"[The weak Wandering Soul awakes in a shabby hut in the wilderness...]"
Lin Xun expends 1 point of Soul Strength to reconstruct the Yellow Bishop.
After possession, he summons three lions and returns to the lip of the tomb's pit.
"[The pit ahead is over two meters wide, the bright moonlight in the dead of night only illuminates the earth walls above the pit.]"
"[As you lean over and look, the depths of the pit appear as an endless darkness.]"
"[Do you wish to jump into the pit on a lion?]"
Due to limited Soul Strength, after reconstructing the Yellow Bishop, Lin Xun cannot reconstruct a warhorse and can only use the three lions as a cushion.
Furthermore, to ensure both the Dancer's Shell and Engineer's Shell remain intact after jumping into the tomb, he could only spend Soul Strength to reconstruct a disposable shell.
It wouldn't be right to say it's a death sacrifice, more of a disability sacrifice.
