One breath, two breaths, three breaths... Bang!
At last, the Beast Heart Body was blasted to pieces by the ninth-grade Yin Spirit Evil Qi.
Sikong Jing's true body within the passage spat out another mouthful of blood.
Yet when he raised his head, a sharp gleam flashed in his eyes as he rasped, "My Mad Beast Sword Dao is now enough to confront eighth-grade Yin Spirits head-on, while ninth-grade Yin Spirits have given me even more inspiration for the Burial Emperor Sword."
Drawing ninth-grade Yin Spirits into the Beast Heart Body allowed him to truly experience ninth-grade Yin Spirits...
Do not forget that the Sword Extinction Emperor's method of cultivating the sword was to use Yin Spirit Evil Qi as a means of enlightenment.
Just as Sikong Jing's true body sat cross-legged, preparing to contemplate it...
Awooo!
Suddenly, a strange beastly cry crashed into Sikong Jing's ears, as though it had come from the depths of the Burial Emperor Battlefield.
Sikong Jing froze and instinctively looked deeper into the passage...
"What was that sound?"
"It didn't sound like it came from the depths of the passage. It sounded more like it emerged from one of the ruptures—almost like some kind of mournful cry?"
"Or perhaps... a call?"
He muttered his guesses, unable to make sense of it. There was nothing within the Burial Emperor Battlefield; aside from battlefield Yin Spirits, there could be no living creatures. Even if there were, they could only exist at the battlefield's edge.
Like Bian Guo!
Unless it had come from the other direction of the passage—but that did not seem likely...
"There is another possibility: new Origin Universe invaders have entered the passage and are heading toward the Vast Universe."
"And some living being may have fallen into a rupture and died."
