After working all day, Song Chen felt soreness in his back.

Although he was lazy in his previous life, he was not so tired that he couldn't straighten his waist when doing this little work. This is because he was not in good health, which also reminded him that he must strengthen his physical exercise.

As a senior otaku in the 21st century, he did not think he knew more about physical exercise than people of this era.

However, physical exercise must be put on the agenda. If you can learn some kung fu and increase your martial arts value, it is best.

This plan doesn’t work today. I want to spend two days now. I don’t have time to exercise now. Let’s go ahead!

Song Chen walked slowly and found that this place could be described as three steps and one stairs and one whistle in five steps. This place has become a forbidden area, and they do not want to reveal any news to the outside world.

Song Chen thought that in fact, it was unnecessary to do this. Such a high alert force would be impossible not to attract others' attention. However, if there was no alert force, it would be even more unreasonable.

Of course, he has no better idea yet, so he can only complain.

The next day, Song Chen had to continue to work hard like a little bee. When he went there, he saw that these guys who were not convinced had already started to produce step by step. They had completely accepted the new process, which was a kind of comfort.

It has to be said that power is a good thing. If he did not use the power in his hands and gave them a warning, these stubborn and proud craftsmen would definitely still make gunpowder in their old ways.

There is still a little regret. The power in his hands was granted, not from him. Song Chen is a smart person and understands the differences.

During these days, he felt that the young man of his age was constantly creating surprises for him.

He is really sensitive to numbers. In addition to being a little arrogant, he is also honest and reliable.

Song Chen is a special candidate, who will be given to the Firearms Department to manage, and this person must be reliable and talented.

The formula can be handed over to the master of the school, this is an excellent candidate.

This is a condition that he had already negotiated with Jia Sidao. Song Chen still had a great time waiting for him. He could not stay in this firearm department all his life.

If I don’t want to take over, I have to find someone to take over, right? So finding a craftsman for the Firearms Department has become a pressing task for Song Chen.

If he fails to complete the task, he will be trapped here all the time.

In fact, there is only one core point when so many measures are taken, which is to prevent the best ratio of gunpowder from being leaked under the premise of mass production.

Of course, neither Lao Jia nor him think that this formula can never be leaked, and various accidental factors cannot be prevented.

But at least to this extent, before the Song Dynasty won this national defense battle, the formula must be firmly in the hands of the Song people. This is the bottom line.

Song Chen felt that what he gave to the young man was not a gunpowder formula that rewrites the history of world wars, but a huge shackle. Once he agreed, it was equivalent to putting it on a shackle.

This may take ten or twenty years. I really don’t dare to think about it after a long time. Even Song Chen will feel a little guilty.

"What's your name?" Song Chen asked softly. In fact, he was still very turbulent in his heart, and doing so was a bit immoral.

Make a good deal of it. In many cases, to achieve great things, you must blur the moral boundaries and do something less brilliant.

However, Song Chen drew a line for himself, a line he would never cross. He would not be a traitor and not do anything that would harm the interests of the Chinese nation.

He told himself that he would be the devil who would never be restored after crossing that line.

Seeing the simple look of the academic master, he decided not to act according to the route set by Lao Jia, but to reveal the situation and let him make his own choice.

If he doesn't want to do so, of course Song Chen really hopes that he will agree.

"Zhu Shijie!" The young man was very tall and loudly reported his name.

This name is a bit familiar. I searched for the huge database in his mind. After traveling through time, it was formed by the memory that expanded n times. It can completely act as a small electronic library.

The director Song Chen can read a large book efficiently in 01 seconds.

I simply searched, my god, isn’t this person one of the four major mathematicians of the Southern Song Dynasty?

It’s a bit embarrassing. Could it be that this genius figure is tied to the Firearms and Workers Department and that he will be the director of a gunpowder factory for his whole life?

What's wrong? At least I can arm his mind with my mathematical knowledge that has surpassed him for ten centuries, and perhaps he will achieve more brilliant achievements in the field of mathematics.

"I have a very difficult thing to do now. I want to find you, but I don't know if you dare?" Zhu Shijie's appearance is at most 20 years old. He is at the age of a young man. Song Chen was very unkind and provoked.

"Why don't you dare?" Zhu Shijie was in his prime after all, and Song Chen, a not-so-wise provocation method (extra: it's actually very low-level), aroused his competitive spirit.

After all, the big talk is ahead and I am not embarrassed to refuse afterwards. People need shame.

"My gunpowder formula is the best ratio. The rise and fall of the firearm is maintained on this. Don't rush to express contempt. You will witness its power with your own eyes later." Song Chen was not surprised at all with his disdain for the academic masters. The purity of saltpeter has improved, but they did not see the power of particulate gunpowder. Seeing is real and hearing is weak.

He patted Zhu Shijie on the shoulder and said to him in an elder's tone. In addition, this was an unconscious expression from Song Chen. After all, he was a time traveler and his psychological age was over thirty.

"I want to hand it over to someone who can trust and prepare to hand it over to you. Once accepted, your treatment will be improved accordingly, and there will be fertile land in the house." Song Chen is like a weird uncle who deceives the child with a lollipop.

"I haven't seen whether your formula works yet. Any brother from our Firearms Division you said would dare to do this, otherwise we wouldn't have been selected!" Zhu Shijie felt that Song Chen underestimated him, and even more underestimated their Firearms Division's brothers.

"And once you take on this position, it means that you are the only person who knows the ratio besides me, so it is equivalent to being confined to this place. This period may be a bit long, five years, ten years, and a lifetime. Of course, we can build a very beautiful attic for you here and find a very beautiful one for you..." Song Chen basically mentioned the disadvantages in the front, but the benefits behind are very specific.

But he was not degenerate yet, and he didn't remind Zhu Shijie that once he took on this life, he might be trapped in that besieged city for the rest of his life.
