Yu Xing's army went to attack, besieged Luzhou, and attacked fiercely day and night, almost conquering the city. Mongolia sent Chengdu's strategic envoy Liu Yuanzhen to lead troops to reinforce Luzhou. Yu Xing fought with Yuanzhen, but the victory and defeat were not decided. However, Liu Zheng sent troops to attack Yu Xing, which caused Yu Xing to be attacked and was immediately defeated. Song Ting was dismissed because Yu Xing was jealous of his merits and provoked trouble and changed his official position and appointed Lu Wende as the envoy of Sichuan Xuanfu.

Lu Wende, whose courtesy name was Jingxiu, was from Huoqiu County, Anfeng Army on the West Road of Huainan. He was born as a civilian and was taken under Zhao Kui in his early years. In the first year of Jiaxi, Lu Wende led his army to rescue Anfeng as the commander of Chizhou, fought hard with Du Gao to defend the city and defeated the Mongolian army. The following year, he and Du Shu, Nie Bin and others led elite troops to set up ambush Mongolian troops at key points, and reported good news. When he guarded Zhenzhou, he was even "the people of Yizhen who relied on their lives." In March of the first year of Chunyou, the Song court ruled Luzhou as Lu Wende. Then, Lu Wende was promoted to Fuzhou Observation Envoy, Deputy Commander of the Cavaliers, and President of the Lianghuai Army went to fight in the army and horses, and also governed Qizhou, defending the border.

He once led a 3,000-man army to climb the Wohe River on a warship and rushed straight to Bianliang. The Mongolian army caught off guard and then retreated. In May of the fourth year of Chunyou, Mongolia besieged Shouchun Prefecture. Lv Wende led his troops to successfully rescue the siege. The Song court gave him a million yuan to reward the army. He also appointed Lv Wende as the commander of Huaixi, and also the governor of Haozhou. In the spring of Chunyou, a large number of Mongolian soldiers besieged Wuhekou. Lv Wende faced the unfavorable battle, burned the fortress, retreated to Haozhou to defend. Mongolia failed to capture Haozhou, and then retreated. Lv Wende took the opportunity to recover Wuhekou, and the Song court promoted him to third levels. Lv Wende was promoted to the commander of the guards and horse army. The following year, he defeated Mongolia's invasion against Huaixi and promoted him to the second-class.

With the deaths of Meng Gong, Du Gao, Yu Jie and others one after another, Lu Wende took on the backbone of the anti-Mongolian army and became the leader of the independent general. He relied on the "Black Charcoal Group" composed of his relatives and his hometown woodcutters and charcoal farmers to fight. His relatives and old friends, such as Lu Wenxin, Lu Wenfu, Lu Wenhuan, Lu Shikui, Lu Shilong, Lu Shidao, Lu Shimeng, Lu Shiwang, son-in-law Fan Wenhu, and fellow villager Xia Gui were all supported.

In the eleventh year of Chunyou, at the request of Li Zengbo, the commander of Jinghu, Lv Wende was transferred to his command and served as the umpire of Hubei and the governor of Xiazhou. Li Zengbo was ordered to pacify Sichuan, clean up the situation of Sichuan that was misled by the mediocre minister Yu Hui, and entrusted the military of Jinghu to Lv Wende. Zhao Yun then appointed President Lu Wende to Jiangling, Hanyang, Gui, Xia, Xiang, and Ying, and temporarily set up the department in the public security and support from all over the country.

At that time, Mongolia adopted a great detour strategy against the Song Dynasty, conquering Tubo and Dali, and encircled the southwestern border of the Song Dynasty. Therefore, the wars in the southwest gradually became tense. In July of the third year of Baoyou, the Song Dynasty was governed by Lv Wende, and controlled the five prefectures of Ding, Li, Chen, Yuan and Jing in western Hunan. Later, the Song Dynasty moved Lv Wende to the Changde Prefecture and Jingzhou to prevent Mongolia from leaking Jinghu from Yunnan and Guizhou.

In the autumn of the fifth year of Baoyou, the Song court learned that the Mongolian general Wuliang Hetai invaded the Luo Family Ghost Kingdom from Yunnan, so he transferred Lü Wende to the Bozhou area. Lü Wende did not confront Mongolia head-on in the southwest, but strengthened defense by building cities and appeaseing the indigenous people. He contacted the indigenous forces represented by the Yang family of Bozhou, built three cities such as Huangping, and appeased ethnic minorities in Guizhou. In the first month of the first year of Kaiqing, Zhao Yun issued an edict: "Lü Wende City Huangping went deep into the barbarian land, had a good time to pacify the officials, and made three transfers with the officials." In honor of this.

