The male lead went insane after the female supporting character gave birth to the main villain'

On the carriage back to the Prince of Zhan's mansion, Su Yan sat alone, sobbing softly.

She didn't need to cry anymore after leaving the palace, but Su Zhan was so worried about her that he wanted to ride in the carriage with her. After she refused, he rode his horse to the side of the carriage window.

If she doesn't keep crying, how can she prove her feelings for Qin Yan?

Seeing how hard Su Yan was working on her crying scene, the system told her some good news in her mind: "Host, Qin Yan just increased your favorability rating by a full fifteen points. Now his favorability rating for you has reached eighty-five, and he is only fifteen points away from one hundred."

"Host, you're amazing!"

"System, could you please influence Su Zhan to go further away? I've almost cried my eyes out." Su Yan's consciousness avatar lay listlessly on the floor of the system space.

The system encouraged her: "Host, we'll be at the War King's Mansion soon, hang in there a little longer."

To make her feel better, the system also told Su Yan some news.

It turns out that Qin Yan's insistence on bringing Chen Yilin into the palace was solely for revenge against Chen Yiyue and to control the Chen family.

Before Chen Yiyue got married, she often bullied her half-sisters at home. Only Chen Yilin, who was equally ambitious and looking for a better life while still married, was not bullied by Chen Yiyue much.

Because she was Chen Yiyue's lackey, she often snitched to Chen Yiyue, saying which half-sister was talking badly about her behind her back, and helped Chen Yiyue slap her half-sister.

In fact, those half-sisters did not speak ill of Chen Yiyue. They had just had a quarrel with Chen Yilin, which made Chen Yilin hold a grudge against them, so she slandered them to Chen Yiyue.

Chen Yilin also used Chen Yiyue's brainless arrogance to highlight her own gentleness and virtue, making the literati and scholars that Chen Yiyue admired feel some pity for her.

Eight years ago, Qin Yan did not kill Chen Yiyue after he learned that she was pregnant with Qin Ding's child. He did not kill her after he ascended the throne, and he did not even touch the child in her womb.

They simply threw her into the Changsheng Prince's mansion, imprisoning her there alongside the women in the Changsheng Prince's harem who had committed evil deeds, letting them fight like dogs.

Qin Yan has already sent those women who haven't done anything wrong to remarry.

After all, the Great Zhou Dynasty had been ravaged by war for ten years before its founding, resulting in a sharp decline in population. Eight years ago was precisely the time when the population needed to be restored as soon as possible.

Therefore, Qin Yan abolished all the ridiculous rules of the previous dynasty that widows should remain chaste for their husbands and never remarry.

In order to abolish this rule, Qin Yan set an example by taking five widows into the palace and bestowing upon them the title of Jieyu.

These five widows were all soldiers who died in battle under Qin Yan's command, and they had even given birth to the children of those soldiers.

But she had no relatives to help her, and she couldn't raise her child on her own.

Qin Yan bestowed upon them the title of concubines and allowed them to live in a suburban palace, where he assigned palace maids and eunuchs to serve them. All they needed to do was to properly raise the children they had borne for their ex-husbands.

Even the reigning emperor took widows as concubines, supported widows remarrying, and even supported widows remarrying with their children. What other man would dare to stop a widow from remarrying?

"So Qin Yan didn't just appoint four concubines, but nine?" Su Yan asked, fiddling with the hole in her system T-shirt.

The system grabbed the corner of her clothes, preventing her from buttoning it up. "Host, this is my only piece of clothing. If you ruin it, I'll have nothing to wear!"

"So what if it's broken? I'll buy you a new one once I earn enough points," Su Yan said generously.

The system dared not take her bait and carefully rescued the clothes from her clutches, saying, "We'll talk about it after you earn some points."

Getting back to the main point, the five concubines knew that Qin Yan wanted to take them as concubines in order to overthrow the old custom of widows remaining chaste for their deceased husbands. They supported Qin Yan's actions, so even though they knew that Qin Yan would not sleep with them, they were still willing to come to Kunjing.

They all care more about their own children and won't compete with the concubines in the harem for the emperor's favor. As long as nothing unexpected happens, they won't compete with you in the future.

Therefore, the host doesn't need to worry about them.

