The Fourth Prince looked at the Crown Prince, and he felt that his Second Brother's thoughts seemed to be different from his own.

“Yes, He Xue is the little sister we watched grow up, we must protect her! We can’t let anyone bully her!” the eldest prince said.

The Crown Prince and the Fourth Prince both looked at the First Prince.

"What's wrong? Did I say something wrong?" the eldest prince asked, scratching his head.

"It's alright!" the Crown Prince said. His elder brother was really too simple-minded; he was better suited to leading troops into battle.

"I was trying to figure out what my second brother meant, but my eldest brother ruined it all with just one sentence!" The fourth prince looked helplessly at the eldest prince.

"If it really was Suo'etu who sent people to harm He Xue, then Suo'etu is really too powerful, he has even extended his reach into the palace."

But why would Suo'etu want to harm Hexue? Hexue doesn't seem to have met him more than a few times, does she? The eldest prince was completely baffled.

After listening to the First Prince's words, the Fourth Prince rested his chin on his hand and began to ponder.

The Crown Prince glanced at the First Prince and the Fourth Prince, but said nothing. He was determined to find Suo'etu himself and get to the bottom of things.

"Could it be because of Suhetai?" This was the only reason the eldest prince could think of.

"But Uncle and Suo'etu don't seem to have any conflict, do they?" The Fourth Prince felt that the First Prince's statement was untenable. If He Xue were Mingzhu's daughter, he could believe this excuse. After all, who in the entire court didn't know that Mingzhu and Suo'etu were at odds?

"Second brother, the most crucial issue now is that if it really was Suo'etu who caused Hexue's death, I'm afraid Father Emperor wouldn't punish Suo'etu too severely!"

Although Father Emperor usually treats He Xue fairly well, compared to the fate of the nation, no one is worth mentioning in front of Father Emperor. "The First Prince didn't say something: Suo'etu is the Crown Prince's man, and Father Emperor will definitely not touch the Crown Prince's man."

If we touch Suo'etu, Mingzhu will probably incite him again, and he won't have any peace.

The Crown Prince knew that what the eldest prince said was true; at least for now, his father, the Emperor, would not punish Suo'etu.

Moreover, given Suo'etu's cunning, he wouldn't easily confess. Just because his disciple went to see Physician Liu, does that mean he was the one who harmed Xue?

“I know who can deal with Songgotu!” the Fourth Prince said.

"Who is it?" the eldest prince asked curiously.

"Uncle! If Uncle finds out, he definitely won't let Suo'etu off the hook!"

"That's right, how come I didn't think of that!" the eldest prince said excitedly. Given how much Suhetai doted on Hexue, he certainly wouldn't let Suo'etu get away with it.

"But we can't be sure if it's Suo'etu right now. What if we wrongly accuse Suo'etu?" If Suhetai beats Suo'etu because of their suspicions, Suhetai will not have a good outcome either.

"Brother, don't worry. Although Su Hetai is a military general, he is shrewd despite his rough exterior. He will investigate things himself!" the Crown Prince said.

"That's fine!" the eldest prince said with relief. Suhetai was a general who protected the peace of the Qing Dynasty, and he could not be punished for such a trivial matter.

"Let's go find Father Emperor now. While Jing Shu is here, we'll report the results of our investigation to him! I'm sure Jing Shu will relay the information to Su Hetai!" the Crown Prince said.

"Alright, go quickly!" the eldest prince urged.

The three princes arrived at the princes' quarters, and the prince handed over his confession to Emperor Kangxi.

Emperor Kangxi glanced through the confession and asked, "Wu Guozhu is a member of the Imperial Household Department?"

"Your Majesty, yes! When He Zhu went to the Imperial Household Department to arrest him, Wu Guozhu had already committed suicide! Your Majesty, I have sent Ling Pu to investigate the cause of Wu Guozhu's death!"

Kangxi nodded. The Imperial Household Department was under the Crown Prince's jurisdiction, and this matter should not be related to the Crown Prince.

"Father, I have something to say!" the Fourth Prince stepped forward and said.

Kangxi looked at the Fourth Prince with an ambiguous expression. The Fourth Prince kept his head down, and Kangxi couldn't guess what the Fourth Prince was going to say. Was he going to ask him to investigate this matter? Wasn't the Fourth Prince the closest to the Crown Prince? Why would he want to undermine the Crown Prince at this time?

"Fourth Prince, come down here and say what you have to say! Go and see He Xue first!" Kangxi tried to change the subject. It was better to talk about this privately, after all, Jing Shu was still here!

"Father, what I have to say is related to He Xue's injury!" the Fourth Prince insisted.

Kangxi glared at the Fourth Prince, thinking, "He really has no sense of propriety at all. Didn't he see me giving him a meaningful look?"

"Father, is your eye twitching?" the eldest prince asked with concern.

Emperor Kangxi was truly angered by his eldest and fourth sons; they were both just trying to provoke him. Kangxi said weakly, "I'm fine!"

"Father, please let the fourth prince speak!" said the eldest prince.

At this moment, Kangxi really didn't want to look at the eldest prince; he was afraid he would lose control and hit him.

"Fourth brother, hurry up and speak! Father is waiting!" the eldest prince urged the fourth prince.

Looking at his eldest son, who was so eager, Kangxi couldn't help but wonder if his impetuous son had some ideas in mind.

Without waiting for Kangxi to speak, the Fourth Prince repeated to Kangxi what he had said to the Crown Prince earlier.

"Song'etu?" Kangxi thought to himself, how did this matter get involved with Song'etu again?

Kangxi then looked at the eldest prince. Had the eldest prince been involved in this matter?

He could usually turn a blind eye to the discord between Suo'etu and Mingzhu, but if they really wanted to incite his sons to fight for the position of crown prince, he would not be lenient.

Recently, influenced by He Xue, he felt that the relationship between Suo'etu and Mingzhu was abnormal, and he was happy to watch them bicker.

Jing Shu, who was standing nearby, naturally heard what the Fourth Prince said. He could roughly guess the purpose of the Fourth Prince saying this in front of him. It seemed that this matter needed to be reported to his father so that his father could investigate whether it was related to Suo'etu.

The more Kangxi thought about it, the more chills ran down his spine. If it really was Suo'etu, then Suo'etu's influence had reached into the palace, and he was able to kill people to silence them in such a short time.

Will he have to sleep with one eye open and one eye closed from now on? Has he been too lenient with these people? It seems he needs to properly discipline everyone in the palace.

Kangxi's action eliminated many spies planted in the palace. Looking at the lists, Kangxi realized that he was living under the surveillance of those ministers every day.

He ordered his men to send those people directly to their master's residence, causing widespread panic throughout the court.

"Your Highness, what do you think of this matter?" Kangxi asked the Crown Prince.

"Father, we cannot determine whether this matter is related to Suo'etu based solely on my fourth brother's words."

"Your Majesty, I believe you will investigate thoroughly and will not wrong anyone, nor will you let the criminals go unpunished!" the Crown Prince said, bowing.

The eldest prince glanced at the crown prince and said, "As expected of the second prince, he's truly a dog! What he said is as good as saying nothing at all!"

Kangxi said directly to Liang Jiugong, "Summon Zhao Chang to see me!"

Emperor Kangxi decided to investigate the matter personally, and he discovered that it involved many people. The Crown Prince, Suo'etu, the First Prince, and Mingzhu were all potentially involved!

He wanted to see who was the most hidden person!
