I am the Holy Poisoner, the Empress advised me to calm down

As soon as Liu Ying finished speaking, Liu Hong suddenly convulsed all over, black blood gushed out of his mouth, his eyes rolled back, and he collapsed on the bed.

"Grandpa!" Liu Ming and Liu Ying rushed over at the same time, their voices trembling.

Wang Dingguo hurriedly stepped forward to feel the patient's pulse, cold sweat breaking out on his forehead: "Not good, the condition has deteriorated rapidly, the heart pulse is disordered, this..."

"Didn't you say you were sure?" Liu Ming asked with red eyes.

"I... I didn't expect this to happen." Wang Dingguo was at a loss. After giving Liu Hong several injections, his condition did not improve, but his breathing became weaker.

The room was in a state of panic, and the servants were too frightened to speak. Liu Ying cried bitterly, holding her grandfather's hand and calling out to him.

Just when everyone was at a loss, Liu Ming suddenly remembered something and turned around to look at Zhang Jun who had been watching coldly.

"Zhang Jun, please, save my grandpa!" Liu Ming knelt down directly.

Zhang Jun stood in the corner, his expression indifferent: "Didn't you just say that my medical skills are not good?"

"It's all my fault. I apologize!" Liu Ming kowtowed. "As long as you can save my grandfather, I'll agree to any condition!"

Liu Ying also knelt down, tears blurring her eyes. "Zhang Jun, I was wrong. I shouldn't have said that to you. Please, for the sake of us growing up together, please save Grandpa!"

Although Wang Dingguo was unwilling to give up, he had no choice but to humble himself when he saw Liu Hong dying. "My dear brother, I am not a good doctor, so please help me."

Zhou Xuewei watched anxiously from the side, wanting to speak but not daring to.

Zhang Jun looked at Liu Hong lying on the bed, then at Liu Ming and his sister kneeling on the ground, and sneered, "Now you know how to beg me?"

"Zhang Jun, what do you want in exchange for taking action?" Liu Ming gritted his teeth.

"I can save him." Zhang Jun slowly walked towards the bed, "But I have a condition."

"What conditions?"

"From now on, no one is allowed to question my medical skills." Zhang Jun glanced at everyone present, "Including you."

"Okay, I agree!" Liu Ming nodded without hesitation.

Zhang Jun took out a medicine bottle from his bosom and poured out a black pill. The pill exuded a faint medicinal fragrance and looked ordinary.

"What is this?" Wang Dingguo couldn't help but ask.

"Life-saving medicine." Zhang Jun stuffed the pill into Liu Hong's mouth and took out the silver needle bag. "Everyone, get out of the way."

Everyone stepped back quickly, only to see Zhang Jun's silver needles flying like flying, quickly inserting seven needles into Liu Hong's body, with each needle positioned extremely precisely.

Wang Dingguo widened his eyes. This acupuncture method... This is the Seven Star Life-Sustaining Needle!

The legendary Seven Star Life-Sustaining Needle, lost centuries ago, was unexpectedly used by this young man. The acupuncture technique was simple yet profound, and each stitch seemed to carry ancient wisdom.

As the last needle was injected, Liu Hong's breathing gradually stabilized and his face regained color.

"Grandpa..." Liu Ying called cautiously.

Liu Hong slowly opened his eyes. Although he was still weak, he was conscious.

"That's great!" Liu Ming was so excited that tears filled his eyes.

Wang Dingguo was so shocked that he was speechless. He had been practicing medicine for decades and had never seen such a miraculous acupuncture technique. This was definitely a truly unique medical skill!

"You...you are using the Seven-Star Life-Renewing Needle?" Wang Dingguo's voice trembled.

Zhang Jun put away the silver needle and did not answer.

"It really is the Seven-Star Life-Sustaining Needle!" Wang Dingguo suddenly knelt down, "Please accept me as your disciple!"

Everyone was stunned. The famous doctor Wang Dingguo actually wanted to take this young man who looked only in his twenties as his teacher?

"Doctor Wang, what are you doing..." Liu Ming couldn't believe it.

"You don't understand," Wang Dingguo said excitedly, "The Seven-Star Life-Sustaining Needle is a long-lost, peerless acupuncture technique. Anyone who can master this technique is definitely more skilled than me!"

Zhang Jun looked at Wang Dingguo, who was kneeling on the ground, indifferently: "Get up, I don't accept disciples."

"Master, please accept me!" Wang Dingguo showed no intention of getting up. "I'm willing to give everything I have in exchange for your guidance!"

"Doctor Wang, why do you have to do this?" Zhou Xuewei couldn't help but ask, "Your medical skills are already very high, why do you have to..."

"You have no right to interfere." Zhang Jun glanced at Zhou Xuewei coldly.

Zhou Xuewei's face changed and she had to step aside.

Wang Dingguo continued to kneel: "Master, I know you look down on me, but I really want to learn your medical skills. I can start from the most basic, even if it's just to help you!"

Seeing this usually arrogant doctor humble himself, Zhang Jun was also touched. After all, someone who could lower himself to study at least showed that he was sincere about medicine.

"Okay, I'll accept you as my registered disciple," Zhang Jun finally said. "But whether I can officially become your disciple depends on your performance."

"Thank you, Master!" Wang Dingguo was so excited that he almost cried.

Liu Ming and Liu Ying exchanged a look of shock. When had Zhang Jun, who had grown up with them, become so powerful?

"Zhang Jun, thank you for saving my grandfather." Liu Ying said sincerely, "I was wrong before. I apologize."

"Forget about the apology," Zhang Jun looked at the sky, "I should go now."

"Wait!" Liu Ming hurriedly stopped him, "My grandfather's illness hasn't fully recovered yet, you can't leave!"

"Yes, Zhang Jun, please stay and take care of grandpa." Liu Ying also pleaded, "Our Liu family will definitely treat you well."

Zhang Jun thought about it and realized that he really had nowhere else to go, and Liu Hong's condition still needed follow-up treatment.

"Okay, I'll stay for now."

The Liu family's attitude towards Zhang Jun changed 180 degrees.

The housekeeper personally arranged the best guest room, right next to Liu Ying's bedroom. The room was antique and beautifully furnished, more luxurious than any other place Zhang Jun had stayed before.

"Zhang Jun, how about this room?" Liu Ying pushed open the door and asked nervously.

"Not bad." Zhang Jun glanced at it casually.

"Well...if you need anything, you can always come to me." Liu Ying said shyly, "I'm just next door."

Zhang Jun nodded without saying anything more.

During dinner, Liu Ming specially opened a bottle of good wine to calm Zhang Jun down.

"Zhang Jun, today is really thanks to you." Liu Ming raised his glass, "This glass of wine, I toast to you!"

"You're welcome." Zhang Jun responded indifferently.

Wang Dingguo was also there to accompany him. He was extremely respectful to Zhang Jun and asked him some medical questions from time to time.

After dinner, Zhang Jun returned to his room and was about to rest when he heard a slight noise coming from next door.

At first he didn't pay much attention, thinking it was Liu Ying moving around in the room. But after a while, the noise suddenly stopped, and then there were light footsteps outside the door.

Zhang Jun frowned. Who is walking in the corridor so late?

The footsteps got closer and closer, and finally stopped in front of his door.

Zhang Jun held his breath and listened carefully.

With a "click", the door was gently pushed open.

A white figure slowly walked in. It was Liu Ying in pajamas.

But what was strange was that Liu Ying's eyes were closed, her face had no expression, and her movements were a little stiff.
