Li Kaipeng told Ouyang Xuan in the letter that in the imperial court's commendation and reward for the Sichuan army's defeat of the Mongolian army in Jiading again, only Ouyang Xuan was promoted to the Yongkang Zhijun, and Yu Xing's father and son and Cao Zhizhou were not promoted, but only promoted in rank. The official system of the Southern Song Dynasty was very complicated, and the overall system was based on the separation of officials, positions, and dispatches. The rank of officials is divided into real officials and virtual officials, and virtual officials are literally understood as fictitious positions, which are only nominal official titles, but the actual situation has nothing to do with official names. Yu Xing and Cao Zhizhou were not promoted in their positions this time, and they were not even promoted in their virtual positions, but their grades were only increased by two levels. You must know that in Yu Xing's official document for reporting his merits, the ranking of his father and son's merits is still above Ouyang Xuan.

The reasons behind the imperial court's commendation are complex. On the one hand, Meng Ge personally led a large army to attack and plunder Shudi, and the situation in central Sichuan was critical, and a victory was urgently needed to boost morale. Although Meizhou was lost in the Battle of Jiading, after all, the Mongolian army was defeated, and he was still rewarded with promotion. Because of the loss of the city, he naturally could not be promoted to the position of Yu Xing's father and son, and could only choose the person who made the first contribution among Ouyang Xuan and Cao Zhizhou. To say that Cao Zhizhou also has connections with high-ranking officials in the court, but Yu Xing ranks his credit last, and Li Kaipeng has used silver money on many high-ranking officials in the imperial court, and there are even more people who support the Thunderbolt military merits. More importantly, in Chongqing, Lu Wende and Jinghu Jia Yidao also wrote letters for Ouyang Xuan's good words, and the discourse power of these two front-line leading ministers was extremely heavy, so Ouyang Xuan's promotion seemed logical.

Another reason that cannot be put on the table is the balancing art of the imperial court. A high-ranking official in the DPRK and China was drunk and quietly told Li Kaipeng that his promotion to Ouyang Xuan was also to contain Yu Xing and prevent his family from being the only one who did not listen to the dispatch of the imperial court. Since ancient times, due to its abundant natural resources and dangerous terrain, Sichuan has been very prone to separatist forces. In order to prevent this from happening, the imperial court used the "big and small" system in addition to the civil system, that is, to support the powerful deputy to balance the power of the main office. After Pu Zhizhi was appointed as the envoy of Sichuan and the governor of Chongqing, he soon promoted Yu Xing to the post of deputy envoy of Sichuan and governor of Jiading, which was to contain him. The imperial court also used and guarded against Yu Xing, hoping to rely on him to defend western Sichuan but did not want his family to dominate. In the case that Yazhou's strength is far inferior to Jiading's, the promotion of Ouyang Xuan to Yongkang's Zhijun can not only make him grateful to the imperial court, but also allow Jiading, Yongkang, and Yazhou to contain each other and form a check and balance against Yu Xing.

Of course, in Yu Xing's mouth, Ouyang Xuan's promotion to Yongkang Zhijun is another version entirely. In the letter he wrote to Ouyang Xuan, he first praised Ouyang Xuan greatly, and then attributed the credit to himself as soon as the conversation changed. It was precisely because of his discernment and strong recommendation that his strength even exceeded that of his son Yu Dazhong, which made the emperor reward Ouyang Xuan. He also believes that Ouyang Xuan is not ungrateful, and the people in Perak will also "drink water and don't forget to dig wells". Reading the letter, Ouyang Xuan had already guessed what Yu Xing was going to do. This Yu Xing's father and son are extremely greedy, and most of their interactions with the Thunderbolt Army are directed by Ji, and when they lower their stature, they all want to gain benefits from the Thunderbolt Army, and they have a strong purpose.

Sure enough, at the end of the letter, Yu Xing ordered the Thunderbolt army to send troops to attack the Mongols, but the tone was very gentle and even pleaded. It turned out that the official document that came with the imperial court rewarding his father and son was also the official document of Lu Wende ordering Jiading Mansion to send troops south to Chongqing Prefecture. Pu Xuezhi was dismissed from his post as envoy to Sichuan in March, and the supreme governor of Sichuan was succeeded by Lu Wende. At the same time as Pu Zezhi was dismissed, Lu Wende was appointed as the envoy of the Baokang Army, the deputy envoy of the Sichuan system and the governor of Chongqing, and in April, he was the chief of Sichuan's financial endowment. He not only commanded the military and political power of Sichuan, but also won the highest honor of the Song Dynasty military generals - the title of Jiedu Envoy. It was only due to the lag in information that the Thunderbolts received official news at this time. Yu Xing was afraid that when he led his army to Chongqing Mansion, the Mongolian army would take the opportunity to attack Jiading. Therefore, he hoped that the Thunderbolt army would send troops to attack in order to lead the Mongolian army in the direction of the capital.

