Reborn as a doctor, he takes revenge and ruthlessly punishes the scum.

Physician Liu, who had been feeling quite smug, was suddenly struck by her question, which pierced his deepest, most hidden feelings. In his panic, he forgot his pretense, abruptly looked up to meet Yu Shuyan's eyes, and blurted out:

How did you know?

However, before he could finish speaking, he suddenly realized his mistake, abruptly interrupted himself, and changed his words:

"What are you talking about? I... I don't understand."

Gong Qiuyan, however, sensed something was amiss and looked at Yu Shuyan with suspicion:

"What...what do you mean?"

Yu Shuyan smiled slightly at Gong Qiuyan:

"Your Highness is unaware that the young prince has been bedridden for years not because he is ill, but because he has been poisoned!"

"Poisoned?!"

Gong Qiuyan exclaimed in surprise.

Physician Liu's eyes widened suddenly, fear flashing in them:

How could that be? How could she possibly know?

That thing, so many famous doctors have never discovered it over the years, how could she possibly have discovered it?

His undisguised expression made Gong Qiuyan, who was looking at him, instantly understand what was going on.

Gong Qiuyan pointed at Imperial Physician Liu, her voice terrifyingly low:

"Tell me, was it you? Was it you who poisoned me?!"

At this moment, Imperial Physician Liu calmed down. He knew that he could not admit to this under any circumstances. Otherwise, not only would Gong Qiuyan want to kill him.

His betrayal will cost him his life.

Having figured this out, Imperial Physician Liu immediately adopted a puzzled expression:

"Your Highness, I truly do not know, I know nothing! My medical skills are inadequate; all these years I have only known how to take meticulous care of the young prince. As for the prescriptions for his treatment, those were all written by the Imperial Medical Academy. I really know nothing!"

As he spoke, he looked anxiously at Physician Ding and pleaded:

"Ding, please put in a good word for me. Over the years, all the medicines have been prescribed by the Imperial Hospital, and the people from the Princess's residence have been in charge of dispensing and decocting them. Even if I wanted to poison someone, I couldn't."

Doctor Ding frowned slightly as he looked at Yu Shuyan:

“Yuan Niangzi, what he said is true. He has no contact with the prescription, dispensing, decoction, or feeding of medicine. Over the years, he has only been responsible for taking care of the young prince. As for him poisoning him, it is really not very likely that he would have the opportunity.”

Imperial Physician Liu immediately perked up and echoed:

"Yes, yes, it really has nothing to do with me."

He didn't believe in the saying "catch the thief with the stolen goods," and he stubbornly refused to admit it. They certainly couldn't possibly have that kind of evidence.

He was, after all, an official appointed by the imperial court, so they really couldn't do anything about him.

Thinking of this, and filled with hatred for Yu Shuyan, he unconsciously looked at her with a slightly provocative air:

"Madam Yu, you accuse me of poisoning, but do you have any evidence? Also, you say the young prince was poisoned, but do you have any evidence for that?"

If she has no evidence, then she is just making baseless accusations and spreading rumors. Hmph, it's really hard to say who will be held accountable.

Yu Shuyan could easily see the provocation in his eyes, and the corners of her mouth unconsciously widened even further.

"Since you want the evidence so badly, then I'll give it to you."

As she spoke, amidst the curious gazes of the crowd, she opened her hands and extended them towards them:

"This is the evidence!"

The moment everyone saw what was in her hand, they were instantly disgusted, and then they were all shocked.

Especially Physician Liu, he was the most shocked and terrified. Unconsciously, he slumped to one side, his face as pale as paper.

Yu Shuyan ignored him and instead looked at Gong Qiuyan:

"Your Highness, this is a Heart-Devouring Gu. I just took it from the young prince."

Gong Qiuyan's eyes were filled with regret. She couldn't imagine how much pain this thing had brought Zhou Yunchen over the years.

Yu Shuyan continued:

"When the Heart-Devouring Gu is placed on a person, it will continuously devour the host's lifeblood. The host will become weak and sickly for many years, as if suffering from a congenital deficiency. This is the viciousness of this Gu. It will cause the host to suffer pain without realizing it, until the host is exhausted and dies. And this process is very long, ranging from five or six years to more than ten years, before the host dies from exhaustion of lifeblood."

After Yu Shuyan finished speaking, Gong Qiuyan was already swaying precariously:

"Why, why, why must you treat my son so cruelly!"

Yu Shuyan sighed softly:

"Your Highness, the young prince is your Achilles' heel!"

Upon hearing her words, Gong Qiuyan instantly understood the key point.

After all, she was a royal princess who grew up in the royal family, so she was naturally very clear about these dirty tricks.

She said that all these years, Gong Nanxian and Gong Beige have been so wary of her and suspicious of her, yet why have they never done anything to her?

She had always thought that they were afraid of the senior officials in the court and the opinions of the people, but now she knew that they had already made their move against her.

After all, as long as Zhou Yunchen remained bedridden, she, his mother who loved him dearly, would be too busy running around for him to have time to think about anything else.

Once Zhou Yunchen passes away, she will definitely collapse.

They could then kill her with a legitimate reason, and claim that she committed suicide out of grief for her son. That would be perfectly justifiable.

When that time comes, the Sixteen Guards of Yanyun will have no master and will naturally return to the royal family.

Poisonous! Absolutely poisonous!

Such ruthless methods were indeed something Gong Nanxian and Gong Beige could come up with.

A dense, overwhelming hatred and anger welled up within her. Gong Qiuyan coldly glanced at the Imperial Physician Liu, who was slumped on the ground:

"Do you have anything else to say?"

Physician Liu made one last attempt, sitting up and saying urgently:

"Your Highness, I really don't know anything! I'm innocent!"

Yu Shuyan shook her head slightly:

"Imperial Physician Liu, shall we have someone remove your robes so we can examine the wound on your chest?"

"After all, this Heart-Devouring Gu requires the person who casts the Gu to feed it with their own heart blood every three days!"

A cold glint appeared in Gong Qiuyan's eyes:

"You, rip his clothes off!"

The guards rushed forward and ripped open the imperial physician Liu's clothes, revealing a mixture of old and new wounds on his chest.

Unable to endure any longer, Imperial Physician Liu kowtowed repeatedly to Gong Qiuyan, this time pleading out of sheer terror:

"Please spare me, please spare me! I had no choice, I was forced into this situation, yes~"

However, before he could reveal who was behind him, he was struck between the eyebrows by a hidden weapon, his eyes wide with resentment, and he stopped breathing.

The guards immediately surrounded Gong Qiuyan, cautiously looking around and searching.

Yu Shuyan glanced at Gong Qiuyan, whose face was ashen, and smiled faintly:

"Your Highness, shall we talk?"
