How did you get the beast essence of the demon domain? Can you detonate it?

Can't explode, can't buy, can't do the task. Go to Shuxin City to receive the task. There must be two BB's with 15 stars, one mage and one warrior to attack and defend. The philosopher's stone didn't explode. You can exchange gold coins, you can exchange with players, you can shout in the world, and you can also shout in the warehouse. There are 654.38 billion gold coins in the new area, about 750 sorcerer's stones, and 500 sorcerer's stones in the old area.
