The moment he slew the Yama King, Han Yi had already activated the Wan Ming Tome.
Behind him, as the shattered Yama King dispersed, a godly fluctuation was extracted and was about to merge into Han Yi's body.
In Han Yi's eyes, there was no ripple of surprise, but his heart had already slightly tensed.
His cultivation of the Wan Ming Tome had been stuck at the Nether Slave Demigod Volume at 90/100 for far too long, nearly a thousand years by now.
His gaze landed on the panel.
Upon absorbing the fluctuation from the Yama King, a line of information on the panel began to change.
[Wan Ming Tome (Nether Slave·Semi-Immortal Chapter 91/100)].
Then, this progress rapidly climbed upwards, reaching 100/100, paused for a moment, and turned to a new page.
[Wan Ming Tome (Netherworld Soldier·True Immortal Chapter 0/100)].
After ascending from a Nether Slave to a Netherworld Soldier, the progress did not stop there but climbed further to 19/100 before coming to a complete halt.
