Although he passed the examination, Peter Brown knew in his heart that the suspicions about him had not been completely removed; his cultivation was still a point of doubt. If he could quickly advance to the Immortal Realm, then those suspicions might truly be lifted.
Confined to this room day after day, not even Benjamin Woods and Huxley Brown were allowed to enter. Given several bottles of elixirs, Peter didn't need to think too hard to understand that they were waiting for him to recover his cultivation.
After all, Leo White had been at the Immortal Realm rank before his fall. It should be relatively easy for someone to recover their former strength in such a scenario, provided they had enough elixirs. Now, they had handed him a few bottles of elixirs, clearly to see how long it would take for him to recover.
