I started by watching videos, and I chose 10,000 combat power.

Luo Fei placed the last prepared herbal bath pack aside.

On the table, the scraps of various medicinal herbs and their packaging paper had been cleaned up, and the electronic scale had been put away.

Just then, the cell phone on the corner of the table rang.

Luo Fei picked up his phone and saw that it was Zhou Mingyu calling.

He swiped to answer the call.

"Hello, Director Zhou."

"Xiao Luo, did I disturb you?" Zhou Mingyu's voice came through the receiver.

"No, I just finished what I was doing. Director Zhou, please speak."

"It's about that 'anti-gravity skateboard' thing." Zhou Mingyu didn't waste any time with pleasantries and went straight to the point. "The preliminary research at the Academy of Sciences has begun, but it's encountered enormous difficulties."

He paused slightly, as if considering his words.

"The technical level of skateboarding itself is completely beyond our current understanding. The research team had no clue about many of the basic principles."

"President Chen and several chief scientists from the Academy of Sciences made a... which could be considered a plea."

Zhou Mingyu's tone carried a questioning tone.

"They hope that when it's convenient for you, you could provide some guidance on some key techniques involved in skateboarding, or even just the most basic theoretical aspects?"

"Of course, it all depends on your willingness and time."

His words were tactful, but his meaning was clear.

The Academy of Sciences leadership hopes that Luo Fei can provide more information about skateboarding technology to accelerate the research process.

Luo Fei showed no surprise after hearing this.

He walked to the window and looked out at the lawn in the villa's yard, where his two younger sisters were earnestly teaching their parents and aunt the movements of body-strengthening exercises.

"Director Zhou,"

He spoke calmly.

"I need to explain something about that skateboard."

"It was a finished product that I obtained by chance through special means."

"I understand its basic operating methods and safety precautions, which I have already written in the guide."

"but--"

"I know nothing about its manufacturing principles, core technologies, energy, and all these technical aspects."

There was a few seconds of silence on the other end of the phone.

"I understand." Zhou Mingyu's voice returned to normal, filled with understanding. "Xiao Luo, thank you for your honesty. I will relay your words truthfully."

"Scientific exploration is inherently full of unknowns, and figuring things out on your own is an inevitable path. The physical objects you provided are already priceless."

His attitude was very proper, and he showed no dissatisfaction or doubt because Luo Fei "didn't understand".

"I'm sorry to have troubled you."

"Director Zhou, you're too kind."

Luo Fei replied politely.

"If there's anything else that requires my cooperation, please feel free to contact me."

hang up the phone.

He could imagine the excitement, confusion, and eagerness to find answers that a group of top scientists in Kyoto felt when faced with technology that was ahead of its time.

But there was truly nothing he could do to help.

The system rewards the finished product directly, without providing a complete set of technical information.

He stopped thinking about it.

I checked the time and realized that my parents and aunt would also be taking a medicinal bath after their practice tonight. I had only prepared wooden tubs for my two younger sisters, so I would need to buy three more.

So, he picked up the prepared medicine, turned around and went downstairs without disturbing his family members who were practicing vigorously in the yard. He put the medicine in the kitchen cabinet, then went straight to the garage, drove out, and left.

He went to a large supermarket nearby and bought three solid wood bathtubs, as well as a lot of fresh ingredients, filling the trunk of his D9 to the brim.

When we returned to the villa, it was nearly dusk.

In the living room, my parents and aunt were slumped on the sofa, their faces flushed, their foreheads sweaty, their clothes disheveled, and their breathing heavier than usual.

Luo Ying and Zhao Lin stood to the side, one holding a towel and the other holding a cup of warm water, their faces showing concern.

"Mom and Dad, Aunt, are you alright...?" Luo Fei put the things in the entryway and came over.

"Oh dear, Xiaofei's back." The mother waved weakly, but a smile played on her lips. "He's exhausted. Those two little ones, Yingying and Xiaolin, are so strict..."

The father wiped his sweat and said with a wry smile, "You really can't deny getting old. I just practiced a few seemingly simple movements, and I feel like all the bones in my body are falling apart. It's more tiring than carrying cement on a construction site all day when I was young..."

Luo Yumei didn't complain, but she was panting, "I'm tired, but I feel much more relaxed after practicing. It's just that my arms and legs don't obey me."

Luo Ying immediately sidled up to Luo Fei, as if to claim credit: "Brother! We taught so diligently! Mom, Dad, and Aunt all worked really hard! It's just that the basics are a bit weak; the first movement wasn't quite up to standard yet."

Zhao Lin added in a low voice, "The main problem is insufficient flexibility and strength control..."

"Take it one step at a time, slow and steady. You've done very well on the first day."

Luo Fei affirmed his sisters' work, and then said to his parents and aunt, "It's normal to be tired. It means you've done the movements correctly and your energy has been mobilized. Take a good rest first, and soak in a medicinal bath tonight to relieve your fatigue. You'll feel much better tomorrow."

He checked the time.

"You guys rest for a while, I'll go cook."

After saying that, he picked up the groceries he had bought and went into the kitchen.

Tie on an apron, turn on the tap, wash the vegetables, and prepare the meat.

