After spending an entire day constantly teleporting, Wang Chang realized that the coordinate of this world was farther than he anticipated. The only reason he did not use a Void Boat was because he was faster than it, but even with his cultivation technique, he knew that he might take a while to get there.
Not wanting to waste time, he took out a Space Treasure from his space ring, then crushed it with his bare hand. The destruction of the treasure created a large amount of spatial energy.
So, Wang Chang used this energy to support his teleportation. Previously, he could only teleport a few million light years in a single instance, not he could teleport a few billion light years.
As such, by constantly destroying space treasure and using such a wasteful method, Wang Chang arrived at his destination in just six days instead of 6 months.
