The speed of the Imperial Family's Celestial Secret Guard was not something that ordinary dark guards could compete with. No matter what, Xiao Jiu'an was the only one capable of catching up to the three Celestial Secret Guards, who had already left the Prince Yanbei's Mansion's guards and dark guards far behind.

Although he wanted to know why they went after her, he did not want Ji Yunkai to die under the hands of the Imperial Family's Celestial Secret Guard.

"Another assassin?" Ji Yunkai, who was still lying on the ground but did not dare to fall asleep, was so scared that she jumped up when she heard the commotion. She was still holding onto the Heavenly Doctor's Divine Needle that Feng Qi had given her.

Right now, staying inside was not safe. If an assassin were to enter, she would not even have a place to run to; however, going outside would not be safe either.

As she held onto the Heavenly Doctor's Divine Needle, Ji Yunkai secretly cursed in her heart and stood behind the door. Hearing that the assassin stopped, she mustered up her courage to open the door.

However, Ji Yunkai did not dare to go out and only hid behind the door instead. She secretly stuck out her head and looked out. Ji Yunkai was dumbfounded as she said, "Xiao Jiu'an?"

Wasn't Xiao Jiu'an not here? Why did he suddenly appear? He even helped her and stopped the assassin?

If Xiao Jiu'an was not in Prince Yanbei's Mansion two hours ago, it would be normal for him to return now.

"With Xiao Jiu'an here, I feel at ease." Ji Yunkai heaved a long sigh of relief.

She was someone who had seen how abnormal Xiao Jiu'an was, so there was nothing to be afraid of as long as Xiao Jiu'an was here.

Seeing the four people fighting outside the courtyard, Ji Yunkai decided to continue hiding after a moment of hesitation, to not cause trouble for Xiao Jiu'an.

But when Ji Yunkai wanted to hide, the Imperial Family's Celestial Secret Guard did not give her the chance. Not long after, the other four flung away from Prince Yanbei's Mansion's guards and dark guards and chased after her.

The Celestial Secret Guards had gathered again, but this time their target was not Xiao Jiu'an, but Ji Yunkai.

The other four Celestial Secret Guards looked at Xiao Jiu'an and pounced at Ji Yunkai. Xiao Jiu'an originally wanted to stop them, but he heard one of them say, "Be careful of the Heavenly Doctor's Divine Needle!"

Heavenly Doctor's Divine Needle?

Ji Yunkai had the Heavenly Doctor's Divine Needle with her; Sky Doctor Valley truly valued her.

The Emperor must be here for the Heavenly Doctor's Divine Needle, but how did the Emperor know that Ji Yunkai had them?

He did not even know about this!

*Puff! Puff!*

Ji Yunkai hid behind the door, seeing the assassins pouncing toward her, she did not hold back and pressed down on the Heavenly Doctor's Divine Needle. A series of nine golden needles flew out, forcing the four Celestial Secret Guards to retreat.

Not even Li Yuan could withstand the might of the Heavenly Doctor's Divine Needle, let alone them.

As the four of them retreated, Xiao Jiu'an knew what the Emperor had sent them to do, and he did not hold back anymore. The moment the four of them retreated, Xiao Jiu'an welcomed them with his sword.

*Pfft!* With a single sword strike, he had cut a Celestial Secret Guard into two halves.

Blood and brain matter immediately burst out, splattering all over the ground.

Although this was not the first time she had seen such a gory sight, Ji Yunkai could not help but feel her scalp tingle.

Xiao Jiu'an was simple and brutal when he killed people. He did not have a single sense of beauty, and it was truly hard to appreciate.

He then turned around, and the sword in his hand swung toward another person. Although they dodged very quickly, Xiao Jiu'an had still slashed him in the middle with his blade. It was not fatal, but it caused him to lose the ability to fight.

"Kill!" When the remaining five Celestial Secret Guards saw the situation, they did not have any intention to retreat but instead intended to fight. Prince Yanbei's Mansion's guards and dark guards rushed over and saw their Prince fighting one against five, with no effort at all.

However, now was not the time to admire the noble demeanor of their Prince. An injured Celestial Secret Guard was lying on the ground, and with the principle of taking advantage of your enemy's weakness to take his life, the guards and dark guards attacked and killed him.

The Celestial Secret Guard's eyes were wide open as if he could not believe that a mighty Celestial Secret Guard would die in the hands of a bunch of ordinary guards.

They had lost two of their companions in such a short period. No matter how resolute the heart of the Celestial Secret Guard was, they could not help but waver at this moment.

It had to be known that ever since they became Celestial Secret Guards, they had never failed in any of their missions. The seven of them had never changed missions even once.

It was the first time they had anyone, two at that.

The remaining five people felt like retreating. They looked at each other in tacit understanding. Without saying anything, the five of them backed off at the same time.

"Retreat!" The five of them disappeared in the blink of an eye like ghosts. Just as the dark guards were about to give chase, they were stopped by Xiao Jiu'an, "You guys aren't their match!"

The Imperial Family's Celestial Secret Guard was not just for show, you know.

They had failed more than once tonight.

"You guys are useless!" Seeing the strength of a Celestial Secret Guard, Xiao Jiu'an was shocked to realize that his opponent was too lenient and that the level of training for his dark guards was too weak. If not, how could he be lagging behind the Imperial Family's Celestial Secret Guard by so much?

If the dark guards knew what Xiao Jiu'an was thinking, they would vomit blood.

But even if they vomited blood, it would be useless. Because Xiao Jiu'an then said, "Go back and intensify your training. This King does not wish for the same thing to happen again."

"Yes." The dark guards replied. They felt like vomiting blood, but no one dared to express their dissatisfaction.

Today, they saw the disparity between themselves and the Imperial Family's Celestial Secret Guard. If they did not want to die, they had to desperately train and become stronger.

After instructing the dark guards, Xiao Jiu'an withdrew all of them and said coldly, "Ji Yunkai, come out!"

"Your Highness," Ji Yunkai walked out from behind the door, her hands still holding onto the Heavenly Doctor's Divine Needle, but she did not dare point it directly at Xiao Jiu'an.

Seeing Xiao Jiu'an's cold face, Ji Yunkai carefully asked, "Did they come for me?"

From the looks of it, she had wrongly blamed Xiao Jiu'an before. The assassins today all seemed to have come for her, but for what?

"Otherwise, are they here for This King?" This woman knew how to cause trouble. If he had not arrived in time, this woman would have died.

So what if she had the Heavenly Doctor's Divine Needle? The Heavenly Doctor's Divine Needles were not limitless, and once they were used up, would Ji Yunkai still be able to live?

"Who knows that you have the Heavenly Doctor's Divine Needle?" Feng Qi had been very good to Ji Yunkai. He was even willing to give her the Sky Doctor Valley's Valley Master's Treasure.

"Feng Qi, Fei Xiao Chai, and the people from the Duke Palaces as well as the assassin who escaped earlier." Ji Yunkai accidentally swept a glance at the body that was split into two and quietly shifted her gaze away.

Xiao Jiu'an's way of killing was too brutal. Not only was the floor covered with blood, their intestines and organs were also littered on the ground. How was she supposed to sleep at night?

"The assassin who escaped earlier?" Xiao Jiu'an did not know about the matter of an assassin infiltrating Prince Yanbei's Mansion previously.

"In reply to Your Highness, the matter is like this..."
