Douluo: the Wrong Person Was Tied up at the Beginning, and the Entry System Ran Away

Lin Ji traveled to Douluo Continent and just awakened the memory of his past life. The system had run away. Fortunately, he left a compensation gift package and 6 opportunities to copy entries. Lin Ji's journey in Douluo Continent begins... Tang San's entries: Son of Luck (red gold), amazing understanding (red), Xuantian Baolu (red), twin martial spirits... Get it you! ! ! With the arrival of Lin Ji, earth-shaking changes have taken place in Douluo Continent. What Lin Ji didn't expect was that after writing a One Piece novel, sailing in Douluo Continent became popular. When I was bored, I made tennis balls. Unexpectedly, tennis competition became popular in Douluo Continent. Is this fantasy tennis?
