"Ignition!" With Li Jie's order, the craftsman on the hot air balloon immediately ignited, and the shriveled balloon slowly puffed up, and the excited Zhu Yunxi ran under the hot air balloon and shouted, eager to climb up and fly up immediately, and the surrounding officials and craftsmen also showed excited looks.

"Li Banyu, have you heard about the affairs of the court?" At this moment, I saw Yuan Jian sneakily leaning 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, such as when landing, they added an iron anchor, and threw down the iron anchor before landing, so that the hot air balloon does not have to land directly, which has increased a lot of safety.

"It's the matter of Yu's father and son, the hundred officials in the court are already in danger, Li Banyu, don't you know?" Yuan Jian Zheng asked with an incredulous face, no matter how high or low the officials of the court are now, as long as they meet, they will discuss this matter, after all, everyone is worried that His Majesty's butcher's knife will fall on their heads.

"Are you Qin Tianjian still afraid of being implicated?" Li Jie finally raised his head at this time, and looked at Yuan Jian Zhengdao with a smile, Qin Tianjian is a very special yamen, they are only responsible to the emperor, and they usually only deal with astronomy, and they don't have much contact with other officials.

I saw that Yuan Eunuch's face was red, and then he also smiled bitterly: "Although our Qin Tianjian is a Qingshui Yamen, we really rarely deal with outsiders, but we are also officials of the imperial court. ”

When he said this, he saw that Yuan Jian was turning his head to look around, and then he lowered his voice again and said: "Don't hide it from Li Banyu, my mother's uncle's surname is Hu, although it has nothing to do with that person, but I still don't feel solid in my heart!" ”

Li Jie was also a little speechless when he heard this, but he still comforted: "Yuan Jian is thinking too much, there are so many people with the surname Hu in the world, and the Duke of Yue has made great achievements in war, isn't he also surnamed Hu?" ”

Hu Dahai, the Duke of Yueguo, is also one of the main characters in the biography of the heroes of the Ming Dynasty, but unfortunately the novel is a novel after all, although Hu Dahai in history is heroic, but he died very early, at that time Zhu Yuanzhang had not yet established the country, even so, Zhu Yuanzhang later posthumously named him the Duke of the country, if he lived longer, maybe it would be a common spring.

"That's just as well!" Yuan Jian Zheng nodded when he heard this, and then chatted with Li Jie for a few more words, and then walked towards the hot air balloon.

However, as soon as Yuan Jianzheng left, he saw the young Guo Zhenglin immediately come over and said, "Have you heard of it?" ”

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

"Not really." Guo Zhenglin thought about it seriously and then replied, "But my father was an official in the same dynasty as that person, although he didn't have any friendship, but he knew each other, I was really afraid of being found out by Jinyiwei, you said it was ...... if it happened."

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

Guo Zhenglin was stunned for a moment, and then suddenly remembered that Li Jie's grandfather was Li Shanchang, and Hu Weiyong was picked up by Li Shanchang.

"This ...... Brother Li...... Mourning...... Wrong...... Relax, you'll be fine! Guo Zhenglin was also frightened and incoherent, but finally began to comfort Li Jielai.

Li Jie also couldn't cry or laugh, and then sent Guo Zhenglin away again, but he didn't expect someone to come over again.

"You're a lustful person who is afraid of being implicated?" Li Jie looked at Ma Hama who came over and asked speechlessly.

"I'm afraid, Li Banyu, have you forgotten that one of that person's crimes is collusion with Meng Yuan?" Maha said nervously.

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

"Of course it has something to do with it, when Meng Yuan fled to the grassland, he took away a lot of Semu officials, and we also have a lot of Semu people here in Daming, I heard that that person colluded with the grassland, and he used Semu people to deliver news." Maha also looked frightened in the end, their life was already not easy, if this crime is confirmed again, God knows how many people will fall to the ground because of this?

"Where is this?" Li Jie was completely speechless, Hu Weiyong was accused of rebellion, colluding with Meng Yuan in the north, secretly communicating with the Japanese in the south, almost all the enemies of the Ming Dynasty had a leg with him, God knows where he got the energy?

At this moment, I saw Zhu Yunxi rushing over and shouting excitedly at Li Jie: "Li Banyu, the hot air balloon is flying, can I go up?" ”

Li Jie only found out at this time that the airbag of the hot air balloon had flown up, but the hanging basket was still fixed on the ground, and today was the first test flight after the improvement of the hot air balloon, and all the relevant personnel came.

"Your Highness, even if I agree, the guards around you don't agree either, so unless Your Majesty or the Crown Prince nods, you should dispel this idea." Li Jie spread his hands and said helplessly, and Ma Hama next to him also left very interestingly.

