Unfortunately, he knew that with his current strength, without the Four Swords of Zhuxian, he simply couldn't match the two of them.
So, he left without hesitation.
There was no other choice. When Saint of Taiqing and Upper Qing Saints joined forces, it was the combination of two Innate Treasures and two powerful saints. In such circumstances, even if Mother Earth, the strongest among the saints, were to come, she wouldn't stand a chance against their alliance.
When Upper Qing and Taiqing worked together, it was no exaggeration to say they were truly invincible. Even if Di Jun Taiyi, two supremely powerful beings, were to be resurrected, they wouldn't be their match.
Continuing to stand off against the two of them here would be useless, and he might even suffer losses.
