Lin Feng glanced at the fragments on the ground, and the arrowheads hadn’t suffered any damage, just bounced to the ground by Wind Defense.

Lin Feng was shocked! He didn’t expect such high-quality metal here. Thinking of the strength of the arrowheads in his mind, it was at least comparable to a Grade 7 Treasure.

The moment all the arrow mechanisms in the secret chamber were triggered, the massive Luminous Pearl at the center above gradually released its brilliance.

What was once an extremely dim secret chamber became bright, and the surroundings returned to their normal appearance.

"I plan to take these arrows. They might be useful in future battles."

Lin Feng said to Hua Shengmi.

"If you’re going to take them, do it quickly. Don’t blame me for not warning you if something changes later."

Lin Feng knew Hua Shengmi was concerned about him, so he said no more. With a thought, thousands of arrowheads were received into the Storage Magic Treasure.

This Storage Magic Treasure was specially crafted by Lin Feng for collecting materials.

Besides some Ice Lotus and Golden Pear Wood, there were remnants of short swords and bits of scrap metal, all top-tier refining materials.

These are either weapons of the mighty or ancient magic treasures.

Some were damaged in battle, others decayed over the endless years.

As long as they are refined again, they can be transformed into extraordinary new magic treasures.

Lin Feng had some experience with refining. He had gained many secret manuals on refining from the Star-Gazing Pavilion library.

Lin Feng planned to study them thoroughly when he returned to school and refine some treasures to his liking. Then maybe he would start a refining class at school.

For a cultivator, refining one’s own treasures is a very useful skill.

Sometimes, a good treasure can save your life at a critical moment. Other times, it can make up for a lack of cultivation, allowing a cultivator to defeat stronger opponents.

After collecting the treasures, Lin Feng summoned his Demon Suppressing Sword and swiftly cut a large gap in the stone door blocking the entrance. Lin Feng walked through the gap, gradually leaving the place behind.

At the moment Lin Feng left the secret chamber, a figure appeared in front of the gap Lin Feng had cut with his Demon Suppressing Sword.

Carrying a massive axe on his back, the dark light on the axe seemed even darker than the tunnel, making it particularly noticeable.

Then this figure followed Lin Feng inside.

Lin Feng found himself alone in the main hall of the Stone Temple, which was brightly lit, revealing a set of chimes capable of playing various beautiful tunes.

It seemed like a place for holding ceremonies in the Stone Temple, with a dried-up trough, suggesting that a gentle stream once flowed in from the walls, a special decorative feature.

Beside the trough was a road paved with layers of sturdy stone slabs, eroded over millennia, now rough and uneven. Strings of crystal pendants made of ice silkworm silk still hung from the ceiling, emitting a radiant glow.

The walls here held many light fixtures, though not using candles or oil. Each fixture housed a white light source, a Second Grade Spiritual Treasure quality Star Stone, essentially a spiritual treasure level Luminous Pearl.

Such a small Luminous Pearl, like a fluorescent lamp, illuminated the room without any power source, able to shine for tens of thousands of years without extinguishing.

The palace walls were adorned with exquisitely ancient light fixtures, not containing candles, but these small Luminous Pearls. They beautifully decorated the palace while providing excellent lighting—a perfect combination.

Without further ado, Lin Feng thought that school would never need candles or oil lamps again. They wouldn’t need to extinguish lights to save energy. With these tiny Star Stones, just one could keep an entire room bathed in perpetual light at night.

This palace likely contained several hundred fixtures of this kind.

Lin Feng directly took a Star Stone from a fixture and stored it in his Storage Silk Bag.

"Such a good treasure brought back would be very useful."

Lin Feng was just speculating, knowing these luminous pearls could be used to light the surroundings of a camp, especially near important posts needing extra illumination.

Along the way, Lin Feng collected anything he thought useful for the camp into his brocade bag, though it seemed like an instant in thought.

Lin Feng didn’t get greedy, calculating that there were at least four hundred pearls. After taking two hundred, the walls dimmed as two hundred lights went out, but it remained particularly bright.

Lin Feng figured since he hadn’t taken everything, perhaps he wouldn’t trigger any traps. As he expected, even after a quarter of incense time, no mechanisms were activated.

During this period, Lin Feng carefully investigated everything here, while scenes from the Streamlight Recall class replayed in the palace.
