With a thunderous boom that tore through the air, the cannon barrel fired an enormous water ball over three hundred meters wide, brimming with an utterly terrifying aura.
Watching this scene from White Cloud City, Ling Pengyun's brows immediately furrowed.
Given the current situation, if he stood by and did nothing, the White Shadow Slanting Cloud Flying Sword would inevitably be blasted to pieces by the Demon Race's sole remaining fourth-rank grand formation, along with Wood Hidden Flood Dragon, Wind Origin Flood Dragon, and Turtle Prime Minister Old Demon.
The White Shadow Slanting Cloud Flying Sword was one of the cores of White Cloud City's City Protection Array Formation. If it were destroyed, the formation's power would surely drop by several tenths.
That would also hasten White Cloud City's fall.
Not to mention, Ling Pengyun could not bear to see such an array-implement flying sword, capable of being used in tandem with White Cloud City's quasi fourth-rank City Protection Array Formation, destroyed.
Accordingly, he drew upon thirty percent of the medicinal power of the fourth-rank Healing Pill, the White Iris Pill, which had previously been sealed within his body, and guided it into his meridians.
In the blink of an eye, the meridians that had been aching from his consuming too many Qi Recovery Pills in such a short time rapidly recovered.
By Ling Pengyun's estimate, once his meridians had fully recovered, he should still be able to consume Qi Recovery Pills twice more to restore his spiritual power, in addition to the spiritual power within his Natal Spirit Plant, the Ren Water Blue Cloud Grass, which he had yet to use.
That would give him three opportunities to unleash the Five Elements Pure Yang Profound Lightning.
*Three chances should be enough to save the White Shadow Slanting Cloud Flying
