Meng Hao merged all 123 Merdians into his fleshly body
Meng Hao merged 122 Merdians into his Eternal Stratum Merdian making it 122 times more powerful so he could make his 123 merdian
Meng Hao merged all 123 Merdians into his Blood Demon Grand Magic making it even more powerful than when even Blood Demon himself could do at Meng Haos level.
