บท 126: The Vampire Elder's Inheritance

Rex was instantly attracted by the massive 2-colored door.

Rex secretly hoped for a system mission notification to pop up as he looked at the door but he was disappointed this time, apparently, not every single thing that he did would be turned into a mission by his system.

After removing his mind from the system mission, he finally focused on the door. The left side of the door was green, while the right side was colored red.

Instantly after he looked at the red side, Rex felt his body resonating with it. On the right corner of the red part of the door was a port that could fit in a massive book, as Rex kept on looking at it, his eyes suddenly widened in realization.

Before Princess Elanor could question his actions, Rex accessed his storage ring as his Blood Tome appeared on his hand the next moment.

When he looked at it now, the size was exactly the same. His Blood Tome was actually the secret key to activate the red part of this door.
