The sharp tip of the spear landed perfectly on the guy's forehead. But the spear was only redirected, and it didn't even manage to leave a scratch on the other party, as the skin on his forehead was literally made of diamonds.
"That guy's ability isn't bad for a C rank." Anthony couldn't help but praise.
After all, being able to turn his entire body into a diamond, which is considered as the toughest mineral on the planet! Even if you pour magma directly into him, he would come out unscathed.
"Wow! Who is that girl? She can hold herself against three guys."
"Her ability is amazing. I wonder what is her name."
"She seems pretty young. I think she is an heir to a noble family with that kind of talent."
The people on the side watched Fey fight the robbers. They started to gossip as soon as the danger came out of their way. Now, Fey became their topic because of how she bravely faced the group of robbers head-on.
While, Fein and the others just observed from the side, not at all worried about Fey.
Suddenly, Jonathan stood up on the ground while clutching his forehead with a hideous expression. Then a coin flew out of his hands and rotated at an incredible speed. Lightning covered the coin, which ripped the surrounding air.
Jonathan aimed the lightning-covered coin at Fey, who was currently using her spear trying to single out the diamond-covered guy.
'This isn't good.' Fein took out his sword, intending to intercept the floating coin above the other party's hands. He could feel the lethality contained in the coin after the lightning enveloped it.
'Since you want to harm my sister, then you have to be prepared to lose your life in exchange.'
Fein won't tolerate anything that could harm his sister. Just thinking of her getting hurt is enough to ruin his day. So, with a flick of his hand, he unsheathed his sword within 0.1 seconds. A sword light emerged from the void. Fortunately, Fein managed to restrain his emotions.
The sword light came as fast as it appeared. Blood splattered in the air, as the sword slightly went through Jonathan's hand without the slightest resistance.
"It hurts!" Jonathan fell to the ground with a thud. Blood gushed from his hands without a sign of stopping. One can also see a neatly divided coin lying beside the hand.
'That was fast. I didn't even see his hands move.' Anthony felt that... if he was the one at receiving end of that terrifying light. He won't be able to do anything. 'With that kind of speed. He can literally murder everyone here at any time.'
This is also the first time Anthony witnessed Fein's strength after a long time. He could only describe it as one flick, one kill. Anthony knew that as long as Fein's didn't face an SS-ranked opponent. He could literally one hit anyone to death.
The diamond-skin guy was already becoming more confident as Fey couldn't do anything with his diamond skin. No matter how she tried to exert her strength through her spear, she was unable to hurt him.
But after he saw his companion fall with that sword light. He couldn't help but feel nervous in an instant.
The guy took a glance at the Fein. He knew that even with his proud diamond defense, the white light that appeared earlier could split him apart. He didn't need to test it with his body, as his instinct warned him of danger when it appeared.
Thinking of this, the man bowed at Fein and his group. Then he pleaded with all his might. "I give up. Please spare us."
Fey looked at his brother subconsciously.
"Well, since he still has some awareness. Just let them go." Fein responded with a laid-back demeanor.
He was simply too lazy to bother with such small fries.
Anthony smiled at the robbers. "Did you hear my friend? Now scram! Before we changed our mind."
"Thank you." The diamond skin that wraps his body reverted, and he instantly came back to normal.
Then he shook the body of his companions to wake them up. After that, they scurried out of the way, as if a demon were chasing them.
After the small episode, Fein and his company visited almost all the tourist spots in the Felmundia country. They only returned at night using the Ranger's Eye exclusive carriage.
...
The next day, Fein held a dark green potion in his hand and he smiled at Brick beside him who has dark heavy bags below his eyes.
"We finally perfected the potion! This potion will be the key for us to be perfect creatures, hahaha!" Fein laughed unrestrainedly.
His laughter echoed through the Laboratory. Brick looked fervently at the dark green potion on his partner's hand. After countless animal clinical trials, the rate of error and possibility of gene collapse was minimized to less than one percent!
He felt happy and proud that they manage to create another great invention that could literally alter human genes to perfection! He had put all his brain and energy into this endeavor.
"It was thanks to your unconventional theory." Brick laughed and patted his partner's back with joy apparent on his face.
"Well, I'll configure it to suit my gene first. After my turn, we will also configure the potion to be compatible with your DNA." Fein smiled.
The current potion in his hands was specifically formulated using his unique gene code as the basis. So, he's the only one who can use the potion. If others used this, it would instantly result in gene collapse or uncontrollable gene mutation.
"Well, you know what to do."
As he said this, Fein lay inside a cabin. Brick Norty picked up the cables on the ground and put them on Fein's body.
Fein has already his eyes closed. So, the procedure is up to Brick.
Brick took out a syringe on an experimental table, and transferred the dark green liquid to it. Then he walked to the cabin and injected the syringe containing green liquid into Fein's shoulders.
A mad light flickered in Brick's eyes after the syringe was fully emptied. "Here comes the emergence of a human with perfect genes."
