After traveling through the book, I conquered the male protagonist Long Aotian!

A day later, Gu Qingze, Chu Lingxiao and others arrived at Nebula City.

As the junction between Nebula City and the demon world, naturally not only humans enter the demon world, but also many demon beasts come here from the demon world.

So, looking at the endless stream of monsters and humans on the streets, the two of them felt an unprecedented sense of novelty.

"Let's go buy some props first."

Gu Qingze coughed lightly and reminded.

"okay."

The two walked into a grocery store.

The shop was filled with all kinds of strange and bizarre items, including crystals that flickered with faint light, scrolls engraved with mysterious runes, and herbs that exuded strange aromas.

Chu Lingxiao asked politely: "Boss, do you have any props for disguise here?"

The shop owner was an elderly man. He looked at them for a few seconds and said slowly, "Are you going to the demon world?"

"Yeah, so what does the boss recommend?"

Chu Lingxiao had nothing to hide. There were not many indigenous people in Xingyun City, and most of the people who came here were going to the demon world.

The old man smiled slightly, turned around, took a small box from the shelf and handed it to Chu Lingxiao.

"This is a Hidden Breath Pill. It can conceal your aura and prevent the demons from detecting your human identity."

Chu Lingxiao opened the box, and inside lay two black pills. "Thank you, boss."

"Boss, is there anything here that can simulate the smell of monsters?"

Gu Qingze on the side asked seriously. After all, each species of monsters generally has a special smell. Although the invisibility pill can cover up their unique human breath, it is still too obvious, isn't it?

The old man looked at him and said, "Yes, there are, but that is a different price. The props for simulating monsters are usually very expensive, and ordinary cultivators can't afford them. As long as you don't do anything earth-shattering in the monster world, taking the Invisibility Pill will be enough."

Gu Qingze knew that this was a kind reminder from his boss.

If the boss was a profiteer, he could have just taken out the most expensive item and used verbal attacks to create panic among people, forcing them to buy.... But he didn't...

"Thank you, boss, but we still want peace of mind, so it's safer to have a disguise."

Seeing Gu Qingze's insistence, the old man stopped persuading him and stood up and picked up a large dusty box from the shelf.

There are only a few reasons why humans go to the demon world: either they have half-demon blood and go to visit relatives; or they go to the demon world to make some money by reselling some materials unique to the demon world; or they are not afraid of death and go there to satisfy their curiosity...

After all, there are not many people who are particularly rich, so not many people buy such expensive things, and over time, they just get covered in dust.

"Boss, it looks like it's been a long time, maybe it's expired."

Gu Qingze asked uncertainly. Although he didn't know whether there was such a thing as expiration in the world of immortal cultivation, he had heard of the loss of medicinal efficacy.

"How could I possibly sell defective goods like you, kid?"

The old man blew away the dust on the big box, and was immediately choked by the flying dust in the air and started coughing.

"Cough, cough, cough, I'm choking to death. I've opened a shop here for more than 40 years, and I've always run it with integrity. Don't you think I'm just a small cultivator in the Foundation Establishment Stage? If I dared to sell fake goods, I would have been hacked to death long ago. How can I still sit here?"
