In Liu Yu's opinion, the power of the vassal kings was just surviving and could not be a big threat. The methods he used were a little more extreme, stabbing the prince of Hejian and detaining the king of Shu. Han Sheng felt that Han Sheng could not understand these things. Perhaps Liu Yu was so smooth and became frivolous.

Liu Yu did not pay much attention to the power of the Shu King and the vassal kings behind him. After all, the three most powerful vassal kings, King Huai, King Ding and King Jing, have been cut off. In his opinion, the remaining few franchises are just working hard to preserve the fiefdom and cannot cause any major turmoil.

But when Han Sheng mentioned King Su Zhe of Chu, Liu Yu was still instinctively careful. In the eyes of others, the King of Chu was just a prince of the late emperor, but in Liu Yu's opinion, he was the successor appointed by the late emperor and was a big concern.

"Brother Han, do you have any news about the whereabouts of King Chu?"

Han Sheng shook his head and said, "I don't know the specific whereabouts, but I know that he has collusion with the vassal kings."

As the former leader of the royal secret service, Han Sheng should have a secret investigation channel after handing over power to Liu Yu. Some people continued to serve Han Sheng like informants. Although Yang Lie arranged the intelligence network well, Liu Yu knew that the most important part of the imperial intelligence acquisition is missing.

Han Sheng's power cultivation for more than ten or twenty years can be said to have brought together the world's intelligence.

"Brother Han goes back to Chang'an from afar, go back to the mansion to rest first." Seeing that Han Sheng had nothing else more important, Liu Yu said, "Today I will marry the 14th Princess, and I will take Yi'er and Ting'er to the mansion alone to visit him!"

Han Sheng nodded. Although he missed his granddaughter, he was not as eager to see him. He still wanted to persuade Liu Yu to stop. Liu Yu said this, which was equivalent to not listening to advice. He wanted to use his own way to solve the problem of the imperial court's reduction of the vassal.

Liu Yu personally sent Han Sheng back to the house, and then calculated the time, and it was almost time for the wedding to be welcomed. If he did not show up at this time, the marriage would be in trouble. Liu Yu did not go home, so he went directly to the Ministry of Rites, and the car that was picking up the bride was there.

At dusk at sunset on April 19th, while Liu Yu was picking up his bride, the northern border troops also began to march northward to conquer.

Because I already have enough understanding of the border army, the tactic adopted by the frontier commander Min Shaoqing is to directly send troops to attack the old city outside the frontier.

The old city outside the border, which is the first time when the Central Plains dynasty flourished and the northern grasslands were weak, the Central Plains built on the grasslands. These cities were basically abandoned after the prosperity of the Turks. However, because the city walls were still there, as long as the city was captured and the army stationed there, they could use this as a means of relying on it. The encounters of the grasslands were transformed into offensive and defensive battles.

The people in the grassland are good at riding horses to fight encounters, and the imperial army is more suitable for defending. The border troops have always used defending the border as the basis for war over the years.

The army attacked, with the city as its base, and could attack and retreat or defend, which could reduce the advantages of the Turkic cavalry to the lowest level. When Min Shaoqing proposed this strategy, he was recognized by the emperor.

Min Shaoqing divided the army into six routes, ranging from 10,000 to 30,000 troops to 30,000 troops, echoing front and back support, with great momentum, so that the Turkic cavalry did not dare to disturb them and retreated again and again. In the early stage of sending troops, the imperial army was quite smooth.

All the tactics of the border army failed to pass Liu Yu, and Liu Yu was also notified afterwards.

Liu Yu knew that with Min Shaoqing's prudence, it was not uncommon to think of such a tactic. If it were him, he would not have taken the step by step, but instead used a more direct method. In his opinion, the tactics were good, but he couldn't think of what would be if the court army was trapped in an isolated city outside the border without help.

Unless Min Shaoqing can ensure that the six armies are continuous, they can adapt to the harsh climatic conditions of the grassland.

The Turks fought at home and had a high winning rate.

It was not the first time that Liu Yu, who welcomed the princess to get married, was already familiar with the etiquette of getting married and was familiar with what he did. However, this time he had an extra mother-in-law than when he married Xu Xuanzhu last time.

It was said to be a visit, but it was just a cup of tea from afar.

Qi'er's mother, Meiren, has a special identity. She is the concubine of the late emperor and cannot be easily shown to others. This is related to the royal face. Liu Yu respected the tea and the young wife could take her home. Qi'er was wearing a black dress with a black veil on her head, and was carried by a female official. She was very restrained and was carried on the car.

Liu Yu was about to go out to get on the horse, but his head was poked out of the house. When he saw Liu Yu, he stuck out his tongue and retracted his head. It was Wu Shuo who was reluctant to let Qi'er get married. Wu Shuo cried on his face, probably because he felt that his good sisters would become passers-by in the future and he was reluctant to let him go.

The princess got on the car and the groom got on the horse, and sent the "neighborhood" she found temporarily, and she could go home with a glorious charm.

Liu Yu originally thought that there would be no trouble before he saw those troublemakers when he got home, but who knew that there was an accident on the road. The axle of the car that was picking up the bride was broken. The whole car collapsed. If it weren't for the full car and the car was convertible, Qier would have been injured.

