Chapter 321

While dodging the attack, Li An kept observing the movements of the Chaos Star Demon; finally, he discovered that its head was its weak point.

"Hmph, found it!" Li An snorted coldly, took a deep breath, gathered the Star Power to its utmost limit, and unleashed his strongest move: "Star Annihilation Shatters the Firmament!"

His figure turned into a beam of starlight, instantly charging toward the Chaos Star Demon's head, his long sword in hand carrying boundless Star Power and an aura of destruction, thrusting fiercely into the Chaos Star Demon's head.

Sensing the danger, the Chaos Star Demon tried to dodge, but Li An's speed was too fast; it simply had no time to react.

"Puchi!" A loud crash sounded as Li An's long sword successfully pierced the Chaos Star Demon's head; the Star Power exploded instantly, blasting the Chaos Star Demon's head into fragments. The Chaos Star Demon let out a shriek, its massive body began to crumble and disintegrate, dissolving into countless streams of Star Power within the Chaos Star River.

With the death of the Chaos Star Demon, the Star Power in the Chaos Star River gradually calmed down. Li An and the others also breathed a sigh of relief, their faces showing tired but gratified smiles.

"Li An, you are too amazing!" Yuigahama Yui ran over excitedly, her eyes full of admiration and affection.

Li An smiled and patted her head: "As long as everyone is safe, that's all that matters; too many dangers are hidden within this Chaos Star River, we must be even more careful."

Teacher Hiratsuka and Yukinoshita Haruno also walked over, expressing their admiration for Li An's strength.

"Next, let us continue searching for clues to counter the Sixth Heavenly Demon," Li An said, his gaze firmly fixed on the depths of the Chaos Star River.

The four set out on their journey again, exploring the Chaos Star River with utmost caution, missing no corner that might hide clues.

As they walked, an ancient Star Palace suddenly appeared ahead. The palace walls were covered with mysterious 5.3 runes and patterns, emitting an ancient and mysterious aura.

"This palace looks very unusual; perhaps the clues we need are hidden inside," Yukinoshita Haruno said, her eyes flashing with curiosity.

Li An nodded: "Let's go in and take a look, but everyone must be careful; there may be dangers within this palace as well."

With that, Li An led everyone into the palace. Inside, it was dim and damp, permeated with a stale, old air. The runes on the walls flickered with faint light, as if telling ancient stories.

They moved forward cautiously within the palace; suddenly, a stone door appeared ahead. The stone door was tightly shut, with a huge star pattern carved upon it.

Li An stepped forward and carefully studied the pattern on the stone door, discovering it was a mechanism. Following the guidance of the star pattern, he injected Star Power into several grooves on the stone door.

As the Star Power was injected, the stone door slowly opened, and a powerful aura surged out from within.
