Chapter 372: Three Thousand Years Have Passed

The moment this exaggerated number appeared.

An Kai was stunned.

The lowest was 100,000, and the highest was 1 million.

He did not know if the other living beings in the Abyss who practised the Abyss Bodybuilding Technique would also need such an exaggerated amount of resources.

However, according to the resources An Kai needed to practice spells compared to others, he estimated that he was probably the only one who needed them.

The system had already given an explanation.

The amount of resources needed was based on An Kai's physical fitness.

Thinking of this, An Kai didn't know whether to cry or laugh.

The two upgrades required a total of 2 million Goblin Cores.

As for what the [Abyssal Aura Materialization Core] was, An Kai did not know.

Therefore, his target was only the Goblins.

There were definitely more than two million Goblins in Wealth Abyss.
