By this time, the sky had gradually darkened, and the dappled sunlight that had been filtering through the gaps in the tree canopy had completely disappeared.

As night fell, the temperature in the forest began to drop sharply, and a cold atmosphere permeated the air, making one feel as if they were in a giant ice cave.

From time to time, hissing sounds could be heard from the forests on both sides of the road. The sounds were like the howling of evil spirits, which were terrifying.

A thin layer of bluish mist was slowly rising from the road surface illuminated by car headlights.

Ye Li asked Jianjian to make dinner, while he continued browsing the chat channels on his screen.

Compared to watching "The Temptation of Zhen Huan," Ye Li found watching the silly online chats of the survivors more enjoyable.

"Everyone, does anyone else feel that something's not right?"

"I...I feel like ants are crawling all over my body, it's so uncomfortable!"

"Me too, me too. I suddenly felt weak all over and couldn't muster any strength."

"Is it poisoning?"

"Impossible! I've always been afraid of being attacked by poisonous insects and snakes, so I've always kept the car tightly closed. Except for opening the window to throw out the chamber pot after using the toilet, I've never gone out!"

"Could some invisible poisonous insect have flown in?"

"Invisibility? What's the point of playing then? We might as well just die!"

"It shouldn't be. I don't know if you've noticed the mist that started rising from the ground just now. It might be poisonous miasma. In fact, many primeval forests have this kind of thing. If ordinary people are not careful, inhaling too much can easily lead to death."

"You really know a lot!"

"Oh no, oh no, what should we do?"

"Yes, we can stay inside, but we can't stop breathing, can we?"

"Damn it, this place was supposed to be a blessed land! Where's the blessing?"

"Brother, it's just a name, and you actually believed it? From the beginning until now, every path has been littered with corpses."

"We're doomed! We're doomed!"

"......"

Panic began to spread in the chat channel.

Even Ye Li's expression turned serious, and he couldn't help but turn his head to look out of the car.

Under the light, a thin mist could indeed be seen spreading.

Furthermore, the fog seems to be getting thicker.

"But why am I alright?"

Ye Li withdrew his gaze and curiously examined his own body.

There was no discomfort whatsoever.

Am I just too healthy?

Ye Li thought to himself.

However, out of the corner of my eye, I inadvertently caught sight of the potted green ivy on the table.

"By the way, this pothos plant has the effect of purifying the air!"

Ye Li muttered to himself, then immediately picked up the screen, opened the trading marketplace, and began searching for relevant products.

As the page refreshes, a series of air purification-related products appear before your eyes:

【Premium Green Ivy】Price: 5 rare quality materials.

【Premium Daffodil】Price: 6 rare quality materials.

【Premium Potted Sycamore】Price: 6 portions of rare quality materials.

[...]

[Perfect-grade fresh air system blueprint] Price: 100 rare quality materials.

Ye Li quickly glanced around.

I bought 8 pots of pothos, 4 pots of daffodils, and 4 pots of succulents.

In addition, we purchased three more sets of blueprints for the manufacture of fresh air systems.

It's not that Ye Li didn't want to buy more.

However, when Ye Li tried to continue picking up the leftovers, the other survivors seemed to realize what was happening.

Either take it off the shelves immediately, or go on a shopping spree at the same time as him.

Being able to snag these is already considered extremely lucky.

After all, there are still more than 200,000 people in the entire region.

However, less than one-tenth of these air-purifying devices exist.
