Furthermore, the reason Sect Leader Tongtian dared do this was because he was sure his God-killing Sword Formation could not be broken even if the four Sages were to unite. His cultivation was equal to that of Laozi, Honored Lord of the Origin, and Jieyin. However, Zhunti's was not as high now that his Holy Body had been recently slaughtered. Since one of the four had been badly hurt, it would not be easy for them to break the formation.

In the Blood Sea, Minghe smiled when he noticed what had happened there. He also did not know if the four Sages could break the God-killing Sword Formation when it was refined to perfection. Actually, maybe Sect Leader Tongtian was also not fully confident of a victory. Among the four Sages of the three religions, Laozi was the most unpredictable one. Even Minghe did not know what kind of ace in the hole he might be holding.
