Gu Mang lowered her head to glance at Gu Si who was right at her waist. She took out her hand from her pocket and pressed his head.
"I see now. It's not a school but the army."
Gu Si drooped his head low and said softly. "I see now."
Gu Mang half-squatted and looked into his eyes. "Gu Si, you are a genius, but you're too weak. If something happens, I can't guarantee I'll be able to protect you."
"I know." Gu Si's eyes were red and misty. "But I don't want to leave you."
Gu Mang hugged him and patted his back gently. "Be good."
Gu Si sniffled, and raised a hand to wipe away his tears. He gritted his teeth and said emphatically, "Sis, wait for me to come back. I'll beat whoever dares to bully you!"
Gu Mang laughed, holding his small shoulder. "Who dares to bully me? They're not afraid of the brick in my hand?"
