The dawn in the east weaves a colorful picture into the sky.
The sky is blue, with light blue on both sides, like a clear sapphire.
The colorful morning glow is like a shining golden sword or a beautiful ribbon, dragging the sun up high.
The rising sun rises in the east, but it rises a little early in the summer.
Wang Zhi really wanted to sleep in, because he slept late yesterday, so he was pulled up by Cheng Chumo.
According to what he said, warriors must strictly demand themselves, and do their best every day.
You must practice martial arts diligently and never let it go to waste.
Although Wang Zhi was reluctant, he was pulled up and was no longer sleepy, so he practiced with Cheng Chumo.
Cheng Chumo's path is wide open, and he probably has to follow his father's true legacy, and he can fight like a tiger with a set of boxing techniques.
Wang Zhi thought that he got up quite early.
Although he was pulled up by Cheng Chumo, after asking, he found out that his father Wang Qiang and Gao Shan had set off long ago, driving an ox cart.
Ever since Wang Zhi came back from the battlefield last time with a dozen cows, there was no shortage of cows at home.
When he went to the market, he would also use a bullock cart.
After class, Wang Zhi went into his hut and tried to see if he could make soap.
First of all, it seems that caustic soda must be used.
Unfortunately, Wang Zhi found out after asking Wang Li that there is no caustic soda at all, but there is soda ash for making steamed buns.
"How about making it yourself?"
Wang Zhi took out some soda ash from the kitchen, and then took some quicklime, put it in a wooden barrel, added water, and kept stirring.
"Brother, brother, you know magic."
Cheng Chumo opened his mouth in surprise, and the expression on his face was indescribably weird, because he saw that as Wang Zhi kept stirring, stones appeared in the bucket.
Wang Zhi heard it a little funny.
This was just a simple chemistry experiment.
All junior high school students in future generations should know it, except for those guys who sleep in class.
In the Tang Dynasty, there were still many Taoist priests.
After all, Taoism was considered the state religion.
When many Taoist priests were refining elixirs, by chance, some chemical reactions would occur.
These people did not understand what was going on.
In order to show their extraordinaryness, they would often Brag about what powerful spells you have learned.
These alchemists are still very complacent, thinking that they know something that no one else knows, and then they give these miraculous medicines some magical names, such as Great Return Pill, Flying Fish Pill, etc.
However, Wang Zhi is very disdainful about the ingredients, because there are many things in it that can kill people, such as mercury, lead powder, etc.
Moreover, these elixirs will be exaggerated, and even the rumors become more and more outrageous.
For example, there is an elixir of immortality in Penglai Immortal Island, and the elixir of the Queen Mother of the West in Kunlun Mountain.
"What magic?
I'm making something, don't disturb me."
Wang Zhi's dissatisfied correction could not make others think that he was a stickman.
Ignoring Cheng Chumo's mutterings and talking to himself, Wang Zhi picked up the barrel, poured out the clear part, and then poured out all the sediment at the bottom.
The clear part is the caustic soda solution.
As long as it is heated and evaporated, the caustic soda can be obtained.
Wang Zhi was a little angry.
He couldn't remember part of it clearly.
This also shocked Wang Zhi.
It seems that the current life has a great impact on the past memories.
Although he remembered some things last time, it seems that It's still not enough.
Take the time to write down everything you know and can use.
Otherwise, after a few years, although you won't forget it, your memory will only be blurred.

"I have soap at home.
Otherwise, I can secretly bring it to you."
Cheng Chumo volunteered after learning that Wang Zhi planned to make soap.
"I don't want it.
I'm afraid your family doesn't have a lot of pancake.
As long as I succeed, I can have as much as I want, hehe."
Wang Zhi also got up when he saw Mrs.
Wang Li washing clothes and using plant ashes.
Moreover, Wang Zhi observed for a few days and found that everyone was basically using plant ash to wash clothes.
Plant ash contains potassium carbonate, which has the same effect as soda ash and can remove stains.
Who hasn’t used plant ash yet?
Besides, in ancient times, soda ash was all natural and not synthetic.
Moreover, soda ash chewed clothes very hard.
If the amount was not controlled, the clothes would no longer be wearable after a few times.
Otherwise, there would be several holes.
There is also honey locust powder, which is also one of the main decontamination products.
This thing mainly grows in the Yellow River Basin.
Later, more people moved south and there was no need for honey locust powder.
So, it was discovered in the Yangtze River Basin.
A fruit called soap seed is even more effective than honey locust.
As for the soap, it can only be used by some high-ranking officials, and ordinary people have never even seen it.
There is also a lot of wild boar meat at home, which Cheng Chumo and Ada fetch from the mountains when they have nothing to do.
Wang Zhi took out the thick fat and put it in a pot to make lard.
Watching the fat pork turn into lard little by little, Wang Zhi took up another large pot, poured half of the caustic soda solution he had just made into it, and then started to heat it.
Wang Zhi took a spoon, scooped out lard from another pot, poured it into the solution, and kept stirring at the same time.
When alkali and fat are heated, a saponification reaction will occur, the fat will gradually disappear, and a thick layer of viscous liquid will form at the bottom of the pot.
Wang Zhi scooped out a little bit with a spoon and looked at it, and found that there was still a little grease, so he added a little bit of caustic soda solution and continued to burn until all the grease disappeared.
Among these viscous liquids, there is the soap that Wang Zhi wants.
However, the current situation is that the soap is mixed with other things and dissolved in the water.
They must be separated.
Wang Zhi added soda ash little by little, kept stirring, and heated it.
The sodium ions in the soda ash would force the soap to separate from the water.
Soon, the soap liquid gathered above the solution.
Wang Zhi was stunned for a moment before he started the salting out process.
At this time, a thick layer of light yellow, translucent solid appeared.
This was the soap Wang Zhi wanted.
However, at this time, the temperature of the soap is very high, it is in a semi-solidified state, and it is soft.
His father was a carpenter and there were a lot of wooden boards at home, so Wang Zhi found four boards of suitable size and put them into a square, and then put all the soap liquid into the grinding tool.
"I'm still not fully prepared this time," Wang Zhi said with emotion.
Sometimes there are many things that you can't think of and can only think of when you use them.
But with this experience, next time it will be much better and faster. , after all, it is the first time, and there are many uncertain factors
