Po Tian killed the Heavenly Slave, and no second one had appeared yet. This left Po Di and the others greatly encouraged. They were even more convinced that Chi Xue and the others' earlier guess had been correct, and they were eager to see what came next. If Po Tian used his true strength again later without drawing another Heavenly Slave, their guess would be confirmed beyond doubt. Then he could unleash his full strength without restraint, and capturing powerful Ancient Divine Beasts would become much easier.
Most importantly, once Po Tian could use his true strength, the overall power of their alliance would increase considerably. They would have a much stronger ability to protect themselves, whether against Ling Tian and his people or the Beast Taming Cultivators.
To confirm Chi Xue and the others' guess beyond doubt, Po Tian would have to display his true strength once more. But they needed to wait a while. Killing the Heavenly Slave had taken a great deal out of him, and if they were wrong and another Heavenly Slave attacked, Po Tian might not be able to handle it. Besides, he had only just revealed his true strength and killed the Heavenly Slave. If he did so again so soon, there was a good chance he would draw another one.
Po Tian began cultivating to recover, naturally doing so at their sect's stronghold. That way, even if a Heavenly Slave came after him right away, they could stand against it with the help of the sect's stronghold and might even kill it. At the very least, they could escape using the large Teleportation Formation. In short, they would be safe.
Many powerful experts in the God Realm sensed that Po Tian had killed a Heavenly Slave, and the news caused an uproar.
