Zero soul strength meant the death of the apostle's physical shell.
He wondered how Amos had obtained such a bookmark made purely for killing.

[You enter the castle hall, where a silver-haired old man has been waiting for a long time.]
[Wearing a top hat, a black tailcoat, and holding a silver cane.]
[The 'Castle Butler' steps forward to ask if you want an exclusive brand imprinted on your shell?]
This is an NPC within the castle and has some special functions, one of which is to imprint the New World's exclusive brand.
Lin Xun thought for a moment, he couldn't reveal his engineer's shell explicitly, so he had to use another one to imprint the brand, and at the moment, he was possessing the shell of the Earth Giant.
He wasn't sure if Amos was still watching in secret, and changing his shell instantly might cause unnecessary trouble.
