Zeru did not withhold his techniques.
Now that the Sword Saint knew that this fake Jin had some knowledge of his sword techniques, he had to make sure that he does not reign freely throughout this world. His sword techniques were made in memory of his dearly departed wife and it was not for any Tom Dick or Harry to swing it whenever he liked.
If it was for Jin, he did not mind at all, especially after what he did to aid him and his wife to unite once more even if it was for a brief moment. But this imposter… "You shall not sully the Lotus Techniques."
"Oh, before we forget. This clone can not only use techniques your "Jin' were capable of but also the ability to learn and adapt. We cannot have the past owner to come back from his vacation and find that there is nothing new this puppet can provide, right?" The fake System echoed their thoughts outwardly to everyone within the Dungeon Maker Arena as the imposter Jin returned the attack against Zeru.
