Chapter 687: Get Your Revenge on the Spot!

The immediate priority was not to complete the trial tasks set by the system.

It was to boost his strength!

The strength training too was a task, and the rewards were decent.

Jiang Xiaobai had already upgraded the Kunpeng Swallowing Sky Skill to a higher tier, which was suitable for the time being.

"First, I'll elevate my strength to the peak of the Tribulation Crossing stage, or maybe I should aim for Great Completion?"

With this thought in his mind, Jiang Xiaobai started his training straight away.

Retrieving the record of Earth Veins, he began absorbing the celestial stones.

Time flew swiftly.

In one night, Jiang Xiaobai absorbed nearly seventy million superior celestial stones.

At last, he upgraded his strength and reached the Great Completion of Tribulation Crossing stage.

The remaining two hundred million or so superior celestial stones.

They should be able to lift him to the state of Great Achievement, right?

"Damn it, this isn't enough!"
