My father is Yongzheng, and I am Qianlong?

Chapter 6 Hongli's Mathematics Test
Hongli then explained to Niohuru the reason why Haitang came to him.

After hearing what Hongli said, Niohuru was naturally very happy and expressed her gratitude to his wife Ulanara.

But it wasn't long before Hongli learned that Yongzheng had suddenly returned home and wanted to see him after dinner.

Hongli had no choice but to go to Yongzheng's study after dinner.

Yongzheng did make a sudden decision to return home.

After he came back, he first met with Pan Shiquan secretly.

"Mr. Pan, I have good news to tell you. Nian is pregnant again!"

After meeting Pan Shiquan, Yongzheng first told a piece of news with a smile.

After hearing this, Pan Shiquan stood up with a delighted expression and bowed, "Congratulations, Fourth Master!"

Yongzheng waved Pan Shiquan to sit down and said, "I have already sent a letter to someone to quietly pass this news to Nian Gengyao."

Pan Shiquan said with a smile, "Now that Nian has just given birth to a son for the Fourth Master, and now she's pregnant again, I think Nian Gengyao, the Governor of Sichuan and Shaanxi who controls the food supply of the Northwest Army, will have to pay more attention to you, the Fourth Master."

Yongzheng nodded and sighed, "This slave is very slippery. It's difficult to make him obey without some practical means to tie him up."

"What the Fourth Master said is true, but in my humble opinion, the Fourth Master cannot just focus on Nian Gengyao. The palace must also make some subtle preparations."

Pan Shiquan reminded Yongzheng again at this time.

Yongzheng stood up thoughtfully and began to pace around the room. After a moment's silence, he agreed, "Mr. Pan is right. If I stay at home like this and don't go out anymore, it will be easy for people to forget me. I'm afraid Khan Ama will also forget me, the fourth son. There must be someone by Khan Ama's side to let him know of my existence."

"Today, while I was teaching the emperor's grandchildren, I encountered something. I must tell the Fourth Master about it."

Pan Shiquan smiled and spoke at this time.

Yongzheng turned around and looked at him: "What's the matter?"

Pan Shiquan stood up with a serious look on his face: "It was Hongshi who bullied Hongli, and Hongli chose to endure it."

Pan Shiquan then told Yongzheng what he had witnessed.

After hearing this, Yongzheng said meaningfully: "In that case, Hongli is indeed suitable to stay by Khan Ama's side, so that Khan Ama can often think of me, the fourth prince who lives in seclusion and devotes himself to Buddhism."

"That's right. Hongshi's recklessness is also good for the Fourth Master. The Fourth Master can turn a blind eye to him for now. This way, people will know that you are really so focused on studying Buddhism that you don't even care about disciplining your family."

Pan Shiquan said.

Yongzheng nodded, his expression cold, and said, "Let's just indulge this bastard for a while longer!"

Yongzheng met Hongli in his study only after meeting Pan Shiquan.

Wang Wang!

Wang Wang!

When Hongli came to Yongzheng's study, he heard the barking of dogs one after another.

He looked through the fence on the side of the study and saw that there was a small garden behind the fence with many dogs, all of which were very clean. Because he seldom came here, these dogs were unfamiliar with him and barked at him.

Seeing this, Hongli simply walked towards the dogs.

He knew that Yongzheng liked to keep dogs, so when he came to see Yongzheng, he specially asked Haitang to bring a braised bone and put it in the food box.

As soon as Hongli came over, he threw the bone in.

The dogs started fighting madly over the food.

At this time, Hongli also entered Yongzheng's study.

As soon as Hongli came in, he saw that Yongzheng's study was spotless, without a speck of dust anywhere, and everything was arranged in an orderly manner.

What surprised him was that there was a dog lying next to Yongzheng. The dog was relatively quiet, with a snow-white body and only two eyes as black as lacquer, staring at Hongli.

Yongzheng was holding a string of Buddhist beads in his hand and combing the dog's hair, while also copying Buddhist scriptures with a pen.

Those who don’t know the historical ending would think that this cold-faced king was really discouraged and no longer cared about all the struggles for power and profit in the world. He only copied Buddhist scriptures and played with dogs.

But in fact, what the princes, ministers and aristocratic elites of the Qing Dynasty would never have thought of was that this was a ruthless person who had been patient for a long time for the sake of the Qing Dynasty's foundation, and who would stab his own people, including his clan brothers, with the blade of reform in the future!
Hongli naturally did not object to Yongzheng doing this.

What's more, he is still Qianlong now, so he naturally hopes that Yongzheng's reforms will be as drastic as possible, so that he can save more capital for squandering.

"Sit down. There's a test paper on the table. Give it to me after you've finished it."

When Hongli came, Yongzheng did not look up, but just copied the Buddhist scriptures seriously. He raised his left hand holding the Buddhist beads, pointed to a test paper on the table, and gave an order.

"Whoo!"

After Hongli responded, he went to sit down at the table.

On the desk, in addition to a test paper, there were also pens, ink, paper, and inkstone, as well as a bright candle lamp, an abacus, and draft paper.

Hongli took a look at the test paper and found that it was a math paper. Many of the application questions were quite practical, all related to the water transport, river management, construction, disaster relief, and grain transportation for combat in this era.

