Why can't peaceful elites eat watermelons to increase their health value?

Because according to single-player matching or multi-player matching, when the loss of health is "0", it will enter the state of elimination or falling to the ground. The elimination of the former means that in the case of single competition, there will be no teammates and the game will be ended directly on the spot. The latter state of falling to the ground can be helped by teammates. After being released, the health value will return to the position of one tenth of the health value, and the remaining health value needs to be restored by drugs.
