This is the Han style's strategy

The heart was the center of qi and blood, and the internal organs were all vital parts. Even if a divine Lord or divine Emperor was hit, they would be greatly affected in a short time, such as their combat power being weakened, their qi and blood insufficient, and their divine power difficult to mobilize.

Therefore, once many experts were injured, their combat strength would weaken.

Han Feng's heart-killing sword was specifically used to attack the heart.

The heart-killing sword Qi exploded and went straight for the heart. Once it hit the opponent's heart, the opponent's strength would be greatly weakened in an instant.

Unfortunately, he had met Lu Ming.

Lu Ming did not have any so-called vital points now.

Every cell in his body was the center, the core.

Therefore, Lu Ming's heart was pierced by the celestial eradication sword Qi, but he was not affected at all.
