This book has stretching unnecessary plots and dramas. As a cultivator even he didn't has cultivation in those lives his conscious and soul are strong. If he is willing, he can easily solve problems/missions in those worlds. He didn't treat the world as mission. He play role of people who offered him missions.

There are extremist retard Muslims who take seriously about religion on fictional fantasy novels. Chinese authors always made villain ,and then label to Buddhism as hypocrite shameless bald monks, Christian as pope who brainwash to their followers in the name of God, Paganism (Hinduism, Western mythology gods and Shintoism) as Cthulhu or evil gods. If there were no racism and nationalism, everyone enjoyed those novels (even religions portray as villain organization).

Mc should have mastered hacking skill that will be useful in many urban worlds.

Average good novel but the bad thing is harem. Harem always ruined good novel. MC almost collect heroines from every world he traveled. There is no lack of beautiful girls in the cultivation world. Why mc choose heroines only. He is friends with protagonists from other worlds, except for soul land. Those protagonists consider him as brother and best friend, but he puts those protagonists' future wives(heroines) in his harem. What kind of mentality does that guy have?

Good novel. Interesting plot.
