Using the Heavenly Oath was the perfect solution for keeping it secret. "So what do we have to do in the mine?"
Mo Yan looked at him with an amused expression. "What else? Mine of course. We need to store a lot of spirit stones in case the situation turns bad, although something like that happening is almost impossible. Being prepared is always better.
Not to mention we need spirit stones to set up strong killing arrays as traps in various locations on the border area, where we can lure the enemies."
It would be a tremendous task, as even the border area was massive. But since they would only be using particular areas to lure the enemies, it would be fine. Not to mention in the Northern Region there were other sects under the Frozen Heart Sect that would help.
"So we will be defending?" Since they were planning to create killing arrays inside their own territory, it was obvious.
