Take Wan Fayi for example, his strength had reached a limit at the Supreme Strong level, and he was only a step away from the true combat power of a True Immortal. However, after arriving in the Myriad Laws Realm and attempting to ascend again, even he was by no means invincible.
Even when facing other Supreme Overlords one-on-one, he feared no one; but faced with several, or even a dozen, let alone several dozen Supreme Overlords joining forces against him, he would have no choice but to bitterly accept defeat.
At other times, for someone at his level of strength, even if others were to collaborate in an attempt to kill him, relying on his sharp perceptive abilities, he would have ample opportunity to escape.
