One Piece - I Am A Different Luffy! - Chapter 2 - 1 - Start.

An Individual from Earth finds themselves in the Shinobi World, equipped with a Scientific System. From that moment, he delved into scientific research far ahead of its time.

Shen Dongqing is a powerful, thousand-year-old ghost. He had just possessed a body and hadn’t even relaxed for two days yet when he was pulled into a white, parallel world.

On the first day of the Infinite Nightmare Game:
Other players tremble, crying and wailing wanting to go home.
Shen Dongqing eats, sleeps, and plays ‘Fight the Landlord’ (card game).

The second day:
Other players are chased endlessly by ghosts, crying loudly ‘Save me!’
Shen Dongqing eats, sleeps, and plays ‘Fight the Landlord’.

The third day.
Shen Dongqing……
The ghosts finally set their sights on this lazy player. The other players watch on in glee. As a result, who knew that this slim and pale youth would stand up and easily dispatched the ghosts with his bare hands.

Other ghosts: Can’t afford to disrupt this elder. Let’s go, let’s go.