Lv Wende was transferred to the Sichuan front line again. In March of the first year of Kaiqing, he was appointed as the governor of Baokang Army. He established the deputy envoy and governor of Chongqing Prefecture. In April, he was also in charge of Sichuan's financial resources. He was not only responsible for Sichuan's military and political affairs, but also won the title of Jiedu. At this time, the Mongolian army, under the personal leadership of Mengge Khan, besieged Diaoyu City, Hezhou. Lv Wende's mission was to go up the Yangtze River and break the siege of Hezhou. The Mongolian army led by Nülin advanced along the command of Mongge, and stationed troops in Fuzhou, built a floating bridge on the Yangtze River, and prevented the reinforcements led by Lv Wende and Xiang Shibi and others from entering Shu.

After dozens of days of stalemate, in May, Lu Wende took advantage of the rising water and the wind to attack Duanfu Bridge, defeated the Mongolian army, opened the Shu Road, and entered Chongqing. After hearing this, Zhao Yun was very happy and wrote the poem: "Lu Wende led the way and attacked the Broken Bridge. The Shu Road was already open, and he is sincere to Shang." Lu Wende led more than a thousand warships along the Jialing River to reinforce Diaoyu City, breaking through the defense line of the Mongolian general Li Jin. Mengge sent Shi Tianze to fight, Shi Tianze divided the Mongolian army into two wings, "spreading across the river" on both sides of Heishi Gorge Dongshan, Hezhou, and the Mongolian navy "attacked along the current". Lu Wende failed and retreated to Chongqing. Although the main force of the Song army did not advance to Hezhou, it had a great impact on the defense of Hezhou. In July, Mengge died on the way to withdraw, and the war in Sichuan came to an end.

Although Mengge died, another army led by his brother Kublai Khan continued to attack Ezhou. In September of the first year of Kaiqing, Lu Wende went from Chongqing to assist Ezhou, defeated the Mongolian army's Baduer troops, and entered Ezhou at night to provide strong support. Kublai Khan retreated north and competed with Alibuge for the Khan throne, and the siege of Ezhou was lifted. The Song court issued an edict saying: "Lu Wende's reward for aiding Shu was not enough to repay the merits, and the merits of aiding Hubei are particularly significant. They are given one million and tens of hectares of fertile land." At this time, there was constant disputes within Mongolia, and there was no time to look south for a while. There was no major war on the border for several years.

At that time, Liu Zheng had great achievements, and Lu Wende was very jealous of him. Whenever Liu Zheng made suggestions, he would ignore them and not report the achievements of Liu Zheng's establishment. Because Yu Xing had a conflict with Liu Zheng, Lu Wende asked him to be the Sichuan commander to deal with Liu Zheng. Liu Zheng became more and more uneasy. In June of the second year of Jingding, the situation in Sichuan was very bad. Yu Xing sent troops to suppress Liu Zheng, but was defeated by Liu Zheng. After the defeat came, the Song court urgently sent Lu Wende to lead his army to attack Luzhou.

When Lu Wende entered Sichuan, Liu just happened to go to Mongolia. Lu Wende took advantage of the opportunity to attack and regain Luzhou. The court issued an edict to change it to Jiang'an Army, and awarded Lu Wende the prize. Because Lu Wende was flattered by him, Jia Sidao relied on him as a Gancheng and expelled most of the other generals. Jia Sidao used the name of accounting and border fees to frame the generals. Zhao Kui, Shi Yanzhi and others were not as good as the emperor. After the words "invasion, theft and concealment", they were all dismissed from office and claimed compensation.

Xiang Shibi had been impeached and demoted to Zhangzhou. At this time, he said that he eroded official salary, paid military expenses, and offended the superiors, and was detained to the Ministry of Justice. Fang Yuanshan, a subordinate of Mu, was very willing to flatter Jia Sidao and bullied Jia Shibi. Jia Shibi was unable to bear the humiliation and died. Jia Sidao was also jealous of Wang Jian and surrendered to Hezhou. Wang Jian died in anger. Zhao Yun was unaware of it and was blindly favored Jia Sidao. In the third year of Jingding, he gave him a million yuan in money and ordered him to build the first Fangyuan Garden, and then set up a family temple.

