Riding the Clouds and Riding the Wind

Ten thousand years after the six realms of immortals, humans, demons, Buddhas, ghosts, and monsters merged into one, Jiang Chuan transmigrates through time after being struck by lightning and killed. Here, the Demon Realm and Ghost Realm are preparing to join forces and carve up the human race, while the Monster Realm remains ambiguous, and monsters are appearing more and more often in forbidden zones. In this brutal world, he starts pulling all kinds of crazy stunts: tricking divine heirs, kidnapping saintly heirs, auctioning off saintesses... He keeps his head down and grows stronger, choosing to lie low whenever possible and never fight fair if he can gang up on someone instead! If he doesn't like the situation, he calls in backup! And if all else fails, "Honey, get in there and smash him!"

A schemer + shameless + underhanded + great at calling for backup + no System + smart protagonist
