Review Detail of tortle in Magic System in a Parallel World

c'mon you know this is our little brother, it is definitely going to be good. It is similar to cultivation online with somewhat naive MC but without cultivation part. The world is an urban one with magic and artifacts, so it is refreshing to see such change. Mc is op just like yuan, he can learn magic easily because of his magic system. we can already see 3-4 harem members so idk which route it is going to take... innocent yuan type or smug su yang type xD. I am ok with both tbh, it will be great if he balances out things in this one. There's mystery involved as you may already know, our little brother likes to write stories of MCs with mysterious pasts. and it's already getting interesting so far. World settings looks great with magic elements, academic arc, his predecessor's enemies as well as swordmanship talent...our mc will have to go through alot in order to live somewhat comfortable life. Here Mc doesn't get his predecessor's memories too even after getting a system so that's refreshing too. He has his teacher/uhu uhu uk what I mean as well as a ghost? to be a guide so there's np. conclusion: If you like op mc with somewhat innocent nature and this is our little brother so there is not going to be a problem with story progression or world building...so do join the ride. If he doesn't decide to drop this, that is. Thank you, peace.
