Isn't Shen Yanxiao worried tht someone else with a Mythological Beast will come and detect the high-rank demons?

Anything can pop out of thin air Thete bo lacky

Mythological beasts were at least rank 12, so even though they said rank 10 or higher nuclei, I doubt that there's rank 12 onesin that staff.

Well many of the nucleu should be old things left by they ancestors thinl during war with demons many mytologic beast die and they only make one each 100 years 10 nucleu last to 1000 years

It's rare but it's not lacking

There may beany mythological beasts hiding in their own nests

Be many*
