Facing Yu Xing's approach, Liu Quan's heart became more and more frightened. When his attempt to survive through Yu Xing's mother failed, he put his only hope in the direction of Lin'an. It's just that the person he sent to lobby replied that Jia Rudao's door was difficult to enter and his face was ugly. According to the people in Jia's mansion who were secretly bought, Jia Rudao put it away and ignored it as soon as he saw that it was a letter from Luzhou. Just when this last life-saving straw also floated away, the news came that the famous general Gundam was also imprisoned for planning the law, which made Liu Quan even more panicked and couldn't sleep all day and night. Pinch your fingers and calculate, since Jia Rudao took control of the government, more than a dozen front-line generals in the Song army have been punished, some of them have been dismissed from their official positions, and they have been imprisoned for punishment, even after the death of Xiang Shibi and Cao Shixiong, they still sent cool officials to torture their families.

"There is no place to stay here, there is a place to stay here." Liu Quan is by no means a person who sits and waits for death, let alone watching the loss of glory and wealth. He now completely understands that whether it is Jia Rudao, Lu Wende or Yu Xing, they all want to put him to death and hurry up. Seeing that the way to live in the Great Song Dynasty was extinct, he did not hesitate to send a messenger to the Mongolian army. At this time, the people in charge of the military in central Sichuan were Niu Ling and the Mongolian general Baijianu, who returned to Sichuan, and Liu Heima, who was defeated from Chengdu and retreated to Jianzhou, was in charge of the people. The generals of the Mongolian army, such as Niu Ling and Baijianu, did not believe that Liu Quan surrendered sincerely, only Liu Heima believed that the Southern Song Dynasty court was rotten, and the important ministers of the court formed a party to exclude dissidents, and specialized in internal strife, and Liu Quan was forced to surrender very credible. For this reason, Liu Hei Ma pushed against public opinion, and while sending people to report to Kublai Khan, he sent his son Liu Yuanzhen to lead the army to Luzhou Shenjian City to meet Liu Quan.

Liu Yuanzhen's arrival made Liu Quan overjoyed, he personally went out of the city to welcome the Mongolian army into the city, and summoned his subordinate officials to gather in the official palace to discuss matters. Liu Cheng first denounced the mediocrity of the Great Song Dynasty and the corruption and incompetence of hundreds of officials in the court, and then scolded Jia Nidao, Lu Wende, and Yu Xing for framing Zhongliang, and the front-line soldiers shed blood, sweat and tears, saying that they were like a white lotus. This performance aroused a strong resonance among the subordinate officials, and for a while they forgot that Liu Quan's corruption and abuse of power were not under Yu Xing. "Good birds choose trees to perch", Liu Cheng saw that the crowd was excited, so he let the subordinate officials choose, agreed to descend to the east hall of the station, and disagreed with the west hall, for a time most of the people stood in the east hall. A few people hesitated for a while, but after turning their heads to look at the sword and axe hands around them, they all stood in the east hall, and only a pusher named Xu Biao stood in the west hall.

Liu Cheng first persuaded Yan Yuese, but Xu Biao was still unmoved. Liu Quan's eyes rolled, and he asked Xu Biao to write a table of demotion but was sternly refused. Annoyed, Liu Cheng asked the knife and axe hand to push Xu Biao out and behead him, and ordered the soldiers to kill more than ten members of his family. It's just that he searched and searched, but he didn't see Xu Biao's youngest son, tortured his neighbors, and only knew that he was taken to western Sichuan a long time ago. When Ouyang Xuan passed by Shenhip City more than a year ago, he had a long talk with Liu Cheng, and Ouyang Xuan had a deep understanding of him on this occasion, knowing that he was by no means a fellow traveler of the Thunderbolt Army, which was also the reason why he refused to sell firearms to Liu Cheng and lend a helping hand. It was also after this time that Ouyang Xuan knew that according to the trajectory of history, Liu Cheng would most likely surrender to Mongolia, and Xu Tuiguan would also be destroyed by Liu Cheng because of his opposition to Mongolia. Therefore, he quietly sent someone to persuade Xu Biao and took his young child to Chongqing Mansion. The reason why Ouyang Xuan went to great lengths to do this was not because Xu Biao was a foolish and loyal to the corrupt court, but because of his firm determination to resist Mongolia. For such an anti-Mongolian righteous man, the Thunderbolt army is obliged to leave a trace of blood and bones for him.

