The old man’s ailment wasn't actually complex; he had suffered a heart attack triggered by poisoning. Fortunately, the medicine he carried was excellent, and his family administered it, otherwise, he likely would have been lost already.

Moreover, the subsequent handling by that man was spot on. Once the old man suffered a sudden heart attack, it was indeed unwise to move him around carelessly. If anyone had attempted to help him up or used something to elevate him before Zhang Yang arrived, other accidents could have occurred, preventing Zhang Yang from rendering aid.

Regardless, the outcome now was positive. Although Zhang Yang couldn't completely expel the poison from the old man, he had at least brought it under control, making the next steps significantly easier.

The ambulance had arrived at the door, and the paramedics quickly disembarked.

"Xiao Yong!"

The man, just about to greet the doctors, suddenly turned back, his face alight with sheer ecstasy.

The old man lying on the ground had opened his eyes. The faint voice that had just called out belonged to him. Although the sound was small, the surroundings were quiet now, and everyone had heard it.

"I'm here, Grandpa. How are you feeling?"

The man hastily squatted down, gently supporting the old man's neck, and spoke with extreme care.

"Help, help me up!"

The old man labored over the few words. The man hesitated again, looking up towards Zhang Yang.

Zhang Yang simply nodded to him. He had stabilized the old man’s condition; standing up now wouldn't cause any major issues, and there was no need to keep such an elderly man lying on the cold ground.

"Alright, slowly now!"

Seeing Zhang Yang nod, the man immediately began to gently assist the old man to rise. Zhang Yang’s earlier actions, coupled with the old man’s revival, had firmly established his identity as a doctor in everyone's eyes.

Not just a doctor, but a remarkably skilled one.

The paramedics approached, frowning slightly as they observed the scene, but they proceeded to examine the old man and move him onto the stretcher.

"He was poisoned by the Tiehaitang flower poison. This poison is usually harmless and not fatal, but it accelerates the heart rate and weakens the pulse. If someone with a pre-existing heart condition is exposed, it becomes extremely dangerous!"

Zhang Yang suddenly said this to the man, who paused momentarily before turning back to look at Zhang Yang in astonishment.

The man was intelligent and grasped the implication of Zhang Yang’s words immediately. This poison posed little threat to ordinary people—those with strong immunity might even recover naturally—but for someone with heart disease, it was equivalent to a top-tier poison like Hedinghong.

If that was the case, the old man’s poisoning seemed rather suspicious. If Zhang Yang could see the underlying issue, the man certainly shouldn't have been unaware of it.

"Sir, I owe you a great debt. Qin Yong will remember this. I wonder if you have time to accompany us to the hospital?"

The man bowed deeply, addressing Zhang Yang with profound respect. At this moment, he harbored no further doubt regarding Zhang Yang’s words; if he hadn't identified the root cause, he wouldn't have been able to revive his grandfather so directly.

"I won't be coming to the hospital. Tell them to be careful when removing the needles. The poison from the Tie Tang Hua can be cleared with common antidotes. Keep a close watch on the old man, and contact me if anything else arises!"

Zhang Yang shook his head slightly but still handed the man his mobile number, just in case any unforeseen complications occurred. Seeing a rescue through to the end was always his style.

Tiehaitang is also known as Crown of Thorns, a spiny ornamental plant originally from Africa, thriving easily in tropical regions.

Tiehaitang is poisonous; practically every part of it contains toxins, with the sap being the most potent. It causes significant skin irritation, and ingestion can lead to nausea, dizziness, vomiting, and in severe cases, death.

The Tiehaitang flower is beautiful, but its scent is foul. This elderly gentleman was poisoned specifically by the flower toxin. Generally, such strongly scented toxins are difficult to contract accidentally. If the old man wasn't careless, the situation becomes far more complex—it was highly likely to be deliberate.

Knowing he had heart disease, someone might deliberately administer this flower poison. If complications arose, it would appear as a sudden cardiac event, leading no one to suspect foul play.

For this very reason, Zhang Yang preferred not to accompany the man to the hospital. He was merely a doctor; his duty was to save lives. Such complex matters should be left to the police or handled by the family themselves.

After all, he had said what needed to be said and done what was necessary.

The ambulance soon departed, and the old man’s companions left with it. Hotel guests and staff gradually dispersed, and the entrance returned to its usual appearance.

"Zhang Yang, impressive!"

Su Zhantao leaned beside Zhang Yang, giving him a decisive thumbs-up, watching him with deep admiration.

Wu Sheng, standing nearby, also wore an expression of intense surprise, staring fixedly at Zhang Yang, lost in thought.

"It wasn't a major illness. If he hadn't been poisoned, this accident wouldn't have happened. Let's go back and rest!"

Zhang Yang smiled and shook his head. After all that commotion, they all felt exhausted and retreated to their rooms.

There was still time before evening, so the two men retreated to their separate rooms for a nap. Wu Sheng, however, returned to the market on his own, as Su Zhantao’s shops still required his attention.