Zhu Yunxi immediately showed a depressed look, he was far away when the hot air balloon was lifted off last time, and it didn't matter if he couldn't catch up, but this time it was in front of him, but he could only watch, which made him very unwilling.

"Okay, although you can't go up, I can give you a task." Li Jie couldn't bear to see Zhu Yunxi disappointed, so he had an idea.

"What task?" Zhu Yunxi said with interest again.

"Do you see the cable under the gondola, we're going to cut the cable later, how about you do it yourself?" Li Jie pointed to the bottom of the hanging basket.

"That's it?" Zhu Yunxi was still a little disappointed when he heard this, but compared to watching dryly, cutting the cable can at least be regarded as participating in the take-off of the hot air balloon.

When the time for take-off came, Li Jie also ordered to cut the cable again, Zhu Yunxi personally carried the axe, and when the cable was cut, the hot air balloon rose into the air again, but this time it was Guo Zhenglin who drove the hot air balloon, and there were also three officials from Qin Tianjian, and they would not fly too far, because this time the main thing was to test the improved function of the hot air balloon, and let them try to control the position where the hot air balloon landed.

When the hot air balloon takes off, there will be nothing to do with Li Jie, in fact, he has long stopped participating in the improvement of the hot air balloon, after all, he doesn't have the energy to do this now, Qin Tianjian has so many talents, they can take over the follow-up things.

It was not early, Yuan Jian was chasing the hot air balloon, and Li Jie also assigned some homework to Zhu Yunxi, asking him to finish it when he went back, and he would check it tomorrow.

Recently, Li Jie has been teaching Zhu Yunxi mathematics, which is actually to quote the numbers and operation symbols of later generations to replace the problems full of words in the Central Plains arithmetic.

Zhu Yunxi already has a foundation in arithmetic, and he is also quite talented in this area, he has learned few things in just a few days, especially for the use of forms is very experienced, and now he has taken over the accounts of the glass workshop and the clairvoyance workshop, and has trained a group of scribes who know how to use numbers and symbols, so that Zhu Yunxi is much easier.

After saying goodbye to Li Jie, Zhu Yunxi also returned to the palace in a carriage, and came to see his father Zhu Biao according to his previous habits.

However, when Zhu Yunxi found Zhu Biao in the Wenhua Palace, he found that he was buried in the case with a group of officials, everyone had a tall book in front of them, and the officials were also full of exhaustion, it is estimated that he has been busy for a long time, but Zhu Biao is still urging, and he is also writing non-stop, and he didn't even notice that Zhu Yunxi came in.

"Meet Father!" Zhu Yunxi was also strange when he saw so many people, but he still saluted Zhu Biao first.

"Yunxi, you're back, sit down and rest first, I'll talk about it after I'm done with some things!" Zhu Biao didn't raise his head, and the bookcase in front of him was also full of books, these were the tasks given to him by Zhu Yuanzhang, and all the accounts of the entire internal treasury were sent to the Wenhua Palace, even if Zhu Biao summoned so many people, but he didn't know when it would be?

Zhu Yunxi saw that his father was so busy, and he couldn't bother him anymore, so he sat aside obediently, but after waiting for a while, Zhu Biao was still busy, and seemed to have forgotten about his son, which made Zhu Yunxi feel a little bored, so he simply picked up the book on the bookcase and flipped through it.

As a result, Zhu Yunxi found out that these books were all account books, such as the account book in his hand, which was the income and expenditure account of an imperial village outside the city.

If it was placed in the past, Zhu Yunxi couldn't understand it at all, but during this time, he had been dealing with the account book, and he couldn't be more familiar with the account book, plus he was also idle and bored, so he simply took a pen and paper and began to sort out and calculate the number on the account book.

The ancient ledger looks very thick, but in fact, the records in it are all in words, such as the Huangzhuang ledger in Zhu Yunxi's hand, which is all "how much grain was collected on such and such a day, how much silver money was folded, and how much money was spent on buying farm tools on such and such a day", most of which are words, and there are very few really useful numbers.

Coupled with Zhu Yunxi's exercise during this time, he quickly calculated this account book clearly, then marked it and threw it aside, and picked up another one and counted it.

Zhu Biao was also calculating the accounts settled by his officials, and it took a long time for him to suddenly remember Zhu Yunxi, which made him raise his head immediately, but he was shocked to find that Zhu Yunxi was sitting not far from him, and he was also holding a pen and paper to write and calculate, as if he was also calculating the accounts?

At this time, Zhu Biao was also very curious, so he stood up and walked to Zhu Yunxi's side, but when he saw what his son wrote, he frowned suddenly, because he found that he couldn't understand what Zhu Yunxi was writing at all?
