If the Lord of the Universe still had secret arts capable of threatening Chi Xue and the others, he would have taught them to the Demon Soldiers and Nine Nether Nether Soldiers long ago, rather than making the Demon Soldiers burn their Origin Bloodline Power. After all, once they burned their Origin Bloodline Power, the Demon Soldiers were sure to die. This meant the Lord of the Universe had run out of tricks. He clearly wanted to keep a large number of Demon Soldiers alive to stop Chi Xue and the others from reaching the Demon God Forbidden Ground, so the more survivors, the better. Now he was willing to make them burn their Origin Bloodline Power, which was proof enough that he had no other means to teach them—no means that could then threaten Chi Xue and the others.
Once they were sure of this, Chi Xue and the others were greatly encouraged. At last, they no longer had to worry that the Demon Soldiers might have other secret arts. More importantly, judging by the situation, even with their Origin Bloodline Power burning, the Demon Soldiers could not pose much of a threat. It even looked as though Chi Xue and the others might still have some formations left after dealing with all the Demon Soldiers. Keeping those formations would undoubtedly let them put the Lord of the Universe under even greater pressure, and they might even force him to stall for time once more. All of this worked in their favor.
At that moment, however, Ling Tian's Clone brought up something that worried everyone: the Lord of the Universe had no means left to threaten them, which made it very likely that he was about to launch the final battle.
At that, the smiles froze on everyone's faces.
