Chapter 681 How... How could this happen?

If Han Yuankai wasn't a demon cultivator and hadn't used the Bloodthirsty Great Formation, with his current strength, Lu Chen might have actually not been his match.

But unfortunately for Han Yuankai, he was a demon cultivator, and his strength mainly relied on the enhancement of the Bloodthirsty Great Formation. For demon cultivators, Lu Chen was like their nemesis.

Han Yuankai was still intoxicated with his own power, completely unaware of what he might face next.

However, after seeing the smile on Lu Chen's face, Han Yuankai felt a bit confused, knowing that his strength had reached the Myriad Laws Realm, and with the enhancement from the Bloodthirsty Great Formation, his strength was at least above the Myriad Laws Realm Fifth Layer.

Could the Sum Emperor still afford to smile under these circumstances?

Could he have been frightened into stupidity by the aura he himself had released?
