Shi Lang and Tian Jian fought inside the spatial dimension. They both were fighting like there was no tomorrow. Although Shi Lang was capable of pushing Tian Jian back, but he had yet to breakthrough the defence completely.
On the other hand, Tian Jian was about to go crazy whenever he saw Shi Lang attacking him. Every blow was stronger than the other. The psychological impact of the attacks was so great that it almost made Tian Jian pass out.
The battle did not involve only physical or spiritual aspects, but also the Dao Laws they have comprehended. With every block, Tian Jian was gaining new insights in his cultivation and the same applied to Shi Lang.
Even if the people could not see much difference in his swordsmanship, the Terran knew that he was growing stronger with every second he spent fighting with Tian Jian. In his vision, Tian Jian had become a mountain that stood tall and proud. Shi Lang wanted to slash this mountain with his blade.
