Gao Fangping, the son of Captain Gao, traveled through time and fished Lin Chong out of the prison of the Ministry of Punishment ahead of time; Lin Chong escaped with the "death-row stand-in" Jin Chan and sneaked into Hebei with the remnants of 800 forbidden troops, training the world's first army "Beiweiying". Ten years later, when Bianjing fell, he showed his sword for the first time on the south bank of the Yellow River with the Wei army behind him - defeating 30,000 golden cavalry with 3,000 steps. From then on, "Lin Wudi" became famous across the two rivers.
