Why can't I draw a sign when I see you sailing against the current?

1. Sailing against the current is a game set in ancient rivers and lakes. Yu Jian in the game is a mysterious figure, and the game settings cannot be drawn.

2. The plot development in the game needs some suspense and drama. Yu Jian draws lots for players at any time, which will weaken the tension and attraction of the plot.

3. Drawing lots is a random way, which will have a certain impact on the balance of the game.
