After obtaining the Fifth Grade Cloud Bamboo Arrow Formation, Lu Xuan could not suppress his curiosity and went outside the Cave Mansion.
Surging Spiritual Power poured into the Array Plate, and formation flags flew toward different positions along the edge of the Cave Mansion. Spirit patterns swam across the flag surfaces, then vanished in the blink of an eye.
A heavy sea of clouds soon appeared outside the Cave Mansion. As the cloud sea churned, strange bamboo stalks towering into the clouds appeared and disappeared, with the faint sound of rustling drifting over.
"Double protection from a Fifth Grade Array Formation. This should ensure no Evil Spirits or Demon Worms invade the Cave Mansion and damage the spirit plants."
A satisfied smile appeared on Lu Xuan's face.
For the last Arrow Vine, seeing that it was not far from maturity, he simply used Azure Wood Source Qi to ripen it.
He had accumulated quite a few Spirit Gathering Grass Orbs now and could replenish his Azure Wood Source Qi in time, so he used it with complete confidence.
After harvesting the Arrow Vine, Lu Xuan gently touched the White Light Orb that had quietly appeared.
Countless points of light turned into the phantom of a small white arrow and instantly poured into his body.
Harvested one Fourth Grade Mutated Arrow Vine. Obtained Fifth Grade Treasure, Nailhead Arrow.
As the thought flashed past, a short, pitch-black arrow appeared in his hand.
Faint Black Qi coiled around the surface of the small arrow, slowly swimming like a slender black snake. The arrowhead seemed to be nailed into a translucent human face, whose features were blurred and impossible to make out clearly.
His mind focused on the pitch-black arrow, and a stream of information surfaced in his mind.
Nailhead Arrow, Fifth Grade Treasure.
