Now, Cao also knows that she has gone too far. Today, she wanted to take Li Zhonghao to beg Li Zhongyi, but unfortunately, Li Zhonghao has been firmly targeted by Li Dahe in the study.

The situation was extremely urgent, and Cao couldn't hesitate anymore, so she had to come to Li Zhongyi alone.

Li Zhongyi sensed Cao's hesitation, stood up and said, "You think about it carefully, if you think about it, you can take 20,000 yuan back to Cao's house." ”

After that, Li Zhongyi supported the mixed Aunt Xue and went back to the back hall directly.

Before leaving, Li Zhongyi glanced at the bottle, and the bottle nodded heavily, which means that she will definitely stare at the Cao family and prevent her from making a demon moth.

After returning to the East Chamber, Aunt Xue asked Li Zhongyi worriedly: "Da Lang, you forced the Cao family to leave, in case she can't think about it for a while...... So what to do? ”

Li Zhongyi smiled slightly, and asked Aunt Xue: "Ah Niang, what kind of person do you think the Cao family is?" ”

Aunt Xue thought about it carefully, shook her head and said, "She is used to living a good life, and she is definitely reluctant to die." ”

"Well, although the Cao family is vicious, Erlang is still surnamed Li after all." Li Zhongyi sighed and said, "No matter what, the child has to think about Grandpa." ”

Aunt Xue smiled with relief: "Your grandfather is a cold-faced and warm-hearted person, you are so affectionate and righteous, I am really happy to be a mother." ”

After about an hour and a half, the bottle came to report, Cao Shi signed the letter of separation in front of her, and then hired a carriage carrying three boxes of copper coins, and cried.

"Alas, it's unbearable to say, the Cao family also did it himself......" Aunt Xue is kind-hearted after all, and she is a little unbearable in her heart.

A big stone fell in Li Zhongyi's heart, Cao's problem was solved, and the housework came to an end.

In the evening, when Li Zhongyi was taking a sauna in the Hou Mansion in Chengdu, he told Meng Renyi about the matter, Meng Renyi didn't say a word, and immediately ordered someone to take his token, go to the prison and release Cao Meng, and restrict him to get out of Chengdu immediately and return to Wanzhou.

In this way, a scandalous housework that is likely to turn the world upside down and become a miasma was quietly settled under the joint efforts of Mrs. Zhao and Meng Renyi.

According to the servants at home, after Li Dahe learned the news, he was bored all day long, but he didn't say anything. It's Erlang Li Zhonghao, who cries and cries all day long, and he is reprimanded by Li Dahe.

For the sake of Li Dahe's face, Li Zhongyi passed the word and said that the Cao family was unwell and went to the countryside to recuperate.

Time flies, Mrs. Hua Rui's skin disease has been cured, and the alchemy that Meng Chang has always been thinking about is finally on the agenda.

On this day, Li Zhongyi fasted and bathed completely, wearing a blue robe, a hosta was inserted horizontally on the bun, and between walking, the robe was lightly brushed, looking like a fairy wind and bones.

Under the escort of Huang Qing and his people, Li Zhongyi climbed to the top of Qingcheng Mountain by car.

In a certain cave on the top of the mountain, someone had already arranged it according to Li Zhongyi's requirements.

In the cave, there are all kinds of alchemy utensils such as Dan furnace, Dan Ding, water sea, pomegranate jar, etc.

Li Zhongyi also ingeniously built a small charcoal kiln next to the cave, and connected a thick iron pipe to the mouth of the kiln, and the iron pipe was directly inserted into a large water tank, and the water tank was placed in the inside of a pool.

For the sake of safety, Meng Chang sent hundreds of Jin Wuwei's officers and soldiers to surround the entire cave mansion.

According to the calculated time, Li Zhongyi stood in front of the door of the cave, stood against the wind, lit the yellow talisman that had been made in advance, and strung it on a seven-star sword inlaid with gems, and chanted the words in his mouth, "my-ife-and-my-son, I-LoVe–you......"

