Although they suspected the Lord of the Universe might be exhausting the Creation Divine Tree, the World-Ending Thunder Dragon, and his own Origin Power to prepare for the final battle, Po Qiong and the others weren't worried. After all, whether the Lord of the Universe was doing this to target Chi Xue and the others or Ling Tian's true self, it benefited them. In particular, the fact that the Lord of the Universe's strength was affected by exhausting these sources of power was beyond dispute.
Most importantly, it was now clear that the Lord of the Universe was stalling for time. For Ling Tian, Chi Xue, and the others, that was the best possible outcome, since it would give Ling Tian's true self, Hua Min'er, and the others a significant chance to improve their strength. The stronger they became, the better their chances of holding off the Lord of the Universe's attacks, and the more likely they would be to defeat him afterward.
Of course, even though they were sure the Lord of the Universe was stalling once again, Ling Tian and the others still remained vigilant and prepared to fight at any moment. They knew the Lord of the Universe hadn't said how long he intended to delay things this time, so he could strike whenever he wished without breaking his word. Only by being ready to act at any time could they ensure their safety.
Time drifted by. In the blink of an eye, decades and then a century passed, yet the Lord of the Universe still hadn't begun the final battle. Ling Tian's true self was more than happy with that—he even hoped the Lord of the Universe would stall longer. Several tens of thousands of years, or even over a hundred thousand, would be better still.
