Chapter 69
Song Zhou fell to the ground in the forest, covering his left arm with his right hand, blood oozing out from between his fingers.
Chang Ting helped him sit up: "What happened?"
Song Zhou seemed to be in great pain, his face was pale and his whole body was shaking.
He pointed his chin towards the depths of the woods and spoke with a trembling voice: "That man is heading that way..."
Chang Ting frowned and said to Zhang You, "Take him to get it wrapped up."
I got up and chased in that direction.
He ran a short distance before the hospital wall appeared before him, with a large wooden box resting against its base. He stepped onto the box and peered over the wall...it was the intricate, complex Chunzhi neighborhood again.
There was no male nurse either.
Chang Ting climbed over the wall and found something to step on outside. It seemed like a shortcut that was unobstructed.
There were many alleys outside the wall, and it was impossible to tell which direction the male caregiver escaped. Chang Ting chased him aimlessly for a while, but returned empty-handed. He then returned to the "shortcut" of the wall and returned the same way.
Zhang You has taken Song Zhou to get bandaged.
Chang Ting walked towards the inpatient building and saw Zhou Zhengzheng in a hospital gown, running barefoot. She had already searched everywhere but found nothing.
Seeing Chang Ting, he hurried up and said, "Master..."
Chang Ting looked gloomy.
Zhou Zhengzheng understood, tore off the tube from his body and threw it to the ground, stomping his bare feet in anger: "This bastard!"
Passersby around looked at him sideways, surprised at the patient's strong energy.
Chang Ting frowned: "What are you doing? Calm down and pay attention to the impact!"
"I can't calm down!" Zhou Zhengzheng was shaking with anger. "There was an explosion on the eighth floor, injuring a nurse. I'm sure it wasn't an accident. This beast must have deliberately set the explosion to create chaos!"
Chang Ting felt the blood rushing to his head and he could no longer remain calm.
The nurse's blood hadn't yet dried on the floor of the orthopedic surgery ward corridor. Chang Ting frowned as he looked at the radiating glass fragments.
Zhou Zhengzheng followed up: "Master, what kind of explosive is this..."
Chang Ting turned around and scolded her, "Go back and put on your shoes. Aren't you afraid of getting your feet pricked by all the glass on the floor?"
Zhou Zhengzheng had no choice but to go back to the ward to put on his shoes. When he came back, Chang Ting was squatting on the ground, holding a round piece of glass in his hand.
He held the glass up to the window light and studied the radiating cracks on it.
Zhou Zhengzheng stepped forward and asked, "Master, what is this?"
"The bottom of a glass bottle." Chang Ting said, "The explosive is a glass bottle."
"How could a glass bottle explode?"
Chang Ting brought the bottom of the bottle to his nose and sniffed. "There's a pungent smell of disinfectant left on the glass. It must be a chlorine-containing effervescent disinfectant tablet dropped into a glass bottle filled with warm water, causing the explosion."
He pointed to the chair by the wall and said, "Judging from the radiation from the broken glass, that chair is the explosion point."
Zhou Zhengzheng said angrily, "Disinfectant effervescent tablets... Such a simple trick actually fooled us!"
Chang Ting shook his head in disagreement. "The simpler, the better. These days, the raw materials for explosives are strictly controlled, and public places are heavily inspected. It's definitely not easy to stage an explosion.
"But items like effervescent tablets and glass bottles are easily available to anyone. The suspect, who figured out this trick, is definitely not an ordinary person. Let's call the trace investigators over."
Zhou Zhengzheng went to make a phone call.
Chang Ting simulated the scene in his mind - the "male nurse" put a certain number of chlorine-containing effervescent disinfectant tablets into a thin-walled glass bottle filled with half a bottle of warm water, tightened the bottle cap, and placed the bottle on the chair by the wall.
When the effervescent tablets come into contact with warm water at around 40 degrees Celsius, a chemical reaction occurs, rapidly producing gas. It takes less than a minute for the gas to expand enough to burst the glass bottle.
One minute was just enough time for the "male nurse" to walk leisurely from one end of the corridor to the other end near "Yu Aiai"'s ward.
After the glass bottle exploded, Zhang You, who was guarding the ward as a policeman, could not help but come to check. The "male nurse" took the opportunity to enter the ward... and everything happened just like that.
It’s not a very sophisticated method, but it is effective.
While reviewing the situation, Chang Ting repeated the path the "male nurse" had taken, walked into the ward, came to the bedside, squatted down, and looked at the shoe prints on the ground.
I compared it with my hand and knew it was size 44.
His face was clouded.
The door behind him opened and Zhang You walked in with a crying face.
"I'm sorry, Team Leader. It's all my fault for being too impulsive and falling for the criminal's trick!"
Zhou Zhengzheng, wearing a hospital gown, stepped forward from behind and said, "It's my fault! If I had sprayed him with pepper spray a second earlier, I would have blinded him and he wouldn't have been able to escape!"
