Boss Zheng's gaze

In just over a day, Zheng Ren had almost used up all of the system's training time.

Separation of the liver was not something he needed to practice. After he got used to it a few times, he threw it aside and ignored it.

Professor moriyu Ichiro was only a master level spellcaster, and now boss Zheng was already a peak level spellcaster, so there would be no problem with liver surgery.

Zheng Ren's focus was still on his heart.

He tried repeatedly, but his main focus was on the anesthetist. When problems were discovered in the system's operating theater, they would go out and think hard, communicate with old he, let big Chu and small Chu experiment, and explore little by little.

As time flew by during the surgery training, Zheng Ren's eyes turned red. His gaze became deeper and more solemn.
