Kangxi also had some knowledge of medicine. He only needed to observe the pale and grayish complexion of the person in front of him to know that this person would not live long.

"How long has he been taking opium?"

"More than a year."

"It's become like this in just over a year?"

Kangxi suddenly looked up, his face showing unconcealable surprise.

"He was a small manager in the tavern. He used to have a good life, but after he became addicted, he spent almost all his earnings on opium paste. He only ate enough to fill his stomach that year. It's bad for a normal person not to eat well, let alone someone who's been poisoned."

After Yinzhen finished speaking, he saw the waiter crying uncontrollably. He curled his lips and added,

"This guy used to have parents, a wife, and children, but ever since his drug addiction got worse, he never brought any money home, even..."

Yinzhen gritted his teeth and couldn't bear to say anything more.

"Even what?"

Kangxi was puzzled.

Yin'er's face was full of pity. He felt that he was already cold-hearted enough, and after hearing what the waiter said, he couldn't help but want to draw his sword.

"He even...in order to stop his parents, wife, and children from objecting to his opium smoking, he even gave them opium paste in the middle of the night."

"What?!"

Kangxi was shocked again.

Yinzhen commented with a complicated heart,

"He's no longer a human being, he's a beast!"

If this man was not still useful, he would really like to kill him with a knife to prevent him from wasting food in this world.

Kangxi's face fell. After thinking for a moment, he summoned the imperial physician he brought with him.

Lin Wei Kai looked at the tightly wrapped human figure on the ground and felt his scalp tingling.

Who in their right mind would wrap themselves like this?

Lin Wei Kai knelt on the ground to feel the pulse of the waiter. But after a few breaths, the expression on his face turned solemn.

After carefully examining it for a moment, Lin Wei Kai cautiously switched to the other wrist and continued taking the pulse.

Then he opened the waiter's mouth and observed the condition of his gums.

Kangxi and Yin'er looked at Lin Weikai's face and frowned fiercely, until Lin Weikai finished observing his gums and blurted out -

"Longevity cream!"

Kangxi's hands trembled slightly behind his back, and he hurriedly asked,

"Do you know that the poison he was poisoned with was the longevity ointment?"

In fact, Lin Wei Kai began to regret it after he said those three words.

His ancestor was also an imperial physician, and the hand-carved notes left behind recorded this bone-melting poison.

It has only been a few years since the Manchus entered the Pass. He is of Han Chinese descent, so it is naturally impossible that his ancestors served the Qing imperial family.

Lin Wei Kai's mind was full of thoughts, and the expression on his face became increasingly ugly.

Before his father died, he said he was brainless. He was a little unconvinced at the time, but now looking back, he really was... brainless!

Even if you know it is the longevity cream, you can't say it so openly!

"Yes, I know he was poisoned by the longevity cream."

The arrow is on the string and has to be shot. There is no point in him regretting it. It is better for him to tell the truth.

Otherwise, he would not be able to bear the consequences of fooling the emperor.

"How did you learn that?"

"My family has been practicing medicine for generations. When I was young, I saw the pulse record of a person who had been poisoned by this poison in my grandfather's handwritten notes."

Kangxi was stunned for a moment, then he thought carefully about Lin Weikai's background, and quickly widened his eyes and said,

"Your grandfather..."

He suddenly stopped talking midway through his sentence.

After the Qing army occupied the capital, they killed all the civil and military officials who could be killed, but many people with special skills were left behind.

Lin Weikai's grandfather was still alive at that time. For the sake of his wife, children and the elderly at home, he was forced to save many injured Manchus, so his identity as an imperial physician was retained.

In other words... Lin Wei Kai's grandfather was in the palace of the previous dynasty and it is very likely that he served the royal family.

The handwritten notes he left behind recorded the pulse records of the royal family of the previous dynasty.

Kangxi felt his heart sink.

In the entire hall, only Lin Weikai understood what Kangxi had not said. He smiled bitterly and replied in a sullen tone.

"yes."

Seeing the emperor and his ministers playing dumb, Yinzhen asked with a hint of dissatisfaction,

"Father Emperor, is there anything wrong with what he said?"

Kangxi's eyes were a little dazed.

It turns out that the royal family of the previous dynasty was also contaminated by the longevity cream!

Thinking of what he heard from Yinreng's inner voice, that the Eight Banner Army was full of drug addicts, Kangxi's low pressure all overflowed.

Yinzhen looked at Kangxi's changeable expression and felt even more confused.

But Kangxi ignored him, and he didn't dare to ask again.

Otherwise, Kangxi would most likely take his anger out on him.

Kangxi was silent for a long time before he asked Lin Weikai,

"Can this person be saved?"

Lin Weikai shook his head.

"His body is seriously weakened. Even if he is kept alive by precious medicine, his life span will definitely not exceed one year."

Upon hearing this, Yinzhen thought to himself that this guy's diagnosis was exactly the same as that of the doctor.
