When the Yulin Army and the kidnappers were in the midst of a fierce battle, the head of Xuanxuanmen, Wu Zetian's henchman Yan Shuang led two thousand elite soldiers from the Xuanxuanmen headquarters to dispatch from the nest, Wu Zetian's nephew, Wu Zetian's half-brother Wu Yuanshuang's son, Wu Chengsi, the general of the Flying Cavalry Army, led 3,000 elite troops in the 20,000 Flying Cavalry Army, Wu Zetian's other nephew, Wu Zetian's half-brother Wu Yuanqing's son, and Wu Sansi, the general of the Right Guard, led 3,000 elite troops in the 10,000 Right Guards Army to quickly arrive from a nearby hiding place.

Xuanxuanmen has long been eyeing the kidnappers, and the kidnappers have been operating in Chang'an and the surrounding areas for nearly a month, if Xuanxuanmen is not aware of it, it is not an intelligence and espionage agency of the Tang Dynasty. The reason why Xuanxuanmen did not move when the battle occurred was because Wu Zetian ordered Yan Shuang, Wu Chenghe, and Wu Sansi to take advantage of this opportunity to wipe out the anti-Tang organization and the "Demon Gate" to which the kidnappers belonged.

After Wu Zetian got the information that the Demon Gate planned to kidnap Xuancheng and Princess Yiyang at the wedding of Xuancheng and Princess Yiyang, he was afraid that Li Zhi would be worried about the safety of his two daughters and cancel the wedding and reschedule it, thus losing a great opportunity to wipe out all the henchmen of the Demon Gate, so he did not tell Li Zhi and any of the Xuancheng and Princess Yiyang of this information, and issued a gag order to Xuanxuanmen.

Even the cronies of Wu Zetian's cronies, the henchmen Wu Chengsi and Wu Sansi also learned this information on the morning of the wedding of Xuancheng and Princess Yiyang, and were given a secret mission by Empress Wu, together with Yan Shuang, set up an ambush on the road to the marriage of the two princesses, when the Demon Gate kidnappers fought with the Yulin Army, Erwu and Yan Shuang did not move, hoping that the Demon Gate kidnappers would kill Princess Xuancheng and Princess Yiyang in anger, so as to remove the descendants of Queen Wang and Xiao Shufei who had been killed by Wu Zetian, borrow a knife to kill people, and cut the grass and roots.

Wu Zetian instructed these three cronies that if the Yulin Army could not defeat the Demon Gate kidnappers, or the Demon Gate kidnappers fled, these 8,000 elite soldiers would begin to collect the net and pursue the Demon Gate kidnappers; If the Yulin army captures the kidnappers of the Demon Gate, these 8,000 elite soldiers will not need to come forward and disperse quickly, so as not to let Wu Zetian use the knife of the Demon Gate to get rid of Princess Xuancheng and Princess Yiyang will be guessed by Li Zhi, causing Li Zhi's dissatisfaction; If the two princesses of Xuancheng and Yiyang were not killed in the melee, they were escorted to their new homes by the Yulin army, the Xuancheng Princess Mansion and the Yiyang Princess Mansion, and Yan Shuang would send his cronies to pretend to be from the Demon Gate, and assassinate the two princesses in the middle of the night after the married Yulin Army left.

Xuanxuanmen was the military intelligence and espionage agency of the Tang Dynasty, which was established when Li Shimin was the king of Qin, and the number of people has grown from dozens to thousands now. Its main tasks are threefold: first, to secretly supervise high-ranking generals, high-ranking officials, and local princes and kings to prevent anyone from plotting rebellion; second, espionage and counter-espionage against enemy and vassal states; Third, it is necessary to prevent the imperial families of the Sui Dynasty and the Northern and Southern Dynasties, which have perished, from restoring the country, and to strike at and eliminate the anti-Tang forces.

Xuanxuanmen has intelligence outlets in all states and counties of the Tang Dynasty, with 6,000 elite soldiers, more than 3,000 localities, and more than 2,000 headquarters in Chang'an. The soldiers of the Xuanxuanmen headquarters are very elite, all of them are martial arts masters, and they are directly commanded by the emperor in name, but Li Zhi suffers from headache and intermittent blurred vision.

