Heine stepped up, followed closely by the skeleton, and together they were transported to the platform atop the giant tree.
There lay a massive black box made of rocky tree bark.
Inside was the "super huge Shadow Essence" that Wei Dianyuan had extracted and solidified using the Banishment Technique, and Lourdon had added another layer of protection around it.
But next to this box was another jar.
This jar was almost the same size as the sugar jars Heine had seen in his childhood, with at least a 2L capacity, and appeared to be made of glass, filled with squirming grey, turbid mist.
"What's this?" he asked.
"This is Milton's Soul Niche," Lourdon answered. "His Soul Niche has always been in my possession for safekeeping."
Heine understood immediately.
This was the most important thing for a lich. As long as the Soul Niche was intact, no matter how many times the body was destroyed, resurrection was possible.
