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

In the pavilion on the artificial hill, Qin Yan was still trying to persuade Su Zhan to entrust Su Yan with his care for the rest of her life.

With the help of the system, Su Yan had already evaded several young men who were specifically chasing after her.

Only when Qin Yang approached did Su Yan emerge from the artificial mountain cave where she was hiding, and sit in the pavilion by the pond, clutching her chest and breathing slightly heavily.

At this moment, the delicate and frail beauty of Xi Shi was brought to its fullest expression, allowing Qin Yang, who had come looking for her, to feel her frail and pitiful aura even though he couldn't see her face clearly from the opposite side of the pond, which was six zhang away.

This involuntarily stirred a feeling of pity in his heart.

Walking around the pond from the corridor beside it, Qin Yang stopped beside Su Yan and asked softly, "Princess Chang Le, are you feeling unwell?"

"You are...?" Su Yan looked up, stood up and studied his appearance for a moment before remembering who he was. "Greetings, Prince of Chang'an."

Qin Yang quickly reached out to support her arm, preventing her from completing the curtsy. "Chang Le is considered a sworn sister by the Emperor, so I am also Chang Le's sworn brother. We are all family, so there is no need for such formalities."

Su Yan seemed shy about his touch, and a faint pink blush rose on her cheeks.

She lowered her head slightly, lifted her arm from Qin Yang's palm, took a step back, and completed the curtsy. "Etiquette must not be neglected. Even among family members, brothers and sisters should greet each other."

After getting up, Su Yan asked softly, "This place is secluded and quiet. Did Your Highness come here to find some peace and quiet? Or did you get lost and wander into this place by mistake? Would you like Chang Le to send someone to guide Your Highness back to the banquet?"

"The banquet was noisy and crowded, and I felt a bit stifled, so I came here to find some peace and quiet."

"Just now I saw Chang Le pressing her chest and looking uncomfortable. Is Chang Le sick?" Qin Yang's eyes were full of concern, and he showed no sign of scheming.

Su Yan followed his words and described her physical condition, "I'm not sick, it's just that my body is weak and I feel very tired after walking just a few steps."

"I remember that when Chang Le was a child, her body was not this weak. But she was poisoned too deeply back then, which damaged her health?"

When Qin Yansu was poisoned, they returned to Kunjing overnight and announced the appointment of Changsheng Wang as crown prince in the morning court session. They even threw the evidence in Changsheng Wang's face.

Su Zhan knelt down and begged Emperor Yongchang to punish Changsheng Wang in order to seek justice for his only sister.

Therefore, everyone in Kunjing knows that Su Yan was also poisoned by a strange poison, just like Qin Yan and Su Zhan.

They also knew that she had left alone in order to leave the antidote for Su Zhan.

Qin Yang wanted to know if this was true.

If that's true, then based on what he knows about Qin Yan, he would definitely feel extremely guilty towards Su Yan and would definitely try his best to make it up to her.

Moreover, Qin Yan wouldn't be very wary of her.

Perhaps he really can use Su Yan to scheme against Qin Yan!

Su Yan pretended not to know Qin Yang's guidance and nodded in agreement, "Back then, that poison put me on the verge of death. I survived entirely thanks to my master's superb medical skills. I would never have dared to hope to restore my body's foundation."

"Your master?"

"Yes, my master is He Qianji, the master of Wan Du Valley."

Back then, in order to leave the antidote for my brother, I left alone at night. When I reached the edge of the cliff on the mountain, my master stopped me and said that he had a way to temporarily save my life, and asked if I wanted to come with him.

Fearing that my hopes would be dashed, I left with my master without leaving a single word for my brother.

Over the years, I've been unable to leave the Valley of Ten Thousand Poisons because of the poison in my body, and I haven't dared to write to my brother to tell him I'm still alive, fearing that the next attack of the poison will prevent me from opening my eyes again, causing him grief once more.

Speaking of these sad things, Su Yan's eyes welled up with tears. She gently dabbed at the corner of her eye with a handkerchief and smiled somewhat apologetically at Qin Yang, "Chang Le was rude."

She deliberately let Qin Yang know that she had given up the antidote back then and that she hadn't been doing well all these years.

