“There are still three left…” The teacher had just spoken when another student rushed over. “This is the last one.”

Brian Walker was still fifty meters away from the person in front. Seeing that she was about to reach the teacher, she wiped her sweat, gritted her teeth, and sprinted forward, finally overtaking the person ahead and grabbing the last nutrient solution.

As she ran, she poured the nutrient solution into her mouth. The moment she drank it, Brian Walker realized that this nutrient solution was different from the problematic ones she had picked up from the junkyard. As soon as it entered her stomach, a surge of energy instantly filled her whole body.

Brian Walker felt like she could run ten more laps.

The fifty students who managed to grab the nutrient solution were basically the first to finish the task, but after running twenty laps, they collapsed directly onto the ground.

Brian Walker couldn’t help but marvel at how survival makes people strong. Back in her original world, after work, she would sit if she could, and lie down if she could sit. Now, at just seven years old, she could actually run this far.

The first day of school was spent running. By the time school was over, many students still hadn’t finished their twenty laps. The teacher just waved his hand: “Class dismissed. Those who haven’t finished can leave too.”

Brian Walker checked the time—it was just past five o’clock. She had missed the bus.

In this world, you could also take a taxi—actually, a flying car—but it was a bit expensive. Brian Walker thought for a moment and decided to check out the materials market first.

As the name suggests, the materials market was a place that sold all kinds of materials. Brian Walker originally planned to buy some materials to make an electric vehicle so she could travel freely, but when she got there, she found that all the materials were unfamiliar to her.

After checking out several shops, Brian Walker finally discovered what the energy source in this world was—gray crystal.

Gray crystal was an energy source mined by the Federation. It could directly power mechas, but ordinary households couldn’t use it; they could only use something called a crystal card, which contained processed gray crystal.

A thin card contained energy and could power all kinds of tools. When the energy in the crystal card was used up, it could be recharged. This was a bit like electricity in Brian Walker’s original world.

Brian Walker spent six hundred star coins to buy a crystal card, which had a balance of five hundred. She planned to use it to power her electric vehicle. She also bought a welding gun; the one she had been using was an old one left by an elder and didn’t perform well enough.

After walking through the entire materials street and getting to know all sorts of new materials, it was already ten o’clock at night. Brian Walker walked out of the alley and saw a shop selling mechas, so she went in.

The shop was luxuriously decorated, but there were only three mechas on display. Brian Walker looked closely; the three mechas were all different types and looked very nice, but… according to the information she had found on the light brain, mechas were used for combat, and she couldn’t see any part of these three mechas that could be used to attack insect beasts.

She voiced her thoughts, and a customer nearby who was also looking at the mechas laughed, “Kid, these are ornamental mechas, not combat mechas. The military’s mechas would never be sold on the market.”

So that’s how it was.

Brian Walker lingered in the shop for a while longer. Each of the three mechas was more expensive than the last, with the cheapest costing five million star coins. But since gold itself was expensive—one gram cost a hundred thousand star coins—it was no wonder the mechas were so pricey.

After leaving the shop, Brian Walker spent fifty star coins to take a taxi home. She stayed up all night and finally made a simple version of an ‘electric vehicle’. Early the next morning, she rode it to school.

Just as she arrived at the school gate, a flying vehicle swooped down and stopped above her. Emma Carter got out and waved at her, “Brian Walker.”

“What kind of vehicle is this?” Emma Carter circled around her electric vehicle. “Is it for sale?”

Brian Walker: “Fifty thousand star coins.”

“Forget it.” Emma Carter glanced at the back seat. “Can I sit here? Give me a ride into school.”

“Five hundred star coins per trip.”

“Aren’t we friends?”

“I’m broke.”

Emma Carter raised his hand and transferred five hundred star coins to Brian Walker, then plopped down on the back seat. “Done.”

Watching this strange thing move, which was much faster than the previous tricycle, Emma Carter became even more convinced that Brian Walker was the child of a master. This vehicle was probably also made by a master.

The last tricycle had been taken apart by Emma Carter’s family tutor. There was nothing particularly ingenious about its structure, and it had to be powered by human effort. It was just a novelty, and the tutor said it had no research value. This one was probably about the same.

“I’m in Class A1. Which class are you in?” Emma Carter asked Brian Walker, who was riding in front.

“B5.”

Emma Carter was stunned. “Class B? Aren’t you a mecha engineer trainee? How did you end up as a mecha soldier trainee?”

“Is that not allowed?” Brian Walker replied calmly.

If it weren’t for being forced by life, who wouldn’t want to be a mecha engineer trainee?

“It’s fine. Being a mecha soldier trainee is good too.”

The two parted ways. Brian Walker found her class, picked an empty seat, and sat down, not knowing what they would be learning today.

The teacher was still the same one. As soon as the bell rang, he stood at the podium and displayed the class schedule.

After reading it, Brian Walker felt a chill in her heart: weighted running, combat, dagger techniques… all physical training, with only one day of academic classes.

Why would a frail former engineer like her need to learn these things?
