A Chain Drains a Man's Blood, and His Lifespan Shrinks Along with It

That lock wasn’t an ordinary gold burial lock. It was a “Life-Sharing Lock,” fastened to eight chains called “Lifespan-Locking Chains.” They were all objects of extreme yin and evil. Thread the eight chains through the hearts of eight people, and after soaking in their heart’s blood, the chains turn red. Then hold the Life-Sharing Lock in your mouth. After one night, you’ll be radiant, even returned to your youth. If a ghost uses it, it can bring the dead back to life and let them possess a corpse.
