Douluo Check-In: Awakening Fight Break Upgrade System?

Lin Fan traveled across the Douluo Continent, started with full soul power, and became the proud son of the White Tiger Sect, the first sect in the Star Luo Empire. Unfortunately, due to bad luck, his soul power only increased seven levels in seven years, and he became a well-known waste genius. Lin Fan was confused, was this innate soul power fake? Until one day, he saw the system prompt in his mind - the host's current state, fighting spirit, third stage... Lin Fan seemed to understand that his grandma's soul-cultivating power was useless, and he seemed to have to cultivate his fighting spirit. But this is the world of soul power, how to cultivate fighting spirit? Check in, right? Since then, Lin Fan has embarked on a journey to check in all Douluo. He has checked into the Tiandou Empire Palace for two and a half years. At the request of the royal family, he joined the Tiandou Royal Team. He stepped on Shrek, punched the Spirit Hall, and won the Soul Master Competition. He had been in the Wuhun Palace for two and a half years. During this period, Bibi Dong did everything possible to lure him into joining the Wuhun Palace. When he left, he gathered all the titled Douluo to stop him, threatening to leave his body behind if he didn't join. There was no other way, Lin Fan could only fight his way out. Two days later, the news that Wuhun Palace was severely damaged spread throughout the world! Some years later. When someone asked Lin Fan, who was already invincible in the world, why he always hovered between various forces but remained neutral. Lin Fan smiled: "Have you ever heard of a trip here? I checked in for the trip, and they insisted on me joining."