After sleeping for two hours, Zhang Yang felt significantly refreshed upon waking. He hadn't used much internal energy while treating the old man today, and it had fully recovered by now.

It was only a common poisoning; had it not been for the heart condition, the situation wouldn't have escalated.

He knocked on Su Zhantao’s door. The man was still asleep and was only roused groggily by Zhang Yang before going to wash up. Su Zhantao had driven the entire way and was more tired than Zhang Yang, accounting for his longer sleep.

After finishing their ablutions, the two headed downstairs together. Zhang Yang wouldn't have woken him if it wasn't nearing dinnertime. If he continued sleeping at this hour, he might easily sleep until midnight, which would disrupt his circadian rhythm and harm his health.

"Sir, hello!"

As soon as they exited the elevator, a man in a white shirt approached them from a distance. He was quite robust and bowed deferentially to Zhang Yang with a respectful greeting.

"And you are?"

"I am Mr. Qin's bodyguard. Mr. Qin specifically instructed me to wait for you here. Since he couldn't leave the hospital to come himself, he sent me to express his gratitude."

The man spoke respectfully while producing a small box, which he immediately presented to Zhang Yang.

The box was light. Upon opening it, Zhang Yang was astonished to find a superior set of silver needles, with a bank check placed next to them.

After the ambulance arrived that afternoon, Zhang Yang had not removed the few needles he had inserted; the old man had taken them to the hospital.

The silver needles themselves weren't expensive. Zhang Yang had intended to buy a new set himself later—it wasn't a major issue, especially since they were in Jiao Yi where many people sold such items. Furthermore, those were hospital property, and he would have needed to return them anyway.

He hadn't expected the man to be so thoughtful as to prepare them for him already.

"Two hundred thousand, that’s quite generous!"

Su Zhantao glanced at the check and then smiled. The figure on the check was substantial: a full two hundred thousand RMB. In this era, anyone offering two hundred thousand as thanks was truly wealthy.

Much like Su Shaohua, whose first gift to Zhang Yang was valued at over one hundred thousand.

"Please convey my thanks to Mr. Qin. I accept these gifts and wish the elderly gentleman a swift recovery!"

Zhang Yang smiled faintly, closed the small box, and said softly.

The bodyguard nodded, bowed again, and then turned to leave. His mission was simply to deliver the items to Zhang Yang. Now that it was complete, there was no need for him to linger.

Su Zhantao’s eyes flickered slightly, showing a moment of surprise before immediately returning to normal.

He had expected Zhang Yang to feign modesty about the two hundred thousand before finally accepting it, but Zhang Yang hadn't offered any pleasantries at all, accepting it directly with no change in expression.

However, this demeanor was something Su Zhantao appreciated. He disliked people who were overly contrived, who rejected something they clearly desired with empty gestures.

Zhang Yang, of course, was oblivious to Su Zhantao’s thoughts, and if he knew, he would only laugh.

Two hundred thousand, in Zhang Yang’s view, was merely a consultation fee. Many of his house calls for the wealthy in his previous life commanded higher fees; this amount was simply standard in his estimation.

He was a doctor; saving lives was his profession, but he wasn't a philanthropist. He wouldn't refuse a genuine expression of gratitude offered to him. As long as it was something he had earned, he would accept it without reservation.

Moreover, in his past life, Zhang Yang often heard his grandfather recount stories of how 'a great, unreturned favor breeds enmity.' Doctors frequently bestowed significant favors upon people, and refusing recompense could actually make those recipients uncomfortable, potentially leading to an inverse reaction.

Therefore, both in his previous life and now, Zhang Yang never refused the tokens of appreciation offered for his efforts. It was the same when Su Shaohua gifted him that antique small bowl; he accepted it immediately without any pretense.

The two walked outside together. As soon as they stepped out, Wu Sheng hurried to meet them.

Wu Sheng had arrived a while ago and had been waiting by the entrance. He was holding several printed documents on white paper.

These documents were not in a folder; he held them in his hand. As soon as Zhang Yang and Su Zhantao got into the car, Wu Sheng handed all the papers to Su Zhantao.

These files detailed the recent price trends for Sanqi (Panax notoginseng). Before resting in the afternoon, Su Zhantao had instructed him to collect this information. Wu Sheng’s efficiency was commendable; in a short time, he had gathered the complete price list for Sanqi over the last month.

"The price for 20-head Sanqi has shot up this high!"

Su Zhantao exclaimed immediately after taking a look. The sheet he held was the latest price update; the 20-head variety had risen to over fifty yuan per kilogram. He recalled that when he last left, the price for 20-head Sanqi was hovering around thirty yuan. In less than half a month, it had nearly doubled.

Su Zhantao’s heart couldn't help but quicken slightly. He understood that speculators were indeed manipulating the Sanqi market. The key now was calculating precisely when and how to enter, and when to exit. If the calculations were accurate, they were sure to profit handsomely this time.

Thinking of this, he glanced at Zhang Yang again. If Zhang Yang truly possessed inside information, it would save them considerable effort and guarantee substantial gains.
