After the cast iron is cast, it still needs to be polished, and if you hold it in your hand, it can't be too rough, you can't scratch it, and polishing is necessary.

It doesn't take much effort to make the fuse.

The most difficult thing is the firing device, which takes the longest time, but fortunately, there are not many things, and a skilled blacksmith can still make a dozen or so a day.

Therefore, the whole manufacturing process is not difficult, it only takes three or two days to complete. With Zhang Daniu, Duan Dapeng, Wu Jian, and Yang Xiuxiu, there is no need for Wu Ji to do it at all, he is the most relaxed.

The manufacturing process is on the right track, Wu Ji doesn't have to worry about it anymore, and then he will be his hands-off shopkeeper and go to the main bookstore to be the leader.

"Wu Da...... Big brother, you're here! Please come inside! Don't freeze! ”

As soon as he saw Wu Ji's face, Niu Qiqing smiled like a pistachio, and he smiled like a smile, which was extremely cordial, as if Wu Ji was his dearest ancestor. When Wu Ji first came to the main bookstore, his troubled appearance of Wu Ji disappeared completely.

Wu Ji felt something strange, glanced at Niu Qiqing, nodded politely, and quickly came to his seat and sat down.

"Big brother, please have tea!" Yang Yuan was even more thoughtful, stepped forward with a cup of hot tea, and carefully handed it to Wu Ji, with a smile on his face, very kind.

Who would dare to be disrespectful to their immediate superiors? Not to mention, Wu Ji is still a person who is deeply admired by Mrs. Zheng, and the future arithmetic master of Guozijian.

"Lord Wu, you're here!" Huangfu Song is no longer the indifferent appearance of the previous one who has nothing to do with himself, with a smile on his face, he is very kind, holding a cup of tea, and sitting opposite Wu Ji: "Your body is weak, don't be tired, rest when you are tired." Did you have a good rest yesterday? ”

Whether it is ancient or modern, strength is the most important thing. Perhaps, Huangfu Song and they have other thoughts, but this smiling face is a proof of Wu Ji's strength!

"It's okay to worry about work!" Wu Ji drank tea.

"Wu Da...... Big brother, what do you say we are doing today? Is it to settle accounts, or to do something else? Niu Qiqing looked at Wu Ji and asked tentatively.

"Oh? Something else? What does it mean? Wu Ji heard it, and there was something in his words.

"Big brother, you know, we are too slow to calculate the accounts, your bead algorithm is very fast, can you let us know?" Niu Qiqing was stunned for a moment, his face flushed, and finally he said it.

Although he said it very tactfully, Sima Zhao's heart is well known to passers-by!

"Yes! Yes! We have a lot of money here! Yang Yuan hurriedly agreed, with a kind smile on his face, eager to lick Wu Ji's ass.

Wu Ji didn't speak, but looked at Huangfu Song, that means, you are also rushing here, right?

"That's right! I want to learn! Huangfu Song admitted straightforwardly, nodded and said: "If Lord Wu is willing to teach, I will be grateful, and I am willing to give a hundred taels of silver to learn the way of abacus!" ”

One hundred taels of silver, not a small amount, he is really willing to give it. However, if he learns it, he will earn a lot of one hundred taels of silver from teaching others, and he is really shrewd.

However, compared to Niu and Yang, who can only accompany smiling faces and only say good things, it is much more, and Wu Ji's good impression of this Huangfu Song has increased.

"Well, today, let's settle the score!" Wu Ji kept silent about teaching them the way of abacus.

Wu Ji's mind is there, but it is still to the level of a saint. You know, if the abacus method is popular, the social changes in the Song Dynasty will be very great, compared to the popularization of computers, but it will not be too inferior, how can Wu Ji easily teach people?

From this day on, the three of them always changed their ways to get close to Wu Ji, saying good things, patting Wu Ji's sycophants, and wanting to learn the way of abacus from Wu Ji, but Wu Ji had no intention of letting go, although the three of them were anxious, they were helpless.

Under the leadership of Wu Ji, this account was very easy, and the four of them had a good division of labor. Wu Ji is responsible for calculation, and Huangfu Song is responsible for cooperating with Wu Ji, reporting numbers, turning over account books, recording results, and so on.