Hongli didn't expect that Yongzheng suddenly called him to give him a math test.

In his previous life, he was the one who set questions to test others, but now, others are the ones testing him.

But Hongli still answered the questions seriously.

For Hongli, these questions, though likely carefully prepared by Yongzheng, were not at all difficult. The only irritation was that he had to convert some numbers into Arabic symbols and translate some logarithms and trigonometric functions represented by Chinese characters into Roman characters.

After all, the mathematics he learned later was no longer expressed purely in Chinese characters.

Only after translating it once could he perform calculations and solve the problem.

Although Yongzheng was copying Buddhist scriptures, he was also paying attention to Hongli's answers.

He noticed that Hongli had drawn many unknown drawings on the draft paper. These drawings included straight lines, arcs, and even dotted lines, as well as some text symbols that he had only seen from Lao Jiu.

Because Kangxi's ninth son, Yinzhen, was proficient in foreign languages.

"Who did you learn these strange symbols from?"

Yongzheng appeared behind Hongli at some point and started asking.

Hongli stood up and replied, "My son learned this by reading some books written by foreign missionaries."

Yongzheng didn't ask any more questions.

After a while, Hongli handed the finished paper to Yongzheng: "Father, I have finished it."

Yongzheng took the test paper, took out the slip of paper with the answers from his sleeve, and then compared them with Hongli's answers one by one.

“They are all correct!”

"These are puzzles based on the Essence of Mathematics. Your Sixteenth Uncle spent several days to get them all right."

Yongzheng looked at Hongli in disbelief.

The sixteenth uncle that Yongzheng mentioned was the sixteenth brother Yinlu, who had always been loved by Kangxi for his proficiency in mathematics and was now in charge of the Algorithm Museum in the palace.

then.

Yongzheng snatched Hongli's draft paper and examined it carefully. Then, he pointed at some arrows and asked Hongli, "What are these?"

"My son calls this a vector! It can be used to create coordinates when calculating three-dimensional objects."

As he spoke, Hongli explained this concept in detail to Yongzheng.

Yongzheng nodded solemnly as he listened, then took Hongli's arm with both hands and said, "Hongli, I didn't expect you to be so talented in mathematics and physics that you even want to create a new theory!"

"But you should know that during every grand celebration, your Khan will select those young princes and grandchildren who have outstanding expertise in a certain field and keep them by his side to train. If you can truly attract his attention with your mathematics this time, you might be able to stay in the palace to accompany the emperor. If you can, it will be beneficial to you and to our Prince Yong's Mansion as well. Therefore, Father hopes that you can do this and successfully stay in the palace to accompany the emperor."

"My son knows."

"But I wonder if there will be any prince or grandson who is even more outstanding in mathematics and physics than my son."

Hongli said.

Yongzheng said, "Probably not. Your third uncle's family focuses more on Confucianism. Your ninth uncle's family, although proficient in these foreign characters, is not used in mathematics. Your sixteenth uncle is proficient in mathematics, but he was the one who set these questions. You should know his level."

Hongli nodded.

He knew that Yongzheng hoped that he could help him in his fight for the throne, so he replied: "Don't worry, father. If I can accompany you, I will behave well and let Khan Mafa know your hard work."

Yongzheng smiled and said, "Go and have a rest."

Hongli returned to his own courtyard and slept soundly that night with Haitang as his pillow.

The next day.

He still went to school to study as usual.

Because Hongshi often went to the Eighth Prince's Mansion, Hongli often read and wrote with Hongzhou, and they gradually became more familiar with each other.

In the blink of an eye, it was the birthday of Hongli and Hongzhou.

In previous years, when Hongli and Hongzhou celebrated their birthdays, few people gave them gifts.

But what was different this year was that Hongli received quite a lot, so he had to get up early in the morning and go to each room to express his gratitude.

However, Hong Zhou still received very few gifts.

Fortunately, Hongli specially prepared a gift for Hongzhou that was more generous than in previous years.

Hong Zhou was so happy.

Especially when Hong Zhou learned that Hong Shi only celebrated Hong Wang's birthday in the first month of the 60th year of Kangxi's reign, but not his own, he said to Hong Li with great emotion: "Fourth brother is still good to me!"

Because the Bannermen have strict rules, who gives gifts and who does not will be regarded as a very serious matter.

When Yongzheng learned that among his brothers, only Hongli had sent a gift to Hongzhou, and Hongshi had not sent any gift in return to celebrate Hongwang's birthday, his face turned as dark as the bottom of a pot. On the day of the Banquet for Thousand Elders to celebrate the 60th anniversary of Kangxi's reign, he ordered that only Hongli, his son, be brought into the palace.

Hongli took the special gift that Yongzheng asked him to prepare and followed Yongzheng into the palace.

"Reporting to Khan Ama, the gift presented by my son, the Four Princes' Palace, is a gift prepared by the Emperor's grandson, Hongli. This gift should not be announced to the public. Khan Ama, please review it personally."

When it was Yongzheng's turn to present a gift from Prince Yong's palace, he specially brought Hongli to Kangxi's palace and started talking, which really whetted Kangxi's appetite.

But what made Hongli laugh was that he had never expected that the "Veda Theorem" known to all middle school students in later generations would become a mysterious gift to Kangxi.
