After traveling through time, I became a princess in ancient times

"King Nan, I failed to kill Princess Chen."

Nightingale stood in front of Ren Chennan with an expressionless face, her voice calm. She was not depressed by the failure of the assassination mission, but was extremely excited inside.

I thought Nightingale could kill that bitch, but who would have thought that such a great Nightingale would fail one day.

"Oh? How could you fail?"

It was obvious that he was very dissatisfied. The atmosphere in the study room instantly froze to the extreme, and even the air seemed to be still.

"Next time, I will kill her."

Ren Chennan glanced at Nightingale with a gloomy expression, and said coldly with impatience: "Back off."

Nightingale said nothing more, turned around and disappeared into the study, leaving only the lonely figure of Ren Chennan, with an inextricable sorrow condensed between his brows.

On the other side, Prince Chen's Palace was heavily guarded. Teams of guards shuttled through every corner of the palace, and the sound of their orderly and powerful footsteps echoed in the courtyard.

Xia Yurou stood at the window of the study, the breeze blowing her hair, her eyes fixed on the guards patrolling back and forth.

They held spears in their hands, their bright armor gleamed in the morning light, and every movement they made seemed so standardized and powerful.

"My Lord, this... is too exaggerated, isn't it?"

Xia Yurou sighed softly and turned to look at Ren Chenxi.

"Rou'er, although I have never met Nightingale, her name is known throughout the Dragon Country. She is a true cold-blooded killer. I heard that she has never failed."

After these words were spoken, the expression on Ren Chenxi's face became even more serious, and his eyes revealed a deep fear of Nightingale.

Instead, Xia Yurou smiled a little heartlessly, gently brushed away a strand of hair from the end of her hair, and said jokingly with an elegant and calm movement: "That was in the past. Wouldn't I fail if I met you now?"

Ren Chenxi frowned: "Rou'er, don't be careless. Killers like Nightingale are inhumane."

The slightly red sky outside the window is just like Xia Yurou's mood at the moment: "Although Nightingale is a killer, I don't think she is a heartless person. Often those good people who are not good at heart are not as honest as her. At least Nightingale stopped at the last moment and didn't kill me, which is enough to prove that she is not too bad. If Nightingale had a happy family, who would become a killer?"

"That being said, the world is treacherous, and the most unpredictable thing is the human heart. Nightingale is a killer, and just because you think so doesn't mean others think so. Besides, Nightingale's target is you, so we can't take it lightly."

She gently waved her hand, signaling Ren Chenxi not to be too nervous: "Your Majesty, if Yeying really wants to kill me, how can these guards in the mansion stop her? Withdraw. I don't want the atmosphere in the mansion to be too tense because of me, and I don't want more people to lose their lives because of me."

No matter what, Ren Chenxi was unwilling to withdraw his guards. After all, he couldn't feel at ease with a killer like Nightingale.

But he still couldn't overcome Xia Yurou's stubbornness. A prince was finally persuaded by a woman.

"Since you are so determined, Rou'er, I will follow your will. But you must promise me that you will be careful at all times. Your own safety is the most important thing."

Xia Yurou smiled slightly, held Ren Chenxi's hand, and said softly: "Don't worry, Your Majesty, I will be careful."

There was a hint of helplessness in his eyes, but more of it was doting and unconditional trust in Xia Yurou, and he quickly withdrew all the guards in the mansion.

On the roof, Nightingale's figure floated like a ghost. She stared at the couple leaning on each other in the courtyard below, and an inexplicable emotion surged in her heart.

Xia Yurou's words echoed in her ears. She never thought she would hear such tolerance and understanding from her target.

Nightingale took a deep breath, suppressed the emotions in his heart, and disappeared into the shadow of the roof again.

No matter how Xia Yurou viewed her, she was ultimately an emotionless killing machine. But at this moment, it seemed as if there was an indescribable warmth in her heart.

