The Heavenly Purple Pearl was indeed a Supreme Treasure, said to be a condensed form of the Open Heaven Purple Light.
Heavenly Slaughter had obtained this treasure; no wonder he was so confident, aspiring to become the Master of Domain.
Normally, with Heavenly Slaughter's means and the Heavenly Purple Pearl, his chances of seizing the Domain Authority and ascending as the Master of Domain were very high.
Even if he couldn't fully control the Domain, he could at least obtain more than seventy percent of the Domain Authority, making him the strongest in the Taicang Domain.
Unfortunately, Heavenly Slaughter ultimately had a limited understanding of the Taicang Domain.
The Taicang Domain was different from the other Six Great Domains, not only because Taicang had made some arrangements, but more importantly because of Tian Zi's presence.
