In SanGuoZhi, ZGL didn't beat CaoRen in BoWanPo. It was

Liu Bei who flamed the hill. ZGL didn't summon wind, which was only the author's creativity. ZGL wasn't the one who got free arrows from CaoCao on the boat. It was Sun Quan. It was ZhouYu and Sun Quan who defeated CaoCao on YangZi river. "Empty city trick"? Ironically it was applied by an unknown Wei officer on Wu's troops. The only battle that I would think of was the battle of HanZhong. Luo QuangZhong accredited all of these feats to ZGL to make him an invincible War god in his FICTION.
