Douluo Dalu: What Do You Mean I’m the Third Offering’s Illegitimate Son?!

After transmigrating into Douluo, a young man sets out for Spirit Hall while pursuing his studies, hoping to uncover the mystery of his birth. Once he arrives at Spirit Hall, the truth about his parentage leaves him reeling. What do you mean, I’m the illegitimate son of the Third Offering and Elder Ling Yuan?! When the fog lifts, the young man will stop at nothing to destroy Shrek and protect his two reckless parents! P.S. One female lead. There is a System, but it won't make the protagonist overpowered. It offers little help beyond identifying items.
