The colonel looked at Liu Si, whose face was calm, and flexed his muscular arm through his sleeve:
"Come on, try your strength."
"Then be careful, sir."
Liu Si did not refuse, and their seemingly similar palms grasped each other and began to exert force simultaneously.
Just seven or eight seconds had passed when a ferocious look that the colonel couldn't suppress appeared on his face, and Liu Si promptly let go upon seeing this.
The colonel stretched his almost numb hand and asked with some disbelief:
"How much strength did you just use?"
Liu Si answered truthfully, "Around thirty to forty percent."
The other soldiers behind inhaled sharply. The colonel had previously been renowned for his physical strength, and yet he was firmly suppressed by a mere thirty to forty percent of another's effort.
On the other hand, the people from the security bureau were only slightly surprised, knowing more than the others.
