Douluo Dragon King: Starting Abyss Invasion

Tang Xiayan traveled to the Douluo world, and it was still five hundred years before the story of the Legend of the Dragon King. On the day of awakening, he didn't even have a martial soul, but the sister he picked up awakened a martial soul that he had never seen before and was born with full soul power. Logically speaking, Tang Xiayan would spend an extremely ordinary life in Douluo Continent, but on his way home, a crack in the abyss suddenly appeared above the city. After that, Tang Xiayan finally awakened his martial spirit, but he also became separated from his sister. So he embarked on the process of becoming stronger and looking for his sister, but he met Gu Yuena who woke up early for unknown reasons. Why did she come? ... This is the biggest crisis that Douluo Star has ever faced, and it is also a period of history that is destined not to be remembered.
