Hao Ren and Han Lingshi were dedicating their time to cultivation and at the same time they were balancing their roles as a teacher and the Empress, respectively. It had been three months since Hao Ren first started inscribing his comprehensions on the Halo, and he had been reading and learning all sorts of sword techniques and formations.
He did not practice the techniques that didn't suit him but he did record them in his mind and after comprehending what it was about those particular techniques that didn't suit him. He used it to refine his own skills and then inscribed them on the Halo. After three months, he finished reading almost all the big and small sword techniques from the Crescent Moon Empire.
His progression with the Halo was kept a confidential secret and thus nobody knew why he was doing it, but Ye Jian spread the word that Hao Ren had decided to practice the sword and was already moving forward to the status of the Sword Saint.
