"Communication"

Lumian wasn't surprised when his wrist was grabbed by the wet hand.

He even chuckled. "Not bad. You only stained my wrist, not corrupt my entire arm."

As he spoke, he pulled back with all his might, feeling the abnormally heavy force opposing him.

Lumian's muscles swelled, and his body appeared to grow slightly larger.

At last, he saw the bloody figure in the jacket being dragged out of the empty mirror.

A bluish-black mist materialized, permeating the faux goatskin containing the ominous contract.

The contract burst into flames on its own, morphing into silver-black symbols and words. They linked together from end to end, creating an intricate and illusory pattern that abruptly passed through his clothes and settled between Lumian's chest and abdomen.

Having pulled Bloody Jack out of the mirror, Lumian had fulfilled the other party's request, and the contract was automatically fulfilled!
