If the patients had bradycardia, cardiac stimulants would undoubtedly help to enhance myocardial contractility, so it made sense to have some adrenaline as stand-by.

Yuan Huan was well versed in medicine, so he stopped being suspicious of Huo Yulin. Also, Prof Gao happened to speak to him, so he stopped speaking to Huo Yulin altogether.

Huo Yulin sighed in relief when Yuan Huan stopped probing.

Before long, the assistant came back with two doses of cardiac stimulant.

Huo Yulin narrowed his eyes and took the cardiac stimulant from the procedure assistant and placed it in the surgical tray beside him. When they were ready, Prof Gao proceeded with the surgery with Huo Yulin as his assistant.

When Huo Yulin cracked open the patient’s chest, he could suddenly sense pain in his chest the moment he exerted force on his hand.

Huo Yulin’s hands trembled slightly, but it was almost unnoticeable. He quickly tightened his grip on the surgical knife and continued operating.

Yuan Huan was the only person looking, so no one else noticed anything amiss with Huo Yulin.

Before long, he had cracked open the patient’s chest.

Huo Yulin frowned when he saw the brown clumps in the patient’s organs.

The experiment subject was suffering from multiple organ failure. Since there was no saving him, he volunteered to be an experiment subject.

In theory, the analysis solution was only able to forcibly change the human genome in the subjects and change them physically.

It seemed as though the patient’s organs were rotting from the inside. Even the analysis solution was unable to cause such side effects in the experiment subject.

Huo Yulin could not help feeling puzzled.

Even though it seemed strange, he did not have the energy to dig further.

As the surgery went on, the pain in his chest aggravated. He could even sense his wound gradually splitting open.

Beads of sweat oozed from his forehead trickling down his face. When his assistant saw the sweat, he hurriedly took a towel and wiped it for Huo Yulin.

His colleague noticed the pallor on his face and asked softly. “Huo Yulin, are you okay?”

Huo Yulin was wearing a mask, so it was impossible to look at his face closely. He shook his head and replied. “I’m fine.”

No one paid any attention to their conversation since Prof Gao and the others were busy studying the data.

They simply needed the experiment subject for data to learn from their mistakes.

Before long, another hour had gone by.

Huo Yulin leaned against the surgical table. No one had noticed his legs trembling. His hands were moving mechanically by sheer will.

His chest and back were very damp. Fortunately, he was wearing an extra layer of protective gear. Otherwise, it was impossible to miss the dampness.

Roughly 20 minutes later, the surgery was finally over.

Huo Yulin was unable to carry on anymore. After completing the last stitch, he put down the surgical tools. When he put away the surgical tools, his hands grazed the surgical tray containing syringes casually.

Huo Yulin exchanged a few words with Prof Gao before he went to the changing room. He walked with his back straight and looked completely normal.

Since the professors were discussing the results of the surgery, no one paid attention to Huo Yulin, including Yuan Huan.

Huo Yulin entered the changing room and locked the door behind him. He leaned against the door and felt exhausted. In his right hand, he was holding a syringe full of cardiac stimulants.
