The two small black iron balls flashed past like meteors chasing the moon, and Tang San's purplish-red eyes met Shi Nian's at that very moment.
Tang San's eyes were filled with indifference, but inwardly, he found it regrettable. What he had used was only the Mother-Child Soul-Chasing Life-Taking Gall, not Yama's Invitation.
Though both possessed the effect of chasing souls and claiming lives, the power of the Mother-Child Soul-Chasing Life-Taking Gall could not be mentioned in the same breath as Yama's Invitation.
As the saying went, when the King of Hell called for you to die at the third watch, who dared keep you alive until the fifth? Yama's Invitation was precisely such a terrifying super Hidden Weapon.
As the third-ranked super Hidden Weapon in the Hundred Variations of Hidden Weapons within the Mysterious Heaven Treasure Record, the terror of Yama's Invitation was easy to imagine.
Yama's Invitation had two effects, also known as one post, double kill. It required at least dozens of deadly poisons to refine and was nearly impossible to cure. The slightest touch meant death.
Even if one severed the limb the instant the poison needle entered the body, it would still be impossible to stop the poison from spreading instantly.
Beyond its poison, the most terrifying aspect of Yama's Invitation was its structure. It was not metal at all, but entirely condensed from poisonous substances. Once it entered the human body, it immediately transformed into lethal poison and took effect in an instant.
