Yang Qi took a few deep breaths to calm himself down.

Once calm, he began to think.

Indeed.

It was June, and the weather was getting hot. Down south, the rains were frequent, which meant it was peak season for mosquitoes to start running rampant.

’As for why the system would name mosquitoes "Bloodthirsty Demon Crows"...’

’It’s a little bizarre, but on second thought, mosquitoes suck blood and spread diseases, so "bloodthirsty" is actually quite fitting.’

’Maybe "Demon Crow" is some kind of codename?’

’Whatever.’ 𝒻𝑟ℯℯ𝑤𝑒𝑏𝑛𝘰𝓋𝑒𝓁.𝒸𝑜𝘮

’The important thing is that killing one mosquito earns 1 contribution point!’

’This is practically a windfall from heaven...’

’No, it’s a contribution point windfall!’

The next crucial step was figuring out how to kill mosquitoes efficiently and in large numbers.

Waving an electric fly swatter around was too inefficient. Besides, it was too conspicuous and would attract unwanted attention.

Yang Qi had no desire to look like an idiot.

He had to find a way to exterminate mosquitoes on a massive scale within the confines of his residence by the mountain.

Thinking of this, Yang Qi immediately took out his phone and searched for keywords like "efficient mosquito extermination methods," "commercial mosquito traps," and "types of mosquito attractants."

After some research, he had a plan.

After dinner, he immediately drove to a large supermarket in the city, heading straight for the home and outdoor goods section.

First, he bought several commercial-grade, high-efficiency bug zappers, which boasted wide coverage and dense electric grids.

Next were a few multi-band, high-power mosquito lamps, which used specific UV wavelengths to attract mosquitoes.

He also grabbed several high-powered electric swatters, the kind advertised with slogans like "One swat is all it takes to get rid of them all."

In addition, he bought a large quantity of dry ice, which would release carbon dioxide to mimic human breath and attract mosquitoes.

He also purchased several types of compound chemical attractants capable of simulating the smells of human sweat, lactic acid, and more.

Yang Qi bought a huge pile of each item, nearly clearing the shelves and earning frequent sideways glances from the sales staff.

Returning to his residence by the mountain, Yang Qi began to set up.

In the backyard, facing the mountain forest where the mosquitoes were most likely to attack from, he strategically placed the commercial bug zappers and multi-band lamps, plugging them all in.

A faint purple glow lit up the night, accompanied by a soft electrical hum.

Next, he mixed the dry ice with the compound attractants and placed the mixtures at several key points near the edge of the vegetation at the foot of the mountain.

Soon, the spots began to emit a faint odor—barely noticeable to humans but incredibly alluring to mosquitoes—accompanied by the low-temperature carbon dioxide gas produced by the sublimating dry ice.

Finally, he disassembled the high-powered electric swatters, removed their grid sections, and modified them with insulated wires and wooden sticks. He connected them to form several small, low-lying "electric grid arrays," securing them along the inevitable flight paths of mosquitoes coming from the forest into the backyard, and plugged those in as well.

This combination of physical light attraction, chemical bait, and electric grid extermination formed a three-pronged, multi-layered "Demon Extermination Array" targeting the mosquitoes.

With everything in place, Yang Qi went back inside. He even set aside his daily cultivation routine for the moment. Sitting by the window, sipping water, he waited with great interest for the "harvest."

Soon—

[Congratulations, Host. You have killed one "Bloodthirsty Demon Crow." Contribution Points +1]

[Congratulations, Host. You have killed one "Bloodthirsty Demon Crow." Contribution Points +1]

[Congratulations, Host...]

...

The system prompts began to appear at a steady, constant rate.

’It’s only 1 contribution point per kill, but the sheer quantity and frequency make up for it!’

Faint ZAP sounds occasionally came from the direction of the bug zappers—the sound of mosquitoes being hit by the electric grids.

A faint burnt smell hung in the backyard air as one mosquito after another was electrocuted.

An hour later, Yang Qi did a rough estimate. His "Demon Extermination Array" had taken out more than two hundred mosquitoes!

Over two hundred contribution points.

’This speed, this efficiency... it’s so much better than the hard work of feeding and cleaning the animals every day!’

