Of course, this is not without cost. In exchange, these immortals guarding the national fortune can transfer the cause and effect upon themselves without damaging the fortune.
This is an excellent opportunity for immortals, so most of them were sent to guard the nine tails that happen to disperse, while the remaining immortals were sent to investigate the cause of this phenomenon.
After all, for immortals, cause and effect are a very troublesome thing, and if borne by national fortune, to be honest, it's transferred to the people, which in a way is a different kind of return, with very obvious benefits for the immortals.
Reasonably speaking, the ability of national fortune to bear cause and effect is actually very strong. For most immortals, stealing national fortune and transferring cause and effect to others is a very good method. Of course, the prerequisite is that you must be prepared for protection.
