The reason is simple: the higher the player level, the better these level +1 rewards are, obviously.
The higher the level, the more experience points it takes to level up, so a level +1 means more experience can be added. Going from level 15 to 16 didn't take much experience; the effect of the level +1 was completely wasted.
Unfortunately, the effect of level +1 can't be saved for later use. Otherwise, he really wanted to keep it until he reached level 50 or 60.
"Tsk."
Chen Miao shook his head with a hint of regret but quickly came to terms with it. It wasn't too bad, after all; he was now at level 16, not too far from his goal of level 20. At level 20, he would be able to see what that S-grade Taboo Item Lord Miao had left for him was all about.
He didn't know if Lord Miao had really died.
Or if he had reincarnated.
While he was lost in thought, Hungry Monkey and the others had noticed that Miao had returned and swarmed over to him.
...
"Miao!"
