A shrill scream pierced the eardrums, and the sword Qi dissipated. A path was cleared for the numerous Devil Bats.
However, there were simply too many of them. Some of them had died, and the rest were quickly replaced by the rest.
The Black Devil Bat's body fell to the ground like dumplings, laying on the ground.
Wisps of thin black demon aura were emitted from the body, as if they were going to merge with the surrounding air.
But at this moment, a suction force suddenly came from the Heaven-Devouring Holy Light Sword. It sucked in the demonic energy, as well as a trace of blood energy and spirit.
Lingyun was still at the Great Circle of the Warrior, and had not even started to clear out the first gist. He could not release spiritual energy from his body, but the Heaven Swallowing Saint Light Sword could.
Although it had suffered serious injuries and its level had dropped, it had a Sword Spirit that could emit Sword Qi.
As for the demonic energy that could corrode a martial artist's spirit energy, the Heaven-Devouring Saint Light Sword was not afraid at all. It would swallow it up just like that and use it as nourishment for its recovery.
Ling Yun was not worried that the Heaven Swallowing Holy Light Sword would transform into a devil soldier after absorbing the demonic energy, because the Heaven Swallowing Holy Light Sword had the ability to restrain both the flame of the Holy Light and the destructive thunder energy.
Seeing that the Devil Bats were unable to resist the Heaven Swallowing Holy Light Sword's sword qi, Lingyun's eyes flashed with a hint of joy. He no longer hesitated as he slashed at the flock of Devil Bats again and again.
One after another, green lotuses with the sacred flames and destructive thunderbolts appeared out of nowhere, shooting out sword energies in all directions.
He was not worried that his attacks would miss as there were so many of them.
Each sword aura took more than thirty to forty magic bats' lives. The magic bats' corpses rained down, but it did not have much of an impact on the large group of magic bats.
The death of their companions did not scare away the magic bats. Instead, it aroused the desire to kill in their hearts and made them attack even more crazily.
The thick black vines did not let go of this opportunity. They blended into the horde of magic bats and attacked the invisible light screen.
With every swing, the battle formation's light curtain would ripple and undulate.
Up till now, Lingyun and Ling'er still knew that these Devil Bats were controlled by the Devil Tree in order to restrain and consume Ling'er's spirit energy.
This caused Lingyun's heart to sink. It wasn't because the Demon Tree's plan was useful, but because it could control the Demon Bats.
If there were any other magical beasts in this dark forest, whether they were large or strong, it would not be good news for them.
The Demonic Bats were weak, so they could still help protect Ling'er. If there were any Magical Beasts above the Martial Master realm, they would not be able to help her. They could only watch helplessly as Ling'er was distracted with protecting them.
However, to their relief, not a single magical beast came after a long time.
A quarter of an hour later, the ground around the Nine Palace Battle Formation was covered with broken black vines and the corpses of magic bats, just like the dead leaves.
The light of the Nine Palace War Formation was no longer as bright as it was before. Instead, it was becoming dimmer and dimmer. The formless light screen was crumbling, constantly trembling, as though it would break at any time.
If this continued, the shield would shatter before they could destroy the horde of Devil Bats. Considering the level of their cultivation bases, without the protection of the shield, the outcome would be obvious.
Ling'er was anxious as well. However, she had no other choice. Once she helped Lingyun and the others, it would be equivalent to falling into that crafty trap of the Devil Tree, allowing it to succeed.