Liu Cheng led 300,000 households in 15 prefectures (military and prison) of Tongchuan Fulu to surrender to Mongolia, which made the situation in Sichuan very bad and the Southern Song Dynasty and the government and the opposition in an uproar. Even the mediocre Song Lizong knew that the big thing was not good, and urgently ordered Jia to "take all measures". Jia Rudao, who was addicted to enjoyment all day long, could come up with a foolproof strategy, but it was just to order Yu Xing to lead the army to suppress it, and ordered Lu Wende to prepare to aid Shu. Liu Quan's sudden rebellion made Yu Xing confused, he knew that Liu Cheng was by no means a good type, but he didn't expect him to flip the table. If he knew that Liu Cheng would surrender to Mongolia, Yu Xing would not be so aggressive, but would first cut his military power, and then slowly put him to death. It's just that it's useless to regret it now, Yu Xing had to order the Song army of the whole Sichuan to attack the states and counties of Tongchuan Fulu, and he led the army to take Luzhou Shenbutt City.

The Song and Mongolian armies maintained a balance of power in central Sichuan, and as soon as Liu Cheng surrendered, the balance of power was greatly tilted in favor of the Mongol army. Yu Xing wanted to defeat Liu Quan, and the Mongol armies in central and eastern Sichuan who confronted him naturally would not sit idly by, and they also sent troops to contain them, and for a time Diaoyu City, Dehan City and other places were attacked by the Mongol army. Under the offensive of the Mongol army, the Song army of all departments was tired of defense and did not send much military strength to accompany Yu Xing to conquer Liu Quan. However, Liu Quan's surrender was very sudden, which left him with only a few Mongol cavalry support, and it took a long time for the reinforcements led by Niu Xuan to reach Shenjian City. This made the battle of Shenhip City a duel between Liu Cheng and Yu Xing.

After Liu Cheng surrendered to Mongolia, Chongqing Mansion received an order from the Sichuan Preparation Division to send troops. Yu Xing knew that the Thunderbolt Army might ignore the order or find an excuse to delay, so he wrote a handwritten letter to Ouyang Xuan with a shy face. In the letter, he claimed that he had asked the imperial court to appoint Ouyang Xuan as the envoy of the western Sichuan town, but he did not mention the ban on the merchant ships of the Nanyang Company. It is said that Yu Xing even banned the merchant ships in Banzhou, which really annoyed Yang Wen. In this attack on Luzhou, the nearest Banzhou did not send people to participate in the war, you must know that in the past, once the imperial court was called, the Banzhou army would actively participate in the war. More than ten years ago, Yang Wen also sent 5,000 Banzhou soldiers to accompany Yu Xing to Diao and Yanzhou, and broke the invading Mongolian army. To say that Yang Wen's refusal to send troops this time is also very reasonable, that is, the Ukrainian barbarian soldiers in the direction of Dali have already deployed troops on the border of Miaojiang, and the Banzhou army wants to resist the invasion of the Mongolian army from Dongchuan County.

Resisting Mongolia is the purpose of the Thunderbolt Army, and Ouyang Xuan will never shirk because of a personal grudge with Yu Xing. It is one thing to rot the court, but it is another to save the suffering people. The Thunderbolt army not only had to defeat Liu Chuan and recapture Tongchuan Road and Shenjian City, but also defeated the Mongol army of Niulu and Baijianu in Sichuan in one fell swoop. It's just that Shenjian City is thousands of miles away from Chongqing Mansion, and even if there is a powerful naval army, the Thunderbolt Army can't venture deeper, otherwise it is very easy to be copied by the defenders of Xuzhou and other places under Liu Quan. Although the naval forces in these places are far inferior to the Thunderbolt naval forces, they can pose a serious threat to the logistical baggage fleet. The Thunderbolt Army will definitely attack Liu Quan, but it will not be led by Yu Xing, but will fight steadily according to its own plan.

According to the plan of the General Staff, the Thunderbolt Army will attack from the north, the center and the south to launch an attack on the Mongolian army and Liu's entire army. The northern route led by Huang Dagen led the second division, first eating Yang Wen'an's troops on the Mianshui front, and then directly advancing Mianzhou and Tongchuan Mansion, and Shi Zhongshu led the mobile battalion and special reconnaissance troops of the mountain brigade to infiltrate Longzhou and Shiquan Army through the mountain trails in Maozhou and Songzhou; The central route Cao Ergou led the first division to attack from Genting City, took Jianzhou, Zizhou, Puzhou and other places, and crossed Jiantandu to the east, captured Suining Fu, and established a defensive line along Fushui with the second division; The southern route led the third division and the main force of the naval army to take Xuzhou first, clear the road to the direction of Shenjian City, and after joining forces with the Banzhou army, the camera moved.
