The reason for the leak was only to be expected. After all, during the ancient Creation War, although the bridge connecting to the Heavenly Dao space had been destroyed with Multiple Causality, the mutual devouring of Multiple Causality had also consumed part of the boundary wall between the Celestial City Immortal Domain of the Nine Heavens and the outside. That section had been restored through the efforts of Zhao Qian and Han Shanshan! It was easy to imagine how weak it was. Over the years, the rift facing the Heavenly Dao space had never been repaired, nor had it drifted away as we had imagined. It had become a festering worry in everyone's heart.
On top of that, the thermal core of the Heavenly Dao space had continued growing, as though it were accumulating enough power without exploding outright. Thus, as its energy increased, it instead began pouring downward, constantly dissolving the weak outer wall of space. As a result, no one dared live in the former Celestial City Immortal Domain anymore, nor was there anywhere to live. This had indirectly become the reason the new Celestial City area had taken shape like a circular ring.
Over the years, it was not as though we had failed to limit the growth of the Heavenly Dao space's thermal core. We had tried diverting energy into the spatial barrier, repairing the spatial rifts, and even attempting to draw the Heavenly Dao space away. It was just that, from what I heard, there had been many methods but none of them had worked, so the matter had continued to drag on until now.
Of course, the countless measures had not been entirely without effect. According to Han Shanshan's calculations, aside from the occasional solar-flare-like eruption that would break through the boundary wall of
