He was on his southern tour that day and was unaware of the matter, so he could only ask his fourth brother, who was present at the time.

But he also had a question in his mind: why did his fourth brother happen to be there as well?

It's not that I doubt my fourth brother, but I just have a feeling that this matter is not simple.

Last night I was so busy with our lovemaking that I forgot to ask Heyue. I decided to ask Fourth Brother this morning.

No matter who the other party is, he will not let them off easily and will avenge He Yue.

"That day it was the ninth and tenth brothers who did it. They deliberately used Heyue's handwriting to lure me there. When I got there, Heyue was already unconscious, but fortunately she was alright."

Prince Yong frowned, but did not hide it from him. He made a point of explaining the last sentence, worried that Thirteen might overthink it.

Thirteenth Prince paid no attention to those words. Upon hearing that it was the Tenth Prince, he leaped up in a rage like a lion with its mane bristling, slamming his fist on the table: "What does this Tenth Prince want? Could it be that he still has his eye on Heyue?! I'm going to teach him a lesson and avenge Heyue!"

After saying that, he strode out.

Prince Yong shouted sternly, "Come back here!"

Thirteen reluctantly sat back down, poured himself another cup of tea, and gulped it down.

"Why are you still so impulsive? Even if you go, what good will it do? Are you afraid that others won't know that He Yue was drugged?"

Upon hearing his words, Thirteen Jun's face stiffened, and he looked annoyed, but his irritable mood gradually subsided.

Seeing that he had calmed down, Prince Yong's expression softened a bit: "Since this matter is resolved peacefully, there is no need to pursue it further."

"Is this how it's going to end? I'm not reconciled!" the Thirteenth Prince demanded through gritted teeth.

How could he easily let go of the rift between him and Heyue, who had almost been harmed?

Moreover, Lao Shi's feelings for He Yue were obvious. He dared not imagine that if Lao Shi had done anything to He Yue back then, he would have killed him without being able to resist.

What were Lao Shi's intentions when he drugged He Yue? Even if He Yue is unharmed, it doesn't guarantee that he didn't have that intention.

"This concerns the reputation of Heyue, and brothers must not kill each other," Prince Yong reminded him in a low voice.

Thirteen was speechless, then sneered: "I can't do anything to them openly, but I'll teach them a lesson in secret!"

In short, this feud has been formed.

“You don’t need to worry about it. Do you know that the Ninth Prince was ill and didn’t go out for a long time?” Prince Yong suddenly changed the subject, with a half-smile.

Thirteen was taken aback, confused: "What does Fourth Brother mean by this?"

Prince Yong smiled faintly: "At that time, his illness was manifested on his face. Ninth Brother cares most about his face. He Yue has never been one to suffer a loss. This matter is probably related to He Yue."

Thirteen chuckled. This method, without a doubt, was meant to be amiable.

But why did she let the tenth brother go?

My heart, which had just soared, instantly sank, and the suppressed bitterness began to resurface.

When Eighth Sister-in-law tried to matchmake Heyue with Tenth Brother, Heyue didn't refuse. Even with Eighth Sister-in-law's influence, didn't Heyue also have feelings for Tenth Brother?

Could it be that you can't bear to do it?

However, it was not easy to talk about this with her fourth brother, so she had no choice but to suppress her displeasure.

"How could they know Heyue's handwriting?" After calming down, Thirteen was puzzled again. Suddenly, a thought flashed through his mind, and he frowned and asked, "Was Eighth Sister-in-law involved in this?"

"There is no evidence for this matter, and we do not know yet. However, Guo Luoluo is not a simple person. I used to think that she was arrogant and domineering, only knew how to fight and hang out with men. But since she married into the Eighth Prince's family, I have found that many things are not as I imagined."

Aside from the fact that she often went out riding and hunting with some of the Eight Banners princesses when she was young, and that she was very harsh on her servants, there were many things about her that my people didn't know. All we knew was that my eighth brother doted on his wife after their marriage.

