Just think about it, it's impossible. How big is the karma of the Fire Cloud Cave? You should know, Fire Cloud Cave was given to the Human Race by the Heavenly Dao, not something the Human Race seized.
In reality, the Human Race doesn't owe Ancestor Red Cloud anything; if anyone owes him, it's the Heavenly Dao. The Human Race just took the blame on their behalf.
Under such circumstances, the so-called karma of the Fire Cloud Cave is actually not that great. A high-grade Innate Spiritual Treasure or a top-notch Cave Heaven would suffice, there's no need to involve the Buddha Realm.
Even if merely making Ancestor Red Cloud the master of the Buddha Realm for a time, Jiang Chen would surely suffer losses.
That's why he said it was for the sake of the two Western Saints, not only to resolve the karma with Red Cloud but also to take the opportunity to make each of the two Saints owe him a favor.
Calculating like this, Jiang Chen wasn't actually losing out, but instead gaining.
