Jacob remained baffled for a little while when he thought about what had just happened. Not only he wasn't able to get the Earth Fruit of Vitality, but he wasn't even allowed to touch it before he went to the next level.
For some reason, this left a sore taste in his mouth and made him somewhat resentful. After all, he expects to get that fruit as a reward for his labor and all those atomic bombs he had used.
If anything, he hoped to get at least a seed of Earth Tree of Vitality so he could nurture his own, yet the tower didn't allow it.
Jacob knew that fruit was extraordinary. Not only did it have a huge amount of vitality, but he felt pure soul force in it when it was fully ripped. He knew that if he could eat it, his soul force might quantitatively increase or undergo some changes.
