The so-called dimensional tribulation.
Is actually a plane's resistance against a mighty being from another plane.
Of course, this resistance only manifests when a certain level is reached.
Simply said.
Zhou Yu came up from the Human Clan Plane.
For the Primordial Realm, Zhou Yu is a foreigner.
Therefore, the realm itself naturally resists outsiders.
This is the very law of the Heavenly Dao.
However, this resistance has a limit.
When the outsider's strength is weak, plane resistance doesn't manifest.
Only when the outsider's strength affects the native powers of the plane to a certain extent, plane resistance appears.
And when Zhou Yu stepped into the Integration Realm, his strength had reached the limit of plane resistance.
Thus, Zhou Yu naturally sensed the Heavenly Dao's resistance against him.
Moreover, this resistance isn't just once or twice.
But as Zhou Yu's cultivation grows, the plane resistance will continuously increase.
