suggest.since MC having a good memory, how about upgrade it as a perfect memory.make him to work as librarian in glory city. So he can be paid while he learning all of city's book.set his previous life as mathematician. After he knows all record of alchemy and inscription, make him to practice it with sciencetific aproach.
I wanted to ask if this will go the route of their being a massive time skip where the mc will reach the point of where cannon nie li died (though he’ll probaby a bit more powerful and more skilled and knowledgeable than the original) and then get transported back like the original adding up to two lives worth of experience? I know that sounds stupid but I wanted to ask anyway
