Fein can dodge the attack if he canceled the suppression of his strength, but that would be considered cheating. So he just used his flashing dash technique to let the attack land on his shoulder.

THUD!

"Good job." Fein patted his shoulder.

Fey felt happy after she finally manage to hit her brother this time. Even at the fact that his strength was suppressed, she still treat it as an achievement.

Fein smiled, seeing the joy on his sister's face. 'I could use Ghecko Substitution, though,' he thought in his head.

"Continue, although your timing improves. I want to see your main fighting style." Fein said.

'Probe!'

'Hmm... That's why I felt that her speed was a bit faster than normal C-rank,' Fein thought as he saw the plus sign on his sister's attribute.

He knew that the training regime that he designed for her had caused her basic stats to grow so fast. After all, Fein gave her sister the best condition for training. His personal invention and his 'Purple Yen' potion that could boost her training speed. 'I'm really the best brother. I hope I didn't spoil her that much.' he sighed.

Due to him not having a sister in his past life, he feels energetic that he has Fey in this life. He realized that having a sister isn't that bad, and his sister also took the same path. Now what he had to do as a good brother is to guide her.

"Okay," Fey nodded.

'This time I won't go easy with you,' Fein manipulated the bones in his arms.

They turned into flexible whips. Fey became wary when she saw the strange move of her brother. She jumped and activated her ability. Her body became blurry as she entered her phasing state. Just like that, when she fell to the ground, her entire body went through it with ease. When she felt the familiar feeling of nothingness, Fey deactivated her ability.

A strong repulsive force pushed her onto the ground and she flew back to where she came from at the speed of sound! This time, she could confidently change her directions and control her body. She had practiced this move for a whole month. She suffered that all the bones in her body had experienced being broken. Fey hit walls, trees, and other obstructions just to master her ability. And now, she finally got the hang of it.historical

THUD! THUD! THUD!

Fein stared at Fey, who kept bouncing back and forth through the surface of the environment like a cannonball. He carefully observed her phase through trees and get repulsed, then phased through the ground and used the repulsive force to boost her speed. Every time she phased and got repulsed, her speed would increase by at least two times and as time goes by, she would only keep getting faster and faster.

After a few minutes, she only appeared as after images in Fein's vision. 'It seems she had really understood how her ability works.'

'Chess Perception!'

Just like that, Fein entered a familiar state. He felt the world move slower than usual, and the surrounding became a chessboard in his eyes. Every minute detail can't escape his perception and she could finally follow Fey in his eyes.

Fey looked at his brother. She suddenly felt that her brother had a different air, and she saw his eyes following her. 'Huh!? he could still see me at this speed?' she quickly redirected her body to Fein's direction and clenched her fist.

Suddenly, Fey appeared in front of Fein with her fist direction of Fein's head. Fein didn't flinch at this, as he had already anticipated all this.

Fein lashed his hands with the flexility of whips at his sister. They appeared like an afterimage. The accuracy and speed made his attack as sharp as a grinder due to the buff the 'Chess Perception' provided.

Fey knew that she had to dodge this or else her fist would suffer. Just seeing the sharpness of his brother's whip arms had already made her nervous.

Because she's mid-air, she can't really control her body, so she had to activate her ability.

Just like that, Fein's furious sharp attack went through Fey's body one after another. They landed on the trees behind Fey, which sliced them to a hundred small pieces!

Fey canceled her ability and turned her head at her back. When she saw the outcome of the trees, she felt her blood slow down. If her brother's whip-hands had hit her, she would have the same result as those trees. This reminded her just how dangerous the degu society really is!

Fein retracted his hand and looked at his sister. "Your improvement surprised me. You really worked very hard." he gave Fey a smile.

"But..."

"No buts... The result is already very good. If it's another person, your fist would have already bashed a person's head." Fein chuckled. "And I had to enter my special state just to keep up with the speed your ability provided you. It's something to be proud of. Honestly, your ability is a perfect for escape, feints, and high-speed movement. As long as you stay in phasing state, no one would be able to hit you."

Fey bit her lips, as she couldn't help but recall the hard work she had gone through the past year, and the intense training in the past few days.

"Thank you." Fey bowed her head at her brother.

Fein walked beside his sister and patted her shoulders gently. "You don't have to thank me. All of this is the result of your hard work."

"But you had provided me with magical potions and the best training equipment. Although I don't know their prices, I know just how valuable those things are." Fey stared at Fein and said gratefully.

"Those are small things. We're family. I can only provide things that are within my ability,"