Nightingale returned to her home, which was a house hidden in a dark alley at the edge of the city. The mottled walls revealed the vicissitudes of time. There was only an oil lamp in the house, swaying quietly in the corner, casting mottled light and shadows.

A man carrying a big knife pushed the door open. He was tall and strong, and his fierce eyes made people shudder.

Looking at Nightingale sitting beside the bed, he raised a disdainful smile: "I heard that your mission failed? Is Princess Chen really as difficult as the rumors say?"

Nightingale glanced at the man coldly, disgusted and didn't want to pay any attention to him, but this guy insisted on coming up to her.

This man is known as the Knife Maniac in the underworld, and is a notorious villain in the killer world. However, he calls himself Nightingale's "ally" and often comes to disturb her peace.

"You don't need to ask about my affairs."

The Nightingale's indifferent voice was just like her name, light and cold, echoing in the dim room.

Dao Kuang was already used to her arrogant attitude. He licked his lips with his tongue and showed a lewd smile: "You are the second-ranked Nightingale in the assassin world. How can you fail like this? I will definitely help you get rid of her."

When Nightingale heard that Dao Kuang wanted to attack Xia Yurou, her calm heart suddenly became uneasy. She came to Dao Kuang in an instant and put the dagger in her hand against his throat: "If you dare to touch her, I suggest you go first."

Knife Maniac was shocked by Nightingale's fierce momentum. Fear flashed in his eyes, but was soon replaced by deep resentment.

He nodded in agreement on the surface, but his vicious eyes were fixed on Nightingale, as if he was plotting some ulterior motive in his heart.

Nightingale retracted the dagger and no longer looked at Knife Maniac.

Her back looked even more lonely in the dim candlelight, like a thorny flower blooming in the dark night.

Dao Kuang walked out of the house and spat out a mouthful of thick phlegm fiercely: "Stinky Yingzi, I will get you sooner or later."

His voice was small, but it revealed a sinister cruelty.

It was late at night and the palace was quiet.

Ren Chenxi hugged Xia Yurou and immersed himself in a sweet dream, when suddenly a cold light flashed across and broke the tranquility of the night.

The two were suddenly awakened and found a dagger tied to an envelope stuck in the bedside. The tip of the knife was trembling slightly, as if roaring softly in the darkness.

Ren Chenxi took down the dagger, and on the thin piece of paper were written the three characters "Challenge". His heart tightened, and he quickly unfolded the paper, and lines of handwriting jumped into his eyes.

The content of the letter directly challenged Xia Yurou to a duel, and asked her to go to Qiankong Mountain alone to attend the meeting. The two words "Dao Kuang" in the signature were like a curse from an evil spirit, which made people shudder.

Xia Yurou took the challenge letter from Ren Chenxi, read it carefully, and a faint smile appeared on the corner of her mouth.

"Interesting, someone actually challenged me to a fight!"

Ren Chenxi's heart sank suddenly. He didn't expect Rou'er to be so excited. Shouldn't she be showing fear?

Come to think of it, Rou'er's martial arts is far superior to his. Some masters have quirks and want to challenge opponents stronger than themselves to reach the pinnacle of martial arts.

"Rou'er, you can't go. This is clearly a trap."

Xia Yurou patted the back of his hand soothingly: "Your Majesty, since this knife maniac dares to challenge me, if I don't go, won't he look down on me?"

Ren Chenxi had heard of the notoriety of Dao Kuang. This guy was simply a killer known for his cruelty and cunning. The real intention behind the challenge letter was disturbing.

"Rou'er, I will never let you go."

She gently snuggled in Ren Chenxi's arms and shook his arm coquettishly: "My Lord, just let me go. I promise to be careful."

Ren Chenxi sighed helplessly, and gently scratched Xia Yurou's nose with his fingers, his eyes full of pampering: "You, are always so willful."

Instead, the girl whispered in his ear with a hint of sweetness: "Thank you, my lord. How can you be so kind?"

As soon as she finished speaking, Xia Yurou threw Ren Chenxi onto the bed, their hot bodies pressed tightly against each other...
