Liu Yuan's face turned blue and white. Tang Hongying took advantage of Feng'er's illness and wanted his life. If she hadn't been alive, she would have been unable to hold on: "She is really bullying, I can't even agree.

Let you leave the mansion and spend your whole life to make the reputation of the eldest son.”

"She can even take such a harsh action!"

Qin Feng held his forehead: "My aunt made the wrong order. She first poisoned her first, and then the exchange was made for her son to move the yard so that she would not blow the wind every day, and then the son would learn medicine to save himself."

Liu Yuan smiled awkwardly and said, "My aunt has contacted your uncle and solved the misunderstanding. It turns out that the message was not delivered in place. Both parties gave up on themselves because the other party gave up on themselves. In this way, the aunt can have a place to go."

This is Qin Feng's purpose. He said immediately: "My aunt gives me a correspondence address, and I will also write a letter to recognize my uncle."

Liu Yuan couldn't ask for it, so he brought the Liu family's place to settle in Jiangbei. Originally, the business competition in Suicheng was fierce. In addition, the Liu family suffered a lot because the Tang family suffered a lot, so they moved to Jiangbei to work, and instead planned many industries in Jiangbei.

Qin Feng wanted to contact the Liu family, firstly to give Liu Yuan a place to go, secondly, when he completely evacuated in the future, he should not leave his relatives or friends to suffer. Although the Liu family has not contacted them for many years, he really cannot be fully aware of it.

When you retreat, wouldn’t you implicate them?

There was Liu Yuan's relative who was richer than water. He could not leave and ignored everything. He kept in touch now and was to facilitate his actions in the future. He did not have the Liu family in his memory. In fact, it was exaggerated to the relationship.

, mainly for morality.

Qin Feng checked the address and looked at Liu Yuan's uneasy feeling. He knew that what he said had caused an impact on her. He reminded him: "It's good that my aunt knows it. After many years, there was no evidence or physical evidence at the beginning. I wanted to settle the score later.

Disaster."

"I can save you this, but since this account is placed here, I have to count it." Liu Yuan seemed to think of something and raised his lips gently: "Who said that this liquidation must be the name of your being filled with medicine, if not

, I'll find one."

Now she is in charge of the family and has many opportunities.

Qin Feng gave Liu Yuan a thumbs up in his heart, and it was done. He waited for the show behind him and then he was done.

Liu Yuan has now contacted her parents' home and is in a good mood. Unlike before, she always felt like a rootless duckweed. People have something to rely on. This mentality is naturally different. Qin Feng saw Liu Yuan, who was much more indifferent.

Seeing Qin Feng, Liu Yuan thought of another thing: "Qi'er came back a few days ago, and this child was surprised. He mentioned Yuan's tears in front of me, but when he arrived at his father's place, he only

Without mentioning the words, this child can become a great man in the future.”

This must be someone to give me some advice. Lou Mingyue not only teaches him how to do things, but also takes him to do things and knows what to do in front of whom.

It would be good that the master and apprentice had returned from the southeast, and Qin Feng's heart was also lost. Yuan's family led his people to work on the brutal cliff, so he should also take good care of Qin Qi: "Qi'er has super hands-on ability, if she can really succeed in the future

There are also master-level figures.”

The mother and son have not seen each other for a long time, and now they have been chatting endlessly. If I hadn't remembered that there was something important to do, Qin risked to respond to Liu Yuan's request to keep him for dinner. He would have been waiting for him after leaving the Taifu Mansion.

Long Qi crawled out: "The boss, you're ready."

After getting on the carriage, the carriage did not drive to the princess's mansion, but went to his most secret residence where He Lishu was stored. After entering, he went to pick up He Lishu first. When he opened the words on it, he couldn't help but smile.

, tore it and throw it away.

As the saying goes, man’s calculation is not as good as God’s calculations. No matter how good the plan is, it depends on changes. Who would have expected that the separation will turn into a loss of a wife?

He and Long Qi brought the prepared things into the secret room, and then opened Lu Qi's booklet. The pavilion master had long developed the formula for gunpowder, which is worthy of being a geology, not only having a counterweight ratio, but also chemistry.

The performance is also prepared.

What can be made in this dynasty is black gunpowder, and the main formula is carbon-containing substances such as saltpeter, sulfur and charcoal.

The final combustion aid is completed by the oxidant produced by saltpeter. The most important thing is the combination ratio. Lu Qi didn't know how many times he tried it to determine the final ratio, and the most important saltpeter accounted for 60%.

Looking at the percentage number above, Qin Feng felt emotion. He was also a person who came through. He had found so many minerals, so why did he mess it up? He was grabbed by Zhenbeihou and was seriously ill.

I want to build a paradise and be dragged down by my disciples who want to gain fame and have to work hard to support my disciples. This is wrong.

Since you have made efforts, you should be rewarded. How can you support those people in vain?

Qin Feng, who has prescriptions and has the foundation for experiments in the past, has very strong hands-on ability, has configured it without any effort, but Long Qi said that this is extremely difficult to get.

There was a group of people in the city who went to find the old city walls, and the soil on the foundation of the old walls could only be refined into nitrogen. The price was high, and the quantity was not large.

When Qin Feng heard this, does this mean that mass production is troublesome?

He hurriedly picked up the booklet to read it, and it really mentioned the origin of the nitrogen. The best way is to be a saltpeter mine. This saltpeter mine is just in the southwest. Qin Feng felt a little moved, and there was a geological map.

In the southwest, this problem is solved.

Saltpeter has been recorded as stone removal in history, and its chemical composition is actually potassium nitrate. Saltpeter in nature is composed of nitrogen-containing organic substances in soil decomposed under the action of bacteria, oxidized into nitric acid and combined with potassium in the soil.

In addition to saltpeter mines, after autumn, it will cover the corners of walls or ground in the shape of a salt flower, which people call ground frost.

The people in Dongyue have nitrogens, and nitrogens are specialists in taking nitrogen. They look for ground frost everywhere and put them in buckets, soak them in water and then filter them, and take filtrate to boil and dry them. What they get is saltpeter.

There was no mine in Sui City, so Long Qi found many smelting people to buy these, and spent a lot of money.

It seems that to stock up on firearms, you need to open a saltpeter mine first. Qin Feng is glad that the saltpeter mine is in the southwest, which saves a lot of trouble. Qin Feng breathed a sigh of relief and signaled Long Qi to try it. Long Qi took the fire and was a little hesitant.

: "What will happen to this medicine?"

"Explosion." Qin Feng said a word that Long Qi had never heard before. Seeing that he was puzzled, he explained: "You can order it and try it."

Long Qi is a brave man. He really took the fire lead and Qin Feng controlled the amount. After igniting it, he blew the ground. Long Qi almost couldn't control his mouth and shouted out like a woman. He saw the fire brazier.

They were all exploded, and his expression also broke.

"This is the power of gunpowder. This is just an ordinary dosage. If it is increased, it will blow people to death. No matter how powerful the building is, it can collapse." Qin Feng said: "Long Qi, your Pavilion Master has already figured it out.

Such a good weapon.”
