After three days of dust, Zhang Mu and his party were rushing. When they rushed into the gate of Yongkang, Zhang Mu saw the familiar streets, bathed in the sunset, quiet and comfortable.

It made Zhang Mu feel that all this was a little dreamy.

When I left Yongkang, I just wanted to take the imperial examination. But I didn’t expect that I would have experienced so much in just two months.

They walked along the way, so they didn't worry that Elf would catch up with them.

Zhang Mu immediately took his subordinates toward his house.

Several servants at the gate were all playing chess and chatting together. Seeing Zhang Mu's shadow, someone immediately went in to report it.

In a moment, the old housekeeper took the people at home and waited at the door. When Zhang Mu had just arrived outside the gate, the old barely hurriedly ordered the servant to greet him.

Zhang Mu looked up at his mansion and said to himself: "I'm finally back home."

"Young Master, you are back. These days, you have not heard from you everywhere. I said that you had made a mistake some time ago, and everyone in the house was frightened..."

Listening to Zhang Wenguang's nagging, Zhang Mu suddenly felt very friendly for some reason.

"Carry out some guest rooms for them, these are all my colleagues." Zhang Mu smiled.

Zhang Wenguang hurried to go to work hard, and after Zhang Mu settled everyone, he headed straight to the backyard.

Now Ting Hexuan in the backyard has been released into a separate courtyard, and Zhang Mu asked Song Wen to make soap base in it.

I was originally going to use what I learned to make a big move, but I didn’t expect that when I entered the officialdom, everything seemed to be out of control.

After not seeing each other for a few months, the pine wind is still the same, and there has not been much change.

When he saw Zhang Mu, he hurriedly greeted Zhang Mu.

Zhang Mu ordered him to take some soap and hurried back to his room.

After closing the door, the old housekeeper came hurriedly with the account book. When he saw Zhang Mu, he hurriedly said, "Young Master, you are not at home for this period, and your business is very prosperous. But last month, a yamen messenger came in the county government office and sealed off all the business at home."

Zhang Mu knew that it must be because he offended Wang Ming, so he waved his hand and smiled, "I will talk about these things later. I asked you to make Yunnan Diatomaceous Earth. Have you got it?"

Zhang Wenguang nodded quickly and said, "I have been here a long time ago and have been kept in the warehouse."

"Get some for me quickly, I'll be of great use." Zhang Mu smiled.

The old housekeeper hurried to get it, and Zhang Mu grabbed him and said, "Wait, it may not be peaceful these days. Please make everyone in the yard be careful."

The old butler was stunned. He understood what he meant and hurried out.

After a while, the old housekeeper sent someone to send diatomaceous earth, and Zhang Mu sat next to the table and began to complete his bomb journey.

Glycerin can be extracted from the scraps left by making soap.

The sulfuric acid extracted from blue alum was soaked in saltpeter. It was nitric acid.

Soaking nitric acid in glycerin is the nitric acid 1 glycolic acid 1 oil invented by Nobel back then.

Because nitroglycerin is very unstable and will explode after shaking, it is basically impossible to use.

However, with diatomaceous earth, the situation is very different.

Nitroglycerin soaked in diatomaceous earth is the famous yellow gunpowder - Dana explosive.

Zhang Mu then began to purify glycerin. However, the process was limited, so it would be fine as long as it could be used.

After getting glycerin, Zhang Mu brought these things to a warehouse in the backyard.

After asking the people to move all the things in the warehouse, Zhang Mu ordered people to block the backyard, and then wrapped them in a few layers of quilts before entering the warehouse.

The most terrifying thing about the whole process is that you only make nitric acid 1 1 glycolic 1 oil. Although this thing is very powerful, it is really not very stable.

Nobel's younger brother was killed by this thing, so he couldn't joke about it.

Zhang Mu took a deep breath and carefully poured the glycerin into a ceramic basin, then raised the nitric acid and wiped the cold sweat from his forehead.

I thought it was still unreliable, so I prepared a long bamboo pole and hung the bottle on it.

Standing at the gate, then slowly poured the nitric acid from the bottle into glycerin bit by bit.

Glycerol quickly starts to react under the chemical action of nitric acid.

Zhang Mu waited carefully at the door until the morning of the next day, and saw from a distance that the glycerin in the ceramic basin was completely dissolved.

The most dangerous step is finally completed.

Zhang Mu leaned over carefully, then sprinkled the diatomaceous earth in his hand into the ceramic basin bit by bit.

I held my breath and waited for a long time before I carefully retreated.

Then he ordered people to guard the door and wait for the diatomaceous earth and nitroglycerin to react.

After not sleeping all night, and having been running around for several days, Zhang Mu was also sleepy and returned to his room and fell asleep in a drowsy way.

I don’t know when, but when I felt itchy on my face, I opened my eyes tiredly. The first thing that caught his eyes was a cute pretty face.

The long hair was combed into two whips, and the hair behind it was shaped into a collar and tied into a small bun, which was playful and cute.

A pair of blue eyes, as bright as sapphire, pure and flawless as the lake water in late autumn, makes people intoxicated.

On his round little face, two dimples will appear with a smile, and both white teeth will be like weaving shells.

The little girl looked at Zhang Mu in a daze. When she saw Zhang Mu wake up, she shouted loudly: "Muguoguo, it's already afternoon, she's sleeping like a pig. She can't even wake up even when she shouts."

Zhang Mu smiled and said, "Jiao'er, why are you here?"

"Stingy guy, I don't know if I come back. If my father hadn't told me, I wouldn't know." Qiaoer said angrily.

"Sir, are you here?" Zhang Mu quickly turned over and looked out the window. It wasn't it, it was already afternoon.

Qiaoer took the shoes for Zhang Mu obediently and put them on the ground and said, "Put it on quickly. What good things have you brought to Qiaoer when you come back this time?"

Zhang Mu smiled and said, "Show it to you later. I'll go see you first."

After saying that, Zhang Mu put on his clothes, cleaned up for a while, and followed Qiaoer toward the study.

After pushing open the study door, Wang Hongtai was focusing on an ancient book. He hadn't seen it for several months, but he was much more energetic than before.

Zhang Mu saluted him first, then smiled and said, "When did sir come? Why didn't I wake me up?"

"I heard from someone this morning that more than ten batches of horses arrived at your mansion yesterday. I was worried that something might happen in your mansion, so I came to take a look first. Only then did I know that you were back." Wang Hongtai smiled.

"I'm going to go to your house to see you. How is the master's wife in good health?" Zhang Mu asked with a smile.

"Everything is fine." When Wang Hongtai said this, he smiled awkwardly and said, "Qiao'er, you go out first. I have something to say to Mu Zhi."

Qiao'er stuck with Zhang Mu, waiting for the gift, where was she willing to leave? But seeing her father's face turned pale, she reluctantly made a face and ran out happily.

Seeing Wang Hongtai's expression, Zhang Mu asked curiously: "Sir, is there something to ask me?"
