The longevity killing formation on the eighth floor could slay Human Immortals, which meant the formation on the eighth floor was definitely not simple.
Just now, what Ye Kunlun saw was merely an illusion of Nangong Yunshao, but Ye Kunlun did not seem to realize this.
This gave Gu Changsheng a bit more confidence in slaying Ye Kunlun. If Ye Kunlun were trapped by illusions, killing him would not be difficult.
After Ye Kunlun's sword strike, Nangong Yunshao appeared behind him, her gaze complicated, and she said faintly, "I told you, I cannot die yet, and you cannot kill me!"
Ye Kunlun wasted no words and turned to strike her with his sword.
Nangong Yunshao disappeared again.
This repeated seven times, and Ye Kunlun seemed to be trapped in illusions, fixated on killing Nangong Yunshao.
Gu Changsheng's eyes revealed murderous intent, "Ye Kunlun, today I shall slay you here!"
When Nangong Yunshao reappeared, Ye Kunlun thrust his sword at her.
At the same time, a saber and a sword, coming from the void, struck Ye Kunlun's back and dantian.
The speed was so great that even if Ye Kunlun wanted to dodge, he might not have enough time!
In an instant, Ye Kunlun was struck by the saber and the sword!
"Haha!"
Gu Changsheng's laughter echoed from the eighth floor of Qintian Tower, "Ye Kunlun, although you broke through the formations of the first seven floors, you can only die on the eighth floor!"
In Gu Changsheng's view, that sword had pierced Ye Kunlun's heart, and that saber had cleaved his dantian.
Even if Ye Kunlun were an immortal, he would surely die.
"Hehe, is that so?"
Ye Kunlun's laughter came from all directions, "Gu Changsheng, since this eighth floor is an illusion formation, can you see that the eight sword strikes I just made were also an illusion formation?"
As he spoke, Ye Kunlun, who had been struck by the sword and saber, vanished!
He stepped onto the stairs, appearing at the doorway of the ninth floor, looking down with cold eyes at Gu Changsheng, who was sitting cross-legged with a pale face.
"I was just playing with you. A mere longevity killing formation, and you can't even activate the formation on the ninth floor, yet you want to kill me? You think too highly of Qintian Tower!"
Ye Kunlun's voice was like a sharp sword piercing Gu Changsheng's heart.
"No, impossible. The illusion formation on the eighth floor is a heart formation. How could you have walked out so easily?"
Gu Changsheng looked at Ye Kunlun, who had appeared on the ninth floor, with disbelief.
The reason why the eighth floor could slay Human Immortals was that its killing formation was a heart formation, which could immerse people in their own inner world and slay them invisibly.
Heart formations were extremely profound, and there were only a handful of people in the world who could set them up.
The heart formation on the eighth floor of Qintian Tower could even slay Human Immortals!
Yet Ye Kunlun walked from the eighth floor to the ninth floor as if the heart formation was nothing to him!
"Gu Changsheng, do you know who built this Qintian Tower?"
Ye Kunlun looked at Gu Changsheng, whose face was filled with shock, and asked indifferently.
Gu Changsheng tried to calm himself, "Of course. The first楼主 of Qintian Tower was the Imperial Tutor!"
This was also one of the reasons for Qintian Tower's transcendent status.
Everyone in the capital knew that the first楼主 of Qintian Tower was the master of the Saint of the Shanhe Terrace at that time.
And Qintian Tower was built under the supervision of the first楼主, with the purpose of consolidating the capital's destiny.
"Then do you know who the Imperial Tutor is to me?" Ye Kunlun continued to ask.
Gu Changsheng was startled and instinctively asked, "Who is the Imperial Tutor to you?"
"He is my master!" Ye Kunlun replied indifferently.
Hearing Ye Kunlun's answer, Gu Changsheng was dumbfounded!
Looking at Gu Changsheng's dumbfounded face, Ye Kunlun gazed at him and asked in a cold voice, "Gu Changsheng, as the楼主 of Qintian Tower, you should serve the country and the people. Yet you colluded with the Wu clan and the Eastern Japanese, and you do not realize your crime?"
Gu Changsheng, having recovered from his shock, gave Ye Kunlun a mocking look, "Ye Kunlun, do you take me for a three-year-old child?"
"The first楼主 of Qintian Tower passed away long ago. This lie about you being his disciple can only fool a three-year-old!"
Gu Changsheng was almost fooled by Ye Kunlun.
A disciple of the first楼主 could indeed bluff him.
But after he came to his senses, he felt it was simply impossible!
The first楼主 had already passed away more than a hundred years ago. According to the records of Qintian Tower, the first楼主 was already sixty years old back then!
Wouldn't he be nearly two hundred years old if he were alive now?
Was that possible?
Even though he knew that some families in the capital had managed to keep a few old monsters alive through secret arts, they were not two hundred years old.
"Hehe."
Ye Kunlun chuckled, "Your Longevity Art comes from the first楼主, but it's a damaged version. This is the true Longevity Art!"
As he spoke, Ye Kunlun's spiritual energy circulated within his body according to the path of the Longevity Art.
Instantly, Gu Changsheng sensed the aura of the Longevity Art emanating from Ye Kunlun.
"This, how is this possible?"
Gu Changsheng's face was filled with horror, and he could clearly sense that the aura of Ye Kunlun's Longevity Art was even purer than his own!
"Still don't believe me?"
Ye Kunlun sneered, and shouted, "You just activated the longevity killing formation using the imperial decree, and you couldn't unleash even half of its power. Let me show you what the true longevity killing formation is!"
"Open for me!"
Ye Kunlun shouted coldly, without him using any imperial decree.
Instantly, Qintian Tower trembled. The Taiji diagram on its roof transformed into two Taiji fish, swimming rapidly.
Immediately after, a killing intent that made Gu Changsheng's heart palpitate came from all directions.
Visible spiritual energy rapidly converged towards the ninth floor, forming myriad killing intents.
That was the purest killing intent, so pure that anyone with a low cultivation level would be obliterated by it if they got close!
And Gu Changsheng, standing at the center of the ninth floor, clearly felt that killing intent that made his soul tremble!
It was as if he were in a land of profound ice, with only killing intent surrounding him. That killing intent, which made his soul tremble, was like a Dao.
That's right, it was a Dao of Killing Intent.
Poof—
Gu Changsheng's soul could no longer withstand that terrifying killing intent, and he spat out a mouthful of essence blood, his aura instantly weakening.
"If I wanted to kill you, the Dao of Killing Intent here could obliterate you in an instant. Even someone called a Human Immortal, a Core Formation stage cultivator, would be obliterated in the blink of an eye!"
Ye Kunlun looked at Gu Changsheng with cold eyes and said indifferently.
At this moment, Qintian Tower was no longer under Gu Changsheng's control; it was completely controlled by Ye Kunlun.
Gu Changsheng's face showed horror and fear. Ye Kunlun's methods were enough to prove that he was indeed a disciple of the first楼主.
"Confess everything you know, and I can spare your life!"
Ye Kunlun looked at Gu Changsheng indifferently.
"It's useless!"
Gu Changsheng looked at Ye Kunlun, his gaze complicated.
He rolled up his sleeve, and a soul contract was clearly visible on his arm, just like Zhou Lie's back then.
"Ten years ago, when I made that decision, I already had no retreat!"
Gu Changsheng's tone became calm.