Chang Ting stood up, feeling very annoyed. "Alright, alright, one by one... I don't blame you, blame me. I didn't expect this thing to start so early in the morning. Damn, it got up earlier than the chickens, and now it's too arrogant to commit crimes..."
Chang Ting cursed, "By the way, Song Zhou..."
Zhang You said, "Dr. Song was stabbed by that male nurse with a dagger. The injury was serious!"
Chang Ting was shocked: "I remember it was just a small cut on his arm, how could it be serious?"
"It was serious. I needed five stitches!"
"..." Chang Ting took a breath, "Five injections is considered serious? It's not fifty injections!"
Zhang You's eyes widened. "How can doctors be compared to rough guys like us? Five injections is already considered serious!"
"How can a grown man be so delicate? Where are the others?"
"I just finished bandaging and went to change clothes."
Chang Ting sat down on the accompanying chair, crossed his legs, closed his eyes, and tapped his forehead, which was sore from the night, with his index finger. He asked, "Did Song Zhou tell you what happened?"
"He did," Zhang You reported. "He said that when he came to work this morning, before he even entered the building, he saw a caregiver running around in the lobby, pushing down an elderly man on crutches and running out.
"Doctor Song felt that the old man must have been injured a second time. He couldn't let the caregiver get away like that. He had to let him come back to take charge, so he chased after him."
Doubt flashed across Chang Ting's eyes: "What a coincidence?"
Zhang You nodded, "Yes." He said he saw the caregiver running into the grove and followed him in. Unexpectedly, the caregiver suddenly turned around, pulled out a knife and stabbed him.
"He dodged for a moment, but luckily the stab didn't hit him in the vitals, only scratching his arm. He didn't dare to chase after him and could only watch the caregiver run away."
Chang Ting tapped his fingers on the armrest. "This guy is usually so elegant, but he actually dared to chase after a criminal?"
Zhang You clenched his fists, deeply moved. "That's right! I never knew Doctor Song was so brave!"
Chang Ting did not agree.
How come Song Zhou happened to run into a criminal who attempted murder?
Even if it was a coincidence, the hospital has security guards. Shouldn't the normal reaction be to shout and give the security guards directions?
Why does the gentle and refined Dr. Song want to catch up alone?
Ever since the 50% cashmere fiber incident, he has put aside his suspicions of Song Zhou.
But Song Zhou always inexplicably returns to his circle of attention.
Today's coincidence was unusual, forcing Chang Ting to reconsider carefully.
"Suppose..." Chang Ting leaned back, closed his sore eyes, and pinched his brows, "I'm just making an assumption - what if Song Zhou lied?
Zhang You was stunned: "No way?"
"Then tell me, did anyone see him actually running after the caregiver?"
"This...we have to visit to find out." Zhang You hesitated.
Chang Ting closed his eyes and gestured with his fingers in the air: "If no one saw it, would there be a possibility that the caregiver who ran into the grove was actually Song Zhou himself?"
Zhang You and Zhou Zhengzheng both gasped, obviously very shocked.
Chang Ting didn't open his eyes, but shook his finger calmly: "Don't be surprised, listen to my analysis -
"The nursing uniform is very bulky, Song Zhou can wear it over his clothes, take it off after entering the woods, and hide it somewhere.
"Oh, and we have size 44 shoes... That's not a problem. Just prepare a pair and leave them in the woods so we can have a replacement.
"Song Zhou wears size 43 shoes, but he deliberately wore a size larger when committing the crime to confuse people. He could have worn them more securely if he had tied his shoelaces tighter or put in a pair of insoles.
"Then, to make the scene more realistic, he cut himself—as a doctor, he couldn't carry a scalpel with him.
"Then he lay on the ground and pretended to be stabbed. When Zhang You and I went over, he said the male caregiver had escaped by climbing over the wall.
"This way, not only can you get rid of suspicion, but you can also create the illusion that you are brave and righteous, and gain our trust."
Zhang You and Zhou Zhengzheng were both silent, probably shocked by his amazing reasoning ability.
Chang Ting was quite proud: "Don't you think it makes sense? Now, before Song Zhou goes back to destroy the evidence, we just need to go to the grove and see if we can find the nursing uniform..."
As he spoke, he opened his eyes and stood up.
Then he slumped back into his chair.
He looked at Song Zhou who was standing in front of him.
Song Zhou had already changed out of his blood-stained jacket and put on a white coat over his short-sleeved T-shirt. He put his hands in his pockets and looked down at Chang Ting coldly.
Not far away, Zhang You and Zhou Zhengzheng looked up at the sky and the ground respectively, pretending not to be there.
Chang Ting glared at the two traitors and swallowed hard: "When did you come in?"
"From 'It's actually Song Zhou himself.'"
"Why are you walking so quietly?"
"I usually wear shoes with softer soles when I'm doing ward rounds to avoid disturbing the patients." Song Zhou shook his head. "Let's go."
"Where...where?"
"Go to the grove and search the caretaker's clothes." Song Zhou said expressionlessly, his glasses glistening.
