoir, or increase the amount of electricity generation, etc.

Li You has no anti-aircraft artillery, nor does he have rockets or planes. How should Li You perform artificial rainfall?

Li You thought about it for a long time, and the meal was almost tasteless. Later... Li You suddenly thought of a hot air balloon. Although there was no plane, Li You could make a hot air balloon and then put the hot air balloon into the sky.

Buy some silver iodide from modern times... This silver iodide is a compound of iodine and silver, a yellow powder (558 degrees ~), decomposes light and absorbs heat a lot, first turns gray and then turns black, is insoluble in water and ammonia, and is used for photography and artificial rainfall.

Then he shot the clouds containing rain with a bow and arrow, Li You believed that it would be successful, because the silver iodide used by Li You was the best rain accelerator. Another important thing is that artificial rainfall was successful during World War II.

There were indeed planes at that time, but the height of the plane was not very high. As long as clouds could be found, it should be possible to release hot air balloons.

The first person who discovered that artificial rain could be caused was Xie Fu. He completed his experiment very early. It should be a cold day in November. Xie Fu and Langmuir saw a cloud appearing in the sky.

Xie Fu immediately boarded the plane.

He knew it would be possible to fly for a long time to find a cloud suitable for sowing dry ice. This is a huge gray cloud filled with water vapor. Xie Fu chose the right time and started the machine. The dry ice fell into the clouds like a dragged streamer.

Half of the spray was sprayed, the dry ice lowered the surrounding temperature, and the plane's engine was turned off. Xie Fu was quick to tell and immediately threw the remaining dry ice from the cabin window into the clouds below.

Dr. Langmuir, who was waiting on the ground, looked up at the white snowflakes floating down from the clouds, and was extremely excited. Xie Fu walked off the plane and was covered in cold cold. Langmuir cheered and ran over to meet him, shouting happily: "You have created a miracle in history!"

Xie Fu's experiments have indeed opened a new chapter in the history of human influence on weather.

From then on, scientists often flew over pastures, fields and mountains. They spread dry ice in the clouds, allowing the crystal raindrops to moisturize the roots of the thirsty plants.

However, after this Fu discovered that the freezing method could form artificial rain, he no longer sought painstakingly to find substances that could form the center of the water droplet.

Later, a scientist named Bernard von Nigut was not satisfied with Xie Fu's conclusion.

Just as the young Xie Fu was determined to explore unknown things at the time. He believed that Atkin's conclusion that there are fine particles in the center of raindrops was well-founded. He looked up a lot of information, hoping to find a chemical that is suitable for the formation of water droplets or the center of ice crystals. Von Nigut finally chose silver iodide.

Once silver iodide rain accumulator was used, it quickly gained a wider application than dry ice; because silver iodide was easily launched from the ground into the clouds with a simple device, which was not as troublesome as using dry ice. Using dry ice was sometimes a bit dangerous. Several times, huge dry ice fell straight into the roof and was chiseled into large holes, causing panic.

After the two of them had decided on their deeds, Li You thought of using a hot air balloon to rise to the sky, and then shot a bow and arrow containing silver iodide at the cloud with water vapor. Although he didn't know if it would be successful, Li You believed that this should be the only opportunity for him to experiment.

But after buying the materials for hot air balloons, things became more and Fei Tian’s dream didn’t think about it. Li You now forgot to put the hot air balloon cloth in the warehouse.

This is not... Now I bring Li Mingda to the warehouse to look for it.

There are only a few people who have come in to this warehouse now, namely Li You, Li Mingda, Li Zhi, Quan Zhixi, Xiao Yan... etc. Others cannot come in, because there is strict protection here, and basically people will not be able to get close to this warehouse within a range of 100 meters.

"What's that..." Li Mingda looked at Li You stammeringly, with a hint of confusion in his little eyes: "If you don't explain it clearly, how can I find it for you?"

"It's the cloth I got back last time, the blue one. I didn't tell you that I wanted to use it for flying...!" Li You tried his best to explain.

"Ah...!" Finally, Li Mingda said 'ah' and nodded quickly, "I remembered it, Fifth Brother, you said you wanted to fly. At that time, I thought you were stupid, only Baoer was looking forward to it very much...!"

