It wasn't dawn the next day.

Mr. Zhao got up early and went to see Mr. Xu's night fragrance... That's not!

Recently, he became obsessed with running because Zhao Shizhen in Kunshan asked Zhao Shixi to bring him a pair of running shoes.

What, you ask where Xiwa came from? That day, he tied his hands with Mr. Liu's son and was the one who was the piano boy for Zhao Hao.

Speaking of this pair of running shoes, the upper is soft and delicate calfskin, and the cutting stitches are perfect. A pair of 'Zhao' characters are embroidered with gold thread on the upper, which is very cool.

But what really excited Mr. Zhao was that the black soles of this pair of shoes were made of Eucommia glue!

When making hot air balloons in Beijing, Mr. Zhao discovered that the craftsmen who made Aoshan lamps would use a special glue and brush it on the silk skin after heating it, which could release water and flame retardant and make the silk not breathable.

At first he thought it was fish bladder glue, but after asking the craftsman, he learned that the main raw material of this glue was actually extracted from the bark of Eucommia ulmoide.

This made Mr. Zhao ecstatic. He always thought that the rubber industry of the Ming Dynasty would not start until his tentacles reached the Southeast Asian region.

But I forgot that there is a substitute for Daming - that is Eucommia Gum!

As the name suggests, this gel is produced from the precious medicinal herb that specializes in treating kidney deficiency and pain.

However, the leaves and bark of Eucommia ulmoides contain a large amount of Eucommia ulmoides with the same chemical composition as natural rubber.

However, the molecular structure of Eucommia ulmoides and rubber is different, which leads to the natural Eucommia ulmoides having no rubber elasticity and is like a piece of hard plastic.

As a fan of "Adopting Science", Mr. Zhao still remembers how to deal with Eucommia ulmoides. That is vulcanization.

Depending on the degree of vulcanization, natural Eucommia ulmoides can be either elastic rubber or hard plastic. This soft and hard characteristic is called "rubber-plastic duality".

The simplest vulcanization is to put Eucommia gel and sulfur together and bake it on the stove!

Of course, Mr. Zhao doesn’t know what proportions, what temperature to bake, and what seasonings to add.

I can only leave it to my eldest nephew who loves research to explore.

It has only been three months since Zhao Hao put this project in handing over to Zhao Shizhen.

Moreover, my eldest nephew was addicted to making guns later, otherwise he would definitely come out faster.

~~

Mr. Zhao is looking forward to the effect of this historic running shoes, which can be equivalent to that of the Jiefang shoes of the 1970s and 1980s.

Unexpectedly, after stepping on the ground, it was extremely elastic and very soft, which was much beyond his expectations.

Maybe I have forgotten how I feel when wearing sports shoes. Anyway, Zhao Hao felt that his feet were wrapped, soles of his feet were protected, and his knees were buffered. I'm really sorry for these shoes if I didn't run.

When he was wearing a shorts made by Qiaoqiao and ran out of the camp with Gao Wu, he heard a clanging sound behind him, and a pungent smell.

Following the smell, he turned to see that Mr. Xu was struggling with difficulty and staggering out of the barracks behind him.

There was a string of iron hooks hanging beside the car, and most of them were collected urine buckets and chamber pots.

At present, more than 2,000 reinforcements were taken by prisoners on the island, and the camp was almost full. The original house was not enough, and there were even more tents.

Jinke, who is responsible for the order of the entire camp, is strictly prohibited from urinating anywhere. He must go to the toilet in the cottage during the day and use a toilet at night. Violators will be whipped and served.

This was not Zhao Hao's request. Mr. Zhao always let Jin Ke do it by himself.

This is the regulation brought by Jin Ke from the Qi family's army.

Qi Jiguang found that as long as the soldiers are not allowed to drink raw water and maintain good personal hygiene, they can greatly reduce the number of people suffering from illness in the military. Naturally, corresponding requirements appeared in his military rules.

After Tong Zigong repeatedly beat dozens of prisoners and militias who violated regulations, no one dared to urinate or defecate anywhere, and even the discipline in other aspects improved a lot.

Zhao Hao covered his nose and was about to run away.

Suddenly, behind me, Xu Kun's hoarse shouting sounded.

"Mr. Zhao, I am willing to give you ten thousand taels of silver, can I let me go?!"

Zhao Hao turned around and ran away backwards while saying:

"I will give you 20,000 taels of silver. Can you continue to spend a year?"

Tong Zigong, who was about to kill for thousands of years behind Xu Kun, couldn't help but raise his hand and said, "Young Master gives me 20,000 taels, and my subordinates are willing to spend ten years."

"Haha, I'll consider it." Zhao Hao rolled his eyes secretly. Why is this guy so hard to look at the atmosphere?

"Mr. Zhao, please give me a good word. How can I let me go?" Xu Kun said sadly again: "I can't live such a day."

"It depends on your performance. If you perform well, you can let you go home for the New Year. If you perform poorly, just spend your whole life on Xishan Island..."

When Mr. Zhao ran to the camp gate, he suddenly stopped moving forward and laughed loudly, "By the way, it's not impossible for you to go back immediately."

"Ah, young master, tell me!" Xu Kun was so excited when he heard this. Although he had only been with the toilet for a few days, he felt that he had died in a sense.

He is willing to exchange all his wealth for opportunities for freedom and rebirth.

"Let your brother come and take care of you."

Mr. Zhao left the sentence that was so angry that he was not worth his life, turned around and ran away without a trace.

"I, I knew you were a bad person..." Xu Kun's angry curse stopped abruptly, and a "screaming" scream rang through the barracks.

~~

After Zhao Hao ran out of the barracks, he went north to Yuanshan and ran along a black road towards Jinduo River.

This path was originally available, probably built by the original islanders.

The day after going to the island, Mr. Zhao organized a large search team of 100 people to go into the mountains to find bandits... Well, it was actually going to find coal.

There is no coal and only limestone. Boiling cement is a delusion because the temperature cannot be reached.

Although I know that the coal mine here is definitely visible on the surface, Xishan Island is so big that Mr. Zhao is ready to not find coal for a month.

But who would have thought that as soon as I bypass Yuanshan, I would see this dark road.

Mr. Zhao saw that the road looked so familiar. When he grabbed a handful of black stones, he saw that it was indeed coal gangue...

Then he and the search team followed the gangue road to Jinduo River. After taking a boat to cross the river, there was a gangue road on the other side.

Continue north along the road several miles and you will see the black coal fields at the foot of the mountain...

The search ends.

~~

Zhao Hao originally thought that the residents on the island had a history of using coal.

But later I asked Mr. Liu to find out that although the people in the West knew that these coals could be burned, they had never used them.

Because it is the Jiangnan with lush grass and trees, there are endless firewood and charcoal that can't be burned. Who would have thought about using choking and dirty coal?

Cooking doesn't require that high temperature...

The reason why people dig up coal fields is to use coal gangue to pave the road, but all the real coals are abandoned like worn-out shoes.

It seems that there is no chance to do a coal lotus business in Jiangnan, which makes Mr. Zhao feel a little worried.

Fortunately, the industrial coal used for burning cement, bricks, and even iron smelting finally came to an end, which made Zhao Hao feel very comforted.
Chapter completed!
