Capítulo 670: Brewing Tea

The Ten-Force Annihilation Formation had been left behind in the Donghua Ancient Sect by a cultivator proficient in array formations.

Luo Yunyang was unclear why the person in question had left behind this formation, but he had a feeling that it had taken them at least 1,000 years of effort to set up this array formation.

Meanwhile, he would only have 10 years for this current mission!

Luo Yunyang could come up with several reasons why this person had been able to stay in the Mysterious Sky Great Cosmos for 1,000 years. One of the most important reasons was that this person had been afraid to receive a tougher mission.

After all, Luo Yunyang had only made use of the Intermediate Training Center. There was still an Advanced Training Center.

In the face of the Kunwu Sword Union's overwhelming assault, Luo Yunyang didn't hesitate at all before deciding to use that array formation.