Soon, a steaming hot and fragrant dinner was ready.

Four dishes and a soup, a feast for the eyes, nose, and palate.

The three people, who had been exhausted and collapsed on the sofa, regained some strength upon smelling the aroma, and stood up to sit around the dining table.

"Wow! Brother, you're amazing! So much delicious food!" Luo Ying cheered.

"Xiao Fei's skills are truly exceptional," Luo Yumei exclaimed.

The meal was exceptionally delicious, especially for Luo Weidong and his two companions who had expended a great deal of energy; they had a hearty appetite.

After dinner, Luo Fei asked his sisters to watch TV with their parents and aunts to rest and digest, while he carried the three newly bought wooden buckets to the tap in the backyard and carefully washed them clean.

The bucket was washed and left to dry.

He went back to the kitchen, took out three earthenware pots, put the medicinal bath packs into each, added water, and began to boil them.

Soon, the aroma of medicine wafted from the kitchen and gradually permeated the living room.

"What's this smell?" Luo Weidong sniffed.

"My brother's brewing the herbs for the medicinal bath," Luo Ying explained. "It'll be used for the bath later, it'll be so relaxing!"

After resting for about half an hour, Luo Fei checked the time and found that the medicine was almost ready.

He turned off the fire and let the medicinal liquid cool down naturally in the clay pot.

"Yingying, Linlin, you can continue practicing with Mom, Dad, and Aunt for a while. Dinner should be mostly digested by now," Luo Fei called out to his sisters in the living room.

"Okay!"

Luo Ying immediately pulled her mother, whose back was still aching, to her feet: "Mom, let's walk, let's practice a few more times to reinforce what we learned today, otherwise we'll forget it tomorrow!"

Zhao Lin also politely asked Luo Weidong and Luo Yumei to get up.

The four of them then went to the lawn in the backyard.

A gentle breeze swept by on a summer night, bringing a touch of coolness.

Under the lights, two young girls were explaining, demonstrating, and correcting in a very professional manner.

The three elders tried their best to imitate, and although their movements were still awkward and stiff, and their foreheads were soon covered in sweat again, they were all very serious and none of them called for a stop or gave up.

Seeing this scene, Luo Fei felt a warmth in his heart.

His family's health and safety have always been his deepest concern.

As he looked around, his thoughts suddenly shifted in another direction.

Body Refinement Techniques can improve physical fitness, significantly enhancing strength, speed, endurance, and reaction time.

Having a strong physique but not knowing any power generation techniques or fighting moves to deal with actual combat is like having a treasure trove but no key.

My younger sister and the others are alright; they're young, and if they encounter danger, they might be able to escape or struggle thanks to their enhanced physical condition.

However, my parents and aunt are getting old, and in the face of emergencies, physical strength alone may not be enough; they need some practical self-protection skills.

In his previous battles, he mostly relied on his mastery of cold weapons and his absolute speed and strength to overwhelm his opponents; he didn't have any unarmed combat skills.

There weren't the conditions before, but now...

A thought struck him, and he took out his phone, found Yang Zhenguo's number, and dialed it.

The call was answered quickly. The background noise was a bit loud, and you could vaguely hear the sounds of equipment colliding and commands being given. Yang Zhenguo was probably still busy at the base.

"Hey? Instructor Luo? Haha, what made you think of calling me? Did you leave something at the base?" Yang Zhenguo's hearty laughter rang out.

"Commander Yang, there's something I'd like to ask you for a favor," Luo Fei said directly.

"Tell me! Why are you being so polite with me!"

"I'd like to hire a combat instructor to teach my family some basic self-defense techniques," Luo Fei explained his intentions. "A female instructor would be more convenient."

"A female instructor? Teaching your family members martial arts?" Yang Zhenguo paused for a moment on the other end of the phone, then realized what he meant and his tone became excited.

"No problem! Absolutely no problem! Our brigade has an all-female special operations unit, the Youlan Squad! The captain is Chu Yue, and she's the pride of our military region! Her skills are incredible; she's won top three in the all-army women's combat competition! And not only is she a skilled fighter, but the soldiers she trains are all top-notch!"

He patted his chest and assured them.

"I'll arrange for her to come see you first thing tomorrow morning! Do you need her to bring any special training equipment or materials? I'll have her prepare them as well!"

"No special equipment is needed, just come in civilian clothes. The main purpose is to teach some practical techniques and awareness," Luo Fei said. "Thank you for your help, Brigade Commander Yang. Please also thank Captain Chu for me."

"No need to thank me! It's an honor for that girl to have her family member as an instructor! I'll inform her right away!" Yang Zhenguo said swiftly. "By the way, Instructor Luo, what are your family member's plans for learning this?"

"There's no special plan. I just want them to improve their physical fitness and learn some self-defense skills, just in case," Luo Fei said truthfully.

"Understood! Don't worry, leave it to Chu Yue, I guarantee she'll teach it well!"

After hanging up the phone, Luo Fei walked back to the door.

On the lawn in the courtyard, the teaching continued, with Luo Ying's clear and crisp voice giving instructions and the breathing of the elders as they worked hard.

In the night sky, the stars gradually brightened.
