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

Yang Guang beckoned his subordinates to come and prepare to extinguish the fire, but Sun Simiao stopped everyone: "The old man is prepared, the fire can't be lit, the smell of smoke is big, just wait until the smoke clears and then enter to clean it." ”

"Mr. Sun is experienced and well prepared."

Sun Simiao sighed helplessly: "Alchemy is always a bit risky. ”

"The technique of the elixir golden stone, Mr. is good at it, but I don't know this blasting technique, does Mr. have research?"

"What is this thing doing studying it?"

"Mr. is wrong, you can avoid it if you study it clearly, you always want to explode because something is mixed together, it won't be said that it will explode for no reason, figure out what is mixed with what will explode, it would be nice not to mix it next time."

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

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

A protective layer was piled up with stones on the side of the exploded medicine pod, and Sun Simiao's explosion experience was really rich.

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

"It's brimstone, and saltpeter, and every time these two things come together, there's a chance of exploding."

Yang Guang suggested: "Mr. Sun, why don't we try it, put sulfur and saltpeter together, and add some charcoal to ignite it, and see if it will explode. ”

"How can you say that you don't need it, you don't need it, sulfur and other highly toxic gold and stone drugs must be taken with fierce fire before they can be used in medicine."

Sun Simiao is limited by the mainstream views of this era, and has been trying to find a way to find a way to elixir from ancient books.

"Sir, do you take these pills yourself?"

"Don't eat it."

"Why?"

"It doesn't look like a good medicine."

"Then you still refine?"

"I believe that the real treasure medicine will be refined, the mystery of old age, sickness and death in life is hidden in the elixir, you see that the sulfur saltpeter mixture will explode, so what about adding other things, will it have other effects?"

Sun Simiao is a strong man of more than 1.9 meters, but he has an extremely rigorous scientific research spirit, but he has taken the wrong road, how many emperors have died on the pill, the Chinese pill technique is the same as the Western alchemy, which is not shallow, but he has made a lot of contributions to science, and on these two roads, there are countless scientists who have gone forward and carried forward the past.

Yang Guang chatted for a few words and left, he had to let Sun Simiao study for a while, and it was not good for him to come up all at once, it was not natural enough.

I took advantage of the noon to eat some food and went to Daxing City.

Yesterday's accident, but today Daxing City has already started, and 50,000 people have begun to get busy at the address of Daxing City.

Yu Wenkai divided 20,000 people to build the imperial palace and the imperial city, and the rest of the people were digging the ground, and according to the plan, the place needed for the sewage pipeline was dug out first.

It takes a lot of manpower to manage so many people, and on the first day, all places are not skilled enough, so Yu Wenkai is busy.

"Yu Wenkai, what about the pipes needed for the pipeline?"

"Your Highness, the construction of the large canals in several centers is complicated, and now the ground is broken first, and the brick walls must be built underground like palaces, and the rest of the pipes and 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, so the pipeline can not be buried too deep, about half a meter above the ground, in order to consider its circulation, for the highland direction is very elegant, Yu Wenkai designed these in.

"Bricks, isn't it enough?"

Yu Wenkai nodded: "Yes, a large number of bricks are needed, and at present, Weichen has calculated the quantity, and the supply is insufficient." ”

"I'll do this, and I'll give me a part of the craftsmen who make masonry."

"Yes, Your Highness."

In fact, there is no need for Yang Guang to care too much about the construction of things, in history, Yu Wenkai built the main body of Daxing City in nine months, and now the underground pipeline has been added, but the time has also dragged on to a year and a half, he should be able to do it, all he has to do is just like wood, bricks, these just needed materials let him not worry, do his own logistics work, and make money from the sale of houses in Daxing City.

Yang Guang ordered someone to call Li Yuan again.

Li Yuan hadn't reacted when he came to Daxing City, what Yang Guang was going to do.

Yang Guang took Li Yuan's hand, and said as if sympathizing with his old friend: "Cousin, look at this place, there are tens of thousands of people working in the mighty world, and in the future, a large city that has never been built before will be built as the imperial capital of the Great Sui, you can enjoy what kind of scene it will be like in the future." ”

Li Yuan stood on the tower of the overseer and looked at the vast area and admired: "Heavenly work, heavenly work." ”

"Cousin, I'm now in charge of supervising the construction of Daxing City, there are not many people who can be trusted, and I'm so busy that I don't even have time to sleep, cousin, you must come to help me."

"I ...... I...... The ability is limited, and I don't know how to build a city or how to help His Highness, but I am afraid that I will delay His Highness, but I still can't. ”

"Cousin, the old lady and the queen mother are sisters, this is also what the queen mother means, there is no need to refuse, cousin don't worry, from simple to complex, I will let my cousin take care of the brick factory first, and supervise the brick manufacturing thing, just cousin, don't think it's good to bury it."

Li Yuan's heart moved, and he seemed to think it was good, so he said: "Then I won't shirk it, thank you Your Highness." ”

Yang Guang patted Li Yuan's shoulder very familiarly: "Cousin, don't be so polite between you and me in the future, it's too much, let's go, I'll take you to have a look." ”

took Li Yuan to the place where the bricks were made, and then introduced: "Because Daxing City needs a lot of bricks, and even when I build houses in the future, I plan to use bricks, so I have to improve efficiency." ”

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

Li Yuan had never seen this kind of thing, so he listened carefully to Yang Guang's explanation: "After the soil is sent, the person responsible for mixing the soil is responsible for this project, the transportation is transported, and the topography is the topography, and finally I have to build several large-scale firing houses to produce bricks quickly and in large quantities, in fact, the process is not difficult, and it is necessary to maintain order and efficiency." ”

Split steps to speed up the process.

In fact, the craftsmen of this era are very particular about manufacturing, especially the bricks used in the Imperial City of Miyagi, the quality, modern craftsmanship are difficult to reproduce, but the bricks and stones buried in the ground to build sewage pipes do not need to be so elegant, and the practicality is the mainstay.

Yang Guang whispered to Li Yuan: "Cousin, don't underestimate bricks and stones, I have a plan, in the future, the houses will also use bricks and stones to make a part, of course, this has to be improved in technology, if it is feasible, the city can make a lot of money by relying on bricks and stones, you can understand what I mean." ”

Li Yuan thought for a while, and finally nodded: "Your Royal Highness the King of Jin, rest assured, I will do my best to manage the manufacture of masonry and leave no mistakes." ”

"I'm relieved to have my cousin here, and I'm relieved to have you in the brick factory."
