Gongsun Haoyue and Han Yi had already moved far away from the Source of the Netherworld when they sensed something during Heaven's Dao's first attack on it.
The Sea Turtle, which had been flying, suddenly dropped from midair.
Moreover, as a Saint Realm cultivator of the second rank, Han Yi could clearly sense that the enormous face overhead was attacking the Source of the Netherworld.
The moment that enormous face appeared, Han Yi had already felt an immense spiritual pressure—even though Heaven's Dao had not targeted her.
Faced with Heaven's Dao's powerful pressure, Han Yi did not even need to urge it on. The Sea Turtle immediately dove into the seabed and sped away.
At that moment, the Sea Turtle could no longer care that Dark Primal Qi remained on the seafloor.
Only after leaving the waters around the Source of the Netherworld did the Sea Turtle slow down and rise back to the surface.
"Elder Sister Gongsun, was that thing that appeared just now Heaven's Dao?"
Although Han Yi had experienced Heaven's Dao's immense spiritual pressure, she had never faced it directly and had not known that its strength could be so terrifying.
Gongsun Haoyue nodded. "Mm! It was the one that ambushed me before."
"Then is Heaven's Dao attacking the Source of the Netherworld?" Han Yi asked doubtfully.
"Judging by the force it unleashed, it should be." Gongsun Haoyue nodded.
Gongsun Haoyue had heard Jiang Liu mention before that, according to his deduction, Heaven's Dao's duty—and its desire to advance and break through—required it to control the Darkness Substance and prevent it from entering this world.
Otherwise, the entire continent would have been conquered by the Nether Race long ago.
Upon hearing this, Han Yi could not help worrying about the Frost Race members in Abyssal Hell.
