Following Yang Guang's words, the elixir Sun Simiao refined today exploded.

Yang Guang called his subordinates to come and prepare to put out the fire, but Sun Simiao stopped everyone: "I am prepared, the fire will not start, the smoke smells strong, just wait until the smoke dissipates before going in to clean it up."

"Mr. Sun has sufficient experience and preparation."

Sun Simiao sighed helplessly: "Alchemy is always risky."

"Sir, you are good at the art of elixirs, metals and stones, but I don't know about the art of explosion. Do you have any research on it?"

"What's the purpose of studying this thing?"

"Sir, you are wrong. You can avoid it only by researching it clearly. If there is an explosion, it will always happen because some things are mixed together. You won't say that it explodes for no reason. Find out what will explode when mixed with what. Don't mix it up next time.

That’s fine.”

Sun Simiao looked at Yang Guang in surprise: "What His Highness said is absolutely true, wonderful, wonderful."

Yang Guang accompanied Sun Simiao into the messy room after the smoke dissipated, and smelled the strong smell of sulfur and the pungent smell after the explosion.

A protective layer was piled up with stones around the exploded medicine cauldron. Sun Simiao had indeed rich experience in explosions.

While cleaning, Yang Guang asked knowingly: "Mr. Sun, what is this pungent smell?"

"It's sulfur and saltpeter. Every time these two things come together, there's a chance they'll explode."

Mononitrate, disulfide, and charcoal, add some sugar to Da Yiwan.

The necessities of black gunpowder are sulfur, nitre, and charcoal. The ratio is one pound (sixteen ounces) of nitrate, two ounces of sulfur, and three ounces of charcoal, a rough ratio of 16:2:3.

Yang Guang then suggested: "Mr. Sun, why don't we try it? Put the sulfur and saltpeter together separately, add some charcoal to ignite it, and see if it explodes. If it does, then these three things are at work.

, just don’t need it in the future.”

"How can you say that you don't need to use it? Sulfur and other highly toxic gold and stone medicines must be subdued with fierce fire before they can be used as medicine."

Limited by the mainstream views of this era, Sun Simiao has been trying to find ways to find elixirs from ancient books.

"Sir, do you want to take these pills yourself?"

"Don't eat."

"Why?"

"It doesn't look like good medicine."

"Then you still refine it?"

"I believe that we will be able to refine a real treasure. The secret of life, old age, illness and death is hidden in the elixir. You see that mixing sulfur and saltpeter will explode. What about adding other things? Will there be other effects?"<

Sun Simiao was a tall man of over 1.9 meters, but he had an extremely rigorous scientific research spirit. He just took the wrong path. Many emperors died on elixirs. The Chinese elixir technique is the same as the Western alchemy, and it is very harmful.

, but they have made a lot of contributions to science, and countless scientists have followed these two paths to continue the past and the future.

Yang Guang chatted for a few words and then left. He had to let Sun Simiao study it for a while. It would not be good to figure it out all at once, as it would not be natural enough.

After having some lunch at noon, we headed to Daxing City.

It was an accident yesterday, but today Daxing City has started construction, and 50,000 people have begun to work on the site of Daxing City.

Yu Wenkai allocated 20,000 people to build the palace and the imperial city, and the remaining people were digging the ground. According to the plan, they dug out the places needed for the sewage pipes first.

Managing so many civilians requires a lot of manpower. On the first day, everyone was not skilled enough, so Yu Wenkai was very busy.

"Yu Wenkai, how are the pipes needed for the pipeline?"

"Your Highness, the construction of several central canals is complex. The ground is broken first. Brick walls will be built underground like palaces. The remaining small pipes have been ordered to be fired by the pottery factory."

Yang Guang nodded. Because the materials that can be made in this era have limited bearing capacity, the pipes cannot be buried too deep, about half a meter above the ground. In order to consider its circulation, the direction of the highlands is very particular. Yu Wenkai will

These are all designed in.

"Are there not enough bricks?"

Yu Wenkai nodded: "Yes, we need a large amount of bricks. Currently, Wei Chen has calculated the quantity and the supply is insufficient."

"I will take care of this matter and give me part of the craftsmen who make the masonry."

"Yes, Your Highness."

In fact, Yang Guang does not need to pay too much attention to the construction matter. Historically, Yu Wenkai built the main body of Daxing City in nine months. Now underground pipelines have been added, but the time has been delayed to a year and a half. He should be able to do what he has to do.

Just like lumber and bricks, which are just needed materials, he should not worry, do his own logistics work, and make money by selling houses in Daxing City.

Yang Guang ordered people to call Li Yuan again.

When Li Yuan arrived at Daxing City, he had not yet realized what Yang Guang was going to do.

Yang Guang took Li Yuan's hand and said like a sympathetic old friend: "Cousin, look at this place. Tens of thousands of people are working in this place. In the future, an unprecedented large city will be built as a large city."

The imperial capital of the Sui Dynasty, you can enjoy what it will be like in the future."

Li Yuan stood on the high tower of the supervisor and looked at the vast area and praised: "It's a God's work, a God's work."

"Cousin, I am now responsible for supervising the construction of Daxing City. There are not many people I can trust. I am so busy that I don't even have time to sleep. Cousin, you must come and help me."

"I...I...have limited abilities, and I don't know how to build a city or how to help His Highness. I'm afraid that I might delay His Highness and still not be able to do it."

"Cousin, the old lady and the mother are biological sisters. This is what the mother wants, so there is no need to refuse. There is no need to worry, cousin. From simple to complex, I will first let my cousin take charge of the brick factory and supervise the brick factory.

It will be fine if you can make a lot of money. Just don’t think that your talent has been buried, cousin.”

Li Yuan thought about it and seemed to think it was good, so he said: "Then I won't refuse. Thank you, Your Highness."

Yang Guang patted Li Yuan's shoulder very familiarly: "Cousin, don't be so polite between you and me from now on. It's getting ugly. Come on, I'll take you to see it."

He took Li Yuan to the place where the bricks are made, and then introduced: "Because Daxing City requires a large amount of bricks, I even plan to use bricks when building houses in the future, so I have to improve efficiency."

"Working like an assembly line, each worker only does one thing."

Li Yuan had never seen such a thing before, so he listened carefully to Yang Guang's explanation: "After the soil was delivered, the person responsible for stirring the soil was responsible for this project, the person responsible for transporting it transported it, and the person drawing the mold made the mold. Finally, what happened?

I want to build several large-scale firing houses to produce bricks quickly and in large quantities. In fact, the process technology is not difficult, and it must be kept orderly and efficient."

Split steps to speed up the process.

In fact, the craftsmen of this era were very particular about their manufacturing, especially the bricks used in the Miyagi Imperial City. The quality is difficult to replicate with modern craftsmanship, but the masonry buried underground to build sewage pipes does not need to be so particular. It is practical.

Sex is the main thing.

Yang Guang whispered to Li Yuan: "Cousin, don't underestimate the bricks and stones. I have plans to use bricks and stones to make part of the houses in the future. Of course, this needs to improve the technology. If it is feasible, the city will be able to rely on bricks and stones in the future."

Make a lot of money, you know what I mean."

Li Yuan thought for a while and finally nodded: "Don't worry, Your Highness King Jin, I will do my best to manage the manufacturing of masonry and leave no flaws."
