“

Unlocked the lid on the pottery jar, soaked for more than a month and soaked in the sky. The two of them were caught off guard and felt sour. Taining covered his beautiful nose and turned his head and ran out, saying, "Good brother, I have to go and see my mother. Don't force me, at worst, I won't have to do it in the future..."

"Vomit..." This tastes really bad.

He shook his head and went out to call two little eunuchs, asking them to send these things to Chengxintang. He waved his robe sleeves and went to Chengxintang to click Mao.

Chengxin Hall is also on the east side, a small building complex extending from the imperial city. It is obvious that it has to pass through the middle area again. Li Yu took out a brocade plaster in advance to cover his nose, but found that all the filth in the toilet had been transported away. "The ancestors showed their spirits, these slaves are really diligent. I, Southern Tang, aren't right, the revival of the Tang Dynasty is hoped..."

Chengxin Hall occupied a palace that was bigger than several princes' residences. There was no way. Apart from collecting books, Li Jing loved Danqing and always despised the road goods he bought outside to be uncomfortable to use;

After Li Bing died, he simply asked Chengxintang to specialize in the production of imperial literary and ink. So the ink bureau, the first ink makers in history, occupied a large area. Other pen-making and paper-making personnel also had special yards. In order to cooperate with their work, he also transferred craftsmen from the Ministry of Works and brought several Taoists from Xuanzhen Temple in Zijin Mountain to provide technical support;

Taoist priest, it’s all right to refine alchemy. The observation of heat and the analysis of minerals are now considered first-class.

These people couldn't get idle, so they asked Feng Yansi to set up two yards for them, so that they could practice their own craftsmanship when they were free.

Feng Yansi is still generous in this, so he is naturally accurate in everything.

"See the Imperial"

"See the Imperial"

All the craftsmen and eunuchs saluted him along the way. They all knew the news yesterday that the Anding Palace will now be their immediate boss from now on.

"Wait, because of Taoist priest, what's wrong with you?" Li Yu saw a middle-aged Taoist priest saluting him, but lowered his head and did not dare to look at him. After a closer look, his face was filled with bubbles, and the Taoist priests all had long hair. At this moment, his head was bare, and even his eyebrows were gone after looking closely...

This is from an acquaintance, Xuan Zhenguan, and he has a good temperament. Li Yu reads various Taoist classics without any trouble. When he encounters a place he doesn't understand, he will gain something.

"This, this..." I couldn't speak because I was stammering for a long time.

The other Taoist priests next to him held back their laughter and rescued him. "If you return the imperial edict, you will be furious because you used the fire method to kill the toxicity of sulfur when you use the fire method to kill the toxicity of sulfur yesterday, you will be furious by the fire."

"Oh... Is it okay? Have you ever asked the doctor from the Imperial Hospital to see you?"

"Xie Chengzhi cares, others are not seriously injured, just these eyebrows will not grow out for a while..." the little Taoist priest smiled.

Because his face turned blue next to him, he was an old alchemy expert. Such an eighty-year-old woman was so careless that she really lost her face.

"Well, be careful next time..." Li Yu waved his hand and asked them to retreat

Suddenly a thought flashed through his mind, "The method of subduing fire? What a familiar name, well, let me think about it. What did you say in "The Essence of the True Yuan and the Wonderful Dao" a few days ago, two taels of sulfur, two taels of salt, three taels of aristolochia, and minced them well, dig a pit, put them in the pot, and put them in the ground with the cooked fire... Isn't this gunpowder?"

Of course, the gunpowder produced by this method will basically not explode due to the formula ratio problem, but the combustion speed is extremely fast, so it is called gunpowder, not explosives.
