Ye Zhen originally did not intend to get involved in the cause and effect of Doctor Su, but now he knows that this is a conspiracy by Prime Minister Li.

She then had Doctor Su replicate the Li family's medicine, and then sneaked into the Li family's house in the middle of the night to steal the medicine, leaving the replicated fake medicine behind.

"Take a look and see if this is what your grandfather needs?"

Ye Zhen handed the medicine box to Doctor Su.

After the examination, Dr. Su hugged Ye Zhen with a mixture of surprise and emotion, saying, "Thank you, Ye Zhen."

She was already very grateful that Ye Zhen secretly brought her to see her grandfather, but she never expected that Ye Zhen would also help her steal medicine.

She puffed out her cheeks and made up her mind, "I'll do anything you need my medical skills for."

Such a good person as Ye Zhen would have to deal with someone who isn't a good person, like Ye Wantang. In that case, she wouldn't be considered to have broken her vow.

If she really has to go against it, then there's nothing she can do. She's doing this to repay her grandfather for saving her life, and he will forgive her.

Ye Zhen smiled, "Quickly give it to your grandfather."

If it were just a normal marriage alliance, the female doctor Su might be able to use Li Shuhuai and Qin Xue's affair to obtain medicine from the Li family.

But this is Li Heng's scheme to seize the country. Even if Doctor Su catches him in the act, the Li family will not be threatened by her.

Because Li Heng needed to use the life of Imperial Physician Su to force Physician Su to marry into the Li family.

Only if Doctor Su marries into the Li family will the Li family have the opportunity to send their daughter into the palace.

The fact that a usurper wanted to send someone to the emperor and empress's side inevitably reminded Ye Zhen of Xie Jinyao's record: "After the emperor's death, the empress supported a member of the imperial clan to become emperor!"

Ye Zhen was worried that Li Heng wanted to harm the Emperor and Empress, so he hoped that the old imperial physician Su would recover soon and help the female physician Su to cancel the marriage.

If Imperial Physician Su is unwilling to withdraw, then we will make other plans.

Seeing that Female Physician Su had begun feeding the old Imperial Physician Su medicine, Ye Zhen disappeared into the shadows.

Meanwhile, in a dark room in the capital city.

Li Heng looked at Li Shiling in front of him and said, "The Su and Li families will be getting married in a few days. Keep an eye on the Su family and make sure nothing goes wrong."

"Don't worry, the second branch of the Su family is greedy. They would risk their own father's life for a little benefit and prevent the Su family girl from seeing the old imperial physician Su."

An orphan girl without her grandfather's protection can't cause any trouble in the Su family. As long as she doesn't get treatment from the imperial physician, and the old man doesn't wake up, the marriage won't change.

Li Heng nodded slowly, then asked, "Why did the Su family girl suddenly want to break off the engagement? Have you found out?"

Perhaps they've discovered the Li family's scheme.

Knowing his concerns, Li Shiling quickly said, "Don't worry, only the head of the family and I know about the Li family's plans. They won't reach the ears of the Su family's daughter."

She broke off the engagement because Qin Xue couldn't stand it anymore and caused trouble for her, making her aware of Shu Huai and Qin Xue's affair, and she got jealous.

He genuinely couldn't find anything else unusual.

Little did they know that the head of the Li family wanted his daughter to replace Physician Su in entering the palace, so he discussed with his wife and had their unfavored, almost invisible illegitimate daughter overhear and tell Physician Su everything.

Seeing his certainty, Li Heng didn't press further, but warned, "Tell your niece to behave herself. If she doesn't like the Su family girl, once she marries into the Li family, we can do whatever we want with her."

In recent years, he has gone to great lengths to have the eldest daughter of the imperial physician Li family study medicine, so that one day she could replace Physician Su and stand before the Empress.

The emperor and empress were deeply in love, and the emperor was only unguarded when it came to things given to him by the empress.

Li Shiling also knew the importance of this matter. If this crucial moment was messed up, not only would his niece Qin Xue be punished, but he himself would also be punished.

