According to the erhu game network, in the game "Three Kingdoms Strategy Edition", total annihilation is the best tactic used by Zhang Fei to open up wasteland. Total annihilation is an instantaneous tactic, and it will not drag down the rhythm too much because there is no round preparation. Basically, the first few rounds of launching 1-2 times can solve the battle, and the output capacity is also very high, so it is Zhang Fei's first land reclamation tactic.
