Chapter 7 Sweeping Away the Mosquito Swarm

"Hit!"

"The mosquito fell!"

Xu Qingling couldn't help but gasp as she watched the mosquito fall.

"11 launches, 3 hits, 27% success rate..."

Lin Dong opened the data in the laser device's backend, a hint of satisfaction in his eyes.

Because mosquitoes are constantly flying and moving, and the laser's identification and locking, as well as the turret's operation and aiming, all require time.

Often, by the time the laser completes its lock-on and launch, the mosquito has already moved from its original position.

A 27% hit rate exceeded his initial expectations.

After all, a laser can fire many times, while a mosquito only needs to make one mistake; the two are simply not on the same level.

The hit rate will improve again once more by collecting more data, improving the performance of the laser, and adjusting the recognition and control algorithm based on the mosquito's trajectory.

According to Lin Dong's estimate, it wouldn't be a problem to eventually increase the hit rate to 50% or even 60%.

As for more than 60%, this is beyond the capabilities of civilian instruments and equipment from 2008; it requires replacing them with military equipment that has lower latency and more sensitive response.

"The last item..."

Lin Dong closed the background data, picked up another bottle containing seven or eight mosquitoes, removed the lid, and released them.

呲——

The laser identifies and captures an image of a mosquito, and the turret immediately begins operation.

But at that moment, Lin Dong suddenly reached out and blocked the laser.

click!

The running drive motor stopped immediately, and the laser's power was also cut off by the control board.

"good."

Lin Dong nodded.

He knew this was an infrared signal being detected from the arm, and to avoid accidental injury, the laser immediately activated the highest priority interrupt procedure.

The function of interrupting infrared signals has been confirmed.

Lin Dong removed his arm to turn off the infrared sensor, and the stopped laser continued to run, hitting and killing three unlucky mosquitoes in less than a second.

But at that moment, Lin Dong put on a pair of glasses cut from thick cardboard, took a step, and half of his body entered the laser's recognition range.

click!

The recognition program detected human-shaped features within its range, and the laser, which was still firing wildly, was interrupted once again.

Human image recognition and infrared signal recognition both passed the tests...

This laser device is extremely safe!

In the living room.

As the parents listened to their children's cheers in the study, Zhou Xiaoyan picked up her teacup, took a small sip, and looked up at Lin Weiliang and Zhang Xiali.

"Brother Lin, Sister Xiali, how did you raise Xiao Dong? Please pass on some martial arts secrets to him."

"this……"

Lin Weiliang and Zhang Xiali exchanged a glance: "We don't know either, the children learned it all on their own."

"She learned on her own... All Qingling has learned is how to play games."

Zhou Xiaoyan complained softly, then changed the subject and said, "Brother Lin, what kind of training plan do you have for Xiao Dong? My husband, Lao Xu, knows a few teachers from the University of Science and Technology of China's Junior Class."

If Brother Lin or your family are interested in sending Xiao Dong to the gifted youth program, we can help with the introductions.

"I have no idea about the gifted youth program."

Lin Weiliang put down his teacup and said calmly, "The child is still young. For now, let him learn and play according to what he likes and is interested in. We can talk about other things when he is older and more stable."

"right."

Zhang Xiali continued, "The child is not even six years old yet, and nothing is set in stone. Cultivating talent is important, but a complete life experience and physical and mental health are equally important."

They discovered Lin Dong's situation yesterday, and the couple had already discussed and reached a consensus last night.

That means letting Lin Dong do what he wants according to his own interests, and all they need to do is ensure his safety and increase resources.

As for other things like math olympiad training or special programs for gifted children, we won't consider them in the short term.

Although every parent hopes their child will become successful.

But before hoping their son will become a dragon, they hope Lin Dong can grow up healthily, rather than becoming a real-life example of a prodigy who failed to live up to his potential or a child who was forced to grow too fast.

"Mr. Lin, your thinking is correct."

Xu Ziming then chimed in, "Cultivating a child's talent is important, but a child's life and mental well-being are equally important."

The success of programs like the gifted youth program and other talent enhancement programs remains unclear, with debate over whether they have been more beneficial or detrimental.

While some gifted students in the gifted youth program have achieved greater success, a significant number of them have developed psychological problems early on, wasting their lives and impacting their overall development.

A child's life should not be a bargaining chip for a parent's vanity.

I have a conservative opinion on these gifted youth programs unless the child is genuinely interested in participating.

"Yes, that's it."

Lin Weiliang smiled and nodded: "So we've decided to prioritize the child's interests and ideas and not interfere too much."

"You guys have such a great attitude."

Upon hearing this, Zhou Xiaoyan couldn't help but sigh, "If I had such a gifted child at home, I would probably have already started thinking about how to nurture him, whether to send him to a special program for gifted children, or to train him to study a particular major in advance."

"Sister Zhou, times have changed."

Zhang Xiali said softly, "These days, kids are all so precocious. They have their own ideas and pace at such a young age. As parents, we can only assist them, not decide their lives..."

