Infinitely Upgrade Steel Balls, They Say I Am a Rule Level?

Upgrade flow + spiritual energy recovery + single female protagonist + abnormal creatures + containment Spiritual energy is revived, the world is alienated, abnormal creatures are born out of thin air, and the world enters an era of great containment. Xu Shen, a pinball enthusiast, accidentally bound a frequently used [steel ball], which can be continuously upgraded using proficiency. Ten days after his spiritual energy was revived, Xu Shen's steel balls possessed accuracy and destructive power that surpassed that of a sniper rifle. After a hundred days of spiritual energy recovery, his steel balls can strike across continents. Some years later... [Abnormal Creature 000: Xu Shen] [Rating: Unpredictable] [Note 1: He has some kind of unobservable attack method. If he bends his thumb to make a "bounce" action, the method will be triggered. [Note 2: He behaves "friendly" most of the time and is often more patient with younger women. If you encounter a Destruction-level threat, you can try to seek help] [Note 3: Do not make a "bounce" gesture in front of him in any form. He will pull you into some kind of game. The consequences of failure are currently unknown!
