After walking slowly for about ten minutes, the stench became stronger and stronger, but the wind also noticed the change in the color of the soil under his feet.

The further you go, the more the dirt tends to turn yellow!

Seeing this, Feng Xi probably guessed something, but soon, she confirmed it with her own eyes.

Feng Xi's footsteps stopped, looking at a yellow mountain wall in front of him, and the corpses of demonic beasts around him.

I couldn't help but frown.

It turned out to be really sulfur!

No wonder there is no trace of the monster nearby.

However, this area turned out to be a sulphur field, so why is it so lush with trees?

Feng Xi really couldn't figure it out, however, at this time, a voice sounded in his head.

"Girl, there is an entrance to a cave in the grass next to the mountain wall, go inside."

"Go in?" Although the toxicity of sulfur is not very strong before heating and oxidation, it is still harmful to the human body.

And the corpses of the demonic beasts around this place can illustrate a point, some of this sulfur must have been oxidized by high temperatures, so it will emit strong toxins and poison those demonic beasts to death.

"Rest assured, this loess poison will not cause the slightest harm to your body." As if to understand Feng Xi's concerns, the voice sounded in his head again.

Hearing this, Feng Xi didn't hesitate in the end!

Anyway, if this sulfur poison can bring her down, then she doesn't have to mess around in this other world.

The entrance to the cave was very small, and if it weren't for the fact that she was now as thin as a six or seven-year-old girl, she would probably have to be squeezed.

As soon as I entered the small cave, the smell of sulfur, which had been strong outside, was actually cut off, and there was a faint smell of flowers in the air.

The cave is not deep, and through the low entrance, it is only a space of about ten square meters.

However, it is quite strange that in this sulfur cave, there are many black grasses in the shape of rice grass, and the faint fragrance of flowers is emanating from these grasses.

"Little girl, be careful, don't touch those black vampire grass on the wall, this grass exudes a fragrance, and whether it is a person or a demonic beast, as long as you smell this fragrance, you will be lured uncontrollably and suck the blood, you have a special physique, you will not be tempted, but you will also be sucked dry if you are knocked down."

Sucked dry?

Hearing this, Feng Xi's cold eyes couldn't help but have a touch of shame.

So what did he let her in? Could it be that in order to make her see that this grass is called vampire?

However, at this moment, suddenly a foul smell filled the air, and then a 'hissing' sound came from behind him.

This......

Feng Xi turned her head and saw that she had been honed by her twenty-nine years of experience as a killer, and she was almost scared to the point that her feet were weak.

I saw a snake head as tall as her own, slowly sliding in through the entrance of the cave she had just entered.

And the three-pronged tongue, which was as thick as her thighs, was hissing and spitting, with two sharp fangs long and exposed, and a pair of eerie green eyes like lanterns.

It's really making people get goosebumps in an instant, although she is a killer, this concentration is better than others, but she still can't bear it when she sees such a person in front of her.

So I couldn't help but take a few steps back!

However, at this moment, Feng Xi saw a strange and thorny scene, which made her face pale for a moment, and her heart trembled so much that she almost couldn't help but want to scream......
