Breaking through the Space Wall of Nine Domains World was not actually impossible, so long as Xu Zimo put in the effort.
But the problem was that the Heavenly Dao had its own rules.
Traveling from the small world of Yuanyang Continent into the greater world of the Nine Domains was permitted.
That was why every generation of Great Emperors was qualified to ascend.
Yet returning from a greater world to a small world was forbidden, and could even violate the rules of the Heavenly Dao.
The Heavenly Dao had its rules. Whoever broke them would surely be smashed to pieces.
Thus, Xu Zimo had to make complete preparations.
This was also one of the few times he would directly contend against the rules of the Heavenly Dao.
In truth, over the years, because of the limits of his own strength, Xu Zimo had never wanted to confront the Heavenly Dao head-on.
That did not mean he was afraid.
The main reason was that although his strength had risen rapidly, he was still a long way from invincibility.
Xu Zimo had always made rigorous plans for every road he had yet to walk.
What he was doing now was no different from walking a tightrope.
He could not make a single wrong step. He had to advance steadily and surely, unless enormous gains made the risk worthwhile.
Once he entered the Enlightenment Realm, Xu Zimo would wage a decisive battle against the Sacred Court. That would be his first step.
After completely eliminating the dangers within the Nine Domains, he would gather all his strength and fight the final battle against the Heavenly Dao.
To be honest, no one had absolute confidence in victory.
After all, no one knew just how powerful the Heavenly Dao truly was.
Even the Heaven-Slayers
