This es an excellent piece of work. The characters are funny, well-developed. The OPness of the MC is not a let down as in many other novels. It is quite interesting to see MC think and work even though he has knowledge of many things.Note to author - You can try to elaborate more about on the ingredients and processes of making the equipment and pills. It will add more depth to the story. You can also add some background on the way some rare ingredient and materials are obtained. And if possible, please amke a glossary of power levels, world/realm names, raking of pills/weapons.
