Jiang Yao bowed her head and donned her mask. She nodded and replied, "Yes." Then, she yelled out to Gu Haoyu, who was two steps away. She said, "I still have my old rules. No one is permitted to approach or enter the operating theater before I am done. I require a quiet working environment and cannot be interrupted by anyone."

Gu Haoyu asked no further inquiries. He agreed with a nod. Even though he did not bring security, he personally stood guard at the operating theater entrance and did not allow anyone to go near.

Jiang Yao was stern. She did not let anyone doubt her talent, and she did not let anyone affect her. Gu Haoyu had a lot of faith in Jiang Yao's medical abilities. He had seen the way Jiang Yao fought for her life with the Grim Reaper. He had witnessed her refusal to give up, and she always takes her responsibilities seriously.

Jiang Yao walked inside the operating room. That location drew a lot of attention since Jiang Yao was responsible for a case that rendered the hospital relatively helpless.

When the hospital manager noticed the situation, he summoned the hospital's security personnel to assist Gu Haoyu in guarding the area.

Although they did not know the young female doctor performing the surgery, they knew she was someone who could get Second Young Master Gu and Miss Luo to watch over her. They also knew that the hospital could not afford to offend her.

The pediatricians and doctors from various departments in the hospital were there after they heard about it.

Everyone who took part in the child's physical examination was on the same page about it. Initially, the hospital had prioritized arranging for a pediatrician to check on the child because he was accompanied by Second Young Master Gu. However, ever since they got the results back, the pediatrician had a headache and transferred the child to a professional hematologist. Those specialists were still debating feasible methods that could be used to prolong the child's life before gradually treating him.

They were still discussing it and did not have the time to come to a conclusion. They did not expect someone to suddenly say that the child would be operated on in an hour and suddenly take over the child's treatment from their hands.

Those doctors were concerned about the plan that the young female doctor would use to treat the child. After all, the child was only a few months old, and they could not use most of the drugs on him. That was their most significant challenge.

Five hours in the operating room was as uncomfortable as ten hours in the waiting room. After she brought the baby into the system space, Jiang Yao activated the blood purifier and began to repair the child's heart.

The blood purifier was very useful. Jiang Yao needed to draw the blood flow from the child's body into the purifier. Then the system would automatically clean the blood in the purifier before returning it to the child's body.

That was the same as recirculating the child's entire body's blood through the purifier.

Jiang Yao could not neglect a single element of that surgery. Jiang Yao had to observe the data on the purifier every minute to track the patient's physical condition.

Jiang Yao had forgotten how much time had passed when she became preoccupied. Lu Xingzhi, who was in the army at the time, returned home and glanced around at the quiet and cold house. He retrieved his phone and dialed Jiang Yao's number, but Gu Haoyu had answered it. Jiang Yao had left her phone with him before she entered the operating room. She had said that the surgery would take a long time, and when Lu Xingzhi arrived home from training, he did not see her. Gu Haoyu assured him that she would contact him. That guy appeared to be checking up on her, as one would expect.
