I think chapter 291 reveals the origin of Wizard Lance. He is also a trasmigrated person from Earth, perhaps a gamer like Marvin. This is sth which I never saw in any other chinese novel, truly new.
What do you think?
Nightranger. Mindblowing theory
It is really not that surprising since the world he transmigrated in is the game itself. Maybe there's a power/entity behind this transmigrations?
Actually the author even write a book about Lance. I forgot the name may be you can find by googling author name.
