Dugu laoguai spread his hands flat on his knees. In his hands, there were a piece of gray and black iron, one of which was engraved with the word "Zhuan" in ancient seal script, and the other was engraved with the word "spectrum".

If Xiao Lingyu was here and saw two gray black iron pieces in Dugu laoguai's hand, he would be surprised.

Dugu laoguai frowned and kept staring at the two pieces of iron in his hand. He murmured from time to time: "what's the secret? Shifu said that you can easily practice the eighth and ninth layers of Tianjian formula after getting the chaos spectrum. It should not be a vain statement..."

Since he killed the old woman, Dugu laoguai had been studying these two gray and black iron pieces, but he almost got nothing.

"It seems that only by getting another piece can we break the mystery."

"I don't know if the boy came back..."

"If I were him, I would stay away from the narrow divine world and hide."

"The boy doesn't seem to know that he has fragments of chaos spectrum."

Dugu Aotian put away the two pieces of iron while thinking about it, and dodged out of the closed cave.

After leaving the pass, Dugu laoguai spread out his divine knowledge with all his strength, and then began to search everywhere.

Several hundred years later, Dugu laoguai, who was very patient, suddenly gave a light sigh, and then flashed away.

At the end of the blink, Dugu Aotian was at the top of a mountain, and a black light was flying here.

Before the black light came near, he stopped first.

Dugu laoguai was surprised and said in a secret way: "those Wujia troops should retreat. Why does one stay here?"

Meanwhile, Dugu laoguai also strengthened his divine sense and searched around carefully. He was worried that there were other strong black armor nearby, and he was not in a hurry.

However, at this moment of hesitation, Dugu laoguai found that the space around the strong black armor in the distance suddenly fluctuated, and then a golden light suddenly appeared.
