In this world, some people are born with souls, while others have to cultivate to a certain level before they can awaken their souls. People who are born with souls are called heavenly souls. Their cultivation path will be easier than many immortal cultivators, but there will also be bottlenecks. If you break through the bottleneck, you will be invincible at the same level. If you don't break through, you will die. Lin Daoyi is a heavenly souler. Later, Lin Daoyi was involved in the war between the three races of immortals and demons thousands of years ago. After surviving, he sealed his memories in the Tiandao Sword. However, due to the breakage of the Tiandao Sword, some memories were lost. The elders of the Tiandao Sect who survived the battle also chose to hide the truth from the world. After all, in the open world, those casual cultivators who had not shown up to help might want to take advantage of the situation. It was not until Lin Daoyi took out the Tiandao Sword again that the cruel truth of that year appeared in his mind...
Intention: Invincible
