It is not spring to make ice with saltpeter, but it is beneficial to make ice in the first place, but in fact it is just to make fresh things. There is not much benefit after summer. Unless the gunpowder formula is produced, it will bring huge profits. The old Ganlong treats himself kindly and regards himself as a son and nephew. This benefit is given to the Gan family, which can be regarded as a reward for the gift of the old Ganlong. Will the Gan family have no expression? Besides, the Bai family is both Wenhua supermarket and paper-made. A book called "The Jungle of the Young School" is said to have been spread to Yue Kingdom, where wars are frequent. How many people have jealous? It is also necessary to let the Gan family share the limelight so that they can let go of the other important things in the promotion plan.

So Bai Dong ignored Du Zhi, pulled Gan Sheng to his side and whispered a few times, and then took out the pre-prepared silk book for him, which showed how to make ice with saltpeter. Gan Sheng looked at it a few times, almost burst into tears, and pulled Bai Dong to ask him to sign the contract.

In the early Warring States period, countries successively reformed the law. The emergence of emerging landlords and free farmers stimulated commercial exchanges. When encountering large-scale transactions, it became an unwritten rule for both parties to engrave the recognition of the contract in the book of the book. Unfortunately, there was no "International Private Law" similar to later generations, and even the "Marine Law" of the Roman Empire era. Once a dispute arises, it would be fine if both parties to the contract are in the same country. If they belong to different countries, the contract will become evidence to condemn the other party on the moral level, but it has no legal practical significance. However, the Gan family and the Bai family belong to Lao Qin, so this thing is still useful.

Bai Dong looked at the contract written on the silk book and smiled unconsciously: "Brother Gan Shi, with the friendship between you and me, it seems that there is no need to distribute benefits like this? I just provided a small way to turn ice in summer to tell you where the saltpeter is; the Gan family is going to travel to Longdong to transport saltpeter. They also have to operate it in Liyang. The energy it has been filled with is much greater than mine. In this way, I will share 60% of the profit. I am really uneasy?"

"Brother Bai, what's wrong with this? If it were me, I'll give you 70%!"

Du Zhi looked at Gan Sheng angrily. In the face of business interests, he was famous for not recognizing his relatives, not to mention a mere son of the Gan family, or the old Gan Long here. He would first respectfully worship his mentor, and then negotiate with the Gan family as a businessman. People who study mathematics have always been rational and can't act emotionally. In his opinion, Bai Dong is too emotional. It is good to speak of feelings. It's just like Du Zhi. Everyone is a partner, and there is no need to be such a slippery man for Gan Sheng. Don't look at this guy as fat as a pig. In fact, he is more skilled than a monkey.

"The Gan family also paid 70%!" Gan Sheng stared at Du Zhi, so angry that his body was trembling with fat. This guy was simply a fool of his master and a master, and he was not a son!

"Okay, Brother Gan, I only have 50% of the profit. In addition, there are many wonderful uses for growing ice in summer. I will pass it on to the Gan family one by one, but there is one condition. In the future, the Gan family will transport saltpeter from Longdong, no matter how much, it will be half of the Bai family. How about it?"

"It should be!"

Gan Sheng really wanted to laugh out loud. He wanted to give Bai Dong 60% of the profit, but he took a fancy to Bai Dong's follow-up methods. Now he only needs 50% of the time, and it's just that he wants some saltpeter. Brother Bai said, "The Wu Ju Wu" has nothing else in the valley, but there is too much saltpeter. It can't be finished after ten or eight years. Now Yiqiu has become a vassal state of the old Qin Dynasty. It's just a matter of one sentence for the Gan family to buy this valley. Are you afraid that the old King will not agree?

"Nie Zhu has been yelling these days, saying that the battle in Longdong was too easy and his murder was useless. When Brother Gan left, he asked him to help escort the car. The battle was clear, and there was still chaos in Longdong. Although the Gan family was protected by hired Rangers, many masters were also good."

These saltpeters are very important and must not be unexpected; in this era, there are no shortages of sulfur and huang in pharmacies. They are not only used as medicine, but also a must-use alchemy materials for those alchemy priests who are not afraid of death. Charcoal is even easier to make. Now with saltpeter, black gunpowder can be produced in minutes.

