And another comment, I just did a quick calculation which is common as everyone would know this but if he has like above 1k wives each giving birth to at least 2 children then it would be like what an army of 2k toddlers and mid-schoolers with enough power to topple dimensions....I mean wow Author did ton of work on this but still...hot damn
By the way If anyone is new to webnovel and want to level up more quickly then download "Webnovel Lite" and sign into the account that you want to level up. Sign into both original WN app and the lite version with the same account. Complete the mission which gives you 15 Exp points and then go to the lite version and complete the old missions that we used to get(leave a review, leave a comment and reply to a comment.) Completing all of them will give you 30 exp points. Hope this helps you and work
