It is convenient to have power and subordinates. Liu Feng doesn’t need to take action by himself. He just needs to talk and give a simple order. The materials for making black gunpowder will be found soon.

Charcoal is simple and saltpeter is easy to find. There are particularly many corners near pigpens, stables, and pits. Sulfur may not be easy to find in other places, but it is not a rare thing in Tangyuan Mansion. There are coal mines everywhere here and there are also natural sulfur mines.

While looking for these materials, Jinyiwei found a natural sulfur mine near a Taoist temple outside Jingxian County, and there was also a natural hot spring on the mountain.

"Master, these refined sulfur powders were all made from that Taoist temple. Those Taoists like to use this thing to refine alchemy."

Xu Tu smiled at most of the bag of sulfur powder on the ground.

"Well, have you paid?"

"I gave it, but they dared not accept it. They said that this was filial piety to the Lord, so I won't force them."

"Not bad. I asked someone to help me build a villa near the hot springs on the mountain. It would be nice to have time to soak in the hot springs."

"Yes, my subordinates will make arrangements right away."

After finding all the materials, the next step was to configure black gunpowder. Since Liu Feng didn't know the ratio, he had to ask people to keep trying. Anyway, there were enough people, and there were more than 65,000 people locked up in the prison camp. If you find more people, each person would try a different proportion.

After arranging the people and configuring gunpowder, Liu Feng came to the logistics camp's base and gathered all the blacksmiths over.

"Lord, this old blacksmith is the best blacksmith in our logistics camp."

Zhao Ming, the manager of the logistics camp, pointed to an old man and introduced.

"May I have your name?"

Liu Feng looked at the old man. He was not tall, but his muscles were very strong and his finger bones were particularly thick.

The old man hurriedly replied: "The little old man, his surname is Liu, lord can call me Blacksmith Liu."

"Can such a round solid iron ball be made?"

Liu Feng took out a drawing he drew and handed it over.

"It can be done, but it takes some time."

"It's fine to do it. Make a few of them as soon as possible according to the size above. I have urgent needs."

"Yes, yes, I will make it as soon as possible."

Liu Blacksmith nodded and said, looking very nervous. If you look closely, it was not only him, but other blacksmiths. After all, in their eyes, the "beautiful" young man in front of him was the leader of the army, a high-ranking figure. In anger, he could make thousands of people fall to the ground.

After Liu Feng left, two figures emerged from the corner not far away.

"Sister Zhou Qing, that's your leader? I look quite young last year."

Qin Feiyan's eyes were filled with a strong curiosity.

“Yes.”

Zhou Qing was a little confused. Although she had become a chore maid around Liu Feng for a long time, she had always been in other yards and rarely had the chance to see Liu Feng in private. Even if she met, she still watched him leave by a group of people from afar, and had never looked at his front carefully.

"I originally thought it was a one-eyed man with a fat face. He was so handsome, no wonder he could defeat the reinforcements of the court."

Um?

Zhou Qing was a little confused when he heard this. Is this war related to whether he looks handsome or not?

"Sister Zhou Qing, this is my owe to you. Today my brother sent someone to pick me up home."

Qin Feiyan was in a good mood and took out a ingot of silver and stuffed it into Zhou Qing's hand.

“There are too many!”

Seeing such a large ingot of silver, Zhou Qing couldn't help but tremble.

"It's okay, thanks to your care during this period, the extra gift I give you will be the thank you."

Qin Feiyan waved her hand indifferently. Just ten taels of silver were not enough for her meal at Zuixianlou.

"Why are you so embarrassed? You're so polite."

Zhou Qing said while hiding the silver in his arms. His originally close-fitting clothes suddenly bulged a small bag, "I remember to come and play often in the future, I will teach you how to shoot arrows."

"It's great, so don't wait for the future, let's start now."

Qin Feiyan was a little surprised. She had seen Zhou Qing's archery technique. It was really a hundred steps to penetrate the Yang, and she had been coveting it from wherever she pointed.

Unfortunately, I wanted her to teach her archery skills before, but I never succeeded. Why did it suddenly become a big deal today? It made her feel a little unreal?

"Now? Didn't you say someone from home picked you up?"

"Hey, I've been here for so long, and it's not bad for these few days. Let's leave quickly."

Qin Feiyan pulled Zhou Qing and walked out.

For the sake of money, Zhou Qing had to reluctantly agree.

······

Three days later, with the news of good news coming back, almost all Tang Yuan Mansion had fallen into Liu Feng's hands. Because of the experience, Pang Bin did not make any mistakes when arranging people to take over these county towns, everything was planned.

"Master, the shells and gunpowder have been made out, so you can test the cannon."

At noon that day, Xu Tu ran over to report to Liu Feng with excitement.

As an Jinyiwei, I naturally knew the cannons and even knew how to shoot cannons. When he saw the five red cannons at first, he fell in love with these five big guys. In the past few days, he has been watching the progress of gunpowder and shells almost every day, and he is more anxious than anyone else.

"Okay! Let's go and test the gun now!"

Liu Feng was also a little impatient.

Five red cannons were placed in the camp outside the city and were not transported into the city. This time, Liu Feng not only called Pang Bin, Zhou Wencai, Yang Rong and others over, but even Qin Feiyu was invited.

Qin Feiyu attached great importance to this invitation. Although he didn't know what the content was, he had to make his attitude. After all, he was on the other person's territory now, so he set out in advance and came to the camp outside the city.

This was his third time here. The first two times were at night. The sky was too dark, and he had no time to take a look. Now when he came in, he found that the soldiers here were all tall and burly, and unnaturally showed a kind of unruly and evil spirit, which made people feel cold. These black-armored soldiers knew that they were more elite than those in the city at a glance.

"This kind of soldier is definitely not composed of hungry people. It seems that behind Liu Feng, there is indeed a great force to support him. I don't know if it is the Northern Wei or the Western Qi. He can command such an elite army at such a young age. His identity is probably not low. He is likely to be a prince of a country. If this is the case, it is really a rare thing. Our Qin family must grasp it well."

Qin Feiyu began to constantly repair his brain.

"Brother? Why are you here?"
