Even though he could defeat the Starlight Demon, it was by no means easy, in other words, he was not a match for this guy.
Even if he added others, they might not be able to match this person.
The current situation might even be reversed; it wasn't them who made the opponent admit defeat.
Cao Zhen didn't strike hard, he even deliberately sent the Starlight Demon flying further away, after all, he had no conflict with these people from the Senluo Demonic Sect.
At the same time, he hoped these people from the Senluo Demonic Sect would leave quickly.
If possible, he also wanted others to mistakenly think he was from the All-encompassing Sect, but if he really was from the All-encompassing Sect, he would definitely make these people from the Senluo Demonic Sect admit defeat.
If the opponent did not admit defeat, it might lead to a desperate fight, resulting in death.
