This pressure comes from the power of that middle-aged man.
The strength of this middle-aged man has already reached its limit. His power is so overwhelming that his physical body seems unable to contain it. The immense power radiates out, affecting everything around it.
This pressure stems from that.
The realm of this middle-aged man is still at the half-step Heavenly Human Realm, but upon seeing him, Chu Fengmian felt the presence similar to when he first encountered Long Qianjue.
This young man is also someone who can attempt a breakthrough to the grand calamity at any moment, elevating to an immortal state.
However, Long Qianjue suppressed his power due to injuries, while this middle-aged man deliberately used a secret technique to conceal his strength, thus delaying the descent of the grand calamity.
This young man is precisely one of the powerhouses whom Chu Fengmian sensed when he first arrived at the Sea Sacrifice Sect.
