Li Zhi has almost no knowledge of exploration.

As a result, he has been supporting the development of the exploration industry for a long time.

He asked Duan Lun to come forward and invite many talents who had mastered exploration technology, and asked these people to cooperate with colleges outside the city to specialize in prospecting technology.

At this time, there were four groups of explorers in various parts of Datang who were carrying out exploration work at the same time.

In addition to finding and marking the location of mines, they also have to summarize and organize the process and experience of discovering these minerals at any time.

They can request tools and equipment according to their needs.

If the existing technology cannot meet their requirements, there will be people who will work on it.

When they find an ore they don't know, they will send someone to the academy as soon as they find it.

Li Su and others will conduct experiments according to the periodic table left by Li Zhi.

As soon as it is discovered that a metal can be used directly under the existing technology, a systematic study will be conducted.

Among them, the wolframite discovered not long ago brought a great surprise to Li Zhi.

Today, generators are already being used.

What Li Zhi is most eager to use now is electric lights.

With electric lights, Datang's power development can be quickly transferred to the direction of civil use.

In this way, it will enter a period of rapid development.

After Tang Jian left the Jin Palace, Li Zhi immediately went to the academy outside the city.

He was going to see the progress of tungsten research.

When he came to the academy, the first thing he paid attention to was the learning situation of the princes.

Although they are all the same age as Li Zhi, they are a group of real children.

So a lot of times they make mistakes.

Li Zhi, on the other hand, demanded that the teachers in the academy treat them equally.

As long as someone makes a mistake, they will be beaten and punished, and they will be punished, regardless of their identity.

Among these princes, Li Shen, the king of Shen who was the same age as Li Zhi, had already revealed his talent early.

He actually has a lot of research on astronomy and astronomy.

Li Zhi was quite supportive of his interest, and directly asked him to worship Yuan Tiangang as a teacher.

In addition, Li Zhi also introduced Li Shen to Li Chunfeng of Qin Tianjian.

Under the guidance of these two famous masters, Li Shen's progress in astronomy is very obvious.

It is important to know that astronomy is a very important discipline for aerospace.

If Li Shen's development is good, he may be able to become the leader of the aerospace industry in the Tang Dynasty in the future.

When Li Zhi came to the academy, these princes were doing experiments in the laboratory.

Teachers are teaching them how to make hydrogen and oxygen by electrolyzing water.

Li Zhi quietly stood behind several people and watched them do it one by one.

They all seemed excited to look at the way they looked.

When the teacher told them that hydrogen is very light and can make lighter objects float, Li Jian, the acting king, suddenly raised a hand.

When the teacher looked at Li Jian, he immediately asked, "Teacher, can hydrogen make people float?" ”

His question stunned the teacher, and then the teacher shook his head and said, "The teacher hasn't thought about this either." ”

Just when Li Jian felt a little disappointed, a voice suddenly came from behind him.

"Of course."

After hearing this, everyone turned around and looked behind them, and found Li Zhi standing there with a smile on his face.

Li Jian happily asked, "Is what Brother Jiu said true?"

If hydrogen can hold people up, why hasn't anyone done it before? ”

Li Zhi smiled: "It's not very troublesome to do, but it's very dangerous, and if it's not good, it will kill people." ”

After Li Jian heard this, he immediately lost interest in this matter.

He was still young after all, and he didn't want to try again when he heard that doing an experiment would kill people.

Seeing him like this, Li Zhi smiled and said, "Do you want to fly around the sky in the twelfth brother?" ”

Li Jian frowned and said, "The little brother wants to do it very much, but he is a little afraid of death."

My mother said that my little brother's life was picked up, so I wanted to live well. ”

Li Zhi stepped forward and grabbed Li Jian's shoulders and said, "As the saying goes, if you don't die in a big disaster, you will have a blessing in the future."

Haven't you been fine since you had a serious illness? ”

Li Jian said: "That little brother can't take risks knowing the danger!" ”

After hearing this, Li Zhi laughed and said, "Then Brother Jiu will accompany you on an adventure, okay?" ”

Li Jian hesitated for a moment and said, "Okay, my mother said that Brother Jiu is blessed, and it should be fine to follow Brother Jiu." ”

Li Zhi burst into laughter after listening to Li Jian's words.

Then he turned his head to everyone and said, "Do you want to see how my eleventh brother and I fly?" ”

Everyone was interested when they heard such an exciting thing, so they all said, "I want to..."

Yuan Tiangang, who was standing on the side, stood up at this time and said, "Your Highness, don't mess around.

This ability to fly has always been possessed only by birds.

Why would I, the human race, take the risk of such a dangerous thing? ”

Li Zhi said: "The reason why I, human beings, can rule all things is because I dare to think and dare to do.

If we lose the spirit of exploration, how can we promote human progress? ”

After saying this, he said to the people, "Brothers, wait for two days, and when I have everything ready, I will take you and others to witness the miracle." ”

After listening to Li Zhi's words, everyone cheered, and then left the laboratory with Li Zhi.

Li Zhi went to Li Su to look at the research progress of tungsten ore.

It was found that only preliminary smelting has been carried out today, and the process of purification and processing is still being studied.

After Li Zhi turned around, he hurriedly left the academy and rushed to the workshop that produced polyester.

He wanted to make a hot air balloon, so he had to choose a polyester fabric that was both light and strong.

Li Zhi asked the shopkeeper of the workshop to help him produce a batch of thickened fabrics.

In addition, Li Zhi also told him to dye the cloth and apply a layer of tung oil by the way.

After leaving here, Li Zhi came to Jiangzuojian again and asked Yan Lide to help him make a huge hanging basket and a bunch of accessories.

As for the most important fuel, there is natural gas in Li Su's place.

The next day, Li Zhi came to the Shaofu Prison with the fabric and some accessories.

The umbrella surface of the hot air balloon is a little difficult to sew, and Li Zhi trusts the workers here the most.

Two days later, everything was ready.

Li Zhi gathered a group of princes together and began to make hot air balloons.

Li Zhi and the others made a lot of noise, and soon attracted many people in the academy to come and watch together.

And in a group of curious female students, Wu Zetian is also impressively listed.

Because the accessories are well prepared, the speed of assembly is not slow.

But getting a hot air balloon into the air isn't something kids can do.

Li Zhi found a few of Li Su's students and asked them to help him inflate the hot air balloon and fill the gondola with a few cans of natural gas.

When everything was ready, Li Zhi came to Li Jian and said, "Are you ready?" We're going to heaven. ”
