Although Lich form is a Soul Form, it belongs to melee combat. Li Yao's Hunter skills are undoubtedly mastered to perfection, but there's still a gap in melee combat.
However, since players' skills are not yet mature at this stage, combined with his years of experience—although he was only a rogue for two years in his previous life, he fought constantly—it means that despite not being specialized in melee, he understands its techniques thoroughly.
Thus, in this life, his spiritual power is formidable, combined with his previous life's experience, he stands at the top in melee among players.
However, if we are talking about challenging higher levels remotely and even hunting world-level chiefs, then he still falls short.
But this is purely in Lich Death God form without the synergy with his own true form. If both can be separated, with his spiritual power, multitasking is effortless.
