When Gu Changqing heard that they were willing to tell him what had happened, he thought it was a good thing, so he stopped and let out a long sigh.

Originally, he planned to keep the two of them alive until they died, but now he changed his mind. Since they chose to reveal some things, it would be entirely beneficial to the Qingyun Sect, and there was no reason not to agree.

As soon as Gu Changqing removed his hands from the two of them, they immediately felt an unprecedented sense of relief. Their fear gradually disappeared, and their bodies instantly returned to their original state. The reason their bodies were able to return to normal was twofold: firstly, that part of their cultivation had not been absorbed by their bodies, and secondly, Gu Changqing had stopped in time.

Otherwise, the two of them would definitely have followed in the footsteps of that Mr. Fang, exploding and dying in a bloody mist, with an extremely tragic end.

"You speak first. Tell me everything you know, and I might spare your lives," Gu Changqing said calmly, pointing at one of the men.

"Chief Gu, actually, we two have only been infiltrating Qingyun for a short time, and haven't sent a single message back to your sect yet, so of course we haven't caused any impact on your sect." One of them said cautiously, his voice filled with fear.

"What nonsense are you spouting? It's no different from saying nothing at all. Is this all I need to know? If I don't show my power, you won't know how formidable I am, will you? If you want to die, I can grant your wish right now." Gu Changqing sneered, his eyes icy, and said without any politeness.

Although they were both Great Emperors, in Gu Changqing's eyes they were still insignificant ants. He could easily crush them with a single finger, turning them into a bloody mist without leaving a trace.

After saying this, Gu Changqing's aura suddenly changed, and the pressure of the fifteenth level of the Immortal Emperor spread out. The void burst open, and an extremely terrifying aura, like the explosion of the universe, suddenly surged out and erupted!

"boom!"

The two were extremely uncomfortable under the pressure of Gu Changqing's aura. Their bodies went limp under the terrifying pressure, and they couldn't get up from the ground for a long time.

Instantly, layers of the void exploded, causing the sky and earth to turn upside down, and the seas to churn and rivers to overflow. The terrifying aura could be felt from hundreds of millions of miles away, making it hard for people to breathe. Those with lower cultivation levels were even almost crushed to the point of losing their souls. It was too frightening.

My God, which big shot has been enraged and unleashed their power? It's absolutely terrifying.

Holy crap, who has such power? This pressure is terrifying.

"Senior Gu, please don't be angry. What we said is true. We are just the lowest-ranking people under the six major demonic sects. We really can't grasp the core and important secrets." The man said tremblingly, as if standing on the edge of an abyss, extremely nervous.

“Yes, Senior Gu, we are just insignificant nobodys. We really don’t know the core secrets you want. The people of the Demonic Sect won’t tell us important things. We don’t know much, but as long as Chief Gu asks, we will tell you everything in detail.” Another man said cautiously, his heart filled with fear.

"Forget it, talking to you is too much of a waste of energy. I'll ask you myself: When will the Sixth Great Demonic Sect attack the Azure Cloud Sect?" Gu Changqing asked directly, without any hesitation.

"There's no specific timeframe, but I've heard it'll be soon. Once I've finished things over there, I'll call here. I estimate it won't be long," the man quickly replied, afraid that Chief Gu might feel slighted and kill him in revenge.

"Alright, secondly, what secrets have you two come to my Qingyun Sect to investigate? Tell me the truth." Gu Changqing smiled coldly and then asked.

"As the chief said, our main purpose was to investigate how many people the Qingyun Sect has and what their strength is, so that we can prepare in advance for attacking the Qingyun Sect in the future." A man said cautiously and fearfully, as if walking on thin ice, afraid of making any mistakes.

"Third, how long have you been infiltrating the Qingyun Sect? What information have you gathered? Have you informed the Demon Sect?" Gu Changqing nodded in satisfaction and continued.

"Senior Gu, we both arrived at the same time, and it's only been a few days. We just found out how many people are in the sect and what their cultivation levels are. We haven't had time to reply to the Demon Sect yet, because if we send back this little bit of information, the Demon Sect will blame us for being useless and incompetent." The two of them told the story in detail.

They dared not lie, for they had just witnessed what terror truly meant; Chief Gu could wipe them out with a single thought, leaving not even a trace.

"Then let me ask you again, did you have anyone to meet you when you infiltrated my Qingyun Sect? Have other sects planted your Demonic Sect's lackeys?"

Gu Changqing's expression remained calm and composed as he asked the question.

A man said cautiously, "There were no inside agents, but other sects did indeed have people from the Demonic Sect planted there. If nothing unexpected happens, they all successfully infiltrated."

As Gu Changqing had predicted, the people from the six major demonic sects had been placed in various sects.

"Finally, I have one more question: how did you manage to do it so secretly and without anyone noticing?" Gu Changqing asked with some doubt.

Considering there are so many people in the sect, it's impossible for him to know everyone. If it weren't for the transmission of his skills, he wouldn't have had the chance to detect the demonic aura on them, and thus wouldn't have been able to identify these two spies.

“That’s easy. We have pills that can help us hide our demonic aura and transform into other people’s appearances. We can kill them and then impersonate them. However, the pills are only effective for seven days. After seven days, they will expire. Neither of us took these pills because the newcomers we were impersonating had already been killed by us before they even entered the Qingyun Sect,” one of them said slowly and without reservation.

"Oh, so that's how it is. Your Demonic Sect is indeed very careful and cautious in its actions, practically foolproof. It's just a pity that the devil is one foot tall, but the righteous are ten feet tall, and I, Gu, still managed to discover it. This is the will of Heaven that cannot be defied!" Gu Changqing said with a slight smile, gloating.

"Yes, yes, yes, Senior Gu is right. Senior Gu is truly amazing. He could spot us as spies at a glance. His eyesight is incredible. We admire him greatly. We wonder if Senior Gu could spare our lives, considering how honest we were. We are willing to abandon our evil ways and serve you faithfully!"

The two quickly and obediently expressed their inner thoughts, begging for a way to survive.
