Finally, 11 hours later, Sam can extract every little bit of dark spiritual energy from the world tree.
It almost took him 2 days to do that, but finally, he succeeded. Sam was completely exhausted after finishing all of these.
Continuously he was using spirit potions. But even with that, he is unable to recover most of his mental energy, which makes him that much exhausted.
But he cannot stop the process. Immediately he begins to bring out all the moonflowers and then begins to see the magical thing.
The world tree begins to absorb those moonflowers one by one. It was like a hungry person who finally got the chance to eat something.
Previously, Sam thought he needed to interfere with this and needed to channel the essence of those moon flowers inside the world tree.
But it looks like he did not have to worry about that. During this time Sam gets the chance to focus on his recovery.
