Fusu watched Wu Si's movements, and was speechless for a while, secrecy is secrecy, but how to rescue if something happened inside.

Wu # Si saw Fusu's thoughts and said: "Childe, don't worry, this place is just for people to see, and it is also for secrecy, in fact, all the walls, doors and windows have been renovated, and you can come out from the inside at any time, and it is not difficult to enter from the outside." Xue Tu's affairs are like this, and the Mo family is like this, we don't dare to joke with the lives of our apprentices. ”

Fusu nodded, these two remaining high-level ink masters also have some real skills!

"Childe listed gunpowder as a must-master technique, and both of us were involved in it ourselves, but the two of us never participated in it at the same time, just in case."

"You did a good job, safety first, the power of gunpowder is too great, you can't be too careful." Fusu affirmed.

"We conducted experiments based on the records left by Xue Tu back then, and soon discovered the three components of gunpowder, namely charcoal, saltpeter, and sulfur, and the basic ratio is still being studied." The three of them came to a small room that was sealed off alone, and Wu # Si took out another key and opened it gently.

Wu # Si carefully took out a box, put it down gently, opened the box, and said, "Childe, please see, this is the most powerful gunpowder currently in the ratio." ”

Fusu noticed that there was a mark on the box, which read "6:2:2", Fusu looked carefully, and the gunpowder inside was very different from what he had in his old impression of time and space, not silver-gray or black, but slightly yellowish, not powdery, but irregular blocks.

"Where to test? Try a piece and see. Fusu said.

Leng Shi took a bamboo clip from the side, reached into the box and put a piece in a bamboo tube, and then led Fusu away.

The movement of the cold stone made Fusu discover that there was an iron item in the entire laboratory, and everything was either made of wood or bamboo.

Out of the laboratory, everyone walked a long way, until they reached the other side of a small stream in Bowang Garden, the surrounding trees were cut down, only some stones were abruptly placed on the edge of the stream, there were black marks on the top, it seems that it is indeed as the two said, they attach great importance to safety, and it seems that they have carried out many experiments.

The gunpowder was not directly ignited, Leng Shi took out a wooden stick, put it into the bamboo tube, gently scooped it up, checked it from time to time, and after a while, the gunpowder was poured out, which was already a fine powder, and Fusu kept these in his heart one by one.

The gunpowder was laid on the stone, and the cold stone took out a tinder and blew it a few times to ignite the gunpowder.

The gunpowder burned quickly, but it wasn't fast for Fusu. The gunpowder burned with a smaller light and a lot of smoke, but the smell was not strong, and it was not a familiar smell to Fusu, who had no less firecrackers.

However, this effect has shocked Meng An and the others, who saw gunpowder for the first time.

Fusu nodded and said, "It can be seen that you are attentive, and you have done a good job in secrecy and security, but the power of gunpowder should still be improved." ”

It is estimated that the power of this gunpowder cannot even match the gunpowder used to make firecrackers in the old time and space, so don't think that it can be used on the battlefield in the future.

"Let me mention a few points, first, good quality gunpowder should be in powder or granular form, so that it is convenient to use, this piece of gunpowder is not good enough."

"Second, the ratio still needs to be studied, and there is a lot of room for modification."

"Thirdly, there is an impermeable wall in the world, no matter how good the secrecy is, there will be a day when it will be known, so we must be prepared now, the fewer people who know about the process of gunpowder research, the better, and the matter of gunpowder is also kept secret from those who have not participated in it; All gunpowder that has been trial-produced in the past must be kept with samples, proportions, and production methods for future use. ”

"Another point, after all, Bowangyuan is too close to Xianyang, and the place is not big enough, so it is not a good place to test gunpowder, what do you think?"

Bowangyuan just did a gunpowder burning test, and Fusu's ultimate goal is to use gunpowder on the battlefield in the future, what is needed is blasting power, impact force, it is inevitable that if you want to test, there will definitely be a loud noise, a huge earthquake, Bowangyuan is surrounded by royal gardens, too easy to attract the attention of others.

Wu # Si and Leng Shi didn't speak, up to now, there has only been one unknown explosion of gunpowder, that is, when Xue Tu was in charge, as for the specific reason, no one knows, they don't know the power of gunpowder explosion, so they don't know what Fusu means by this, is it to send the ink people to the mountain nest to hide, if so, the ink people still have a bright future?

"Everything is according to Childe's orders." Wu # Si said.

Fu Su thought for a while and said: "In addition to Bowangyuan, only my fiefdom is still possible, but at present, my control of Ruicheng County is not enough, you don't have to worry, you don't have to go all over, you only need to participate in the study of gunpowder in the ink past, the others are still here, and the two gentlemen go to one." What do you think? ”

"Yes." Wu # Si and Leng Shi responded to the order.

"I originally handed over the improvement of iron smelting and brewing to the workshop, but it seems that although there are many workers in the workshop, there is still a big gap between the ability and the ink master, I plan to put these two things in the Bowang Garden, and the ink master will study it, I wonder if the current ability of the ink master can be completed?"

This time, the two of them didn't worry, but they were a lot more at ease, as long as Fusu was willing to do things for the ink man, they would never abandon the ink man suddenly.

"More things, we are very willing, new technology is the ability of the ink man to settle down, but the current power of the ink man is indeed limited...... " Wu # Si said, his face showing embarrassment.

Wu # Si stopped, and Leng Shi said: "If Gongzi can send some more reliable apprentices with sufficient manpower, then there will be no problem." ”

Seeing that Fusu had no intention of objecting, Leng Shi continued: "We heard Zhang Xianjiu say in the Academy Palace that they would graduate from the Academy Palace when they reached the age of sixteen, and the first batch of students in the Academy Palace would graduate at the end of this year, and they had a master-apprentice friendship with us, and their foundations were good......

Leng Shi didn't finish speaking, but the meaning had been clearly expressed, and he wanted someone.

Fusu smiled bitterly, it seems that the effect of the school palace has indeed appeared, at least Wu # Si, Leng Shi and Fei Cheng, who know the details of the students, are very optimistic about the students of the school palace.

Fusu thought about it, this is normal, you must know that at this time, the people who can read and write are aristocrats, and the students in the school palace have knowledge and no background, and they are the talents needed for technical professions such as craftsmen and doctors, and the nobles have no idea of being craftsmen or doctors.
