The Giant Turtle Rock Platform slowed down and gradually approached the shattered region deep beneath the ground, while the three drones detached from the formation first and began a comprehensive, detailed scan of the area.
This hollow was already at the deepest part of the mantle, right beside the molten core. The extreme temperatures made it resemble an inferno. Inside a normal planet, no stable hollow could possibly exist in such a place of high temperature and pressure. Everything here would be devoured by magma, and any hollow or fault would collapse—but the Firstborn's existence had made this celestial structure, which violated the laws of nature, a reality.
All around the core were hollow regions like the one Hao Ren had seen. The Firstborn's tentacles had hollowed out and reinforced these places to accommodate its enormous organs or serve other purposes. The scenery in these hollows was both spectacular and horrifying: above was a scorching, solid dome thousands of kilometers thick, while below churned magma and extremely rare floating islands solidified by the Firstborn tentacles. Connecting the two were thick tentacles and crimson deep quartz pillars. Because gravity was weak, the droplets produced when the churning magma struck those tentacles and quartz pillars drifted slowly downward like they were moving in slow motion—beautiful and deadly.
Beneath the magma was the molten core, but the Firstborn normally did not soak directly in it. Instead, it grew around the core and buried its brain core in a cavern deep within the mantle. Hao Ren believed that the rock walls covered in countless main tentacles concealed such caverns behind them.
"Based on the shape and orientation of the Great Rift we passed through, this should be the 'deep structure' exposed when the Firstborn opened up the crust back then. See those shattered tentacle
