The Useless Boy's Counterattack System

In Xuan Cang Continent, there is no history of dynasty changes, and only the Monk Era is used to count the years. As everyone knows, the calendar commonly used in mainland China is called the "Xuan Cang Calendar". The beginning of the era was not the founding of a certain dynasty, nor the ascension of a certain emperor to the throne, but an old event that shook the heavens - Three thousand seven hundred and twenty-one years ago, the supreme being who once controlled chaos and was revered as the "Lord of Chaos" took his seat in the extreme north. When he died, he dispersed his power to the heavens and transformed his origin into countless inheritances, spreading them throughout the world. From that moment on, the spiritual energy of heaven and earth disintegrated and became thin like the ebbing tide. High-level monks have since disappeared like phoenix feathers, and no one can touch the peak of that year.
