Douluo: After Rebirth, I Took Back the System

Previous life. Lin Feng traveled through Douluo, thinking that there was no system, and cultivated to a titled Douluo on his own. But the strange thing is that Tang San's soul power has always been one level higher than his, no more, no less. Until his death. Tang San came over and asked him mysteriously: "What is the system?" This moment. Lin Feng was shocked to realize that perhaps his system had bound Tang San by mistake. It's too late to complain and be angry. Live a new life. This time, he wants to take back his system! Known 1: The system is [your soul power is always one level higher than the opponent's] system. Known 2: When Tang San had no time to obtain the spirit ring but had to break through to the next realm, the system would automatically generate a ten-year spirit ring. Known 3: The system will discover the binding error twenty years later and return on its own initiative, but Tang San will kill him in advance to prevent the system from returning. Then, the truth is known and the plan begins.
