"Light!" With Li Jie's order, the craftsmen on the hot air balloon immediately ignited the fire, and the shriveled balloon slowly bulged up. The excited Zhu Yunxie ran under the hot air balloon and screamed, wishing he could climb up and fly up immediately. The officials and craftsmen around him also showed excited expressions.

"Li Bandu, have you heard about the affairs in the court?" At this moment, Yuan Jianzheng sneaked up next to Li Jie and asked in a low voice.

"What's the matter?" Li Jie asked without raising his head. After this improvement, many functions of this hot air balloon have been optimized. For example, when landing, they added an iron anchor and threw the iron anchor before landing, so that the hot air balloon does not have to land directly on the ground, which increases a lot of safety.

"It's the matter between the Yu family and the son. Everyone in the court is in danger. Don't you know Li Banju?" Yuan Jianzheng asked incredible. Now, no matter how high or low the officials in the court are, they will discuss this matter as soon as they meet. After all, everyone is worried that His Majesty's butcher knife will fall on his head.

"You Imperial Heavenly Prison is still afraid of being implicated?" Li Jie finally raised his head at this time and looked at Yuan Jianzheng with a smile. The Imperial Heavenly Prison is a very special yamen. They are only responsible to the emperor. They only deal with astronomical affairs in daily life, and they do not have much contact with other officials.

Yuan Jianzheng blushed and then smiled bitterly: "Although our Imperial Heaven Supervision is a clear-water yamen and rarely deals with outsiders in normal times, we are also officials of the court after all."

When he said this, Yuan Jianzheng turned his head and looked around, then lowered his voice again and said, "To be honest with Li Bandu, my uncle's surname is Hu. Although it has nothing to do with that person, I still feel uneasy!"

Li Jie was speechless when he heard this, but he still comforted him: "Zheng Yuan was worried too much. There are so many people in the world with the surname Hu. The Duke of Yue made great achievements in his military affairs. Isn't he also the surname Hu?"

Duke of Yue, Hu Dahai, was also one of the main characters in the legend of the Ming Dynasty. Unfortunately, the novel is a novel after all. Although Hu Dahai in history, he died very early. At that time, Zhu Yuanzhang had not established a country yet. Even so, Zhu Yuanzhang later posthumously named him as Duke. If he lived longer, he might be another Chang Yuchun.

"That's true!" Yuan Jianzheng nodded when he heard this, then chatted with Li Jie for a few more words before he stepped towards the hot air balloon.

However, as soon as Yuan Jianzheng left, he saw the young Guo Zhenglin coming over immediately and said, "Have you heard of Li Bandu?"

"I heard that, do you have a relative's surname Hu?" Li Jie nodded helplessly.

"That's not." Guo Zhenglin thought seriously before answering, "But my father was an official in the same court with that person. Although he had no friendship, he was still aware of him. I am really afraid that the Jinyiwei would find something. You said that if it was..."

"Brother Guo, do you know who recommended that person as prime minister?" Before Guo Zhenglin finished speaking, Li Jie interrupted him in a faint tone.

Guo Zhenglin was stunned at first, and then suddenly remembered that Li Jie's grandfather was Li Shanchang, and Hu Weiyong was promoted by Li Shanchang. In comparison, what's wrong with his father is nothing?

"This... Brother Li... is so sad... it's not right... If you relax, you will definitely be fine!" Guo Zhenglin was also frightened and said incoherently, but in the end he began to comfort Li Jie.

Li Jie was also amused and cried, and then sent Guo Zhenglin away again, but unexpectedly someone came over again.

"Are you a semen person afraid of being implicated?" Li Jie asked speechlessly as he looked at Mahama who came over.

"I'm afraid, Li Bandu, have you forgotten that one of the crimes of that person was colluding with the Mongol Yuan?" Mahama said nervously.

"What does this have to do with you?" Li Jie looked puzzled after hearing this.

"Of course it's related. When the Mongol Yuan fled to the grassland, he took away many semen officials. There were also many semen people in our Ming Dynasty. I heard that that person colluded with the grassland and used semen to convey the message." Mahama was frightened at the end. They were frightened. Their semen life was not easy. If this crime was confirmed, God knows how many people would fall to the ground because of it?

"Where is this?" Li Jie was completely speechless. Hu Weiyong was charged with many crimes of rebellion. He colluded with the Mongolian Yuan in the north and secretly contacted Japanese pirates in the south. Almost all the Ming enemies had an affair with him. God knows where he got his energy?

Just then, Zhu Yunxiu rushed over and shouted excitedly at Li Jie: "Li Bandu, the hot air balloon is flying, can I go up?"

Only then did Li Jie realize that the hot air balloon's airbag had already flown up, but the hanging basket was still fixed to the ground. Today was the first test flight after the hot air balloon was improved, and all the relevant personnel came.

