Chương 237: SS-Grade Super Brain

Yang Xi saw that there were still more than 20,000 units of dark energy cubes left. He thought about upgrading another SS-level ability.

"After all, the enemies we have to face in the future will definitely become stronger and stronger. If we continue to use S-class abilities for the zodiac position, it will be a little embarrassing.”

Among the remaining accounts, Yang Xi decided to prioritize upgrading Youji. After all, this was his first account and also the beginning of Judgement.

"Then the next decision is to upgrade my metal control or my mental ability first.”

The Youji was one of the more powerful ones among the many zodiac characters.

Because of the vague boundary between mental powers, as long as it was a mental power, Yang Xi would not break his character if he used this avatar.

In theory, the Youji avatar could use more abilities than the Chenlong avatar.