Niu Yang and the others were unlucky, so they could only do chores, such as serving tea and pouring water, cleaning the ground, and sorting out the account books. From the master of the hall, the nine-rank official of the Song Dynasty has become a miscellaneous servant, not to mention how depressed the two of them are.

However, I can only endure this situation. Who called Wu Ji their top boss, and the two of them didn't open their eyes, and they offended Wu Ji as soon as they came?

It's not that Wu Ji wants to recruit them, but that the two of them voluntarily do these chores in order to forgive their sins.

Time flies, and soon, the period of ten days has passed. In ten days, more than forty thunderbolts had already been made, and Wu Ji took ten of them and sent them to Qiyun Society.

Qi Dabao checked this and looked at that, he was very happy, praised Wu Ji for a while, and paid the rest of the silver.

Before parting, Wu Jite reminded: "Don't disassemble, if something happens, don't blame me for being unpredictable!" ”

"Definitely! Certain! Qi Dabao said this, but in his heart he was thinking, such a good thing, instead of buying it from you, it is better to make it yourself, and not dismantle it.

There will definitely be no fewer people who have this kind of thought, so Wu Ji left a hand to prevent leaks. There are things, only after paying the price of blood, can you learn a lesson, Wu Ji understands Qi Dabao's thoughts, and he doesn't break it, there are times when you cry.

Qi Dabao sent Wu Ji away, rode a tall horse, happily left Guixin City, and galloped away.

After Wu Ji knew the news, he smiled happily, Qi Da kept the money to earn, so he couldn't wait. The more anxious he is, the greater the benefit to Wu Ji, and Wu Ji can receive a large number of orders without going out.

Judging from the information obtained by Wu Ji, Qiyun Society has branches in several nearby cities, and there are many personnel. Among them, there must be no shortage of wealthy people, and after they see the power of thunderbolts, many people will definitely buy them, and this order is not a problem.

Just by virtue of Qi Yunshe, a customer, Wu Ji will make a lot of money. However, Wu Ji was not satisfied, but was thinking about how to sell it to Song Jun.

Selling to Song Jun is an inevitable thing, and it is also Wu Ji's ultimate goal. Selling to the Song army not only makes a lot of money, but also that it is conducive to the strength of the Song Dynasty.

Frankly speaking, Wu Ji did not have a good impression of the Song Dynasty, the weakest dynasty in Chinese history. However, in this era, in the Song Dynasty, there is no escape, if you can make the Song Dynasty stronger, it is to do your part.

If the Song Dynasty can defeat the Liao State, or even destroy the Liao State, it will be even more wonderful, this power, it will be perfect!

Not only made money, but also contributed to the country's fortune, this is a double win, why not?

However, it is very difficult to sell thunderbolts to the army! The difficulty is that there is no breakthrough.

Although the Song Dynasty was weak and its martial arts were weak, the equipment of the Song army was standard, manufactured by the Ordnance Superintendent, and provided by the imperial court. If the army wants to purchase weapons, it will not purchase them from Wu Ji.

Unless, Wu Ji can sway the army! There are such possible surnames, but they are not very large.

Wu Ji could only retreat to the second, get in touch with the army, and have a good relationship with the generals of a certain army, let him purchase thunderbolts, and then slowly grow bigger.

This is entirely feasible, because the Song army had a custom that was different from any other dynasty, and that was to return to Yi.

The so-called return to trade means that the army does business. The army can do a lot of things, as long as it is profitable, it can be done. Such as striking iron, selling weapons, making wine, making food, selling tea......

The most famous is the Fengquan wine drunk by the forbidden army of the Song Dynasty, which has become a famous wine all over the world.

It can be seen from this that to what extent the Song army's return to Yi has reached, and if it is used well, Wu Ji can sell thunderbolt bombs to the Song army through Hui Yi.

Once the thunderbolt enters the army, its prospects are too broad in this war-prone place. Once a war breaks out between the two countries, the thunderbolt will be like a free advertising campaign, and the prospect will be wonderful!