"Your Highness, even if I agree, the guards around you will not agree, so unless it is Your Majesty or the Prince nodded, you should give up this idea." Li Jie spread his hands and said helplessly, and Mahama next to him also left with great tactfulness.

Zhu Yunxi immediately showed a depressed look. He was far away when the hot air balloon was launched last time, so it would be fine if he couldn't catch up, but this time he was in front of him, but he could only watch it, which made him very unwilling to accept it.

"Okay, although you can't go up, I can hand over a task to you." Li Jie couldn't bear to see Zhu Yunyu disappointed, so he said with a clever inspiration.

"What task?" Zhu Yunhuang became interested again.

"Did you see the cable under the hanging basket? We will cut the cable later. What if you let you do it yourself?" Li Jie pointed at the bottom of the hanging basket and said.

"That's it?" Zhu Yunxiu was still a little disappointed when he heard this, but compared to watching, cutting off the cable was at least considered participating in the takeoff of the hot air balloon.

The time for takeoff was up, and Li Jie also ordered the cable to be cut off again. Zhu Yunqiu personally carried the axe. When the cable was cut off, the hot air balloon took off again. However, this time the hot air balloon was Guo Zhenglin, and there were three officials from the Imperial Academy. They would not fly too far, because this time it was mainly to test the improved functions of the hot air balloon and let them try to control the position of the hot air balloon landing.

When the hot air balloon takes off, there will be nothing Li Jie has to do. In fact, he has long stopped participating in the improvement of the hot air balloon. After all, he has no energy to do these things now. There are so many talents in the Imperial Heaven Supervision, and they can take over the follow-up matters.

It was getting late, Yuan Jianzheng and others went to chase the hot air balloons, and Li Jie also assigned some homework to Zhu Yun's house and asked him to finish it after he went back, and he would check it tomorrow.

Recently, Li Jie has been teaching Zhu Yunyu mathematics, which is actually quoting the numbers and operation symbols of later generations to replace the problems of text in Central Plains arithmetics.

Zhu Yunyu had a foundation in mathematics, and he was quite talented in this area. He learned a little in just a few days, especially with great experience in the use of tables. Now he took over the accounts of the Glass Workshop and the Qianliyan Workshop, and cultivated a group of clerks who knew how to use numbers and symbols. In this way, Zhu Yunyu became much more relaxed.

After saying goodbye to Li Jie, Zhu Yunyu also returned to the palace in a carriage and came to see his father Zhu Biao as usual. Since Zhu Biao untied his knot last time, he has been more concerned about Zhu Yunyu and will ask about his experience outside every day.

However, when Zhu Yunyu found Zhu Biao in Wenhua Palace, he found that he was buried in the document with a group of officials. Everyone was in high books in front of him, and the officials were full of fatigue. It was probably been busy for a long time, but Zhu Biao was still urging him and he kept writing, and even Zhu Yunyu didn't even notice it when he came in.

"Meet my father!" Zhu Yunxiu was surprised when he saw so many people, but he still saluted Zhu Biao first.

"Yun Yu, you are back. Sit down and rest first. I'll finish my work!" Zhu Biao said without raising his head. The desk in front of him was filled with books. These were the tasks assigned to him by Zhu Yuanzhang. All the accounts of the treasury were sent to Wenhua Hall. Even though Zhu Biao had summoned so many people, he still didn't know when it was going to be?

Seeing that his father was so busy, Zhu Yunxiu couldn't bother him anymore, so he sat aside obediently. However, after waiting for a while, Zhu Biao was still busy, as if he had forgotten his son, which made Zhu Yunxiu feel a little bored, so he simply picked up the booklet on the desk and flipped it out.

As a result, Zhu Yunxiu realized that all these books were account books, such as the account book in his hand, which was the income and expenditure accounts of a royal village outside the city.

If it were in the past, Zhu Yunqiu would not understand it at all, but he had been dealing with the account book during this period and had long been familiar with the account book. In addition, he was bored, so he simply took the paper and pen and began to sort out the number on the account book.

The ancient books looked very thick, but in fact the records were all written. For example, the imperial books in Zhu Yunyu's hand were all filled with "How much food was collected on a certain day, how much money was sold, how much money was sold on a certain day, how much did it cost to buy agricultural tools on a certain day". Most of them were written, and there were actually very few numbers that were really useful.

In addition to Zhu Yunxi's exercise during this period, he quickly calculated the account book, then marked it and threw it aside, picked up another one and started to calculate it.

Zhu Biao was also calculating the accounts settled by his officials. It took him a long time to remember Zhu Yunxi, which made him raise his head immediately, but was shocked to find that Zhu Yunxi was sitting not far away, and he was writing and calculating with paper and pen, as if he was also calculating the accounts?

Zhu Biao was also very curious now, so he stood up and walked to Zhu Yunxiu. When he saw what his son wrote, he frowned because he found that he couldn't understand what Zhu Yunxiu was writing at all?
