บท 1780: Chapter 1780-the rare treasure of heaven and earth

Ling Gusong's expression was serious. He slowly released a stream of innate Qi from his hands and tightly wrapped it around the jade pendant. It was as if he was trying to break some kind of restriction. Beads of sweat dripped down his face. His long black robe had long been soaked in sweat, and his feet were wet.

Obviously, Ling Gusong had tried his best.

The light from the jade pendant in front of him flickered, like a duckweed floating in the water, rising and falling with the waves.

Suddenly, the jade pendant made a soft and crisp sound and emitted a bright light.

"I've succeeded. I've finally succeeded. " Ling Gusong heaved a long sigh of relief and clenched the jade pendant in his hand. He then said with excitement. Because he was too tired, his voice was hoarse.

"Congratulations, master." Mu Weibei, who had been waiting for a long time, saw Ling Gusong's fatigue. He congratulated him and went to help him.
