Kill the big boss of Ice Valley, then bring a centering symbol, you can enter the reincarnation from the door it guards, and then go directly to see a teleport, from which you can see the crying ghost on 18 floor;

Generally, it is more than 3 to hit 18, and there is no hero on 18 floor who can resist crying ghosts. Even if you can kill the industry, you have to drag it slowly with your skills, otherwise you will have to die several times to drain the blood of BOSS.
