Tian Hongsheng recovered quickly. In the battle of Shilongkou, the Japanese cavalry taught Tian Hongsheng, the company commander who was still a student, a profound lesson. Tian Hongsheng was anxious to report the battlefield situation in Shilongkou to the colonel. He had to cross a small town to find the regimental headquarters, which was the day when Xu visited the market town to collect horses. When Tian Hongsheng attacked Xu, he deliberately touched him, but failed, and Xu escaped.

With the help of the local beggar Hungxian, Tian Hong, Xu Huan and Hungxian crossed the town together and reached a safe place. Tian Hongsheng severely criticized Xu Huan and said that he would report the matter to the regimental headquarters. Tian Hongsheng found the regimental headquarters, and Xu Huan accepted the organizational review. Tian Hongsheng reported the situation of Shilongkou Campaign and the proposal of 7 15 Regiment to form cavalry units to the colonel, waiting for the colonel's arrangement.

The division approved the 7 15 regiment to ask for instructions and set out to form its own cavalry. Tian Hongsheng's classmate Yan Huanjing was appointed as the political commissar, and Zheng Xiaodong was appointed as the temporary battalion chief. Tian Hongsheng, who loved horses, rode horses and knew horses since childhood, gave great help to Yan Huanjing and Zheng Xiaodong. Tian Hongsheng was quickly appointed as the company commander of the fourth detachment of the 7 15 regiment by the head of the regiment. With Tian Hongsheng's efforts and training, a cavalry company with considerable scale and combat effectiveness was put into the battlefield.

Xu Huan was ordered to rebel against his father, and Tian Hongsheng followed the protection. As a result, he was discovered by the Japanese, and Xu Huan was arrested by the Japanese. Tian Hongsheng was saved, Xu covered his escape and was killed by Matsui. When they fled, Xu Huan was also shot and finally died. Adjutant Sun led his troops to surrender.

Soon, the cavalry company led by Tian Hongsheng and the cavalry team led by Toshi Utsumi Matsui fought a decisive battle at the foot of Daqingshan Mountain. Tian Hongsheng vowed to recover the blood debt owed by Toshi Utsumi Matsui in the Battle of Shilongkou. Under the cover of heavy snow, the next cavalry-to-cavalry duel began in Daqingshan. Tian Hongsheng and the cavalry waved combat knives and fought bravely. Tian Hongsheng and Toshi Utsumi Matsui fought one-on-one, and two rounds will be cut by Matsui. Matsui's cavalry was completely annihilated, and the Eighth Route Army cavalry was in full swing.
