Before entering the mountains, each person gets a piece of jade token. If you are in danger, simply crush the token. It will automatically be considered a failure, but if you crush it, it will not be a failure. The jade token is rudimentary, and after crushing it there will be a gap of time between the actual time of the teleportation and your death. An hour later, he says, he only has one piece of advice: "come back alive". This time, instead of entering through the jade token, he will enter through the random array. This way, he has less chance of meeting with people he knows. The son of the Emperor is offering a prize of 10,000 silver coins for each man killed. If he has the most blood crystals after five days, he gets a bonus.
