I, the Intern, Was Stolen from Me by the Golden Lion at the Beginning!

Ivan traveled to the world of One Piece and became a new member of the Rocks Pirates during the Rocks era. Fortunately, the system was activated, and Miyamoto Musashi was given Miyamoto Musashi's second-class two-sword swordsmanship at the beginning. In order not to become cannon fodder, Ivan practiced hard. Yet on the other side. The Golden Lion, who had been stuck in a bottleneck for a long time and could not break through, suddenly appeared in front of a light curtain, and in the light curtain was Ivan's figure! "Is this kid a new student? Why is his swordsmanship... So superb?!" The more Golden Lion watched, the more shocked he became. He tried to follow the practice, and after just a moment... He made a breakthrough! "Is this the swordsmanship that a new student should have?! This is also... Wait, his swordsmanship has actually improved?! It's actually more sophisticated than before!" The breakthrough of the Golden Lion allowed Ivan to obtain a new reward: the second-class secret of the second world. It's not just him, more and more big guys are joining in... They are all trying to steal his skills! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
