Even breathing hurts

Anyway, when he used the secret appraisal technique now, he no longer needed to shed any blood, which resulted in Song Shuhang being a lot more liberal in using it.

Unlimited tries for free~

After a while, a small wound appeared on the smokey Song Shuhang's arm.

If a wound of this degree were to appear when he was in his normal state, it would merely be a small scratch on his arm. With Song Shuhang's current physical strength, the wound would heal before blood could flow out of it.

Song Shuhang felt disappointed.

He didn't even need to look at the results of the appraisal to know that this little experiment had failed.

What useful information could he have possibly gotten from appraising something that only cost him such a small price?
