Studying Ninjutsu in the Douluo World

After traveling to the Douluo Continent, he discovered that the Douluo Continent actually still had the Sharingan Spirit. Even when they were still part of a family, Huo Xing began to wonder if ninjutsu could also be prevalent in this world. It is said that Douluo is the basement of the fantasy world. Now if we add ninjutsu, I wonder if it can be raised to the ceiling level of the basement. "This is of great research value." Huo Xing looked seriously at Zhu Zhuqing, who was lying on the operating table with a nervous look on his face.
