The number one defense post was located in the capital of Datong, Zhongzhou.
Originally, the strength of the number one defense post was almost the same as that of other places, but as the cross-realm passages were restored, its power became extremely formidable.
In ten years' time, the situation had become worse than imagined.
Focusing his power was already the best choice.
Huangtian hadn't closed his eyes in sleep or sat down to rest in ten years.
Over the past decade, his spirit had been highly concentrated, not daring to slacken in the slightest because he was very clear that once there was any relaxation, what lay in wait for Datong might be destruction.
Even now, with this situation, regardless of his vigilance, the outcome would likely be the same.
The contingency plan prepared by the master couldn't allow him to face three Eighth Realm powerhouses at the same time, especially when one of them was at the pinnacle of the Eighth Realm.
