"Mr. Guozi entered the Imperial College in the morning and recruited students to set up a lecture hall. The day he taught:"

When Li Erlang saw Nangong Qi walk out of the room, he closed his eyes and started reciting loudly.

"The skill of career is diligent, and it is wasteful; the action is accomplished by thinking, and it is destroyed by following."

Nangong Qi was covered in saliva and had no response.

He rinsed his saliva vigorously when he drank water. The cool feeling in his mouth finally made him want to speak with his heart!

"It was too bitter in ancient times!" Nangong Qi muttered, "I didn't dare to talk much without toothpaste! I was afraid that a bad breath would make people faint."

"The skill of career is diligent, and it is wasteful; the action is accomplished by thinking, and it is destroyed by following."

Erlang once again aggravated his voice and repeated this sentence.

Nangong Qi looked up at the sky. At this time, the sun had just risen and looked only seven or eight o'clock. He washed his face again. However, the hair that slid down his cheeks reduced his good mood a little.

"It was really annoying in ancient times!" Everyone grew hair! They couldn't cut it yet! "Forget it, make a little shampoo and wash your hair today!"

"Brother!" Li Erlang finally stopped reciting the books, but shouted heavily.

"What's wrong? Are you hungry?" Nangong Qi was interrupted and looked up at Li Erlang.

The nine-year-old Erlang is about 1.23 meters tall and looks a little thin. His robe is just the same length and his hair is a little scattered, but only by looking closely can you tell it.

"Let's go. Keep eating buns today." Nangong Qi felt that the buns yesterday tasted pretty good. He also wanted to ask the Fourth Master for something.

"Hey..." Li Erlang sighed like a little adult.

After dinner, Nangong Qi quickly walked towards the county government. There are still many things happening today.

First of all, he had to hand over the post. Yesterday, he had already dragged the Fourth Master to ask Liu Sandao about the name of the county master's mansion.

In fact, most county officials are in the county yamen, so Nangong Qi has to go to the county yamen.

By the time I came back, the sun was already rising and the weather was getting slightly hot.

When he returned home, he started his work today.

The charcoal was burned yesterday, and the sulfur and saltpeter only need to be ground into powder.

One nitrate, two sulfonates, three charcoal, this should be a familiar proportion to every Chinese.

However, the actual proportion is one pound of nitrate, two taels of sulfur, and three taels of charcoal!

Do you think this is right? Wrong! One pound in ancient times represents sixteen pounds! So, the ratio is 16:2:3. This is the ratio specially found when Nangong Qi wrote his novel. It impressed him very deeply. Because he always thought it was the ratio of one pound of nitrate, two pounds of sulfur and three pounds of charcoal...

Carefully crushing the three materials into powder, this step took Nangong July 1st.

At noon, he took the initiative to wash rice and started cooking rice. However, he did not pour out the rice water, but stored it.

Li Erlang's memory is not far from having lunch. However, since his parents passed away half a year ago, he has never had lunch again.

This made him miss it slightly.

The lunch dishes were also very rich, with a plate of fried eggs with leeks. However, the egg liquid was collected by Nangong Qi.

"Brother, why did you make it so rich at noon today?" Li Erlang ate the rice in big mouthfuls, while the dishes were small.

"Is that okay?" Nangong Qi looked at the table, a plate of pickles and a plate of leeks and eggs. This is called sumptuousness? "It depends on your hard work in studying, and I will make up for you."

"Oh." Li Erlang was stunned for a moment, and then started to eat in a depressed state.

After lunch, Nangong Qi first made a jar of water and put it under the sun. Then he continued his work.

In the afternoon, Li Erlang read aloud in the living room. Nangong Qi continued to make gunpowder in the concierge.

The weather was surprisingly hot today. In just a while, the water in the water tank outside became milder.

Nangong Qi sweated heavily, but in the end he still didn't finish it all. Seeing that there were about two or three kilograms of gunpowder, he gave up the idea of ​​continuing to crush the stones, poured out a small half and stirred it in the egg white saved at noon.

This is a scene he remembered when he read the novel. It is said that he would make a particle of gunpowder. He happened to have the material in his hand, so he just tried it.

Then he found a broken bowl, poured some water, put some gunpowder, and finally put a piece of cotton rope in it.

This is a fuze that is making gunpowder.

After soaking for half an hour, he took out the fuse in the hottest sun and exposed it to the sun. Then he continued to return to the doorman.

"I'm really suffering!" Nangong Qi wiped his sweat and his face was black. "Is this mission a little too extreme? How can I get in touch with the prince as a civilian? There is no clue at all!"

However, in the simulated world, Feitian does not answer.

Sighing, Nangong Qi continued his work. However, he still had to take some time to make some shampoo. He was going to take a shower later.

Traveling through the ancient three-piece set, ointment, soap, and shampoo. This is the information he wrote in the outline when he wrote ancient novels. Unexpectedly, he actually used it now!

Shampoo is relatively simple.

Just wash rice water, vinegar and flour.

However, he still added some mint. In this weather, in ancient times without air conditioning, mint could relatively replace some effects.

After he finished everything, the sun was already setting in the west. The water in the tank had reached the right level of application.

"Erlang! Come here." Nangong Qi took the lead in greeting his younger brother.

To be honest, on the first day, he was disgusted by Erlang's head oil. He has been enduring it until now.

Due to insufficient light in the room, Li Zhaoan, who ran to the yard, heard his brother calling him, and finally put down the book in his hand. "What's wrong? Brother?"

"Go and prepare some clothes and I'll take a shower for you."

"Ah?" Erlang was stunned. "This is not the New Year or the Festival, why take a bath?"

"You're smelly! Why?" Nangong Qi was speechless, "Go and find some underwear!"

Seeing Erlang still puzzled, Nangong Qi kicked him gently and then walked into his room.

Nangong Qi also found a private Yi. He wanted to wait for Erlang to wash it before washing it himself, not only because he would see the county master tomorrow, but the most important thing was that he smelled too badly.

As a modern person, he can't stand it!

Soon, Erlang walked out, slightly distracted.

However, Nangong Qi didn't care about this, just a little kid who was only nine years old. He quickly took off Erlang's body and then mentioned it in the mixed basin.

"Hey, this is soap. It has not been dried yet, but it can be used. It is rubbed on your body." Nangong Qi handed over the soap like yellow slime.

Erlang was a little surprised after taking it, "Is this what my brother has made these two days? Is it similar to soapcorn?" As a former wealthy family, he used soapcorns when taking a shower.

"Yes!" Nangong Qi did not defend himself. Then a basin of water poured on Erlang's head.

"Puff~ah!" Erlang was caught off guard and stood up from the basin in fear. He covered his wet hair, his eyes filled with anger and fear, "Brother! What are you doing?"

"Mu, Yu, you must wash your hair!" Nangong Qi took a porcelain bottle and poured out the shampoo he had debugged in the afternoon...
Chapter completed!
