Douluo: I Have a History Book

(Douluo Three Dragon Kings Legend fanfic) Su Ling traveled through Douluo Continent and awakened the Seven Deadly Sins of his twin martial souls and the history book of the years (different from the role of Jackie Chan's Adventures). After Su Ling broke through to the soul master, he finally understood the function of his second martial soul's history book. Every time he broke through the tenth level, it would take him to the past timeline and complete some tasks. After he completed it ten times, he would have abilities higher than those of the God King. The first time he traveled to Tang San's time 20,000 years ago, he met Shui Bing'er from Tianshui College and rescued her, becoming the first male student of Tianshui College. This time, the mission given to you by the History of Time is to win the championship in the continent-wide senior soul master competition. This time travel allowed him to see the gathering of geniuses from all walks of life 20,000 years ago, and it also made him fall in love with the characters from 20,000 years ago. He changed history with the help of historical records. In this way, Su Ling relied on the history books to travel through the past and present, traveling backwards through time and witnessing the changes in Douluo Continent.
