The land of smoke miasma seems to be far away, but since Xiao An can run out to play, he must have his own set of shortcuts.

Nie Yunwen followed it, and in less than two hours, she had already reached the border.

The reason why I didn't use my supernatural powers to fly was to avoid being discovered by the beings in the miasma, which would easily cause unnecessary trouble when the time came.

As for whether Xiao An would calculate her, Nie Yunwen didn't care at all.

Would a Jindan stage monk be afraid of an ant in the Qi refining stage?

"Hey, Xiao An." Her eyes froze, and she suddenly stared at the dirt beneath her feet.

"Well, please." Seeing that she seemed to have questions, Xiao An hurriedly stopped.

Nie Yunwen squatted down, reached out and picked up a handful of dirt, and rubbed her fingers lightly: "Why is the soil here purple?" ”

Xiao An scratched his head and was a little puzzled: "I just grew out of this soil, and I don't know what the difference is." ”

Nie Yun glanced at the traceless air in front of her again, and had some guesses: "When I looked at it from a distance, there was a large area of purple smoke miasma here, which was very obvious, but now that I got closer, I couldn't see it?" ”

"Only this land is purpleer than the miasma of the millamen."

Xiao An nodded: "Those purple smoke miasma...... It's pollen. ”

Pollen? Nie Yunwen looked over suspiciously.

Xiao An said: "In this jungle, except for frog trees like my younger brothers and sisters, there are low shrubs and flowers. ”

"The purple mist is the result of the pollen of some flowers and plants distributed in a large area......"

When he said this, his face changed, and he hurriedly said, "Miss Nie, it's better not to go in." ”

"As soon as I remembered, many of the monks who came here were almost all delirious or in poor health, and they simply died inside."

Nie Yunwen nodded secretly when she heard this, she didn't plan to break in directly, if Xiao An really wanted to calculate her, she didn't need to remind her of this, just let her fend for herself after she entered.

"I see." She took out a bottle of elixir from her bosom, and the color of this bottle was different from the others.

The dark brown bottle is not labeled with any name on it, and it seems that this kind of medicine is usually used by Old Man Du himself, and it is a research pill.

"What is this?"

Nie Yunwen didn't shy away from it when she took the medicine out, and Xiao An naturally saw it.

"Fire Shelter Pill. It is a kind of Gongdan. ”

The so-called Gongdan is not used for eating, it is usually some ancillary products during alchemy, and pharmacists will use these "wastes" for other purposes.

For example, this fire avoidance pill, as the name suggests, should prevent fire. Not really.

It is used to filter harmful gases.

Most of the reasons why people die in fires are because the breath is not smooth and a lot of smoke and dust are inhaled.

And this elixir, there is no limit, and mortals can also use it.

If you hold it in your mouth, all the smoke and dust you inhale will be filtered, and all harmful things will accumulate into the fire avoidance.

Nie Yunwen took it out and used it this time, in fact, the main reason was to collect the harmful things in the smoke miasma, and bring them to Master Du for study after they went out.

It can not only help the younger brothers and sisters to detoxify, but also accurately match the correct antidote.

Nie Yunwen looked back and saw Xiao An looking like a curious baby, and she didn't bother to explain to him, but said, "If you like it, I'll give you one when I go back, and I'll explain it to you slowly when the time comes." ”
