The June evening breeze still exudes a hint of coolness, and the chirping of crickets sets off the more than a dozen feet of stargazing platform even more silent. At this time, most of the Chang'an City is full of bungalows, and the entire Chang'an City can be seen at a glance when standing on the platform.

The sunrise and the horizon warp stand on the platform, and the stars of the "Three Walls and Twenty-eight Nights" in the sky twinkle. Taishi Ling Fu Yi was looking up at the sky on the stargazing platform at this time, adjusting the armillary sphere in his hand from time to time to observe the Taibai Star. After half an hour, I walked to the next room, and wrote down the calculations on the paper by the candlelight in the house.

As soon as he put down his pen, the guard guarding the stargazing platform came up and said to Fu Yi: "Mr. Fu, there are a few people in the audience looking for you."

Fu Yi was stunned, the department he stayed in was the famous Qingshui Yamen in Chang'an, and it was worthless except for the fact that these things on the table were worth a little money, so few people asked him to do anything.

"Then bring it up" Before the words fell, I saw a young man with a few people very impolitely climbed onto the stargazing platform, the young man panted and saw Fu Yi and asked: "Mr. Fu has you ever seen a saint in recent days?" ”

Fu Yi was confused by a nonsensical sentence, but out of etiquette, Fu Yi still said: "No", seeing that Fu Yi had not yet gone to see Li Yuan, Xiao Zheng's hanging heart was relieved.

There is no way not to be in a hurry, before the change of Xuanwu Gate, Fu Yi once secretly played Li Yuan after observing the celestial phenomena: "Taibai sees Qin Fen, and the King of Qin should have the world", this secret report was submitted to Li Yuan and almost stirred up this matter.

"That's good!" The young man patted his chest and said happily, and then bowed to Fu Yishen and said: "Mr. Fu, don't blame, I am a hidden family in the rivers and lakes, surnamed Xiao, I have also learned some arithmetic since I was a child, and I have been opposed to ghosts and gods since I was a child, and I have come to ask Mr. Fu for arithmetic problems today."

Knowing what this Mr. Fu Yi likes, Xiao Zheng said a word to this guy's heart. Hearing Xiao Zheng's words, Fu Yi's eyes lit up, and his rudeness and unhappiness towards Xiao Zheng just now suddenly disappeared.

I saw Xiao Zheng take out two booklets from his sleeve and hand them to Fu Yi and said: "Mr. Fu, this is arithmetic, one is called algebra, and the other is called geometry, please give me some advice."

By the light of the lantern, Fu Yi flipped through the two books, he didn't know what some strange characters in algebra were, but he could still understand a few things in geometry, and Fu Dali, who was quite researched, ignored everyone and pondered.

After waiting for a while, I saw Xiao Zheng smile and said: "Mr. Fu, these two books are being sent to Mr. Xia, and I also know the calculation method of the orbit of the stars, if Mr. doesn't mind, you can ask Mr. to go to the house to discuss one or two, but I want to be a little wronged Mr."

"What?! You say you know how to calculate the orbits of stars? ”。

"It is absolutely true that the orbits of this star are mostly elliptical rather than circular." Elliptical? Fu Yi stood in place, closed his eyes, thought carefully for a while, and said: "No wonder this is the case, in this case, it makes sense to have this astral displacement."

"Okay, the ancients Yun Chao heard that it is okay to die at night, there is no money left in the next family, and he is open, as you said it is true, I will go now", Fu Yi was blindfolded and followed Xiao Zheng into the car, and the next day, Fu Yi's family received a letter from Fu Yi, saying that he was discussing arithmetic with his friends and returning to ....... after a while.

"Sun Tzu's Art of War has a cloud: profit and temptation, chaos and take, real and prepared, strong and avoid. Now it's time for us to take it from the mess," Li said.

"Presumably, the virtuous brother also knows that Chang He, the general of the Xuanwu Gatekeeper, was originally a general of Li Shimin, the king of Qin, and was later promoted to the Xuanwu Gate Guard. Although the crown prince Li Jiancheng tried his best to make friends with Chang He under the instruction of Wei Zheng, so that he was still a confidant of my family, it was not difficult to arrange for our armor to enter the Xuanwu Gate," Li Shi said to Xiao Zheng with a wink.