Bai Dong never thought of giving the black gunpowder formula to Lao Qin, at least not now. Lao Qin has a weak economic foundation and is not the time to dominate the world. If Ying Lian or Ying Quliang is addicted to this thing and wants to start a war with the power of gunpowder, it would be like a disaster for Lao Qin.

Although black gunpowder is powerful, even in the Song Dynasty, which widely used this object, it could suppress the alien races using cold weapons. Should Kaifeng be thrown or lost, and whether the Northern Song Dynasty was destroyed or destroyed. Too superstitious about modern technology is the biggest misunderstanding; unless he has the ability to launch an industrial revolution and create modern factories and military factories in Lao Qin, but this may be possible? Not to mention Lao Qin, even the most powerful Wei State at present does not have such economic and material conditions. Even the old scientists of the Chinese Academy of Sciences come together, they will never be able to do it without a hundred years.

However, it is still possible to quietly use some black gunpowder, explosive packs, landmines, etc. to protect Baijiazhuang. As long as this technology is not published to the public, everything can be pushed to mysterious phenomena.

I remember that later generations Han Fei once blew Liezi's big blow, saying that he could fly with the wind and hide in the clouds and mist, and he could almost travel to the North Sea and stay in the South Mountains in the evening. It can be seen that people in this era were romantic, and even legal scholars like Han Fei were no exception. He was a member of Qingxi, and Guiguzi might not be much worse than Liezi. If you say that the explosive pack is a thunder in the palm of your hand, who can refute it?

When Bai Dong thought of the cheap master, he was extremely curious. Guiguzi must be an intelligence expert, otherwise he would not be in Guigu, Qingxi, but could know his every move; and he was probably very idle, otherwise he would not have trained to give it to him. What exactly did this old man want to do? He knew that he was a tiger skin and was cheating everywhere under his name, but he didn't come to expose himself. The old guy was very thoughtful enough? He actually couldn't guess.

Gan Sheng was extremely excited and gave Bai Dong a hug. This was considered a violation of etiquette and a bad habit learned from Yiqu people. After hugging Bai Dong and left, he ignored Du Zhi. Du Zhi looked at his back, his eyes looked a little like a rabbit: "Brother Bai, saltpeter has great benefits, if it is in my hands..."

"Okay, I know you are arithmetic, and you will go crazy when you think of numbers. Think about it, what is the first pig that was killed like? It's the fattest one! So you can't be too Hu Xueyan..."

Du Zhi was stunned: "Who is Hu Xueyan?"

"Uh, you don't know this after saying it. Think about it, what would you think if I wanted to eat alone that day? If you and I were alone, what would you think of the various aristocratic families in Lao Qin? There are many ways to make money. If you have to occupy all your methods and let others live? Even God will punish you at that time! Uncle Gan is good to me, what would be the harm of letting the Gan family monopolize the future Lao Qin Bing City? If you understand, follow me if you understand..."

"Go? Where to go?"

"Let you see something. With it, our papermaking workshop can make better paper. At present, many nobles and scholars use paper when they are cheap, but they still don't agree with the silk paper with low ink ability. We want to make a new paper that will make them crazy just by seeing this kind of paper. You have to remember Brother Du, as today, as the hundreds of schools of thought contend, everything in the world should be based on literature, so the money of scholars is the best to make. They are the most lovely guests, and they don't know how to bargain, nor have the shame to bargain. If these people don't make money, I can't forgive myself."

Du Zhi was stunned at first, then laughed: "Brother Bai, it turns out that you are more greedy than me."

"Nonsense, I'm going to get married when I go back. I'm going to take care of my family. If I don't make more money, would I have to let my wife and children drink the northwest wind? Brother Du, have you ever thought about giving me a big red envelope?"

Du Zhi was stunned when he heard this. After all, you are Zuo Genggao Jue, who is two levels higher than Zuo Shuchang, so you won’t be more reserved. You can please others when you speak. How can you be more scheming than me? But the more Bai Dong is like this, the more he feels kind. He feels that he is in a terrible smell with Brother Bai, and he is a perfect partner. The mountains and rivers are flowing, but unfortunately there is no piano in his hand, otherwise he would have to compose a "Businessman Song" to match the Bai brothers Gong Yu. Wouldn’t it be pleasant? (To be continued...)