Liu Yu jumped off the horse and checked, and the axle was tampered with someone. The axle was the royal axle. After inspection in advance, there would be such a big mistake, which really made Liu Yu unable to imagine. Thinking of the series of mysterious things that happened in Chang'an City before, Liu Yu thought that this matter might be related to the assassination of the Uighur envoys and the people who robbed the prison. But he couldn't understand what the benefits of sawing off the axle. If the target was him, the assassin should have appeared long ago.

The veil on Qi'er's head fell off, and he looked at Liu Yu and the Imperial Guard beside him with a blank look. Liu Yu directly picked her up from the ground, because Liu Yu knew that the newly married woman could not touch the ground before entering the man's house. Liu Yu directly carried the person on his horse, and then he jumped up, hugged Qi'er's waist, and lifted the reins.

"This matter will be put on hold for the time being, and I will check it in detail later!" Liu Yu ordered.

On the side of the vanguard General's Mansion, all the etiquette of the princess getting married to the new emperor's marriage has been prepared, and we cannot delay time on the road.

The bride-welcoming convoy continued to set off. When the front general's mansion arrived at the gate of the vanguard General's mansion, you could see the bright lights from afar. Guests led by Su Yan were looking forward to it. When Liu Yu's horse was about to arrive at the door, Liu Yu was also preparing to dismount and take the bride home. At this time, a sudden "coax!" exploded. A house dozens of meters away from the front door of the mansion was blown up and bricks and stones flew everywhere.

"There are assassins!"

I don’t know who called out, but the Imperial Guard hurriedly protected the new emperor. Unfortunately, the assassin was not seen, and the explosions followed were endless.

The front general's mansion is the center of the circle, and the area around the area dozens of meters to several miles away is all the targets of attack. It may be because the guards around the front general's mansion are closely guarded and the assassins cannot pile up explosives, but even so, the entire front general's mansion seems to be in a shaky state.

Terror attack? Liu Yu held Qi'er trembling, and while using his hands to help Qi'er block his ears, checking the surrounding environment to prevent the assassin from suddenly jumping out. Fortunately, the wedding only had an explosion as a "congratulations" and there was no trace of the assassin. After more than a dozen explosions, the explosion stopped and the Imperial Guard went to the surrounding places where the bombed were viewed, and no one was left. It seemed that the mysterious man who created the explosion had prepared the retreat route in advance.

Just as the guests were still in shock, thinking that the matter had come to an end, a four-horse carriage suddenly rushed towards the Forward General's Mansion from a distance. The night was confused and could only see the carriage with a tall carriage and a skilled driver. Liu Yu was shocked. Isn't the carriage full of gunpowder?

"Stop!"

The soldiers of the Imperial Army who were approaching wanted to stop the carriage with weapons. This was obviously unlikely. The carriage rushed towards the guests without any obstacles. At this time, Liu Yu was still very calm. Amid the noise, he raised his right hand. Many Imperial Army soldiers and guards who had gone to war with Liu Yu understood what Liu Yu meant, and all lifted the muzzle of the musket at the carriage. When Liu Yu dropped his hand, a row of bullets had been shot out, all shot on the horses.

Between the calcium carbide sparks, the four horses fell forward almost at the same time, and the coachman fell directly from the carriage and died. The carriage suddenly emitted a huge fire, and the flames burst into the sky, sweeping the four horses, the coachman and the Imperial Guards, who had no time to dodge, into the huge fire, and pieces of broken wood flew everywhere, and also injured many people.

Fortunately, Liu Yu had already held Qi'er and found a bunker, and there were Royal Guardian soldiers on the Xinhuang as flesh shields, so Liu Yu, Qi'er and Su Yan were not injured.

The Royal Guard soldiers who reacted came forward to investigate, leaving no clues except for the broken limbs and arms.

"Escort the emperor into the door!" Liu Yu saw that the crowd was a little slow and ordered.

The Imperial Army quickly escorted Su Yan into the door of the vanguard General's Mansion, and Liu Yu also carried Qi'er into the door. At this time, the guests inside the door almost hid under the table. When they heard the sound, they had no idea what was going on outside.

Yuan Bolang appeared in front of Liu Yu with a look of panic on his face, and did not forget to accuse him: "Marquis Wuyi, you must explain to the emperor!"

"Bad!" Liu Yu cursed, "I want to know who did it!"

Liu Yu captured all the left and right commanders of the Imperial Army and ordered: "Go out of the city immediately and transfer soldiers from the Dongshui Daying into the city. The city gate will not be opened for the time being. The Imperial Army Unicom Defense Department Office, Jingzhao Mansion, and the whole city will search for assassins!"

Liu Yu knew that it would be of no benefit to say anything more at this time, so he had to use the simplest and most rude way to close the door of Chang'an City and thoroughly clean the Chang'an City.

The entire vanguard General's Mansion was in a panic. The Royal Guard General's Mansion was the center, searching everywhere. Before the matter was found, the imperial carriage did not dare to return to the palace. It was originally a great day for Liu Yu to get married, but was disturbed by this sudden change. No one would continue to focus on the unfinished wedding.

At night, the city gates were already in a lockdown, and checkpoints were set up on the road, and troops were mobilized on the road, and Chang'an City seemed very uneasy. (To be continued, please search for Astronomy, novels are better, updated and faster!
