On the other side, Lu Yu began to deal with the Tianling Crystal here.
His three knives all need such Tianling Crystal to repair.
These things are more precious to him.
"The Beidou Tianzong's storage space should be able to hold these Heavenly Spirit Crystals," Lu Yu glanced around.
Although the quality of the Sky Spirit Crystal is not as good as that of the Dragon Spirit Crystal, quantitative changes lead to qualitative changes. These days, the Sky Spirit Crystals mixed together are enough for Lu Yu to repair the magic weapon.
As soon as the storage bag was opened, countless Heavenly Spirit Crystals fell into Lu Yu's hands.
Suddenly, wisps of faint black smoke flashed in the air around him.
Lu Yu stopped immediately and noticed the elusive black smoke in the air.
"Demon energy?" Lu Yu's eyes narrowed.
Soon after he stopped moving, the demonic energy around him gradually began to become thinner.
However, Lu Yu had already sensed the direction from which the demonic energy was coming.
Lu Yu felt a bit familiar with this kind of demonic energy, as if he had encountered it in his previous life.
"You... come here..." An intermittent voice transmission fell into Lu Yu's ears.
Lu Yu's eyes narrowed and he followed the source of the sound. He immediately discovered an unexpected cave.
Stepping inside, it was pitch black inside, but Lu Yu could still see clearly with his eyes.
"I'm here..." The voice seemed very weak.
Lu Yu approached and saw a withered altar in the cave, surrounded by dust and blood.
A bearded man sat on the altar, his long hair beginning to change color due to dust accumulation.
"You have a good soul. I need you to do me a favor." The man said in a message.
Lu Yu glanced at the man up and down, frowned and said, "Draw the ground as a prison?"
The man's eyes lit up, he raised his head with difficulty, and stared at Lu Yu: "How do you know!"
Lu Yu sat cross-legged in front of the man: 'Tell me, you would rather suppress this place forever than leave far away. What exactly are you suppressing down here?'
The man stared at Lu Yu: "The existence below is a demon that you can never imagine. I have been trapped for too long and I have no strength. Can you help me thrust this sword into the thing over there?
In the cracks.”
It was an ancient bronze sword soaked in blood.
Lu Yu didn't answer and shook his head: "This contains your true blood. In your condition, if you use this sword to seal it, you will die."
"Hahaha...cough!" The man laughed and coughed up blood, "I've done my duty of exterminating demons, I'm done with it. Just die, what's there to care about!"
There was a trace of sadness in the man's voice.
The man sent the bronze blood sword in his hand to Lu Yu again: "Go ahead and stab this blood sword in. As long as I can suppress that demon, my death will be considered worthwhile."
Lu Yu didn't even look at the bloody sword in the man's hand, and shook his head: "I'm afraid your sword is not very powerful anymore. Even if it can be sealed for a while, it cannot be sealed for a lifetime. If my prediction is true, this sword will definitely be sealed within a year."
fracture."
Lu Yu looked directly at the man: "If you believe me, tell me what's sealed below, and I can help you."
The man smiled bitterly and said: "It's useless. If the ancient demon appears, let alone this star, even the entire star field will not be spared."
Ancient Demon!
A scene of interstellar melee instantly appeared in Lu Yu's mind.
Groups of ancient demons appear, countless monks have fallen, and even the powerful Tao Lord will die without a burial place if he is not careful.
Lu Yu's face suddenly darkened: "You can't seal the ancient demon. Who asked you to guard this place?"
The man raised his head arrogantly: "My master, the title is to seal the demon!"
