Qin Feng took Li Ke to the base, and on the square outside the base gate, Liu Hui was practicing military boxing with many children according to the information Qin Feng gave him. Seeing Qin Feng's arrival, Liu Hui led people to salute and shout at Qin Feng.

"See the young master!"

"Get up!" Qin Feng said to everyone.

"Young Master Xie!"

"Liu Hui, the training is good, you go on, I'll go do something first!" Qin Feng said to Liu Hui.

"It's the young master!" Liu Hui returned the salute with a fist at Qin Feng, turned around and shouted, "Continue training, listen to my command!" ”

And Qin Feng took Li Ke towards the inside of the base, and Li Ke, who saw this group of people for the first time, asked Qin Feng, "Fengzi, who are you people?" ”

"I bought it from the slave market two months ago, trained it as a guard, and used it after the opening of the mansion!" Qin Feng said to Li Ke.

Li Ke nodded, indeed, they are all about to reach the age where they can open the mansion, once the mansion is opened, it is indeed inconvenient to have few of their own people around, and he and a few others have always had their own guards, but Qin Feng is considered a lonely person, and after opening the mansion, it is indeed a little inappropriate to use the people of the Yiguo Mansion.

The two went all the way to the craftsman's workshop, where the craftsmen were making the rickshaw that Qin Feng had explained, and when they saw Qin Feng, they hurriedly stopped their work and saluted Qin Feng.

Qin Feng waved his hand and said to everyone: "You continue to be busy, Chen Hao, come here!" Qin Feng shouted at the craftsman who was about thirty years old.

"Young Master!" Chen Hao, who was shouted, ran to Qin Feng's side.

"Have you done all the things I asked you to fix the other day?" Qin Feng asked at Chen Hao.

"Ready, young master!" Chen Hao replied towards Qin Feng.

"Go get it, I'll be waiting for you at the door!" Qin Feng commanded towards Chen Hao.

"It's the young master!" Chen Hao turned around and went to get something.

Qin Feng and Li Ke turned around and walked out of the workshop and walked towards the gate of the base. What Qin Feng asked Chen Hao to take was the nitrate, sulfur powder and charcoal powder made by Chen Hao some time ago, the raw materials for making black powder, because there were several kinds of black powder mixtures searched in the mobile phone, so Qin Feng was not there and did not dare to let Chen Hao experiment with the ratio at will, so he could only let Chen Hao make the raw materials of this formula first.

The two waited at the door for less than two minutes before they saw Chen Hao walking out with a few people, among which Chen Hao and two of them were holding a ceramic jar with a height of 20 centimeters.

Qin Feng saw that people were coming, so he took a few people to the side of the base, and walked about two kilometers before stopping, he didn't want to experiment in this base, in case the dosage was too large and the base was blown up, the gains would outweigh the losses.

When they arrived at the ground, Qin Feng asked a few people to put down the jar, and Qin Feng began to direct Chen Hao to start the experiment with gunpowder. According to the ratio of one to one, the three raw materials are loaded into the paper tube prepared in advance, one end is blocked with soil first, a hole is opened in the paper tube, the lead is inserted through the hole, and then the prepared gunpowder is filled in, compacted with an iron drill, and then sealed with soil, so that it is done. Then Qin Feng continued to direct this Chen Hao to make a few different proportions.

Half an hour later, everything was ready, and the next step was the ignition experiment, which was powerful.

"Chen Hao, run when you light the fire, how fast you can run as many pieces as you can!" Qin Feng explained to Chen Hao, who was about to light the fire, that no one had tried this thing, and Qin Feng was also doing it for the first time, no one knew how powerful it was, so he could only experiment one by one in proportion, but the premise of the experiment was also to ensure the safety of his life, Qin Feng led people to withdraw about 100 meters, leaving only Chen Hao alone, fortunately, the lead they made was long enough, and there was enough time for the person who ignited the fire to run away.

"Order!" Qin Feng shouted at Chen Hao in the distance.

Chen Hao, who was in the distance, heard Qin Feng's order, lit the fuse, and strode towards Qin Feng and the others. When Chen Hao ran back to where Qin Feng and the others were, the earthen explosives that had just been ignited by Chen Hao exploded with a bang, and except for Qin Feng, several people were startled by the sound.

"Qin Feng, what the hell is this?" Li Ke was a little frightened and asked Qin Feng. And the others also looked at Qin Feng with stunned faces.

"The opening of the mountain. I called him dynamite! Qin Feng stood up, said to Li Ke, and walked towards the explosives just now.

Qin Feng led people to the explosion site, there was still some residual smell of gunpowder here, although the ground was full of messes, but the power of this bomb just now was not as high as Qin Feng thought, so he could only continue the experiment again.

Outside the base, everyone heard a loud noise not far away, and Liu Hui thought that something had happened to Qin Feng and the others, so he rushed towards the place where the sound was made with a knife. And the children who followed the training below also rushed to Qin Feng and the others with this Liu Hui.

Qin Feng was just about to conduct the second experiment when he heard the sound of running from the woods behind him. When I looked back, I saw Liu Hui running towards him with a knife, followed by a lot of people.

"Young Master, are you alright?" Liu Hui ran in front of Qin Feng and asked Qin Feng.

"It's okay! What are you? Qin Feng asked at Liu Hui.

"There was a loud noise here just now, I thought something was wrong with you, so I came over to take a look!" Liu Hui said to Qin Feng.

When Qin Feng heard this, he forgot to explain this matter. Looking at the people who came behind Liu Hui, Qin Feng was very moved.

"I'm fine, I'm just doing an experiment, it's okay, let's take someone back!" Qin Feng said to Liu Hui.

"It's the young master!" Liu Hui turned around and left, and brought the people who followed back to the base.

After Liu Hui and the others left, Qin Feng shouted to Chen Hao, who was preparing to light a fire in the distance: "Light the fire!" ”

A moment later, there was another loud bang, the explosives exploded, and Qin Feng once again led people towards the explosion. In this way, after experimenting again and again, the ratio of raw materials of one to one to one to one was finally determined, and then I packed up my things and returned to the base. Qin Feng, who returned to the base, first asked Li Ke to rest somewhere, while Qin Feng brought Chen Hao and the others who followed him to the experiment today to the office.

"Chen Hao, in the future, the gunpowder matter will be handed over to you to be responsible, and you will be the owner of the gunpowder workshop in the future."

"Yes, young master!" Chen Hao bowed down and ordered.

"A few of you go to work first, Chen Hao stays!" Qin Feng said to a few people, except for Chen Hao, the rest of the people bowed and bowed and retreated, leaving only Qin Feng and Chen Hao in the office.

"Chen Hao, the ratio of gunpowder is only known to you and me, this thing is too dangerous, I don't want the third person to know, do you understand what I mean?" Qin Feng said to Chen Hao.

"Young master, don't worry!" Chen Hao solemnly replied to Qin Feng.

"Well, go, I'll leave this matter to you, start making it according to the ratio today, the paper bucket is thinner, and I will go to open the mountain tomorrow!" Qin Feng continued.

"It's the young master!" Chen Hao bowed and retired.
