In order to leave the palace, Yinreng needed to ask for grace from Kangxi, so when he arrived at Yinzhi's residence, he happened to run into Nalan Mingzhu.

The moment Mingzhu saw Yinreng, her expression was obviously stunned for a moment.

Then he reacted and walked to the carriage to greet Yinreng.

"This servant greets the prince."

Yinreng's face was stern. After he got off the carriage, he said calmly,

"Get up... Lord Nalan is very caring towards you, brother. He came to comfort you right after finishing his shift."

He had a hint in his mind, but Mingzhu thought his plan was flawless, so he didn't think about it in other directions. He stood up with a sad face.

"This servant and the eldest prince have an inseparable blood relationship, so it is only natural for this servant to care about him."

"laugh……"

Listening to Nalan Mingzhu's high-sounding words, Yinreng couldn't help but sneer.

Nalan Mingzhu was confused. She looked up at Yinreng's mocking expression and felt a sudden shock in her heart.

Before I could figure out why Yinreng had this expression, Yinreng spoke again,

"Master Nalan has been at home for a few years now, and his ability to pretend has become more and more perfect. I just don't know if Master Nalan will be able to show off his pretense if Big Brother finds out..."

Yinreng really didn't have time to play along with him, so he directly exposed his hypocritical face.

Then he raised his foot and was about to walk into the mansion.

When Nalan Mingzhu heard this, he was immediately frightened.

"Prince!"

He quickly stopped Yinreng and asked with a stern face,

"What do you mean, Prince?"

Yinreng stopped and looked at Mingzhu's worried face with a half-smile.

"I've spoken so plainly, yet Lord Nalan still doesn't understand?"

Nalan Mingzhu's heart suddenly rose to his throat.

There was only one thought left in my mind -

It’s over, the prince knows.

"Lord Nalan is as hypocritical as ever. You claim to be thinking about my elder brother, but secretly you're doing something completely unscrupulous. Do you realize that you're harming the Emperor's first legitimate grandson?!"

Yinreng glared at Mingzhu with disgust, then strode into the mansion.

Nalan Mingzhu was devastated by Yinreng's words.

Although he had already prepared for the worst before taking action.

The eldest prince will find out that he is the culprit, and then he will completely break with the Nalan family, and their branch will be trampled under the feet of the other branch forever.

But he didn't expect that the matter would be discovered so quickly, and it was discovered by the prince himself.

It was completely different from what he expected.

He was petrified on the spot, letting the cold wind chill him through and through.

There were no people passing by the door of Yinzhi's residence, but there were two guards who vaguely heard the confrontation between Yinreng and Mingzhu.

The two of them were filled with shock and they secretly glanced at Mingzhu, then lowered their heads.

As servants, they knew exactly what happened in the mansion. They were wondering if it was related to the women in the harem, but they didn't expect that it was Lord Nalan who did it.

Can……

Why is this happening?

If the master has a legitimate son, he will be more respected by the Emperor. Isn't this a good thing for Lord Mingzhu?

Why would he do such a vicious thing?

The two racked their brains but couldn't figure it out.

After entering the door, Yinreng went straight to the main hall.

When the steward of the outer courtyard went to report, he stood in the corridor, frowning and thinking about how he and Yinzhi had found out about Mingzhu in their previous life.

A moment later, Yinzhi came over with a haggard face.

He stood beside Yinreng, followed Yinreng's gaze, and said nothing.

After a long while, Yinreng said,

"Any clues?"

"No……"

Yinzhi's voice was very hoarse, no longer as vigorous as before.

After the accident happened to his wife, he focused his suspicions on those in the backyard, but after interrogating them for several hours, all the concubines and servants gave him the same answer: "I don't know."

To this end, he even personally chopped two people in front of everyone and threatened them that he would find their family members and kill them, but still no one came forward to identify them.

Fu Jin was still in a coma at this moment, and his two daughters were very frightened. He was now exhausted.

Yinreng turned to look at Yinzhi and reminded him,

"Perhaps the person who has the opportunity to do this may not be a servant, but someone from outside."

"Someone outside?"

Yinzhi frowned.

"How can outsiders get in touch with Fu Jin?"

"Others may not be able to do it, but the imperial physician may not be able to do it..."

How could it be the imperial physician? Imperial Physician Chen was the imperial physician his mother usually employed. Every time he fell ill since he was a child, it was Imperial Physician Chen who diagnosed him.

This time, the concubine is pregnant very well. Doctor Chen comes to the mansion every five days. Given the relationship between him and Doctor Chen, it is impossible for him to do anything to the concubine.

The poison that caused the concubine's miscarriage was also discovered by Doctor Chen.

If he was really the one who poisoned Fu Jin, shouldn't he have disposed of the poison first?

Yinzhi was about to speak when Yinreng stopped him.

"Don't rush to refute it. Go check what happened at Doctor Chen's house recently."

After hearing what Yinreng said, Yinzhi nodded in agreement even though he thought it was unlikely.

Yinreng sighed.

"This matter is far more complicated than you think. I only hope that you can get to the bottom of it. No matter what you find, you will be more rational."

Yinzhi was in no mood to listen to Yinreng's persuasion. He just wanted to find the murderer as soon as possible and avenge his wife and his dead child.

Afterwards, Yinreng met his two nieces again, comforted them, and then said goodbye and left.

What Yinreng didn't know was that it was that one encounter between him and Mingzhu that caused Mingzhu to destroy all the evidence pointing to Soetu.

Mingzhu was really afraid that Yinzhi would find out about him, so he didn't dare to be careless at all. Unfortunately, he was a step too late to react and didn't have time to deal with Doctor Chen's family.

Yinzhi followed the ideas given by Yinreng and actually found some clues from Doctor Chen, but just when he wanted to continue investigating, all the clues were interrupted.

Just at this moment, the two guards who were on duty at the door came to find Yinzhi.

They didn't want to stand out.

Because the Crown Prince's conversation with Mingzhu that day was direct enough, they thought that His Royal Highness would directly tell his master the identity of the mastermind, but the fact was that the palace had been investigating vigorously for several days but failed to find the cause of the crime, Nalan Mingzhu.

The two men then thought of using this incident to climb up the ladder.

When Yinzhi heard that the two gatekeepers had important clues to report, he thought he had misheard.

How could the gatekeeper know what was happening in the inner house?

But he had been stuck in a dead end for a long time, so with the mentality of giving it a try, he met with the two guards.
