Wan Gu was filled with shock and fury.
But he reacted very quickly. A great swarm of red, grain-like flying insects flew out from his sleeves. This was one of his commonly used methods—[Red Rust Insects]!
These insects possessed an extremely terrifying "rust-corrosion poison." Even the Demonic Essence of a Nascent Soul Demonic Cultivator could be eroded by it, and they were as fast as lightning. They also innately possessed the trait of being Invulnerable to All Laws.
The Dragon Emperor version of the Yin Nether Demon Dragon Wang Yu unleashed abruptly slammed into the Red Rust Insect shield. The color of red rust spread like ink dripping into the water surface, rapidly expanding across a large area.
Then it exploded with a boom. The bursting shock wave of force spread violently. Wan Gu was sent flying backward with a fierce jolt, crashing into a large section of wall behind the Poison Gu Grand Hall and smashing spiderweb-like cracks across it.
Agony assaulted him, and he had not even had time to catch his breath.
Then he saw a resplendent aurora arrive in an instant. Amid the dazzling glare, a streak of blood-colored blade light attacked once more. It was Wang Yu, holding the Flesh Demon Sword.
He had slashed out the perfected divine power—Blood Slaughter Heart Rend Sword!
Under the unbroken barrage of attacks, Wan Gu's mind trembled. Pitch-black ghostly mist surged out from his five senses. It was clearly illusory yin fog, yet the shapes of ants could be seen within it.
It was—[Ghost Ants]!
This Gu insect was specifically used to guard against Divine Sense and attacks on the mind, and it possessed extremely strong targeted effects. It could even invade the target's Niwan Palace and damage the opponent's soul.
Both its offense and defense were top-tier.
