The biggest worry for a guardian is a master coming to cause trouble.
And in this Demon Suppressing Tower, the only master left unseen by Basil Jaak is the Immortal White Wind.
The passage of time in the Demon Suppressing Tower is unclear, and Basil doesn't know how long he's been inside this tower, as the environment here is always dark, indistinguishable between day and night.
So, Basil also doesn't know how long the Immortal White Wind has been gone to play chess with his old friend and if he's ready to return.
If he comes back at this time... Damn, Ina is guarding, Bertha and Arm are outside dealing with the Netherworld Ghosts, and when it comes to confronting the Immortal White Wind, it'll just be me again!
Basil recalled the scene when he fought against the Black Wind Immortal Lord, damn, he reckons that if he were to fight the Immortal White Wind, he'd get absolutely crushed again?
