Voice dubbing is normal practice in Cdramas. Due to many reasons: actors having strong accents, scheduling conflict and no time, or because a professional voice actor does a better job of line delivery. In this drama, LYX is dubbing himself.
I love Fang Yilun! He ranks among my most favored actors. He’s incredible at playing characters caught between…
I like him a lot too but he surpassed himself here. I can't see any redemption for his character though, so many died as collateral damage to his schemes
