When the three True Lord Ranks were in a dangerous situation, Zhao Feng had reached the peak True Mystic Rank with the help of the Tree Yao Essence Fruit.
Because he had eaten the Tree Yao Essence Fruit in a rush, Zhao Feng wasn’t able to fully absorb the energy.
His Source of True Spirit couldn’t expand anymore as it had reached its limit.
To not waste anything, Zhao Feng sealed part of the Tree Yao Essence Fruit in the Water Moon Pirate’s Source of True Spirit.
At the peak of the Water Moon Pirate’s Source of True Spirit, it was larger and pure than Zhao Feng’s. However, this Source of True Spirit was on the verge of being used up. But after the life force of the Tree Yao Essence Fruit went into it, it started to recover.
“The Water Moon Pirate’s Source of True Spirit is not only a second storage. It can also be burnt at critical moments.”
Zhao Feng also knew this was one of his cards, but there was no situation that needed Zhao Feng to burn it yet.
