The difference between Chen Fei and a true Rule Integration Realm might just be that Chen Fei cannot sustain combat, as the essence, energy, spirit, and soul within him could not support the massive consumption required.
Also, although the attack power of Chen Fei in that state reached the necessary level, the precision of attack control still had a significant difference compared to the true Rule Integration Realm.
This difference did not show when Chen Fei faced opponents in the Sun Moon Realm.
However, were Chen Fei to truly face someone from the Rule Integration Realm, he would be at a disadvantage from the first strike.
Within ten moves, Chen Fei would be defeated.
Other warriors at the Sun Moon Realm, when facing the Rule Integration Realm, were killed in a single strike.
Chen Fei managing ten moves could already be considered impressive.