Jia Sidao became more domineering and acted as a blessing. Suddenly he received a report that the Mongolian governor Li Yu surrendered in Jingdong. Jia Sidao was overjoyed and asked him to

Zhao Yun ordered Li Yu to be the prince of Qi. Li Yu originally captured Haizhou and Lianshui army, captured four cities in a row, killed countless Song soldiers, Huai and Yang, and died. Since Mongolian Mengge died and Kublai Khan succeeded to the throne, Li Yu wanted to rebel and return to the south. He reported dozens of incidents in Mongolia, all of which were intimidating and coercing the Mongol master. Then he sent envoys to Kaiping, recalled his eldest son Li Xingjian, built Jinan, Yidu and other cities. He annihilated the Mongolian garrison troops and brought Jingdong to Song.

The Song Dynasty appointed him as king, and ordered him to be the governor of Ningwu Army, supervised the army and horses of Jingdong and Hebei Routes, and restored Li Quan's father, Li Quan, and changed the Lianshui Army to Andong Prefecture. Li Yan secretly contacted the Mongolian prime minister Wang Wentong and lured him into foreign aid. Wang Wentong also sent his son Wang Xu to Li Yantong. However, Kublai Khan noticed this matter, took Wang Wentong and was punished. Li Yan lost his aid and hurriedly led his troops into Zibo Prefecture.

Mongolia then ordered the king of the clan, Habichi, to lead all the troops to attack Li Yu, and the troops were very powerful. Because it was Prime Minister Shi Tianze going to war, all the troops were under his control. Shi Tianze went to Jinan and said to Habichi: "Li Yu has many tricks and elite troops, so he should not fight hard. Our army can have deep ditches and high bases to fight with him. Over time, he naturally became exhausted and did not worry about not being captured by me." Habichi said so, so he built a long encirclement under the city of Jinan, only to prevent invasion and attack, and not to go out to fight.

Li Yan went out of the city to challenge him many times, but no one responded to the battle. He attacked the enemy camp like a wall of iron and could not succeed at all. Li Yan then realized the pros and cons, and sent people to the Song court to beg for reinforcements. The Song Dynasty gave him 50,000 taels of silver to reward Li Yan's army, and also sent Xing Qingyang Mengyan to lead troops to help Li Yan. Qingyang Mengyan came to Shandong, fearing the strength of Mongolian troops, and dared not advance. Mongolia sent Shi Shu and Ah Mo each led his troops to Jinan. Li Yan led his troops out to rob the baggage, intercepted by the Mongolian army, killed and defeated, and fled back to the city.

Because Shi Tianze gathered a large number of reinforcements, he built a building on all sides and attacked the lonely city. Li Yu refused to guard day and night, waiting for the assistance, and gradually the food was gone, so he divided his troops to eat the people's family. Soon the people's grain was finished again, and everyone was hungry and even fed for people. Li Yu knew that the city was about to be destroyed, so he had to kill his wife and concubines, and he took a boat to Daming Lake. As soon as the main general left, the city was captured. The Mongolian soldiers searched Li Yu everywhere and chased him into the Daming Lake. Li Yu jumped into the water himself. However, the water was too shallow, so he did not drown. He was captured by the Mongolian soldiers and presented it to Shi Tianze. Shi Tianze took him one knife and two pieces and ordered the army to go in front of the army.

The next day, the Mongolian soldiers conquered the city to the east. Before they arrived in Yidu, the people in the city had already opened the door to welcome the surrender, and the Sanqi was occupied by Mongolia again. The Mongolian ordered Dong Wenbing to be the commander. Dong Wenbing was in the military camp. After receiving the order, he lighted cavalry and dressed in casual clothes. When he arrived in Yidu, he had entered the palace and did not set up a guard. Instead, he summoned Li Yu's old subordinates and ordered the court to urge him to the court. These people were naturally very happy. Before, Li Yu had two troops, Yi and Lian, with about 20,000 troops, and Habichi wanted to slaughter them all.

Dong Wenbing said: "They were coerced by Li Yu, how could they be killed? The emperor issued an edict to the south for the sake of peace. If they were to slaughter, they would probably not be exempted from punishment." Habichi then gave up and returned, leaving Dong Wenbing to stay in the custody. The Song Ting heard that Li Yu had been defeated and died, so he gave Li Yu the title of the chief magistrate and the temple title was given to Xianzhong.

Because the Song Dynasty first destroyed the alliance, Kublai Khan detained Hao Jing and accepted Li Yu, and was in vain. He decided to invade the south and appointed Ah Mo as the marshal of the southern capital, preparing to mobilize troops to move south.
