章 675: Why?

Li Shiyu looked at Yang Mingzhi and Liu Furong. He nodded and got up. He went to the cabinet at the side and took out two bottles of agent. Then, he took two syringes and sucked up the agent.

"Arm," Li Shiyu said calmly.

Yang Mingzhi rolled up his sleeve. Li Shiyu injected him with the agent. He took the other syringe and injected Liu Furong.

After that, he took two ropes from the back of his table and said to Qi Long and Zhao Jun, "Have them lie on the bed and tie them up. This will prevent them from hurting themselves."

Yang Mingzhi and Liu Furong felt their hearts jumped. "What kind of agent did you give us?"

"A good one. It will let you recover in 12 hours." Li Shiyu replied calmly, "Of course, since the agent is a bit stronger, there would be more pain. I'm worried that you two won't be able to withstand the side effects of the medicine. If you hurt yourself, my precious medicine will be wasted."