He nodded hurriedly in agreement.

The two chatted for a while longer. Li Heng leaned back in his chair, and Li Shiling hurriedly said, "A few new girls have arrived at the academy. Shall we call them over for you to take a look?"

This is the usual procedure after we've finished discussing the important matters.

This time, Li Heng shook his head. "No need."

Since he agreed to let Xie Jinyao have his child, he no longer needed to waste his energy on other women.

Moreover, Xie Jinyao is a very open person, and she has been clinging to him closely these days, so his desires were exhausted before they could even arise.

He seemed a little tired, and he reached out his hand, "Make some more nourishing pills."

Li Shiling understood what he meant and quickly took his pulse.

He was somewhat surprised after taking the pulse, but he didn't dare to say much. He quickly turned around to prepare the medicine, while wondering in his heart if there was a woman hiding in the Prime Minister's mansion.

The Prime Minister has always taken care of his health and also needs to relieve himself regularly, but these days, the Prime Minister has not come to the secret room.

There are only two old wives at home, and I suppose the Prime Minister wouldn't want to touch them. The one who could completely drain his energy must be a young woman.

Could it be that the Prime Minister has decided to have another child?

Thinking of this, Li Shiling could not hide her excitement.

The fact that the prime minister wants an heir indicates that their grand undertaking is about to begin.

Hearing his increasingly brisk footsteps, Li Heng knew what he was thinking and slightly curled his lips.

It's been planned for many years; that's certainly been a long time.

Li Heng tapped his fingers on the table, and a man in black entered. He instructed, "Once Ye Yunheng successfully assassinates the chieftain of Muya, point the evidence at the emperor. The border town has been quiet for too long; it's time for Xiyue and Dayuan to start a fight."

"yes."

After receiving the order, the man in black reported, "Master, Helian Qing's servants have found the border of the capital. Should we continue to lure them away to another place?"

Li Heng thought for a moment, "No need, just let them come over."

After Helian Qing arrived in the capital, he either followed Xie Tingzhou or Ye Zhen, preventing his people from getting close to him.

Now that the people from the Prince of Dingyuan's mansion have arrived, Xie Tingzhou can't possibly bring them into the palace every day.

After a few moments of silence, he instructed, "Once that boy is free, reveal some information about Shuyu to him."

The grandson of the Prime Minister's family has traveled a thousand miles to find his true relatives; surely he should be allowed to find his true family.

Thinking of this, a fierce look appeared between Li Heng's brows.

Regardless of Xie Jinyao's divination skills, she was right about one thing.

Ye Zhen is a menace if he lives.

According to his original plan, Helian Qing and his servants would be separated and sold to a brothel, and then he would rescue him.

When young children suffer physical or psychological trauma, they become especially dependent on the person who saves them. If they later learn that the person who saved them was their maternal grandfather, they will only become closer to him.

Unexpectedly, Ye Zhen interfered.

Thinking of this, when Li Shiling came over again, he instructed, "The Su family girl once treated Ye Zhen and also attended a banquet at the Marquis of Zhongyong's residence."

This time, the Su family sent an invitation to Ye Zhen, inviting her to attend the wedding of a Su family daughter.

Upon receiving the invitation, Ye Zhen will undoubtedly add to the dowry for the Su family's daughter, and perhaps he can take action against Ye Zhen at the Su family's residence.

Li Shiling also hated Ye Zhen to death.

In the years he lay low, he pretended to be manipulated by Ye Wantang and cooperated with her to steal smallpox vaccination techniques. As a result, Ye Zhen caused him to be expelled from the Imperial Hospital.

This made it much more difficult for him to act as before, and he was severely punished by Prime Minister Li.

Upon receiving the order, he personally went to the Su family and asked Su's second uncle to send a letter to Ye Zhen.

Little did he know that at that moment, Ye Zhen was at the Su family home, watching the old imperial physician Su slowly awaken...
