read up to chapter 41 and the book is worth reading, I really enjoyed it too much that it became one of my favorites in Webnovel now.
but please do not make MC gain some powers that are flashy while he is in TWD world, I'd say he can get physical related abilities like Mastery of different kinds of Weapons, Danger Sense, Unarmed Combat(hand-to-hand combat), and things like sprint(fast run), focused Strike, enhanced Perceptions/Senses/, Map, Big Inventory, . . .
AND NO FOR Magic/SuperSoldier physique/or some kind of Energy Blast/Bomb/Manipulation/Elemental Manipulation . . . . for now while he is in TWD, it would just ruin the the story in my Opinion.
continue the good work and please while you're at it try make chapters longer instead of writing many smoll chapters, pretty please? we like to read long chapters even if it means we get less chapters, I just don't like reading smoll chapters even if there are many of them, so please try make your chapters longer, start with 1000-1500, and you may be able to reach 2000 later on
