@H i s o k a yup s** have one of process but it's only happen between husband and wife.its murim we can talking she can also absorbed his internal energy like time Mc absorb two stars energy

@Infinite_years nah bro in other manhwas, s** is the only way

@H i s o k a

thats for dual cultivation, absorbing someone elses energy is also possible, also, other manhua/manhwa artsits/writers are just overtly ho*** and incels, so they make intercourse required

theyre inherently sexist, thats why they choose such methods
