On the third day of the sixth month (July 1, 626 AD), Taiji Palace. Taishi Ling Fu Yi, who is proficient in astronomy and almanacs, reported to the Tang Emperor Li Yuanyu: "Last night, the Tai Bai Star appeared in the sky of the imperial capital Chang'an, this is a vision, I hope Your Majesty will be more vigilant." ”

As the son of heaven of the Tang Dynasty, Li Yuan also attached great importance to God's warning, and hurriedly asked: "What does this celestial phenomenon mean?" ”

Fu Yi replied: "The imperial capital is Chang'an, and Qin is also." Too platinum star, the master of killing. The appearance of the Tai Bai Star in the night sky of the imperial capital Chang'an is a sign that the King of Qin will possess the world through killing. ”

After listening to Fu Yi's answer, Tang Emperor Li Yuan's face suddenly turned gloomy and he became vigilant. He secretly said in his heart: "King Qin has the world through killing? So what will happen to the completion of the Tang Dynasty prince? What will happen to me? All of them were killed by him King Qin? Be a stepping stone for him to ascend to the throne? No, I will never allow such a thing to happen, absolutely not. Chang'an, the imperial capital, everything is still under my control, I have an army of five guards, I have an absolute advantage, I will never allow him to set off such a storm! ”

Soon, Fu Yi left the Taiji Palace, and the Tang Dynasty Prince Jiancheng walked into the Taiji Palace at the right time.

Emperor Li Yuan of the Tang Dynasty asked the crown prince: "Just now, Taishi ordered Fu Yi to report to me: Last night, the Tai Bai Star appeared in the sky of the imperial capital Chang'an, which is a sign that King Qin has the world through killing. What do you think about this? ”

Prince Jiancheng pondered for a moment and replied: "The words of the celestial phenomena are ethereal. Erchen thought it was not enough to believe it, but he had to be vigilant against Li Shimin, the king of Qin, after all, he had the left and right leading guards in the imperial capital Chang'an, and the right Xiaowei three guards. ”

Emperor Li Yuan sighed: "Yes, he has an army of three guards. It is precisely because he has the support of the Sanwei army that he has become the biggest threat to the stability of the entire imperial capital Chang'an. ”

When the crown prince heard Emperor Li Yuan say this, he bowed down and saluted: "For the stability of the imperial capital Chang'an, and for the sake of the Tang Society, Erchen proposed to quickly transfer the Sanwei army controlled by King Qin from the imperial capital Chang'an on the grounds of the urgency of the military situation on the front line. In this way, Li Shimin, the king of Qin, will no longer be a threat. Without the support of the army, the king of Qin should have the world, which is just a joke. ”

Emperor Li Yuan of the Tang Dynasty watched the completion of the Tang Dynasty with satisfaction, and showed a pleased smile. The Tang prince is becoming more and more satisfied, he has no threat to himself at all, and he is smart and wise, knows how to retreat, abides by the rules, and has been wise and clever recently, making his eyes shine again and again, and he is surprised. Li Yuan secretly said in his heart: "The Tang Dynasty has a prince like this, and I don't have to worry about it." ”

Li Yuan summoned Wang De, the chief eunuch of the eunuchs, and asked him to convey to Li Shimin, the king of Qin, that "the front line is tight, and the left and right leading guards are urgently recruited, and the right Xiaowei three guards are rushed to the front line." ”

After the edict was transmitted, Li Shimin, the king of Qin, sent guards to invite Li Xuan, the king of Yong'an, Gao Shilian, the secretary of the ministry, Chi Jingde, the general of the right Xiaowei, Cheng Yanjin, the general of the left army, Zhang Gongjin, the general of the right army, Zhang Liang, the Shaoqing of Honglu Temple, the eldest grandson Wuji, and Tang Jian, who were their henchmen in the imperial capital Chang'an, to come to discuss the matter.

