Quick travel: I am bound by the longevity system

"Thank you for your concern, mother and concubine. My son likes it very much."

"As long as you like it, Bitao, let the kitchen pack some and send them to the fourth prince's house." De Zhaoyi ordered with a smile.

"Yes." Manager Wang responded softly.

"Mother concubine, mother concubine."

Qi Mingchen was about to say something when he saw Qi Mingzhan running in happily, holding an envelope in his hand.

"Mother, my son has a new son from Fourth Brother... Fourth Brother, you are back."

What Qi Mingzhan was about to say stopped abruptly when he saw Qi Mingchen, and then instinctively hid the letter in his hand behind his back.

"Well, I just came back today." Qi Mingchen looked at Qi Mingzhan and said, "What is that in your hand?"

"No...nothing, it's just a letter written by Brother Six to me."

Qi Mingzhan wailed in his heart, it was over, if the fourth brother knew that he, the sixth brother and Lin Jiu were inquiring about him, and they were inquiring about his bad things, he would definitely be punished by the fourth brother.

Qi Mingchen definitely didn't believe Qi Mingzhan's words. He had just heard this kid talk about him, but he didn't continue to ask. Although his brother was simple-minded, he had a beast-like intuition about people's hearts. He didn't need to worry. He was being taken advantage of.

"Bitao, tell the small kitchen to prepare more of what the two princes like to eat, and send someone to the food supervisor to tell them that today the fourteenth prince will eat in Ren'an Hall, so there is no need to prepare separate meals."

"Yes."

After the king saluted, he walked out of the hall.

"Fourth brother, you came back just in time. I just have a lot of questions that I want to ask you." Qi Mingzhan sat down close to Qi Mingchen and said.

"But what's the problem?"

"Well, Dr. Zhang from Taixue University left an arithmetic question yesterday. He said that the sum of nine consecutive numbers is nine hundred and ninety-nine. What are these nine numbers? Dr. Zhang asked us to use the simplest calculation. The calculation process, but I couldn’t figure it out after thinking about it for a long time. I asked Brother Ninth, and Brother Ninth said he didn’t know it either.”

Qi Mingchen pondered for a while and then said: "Since it is the addition of consecutive numbers, there must be rules between them. Regardless of these nine numbers, we can look at some simple ones, such as what is the sum of one, two, three, four and five."

"I can do this, it's equal to fifteen." Qi Mingzhan said with a smile.

"That's right. How did you calculate it?"

"Just add it directly."

"But I have a simpler method here. Look, is this three the middle number of these numbers? Is this two one less than three, and four is one more than three. Let's give one of four to two. , then does it become three? In the same way, if you take two of five and give it to one, does it become two more threes? Add three to the original three, how many threes are there in total?"

"It's five, three and fifty-five. So to ask for these nine numbers, we need to count the middle number first. The middle number is one hundred and eleven, so the nine numbers are one hundred and seven, one hundred and eight, and one." One hundred and nine, one hundred and ten, one hundred and eleven... one hundred and fifteen."

"Yes, the response is very fast. You see, as long as you find the right method, these questions are not difficult." Qi Mingchen smiled and nodded.

Seeing this, Qi Mingzhan asked Qi Mingchen several questions in succession. Each of these questions was more difficult than the last, but Qi Mingchen could solve them easily.

"Fourth Prince, Fourteenth Prince, it's time for dinner."

"I'll come here first today. If you don't understand anything, come and find me at my house." Qi Mingchen gave a rare smile.

"Fourth brother, you smiled."

"You're wrong." Qi Mingchen looked away uncomfortably, but his ears turned red.

Qi Mingzhan was amused: what the fourth brother said to sister Lin Jiu was indeed somewhat duplicitous.

Dingzhou Prefecture

"Ajiu, I just received news that Princess Silla led her old troops into the royal city of East Korea, and East Korea was destroyed by Silla. Princess Silla supported the young emperor to ascend the throne, and she became the regent princess."

Qi Mingjing came to Lin Jiu immediately after learning that Donghan had been destroyed.

"It's a little later than I expected."

"After all, not everyone is Ajiu." Qi Mingjing said with a smile.

Lin Jiu picked a chrysanthemum and held it in his hand, "Get ready! It won't be long before Silla's side submits its credentials."

Qi Mingjing brushed the green ball in front of him with his hand, "The flowers Ajiu raised are beautiful. I wonder if I can give them to Jing."

"If you like any pot, take it back!"

"But I only love this branch in Ajiu's hand."

"Qi Mingjing, civil servants and generals are destined to be fruitless, so why do you waste your time on me?"

"Ajiu has never tried it, so how can he know that there is no result." Qi Mingjing put the flower in Lin Jiu's hand into his arms and said: "As long as Ajiu is single for one day, then I still have a chance. I said, even if It’s okay to be Ajiu’s guest. Anyway, I won’t give up.”

"Why bother?"

…………

In the winter of the 31st year of Taikang, Silla submitted its credentials to Daqi, expressing its willingness to become a vassal and pay tribute to Daqi, regard Daqi as its suzerainty, and ask the king of Daqi to grant Silla a title.

After receiving the credentials submitted by Silla, Emperor Taikang consecrated the new king of Silla as the King of Silla, and the princess of Silla as the regent princess, and was given a gold seal.

After receiving the golden seal from Da Qi, the King of Silla burst into tears of gratitude, and wrote a letter saying that he wanted to send some students to study in the Central Plains. Emperor Taikang readily agreed and ordered Lin Jiu and Qi Mingjing to escort the Silla envoy to Chang'an to study.

Lin Jiu didn't understand why Emperor Taikang asked her to return to Chang'an. To know how to escort the envoy, Qi Mingjing only needed to lead the team. However, the emperor's order was such that Lin Jiu had to arrange things in Dingyuan Mansion even if she was unwilling. OK, I picked up the envoy and went to Beijing with Qi Mingjing.

"Meet the sixth prince."

"Tingzhu, I have something to talk to your master about. Could you please pass it on?"

"Tingzhu, please invite the sixth prince to come in."

Since the last incident, Lin Jiu has been trying to meet Qi Mingjing as little as possible on the pretext of being busy, but now that he is in the team heading to Beijing, he can't avoid seeing him! .

Qi Mingjing walked into the room, and Tingzhu and Xing'er stepped back knowingly.

"Ajiu is willing to see me this time." Qi Mingjing's words contained a hint of resentment.

"I have met the Sixth Prince." Lin Jiu bowed to Qi Mingjing politely and said, "The Sixth Prince is overly worried. The official is not avoiding the Sixth Prince, but he was busy arranging autumn planting and wintering some time ago. The Sixth Prince also knows It's cold in the north, and many people spend the winter in the north for the first time, so they have to take care of themselves."

"I'm still Ajiu, so you don't want to see me?" Qi Mingjing said, "Ajiu used to call me Mingjing in private, but now he is estranged from me again. Could it be that Ajiu is angry because of what happened last time."

"The Sixth Prince is a nobleman of the Emperor and Heaven, and is the superior of the lower official. There is a difference between superiority and inferiority. In the past, the lower official was frivolous. But he will not be the same in the future."

Lin Jiu believed that the reason why Qi Mingjing was interested in her was due to the friendship between her when she was a child. After Qi Mingjing discovered that she was no different from other people, this thought faded away.
