As Gu Changqing was sizing up the Palace Master, the Palace Master was also staring intently at him, lost in thought, and didn't even notice when her subordinates called her.

The man was dressed in white, with flowing black hair, a tall and upright figure, a handsome and dashing face, and a hint of unrestrained freedom in his eyes, exuding an outstanding temperament.

His entire body emanated an incomparably powerful aura, as deep and unfathomable as the sea.

"Palace Master?" The golden-armored guard called out to the Palace Master again, slightly louder, when the Palace Master did not speak.

The palace master was stunned for a moment, and said to Gu Changqing with great anger, "You are the one who killed my chief disciple?"

“That’s right, it’s me. What, you want to avenge him?” Gu Changqing said frankly and without any attempt to hide his feelings.

"Gu Changqing? Good, very good. I admire your courage and decisiveness; you do have some guts." The Palace Master said with a smile instead of anger.

"How dare you kill my chief disciple? Have you lost your mind?"

The palace master then changed his tone and said angrily.

"Hehe, I've always been bold, so I don't need to eat any gall," Gu Changqing said without batting an eye.

"You..." The palace master was immediately embarrassed and furious.

"If the Palace Master doesn't believe me, how about I give you another demonstration right in front of you?" Gu Changqing said with a slight smile, seeing that the Palace Master was too angry to speak but still maintained a calm and composed demeanor.

As he spoke, Gu Changqing continued his journey towards the Palace Master at a leisurely pace.

Under the incredulous gazes of the golden-armored guards, Gu Changqing had already walked up to the Palace Master.

Without saying a word, Gu Changqing slapped the Palace Master hard across the face, instantly unleashing the aura of an eleventh-level Immortal Emperor, with immense and surging pressure.

The terrifying pressure, like billions of miles of rivers, lakes and seas, pressed down on the entire palace, and even the void collapsed in an instant, cracking open with terrifying fissures.

Even the powerful and unparalleled Palace Master couldn't withstand this slap. She was thrown several meters down from above, and a bright red handprint instantly appeared on her beautiful face. It was red and swollen, making her look extremely disheveled.

"From now on, Yuntian Palace belongs to me, and you will be my personal concubine. If you are not convinced, I will make you submit willingly."

Gu Changqing said in a domineering yet natural manner.

The palace master stared in disbelief at the scene before him, still unable to believe that he had been slapped down, his pride shattered.

My God, what's wrong with this person? How can he be so powerful? He can send me flying with just one slap.

Heavens! I am a dignified immortal of the third level of the Immortal Emperor realm, how could I be so easily defeated by a mere mortal?

Could it be that my Immortal Emperor Level 3 cultivation is fake? Just what level of cultivation does this person possess?

Thinking this, the Palace Master carefully sensed the past and discovered that this person was actually an eleventh-level Immortal Emperor!

The eleventh level of the Immortal Emperor realm?

The palace master was stunned, his expression turned extremely ugly, a trace of panic rose in his heart, and his body couldn't help but tremble.

The guards beside him were also stunned, completely dumbfounded. Who was this person? How could even the Palace Master be no match for him?

He never imagined that one day, the high and mighty, sacred and inviolable palace master would be slapped off his throne and taken as a concubine.

Holy crap, this is like seeing a ghost in broad daylight!

At this moment, the palace master was also very angry, angry that his strength was not as good as others. Now, not only had he lost face for Yuntian Palace, but he had also lost face himself.

Although this person is handsome and dashing, and his strength far surpasses her own, she is, after all, the master of a palace in the upper realm, possessing supreme power. How could she possibly submit to a person from the lower realm, who is not even her principal wife but merely a lowly concubine?

The more the palace mistress thought about it, the angrier she became. She couldn't swallow this insult and refused to be humiliated like this.

She seemed to have made a great decision, biting her lip as she said, "No, Yuntian Palace must not give in. Although you are so powerful, I am not a lamb to the slaughter. If you think that I am a kind person who will be bullied, then you are very wrong."

"Oh, so I was wrong?" Gu Changqing asked with a playful expression, resting his chin on his hand.

"Senior, this is an outrageous insult to a junior. I will fight back no matter what," the Palace Master said, clearly displeased.

"The worst is yet to come, this is nothing," Gu Changqing said nonchalantly.

"This is outrageous! This is outrageous!"

As she spoke, the Palace Master summoned a celestial sword. The sword was crimson, as red as blood, dazzlingly bright, and exuding a terrifying sharpness. It also emitted bursts of red light from time to time, possessing immense power that instilled fear in people.

Even a casual burst of sharp energy caused the golden-armored guard beside him to twitch his eyelids and feel a jolt in his heart.

"This is the magic weapon that suppresses the foundation of my Cloud Heaven Palace. It is a treasure left behind by the founding ancestor and is called the Qinggang Sword. It is extremely sharp and incomparably powerful. Once, a foolish Immortal Emperor at the fifth level came here to kill me. As a result, I used this sword to kill him with one strike, leaving no trace of his body. Although you are an Immortal Emperor at the eleventh level, you will also have to pay a terrible price!"

The Palace Master of Yuntian Palace said with great confidence. She knew the abilities of this immortal sword all too well. Its power was terrifying and could definitely help her defeat enemies of a higher level. Its energy should not be underestimated.

After she finished speaking, she slashed sharply at Gu Changqing with the Qinggang Sword in her hand.

Boom!!!

From within the Qinggang Sword, terrifying auras surged forth like a raging storm, concealing countless surging killing intents. The surrounding space distorted, cracking open with jet-black fissures.

The sword intent continued to advance, its momentum like a shooting star, traversing through layers of void, utterly terrifying.

In the blink of an eye, the sword was about to pierce Gu Changqing.

Gu Changqing didn't even blink, remaining completely calm, and said disdainfully, "I just happened to acquire a precious sword, which is now coming in handy. Let's have a contest to see which sword is more powerful, yours or mine."

After speaking, the newly forged Qingxin Sword appeared in Gu Changqing's hand, exuding a powerful aura and overwhelming force.

Without hesitation, Gu Changqing picked up the Qingxin Sword and slashed at the Qinggang Sword of the Palace Master of Yuntian Palace.

In an instant, a flash of sword light streaked past like a thunderbolt.

"Boom!!!"

The two swords clashed fiercely, sparks flying everywhere like fireflies, and a powerful tornado, comparable to a category 12 typhoon, erupted, sending out a terrifying shockwave.

The surrounding walls were teetering on the brink of collapse, seemingly about to crumble and disintegrate.

With a loud clang, the palace master's sword was cleaved in two, the blade falling directly to the ground, instantly turning the sword into a piece of scrap metal.
