"I think you should think about it again. Once you become an official, you won't delay your cultivation of flowers and plants!" Princess Chengyang, who returned home, still did not give up and advised again.

"Thank you for your kindness, but I feel that I am not ready yet!" Zhang Zong refused helplessly.

"that……"

At this moment, Xue Shao next to him seemed to be unable to hold it in his arms, but as soon as he spoke, Princess Chengyang glared at him. If it were placed before, Xue Shao would definitely be so scared that he would not dare to speak. However, this time he mustered up the courage to step forward and said, "Mother, I want to tell you that Brother Zhang Shi can't actually be an official!"

"Why?" Princess Chengyang was stunned when she heard her son's words.

"It's very simple. Brother Zhang Shi's father abandoned his official position and went to business, so he was the son of a merchant. The Tang Dynasty's laws stipulate that merchants and descendants are not allowed to be officials!" Xue Shao explained, and he was just thinking about this.

"Which bastard is this law?" Princess Chengyang said furiously. In fact, she also knew that there was this law, but she never expected that Zhang Zong was also restricted.

"This... this is what Emperor Taizong said to Fang Xiang himself, and it was later written into the law." Xue Shao said in a low voice at this time.

Princess Chengyang's face turned red. She didn't expect to scold her own father. Zhang Zong and Xue Shao looked at each other. Both of them wanted to laugh but didn't dare to laugh. They were very hard to hold it in.

"Isn't it just a business registration? I'll find someone to change it for you!" Princess Chengyang said again with a little annoyance and angrily.

"Mom, you don't need to change it. Brother Zhang Shi's father was originally an official. According to the Tang Dynasty's laws, if an official is doing business, he will be punished. As long as he stops doing business within three years, he can restore his official status. So you only need to wait patiently for three years. After three years, Brother Zhang Shi will no longer be affected by his business status." Xue Shao spoke again at this time.

"No, I sell flowers and plants now, aren't I also a businessman?" Zhang Zong suddenly asked in confusion.

"It's different. Your father took the initiative to abandon his official position and earned himself a business registration. However, you have just become an adult this year and your hometown can be changed. Your family has its own flower garden. Strictly speaking, it's not a businessman at all. You can say that you are a gardener and a craftsman. You can also say that you are a flower farmer and a farmer. The specific type you belong to depends on how to operate it." Princess Chengyang calmed down and analyzed.

"Yes, it's a trivial matter to change Brother Zhang's family, but many people know that his father abandoned his official position and went to business. There is no way to change this. Even if you forcibly arrange an official position for Brother Shi, if someone takes advantage of this matter in the future, it may be very unfavorable to Brother Shi. So I think you should wait patiently for three years before talking about it!" Xue Shao advised again.

When Zhang Zong heard this, he couldn't help but secretly praised him. He had not cooked so many dishes in vain. In addition to eating, this kid Xue Shao was also very eloquent. But then he thought, Xue Shao's abilities seemed to be all in one mouth?

Princess Chengyang was finally moved at this time. She hesitated for a while before nodding helplessly: "Okay, I have not thought well before, so I won't do this official anymore. Let's talk about business!"

"Business? What business?" Zhang Zong obviously couldn't follow Princess Chengyang's idea. He just persuaded himself to be an official, but why did he get into business in a blink of an eye?

"Of course it's the soap business! Your soap is several times stronger than the pancreas, and it looks beautiful. If it is made and taken into the powder shop, it will definitely cause countless people to snatch it!" Princess Chengyang said with a smile at this time.

"No problem, but how does the eldest princess plan to cooperate?" Zhang Zong understood when he heard this, and immediately nodded in agreement.

In fact, in addition to soap, Zhang Zong also has many ways to make money, such as the method of making sugar and the application of coal, but he had no power before and did not dare to take it out at all. After all, just a two-color rose and flower garden attracted two hungry wolves, Xu Yalang and Liu Jianshi. If he came up with other ways to make money, it would be like a little baby walking in the downtown with gold in his arms. At that time, he might not even know how he died.

"You can make soap, and you don't have to worry about other things. How about half the money you earn in the future?" Princess Chengyang thought for a while and suggested.

"No!" Zhang Zong immediately refused when he heard this, "In Shangyanshang, I just invested in technology and accounted for too much. This is not a long-term solution, so I just need to account for 20%!"

Zhang Zong took the initiative to reduce his shareholding is not pretentious, but a very smart approach, because he planned to treat Princess Chengyang as a long-term partner and would have more businesses to cooperate in the future. He could not take advantage of her every time, so he simply did his business from the beginning. After all, patent investment in later generations only accounted for 20% of the shares.

