Well its all said in the title but i can explain more here. I read "World Seed" on royalroadl and really enjoyed the mix of magic and tech + the futuristic kind of thing. Also if there is anything like "The Gam3" on royalroal that will also be helpful ^_^. If there is(or are(which one is right...)) any recommendation can you please list them. Spoiler: Spoiler for World Seed(don't look if u haven't read it!!!!) well if there is a similar situation to world seed then that will be really helpful, like the virtual reality to normal reality kind of thing and the technomancy. I'm dying from boredom T_T Thanks!!

If you can stand reading mt for chinese some of Tjss, might do the trick, but i only read one so i can't guarantee there good.
Hmm... as for novels that have that mix of sci-fi and magic, try - Mahouka koukou no rettousei - Sword Art Online - Swallowed Star - Magic, mechanics, shuraba - Bu Sha (Kill no More) Slightly less relevant but might still be close enough to be interesting: - Ark the Legend - Knights & Magic
Haven't read World Seed, but you might like the Play to Live series. It starts off as mostly sci-fi but drifts more and more towards magic as the story goes on. It focuses a lot on characters and story rather than hardcore action though, so it depends on what you're after. Of course, there's a very good chance that it'll go into epic large scale interplanetary, interdenominational grade war towards the end if I'm not misreading my flags.
