Lind became deeply interested in the tower amidst the Abyss.
The thing was big enough and seemed very sturdy; if used to crush someone, the force would definitely be extraordinary. The only problem was that it wasn't convenient to take away.
It had taken root in the underground world, merging with the earth itself.
The interest Lind showed toward the Rock King here was immense. It wasn't a time for the Abyss to invade the surface world but for the surface's Expedition Army to take an interest in the tender lambs of the Great Rift, with the Abyssal Great Rift symbolizing materials, resources, and all sorts of valuable things.
To be cautious, it might be better to wait a bit longer. Lind's resources had piled up to a terrifying level, even to him. If he couldn't digest them quickly, it was highly likely that the warehouse storing the Heart of Calamity would transform into a super-large Calamity Shadow region, spawning countless calamities.
