Dou Jiande waved his army to the Central Plains, sent his personal general Master Li as a special envoy, and came to the Tang Army's camp in Bishan to persuade Li Shimin to withdraw from the army and return all the land owned by Zheng Guo. Otherwise, as soon as the army arrives, the jade will be burned!

Li Shimin saw that he was arrogant, so he ordered his subordinates to detain him.

After that, he summoned the generals to discuss countermeasures.

Du Ruhui, a member of the army in the book's office, said: "Dou Jiande can't sit still after all, His Royal Highness might as well take the strategy of besieging the city and sending reinforcements!" ”

Li Shimin asked, "Where can I send help?" ”

Du Ruhui replied decisively: "Wu Prison Pass!" ”

……

On the east of Luoyang, there is a Xiongguan called Tiger Prison Pass. It was named after King Mu of Zhou who had hunted tigers in this place. After Li Yuan established the Tang Dynasty, he changed the name of this place to Wujiaoguan because of the name of his grandfather Li Hu.

Wugao Pass is connected to Songyue in the south, the Yellow River in the north, and the mountains are staggered, which is a natural danger. This pass is easy to defend and difficult to attack, and there is a tendency that a husband is a pass and ten thousand people are not open.

If this pass is firmly guarded, the connection between Dou Jiande's army and Wang Shichong can be cut off.

At this time, Wujiaoguan was still under the control of Wang Shichong's nephew Wang Xingben. Therefore, sending troops to control the military prison has become a top priority.

And to garrison the Wujiao Pass, it is necessary to find a capable general who is good at defense.

When it comes to defending the city, no one is better at it than the veteran Qu Tutong.

So, Li Shimin summoned Qu Tutong and prepared to let him go to Wujiao Pass to defend.

didn't think about it, but Qu Tutong refused.

Li Shimin asked in surprise: "Old general, why is this?" ”

Qu Tutong stroked his beard and said: "At this time, Dai Guan, the deputy general of Wujiaoguan, is the old department of Li Mi of the Wagang Army, and this trip is none other than General Li Shixian. ”

Li Shimin's heart lit up and said: "The people of the world are not as thoughtful as the old general, please be worshiped by the people!" ”

Qu Tutong hurriedly helped: "We are all courtiers of the Tang Dynasty, and it is the duty of courtiers to recommend talents for the country." Your Highness has a reputation for ......"

On the second day, the Chinese army bought wine, and Li Shimin personally served Li Shixian.

He ordered Li Shiyun to lead 3,000 elites to quickly seize the Wujiao Pass.

After capturing the pass, stick to the place and make no mistakes.

After Li Shichang was killed, he quickly stepped up his horse and arrived at the Wujiao Pass at dawn the next day.

Wang Xingben, who was stationed here, originally led 5,000 men and horses to defend here, but as Luoyang fell into a crisis, the soldiers guarding the pass were disheartened and fled, and there were less than 2,000 men and horses at this time.

Dai Guan, the deputy general of the guard, worked with Li Shichang in the Wagang Army and had a good relationship.

Li Shiyun then asked someone to send a secret letter to Dai Guan, and made it clear to him the benefits.

Dai Zhou is a well-informed person, and he immediately sent a letter back to Li Shixian, expressing his willingness to do it at night, kill Wang Xingben, and then surrender the pass.

Wang Xing seemed to be aware of it, and after nightfall, taking advantage of the dark moon and high wind, he rode a fast horse and fled to Dou Jiande's camp.

After Li Shiyun won the pass, he ordered all the soldiers to carefully patrol the mountain, seal all the paths in the mountains, strengthen the pass, and send hundreds of crossbowmen to take turns day and night to guard the pass.

Li Shimin was very happy to learn that Li Shiyun had taken the Wujiao Pass, and he still ordered Dai Xuan to be the deputy general and stationed at the Wujiao Pass with Li Shiyun.
