Jest emerged from the Dao Realm a different person.
He spent 20 years in an enlightened state, still inside the Sword Valley. When he woke up, he felt like he had what it took to surpass all else. He felt that his time to rise had come, so he left and began to walk his path.
However, 20 more years passed, and he hadn't even moved a single step on his sword path. Aside from becoming the best Sword Saint there is, he hadn't made any progress.
"I clearly know what has to be done, but why am I not making any progress even after 20 years?" Jest wondered. He didn't know why.
The plan was to reach the peak, yet even after such a breakthrough, he made no progress. It was a blow to his ego as a swordsman.
But Jest was a patient man. He had been patient for years, so he could be patient again. Thus, another ten years passed, but still there was no progress.
At this point, his patience was wearing thin, so when he heard someone had become a sword emperor, it was a blow to him.
