The Duke of Thunder used space movement, flickering continuously within the restriction, and quickly returned to the crater.
The crater, having lost the Heavenly Mechanism Treasure, remained in a sealed state.
The Duke of Thunder followed the crater downwards, descending a hundred meters, vaguely seeing the red magma below. Using the glow of the red magma, he could see a transparent section of the volcanic exit passageway.
This transparent section of the volcanic passageway vaguely revealed the underground facilities established around the crater.
The Duke of Thunder arrived in front of the transparent wall, reaching out to touch it, confirming through his perception that it was also constructed through ancient restrictions, capable of blocking the high-temperature seawater from the crater.
The Duke of Thunder's hand was blocked; it seemed this transparent restriction did not allow life to pass through.
