(One Piece, slice of life, summoning, no harem) Tian Cheng, a freeloader who lived off his parents and worked at an electronics factory, transmigrated into the world of One Piece and became bound to a cross-dimensional Summoning System.
He woke up in Water 7 and was kicked unconscious after trying to hit on Kalifa. For the next six months, he survived by relying on Lazy Goat to steal food.
Repeatedly humiliated when he had no strength, he learned that the weak weren't even qualified to go on adventures.
Then he unexpectedly gained the ability to summon people from across the multiverse to join his crew.
His first summons: Lazy Goat steals cake, Tom repairs ships, A-Jie protects the ship, Big Big Wolf builds mechs, and Kanna destroys the world in a fit of rage.

It's just that love doesn't have the nature of a lazy sheep at all.
