After chatting with Professor Xu for a long while, Han Sen felt inspired. The materials he got from Professor Xu were also a great help to him. For the things that he hadn't been able to understand before, he managed to figure them out after reading Professor Xu's materials.
After that, when he read the Dongxuan Sutra again, he had many new understandings. Although there were still sections that he did not understand, he had a more profound grasp of the text.
Unfortunately, there were too many technical terminologies about cultivation in the Dongxuan Sutra. Because it was written a long time ago, Han Sen still found it difficult to understand and translate everything.
However, after reading the materials and asking Professor Xu some additional questions, Han Sen translated another technique.
Han Sen was able to do that because he had read Yin Yang Sutra, which Yin Yang Blast was based on.