"Twenty percent is too small, 30% of them, what about you, 30% of them?" Princess Chengyang seemed to have guessed Zhang Zong's thoughts, and said with a smile.

"That's true, Zhang Zong is more respectful than obedient!" Zhang Zong thought about it and agreed readily. Sanqi and Erba are not much different. At worst, just cooperate and give up some benefits in the future.

"By the way, didn't the Tang Dynasty strictly prohibit the nobles and officials from doing business? There would be no problem with the princess doing this, right?" Zhang Zong suddenly thought of Xue Shao's previous words and immediately asked again.

"Hehe, Brother Shi, don't worry, among the nobles in Chang'an City, there are not many shops or industries, such as the Qingmulou we went to before, which is actually the industry of the Ji Wang family." Xue Shao stepped forward and smiled at this time. King Ji Li Yue was Li Shimin's eighth son, and Xue Shao's uncle.

After hearing this, Zhang Zong nodded repeatedly. In fact, he had vaguely heard about some aristocrats doing business before. After all, no matter how strict the law is, it cannot withstand loopholes. The aristocrats in the Tang Dynasty lived a luxurious life. If they had no own industry, they would probably not be able to support the salary paid by the court alone.

It was getting late and the main thing was over, so Zhang Zong got up and said goodbye. Princess Chengyang asked Xue Shao to send Zhang Zong home. As for the soap workshop, he didn't have to worry about it. She would arrange a few craftsmen to go to Zhang Zong's place in a few days. At that time, he only needed to teach these craftsmen to make soap.

"Brother Shi, do you really want to work with my mother to open a workshop?" Xue Shao asked curiously on the way back.

"Of course, didn't I say before that I should earn more money to rebuild my house. Now I don't have enough money." Zhang Zong spread his hands and said, no matter which era, the more money, the better.

"You really plan to build a house, get married and have children?" Xue Shao asked speechlessly.

"Graduating a wife and having children is a bit far away, but building a house is real. The living environment at home is really bad now!" Zhang Zong said with a rare serious expression at this time. Not to mention anything else, there must be a toilet. Now he feels more and more that the toilet is simply the greatest invention in human history.

"I think your place is pretty good, with food and drink, and no one cares about it. It's much better than me." Xue Shao said at the end, and he showed a sentimental look. He was usually too ruthlessly under the supervision of Princess Chengyang. Only when he got to Zhang Zong's place could he completely relax.

"You are the eldest princess' son, so she naturally has to take care of you. If you are just an irrelevant person, I'm afraid the eldest princess won't have to worry about that." Zhang Zong thought for a while and advised him. After all, he was a human being for two lifetimes and could better understand Princess Chengyang's mood.

Xue Shao actually understood Zhang Zong's words, but after hearing this, he sighed and never spoke for a long time. Everyone is suffering. Li Hong once said that he envied Xue Shao very much, but Xue Shao envied Zhang Zong's freedom. Of course, there are things that Zhang Zong envied and unavailable in both of them.

When he returned home, Zhang Zong watched Xue Shao's carriage leave, and then he returned home. Before he had too late, the soap-making items had not had time to clean up. Before it was dark, Zhang Zong rolled up his sleeves and fetched water, cleaned some used items and placed them.

However, when Zhang Zong saw the waste liquid in the pot, he showed a hesitant expression. The waste liquid was left behind after the salt precipitated out of soap. There were still a lot of impurities inside, which looked a bit turbid, like a pot of sewage.

"After the saponification reaction, the waste liquid left behind is actually a mixture of glycerol and water, and glycerol is of great use." Zhang Zong said to himself while touching his chin.

Glycerin is of great use. Not to mention anything else, it is an excellent skin care product. In addition, if nitric acid reacts with glycerin, the famous nitrifying glycerin will be produced. Yes, it is the explosive produced by Nobel.

Although nitroglycerin is famous for explosives, few people actually know that this thing is still a good drug. Its function is to dilate blood vessels and is a special medicine for angina pectoris. In other words, if nitroglycerin can be produced, it can greatly alleviate Li Hong's condition. Combined with dietary taboos, he can even live like an ordinary person and no longer have to worry about the problem of illness.

"Nitrotic acid can be produced, and nitrifying glycerin is not difficult, but..."

Zhang Zong hesitated at this time because he thought of Princess Chengyang's previous warning, Wu Meiniang's ambitious intervention in the government affairs, and Li Hong was her biggest obstacle. If Li Hong died, Wu Meiniang would be the biggest beneficiary. But if he cured Li Hong's illness, he would probably offend Wu Meiniang completely, thus becoming a thorn in the other party's side and a thorn in the flesh.

Save? Or not? Zhang Zong looked at the pot of waste liquid in front of him, and his face also showed a look of great entanglement.
