At this moment, Ye Feng had no time to care about what others thought, because he was feeling quite tense himself.
After all, comprehending Space System Rules was not his ultimate goal; he wanted to use these Higher Rules to grasp the Supreme Rule.
And to achieve that step, the first thing he had to do was to fuse them together.
Previously, when Ye Feng had realized the Spatial Cutting Rule, he had already tried to fuse the three rules together but had not sensed anything.
What Ye Feng was attempting now was naturally the fusion of four rules.
By this time, the Spatial Cutting and Rule of Space Tear had already fused together. Ye Feng took a deep breath, brought over the Space Transfer Rule, and then merged it as well.
The fusion of three rules would undoubtedly be more difficult, which led Ye Feng to make more adjustments.
However, he already had experience in this area, so it took him only about half an hour to successfully complete the fusion.
