Tina used her Mental Power to slowly probe the stone door, hoping to see what lay behind it. If there were any Monsters, they could at least be prepared.
But she found only darkness behind the door, nothing else. The entire door was made of stone over half a meter thick and was extremely heavy.
As a result, probing through it with her Mental Power was very difficult. She could only detect a space a few meters beyond the door.
Yet even at that distance, she had not detected the passage entrance. The stone door had been carved directly into the rock, surrounded entirely by stone. The rock was over ten meters thick, so even after opening the door, they would still have to pass through a nearly ten-meter-long corridor before reaching the actual space beyond.
The entire structure was like a stone door carved into a Rock Wall, followed by a corridor more than ten meters long. The door itself was around seventy to eighty centimeters thick.
That thickness consumed too much of Tina's Mental Power, making it impossible for her to probe farther behind the door. It was clear from this alone that Tina's Spiritual Sea was worlds apart from Chen Mo's.