"Is Chen Yiyue still alive? Is Qin Yan keeping her alive just to get revenge on her?" Could it be that he's tormenting her while simultaneously tormenting himself, driven by hatred turned to love?

"Host, this should be impossible..."

It turns out that after Qin Yan locked Chen Yiyue in the Changsheng Prince's Mansion and waited for her to give birth, he had someone poison her. Every time the poison took effect, it would torment her to the point that she wished she could die.

Before Chen Yiyue gave birth, Qin Yan sent people to take care of her belly and told her every day what her half-sister Chen Yilin was rewarded with in the palace, who praised her, and what expensive things she ate and used.

She also sent someone to tell her every single word of the things Chen Yilin said to the maids and Qin Yan in the palace, belittling Chen Yiyue.

Chen Yiyue is now driven to a mental breakdown by her resentment, jealousy, anger, and regret.

The child she initially intended to use to humiliate Qin Yan has instead become her greatest disgrace.

Qin Yan wasn't that cruel to the child. Knowing that Chen Yiyue wanted nothing more than to strangle the child, he sent someone to take the child to Empress Jiang's palace to be raised by her.

It's possible that Qin Ding's excessive indulgence led to weak yang essence; although he had many wives and concubines in his household, very few of them became pregnant.

Most of the babies born were girls, though some boys were born, but none of them lived to the age of five.

Whether the child was simply too weak to survive, or whether the woman in the backyard used underhanded tactics, is now impossible to ascertain.

After the sudden death of the King of Changsheng, his household consisted of eight daughters and only one sickly son, who also seemed unlikely to live to adulthood.

Qin Yan sent people to look after Chen Yiyue's child, and the child is being raised quite well; it seems like he can be raised to adulthood.

Empress Jiang hated Qin Yan for killing her eldest son, and she also hated Chen Yiyue for seducing her eldest son, which drove Qin Yan mad.

But the child Chen Yiyue gave birth to was the only boy her eldest son could raise. She couldn't bear to see her eldest son die out, so she had no choice but to reluctantly take the child back to raise him.

She dared not vent her anger on that child, nor did she dare to unleash the overwhelming hatred in her heart upon him, for fear that if she killed him, her eldest son would truly be childless.

He vented all his anger and hatred towards Qin Yan on Chen Yiyue.

They ordered the servants of the Prince of Changsheng's mansion to torment Chen Yiyue day and night, satisfying her promiscuity and also taking the opportunity to humiliate Qin Yan.

After all, Chen Yiyue was still Qin Yan's deceased wife in name only. It would be bad for Qin Yan to lose face if Chen Yiyue was defiled by those lowly servants.

But to everyone's surprise, Qin Yan not only didn't care, but also ordered the soldiers surrounding the palace to make things convenient for the servants and not to go in and get involved.

"So, Chen Yiyue now has to be jealous and resentful of her half-sister every day, and is also being defiled by the servant she despises the most?"

"Yes, so Qin Yan should simply feel extreme disgust for her, without any complex emotions such as love turning into hate or hate turning into love."

At this moment, the carriage slowly came to a stop, and Su Zhan said to Su Yan through the carriage window, "Ayan, we're home!"

Outside the gates of the Prince of Zhan's mansion, Princess Fang Wanqing, accompanied by her two sons and youngest daughter, along with a large group of servants and maids, all eagerly awaited the arrival of the carriage.

Su Yan stepped out of the carriage, her swollen eyes stinging in the sunlight, and tears welled up again.

Fang Wanqing and the servants in the Prince's mansion all thought that she was crying tears of joy because she had returned home.

"Don't cry, little sister. Everything will be alright once we get home. With your brother here, no one will let you suffer." Fang Wanqing handed her daughter to the wet nurse and stepped forward to carefully wipe away her tears with a handkerchief.

Su Zhan often mentioned Su Yan to her and told her how Su Yan disappeared.

She had no doubt that if Su Yan hadn't given up on the antidote and secretly left on her own, her husband would have given the antidote to his younger sister.

Now, Su Zhan no longer exists in this world, and she would not have such a good husband and three sensible and intelligent children.

Therefore, although this is only their second meeting, she already considers Su Yan as her own younger sister.