At this time, the Mongol army, under the personal leadership of Möngke Khan, was besieging the Diaoyu City of Hezhou, and Lü Wende's task was to trace the Yangtze River and relieve the siege of Hezhou. At that time, the land and water armies led by Niu Ling were also ordered by Meng Ge to garrison Fuzhou and build a pontoon bridge over the Yangtze River to prevent the reinforcements led by Lu Wende and Xiang Shibi from entering Shu. After dozens of days of stalemate, Lu Wende took advantage of the rising water and favorable winds to break the pontoon bridge, repelled the new road, and opened the waterway into Chongqing. At that moment, he was ready to lead more than 1,000 warships up the Jialing River to reinforce Diaoyu City, so he ordered Luzhou, Xuzhou, and Jiading to send troops to attack the Mongols.

An army without faith is a rabble after all, and as the Thunderbolt army continues to grow, there is an urgent need for a common faith to unite people's hearts. The slogan put forward by Ouyang Xuan, "Expelling the Tartars and Strengthening China" was not only supported by the Perak Army, but also widely echoed outside the Perak Army's jurisdiction. It was the wish of every Song person to expel the Mongols from the Central Plains and restore the Chinese clothes, and a large number of loyal generals such as Yue Fei, Han Shizhong, Meng Hui, and Yu Jue fought bloodily and died for this. And the country is strong and prosperous, and the people can live a prosperous life, which is also the ultimate goal pursued by every person with lofty ideals for thousands of years. Yu Xing went to support the Diaoyu City war, which was obviously conducive to the anti-Mongolian cause, and the Perak army would fully support it.

As long as it is conducive to the cause of resisting Mongolia, Ouyang Xuan will support it. Ouyang Xuan told the messenger of Jiading Prefecture and asked him to tell Yu Xing that there would be a major flood in the Minjiang River in the next few days, so please prepare for disasters. When the flood receded, the Thunderbolts would attack the Mongols with all their might. The envoy was skeptical, but seeing Ouyang Xuan's burning words, he didn't seem to believe it anymore. This envoy has traveled back and forth to the Perak Army area many times, and he has long heard that Ouyang Xuan has an unpredictable prophet, so he immediately returned with a gift.

Different from the money and silver silk silk given to Yu Xing in the past, the gift to Jiading Mansion this time was 500 old-fashioned grenades. At present, the production capacity of new grenades in Dayi Arsenal has not yet reached expectations, and the battles of Guankouzhai and Jiangyuan City have consumed a lot, so that the inventory of new grenades in the Thunderbolt Army is very small. Fortunately, the production of the two old engineer factories in Qianjiazhai and Liuliba was normal, so the old-fashioned grenades that were originally deployed to the second-line troops were given to the Jiading army. Although this old-fashioned grenade is not as good as the new grenade, its performance still crushes the Mongolian army's earth-shattering thunder, which can be called a weapon to break the enemy in a water battle.

The joint military-political meeting decided that after the summer harvest was completed and preparations for the flood control army were made, the troops would attack the Mongolian army in two directions. According to the current progress, it only takes three days to harvest all the summer grain, and it will take another three days to transfer the personnel and materials in the low-lying areas to higher places, and the widow's cliff can be blasted. Since the formation of the dammed lake, the Perak Army has been carrying out small-scale blasting, draining excess water to prevent the levee from bursting prematurely. Before Huang Dagen returned to Chongqing Mansion to take up the post of chief of staff, he had ordered people to prepare an astonishing amount of explosive gunpowder, and also asked the people in the valley area of Weimao and Weimao to start transferring property and materials in advance. With just a blasting order, the monstrous flood formed by the dam failure of the dammed lake will rush along the valley of the two states of Maowei to Guan Kou Sai, and go straight down the Jinma River to the Daojiang, Pengshancheng, Meizhou, Jiading........
