Im looking for a novel where the prologue goes like, "The MC(soul) wake up in heaven where he will be reincarnated to his Next Life. There are many other souls there and one of them holding like a pouch, which gonna give you a benefit in your Next Life. The MC then steal that pouch and run away with the pouch. Opening the pouch, he got like a tablet/slate which shows his status and can temper his status with it". Iirc, he got assassin job after reincarnating(not sure). Idk whether it was a novel or a manga, so hope anyone can help with this. Thanks.