"But the Eighth Brother's actions over the years are inconsistent with his past behavior. He seems to be deliberately targeting you and me, while he has become less accommodating to the Crown Prince's difficulties." The Fourth Prince shook his head, utterly puzzled by the matter.

Thirteen snorted: "Heyue and Eighth Sister-in-law have always been close. It wouldn't be difficult for Eighth Sister-in-law to recognize Heyue's handwriting. I think it's very likely that this was her idea." He then gritted his teeth: "Heyue treated her like a sister, yet she treated Heyue like this. She's just like Eighth Brother!"

"The Eighth Prince appears gentle and refined on the surface, but he wins people's hearts everywhere. The Ninth and Tenth Princes also follow his lead. His ambition to seize the throne is obvious. If it really was the work of the Guo Luo Luo clan, it must have been the Eighth Prince's idea. His purpose in framing me and He Yue back then is self-evident." Prince Yong pondered for a moment and sighed.

"Why are they targeting you and me instead of the Crown Prince? Do they really think we brothers are so easily provoked?" Thirteen said discontentedly.

Prince Yong sensed the deeper meaning in his words and glanced at him.

Thirteen knew he couldn't hide it from his fourth brother, so he told him about the guard. He then smiled bitterly and said, "I have always respected the Crown Prince with all my heart, but I never expected him to treat me so kindly and amiably, disregarding any brotherly affection. It's really laughable."

"Under no circumstances should you harbor any resentment towards the Crown Prince. You must understand that as the Crown Prince, there are many things you cannot do. Let this matter rest here." Prince Yong warned solemnly, his brows furrowed.

Thirteen nodded: "I know what's important and won't fall out with the Crown Prince because of this. After all, apart from this matter, he has always been very good to us, much better than Eighth Brother and the others. There's just one thing I've never understood."

"Go on," Prince Yong nodded in agreement.

"I don't know why, but Heyue always seems to treat Eighth Sister-in-law differently. If we're talking about compatible personalities, Eighth Sister-in-law has repeatedly targeted Heyue and me. Heyue is usually very vengeful, but she's so tolerant of Eighth Sister-in-law." Thirteen frowned in confusion.

"What do you want to say?" Prince Yong also had this feeling and had reminded Heyue more than once, but she insisted on going her own way.

That girl was too stubborn. She would agree readily on the surface, but in the blink of an eye, she would go back to her old ways, which gave him a great headache, yet he couldn't bear to be too harsh on her.

“I won’t let Heyue and Eighth Sister-in-law continue like this, but Heyue is always stubborn. If I try to persuade her, she will definitely not listen.” Thirteen pouted: “Sometimes I feel that she cares more about Eighth Sister-in-law than about me.”

"What kind of jealousy are you having now?" Prince Yong asked, amused.

Thirteen blushed: "What a joke! I'm not jealous, I'm jealous of a woman..."

Suddenly, a thought struck him, and his face darkened instantly: "Fourth Brother, do you think it's possible that Eighth Sister-in-law is targeting me and Heyue not because of you and me, but because..."

The rest of the words seemed difficult to say, but the thought of this answer made his face darken, and he seemed to be gritting his teeth.

Prince Yong was initially puzzled, but upon seeing his expression, his heart stirred, and he pondered for a moment: "It's not impossible."

Then, finding the matter too absurd, she changed the subject, wanting to advise him not to overthink things. But she saw that Thirteen's face had turned ashen. He suddenly stood up and paced back and forth, his expression of gnashing his teeth suggesting he wished he could tear someone to pieces, accompanied by muttering to himself.

"I absolutely cannot let Heyue associate with her again, I absolutely cannot let Heyue get involved. That Eighth Prince, how come he doesn't know how to keep an eye on his wife? Doesn't he realize something is wrong? He's really carefree!"

Prince Yong sighed helplessly. This thirteenth brother of his really was jealous of everyone.