Huang Qing was standing not far behind Li Zhongyi, but he couldn't understand what the hell Li Zhongyi was reading.

The good day has arrived, Li Zhongyi pretended to be a ghost and lit the alchemy furnace, randomly stuffed some medicinal materials into it, closed the lid, and left it alone.

Huang Qing was very puzzled in his heart, and when Li Zhongyi was done, he quietly came over and wanted to ask what was going on.

Who knows, Li Zhongyi just smiled mysteriously and did not answer his question.

In this era, except for scholars or scholars, most of the uneducated people generally believe in the existence of ghosts and gods.

Since Li Zhongyi was reluctant to say it, Huang Qing was worried that he had alarmed the gods and leaked the heavenly secrets, so he didn't dare to ask more.

For the next few days, Li Zhongyi tinkered with the charcoal kiln and the sealed pool.

The charcoal was cut into very neat pieces, and this work alone took the potter two days.

When it was time to put charcoal in the kiln, Li Zhongyi kept standing by the kiln and pointing, and if he made a slight mistake, he would ask to start again.

This tossed for another two days, and after the preparations were ready, Li Zhongyi asked the potter to light the charcoal kiln.

After the fire was lit in the kiln, black smoke began to emit from the iron pipe that served as the flue after about an hour.

Li Zhongyi instructed the handymen to start pouring clean water into the pool, and when the water was about a foot away from the large water tank, he decisively stopped.

At this time, white smoke began to rise from the iron pipe flue, and Li Zhongyi just watched quietly. When the yellow-brown gas came out of the flue, Li Zhongyi sniffed slightly, and felt that the smoke was extremely stimulating, so hot that he wanted to shed tears, and he immediately ordered more than a dozen handymen to take turns to carry water and pour water on the iron pipe that served as the flue to cool down.

Soon, a yellow-brown liquid with a strong sour smell dripped from the iron pipe, and flowed into the large water tank.

At this time, if there is a brother who understands chemistry, he will immediately point out that Li Zhongyi is preparing wood vinegar by the method of dry distillation in a charcoal kiln in Tongguò.

Two days later, the wood burning in the charcoal kiln was extinguished, and a large tank full of yellow-brown wood vinegar had been collected in the large tank.

After the iron pipe gradually cooled, Li Zhongyi found more than a dozen big men and asked them to carry the vat full of wood vinegar out of the pool.

Li Zhongyi walked to the side of the tank and looked at it, and now a thick layer of wood tar floated on the surface of the liquid, so he asked people to bring a water scoop and scoop out the wood tar.

Limited to the chemical methods of this era, there is only a very small residue of wood tar left in the vat, which is really impossible to remove.

After the wood vinegar was decoched, Li Zhongyi nodded, and ordered someone to bring the calcined natural limestone, and the quicklime obtained was added to the tank in large quantities, which was the neutralization reaction.

The wood vinegar with quicklime turned dark purple at first, then dark black, and finally purple red, and a large amount of foam appeared on the surface of the liquid in the tank.

"Okay." Li Zhong Yixun called a halt and asked the vat to be lifted onto the wooden platform that had been erected in advance. At the bottom of the wooden table, a large wooden barrel was prepared, and the mouth of the barrel was wrapped in layers of fine fabrics such as linen and silk, and more than a dozen layers were wrapped.

"Scoop out the red water and pour it into a wooden bucket." After Li Zhongyi gave the order, he walked to Huang Qing's side and said with a smile, "Huang Gong, thank you for your hard work." ”

"Brother Xian, Brother Fool really doesn't understand, what are you doing here?" Huang Qing blinked his eyes and glared at Li Zhongyi.

Li Zhongyi smiled shallowly, and said in his heart, even if I sue you that this is preparing vinegar stone, do you know what vinegar stone is?

Seeing that Li Zhongyi still refused to speak, Huang Qing's curiosity was almost bursting, he had seen countless immortal alchemy pills in the palace, and he had never seen such a method as Li Zhongyi.

