Now, as Chen Nianzhi's cultivation continued to break through, the Guixu Universe became ever more vast and majestic. In the blink of an eye, it surpassed four hundred million light-years, only gradually stopping when it neared four hundred and fifty million light-years.
"It is said that a universe belonging to an eighth-level Heavenly Immortal has a diameter of roughly two hundred million light-years."
"Even a Heavenly Immortal at Great Perfection possesses a universe only three to five hundred million light-years across."
"My Guixu Heaven is already four hundred and fifty million light-years in diameter. It is larger than the universes of many Heavenly Immortals at Great Perfection."
Chen Nianzhi murmured inwardly. He roughly assessed his current combat strength and found that, while he did not dare claim he could contend with a ninth-level Heavenly Immortal, he should rank among the absolute strongest at the eighth level.
Even if three or four ordinary eighth-level Heavenly Immortals joined forces, Chen Nianzhi estimated that he would not fear them in the slightest.
At this thought, blazing light bloomed in Chen Nianzhi's eyes. At last, he looked toward Guixu Heaven, drew a slow breath, and said,
"The universe cannot advance further in the short term, but I can still use this breakthrough as an opportunity to open several more heavens and earths."
With that thought in mind, Chen Nianzhi mobilized boundless mana and poured it into his five natal immortal treasures.
In an instant, an ancient bell boomed, a precious mirror soared into the air, and an immortal sword stirred the six directions. One world after another was carved open within the chaos.
No one knew how long passed. When all finally settled, Chen Nianzhi found that four more heavenly domains had been opened within Guixu Heaven.
"Twenty-eight heavens."
Chen Nianzhi murmured to himself.
