How does the ghost demon village reach the trial four?

The first stage is 1000 with 1000

After durable to zero, it will advance to the second stage

After using it again, enter the third phase of durability

Then use the durability to enter the four stages again!(What is it

Then I got an ordinary 7500 durable ghost demon village that was durable.

If you use the stars of the lower boundary in the third stage of the trial, you will get it

If you are forging with Yanzang
