Traveling through Great Qin: Father Qin Shihuang!

After Zhao Yun arrived in South Vietnam, his first order was to strictly prohibit the local residents from cutting down rubber trees, and began to study the method of making raw rubber.

However, the yield of these wild rubber trees is not high, and the raw rubber that can be produced from each tree is nearly two-thirds lower than that of later generations of rubber trees.

Therefore, in order to meet the rubber consumption of Daqin, one must find a way to artificially cultivate rubber, and only after continuous optimization and cultivation can qualified rubber trees be cultivated.

But this is something to be considered later, Zhao Che will naturally carry out a series of experiments to bring these raw tapes back.

Rubber is a very significant research project for the Academy of Sciences.

Even including Daqin's current steam engine project, Daqin's only steam engine has emptied most of Zhao Che's family fortune, and finally made Daqin's first steam ship Xuanniao with it.

In the production process of the steam engine, the effect of rubber cannot be ignored.

Because the principle of the steam engine is to compress the heat generated and then convert it into power. In the process of compression, the internal sealing of the steam engine is very required. At present, only rubber can perfectly do this.

The status of rubber in the manufacturing industry is almost irreplaceable. Otherwise, Zhao Che would not have sent Zhao Yun to manage Nanjun for himself, and spend so much effort to extract these raw rubber.

"Notify me, prepare to make rubber!"

Zhao Che watched buckets of raw rubber being moved over, and after casually giving orders to Gong Shuchou, he walked towards the rubber-making laboratory.

Since the beginning of construction, Daqin Research Institute has prepared dedicated laboratories and production workshops in various fields.

It is obviously impossible to use raw rubber directly as rubber. In the process of making finished rubber, many basic processes need to be carried out.

Extracting raw rubber is the first step. Raw materials are prepared. After the raw materials are prepared, various additives need to be added. These are auxiliary materials to improve certain aspects of the finished rubber.

According to the different uses of the finished rubber, the auxiliary materials added are also different.

After adding the auxiliary materials, it is also necessary to add fiber materials, such as various artificial fibers such as cotton and hemp.

The raw rubber will solidify after being removed, so it needs to be softened at an appropriate temperature, and then blended with additives such as rosin paraffin to evaporate water and filter impurities.

After all this is done, the subsequent steps can be carried out to finally make a real finished rubber product.

Without the assistance of advanced industrial machines from later generations, it would take a lot of manpower and time to make rubber that can be used.

Considering that it was the first time for Gongshuqiu and the staff of the scientific research institute to see rubber, Zhao Che personally did it and taught them by precept and example.

Gongshuchou and the others stood aside, holding notebooks in their hands, and kept recording everything that needed attention during the rubber production process.

After seven days of work, Zhao Che finally completed the production of the first batch of rubber samples.

Looking at the small piece of black rubber in front of him, a satisfied smile appeared on the corner of Zhao Che's mouth.

With these rubbers, Daqin's industrial development progress will be raised to another level in the future.

"This is the finished rubber. You should have mastered the main points of it. This batch of rubber is used as your experimental supplies. I still have only one request. Master it as soon as possible, and then mass-produce it!"

Zhao Che casually handed the rubber block in his hand to Gong Shuchou, and then gave instructions to everyone.

"Young master, don't worry, the details you just taught are so detailed, we will be able to master them in a short time."

Gong Shuchou made a promise.

"Okay, I'm going to see my father!"

Zhao Che nodded, and then left with Yuhuatian and others.

The production of rubber is considered complete, and the next step is to consider how to mass-produce it. However, the production process of rubber is not very complicated, but due to the limitation of industrial machines, the output may not be very high.

For Zhao Che, the most troublesome thing is the production of raw rubber in South Vietnam.

The raw rubber transported by Zhao Yun this time almost emptied the entire South Vietnam, but it was not enough to support Daqin's rubber needs.

For Daqin to step into the industrial age, rubber is almost an indispensable basic material, and the current reserves in South Vietnam alone are not enough.

Before that, Zhao Che had issued a development plan for South Vietnam, but due to various reasons, it was temporarily put on hold.

For Zhao Che, there is an opportunity in front of him to vigorously develop the entire southern part of Daqin, including Nanyue.

The climatic conditions in the south are their greatest advantage. It is rainy and the climate is humid and warm, which are the most suitable innate conditions for the growth of crops and plants.

The first batch of hybrid rice was sent to South Vietnam long ago, and it has been successfully cultivated in South Vietnam. Now Zhao Yun has slowly started to promote the hybrid rice.

Zhao Che was thinking about his plan, and the carriage had already arrived at Xianyang Palace.

After arriving at Xianyang Palace, Ying Zheng went straight to the Imperial Study Room. Ying Zheng and Fu Su had already received the news that Zhao Che wanted to discuss important matters with them, and they were already waiting in the Imperial Study Room.

"Father, brother!"

Zhao Che entered the imperial study room, dismissed the Jinyiwei behind him, and greeted Yingzheng and Fusu.

Not seeing him for a while, Fusu's whole demeanor now seems to be a different person.

In the past, Fusu wore a Confucian shirt, behaved mildly, and talked extraordinaryly. He gave people the impression that a gentleman is as gentle as jade.

But after Ying Zheng taught and trained him hand in hand during this period of time, Fusu had the aura of a superior person, and most people would feel a sense of pressure standing in front of him.

But in front of Zhao Che, Fusu didn't put on airs, and when he saw him coming in, he greeted him with a smile.

"Brother Che, my father and I heard that you have been researching that rubber in the scientific research institute for the past few days. You have worked hard these few days."

"It doesn't matter. Compared with me, elder brother has really worked hard. It is very troublesome to deal with so many government affairs in the court."

Hearing this, Fu Su said with a wry smile.

"It's more than troublesome. Now I can finally understand how hard my father has worked all these years as the emperor. The huge Qin Empire receives all kinds of memorials every day. If I handle them one by one myself, I'm afraid it will be tiring. I can't finish it even if I die."

"Elder brother doesn't need to do everything himself. There are still so many talents in the court. Elder brother only needs to grasp the overall direction. Otherwise, wouldn't the adults in my Daqin have to retire and return to their hometowns?"

Zhao Che casually laughed and walked to the desk.

There was a map of Daqin on the table. At this time, Ying Zheng was frowning and looking at the route on the map, as if he was thinking about something.

"Father, look here!"
