Li Yuan then asked Li Shimin's opinion, Li Shimin not only felt that what Li Yin said was reasonable, but also felt that Pei Lin and Li Jiancheng's words were also good, so he fell into a dilemma, and finally did not make a decision.

Seeing this, Li Yuan thought about it again and again, and finally adopted the opinions of Pei Lin and Li Jiancheng, and decided to let the army march eastward and compete with Li Mi for Chang'an.

Li Yin could only sigh helplessly, Liu Wenjing and Li Shimin are both strategic masters, but after all, they have their limitations, in the face of Li Mi, who is very strong at this time, who would have expected that Wang Shichong would be able to defend Luoyang City except Li Yin in this world?

On the 22nd day of the first month, Li Yuan, the king of Tang, took his son Li Jiancheng as the marshal of the Chinese army, and Li Shimin, the prince of Qin, as the marshal of the right army, led more than 100,000 soldiers and horses from all walks of life, under the banner of rescuing the eastern capital Luoyang, and went out of Tongguan in a mighty way, wanting to wait for the opportunity to move and compete with Li Mi for Luoyang.

Because Li Yin was clearly opposed to the eastward advance, Li Yuan was appointed Li Yin as the marshal of the road, and Li Yin was also happy to be idle about it, such a futile thing, even if Li Yuan asked him to bring troops with him, he was unwilling.

However, although Li Yuan did not let Li Yin go to attack Luoyang with Li Jiancheng and Li Shimin, he ordered to send Li Yin to lead his headquarters to Anyi City in Hedong County, thinking that Li Jiancheng and Li Shimin would be the backup.

On the 25th day of the first lunar month, Li Yin was ready to leave for Anyi, and on the night of the 24th, Li Yin, Song Zhengben, and Fu Ying met in the study.

Fu Ying reported to Li Yinyu at this time: "The palace maid who wanted to frame His Highness on the night of Chinese New Year's Eve, so that on the second day of being imprisoned, she bit her tongue and committed suicide in prison, and she had already been hastily buried, and this clue was broken.

However, the subordinates have recently found out that the palace maid was raised in the family of Zhao Chong, the attendant of the Criminal Department, and Zhao Chong's wife and the wife of Dou Wei, who joined the army in the Chengxiang Mansion, are both people of the Zheng clan in Xingyang, and according to the subordinates, before Chinese New Year's Eve, Dou Wei's wife and Zhao Chong's wife had more frequent contact than before, but they were afraid that they would not be able to get rid of it at this time. ”

Li Yin nodded, and expressed his appreciation to Fu Ying, the information he provided was not something that ordinary people could find out so quickly, it can be seen that Fu Ying is indeed a rare talent on the opposite side of intelligence collection.

"There is still information that needs to be reported to the Duke of Jin." Fu Ying said at this time: "After King Tang entered Chang'an, he accepted many concubines, one of whom has been more favored recently, and that person, like Dou Wei's wife and Zhao Chong's wife, also happens to be the daughter of the Zheng family in Xingyang. ”

After Li Yin heard this, he had already sketched out a plan for Dou Wei, Zhao Chong and the Xingyang Zheng family in his heart, through the conspiracy of the Chinese New Year's Eve night, he could get rid of him Li Yin, and he could also eradicate Xiao Wan'er, the most powerful woman in Li Yuan's current concubine family, paving the way for the daughter of the Zheng family in Xingyang to be further favored......

Li Yin also knew at this time that Li Yuan had dismissed him from the position of Jing Zhaoyin last year, transferred the garrison to Xinfeng, and also had Dou Jia's activities, so no matter whether this incident was led by the Dou family or not, since their Dou family was determined to oppose him, Li Yin no longer planned to tolerate it.

The tiger has not been powerful for a long time, and people will really think that it is a sick cat.

However, Li Yin has never liked to play some shoddy tricks like the Dou family, and if he wants to make a move, he must hit the opponent's vital point, so that the opponent has no power to fight back.

On the 25th day of the first lunar month, Li Yin said goodbye to his family, left Chang'an with Luo Shixin's hundreds of horsemen, and went to Hedong County to join his headquarters, but left Song Zhengben and Fu Ying, who were right-hand men.

For a flourishing family like the Dou family, the first thing to talk about is the interests of the family, and in the face of the interests of the family, everything has to stand aside.

And in these troubled times, as a big family, the first thing is how to survive and grow, and when the situation is unclear and I don't know who will finally win the world, these big families often leave a way back for themselves, and try to secretly make friends with all forces.

Because of Li Yuan's wife, the Dou family, the relationship between the Dou family and the Li family is very close, so after Li Yuan raised the army, Dou Rail, Dou Wei and others among the Dou family's children came to vote one after another.

But this does not mean that the Dou family bet all their bets on the Li family, like the previous Fufeng Taishou Dou Jin, it was only in the last resort that he decided to submit to the Li family.

And now another heavyweight of the Dou family, another brother of Li Yuan's wife Dou and Chen Guogong Dou Kang, now controls Lingwu County, Yanchuan County and other counties on the border of Guanzhong, but he still has not returned to Li Yuan, and is still in a wait-and-see posture.

Therefore, based on the filthy psychology of these big families, Li Yin can be very sure that the Dou family will definitely have dealings with other forces, even if there is no intention of colluding with other forces to betray the Li family, the exchange of letters should be indispensable, Li Yin asked Fu Ying to send spies to pay special attention to this matter before leaving for Hedong County.

Fu Ying mobilized a large number of capable generals for this purpose, secretly observed every move of the Dou Mansion, and obtained a lot of useful information, but it was not enough to deal a fatal blow to the Dou family.

Finally, half a month later, Fu Ying discovered a major piece of information, the Dou family had a slave, and after riding out of Chang'an City, he went to the northwest all the way, and did not stop after entering Fufeng County, and finally passed through the Longshan Mountains and entered the Longyou region.

Fu Ying immediately sniffed out the unusual smell from it, so he asked people to focus on following the slave, and learned that the slave finally entered the mansion of Chu Liang, the servant of the Yellow Gate of the Xue Ju Imperial Court, and stayed there for more than ten days before leaving Longyou.

When the slave left the Longshan Mountain Range and entered the inn in Fufeng County to rest, he was knocked unconscious by Fu Ying's stick, and Fu Ying searched the slave's package and body and got more than a dozen letters.

After Fu Ying selected the most important ones, put the rest of the letters back in their place, and then left quickly with the people.

After the slave woke up, he soon found that he had lost some letters, and he was immediately shocked, feeling that the guilt was too great, and he had the intention to escape, but he was afraid that the Dou family would be powerful in the gate, and he would soon be able to find himself out.

The lost letters were basically replies from important officials in Xue Ju's court, and one of them was written by Dou Wei himself to the crown prince Xue Rengao, but Xue Rengao did not accept the letter, and the servant had to keep it by his side, intending to bring it back the same way, but he didn't expect it to be gone.

After thinking about it again and again, the slave finally returned to the Dou Mansion with a fluke mentality, and did not say a word about the lost letters, only saying that the owner of the lost letters did not reply, and the letter to Xue Rengao was accepted, although the master of the Dou Mansion felt a little puzzled, but did not delve into it.
