Li Shimin couldn't think of any nobles who would help him, but Zhang Yunwen knew. Tang Jian, Qu Tutong, Yu Wenshi, Wen Yanbo, Liu Hongji and other high-ranking officials, under the friendship and money offensive of Zhang Yunwen and Changsun clan, agreed to Zhang Yunwen's approach and promoted fifty reconnaissance battalion soldiers into the palace.

Zhang Yunwen was sitting in the Zuiyun Building at this time, looking at the information in front of him with a frown.

The Youzhou Investigation Institute has lost contact with the General Investigation Institute. This made Zhang Yunwen feel a little worried.

According to the statute of the Investigation Institute, the Chang'an Investigation General Institute has to hand out a piece of information every Friday, but this information has a poem on it. The local investigation institutes that received this poem turned out a large pile of poems and songs, Han and Wei poems, and then found the next sentence and sent it back to the General Investigation Institute.

At this time, it is the busiest time for Zuiyun Building. There are dozens of roads across the country, and each one flies out of a pigeon, plus the pigeons that send information, it can be said that a flock of pigeons are flying all over the sky. Fortunately, Zhang Yunwen taught a dish of "braised pigeon" in Zuiyun Building, which made people doubt the use of these pigeons a lot.

However, the Youzhou Provincial Investigation Institute has not had pigeons since April.

Fortunately, Zhang Yunwen happened to be in Zuiyun Building on the fifth day of the fourth lunar month, and when he saw this situation, he directly asked Lin Ran to change a new set of codes, and at the same time all the personnel of the investigation institute in Youzhou were suspected, and the personnel of the investigation institute in any other place were not allowed to contact the Youzhou Investigation Institute.

"Du Sheng, is it Du Sheng?" Lin Ran asked with some confusion.

Zhang Yunwen's mind suddenly flashed a taciturn face, and he nodded: "Well, in March, Du Sheng asked to go to Youzhou, and I agreed!" And then in March, this happened. Youzhou Luo Yi is a border general close to the prince, this Du Sheng may have voted for the prince! ”

slapped his thigh, Zhang Yunwen said fiercely: "Damn, if Lao Tzu wasn't very busy in Chang'an, he would have slaughtered this kid in Youzhou!" ”

Lin Ran said on the side: "Do you want your subordinates to arrange for someone to go to Youzhou to kill the Youzhou Investigation Institute?" ”

Zhang Yunwen shook his head: "Now is a critical period, don't send people out of Chang'an." Moreover, this Youzhou is Luo Yi's territory, and we can't do it! By the way, from today onwards, this drunken cloud building will leave two guys to be responsible for collecting information, and all the rest will be given to me to go out and help watch the vicinity of King Qin's mansion. If something happens to the Qin Palace, we will die and will not be redeemed! ”

Similarly, Zhang Yunwen also closed the door of the natural residence and let those stewards return to the Qin Palace. And that Yang Chang, after Zhang Yunwen handed him a Mo knife, he also asked him to go to the Qin Palace, just in case of accidents.

Suddenly remembered his two elder brothers, the Xuanwumen incident came immediately, the two elder brothers are still in the barracks, if so, there is no credit at all, then the original promise to the Korean sisters is not in vain!

So Zhang Yunwen rode a fast horse, pulled Liu Yong and Liu Wu back from the barracks, and threw them directly beside Wei Chigong.

After the early dynasty, Li Yuan's inventory and cleaning of the harem made many concubines and palace maids smell an unusual smell. Many of these concubines and palace maids have accepted Li Jiancheng or Li Yuanji's property or benefits, so they have passed the news outside the palace.

Although the fifty scout battalion soldiers were many, it was impossible to cover everything. So, at ten o'clock in the twilight, the East Palace received the news that Li Shimin had told the truth in front of Li Yuan.

Li Jiancheng summoned Li Yuanji to discuss countermeasures as soon as possible.