Li Zhongyi drank tea leisurely, and when he saw that the time was almost up, he instructed the handymen to pour the filtered liquid into a large iron pot, heat it over slow heat, and then stir it constantly, and at the same time scoop off all the tar that came out of the surface.

After doing this for more than two hours, the liquid in the pot gradually turned into a gray solid, which is the calcium acetate that Li Zhongyi needs, that is, the acetate stone.

It was getting late, and Li Zhongyi ordered to stop work and resume work tomorrow.

After a good night's sleep, early the next morning, Li Zhongyi asked people to take out the ash (grass ash) and white carbon ash (quicklime) prepared in advance, set up a large cauldron, put both kinds of ash into the pot, and then add water, constantly add firewood and start cooking.

Huang Qing felt very strange in his heart, and couldn't help but run over and ask Li Zhongyi: "Brother Xian, what are you going to do?" ”

Li Zhongyi smiled slightly and said, "What are the materials for refining immortal medicine, please forgive the junior brother for not being able to say." ”

Huang Qing had a stomach full of questions, but he didn't dare to ask in detail, so he had to stand aside depressedly.

In fact, plant ash is a mixture of sodium carbonate (Na2CO3) and potassium carbonate (K2CO3), adding plant ash and quicklime and heating with water to obtain a mixed solution of sodium hydroxide (NaOH) and potassium hydroxide (KOH).

Sodium hydroxide, commonly known as caustic soda, also known as caustic soda, is an important industrial raw material.

In fact, this process is not necessary. Li Zhongyi just wanted to take such a good opportunity to verify the reliability of preparing caustic soda.

Because the solubility of sodium carbonate and potassium carbonate is different, Li Zhongyi successfully obtained sodium carbonate after steaming, cooling, and crystallization in the white porcelain ware prepared in advance.

Sodium carbonate is soda ash, also known as soda, which is not only an important chemical raw material for modern industry, but also an leaven for pasta.

In this era, because there is no leaven, the taste is far less fluffy, soft and refreshing than that of later generations.

It's a pity that because of the lack of raw materials, Li Zhongyi can only make soda through the method of guò real yàn room, and there is no way to produce soda on a large scale.

After the acetate and sodium carbonate were leveled respectively, Li Zhongyi was in a good mood, and in one more day, sodium acetate could be made.

This sodium acetate, as well as sodium carbonate, is one of the treasures that Li Zhongyi wants to completely fool Meng Chang this time.

For the first time, Li Zhongyi felt that the ancients didn't understand chemistry, which is really good!

That night, Li Zhongyi was in high spirits, and when he had dinner with Huang Qing, he drank two large jars of "daughter red" that resembled Xiaogan rice wine.

From the next day, Li Zhongyi began to pound all kinds of rare medicinal materials. The ancestral pills are mainly the "Turtle and Crane Pill" used to prolong life, the "Mighty King Kong Pill" which contains a lot of mercury, and the Detoxification Powder which is specially used to excrete heavy metal substances.

Out of symptomatic considerations, Li Zhongyi only planned to take out the "Turtle and Crane Pill" this time, because Meng Chang was cutting in the house every day, and he had to replenish kidney water to strengthen kidney yang.

Originally, the Turtle Crane Pill was not very easy to configure, but the good news was that Meng Chang's palace was almost equipped with all kinds of precious medicinal materials.

So, in the next two days, Li Zhongyi secretly made the turtle and crane pill according to the ancestral method, and waited for the critical moment to take it out and use it.

Meng Chang has been eating Yang Xianchang's so-called "elixir" for the past two days, and he is indeed much more powerful in bed, but this elixir is too violent, and even the words in the crotch of his pants have been warped when he went to the morning court, not to mention how embarrassing it is.

A month and a half later, when he heard that Li Zhongyi's elixir was about to be refined, Meng Chang was very happy, and in order to show his piety, he couldn't bear it that night and didn't ask a woman to accompany him.

On the second watch of the next day, Meng Chang left the palace early, and went straight to Qingcheng Mountain with a large team of high-ranking officials and forbidden troops.
