It was the shortest time that Fang Jinyu had been in the dream.
However, the "shortest time" was only temporary.
It was because the chessboard wasn't ordinary. Every piece placed on it was equivalent to a year's lifespan.
Fang Jinyu's 100-year lifespan was only enough for him to place 100 pieces. Even if he didn't lose in the end, he wouldn't be able to hold on for long. Moreover, if he hadn't been bluffing the entire way and intimidating the other party, the game would have ended very quickly. He wouldn't even have the chance to place 20 or 30 pieces!
After Fang Jinyu returned from the dream, he fell into a miraculous state.
It was because Fang Jinyu had won a hundred chess pieces and awakened the cultivation ability of the body in his dreams! Even though he had left the dream, part of that cultivation ability followed closely behind him and came to reality from the dream.