"With the soldiers, I can't get to His Highness in the next way, admire! But then it depends on how His Royal Highness will introduce the two into the Xuanmen" He raised a big finger at Li and praised, and Li Hongguang was full of praise in one sentence.

"Brother, do you know that King Qi has an affair with Zhang Jieyu in the harem?" Li Shimin smiled evilly, and with the fire of gossip in his eyes, he approached Xiao Zheng and whispered.

Xiao Zheng glanced at Li Shimin, thinking that your descendants snatched their daughters-in-law and picked up ashes, and raised male pets in a flock This history book has a name, and it is estimated that it is passed down from your roots, and it seems that this guy is not a good bird in life.

"When our armor warriors trained back from Shenhe Bay are ambushed, I will go and expose this matter to the sage, and when they enter the palace to confront them, Xuanwu is the .......place they must pass through."

"Who in the military has supported us so far?" This is what Xiao Zheng is most concerned about.

"The people on our side must have seen Brother Xian a few days ago, but Li Jing in the army would rather go to fight against the Turks than help me, in vain I saved his life back then," Li Shimin said hatefully.

"What about General Qin Qiong, he is now in control of the defense of Chang'an City, with the help of General Qin, our chances of success will be much greater."

Li Shimin said helplessly: "I have looked for General Qin several times, General Qin is just loyal to my Tang Dynasty, although he is more inclined to me, but he doesn't want to help any party, General Qin has a life-saving grace for my Li family, even if I don't help me, I can't do anything."

"Your Highness doesn't need to worry, as long as you don't want to harm us, you are all friends. As for General Qin, I think His Royal Highness will fight for it again, and General Qin will impress with righteousness. At this time, Your Highness don't care about your face, for the sake of the common people in the world, even if you kneel in front of him and cry on your thighs, and use all the tricks you can think of, as long as General Qin is willing to help us."

After hearing this, Li Shimin gritted his teeth and said, "Okay, then I'll listen to you, brother Xian, and I'll go to General Qin right away." .......

Yan Qin You, revived the descendants of Yan Hui, and served as the left historian in Lantai to compile the history of the Tang Dynasty.

Early in the morning of the fourth day of the sixth month of the ninth year of Wude, just after leaving the house, I suddenly saw four soldiers holding the waist card of the Xuanwu Gate Zhonglang General and asked Mr. Yan to go to record the incident.

Yan Qin got into the car and followed the two to the woods behind the Xuanwu Gate Linhu Palace, and when he came in, he saw a young man who politely gave Mr. Yan a set of pen and ink utensils and said that something might happen in Xuanwu Gate today, but he just asked Mr. to come over and record it truthfully, and there was no malicious intent.

Out of the sensitivity of the historian, Yan Qinyou remained silent, and found a place with a good line of sight and sat down and waited quietly.

At this time, Li Shimin was kneeling in front of Li Yuan and told the prince Jiancheng and King Yuanji of Qi about the harem. Li Yuan's face was pale, trembling all over, and he pointed at Li Shimin, who was lying on the ground, and roared angrily: "It's okay if you say the truth, if you dare to frame the prince, I will punish you first today!" ”。

"What the child said is true, there is no treachery to his brother, if there is no truth, how can the child dare to talk nonsense in front of the saint, if Aya Jiang'er is killing him to avenge Wang Shichong and Dou Jiande, how can I have the face to see the thieves?" Li Shimin knew his father's temperament too well, first disrupted Li Yuan's mind and then moved out his military exploits, which immediately hooked Li Yuan's suspicions.

"Someone came, and it was rumored that the prince and the king of Qi would immediately enter the palace and play a match. Also, it is rumored that Pei Lian, Chen Shuda, and Xiao Yu have entered the palace, and I want to personally try this matter," Li Yuan said to the eunuch next to him.

"As for you, you can't go out without permission when you go back to the house to listen to the call," Li Yuan gritted his teeth and said to Li Shimin.

After Li Shimin walked out of the Xuanwu Gate, he looked back at the door deeply under the support of the guards, took a long breath, turned around and slowly walked towards ......the Qin Palace.