Qin Yang understands Qin Yan and can deduce from these events that Qin Yan and Su Zhan feel indebted and guilty towards her, and that they are very tolerant of her.

Knowing that she could get close to Qin Yan, Qin Yang would definitely try to get close to her, gain her trust, and then use her to harm Qin Yan.

Sure enough, Qin Yang smiled and said, "It's alright. Chang Le has suffered a lot these past years. Now that she's back in Kun Jing, she hasn't had a chance to explore the city yet, has she?"

My elder brother is a wise and capable ruler, skilled in both literature and military affairs. Under his rule, Kunjing is much more prosperous than it was eight years ago.

"I'm a rather idle man, and I often wander around when I have nothing to do. I know Kunjing very well. How about I come to pick you up tomorrow and take you around Kunjing?"

"Wouldn't this... be too much trouble for Your Highness?"

"No trouble at all, it's my honor that Chang Le would ask me to accompany her." Qin Yang looked extremely honored.

If Su Yan hadn't known what kind of person he was from the plot, she probably would have been fooled by him just by looking at his appearance.

Su Yan hesitated for a moment before asking, "But what if the Princess of Chang'an minds?"

"You are my brother's adopted sister, which means you are also my adopted sister. Why would she mind if her brother took her shopping and sightseeing?" Qin Yang said nonchalantly.

Su Yan looked persuaded and looked at Qin Yang with joy and anticipation, "Then Chang Le will thank Your Highness in advance."

"If Chang Le really wants to thank me, then let me show you around the whole of Kun Jing. Being able to accompany such a beauty as Chang Le on a shopping trip, all the young men in Kun Jing will probably be green with envy!" Qin Yang teased her with a smile.

Su Yan blushed in response, her lips curving upwards involuntarily.

As the saying goes, a beautiful woman's smile can topple a city, and a second smile can topple a nation. Qin Yang was dazzled by her shy smile.

I couldn't help but bring up some funny stories that had happened to Kunjing, deliberately trying to make her laugh.

He was quite humorous and witty, and Su Yan found it quite amusing. She didn't need to act much; she was naturally amused.

Qin Yan finally managed to get Su Zhan to stop preventing him from seeing Su Yan. When he arrived, he saw Su Yan and Qin Yang chatting happily. There was no trace of sadness or haggardness on her face. Instead, her bright smiles added a touch of radiance to her brows.

Even from a distance, you can tell she's in a great mood!

"Host, look at Qin Yan's face right now, it looks terrible!" The system relayed Qin Yan's current expression to Su Yan.

His face was darker and more somber than the seawater in the night.

It was so gloomy it was almost dripping with water.

Su Yan glanced at him with her consciousness, then withdrew it and focused on talking to Qin Yang, looking at him intently with admiring and curious eyes.

This not only made Qin Yan, who was not far away, extremely jealous, wishing she could rush over and kick Qin Yang away, and take over all of her attention.

This made Qin Yang's heart flutter, and he felt that she had fallen for him, which was why she kept looking at him like that.

Qin Yang was extremely pleased that such a stunning beauty had so easily captured his heart, and his heart was racing uncontrollably.

He gazed back at Su Yan with deep affection, causing her cheeks to flush red, and she lowered her head shyly.

Seeing Qin Yang reach out to touch Su Yan's face, Qin Yan could no longer hold back and strode over, calling out, "Ayan!"

Upon hearing his voice, Qin Yang's heart tightened. He stopped trying to tuck Su Yan's stray hairs behind her ear, turned around, and respectfully bowed to him while calling out "Royal Brother."

Therefore, Qin Yang did not see Su Yan behind him, whose face turned pale and whose eyes were filled with tears when she saw Qin Yan.

Qin Yan only had eyes for Su Yan, and casually said to Qin Yang, "No need for formalities. I have something to discuss with Su Yan. You may leave."

"...Yes, Your Majesty, I shall take my leave." Qin Yang wanted to stay and see how Qin Yan treated Su Yan, but he could tell that Qin Yan would never let him stay, so he could only suppress his resentment, bow, and take his leave.

After Qin Yang's figure disappeared around the corner of the corridor, Qin Yan took two steps closer to Su Yan.

He took a step forward, and Su Yan followed with a step back, stubbornly trying to keep her distance from him.
