According to the Sea-Breaking Great Saint, even if it's an act, Ye Zhen must perform as if it's real.
Ye Zhen agrees with this, because everything is tied to the most important aspect of his identity.
Having entanglement with the Demon Race is not something Ye Zhen fears. From the information he obtained after performing a Soul Search on Pei Wei, it's inevitable for any martial artist, especially those with strong cultivation, to interact with the Demon Race.
In reality, on the Primordial Continent, the Demon Race is omnipresent. Many mounts in existence are from the Demon Race, though they are controlled.
What worries Ye Zhen is his origins.
Once someone discovers that Ye Zhen comes from an unknown continent, one can imagine his fate. Those crazed for military achievements on the Primordial Continent would stop at nothing to deal with Ye Zhen and find this unknown continent.
Therefore, Ye Zhen has to perform this scene with Princess Jie You.