Sigrún has taught at the Iceland University of the Arts as a part-time lecturer since and was Dean of the Department of Fine Art from -. In – she held a research position at Reykjavík Art Museum focusing on the role of women in Icelandic art. She studied fine art at the Icelandic College of Arts and Crafts and at Pratt Institute, New York, and holds BA and MA degrees in art history and philosophy from the University of Iceland. Sigrún lives and works in Iceland.

At noon, Xu Qingling's family had lunch at Lin Dong's house and stayed there until 3 p.m. when Gao Chi left.

"Lin Dong, I'm going to my grandma's house tomorrow. See you at school on Monday."

As she was leaving, Xu Qingling was held by Zhou Xiaoyan's hand, her expression full of reluctance as she said goodbye to her friend.

See you Monday.

Lin Dong waved from the doorway, and after Xu Qingling's family had walked away, he turned and went back to the tool area in his study.

Wearing corrosion-resistant and insulating gloves, Lin Dong forcefully moved out three lead-acid batteries, then took a 12V inverter and began soldering his DIY power bank.

Since the laser turret will be used outdoors, the power supply issue must be resolved.

Currently, there are no large single-cell energy storage batteries with a capacity of 2 kWh each, which will be used in the future 628AH batteries. We can only use these heavier and lower-capacity lead-acid batteries for assembly.

Three lead-acid batteries are connected in series to boost the voltage to 6V, and then the inverter boosts it to a stable 12V, which is directly connected to the power module. This allows the system to switch between multiple 12V, 5V, and 3V power supplies to the control board and laser.

At six o'clock in the evening, Lin Dong assembled and charged the power bank, left the study, and searched the house, but could not find his father, Lin Weiliang.

"Mom, where's Dad?"

"My dad had an emergency at work, and he was notified around 4 a.m. to go there."

Zhang Xiali, who was arranging vegetables in the living room, looked up at Lin Dong and asked, "Xiao Dong, is there something you need to talk to your father about?"

"I want to move this laser downstairs to do an experiment, but the power supply is too heavy for me to move," Lin Dong truthfully explained his predicament.

Lead-acid batteries are notoriously heavy.

As a five-year-old child, he can still move a piece of paper slowly.

But now that the three pieces are connected together, this is no longer a task he can take on.

"Then Mom will help you carry it downstairs."

Upon hearing this, Zhang Xiali took the grocery shopping cart and carried the battery pack that Lin Dong had assembled and secured with cable ties onto it, and also put the laser device on it at the same time.

"Mom, put it by the artificial lake near the entrance; there are more mosquitoes there."

After taking the elevator down to the first floor, Lin Dong pointed in the direction of the artificial lake, indicating that Zhang Xiali should go there.

Evening is the time when mosquitoes are most active, and swarms of mosquitoes hover over the grass and water, making it the perfect testing ground for lasers.

Lin Dong sprayed mosquito repellent on the two of them, then led Zhang Xiali to move the battery to a green area next to the artificial lake. He then took a stool and placed the laser cannon next to it and began wiring.

"alright!"

Soon, Lin Dong plugged in the power, the indicator light on the motherboard lit up, and the control program entered the self-test program... The camera started, the infrared probe was calibrated, the horizontal motor returned to zero, and the pitch motor returned to zero.

beep!

Three seconds later, the self-check was completed, and the laser turret began to operate.

The camera captures images and transmits them to the motherboard via a high-speed cable. The graphics card's performance utilization spikes, and the recognition program begins to automatically compare and identify the mosquito tracks in the images.

The next instant, the turret moved.

The horizontal and vertical motors operate simultaneously, causing the laser emitter to trace an arc and lock onto one of the mosquitoes.

呲!

Laser pulse duration 0.1 seconds, interval 0.1 seconds.

Five lasers shot out per second, piercing the twilight. A mosquito flying in the air flashed red light, then froze, falling through the air with a wisp of smoke rising from its body.

When it fell onto the grass, its six legs were still twitching slightly.

However, the abdomen was already charred black and emitted a faint burnt smell.

Sizzle sizzle sizzle—

Before Zhang Xiali could react, the laser began to fire continuously, and the motor kept starting to fine-tune the laser's angle.

A 27 percent hit rate.

On average, a mosquito is hit in less than one second.

The swarm of mosquitoes flying around in the green belt underwent a visible change at this moment.

One by one, the mosquitoes flashed red light, then broke away from their original flight path and began to fall from the sky like rain.

Within minutes, the grass was covered with mosquitoes, and the air was filled with a strong smell of burning.

"this!"

On a bench not far away, Zhang Xia stared wide-eyed at the swarm of mosquitoes falling one after another, unable to believe her eyes.

Although she knew that Lin Dong had been tinkering with the laser device these past two days, she also knew that Lin Dong was preparing to use the laser device to kill mosquitoes.

But no one told her that the laser would be so powerful.

It can accurately hit flying mosquitoes even at a distance of five or six meters.

You should know that people with slightly poor eyesight probably can't even see a mosquito five or six meters away.

"Such a reaction speed, and such a high accuracy rate..."

As Zhang Xiali stared at the flashing red laser, a thought suddenly popped into her mind: "What if military interception were used..."
