The clouds float spontaneously in the sky, and the towering mountains had almost reached them, and it's just three meters away from making contact with each other.

On top of the mountain, white grasses covered the ground and the vibrant enormous trees gave it a green appearance when someone look from afar.

Ting! ting!

Two human figures clashed with each other, the male one kept changing his weapon in the middle of the battle, while the female one used a blood scythe as she struggle to parry the uncanny attack of the man.

"Your master of Scythe is getting better, but I suggest you practice more on your footwork and body coordination," Fein uttered as he appeared behind Sofia.

Sofia's eyes widened because she felt a sharp metallic object on her neck.

"You also need to train your reaction speed."

Fein's deep voice entered her ear and she felt a warm breath in her ears.

"Then you have to help me, I still have to train my energy control..." Sofia turned her head at him with a helpless expression.

"Your physical training can be set aside for now. You had reached a satisfactory level in your physique especially after consuming the blood purification pill."

Sofia's eyes lit up, "Doesn't that mean that I can already start training my energy control?"

"Yes, and we will start now." Fein chuckled seeing her enthusiasm. "Pay attention to my instructions and follow them."

Sofia nodded as she perked her ears closely afraid that she would miss some words from his mouth.

Seriously? your hearing can even distinguish sound kilometers away. Why are you propping your ears exaggeratedly like that? Fein silently complained in his heart.He sighed for a while before he continued. "First, create a ball of dark energy, blood energy, and degu energy."

He stopped as he looked at Sofia who nodded. She spread her hands, and three balls of energy appeared in different colors. One is completely dark, silent, and cold. While in the middle is the same ball of energy with a shade of violet, and it exudes a violet mist. On the right side of it, is an that kept beating like a heart, it was blood red that exudes the aura of life.

"Well, you already have a good foundation in your energy control..." Fein smiled.

If Fein's energy control is Level 10, then Sofia should be at level 8, which is not that bad considering Fein has A-level talent in anything and he also prioritizes his energy manipulation right from the start, while Sofia only got this far after practicing hard with a bit of talent.

Sofia smiled after receiving his acknowledgment. "What's next?"

"Hmmm... this would be the hard part of the training. Destruction energy is an energy that is very difficult to control due to its unstable property. This also means that it's an excellent means to practice energy control."

Fein stopped for a moment before reorganizing his thoughts.

"What we have to do is to make your degu energy act as a stabilizer, balancing the dark energy and blood energy. With that, you can control the destruction longer and it won't take a toll on your body."

The eyes Sofia showed a hint of enlightenment with every word that came out of his mouth. Everything he said had substance and logical explanations

That's why he became a Scientist?Sofia looked at Fein who looked more like a samurai.

Sofia began to follow his instructions, the three energy balls started to get close to each other under her control.

"You have to place the degu energy in the middle to form an equilibrium with each other."

Fein started guiding her, with his guidance, Sofia smoothly fused the two with the degu energy becoming the core of the two energy, therefore, forming a balance. The three energy became one forming destruction energy, but this time, Sofia felt more at ease."It's really easier to control, but I felt that the power it contains isn't as violent as the first ones," Sofia muttered.

"Of course, but it only reduces the destructiveness, but as a result, the energy became more stable. With that, you can use it with a longer duration in future fights." Fein looked at the purple energy with a wide grin.

"But if you want to use the more destructive one, just remove the degu energy and the damage output would return and the duration would become shorter."

Sofia nodded with understanding.

"But..." Fein placed his hand behind his back and continued. "That's just a solution for the short term, improving your energy control is the real solution. Now, you need to create stable 'Destructive Energies' as much as you can while maintaining them.."

"So I just have to increase the quantity and prevent them from exploding right?"

Fein just smiled at her as a confirmation.

Just like that, Sofia created another six destructive energy with ease, then she followed that by adding another four but it was more laborious than before. After attempting to create another one, Sofia sweated profusely, and the 11th ball was created.

Suddenly Sofia fell to the ground, Fein who was maintaining constant vigilance appeared in a timely manner and dashed far away from the Destructive Energy Balls.

Boom! Boom! Boom!

A huge explosion appeared, and a purple light illuminated the whole top of the mountain.

Fein looks at the missing half of the mountain, after dashing away, he had to use his 'Ghecko Substitution' because he knew more than anyone how frightening the destructive power of 'Aiki' is even after their power was greatly reduced.

"I feel weak all over my body," Sofia whispered, her face paled after exerting all her energy.

Fein shrugged his shoulder and says. "That's normal, don't expect that the training would become smooth sailing. Though you shouldn't train when you don't have someone watching you or else the result would be like that."

Fein pointed to the mountain that doesn't look like a mountain anymore.

"I get it, I'm not dumb enough to practice that kind of thing anywhere." Sofia's sighed.

She didn't expect her training regiment to be so hard and perilous. She still has to find a place to safely train, if she did it to their mansion, her father would scold her.
