As a seasoned sovereign, King Qingyang had a rich foundation.
After an exchange, Su Heng gained Enlightenment Tea and a large supply of Potential Secret Medicine that could enhance spiritual power from King Qingyang, while King Qingyang obtained an amount equivalent to one-tenth of the remaining True Dragon Remains from Su Heng.
Both were very satisfied with the outcome.
While Su Heng's physical strength had already reached its limit, his spiritual power had somewhat fallen behind.
As for King Qingyang, his physical body was far inferior to Su Heng's. Even with just that bit of dragon remains, he would be able to fully recover from his injuries and even make some progress in strength.
Over these days of exchange and discussion, both had validated their past cultivation experiences against each other's.
They both felt they had profited tremendously.
King Qingyang began to seclude himself, refining the dragon remains to heal his injuries.
