"Roar!"
The Ninth Grade Beast Spirit, seated cross-legged by the pool, sensed an unfamiliar presence intruding and let out a furious roar. It shot upward like a cannonball.
Mu Chen's vision blurred. The gray-white beast shadow was already right before him.
At the peak of the Ninth Grade Sovereign level, it had, without his realizing it, grown into a mighty being on the same level as the Northern Abyss Dragon Kun of old. It was now strong enough to fight him.
Even so, he absolutely could not afford to let his guard down.
After all, this was a being on the verge of entering the Earth Sovereign level, invincible within the Supreme Realm.

Mu Chen's hand seals shifted rapidly. As black light writhed between his brows, a mysterious, pitch-black vertical eye, dark as a black hole, appeared. An ancient, mysterious aura rippled outward.
Dozens of drops of Supreme Spiritual Liquid flew from the Mustard Seed Bracelet on his wrist, burning wildly and transforming into a vast torrent of spiritual energy. The torrent poured into the space between his brows, urging his third eye to life.
The Life-Extinguishing Pupil was a Sacred Artifact—or perhaps a Low-grade Sacred Object that could grow.

As tens of thousands of drops of Supreme Spiritual Liquid poured in, the dark vertical pupil opened.
"Life-Extinguishing Pupil, Life-Extinguishing Divine Light!"
A low hum rang out. As the ghostly light writhed rapidly, layers of black halos burst from the mysterious eye, and a profoundly deep, mysterious ray shot forth.
A deathly stillness that could annihilate all things