Qin Wangfu, outside the study of Li Shimin, King of Qin. As soon as Li Xuan walked into the courtyard from the gate, he saw Tang Jian pacing back and forth in the courtyard outside the study, glancing at the gate from time to time, as if waiting for someone. Li Xuan walked up to him with a smile, patted him on the shoulder, and joked, "Why don't you go in?" Who are you waiting for? Which one is in the picture, tell me, I will ask the king of Qin to match it? ”

Seeing Li Xuan, Tang Jian was overjoyed. He pulled Li Xuan down to a remote corner and reported to Li Xuanyu in a low voice: "Soon after discussing a major event last time, Zhang Ping, the personal guard of King Qin, secretly left King Qin's mansion and went to the mansion of Feng Deyi, the right servant. I think it's suspicious. ”

Li Xuan fell into deep thought.

King Qin and himself have always suspected that by King Qin's side, there is the eyeliner built by the crown prince. This person has not been found. King Qin and himself both thought that maybe the crown prince's eyeliner did not exist. Now that King Qin's personal guard Zhang Ping is suspicious, could he be the one who was built by the crown prince? If he was the one who was built by the crown prince, what did he go to see Feng Deyi for? Feng Deyi is not the prince's person, he supports King Qin. As the confidant and strategist of Li Shimin, the right servant of the Tang Dynasty, Feng Deyi, was the king of Qin's own person, which was told to him by the king of Qin himself. Could it be that Zhang Ping was not the one who was built by the crown prince, but was ordered by the King of Qin to disguise himself and secretly contact the right servant to shoot Feng Deyi? However, Feng De Yi Gui is the right servant of the Tang Dynasty and has a noble status, will His Royal Highness the King of Qin send a guard who can only slash and kill to inform Feng De Yi of the major events of the Xuanwu Gate? Li Xuan felt that this was absolutely impossible. What is the relationship between Zhang Ping and Feng Deyi? This Zhang Ping is suspicious, so naturally he has to be on guard.

Li Xuan said to Tang Jian: "Zhang Ping, he is the personal guard of His Royal Highness the King of Qin, and the person whom His Royal Highness the King of Qin absolutely trusts, we have no evidence and can't touch him, but for him, we can't help but be vigilant." You pay close attention to Zhang Ping and Feng Deyi's every move, and see if they have any contact and contacts with the people in the Prince's East Palace. For a long time, King Qin and I suspected that His Royal Highness King Qin had the eyes of the crown prince by his side, but we didn't find this person, and I hope you can dig him up and get rid of him. It is too dangerous to have such a person by the side of His Royal Highness King Qin. ”

Tang Jian said in a low voice: "Please rest assured, King Yong'an, I will find this person as soon as possible." ”

Li Xuan said: "Well, the sooner the better. King Qin's big event is approaching, and we must not allow such a person to hide by His Royal Highness King Qin's side. ”

After that, Li Xuan and Tang Jian walked into the study of Li Shimin, the king of Qin.

In the study, Gao Shilian, Wei Chi Jingde, Cheng Yanjin, Zhang Gongjin, Zhang Liang, and the eldest grandson Wuji sat on the Huanghuali high-backed chairs on both sides of the head of Li Shimin, the king of Qin, with gloomy faces. Li Xuan and Tang Jian walked quickly to their seats and sat down. As soon as he raised his head, Li Xuan saw Zhang Ping standing behind Li Shimin, the king of Qin, and he couldn't help but stand up and said to Li Shimin, the king of Qin: "Please ask His Royal Highness the King of Qin to retreat left and right, and then discuss major matters." ”

Li Shimin, the king of Qin, said with a smile: "King Yong'an is too cautious. They are all old people who have followed me for many years, they have all gone through many tests, and they are all people I trust. They won't talk nonsense about our business. ”

Li Xuan pleaded again: "If the king is not careful, he will lose his trust in his ministers, and if the ministers are not careful, they will harm themselves. Now, we are still suspicious that His Royal Highness King Qin has the eyeliner built by the crown prince by his side. How can you not be extremely cautious and cautious every step of the way? I hope that His Royal Highness the King of Qin can listen to the advice of his ministers, retreat left and right, and then discuss major matters. ”

Li Shimin, the king of Qin, smiled helplessly, waved his hand, and motioned for Zhang Ping's guards and palace people to leave.
