Mr. Yan, wake up! Your wife isn't a delicate little flower.

This hospital also belongs to Yan Mingchuan's family.

It is a very large comprehensive hospital.

It has an outpatient department, a sanatorium, an inpatient department, and a health check-up center.

This is the largest medical examination center in City A.

Many high-ranking officials and dignitaries come here for medical checkups.

Many large enterprises even have close cooperative relationships with this place, and they organize people to come here for physical examinations every year.

Yan Mingchuan makes a high profit every year just from the hospital's health check-up center.

Su Jin whispered, "Brother Yan, everything's arranged. The whole place has been booked for this half-day, so no one else will see you."

"Um."

The four of them went straight to the blood-drawing area as soon as they entered.

Besides the blood test, there were several other tests that required fasting, so Yan Mingchuan did not eat breakfast.

"Mr. Yan, let's draw blood here."

The nurse knew who was having their blood drawn today, nervously clenched her sleeves, and waved to Yan Mingchuan.

Su Jin pushed him over.

While having his blood drawn, Bai Ce looked around, while Cheng Xihe stared at the nurse who was drawing blood from Yan Mingchuan.

She stood next to the water dispenser, leaning against the door of the ophthalmology department, her gaze following the nurse's every move.

The nurse's hands trembled almost imperceptibly, a fine bead of sweat appeared on her forehead, and her breathing was somewhat rapid.

What's there to be nervous about?

Seeing that she looked guilty, Cheng Xihe went over to her.

She gave Bai Ce a look and then hid on the other side.

The nurse, holding three vials of blood samples, head down, quickly left to send them for testing.

Cheng Xihe followed silently behind.

Instead of going to the testing department, the nurse pushed open the large iron gate at the top of the stairs.

Stopping in his tracks, Cheng Xihe raised an eyebrow and darted after him.

Inside the stairwell, the nurse's tense breathing was very loud.

Cheng Xihe followed lightly behind, like an elegant cat.

The nurse stopped at the top of the stairs on the eighth floor: "Hey, come out."

"They're here."

A man wearing a black hat and with a hoodie covering his head walked over.

He also had a backpack clipped to his waist.

Cheng Xihe silenced his phone, turned off the flash, and turned on the camera to record video.

The nurse's hands trembled with nervousness: "I don't know why, Mr. Yan suddenly said he wanted to get tested. Did you bring the necessary documents?"

"Um."

The man deliberately lowered his voice and took out three prepared bloodstains from his fanny pack: "Same as always, give me these."

"OK."

The nurse's hands were trembling, and she couldn't put them down properly for a long time.

"waste!"

The man cursed under his breath and quickly swapped the two samples.

After changing, he looked at him with disdain: "This isn't the first time you've done something like this. Why are your hands shaking?"

"This was so sudden. I got nervous when I saw Mr. Yan's eyes." The nurse breathed a sigh of relief when she saw that he had changed.

The man rolled his eyes: "You'd better watch out."

"You also need to clean Mr. Yan's blood thoroughly," the nurse instructed.

The man said impatiently, "Alright, alright."

A hint of coldness flashed in Cheng Xihe's eyes.

There really is a ghost around Yan Mingchuan.

Two can be caught during a surprise medical check-up; who knows how many more are around?

She turned off the video, not wanting to alert the two of them immediately, and instead walked downstairs.

The nurse carried the samples back and pushed open the door to go inside.

Cheng Xihe waited a few minutes after she left before going inside.

After she came out of the stairwell, she looked around and noticed that the nurse was heading towards the restroom.

After going inside, Cheng Xihe locked the toilet door.

Hearing the sound of flushing water, she hid next to the nurse's restroom, using the door as cover.

As soon as the nurse stepped out, Cheng Xihe rushed up and delivered a karate chop.

The nurse groaned and fainted.

Cheng Xihe quickly grabbed her and threw her back onto the toilet.

Standing in front of the mirror, she slowly washed her hands. Amidst the gurgling water, her mind raced, and she decided to go to the testing room first.

The testing room was quite empty at the moment; no one had come yet.

Cheng Xihe looked at it after the meeting downstairs.

