Chapter 688 The Mystery of the Copper of the First Mountain

"Not bad! It's Xuanyuanjian!"

Tianleizi's dull and thunderous voice resounded in the courtyard.

The disciples of the Dao League took a deep breath, and the shock in their eyes could no longer be concealed.

"It turned out to be the material for casting Xuanyuan Sword! This is a legendary treasure!"

"Hey... unimaginable! Ye Yu actually took out the legendary ore!"

"The Xuanyuan Sword is the sword of the emperor's way in the legend of the Guo Kingdom! And the bronze ore used for casting the Xuanyuan Sword is definitely the best in the world!"

"How can such a legendary treasure come into existence here? Could it be that this ore is not the ore from which Xuanyuan Sword was cast in the legend?"

Although the eyes of the Dao League disciples were full of shock, they still had some doubts and confusion.

The sword-casting material Ye Yu took out was really astonishing!

Tianleizi took a deep breath when he heard the words, walked over to the bronze ore again, and leaned over to examine it carefully.

After a long while, Tian Leizi shook his head and sighed, "Hey! Please forgive me, I really can't tell whether this is the legendary bronze of the first mountain!"

"I wonder if fellow Daoist Ye Yu has a way to distinguish the mystery of this mountain copper?"

Tian Leizi looked at Ye Yu and asked aloud.

Ye Yu walked to the bronze ore and flicked his fingers.

The ore made a crisp sound of gold and iron symphony.

"If you want to distinguish the copper of the first mountain, it is difficult to distinguish it with the naked eye!"

A smile appeared on the corner of Ye Yu's mouth, and then he said, "There is a way!"

Tianleizi's eyes lit up, "What can I do?"

"Use mental power to detect!"

"Mental power?" Tian Leizi frowned slightly, "Unfortunately, Pindao is only a sixth-grade dandan martial artist. If he wants to use his mental power to detect ores, he is too weak!"

"Let me come!"

Li Wuzhen stood beside Ye Yu and said aloud when he heard the words.

Tian Leizi's eyes lit up, "A fellow Daoist will definitely be able to perceive the mystery of the ore!"

Li Wuzhen walked to the bronze ore and stood silently.

hum!

His eyes were slightly closed, and an invisible wave swept out from Li Wuzhen's eyebrows, covering the bronze ore.

Deng Deng Deng

Suddenly, Li Wuzhen opened his eyes, his eyes filled with extreme shock.

"This..." Looking at the bronze ore in front of him in horror, Li Wuzhen was so shocked that he couldn't speak!

Tianleizi looked at Li Wuzhen and asked anxiously, "Daoyou Li, how is it? Is this copper ore really the copper of the first mountain?"

Li Wuzhen took a deep breath and forced himself to calm down.

Nodding slowly, Li Wuzhen said in a deep voice, "That's right! This old man guarantees with the dignity of a warrior, this is definitely the copper of the first mountain!"

Tianleizi's eyes were even more eager when he heard the words, "Could Fellow Daoist Li elaborate, what did you find after the mental scan?"

Li Wuzhen shook his head in embarrassment.

"This..." Tian Leizi's eyes showed disappointment, "Is there really no other way?"

"I can do nothing! If you want to know the mystery of the ore, you must use your mental power to detect it!"

Ye Yu on the side looked at Tian Leizi with a disappointed face, and said with a chuckle, "Does the Taoist really want to know?"

Tian Leizi suddenly raised his head, looked at Ye Yu and said in surprise, "Of course! Does fellow Daoist Ye Yu have a solution?"

Ye Yu nodded slightly, "There is a way!"

After speaking, Ye Yu looked around the disciples of the Dao League and asked aloud, "Daoist priests? Do you also want to know the mystery of this ore?"

A look of surprise appeared in the eyes of the disciples of the Dao League, and they said in a voice, "Of course, please also ask fellow Daoist Ye Yu to take action!"

Ye Yu nodded and called softly from the bottom of his heart.

"Come out, Golden Bean!"

Swish!

A golden flash swept across the void.

On Ye Yu's palm, a golden cicada appeared!