Yang Qi couldn’t help but chuckle inwardly. A grin spread across his face, and he reached out to pet the furry heads of Xiaojiu and Ta Xue, who were lying beside him, before bursting into laughter.

"Meow?" Xiaojiu lifted its head and looked at Yang Qi, its eyes full of confusion.

What’s wrong with him?

"Meow meow?" Ta Xue also tilted its head, looking at Yang Qi with puzzlement.

What’s he so happy about?

"Woof~"

Though Bai Wan didn’t know what was going on, it grinned when it saw Yang Qi laughing, its tongue lolling out and its tail wagging happily as it joined in on the fun.

"Haha, it’s nothing, it’s nothing. I’m just happy!"

Yang Qi vigorously ruffled the heads of his little furballs, feeling utterly delighted.

Watching the contribution points steadily climb, his fingers started to itch.

’Time for the lottery!’

[Congratulations, Host. You have won a prize: Qi Condensing Pill (Low-grade)]

’Not bad.’

Yang Qi nodded slightly.

He had already used up the Qi Condensing Pills he’d won before for his cultivation, so this was a welcome restock.

’Again!’

[Congratulations, Host. You have won a prize: Low-grade Spirit Stone (Wood Attribute)]

’Another Spirit Stone!’

’And it’s Wood Attribute.’

’After the Fire Spirit Stone before, now a Wood Spirit Stone?’

Lost in thought, Yang Qi temporarily put away the Spirit Stone, which glowed with a faint bluish-green light and felt warm and smooth to the touch.

Mosquitoes are most active right after nightfall and in the early morning.

So, the next day, Yang Qi got up at the crack of dawn and went to the backyard to check.

Sure enough, the bug zappers and electric grid arrays were filled with many more mosquito corpses.

Combining that with the system prompts, a rough count revealed that, including last night’s haul, the total number exceeded eight hundred!

’Over eight hundred contribution points. I’ve struck it rich overnight.’

Excited, Yang Qi began the lottery draws.

[Congratulations, Host. You have won a prize: Strengthening Pill]

’Alright, a standard supply item.’

’Keep going!’

[Congratulations, Host. You have won a prize: Low-Grade Spirit Rice (five pounds)]

Not bad. He, along with Xiaojiu, Ta Xue, and Bai Wan, had Spirit Rice Porridge every evening.

Spirit Rice had already become their main staple.

’Again!’

[Congratulations, Host. You have won a prize: Low-Grade Spirit Tea (half a pound)]

’Spirit Tea?’

Yang Qi’s eyes immediately lit up.

’This is great stuff!’

He checked the system description. Long-term consumption of Spirit Tea could slightly increase one’s Spiritual Power and slowly strengthen their Spiritual Sense.

This would be a great benefit for cultivating the Great Derivation Spirit-Controlling Technique, a Cultivation Technique that required fine control over Magical Power and Spiritual Sense.

Satisfied, Yang Qi put it away.

’Keep going!’

[Congratulations, Host. You have won a prize: Strengthening Pill]

’Alright, a standard item. I can give it to the little ones as a supplement now and then.’

’Again!’

[Congratulations, Host. You have won a prize: Low-grade Spirit Stone (Gold Attribute)]

’A Gold Spirit Stone?’

’After the Fire Spirit Stone and the Wood Spirit Stone, now I’ve gotten a Gold Spirit Stone.’

’I’ve got three of the five elements now!’

Yang Qi’s eyes narrowed.

’Last draw!’

[Congratulations, Host. You have won a prize: Stone Jade]

’Stone Jade?’

Curious, Yang Qi checked the description.

[Stone Jade]: An Earth Element Spiritual Object nurtured by heaven and earth, containing pure Earth Attribute Spiritual Power. After refining and absorbing it, one can slightly improve their Earth Attribute Spiritual Root aptitude and strengthen their physical foundation.

’It can improve Spiritual Root aptitude!’

’Earth Attribute!’

’It’s basically confirmed now. My Spiritual Root aptitude includes all five elements.’

The Water Attribute Three-tailed Spirit Fish, the Fire Attribute Fire Qilin Fruit, the Wood Attribute Thousand-Year-Old Willow Wood Heart, and the Earth Attribute Stone Jade.

’The only one missing is the Gold Attribute!’
