He inherits a damaged system that summons Crusaders and extracts essence from magical beasts to upgrade troops. At Late Golden Core stage, he commands 200,000 Imperial City Guards and demonstrates caution and decisiveness. He immediately deals with disloyal generals like Fang Liang, sends personal guards to monitor the suspicious Anle Marquis Jun Tianxiao, and maintains control through the Blood Battle Sutra cultivation method.
