Sam and the Saint both started taking a break.
They are waiting for their third target.
While waiting, Sam tried to concentrate on recovering his spiritual energy as much as possible. By now everyone must have noticed his cultivation level. Even if they didn't they will be having doubts.
So, he has to make sure that their doubts remain doubts. If a real Peak stage transcendence cultivator of the Astral plane did the same healing as he did, there is no way they would be able to recover as fast as Saint.
But Sam can at least show off that he did since his normal energy level is already way higher than a normal cultivator of the same level.
He needs to keep his identity and strength as mysterious as possible so these people will stay away from him. At least before they could confirm anything.
