I fulfilled the female supporting role's wish and I succeeded

As night fell, the capital of Dai State was shrouded in an oppressive silence. The streets were deserted, save for the occasional patrol of soldiers, their heavy footsteps echoing in the empty night.

Su Luo's mansion was brightly lit.

In the study, Su Luo sat at her desk, the flickering candlelight illuminating her cold face. She held a secret letter in her hand, reading it over and over again, her eyes deep, as if filled with a thousand words.

"Your Highness, everything is ready." A man in black appeared silently in the study, knelt on one knee, and reported respectfully.

Su Luo slowly put down the secret letter, raised his eyes to look at the man in black, and said in a calm and cold voice: "Very good. Remember, make sure everything is foolproof."

"I understand." The man in black responded in a deep voice, and then disappeared into the darkness, as if he had never appeared.

Su Luo stood up and walked to the window, looking out at the dark night sky, her mind racing. She knew that after tonight, Dai would cease to exist, and she, too, would have to return to Yan.

At the same time, there was singing and dancing in the palace of King Dai.

The King of Dai sat high on his throne, holding his beautiful concubine in his arms, admiring the graceful movements of the dancers in the palace. He was immersed in wine and women and was completely unaware of the approaching danger.

"Report——"

Suddenly, a guard stumbled into the hall, shouting in fear: "Your Majesty, this is bad! The Yan State... the Yan State army is attacking!"

Upon hearing this, the King of Dai dropped the wine glass in his hand to the ground with a loud bang, shattering it. He stood up abruptly, his face turning pale in an instant: "What?! This... How is this possible?!"

"Your Majesty, it's true! The Yan army has broken through the city gate and is heading towards the palace!" said the guard in a trembling voice, his eyes full of fear.

The King of Dai felt dizzy and almost fainted. He could never have imagined that Yan would suddenly attack Dai and break through the city gates so quickly.

"Quick! Go and mobilize the Royal Guards to protect the palace!" King Dai shouted in panic, his voice trembling.

However, it was too late.

The Yan army surged into the palace like a tide, leaving rivers of blood and corpses everywhere they went. The Dai soldiers were unable to resist and were forced to retreat.

The King of Dai fled in panic under the protection of his guards, but he was eventually surrounded by the Yan army and had no way to escape.

"King Dai, surrender!" A cold shout was heard, and Su Luohan appeared in front of King Dai with a long sword in his hand.

The King of Dai looked at the Princess of Yan before him, his eyes filled with despair and anger: "Princess Zhaoyang, you...you said you wouldn't take my life!"

Su Luo smiled coldly: "That was in the past, but it's no longer necessary now. He who knows the current situation is a hero. King Dai, your luck has run out, so you'd better surrender obediently!"

The King of Dai sighed to the heavens, knowing the situation was hopeless. He slowly drew the sword from his waist and placed it across his neck. A gleam of determination flashed in his eyes: "I... will never surrender!"

Before he could finish his words, he wiped it hard, blood spurted out, and his body fell to the ground with a bang.

The fall of the Dai Kingdom's palace marked the complete demise of the Dai Kingdom.

Outside the city, inside the camp of the Yan army.

Xiao Heng, dressed in military uniform, stood in front of the sand table, his eyes fixed on the map of the Dai State's capital.

"General, the palace of the King of Dai has been taken, and the King of Dai has committed suicide." A general walked in quickly and reported.

Xiao Heng nodded slightly, his face not showing much joy. He knew that this was just the beginning, and there were more difficult tasks waiting for him.

"Pass the order down, pacify the people, strengthen the city defenses, and do not disturb the people." Xiao Heng ordered in a deep voice.

"Yes!" The general took the order and left.

Xiao Heng turned around and looked out the window at the dark night sky, his mind racing. He knew the day he would reunite with Sister Wan Ning was getting closer.

A few days later, at the post station in the capital of Dai State.

Xiao Heng was dressed in casual clothes, standing in front of the mansion gate, looking at the familiar scene in front of him, with a lot of emotions in his heart.

"Your humble servant greets Princess Zhaoyang. I am late and the princess has suffered." Xiao Heng walked into the mansion and saw Su Luo. He immediately knelt down and saluted, with a hint of excitement and guilt in his voice.

Su Luo stepped forward to help Xiao Heng up. Looking at the heroic man in front of him, a trace of relief flashed in his eyes. Under the watchful eyes of the crowd, it was not the right time to reminisce about the past. "General Xiao, please stand up quickly."

Xiao Heng stood up and looked at Su Luo gently, as if he had a thousand words to say.

Su Luo took Xiao Heng back to his residence and dismissed his attendants.

"Sister, I'm sorry." Xiao Heng couldn't hold back any longer and hugged Su Luo tightly, tears welling up in his eyes. Over the years, he had missed Su Luo constantly and worried about her safety. Now, finally reunited, he could no longer suppress the excitement and guilt in his heart.

Su Luo gently hugged him back, patted his back soothingly, and said softly, "It's all in the past. This is my choice, and it has nothing to do with you." She paused, then smiled and joked, "How come the dignified General Xiao has become a little crybaby now?"

Xiao Heng burst into laughter, let go of Su Luo somewhat embarrassedly, and wiped the tears from the corners of her eyes.

"Sister, have you been doing well these years?" Xiao Heng asked with concern.

Su Luo smiled slightly: "I'm fine. As for you, I heard that you are now a general of Yan State. That's really amazing."

Xiao Heng smiled, a hint of pride flashing in her eyes: "This is all thanks to my sister. If it weren't for your guidance and cultivation, I wouldn't be able to achieve what I have today."

Su Luo shook his head: "Your achievements are the result of your own efforts. I just did what I should do."

The two chatted for a long time, telling each other about their experiences and thoughts.

"Xiao Heng, I'll take you to meet two people." Su Luo suddenly said, with a hint of mystery in his eyes.

Xiao Heng was a little confused: "Who is it?"

Su Luo didn't answer, but just took his hand and walked out of the room.

They came to a secluded courtyard and saw two familiar figures standing in the courtyard, looking forward to it.

"Father, Mother!" Xiao Heng shouted excitedly.

They were Xiao Heng's parents, Xiao Minghan and his wife.

"Heng'er!" Xiao Minghan and his wife came forward excitedly, hugged Xiao Heng tightly, tears streaming down their faces.

Xiao Heng had never imagined his parents, long deceased, would suddenly appear before him. He was filled with surprise and self-blame. For so many years, he had always believed his parents were gone, and his heart was filled with guilt and regret. Now, to see them again, he was overwhelmed with emotion.

"Father, Mother, I am an unfilial child and have caused you to suffer." Xiao Heng said with a sob.

Xiao Minghan and his wife shook their heads, their eyes filled with love. "Heng'er, as long as you are safe, we are satisfied. We have been waiting for you all these years."

The family hugged each other tightly, expressing their longing and joy for each other.

Su Luo stood aside, watching this heartwarming scene, and felt a warmth in her heart. She knew how precious and important this moment was to Xiao Heng.

"Sister, thank you." Xiao Heng walked up to Su Luo and said gratefully.

Su Luo smiled slightly: "No need to thank me."
