The doctor pushed the cart to the ward where Professor Yu and Professor Qu were resting. There were two special forces members guarding the door of the ward. They originally thought that the doctor was going to the ward next door to Professor Gu and Professor Yuan, but the doctor pushed the cart and stopped in front of them.

Zhao Changjiang stopped the doctor who was about to push the door open and asked, "What are you doing here?"

The doctor said calmly, "I'm here to give the patient an injection." He pointed to the medicine bottle on the cart.

Zhao Changjiang said, "There are no patients in this ward who need medication. You've come to the wrong place."

Upon hearing this, the doctor quickly stepped back and carefully looked at the ward number written in red paint above the ward. Then he slapped his forehead and said, "Wrong, wrong, it's number 306. Sorry, sorry."

Zhao Changjiang said nothing, pointing to the next room, "Room 306." Then he felt a little strange. Why were they coming in the middle of the night for injections? Why hadn't they been given injections before? The nurse hadn't told him there would be any injections at night.

"What kind of injection are you getting?" Zhao Changjiang suddenly asked.

The doctor, who was almost at the door of the next ward, stopped and turned to Zhao Changjiang and said, "The patient is weak and needs some special nutrients. I'm giving him a nutritional injection."

Zhao Changjiang didn't understand these things, so he asked out of caution. Seeing that he answered fluently, he naturally relaxed his guard and said, "Oh, then go ahead."

The doctor took a few steps forward and stopped in front of Ward 306. He was also questioned by the soldier guarding the ward door. He answered fluently and was quickly released.

The door of the ward opened, and Xu Jinbu followed the doctor into the ward. He stood aside and watched the doctor take out large and small bottles of medicine, then mixed several medicines together with a syringe, hung them on a stand, and prepared to give an injection to Professor Gu lying on the bed.

Just as the sharp needle was about to pierce Professor Gu's blood vessel, a figure rushed into the ward, rushed to the bed and grabbed the doctor's hand holding the needle.

A flash of panic crossed the doctor's eyes, but he quickly calmed down.

"Comrade, what are you doing?" the doctor asked with a frown.

Song Yun stared at the doctor. It was Zhang Sheng's face. This was not the doctor the director arranged for them when they were admitted to the hospital.

"This is my problem. What are you doing?" Song Yun asked.

The doctor said, "Can't you tell? I'm giving the patient an injection. He's weak and needs nutritional supplements. This is a nutritional injection."

Song Yun knew Professor Gu's treatment plan very well. The doctor didn't prescribe any nutritional injections at all. Besides, it was impossible to give nutritional injections in the middle of the night. It was obvious that something was wrong.

But he didn't expose him immediately. Instead, he took a detour to test him. "Professor Gu didn't prescribe the nutritional injection. It's the old man who needs the nutritional injection. Did you get the wrong person?"

The doctor's eyes lit up. This was a complete turn of events.

"Yes, I want to give Comrade Su Jiansu a nutritional injection. Isn't this Comrade Su Jianfeng?" The doctor immediately made a surprised expression, as if he couldn't believe that he had made a mistake.

Song Yun curled her lips, and with a force on the hand that was holding the doctor's wrist, she directly dislocated the doctor's arm.

A scream rang out in the silent night, startling everyone, whether asleep or not.

The two professors were also awakened. They were shocked by the scene and quickly shrank into the corner.

"You, what are you doing? Why are you doing this to me?" The doctor tried his best to hide his inner panic and pretended to be angry. The pain was real, but what he was more concerned about now was whether he had been exposed.

All the special forces members inside and outside the door picked up their guns and aimed at the doctor in the ward.

Song Yun kicked the doctor to the ground, quickly searched his body, and found a delicate scalpel hidden in his sleeve.

"This is what I carry with me for self-defense. You can't frame me for this." The doctor shouted.
