As a trainer, he has the rain trait

After class, the students left the classroom one after another.

Xu Wu yawned as he met up with Zhilin and the others.

"It's like this, why don't you ask for a leave?" Zhilin asked in confusion.

"No need, I can still attend the class. It's the only class today anyway."

Zhilin gave a thumbs up. He was so sleepy that he could still hear what the teacher said. It was a skill that most people couldn't do.

Xu Wu went back to the dormitory in a daze to catch up on some sleep, not even planning to eat. Zhu Yu planned to go out for dinner with Yu Huan and the other sisters, so Zhi Lin had to go to the cafeteria alone to eat.

Zhilin was fiddling with the rice on his plate somewhat absentmindedly, sorting out his plans for the school year in his mind.

The training plan for Dragonite still needs to continue, but it is already a mature Pokémon and will practice diligently on its own, so you don't need to worry too much about it.

The evolution of the chou chou fish needs to be put on the agenda. It can't just keep being a salted fish like this.

I can't neglect my studies as a breeder with Professor Lin. The Shining Zubat that I like is also with Professor Lin, so I have to get closer to it.

There are also the usual classes and meditations that have to continue.

There are still a lot of things to do, so I have to get busy~

......

More than a month later, Nurturing College.

Lin Qingping is giving Zhilin special treatment.

"Energy Cubes, also known as Poké Cubes, are mostly square in shape and can be used to enhance various stats of Pokémon. They also contain the energy needed for Pokémon's growth."

"There are two methods for making energy cubes: traditional and mechanical. The traditional method is more complicated and time-consuming, so it has been eliminated by the public."

"Mechanical production uses a tree fruit mixer, which is more efficient and has guaranteed quality."

Zhilin raised his hand to indicate, and waited for Lin Qingping to nod before asking, "So, energy cubes made using the ancient method can be of higher quality?"

Lin Qingping nodded. "Masters of the ancient method meticulously crafted the blocks, and there's indeed a small chance of producing perfect energy cubes. This isn't possible with machines, so some places insist on using the ancient method, and the Alliance is also providing subsidies to support them."

"But I don't recommend you learn the ancient methods. You are a trainer and breeder at the same time, so you don't have that much time to learn."

Zhilin was not too disappointed, he was just a little interested.

Lin Qingping continued the lesson, "Mechanical production of energy cubes consists of five main steps: crushing, precipitation, purification, solidification, and compression."

"Crushing and sedimentation focus on rotation speed, purification tests the node, and solidification and compression require attention to temperature. These are all difficult points. Even the slightest mistake will significantly reduce the quality."

"Energy cubes are divided into six grades: poor, low, medium, high, top-tier, and perfect. Poor and perfect qualities are rare on the market."

Zhilin's mouth twitched. This is nonsense. It has become a bad product. Who would sell it?

"Poor quality doesn't mean it's ineffective. On the contrary, poor quality energy cubes can provide more nutrients than the raw fruit, although not by much."

"The reason there are fewer inferior products is because they taste inferior. The nutritional content is pretty much the same anyway, so you'll definitely choose the berries that taste better. If you really want to be conscious of the nutritional value, just eat one more berry."

Zhilin thought of his two spoiled Pokémon and said with some worry, "If I make a Dragonite, won't it be a waste if they don't eat it?"

Lin Qingping rolled his eyes at Zhilin and said, "You might not even be able to make a decent product the first time, so you think it would be a waste."

Zhilin scratched his head and said, "Yeah, let's do it first."

Under Professor Lin’s hands-on instruction, Zhilin began to make his first energy cube.

The fruit mixer is a refrigerator-sized machine with a display screen on the side that can adjust the number of blades, speed, rotation time, temperature, etc.

Zhilin tried the simplest apple fruit energy block. For a single fruit, there is no need to consider the compatibility between fruits, so it is perfect for practicing.

According to the requirements of the recipe, Zhilin set the parameters such as double knives, speed 2rps, rotation time 2min, etc., put four apples into the feed port, and started the machine.

The mixer began to hum softly.

Zhilin leaned against the observation window, carefully watching the apples being chopped, ensuring they were evenly mixed. When they felt they were about the right size, he pressed the juice button, and the yellowish juice flowed into the container. After passing through the filter, it appeared quite clear.

Zhilin asked Lin Qingping nervously, "Is this okay?"

Lin Qingping took a quick look and nodded slightly, "Not bad."

Only after receiving confirmation did Zhilin continue with the next steps.

Smooth precipitation, evaporation purification, heating solidification, and mechanical compression.

Three minutes passed after these steps were completed. Zhilin looked dejectedly at the dark mass of unknown object in front of him.

This loose paste is obviously unable to be formed into energy cubes.

Lin Qingping was used to it. "It's normal. I've never seen anyone succeed in one try."

Then he explained it to Zhilin.

"Parameter setting is crucial. For different fruit types, the stirring speed needs to be fine-tuned. You can't just stick to the recipe. For example, the apples were a little overripe, and if you turned the speed too fast, it would destroy the fruit's nutrients. This kind of fine-tuning requires constant exploration through practice."

Zhilin listened carefully and nodded continuously.

Lin Qingping continued, "Also, the timing wasn't right. Low temperatures require more time to completely evaporate the water. If the time is too short, the purified concentration won't be high enough."

"Your key problem lies in the purification and crystallization steps. Just practice more and it will be fine."

After listening to the explanation, Zhilin summed up the lessons learned this time, cheered up and started making energy blocks again...

Late at night, Zhilin stared at the few black, granular cubes before him, feeling almost heartbroken. He'd spent the entire night trying eighteen times before finally succeeding. Not only was the quality poor, but only five of the theoretical twelve finished products had formed—less than half.

Lin Qingping was quite satisfied. He patted Zhilin on the shoulder and comforted him, "Success within twenty attempts is already a very good result. Don't be discouraged."

Zhilin felt a little better after hearing this, but he still worried, "Even the simplest ones take several days to practice. How long will it take to master the production of all the energy blocks?"

"Making energy cubes is a delicate process. You can't rush for results; you need to be patient and careful. Take each step seriously and adjust your production methods in a timely manner. Sooner or later, you will be able to make high-quality energy cubes."

"And if you master the basics, you'll be able to make other energy blocks easily and master them faster."

Zhilin nodded and secretly made up his mind to master the production of all energy blocks this school year.
