After the new black hole returned inside Noah's chest, Snore's structure changed. The new dark matter was so dense that it appeared to be liquid, and the Blood Companion obtained those properties.
The new dark matter replaced the old one and improved Snore's body. The Blood Companion also inherited the instabilities of the black hole. Still, Noah would fix that temporary flaw once he regained access to his cultivation technique.
Noah returned to the surface as those changes happened. He felt tired due to the lack of darkness in his dantian, but his excitement knew no limits now that he could leave the world whenever he wanted.
The fissure leading to the Immortal Lands slowly closed as Noah waited for his condition to stabilize. He couldn't do much without darkness, but his Demonic Sword improved quickly now that his entire being had reached the divine realms.
