Grand Completion Immortal Physique symbolizes invincibility; cultivators with it could even withstand attacks of an Immortal Emperor. Two cultivators with Grand Completion Immortal Physiques fighting together could trample over Burial Grounds and Ancestral Earths.
Immortal Physique Strikes
Immortal Physique Strikes (仙体击) are extremely rare and powerful techniques. Only Immortal Emperor with Immortal Physique at Grand Completion can create them. It is also speculated that the Physique Merit Law that Immortal Emperor used to reach Grand Completion must be self-made.
Some powerful cultivators could create an Immortal Physique Strike even without becoming an Immortal Emperor. For example, Evil Devourer Progenitor created the Charming Evil Strike, while Li Qiye created the Myriad World Soaring Immortal and Hell Suppression Godly Aegis.
