Lu Qing'an put himself in the demon's shoes. If it were him, with enough Glazed Realm corpses, he wouldn't have to make a move. If there weren't enough corpses, he might have launched a surprise attack tonight. However, Xu Qingying didn't feel a strong sense of crisis.

"It seems that the demonic reinforcements this time have most likely brought enough corpses. This means that they will not act rashly and will choose to lie dormant until the demon dragon is sealed and destroyed."

Lu Qingan deduced.

Xu Qingying was surprised and asked, "How could you deduce so much information?"

Lu Qingan replied calmly, "It's not difficult. If you think about it more, you will become more proficient in it."

After roughly figuring out the demon clan's plan, he also re-formulated his strategy.

He cannot let these demons wait until that opportunity, otherwise he might not be able to split himself to kill the dragon. He must take action in advance to eliminate the demons!

"If these demons aren't in the city, they must be outside. But if I go outside to search for them alone, it won't be a good idea. If I use up all my defensive treasures early, I'll be in great danger in the final battle. And if I bring Bai Lu and the others with me, it will reveal that I've already set up a large demon-hunting formation..."

Lu Qing'an was in a dilemma.

But soon, he had an idea.

The three demons in the Prison Immortal Tower!

Why not make use of the three demons in the Prison Immortal Tower?

He could use the three demons as an excuse to first explore the demons' hiding place outside the city. After finding them, he could go back to the city lord's mansion without alerting the enemy and pretend that he had let a demon go and had a way to track it, so he could take a group of people to wipe it out!

With their current strength, the probability of killing all these demons is not high. Some demons must have escaped. Then there is no direct evidence to prove that he did not find the hiding place of the demons by this method.

"If we were more cautious, we could have someone disguised themselves as a demon and escaped over there, and then everything would fall into place!"

Lu Qing'an began to think about who would disguise himself as a demon. If Zhen Yongfu were there, with their years of tacit understanding, it would be a perfect match. However, Zhen Yongfu had already gone to the Immortal Sword Sect, and the only person who could be used at the moment was Xu Qingying.

Xu Qingying looked at Lu Qingan and instantly understood something. She smiled bitterly and said, "What kind of risky thing are you going to ask me to do?"

Lu Qingan smiled and said, "That's not really a risk. Just listen to me and you'll be fine."
