Traveling back in time to Liu Feng, starting with rescuing soldier Guan Yu.

Transmigrating to the Three Kingdoms period, he found himself as Liu Feng, Liu Bei's adopted son. Before him lay the battle report of Guan Yu's awe-inspiring victory, his flooding of the seven armies—a death knell in Liu Feng's eyes! Liu Feng rallied his troops, marched from Shangyong, and went to rescue Guan Yu. ...If the Shu Han group hadn't suffered fatal losses when betrayed by Eastern Wu, would Liu Bei have still launched a campaign against Wu, resulting in his crushing defeat at Yiling? If the Prime Minister hadn't sent the boastful Ma Su to guard Jieting during his expedition to Qishan, would Zhuge Liang's fate have been better? If the Liu family emperor had returned to Chang'an with immense political prestige, would the dream of rebuilding the Han dynasty three times have been just a pipe dream? Everything changed when he rescued the Martial Saint from the siege of tens of thousands of Cao Cao's elite troops on the Jingzhou battlefield!