After listening to Li Jiancheng's statement, Li Yuanji said: "The current situation is unclear, we should take care of the soldiers in the East Palace and the Qi Palace, and pretend that they are sick and do not go to the court, so as to observe the situation and make plans after it is clear!" ”

Li Jiancheng shook his head and said, "The army in the palace is already very well guarded, and it is difficult to find out the news. My fourth brother and I should go to the court to see and inquire about the news in person. Saying that, he paused, "Now, the Xuanwu Gate and the Chengtian Gate in the palace are all owned by me, if my father really listens to Li Shimin's words, then Gu will force my father to deal with Li Shimin in turn!" ”

Li Yuanji nodded approvingly.

"Okay, since the fourth brother agrees, then we'll go out now to find out the news!" So the two of them went out of the East Palace and visited the homes of important officials of the court one by one, and finally heard some news.

These news are nothing more than Li Shimin and Li Yuan's secret agent, Li Yuan will edict the two of them tomorrow! As for what Li Shimin and Li Yuan talked about, none of these ministers knew. Even Pei Lian, who was deeply favored by Li Yuan, didn't know.

The two of them returned to the East Palace in a huff, although they felt that something was faintly wrong with this matter, but they suffered from too little information, and their grasp of the situation was a little worse. I had to ambush the troops and wait for tomorrow to make a decision.

The East Palace did not move, and the Qin Wangfu sent Zhang Yunwen to lead twenty archers to occupy the Xuanwu Gate that night.

Late that night, Zhang Yunwen took twenty soldiers, wearing ironclad uniforms, swaggered to the outside of Chengtianmen, flashed the waist card of the East Palace, and said to the Chengtianmen guard: "I will wait for the order of the prince to assist General Chang to guard the Xuanwu Gate, and I hope the general will let him go!" ”

For outsiders like Zhang Yunwen, if you want to enter the palace, you must first pass through Chengtianmen. Behind the Chengtian Gate, there are Taiji Palace, Yeting and East Palace. To the north of Taiji Palace is the Xuanwu Gate.

The Chengtianmen guard glanced at Zhang Yunwen suspiciously: "Brother face is very good?" Why don't you come from the training gate? ”

Zhang Yunwen's face suddenly turned pale: "Hmph, you don't care about the affairs of the East Palace!" ”

The guard general was unmoved: "Lao Tzu also stayed in the East Palace, why haven't I seen you?" ”

Zhang Yunwen was suddenly surprised: "Oh, it turns out that I also work for the prince, disrespectful and disrespectful!" The younger brother really entered the East Palace when he recruited the Changlin Army, and later some of the brothers dispersed, but my brothers obeyed the prince's arrangement and stayed in the outside workshop. If something happens, come out and deal with it! ”

When the guard saw that Zhang Yunwen was right, he was immediately relieved: "Since you are the prince's person, let's go in!" ”

I only listened to the door "smack" open, and the gate of Chengtianmen opened a little.

Zhang Yunwen calmly entered the Taiji Palace with twenty people.

Passing through the Taiji Palace neatly, the guards on patrol also took the initiative to say hello. Those guards looked at the waist card of the East Palace on Zhang Yunwen's waist, and they were also enthusiastic about Zhang Yunwen.

When I came to the Xuanwu Gate, I saw that the towering city tower looked particularly hideous in the dark night, and the thick wooden gate also exuded a cold air.

Tomorrow, a lot of people will die here tomorrow!

Zhang Yunwen walked to the Xuanwu Gate and learned to meow. Hearing the sound of a cat's meow, Chang He looked down and saw more than 20 people standing below. So he asked, "Are you sent by His Royal Highness the Crown Prince to assist us in guarding the Xuanwu Gate?" ”

Zhang Yunwen said: "We came on the orders of His Royal Highness, and I hope that the general will open the city gate."

A moment later, the city gate opened, and Zhang Yunwen and twenty soldiers waited to go up to the city tower. Under the strange gaze of the guards of the city, he rested with his back against the city wall and his clothes.
