When the people from the sect flew out, they were actually teleported out from the Particle Secret Realm. The same principle applied to entering inside. It seemed that they had entered the mountain gate, but in fact they were directly teleported into the Particle Secret Realm through the formation.

Therefore, even if all the demons suddenly came to kill him, he only needed to do one thing, which was to control the particle secret realm formation to quickly close the entrance to the secret realm and escape into the void, then the demons would never find the Xianjian Sect.

And all he needs to do to close the entrance to the secret realm is just a thought.

Lu Qing'an flew into the formation again, and the next moment he could still feel that special slight movement. After entering the particle secret realm, he flew towards the cave where Xu Qingying was.

When he arrived in front of Xu Qingying's cave, Xu Qingying was standing in front of the cave waiting for him again.

"The entrance to the secret realm suddenly disappeared, and there was a slight change in the sect just now. Did you take away the entrance to the secret realm?" Xu Qingying asked.

Lu Qing'an nodded and asked with a smile, "Have you noticed any changes in the Immortal Sword Sect?"

Xu Qingying looked at the sky and shook her head.

"Now, the entire sect is actually already within the Particle Secret Realm."

"Really?" Xu Qingying looked surprised.

"Didn't your intuition tell you that there is no one left in the Immortal Sword Sect who can threaten it now?"

"Indeed, the heart-wrenching feeling that the catastrophe gave me has completely disappeared."

"That means the catastrophe will still come as usual, right?"

"They will still come to kill us at that time."

"A month and a half?"

"About a little over a month."

"Very good. Next, what I have to do is to find a way to make those people pay the biggest price."

If Chen Changsheng is really dead, then the people who killed him are most likely those from the Chaos Sect.

Because when he stole the Chaos Sect's Particle Secret Realm Formation that day, he saw Wu Jin appear next to Sun Lei. And in the entire fairy world, who has the most incredible talent in formation?

The shadow left by Chen Changsheng gave him a key message, which was to be wary of Wu Jin.

Perhaps, Wu Jin reminded Sun Lei that the person who stole the Particle Secret Realm was Chen Changsheng, and coupled with the threat of Chen Changsheng's Demon Hunting Formation, they began to set up a plan to kill Chen Changsheng.

"Brother Chen, I'll borrow your reputation again and meet them."

Lu Qing'an took out the sound transmission jade slip and sent it to Liu Lingxuan: "Uncle-master, spread the word that Chen Changsheng has handed over a thousand Demon Hunting Arrays to us. They will be available for sale in two months."

It depends on how many people the thousand demon-hunting formations can attract in a month!

A hint of ruthlessness flashed in Lu Qing'an's eyes: "I actually hope that all of you who have colluded with the demons will come. Then I will give you a big surprise!"
