The amount of gunpowder in the Southern Song Dynasty was not very large, but it also cost more than one million guan a year. This is equivalent to saving the entire Song Dynasty by himself by himself and doubled the performance of gunpowder at the same time. What is this concept!

"Song Chen, don't just talk nonsense to make me happy?" Jia Sidao actually believed in Song Chen's character, but this thing was so good that it didn't look real.

"Zhu Shijie, as the new craftsman of the Gunpowder Equipment Department, tell Jia Xiang about the cost of pelleted gunpowder!" Song Chen introduced Zhu Shijie, which was also a chance to let him leak his face in front of important officials of the court.

Zhu Shijie was one of the four major mathematicians of the Southern Song Dynasty. He was more convincing than Song Chen's words with numbers. He talked about the new technology that Song Chen asked them to use, which increased production efficiency by at least five times, and this reduced unit cost.

Jia Sidao rushed to Song Chen and scared him. What was this guy going to do? He held Song Chen's shoulder with both hands and shook it hard. The old guy was so excited.

He started laughing loudly, and really laughed loudly from the bottom of his heart, "Song Chen, because you seem to be twenty years younger!"

"Song Chen, now let's talk about your 'rain-making machine'?" Wen Tianxiang saw that Song Chen's arms seemed to be falling apart, so he quickly changed the topic.

Although Lao Jia left him aside this time and could not remember his political achievements, he was very happy because from then on, there was another weapon to kill the enemy in the Song army.

"The 'rain making machine' is an exaggeration. It's actually a water tank and a shower. If you use a shower to take a shower, it is a good choice." In order to increase the comfort of his life, Song Chen still used some "privileges" to create it.

From the current perspective, showers have great commercial development prospects. These nobles are very interested in showers. Think about the wealthy officials and officials in the Song Dynasty. Song Chen heard a lot of white silver crawling into his pockets.

As for how to make ice water, I just ignore it. This is a little secret of him. There is not so much saltpeter in the workshop. If you accidentally sprinkle it into the water, it will turn into ice water.

This is not for public use, but for official gun testing, it is just that too much saltpeter is used and too much ice water. I took a bath of ice water in the hot summer, which is not degenerate, Song Chen defended himself in his heart.

"That's what I think. These showers can make life more comfortable. The court can equip soldiers on the front line, which may be useful in improving morale." Song Chen knew how his little bit of fun could deceive the big bosses present. It was just that he wanted the court's big orders.

It would be better to be straightforward to think about it. "This "rainmaking machine" is not as expensive as you think. It is more expensive than the amount, and it is always the same as the old man."

"The nature of a merchant!" Li Tingzhi was very dissatisfied with Song Chen's business, and actually wanted to make money from the sergeant.

"Song Chen, now the imperial court's money is so good that it can be used in half. How can I do this fancy thing?" Wen Tianxiang, as Song Chen's master, had to show his attitude. This guy was simply obsessed with money and had to find a time to teach him well.

This is a secret transaction, and blatant "insider trading" will be restricted in any era, so Song Chen's big order will be still in the womb.

"They are all right, I think you can sell it to me!" Jia Sidao felt that the showerhead was quite new. He pursued a refined life and said that he would become the first to use it. This is the symbol of identity.

"Mr. Pingzhang, this..." Song Chen showed a reluctant expression. If he didn't take the opportunity to make a note of Lao Jia, how could he be worthy of his wealth?

"Is there any difficulty?" Old Jia is also a smart person and does not point it out. If Song Chen didn't know what to say, he wouldn't be polite.

If Song Chen reported too little, Lao Jia would look down on him because he would not use momentum, and the tricks in the middle were very deep.

"Mr. Pingzhang, I spent a full 100% of the time to develop a shower. This is the first one that is not a sale, and it has 'epoch significance'." It takes ten acres of fertile land to buy a bathing game. Do you think I am Yang Guifei? Even a super rich man like Lao Jia will feel so painful. His face is as dark as coal.

"But, if you want it, I think I can only buy this first one and create it by me personally. It is a commemorative shower, fifty taels, and that's really no longer cheap!"

Song Chen said very narcissisticly that everyone has the urge to vomit. Not to mention that he is really right, the first showerhead he created by Song Chen himself really sold at a sky-high price.

"One hundred stakes is only one hundred stakes. Will I still take advantage of you?" Song Chen's statement of fifty stakes is very annoying. Old Jia suffered a small loss, but it was not very comfortable. If Song Chen continued to nag, he would probably be beaten up by him.

Song Chen suddenly remembered that he seemed to have forgotten one important thing. He was so stupid. How could he forget the "crime" of beating Liu Mengyan? Why did he always think about "making money"?

Fortunately, I mentioned this matter immediately, and the backer is the backer.

"Jia Xiang, Song Chen's charge should be offset, right?" Wen Tianxiang had to stand up for his apprentice, otherwise there would be no one.

Even the empress dowager in the palace was paying attention to Song Chen's affairs. Now the least thing the backer wants is to attract more people's attention, so his voice is very low.

After traveling through time, Song Chen still had some benefits. Not only did his physical coordination ability be greatly improved, but his hearing and vision were improved to a certain extent, so he still heard this conversation.

"I know you have already estimated Song Chen's crime very seriously, but it is actually a little more serious than you think." Jia Sidao said seriously, and then he changed his mind.

"Don't worry, since he has made great contributions this time, I will talk about the Empress Dowager."

No matter how bastard this old Jia is, he is still good to Song Chen. He fulfilled his promise and told him that he could go home.

As for the reward, Lao Jia did not mention it at all, and he would never mention the matter of washing away the charge. This was just a "bail". The prosecutor of the Song Dynasty would also initiate a complaint. Song Chen knew that this was a hidden danger. He maliciously thought that it was left to him by Lao Jia on purpose.

Today I actually gained a lot, and I made 2,100 coins out of thin air, which was a huge fortune in the Song Dynasty.

Looking at these copper coins, Song Chen felt that he was very "noble". For the sake of "I'm the Song Dynasty", I had to accumulate wealth until astronomical numbers every day.

Just as he returned to the military weapon prison room, Song Chen was almost scared to death when he opened the door. A man sitting cross-legged on the bed, Shang Yidao looked at him with his eyes that looked like Tongling.
