Since Bai Long decided on what to do, all he needed to do next was think of how he would actually do it.
This was also when Bai Long after registering the mission under his name went to the Scroll Palace.
With the Ring of Darkness on his finger, Bai Long would never have to worry about not having enough techniques to train in.
Therefore, the reason he went to the Scroll Palace wasn't because he was searching for techniques to train in. Instead, it was because he wanted to compare the techniques inside his Ring of Darkness with the techniques that were there inside the Scroll Palace.
Showing his identity which allowed him access to the Scroll Palace once every month, Bai along learnt that he could stay as long as he wanted inside the Scroll Palace but could only select one technique.
At the same time, he wasn't allowed to try and learn the techniques while inside the Scroll Palace and could only read the gist of them.
