I! Lie Down as a Ghost, Reborn as a School Beauty and Beg Me for a Contract

My name is Su Chen. I traveled to a world where terror resurrected, and became a ghost waiting for a contract! Fortunately, I have awakened the lying system, so I can sleep in every day and complete daily tasks to level up! One day, a girl who looked pretty good actually asked me to make a ghost contract? ........... My name is Natsume. After the destruction of my hometown, I was reborn back to the time period of the contracted ghost. I originally thought I had contracted a ghost with super abilities, unlimited potential, and a bit of handsomeness. Turns out this guy wasn't interested in upgrading at all! He had no energy all day long and seemed to be lying flat on his back. He even slept on my lap! But even so, he seems to be getting stronger at the speed of light! Unknowingly, he became the strongest ghost in the world! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
