Quadratic Element from Zero

Firmly, he said, "Teacher, please start teaching me!"

"it is good……"

Qiye nodded and said, "Your talent is very good, and you are the son of luck in this world. Under my teaching, it is not impossible for the Demon King to achieve.

...Now, disperse your artifacts and attack with all your might! "

"Yes!"

Hyoudou Issei nodded, the right hand that was originally caged returned to its original shape, and both hands clenched fists and rushed towards Qiye.

"what!"

The dark energy in the body was poured into both fists, and with the strength of the whole body, it smashed towards Qiye.

"Stupid! Who made you try your best!"

Qiye flashed the punch at random, and then knocked Hyoudou Issei to the ground, saying: "Without the assurance of one-hit kill, never fight.

Do your best!Once your attack fails, others will catch the loophole! "

"Remember! You can't use all your strength when fighting!"

Qiye waved at Hyoudou Issei on the ground and said, "Come again!"

"drink!"

Hyoudou Issei got up from the ground and rushed over again, the strength in his hand was a little weaker than before.

"boom!"

Qiye nodded, and after avoiding this attack, he beat Hingdou Issei to the ground again, and said, "There is progress, but it is not enough! Let you spare a bit of strength,

It's not that you don't need it!This part of the force is to let you adapt to the situation! "

"Mouth!"

"boom!"

"The attack is too direct! You can see it at a glance!"

"what!"

"boom!"

"What are you doing! Take it seriously!"

"..."

Half a month later, under the non-stop teaching of seven nights, Hyoudou Issei's attack finally took shape. It was no longer the kind of gangster fight that he used to fight with one punch and one step at a time.

There is clearly a rule of thumb.

"Yes, Not Bad……"

Catching Hyoudou Issei's fist, Qiye nodded with satisfaction and said, "I have nothing to teach you about fighting skills... Go out behind closed doors.

It's not the same, what you lack now is the experience of actual combat..."

Hyoudou Issei frowned and said, "Teacher, what should I do then?"

"If you lack actual combat, then go to experience actual combat..."

Qiye looked at the setting sun in the distance and said, "My disciple is not a weak person, this city is run by Rias's family, and yesterday I have already asked her from her.

Got the pass there, and from now on, you're in charge of the city's safety, cleaning up lost demons and malicious outsiders..."

"Yes!"

Hyoudou Issei nodded, and suddenly he turned his eyes to the right and said, "Teacher, is this?"

Qiye nodded and said, "Say that Cao Cao and Cao Cao are here, your opponent is already here..."

"Seven nights……"

At this time, a bookmark-style piece of paper flew out from the pocket of Qiye's uniform, and Rias's voice came from the piece of paper engraved with the magic circle, saying: "From

The Grand Duke's crusade commission..."

Lost Demon.

Servants absorbed by the knighted demons betray their masters, or kill their masters, thus becoming masterless demons, which rarely happens.

Demons are so powerful that they can't be compared to when they were still humans.

Therefore, it is normal for demons who want to use this power on themselves to appear.

These demons leave their masters and go about their business everywhere.

Simply put, it's a wild dog.

Wild dogs can cause harm, and as long as they are found, the original owner, or other demons, can be killed.That's the devil's rule.

Other powers also see lost demons as a danger, whether angels or fallen angels, they will kill them if they find them.

It is said that there is nothing more terrifying than a demon who escapes from conditioning and returns to the wild.

When Nanaya and Hyoudou Issei rushed to the ruins in the suburbs, Rias and her family had been waiting for a long time.
