This Demon King's Male Favorite Knows How to Cultivate Immortality Scientifically

(The cool demon king who loves to read story books@The warm-hearted guy who loves doing handicrafts) Lin Chen, who has been in puberty for a long time, has pimples on his face. He has a successful career but is not liked by girls. He thinks that he will probably die alone, but he does not want to be rescued by a big demon one day. He comes to a different world and becomes one of the big demon's... Male favorites...? He? Male favorite? Is there something wrong? Does the demon have such a strong taste? After seven days of soaking in the marrow washing pool, Emma was completely transformed. Emma was so handsome that even her own mother couldn't recognize her. It is rumored that the great demon is actually a toad spirit, extremely ugly and has a bad temper... Lin Chen: Haha, she can't be ugly as a female seductress! Sure enough, he found that the great demon who was disliked and feared by everyone was so beautiful that people couldn't take their eyes away. Ah, this... In fact, he doesn't mind having his yang harvested to replenish his yin, but I heard that serving the demon king risks death by explosion before he reaches the golden elixir realm! He doesn't want to die yet! Later, the demon king gave him a hand and made soup, and promised that he would not touch him until he got the golden elixir. Lin Chen was moved: The Queen is a kind-hearted person, and he should work hard to practice and get out of singlehood as soon as possible. All male favorites: Are you blind? (Ps: The female protagonist is not a toad, the male protagonist is scientifically cultivating immortality, he is ruthless and doesn't talk much, Shuang Jie! ^_^!)