The blood test center staff don't start work until about 8:30, so there are still about ten minutes left.

Cheng Xihe's eyes darted around.

The testing lab is now piled high with blood samples, all of which are labeled.

Only Yan Mingchuan's three stood out awkwardly on the side.

She randomly picked three vials and put them in, then took away Yan Mingchuan's three vials of blood.

Back in the car, Cheng Xihe put away the blood sample and went to a convenience store to buy some transparent tape.

The man at the stairwell just now, whether out of carelessness or something else, wasn't wearing gloves.

After taking a rubbing of the person's fingerprints, Cheng Xihe called Bai Ce: "You don't need to keep an eye on things anymore. Take Yan Mingchuan's blood sample for testing."

I also left a bag in the car with fingerprints inside. You can also get a check-up done at our web-based system while you're at it.

"OK."

Boze did not act immediately.

After Cheng Xihe returned, they exchanged a glance.

"Stay put here and do your best. If anything happens, call me immediately." Bai Ce nodded to Cheng Xihe and left.

Following behind Yan Mingchuan, Cheng Xihe frowned.

The fact that someone tampered with Yan Mingchuan's blood indicates that the other party desperately needs him.

But blood is drawn more than once or twice, and it's impossible for it to be done in the same place. So why are those people able to prepare the samples in advance every time?

There are ghosts too.

The person who could pull off such a scheme right under the noses of the Yan family and Yan Mingchuan must be someone close to Yan Mingchuan.

It's possible that it's even one of his relatives.

"Where did the Ghost Hand Doctor just go?" Having just come out of the internal medicine department, Yan Mingchuan was sitting on the sofa flipping through a magazine, looking relaxed.

When he saw Cheng Xihe coming over, he just asked casually.

Cheng Xihe did not answer directly: "Why is President Yan here? Aren't you going to continue with the medical examination?"

I'm hungry.

Yan Mingchuan lowered his eyes and flipped through the magazine pages: "I've finished all the fasting tests, so it should be okay to eat breakfast now, right?"

"Um."

Cheng Xihe sat down. "I just took care of something. I'll tell you after your physical exam."

Yan Mingchuan paused slightly, then looked at Cheng Xihe seriously: "Is this my business?"

"certainly."

Cheng Xihe didn't say anything more.

This health checkup center is both private and efficient.

The journey was smooth and unobstructed.

Yan Mingchuan cooperated in completing the inspection, while Cheng Xihe followed behind, checking off items as he went.

Apart from some muscle atrophy in the legs, there are no problems with any of the body's functions.

"See? I'm fine."

Yan Mingchuan shrugged: "The blood test results will be available soon, in about half an hour."

"Doctor Ghost Hand, will this work?" Su Jin glanced timidly at Cheng Xihe, then lowered her head again.

Cheng Xihe sneered, "What's the rush? We don't need to look at the blood yet. Just come with me."

"Hey, Dr. Ghost Hand, where did that person who was with you go? Where's your driver?" Su Jin asked, puzzled.

Turning around, Cheng Xihe said coldly, "You're too noisy."

Following them back to the limited-edition car, Cheng Xihe said, "Open the door."

"Hey, Dr. Ghost Hand, isn't your driver giving you a ride?" Su Jin asked, opening the car door nonetheless.

Cheng Xihe: "I'll walk with you for a while."

As soon as he got into the car, Cheng Xihe took out his phone and used a device to check the car. There were no eavesdropping devices or surveillance footage in the car.

Su Jin, who was sitting in front, couldn't sit still any longer: "Dr. Ghost Hand, what are you doing?"

Cheng Xihe scanned the area again, but still found nothing: "It's none of your business, stop asking."

"Let's check the eavesdropping equipment?" Yan Mingchuan said calmly.

Cheng Xihe glanced at him and said, "Hmm."

"What kind of listening device could there be? I've had the car keys the whole time. Anyway, I didn't find anything out during today's medical checkup..."

Su Jin made a couple of sarcastic remarks, thinking that the "ghost hand" was nothing special, just like doctors in hospitals who trick people into having tests done.

Cheng Xihe glanced coldly at Su Jin: "Who said I didn't gain anything?"
