That was right. Chi Xue and the others had previously reasoned that they should kill all the Heavenly Slaves while Ling Tian was breaking through to the seventh stage of the Quasi-Saint realm. So they had always had an opportunity, since Ling Tian and the others wouldn't pose much of a threat to them before reaching the seventh stage. Even if Ling Tian and the others managed to break through after Chi Xue and his companions had killed all the Heavenly Slaves, it wouldn't matter much. Chi Xue and the others would still have plenty of advantages, such as their greater number of super experts and their higher cultivation realms. Chi Xue and Po Tian had already broken through to the seventh stage of the Quasi-Saint realm, and their team even had experts at the eighth stage and the peak of the eighth stage.
At that, everyone stopped worrying. Besides, they realized that by then the Outer Realm Demon Race would pose an increasingly serious threat to Ling Tian and the others, so they were the ones who ought to be worried. They put those concerns aside and continued dealing with the Heavenly Slaves, hoping to kill as many of them as possible before Ling Tian and the others arrived. After all, they wouldn't get another opportunity like this.
With no Outer Realm Demon Race cultivators harassing them, and Dragon One and Dragon Two flying at top speed, Ling Tian and the others reached Chi Xue's group before long. Then they once again joined forces against the Heavenly Slaves. Ling Tian and the others had grown much stronger overall, so under the pressure of their formidable strength, Chi Xue's group posed an even smaller threat to the Heavenly Slaves. It often took them a long time to kill even one.