Li Zhi's two most troublesome and annoying things, one is the management of the intelligence organs, and the other is the management of the cavalry elite troops, the flying cavalry army, and directly let Wu Zetian manage it on his behalf, and Wu Zetian will be in charge of military affairs on behalf of Li Zhi for a long time, and he will be bold and ambitious, and he will squeeze out all the people who are loyal to Li Zhi from key posts and replace them with his own cronies.

Li Zhi regretted losing his military power, but it was too late, and it was impossible for Wu Zetian to hand over the military power in his hands, so Li Zhi had to firmly grasp the left and right Yulin Army guarding the imperial city under his direct command and the Jinwu Guards guarding the imperial palace in his hands, and did not give power to Wu Zetian.

The supreme governor of Xuanxuanmen is called the chief manager, and the current chief is called "Yan Shuang", who is directly responsible for Empress Wu, and people only know that she is Wu Zetian's henchman, and no one knows her real name except Wu Zetian. In order not to startle the snake, Xuanxuanmen made a deployment half a month in advance, and transferred the most elite 200 people from the headquarters in more than 100 batches within ten days, and lived in dozens of inns along the way where Princess Xuancheng and Princess Yiyang got married.

According to the information they have, Xuanxuanmen speculated that the Demon Gate was likely to act on the way to the marriage of Princess Xuancheng and Yiyang, because there were many people watching the ceremony on the spot, and as long as it caused a mass riot, the actions of the officers and soldiers would be affected. The two hundred masters of Xuanxuanmen converged in the crowded crowd watching the marriage of Xuancheng and Princess Yiyang, and followed the wedding procession.

After the chaos caused by the kidnapping of Xuancheng and Princess Yiyang, the people of Xuanxuanmen lit fireworks to report the news, and Xuanxuanmen, the Flying Cavalry, and the elite troops of the Right Guard Army quickly arrived at the scene, and quickly blocked the road exit at the scene to collect the net on the Demon Gate.

After Xu Qing heroically saved the United States, he took away Xuancheng and Princess Yiyang, which was completely unexpected by Yan Shuang, Wu Chenghei, and Wu Sansi, Wu Zetian wanted to kill Xuancheng and Princess Yiyang, but she couldn't come to the light, she could only come to the dark, she didn't want to fall out with Li Zhi - although Li Zhi no longer had much real power, but he had prestige, Li Tang's royal family, nobles, nobles, ordinary soldiers, and ordinary people were all supporters of Li Zhi, and Li Zhi's energy could not be underestimated, Wu Zetian didn't want to force Li Zhigou to jump off the wall in a hurry, and carry out another action to abolish the queen.

This situation is not within Wu Zetian's instructions, Yan Shuang and Erwu did not dare to make their own opinions, after discussing, on the one hand, they sent people to report to Wu Zetian, on the other hand, they sent people to follow Xu Qing, Xuancheng and Princess Yiyang, and on the other hand, they carried out a quiet net collection operation against the people in the Demon Gate, changed the large-scale encirclement and annihilation to the whole city, and set up card checks at all intersections outside the city of Chang'an, making the illusion that Xuanxuanmen, the Flying Cavalry Army, and the Right Guard Army did not know that the people in the Demon Gate had kidnapped Xuancheng and Princess Yiyang, and they were not at the scene of the incident.

Xu Qing led his troops to enter the Chang'an branch of the Longmen Dart Bureau, two hours later, Zhao Tuozhi led the people to enter the Chang'an branch of Xianghe Qianzhuang separated by a wall from the Chang'an branch of the Longmen Dart Bureau, the weapon was of course hidden in the basement of the Chang'an branch of the Longmen Dart Bureau, gold, silver, and copper coins were placed in the money village for trading, and most of them were also hidden in the basement of the Chang'an branch of the Longmen Dart Bureau, not hidden in the money village, and the Chang'an branch of the Xianghe Money Village had an underground passage connected to the Chang'an branch of the Longmen Dart Bureau.

Xu Qing's subordinates were worried that Wu Zetian or Li Zhi would send someone to ask for Princess Xuancheng and Princess Yiyang, and they worried all night, and they waited for the bullet to load, but nothing happened. It wasn't until the next day that Xu Qing got the information that something big had happened in the palace.
