Space Lock

Hei Gou looked at Xue Wei puzzledly, but he did not say anything. Instead, he gathered Qi within his palm and struck it directly into the barrier.

A boom resounded in the surrounding area, and the barrier shook drastically. While it did not dissipate, the glimmer of the barrier was much less than before and much easier to see through. Clearly, the attack had caused severe damage, and Hei Gou had not even used a martial art skill, all he did was gather Qi in his palm and strike it.

Frowning, Xue Wei looked at the formation, and Hei Gou tried attacking with one more palm attack. The formation instantly shattered, and the stones and ores used turned dull as the energy within had been used up trying to maintain the formation.

Xue Wei sighed as he felt the pain in his heart for wasting so many precious materials, but he began creating the same formation again.

"Try now," he said, and this time the formation lasted four strikes from Hei Gou before it collapsed.