This person can't talk about people in broad daylight. Once they talk about people, they will arrive.

"Young Master..." Yaoyu stood at the door and said, "Di Renjie, Xiao Baoer, and Su Qingjie have come together and said that they have completed their respective homework. Please check..."

"Oh...they are here..." Li Mingda was happy and immediately prepared to run out the door. The four of them were a group called the Four Scammers in Dunhuafang. Of course, they did not think they were the Four Scammers, but called themselves the magicians in Dunhuafang.

This name was actually created by Li You.

On an extremely boring day, Li You directly caught Li Mingda by his side and said that he wanted to play a game for his beloved sister. The content of the game was seen by Li You on a modern video.

Tie a wooden box on your right hand, get something inside, then find three wooden boxes, grab one of the three wooden boxes with your right hand, and shake it. A sound will appear, but the sound does not come from one of the three wooden boxes, but the wooden box tied to Li You's right hand.

Then change the wooden box casually and ask others to guess which wooden box has something in it.

A consistent amount of money at a time.

My goodness, this is not simple... Li Mingda was almost laughing. She felt that her fifth brother had sucked his head and then came to give her money, but she didn't know that a big trick was waiting for Li Mingda.

The final result was that Li Mingda lost nearly a thousand stalemates from Li You.

That day, Li Mingda ran to Yin Fei's palace and cried for almost half an hour, saying that the fifth brother had cheated him of his money. His pitiful appearance led Yin Fei to bring people directly to Li You's residence. Not only did he take away Li Mingda's 1,000 guan, but he also robbed Li Mingda hundreds of guan.

Only then did Li Mingda get happy.

However, when Li Mingda wanted to know what trick Li You was playing, Li You didn't say anything. Seeing that the money was coming back, Yin Fei left herself and she had to go back to play mahjong.

But Li Mingda was too curious. What was stupid? He clearly saw it, but he never picked it up. He was so hateful that no matter how cute he acted, Li You just didn't tell Li Mingdong.

This made the little guy angry.

In the end, there was no way. When Li You was taking a shower, Li Mingda rushed in and looked at Li You who was huddling in the wooden basin and tremblingly protecting him with a towel.

Li Mingda’s request was very simple, just tell her how to do that magic?

Li You didn't want to say it, but he didn't expect that his old sister was so shameless, with a pair of black eyes, looking at herself in the basin motionless, making Li You feel furious.

Finally, under the strong mental pressure, Li You still confessed.

After knowing that this scam was just that simple, Li Mingda left with satisfaction. However, this trip made him the name of the four major liars in Dunhuafang.

Soon, Li Mingda gathered his three little followers together. Di Renjie, Xiao Baoer, and Su Qingjie claimed to be Li Mingda's most loyal dog-legged. These four people locked their first target on the sucker Li Zhi.

At first, Li Zhi was like Li Mingda at the beginning, thinking that his sister had sucked her head and gave her money. That was a ten-ton conglomerate at one time. Li Zhi smiled wickedly and wanted to take Li Mingda's ten-ton conglomerate.

But when Li Zhi picked up the wooden box full of information and shook it, his face immediately changed because he had no sound at all, so he made the wrong choice.

"Haha...haha..." Soon, the arrogant and crazy laughter of Li Mingda and others rang out next to him.

Li Zhi's self-confidence was hit because in the subsequent game, Li Zhi lost more than 10,000 yuan, from ten yuan at the beginning to one hundred yuan at the end and one thousand yuan at the end.

Li Zhi lost very thoroughly.

Originally, Li Zhi wanted to betray the debt, but Li Mingda might have expected that his strength was not good, so he called his three followers to his side, Xiao Baoer, Di Renjie, and Su Qingjie directly surrounded Li Zhi like this.

In the end, Li Zhi had no choice. After giving 1,000 guan, he gave 3,000 guan of flying money. The rest was written on IOU. If he didn't give it for a few days, Li Mingda would come to the door to grab it directly.

You don’t know how miserable Li Zhi cried when he saw Li You.
