851 The Critical Moment of the Breakthrough

The Jingdu Martial Arts Association immediately launched a carpet-like search for Qin Yu.

At this time, Qin Yu had already been in closed-door cultivation for several days.

The internal qi in his body was rapidly rising. After Qin Yu swallowed 48 golden cores, Qin Yu finally felt that he had reached the critical point of the breakthrough.

"It seems that I am about to step into the Consummate Inner Strength Grandmaster realm," Qin Yu thought to himself.

Qin Yu did not dare to delay any longer. He closed his eyes slightly and swallowed another golden core.

Under the effect of this golden core, Qin Yu's internal qi began to soar! It seemed that he was only a step away from the Consummate Inner Strength Grandmaster realm!

At this time, Uncle Guan had arrived at the entrance of the mystic realm.

He looked at the entrance coldly and then placed his hand in the air in front of him.
