Martial artists from Demon Tao are mostly not of good nature, and they are often petty.
When the Great Celestial Demon Lord was initially killed by the Emperor of Mankind, his first act upon resurrection was to seek revenge against the descendants of the Emperor, demanding some form of retribution.
As for Lu Potian, who had been imprisoned by Shaolin Temple for centuries and had his martial arts crippled, being oppressed under the Demon Suppression Pagoda like a dog, you might see Lu Potian usually acting casually, but Su Xin knew how deep his resentment was.
Given the chance, Su Xin was certain that Lu Potian would eradicate the monks of Shaolin Temple in the most brutal manner possible.
Now, hearing Su Xin was preparing to take action against Shaolin Temple, even the potential alliance with Brahman Realm did not make Lu Potian fear.
He had some understanding of his nominal junior brother by now; Su Xin would not make a move without absolute certainty.
