Khan finished absorbing the mana accumulated through the [Blood Vortex] in under a day but didn't immediately depart to face the heaviest echoes in his brain.
That training session could be Khan's doom, but he didn't delay it out of fear. He could still prepare better, and adding another day to his timeline would give Garret a higher chance of dealing with the worst-case scenario.
Sadly, Khan had already dealt with the main preparations. The remaining ones only involved eating again and resting. He didn't need to, but the imminent training session's danger forced him to remove every possible variable.
Khan indulged in another feast before sleeping on the same hall's floor. His rest never lasted too long, so he eventually retreated to his quarters, showered, and changed into something better suited to the impending project.
