its about a guy who is said ti be a trash because he was stack in the same low rank level for 4 to 5 years. then after ibtaining a plant that will aid his growth he advance to a second level. and things started to change there. he is different from other same rank as he has the power that skip rank. his family though he is trash and was adopted only because his father is not his real father. there is also a group of strong cultivator on the inner section which is both sister and become his gf. as the youngest sister his first gf and the oldest because of the drug. he also has a familiar which is an asuraa kind a powerful at that. i read it in wuxia but i cant seem to find it.
since the answer is already out i am gonna be the "unpleasant and unhelpful" guy and write this: You just described the majority of CN webnovels (minus the plant, familiar )
