"Boom!"
Violent waves of air exploded outward. Xu Yang's disheveled hair flew as flecks of golden light appeared on his body and swiftly spread over him. In an instant, he was golden from head to toe, as though cast from gold.
It was the defensive technique he had not used in a long time: the Golden Astral Skill.
At his current realm, a marrow cleansing technique like the Golden Astral Skill no longer had much power, but it was not entirely useless. His aura rose a little, and he looked even more powerful. Vast strength surged through his arms as he charged forward. The scattered power of heaven and earth gathered around him again, and the Giant Tortoise's radiance blazed.
Xu Yang could feel that he could become even stronger and unleash even more powerful attacks. A terrifying force still lay dormant within his spirit bone, but he had no Spirit Bone Martial Art with which to unleash it.
Or rather, his development and control of his spirit bone were still so weak that he could not unleash that force without the aid of a Spirit Bone Martial Art.
This was also why Yu Hong thought so little of him as a Spirit Bone Prodigy. If a Spirit Bone Prodigy did not even know a Spirit Bone Martial Art, how could he unleash his greatest strength?
His fist tore through the air with the force of a collapsing mountain, and thunderous sounds rang through the hills.
Xu Yang sprang forward and was fighting Yu Hong again in an instant. Rocks kept exploding, and shock waves swept outward one after another. Wang Heng barely managed to retreat beyond the range of their battle before collapsing painfully to the ground, staring in horror at the scene of mountains crumbling and earth splitting.
