Introduction to the Alone Savior: In the battle of Xinye, Liu Bei defeated Cao Cao with a small number and a large number. Cao Cao led an army of 500,000 to take revenge. Liu Bei's three thousand troops walked to Dangyang County and were suddenly intercepted by Cao's soldiers. They fought until dawn and escaped from Cao's pursuit. Zhao Yun, who was guarding Liu Bei's family, discovered that Liu Bei was missing and separated Mrs. Mi, mother and son. They hurriedly gathered thirty soldiers. He rode on horseback and fought his way back to the rebel army to look for him. Under the guidance of a sister-in-law, Zhao Yun found Mrs. Mi and her son by a dry well behind a broken wall. Mrs. Mi said: "Seeing that General Adou is saved,...I will die without regret!" After saying this, she jumped into the well and died while Zhao Yun was not paying attention. At this time, Cao's soldiers came to kill him. Zhao Yun tearfully pushed down the earthen wall and buried his wife. He hurriedly picked up Adou and rushed out. General Cao came and fought for three rounds, but was killed by Zhao Yun. Not far away, he encountered Cao General Zhang He again. After fighting for more than ten rounds, Zhao Yun seized the road and ran away. Unexpectedly, he and his horse fell into a trap. Zhang He drew his spear to stab him. Suddenly, Zhao Yun's horse jumped out of the trap. Zhang He was so frightened that he backed away. Zhao Yun fought with all the generals with might and valor. Cao Cao, who was watching the battle on the mountain, saw that Zhao Yun was unstoppable and ordered that he must be captured alive. Zhao Yun took advantage of this opportunity to break out of the siege, killing 50 Cao generals in a row, and finally handed Adou to Liu Bei.
