The robot can stand guard for Katy, Zhang Su is satisfied, Katy is there every day to watch the door, and she feels uncomfortable, so let the robot be the security guard.

In this way, he can also take Katy to the back mountains to explore the secrets, and leave the daily defense to the robots.

When the little witches saw the robot, they subconsciously retreated, afraid that it would suddenly burst out and hurt people. The appearance of this robot is indeed sharp enough to scare any potential enemy.

"From now on, this will be our shelter's defense robot." Zhang Su announced, "It will make this place safer." ”

"Hmph, it turns out that the teacher occasionally brings cool things." Saho crossed his waist with both hands.

"It seems like something terrible." Muroka listens to the movement, the metal rubs, lifeless, but can speak.

Its glittering armor makes it agile enough to walk with the precision of a robot and the elegance of a top model.

"Who are you?" Saho asked boldly.

"I'm a Taiwan Defender robot, our predecessor was a series of multi-functional civilian robots, my model of the same model is active all over the world, as for me, you can call me Roy!" The bot responds like a stream.

"Eat me a dart!" Saho raised her hands in the air, swung the shadow magic in her hand, and fired it at Roy.

Roy stepped back a few centimeters with astonishing sensitivity, as fast as a whirlwind, calculating the distance between the tip of the knife, and dodging the attack slightly, without being injured.

"Ugh! So fast! "Saho also sees the gap.

"Don't bully it!" The edge weave pulls the early spike.

"'Fight every day, live a long and healthy life,' just kidding, I'm metalwork." Roy spread his hands.

The headquarters did send something good, Zhang Su said secretly.

With this high-precision robot, if a small person comes to commit it, I'm afraid it will be a matter of a gun.

After everyone met and chatted with Roy, before they knew it, it was time for lunch, and they dispersed one after another.

The last person to see Roy was Truebow.

At this point, the others were gone, leaving Roy still eager to try, and the smiling face on his chest looked very happy.

Carrying a new backpack sent by Zhang Su, which was full of textbooks and tutorial books, Zhen Gong came to the door, took a deep breath, and walked towards the unfamiliar robot.

"According to the files entered before, there is a 97.5% probability that you are a 'real bow', and there is a 2.5% probability that my lens has not been wiped clean." Roy scan.

"Robots? Can you help me with math? Makomi sat down on the threshold, taking out pen and paper, textbooks, and scratch paper.

"I can teach you how to shoot, 'bang bang' to protect our homeland." Roy jumped on the spot, boxing.

"I just want to ask you to teach me math, I heard that artificial intelligence is super powerful." Mayuki rummaged through his backpack for his mistakes.

"It's true, AI neural networks have quite a lot of computing power, although I exist to fight. But the first law of robots is to obey all your commands. Roy spread his hands.

"I see!" True Bow hurriedly replied, "Can you teach me math now?" ”

"Absolutely! But first, take a moment to take in the amazing sights that surround us. Roy stretched out his mechanical arms, "How do you count the street trees on either side of the steps?" What is the volume of grains piled up in cones? How do the rocks on our trails overlap to form a wonderful recursive structure? ”

"I don't understand, I don't care, I have to study, you can help me look at these topics." Makomi didn't have time to think about things other than doing the question.

She picked up her notebook and threw it at Roy's camera.

"Don't rush! After years of high-pressure studying, you will hate learning from the bottom of your heart and will no longer accept any form of learning. In the next 80 years, you will reap the consequences, and stopping learning is the greatest vice of man. Roy looked at the real bow.

"Don't say it again, I want to go to New University of Tokyo, so, please guide me!" Makoku said resolutely.

That's what she lives for.

"No, no, no, no, no." Roy jumped back, "Understanding is much more important than mastering the topic." Math too, you have to fall in love with the beauty of math first, otherwise you will die of exhaustion. You can't replace your own battery. ”

"I can!" True Bow took a ball of "joy" magic out of her heart, and then slapped it into her mind, her emotions overflowing with infinite vitality, "Now I'm happy." ”

"Magic! The Joy Pathway, one of the ways that is completely ineffective against bots...... Your pleasure is too cheap! Roy judged.

"Nope." Makoku shook his head, "Because I have experienced pain and sorrow, I cherish the joy in my heart very much. I know what a beautiful thing joy is better than those outside the walls who have been happy all their lives. ”

Roy couldn't argue with anything more.

So in addition to the job of the robot janitor, Roy the robot has become a one-on-one math teacher, but he is also competent. Mathematics, this stumbling block in the real bow college entrance examination is being eradicated.

……

The next day.

On the playground, Zhang Su saw from afar that Carty was fighting with Roy, as if he didn't know how to get on the bar with him.

Katy regards the Anxin House as her territory, and now Roy patrols the prison gate every day, Katy probably thinks that foreign animals are coming, so she is very angry and must be separated from Roy. Zhang Su guessed.

Dressed in a black tank top and military pants, Katie was muscular, imposing, bare-handed, with short hair and gritted teeth, staring at Roy as if wondering if the robot was worthy of being compared to her.

"Have fun, friend!" Roy said happily.

It's ready to go.

The slender humanoid frame of the machine seemed thin to Katy, but its computing core and combat procedures were advanced enough to far exceed the limits of biology.

Katy let out a defiant roar at Roy, enough to wake all the little witches out of their dorms.

She lunged at her, her fist as fast as lightning.

Roy deftly flicked his arm off Katy's attack, and Katie felt like he had hit a whole piece of rubber, making a muffled sound, and the force was completely scattered across the surface, but he lost his balance due to the forward momentum, staggered two steps, and nearly fell, and leaned forward sharply.

Roy didn't chase after her, which made her even more irritable. If it had struck her hard with a knife at this point, she would have thought it would be fair.

"Whew......" Katy was suspicious. Why can such a robot stop a full-bodied witch?

Zhang Su was on the side, but he could see it.

The key is "pre-reading".

Kati's attacks opened and closed wide, and the movements of his shoulders and feet were too obvious.

In the eyes of ordinary people, it is fast and fast, enough to rampage and crush everything. But in Roy's combat calculation system, there are traces and flaws.

When you see the movement of your shoulders, you can understand the direction of your fists; Seeing the displacement of her hip allows her to understand where she is going to move next.

So what will Katie do? Zhang Su observed carefully.

Carty switched tactics and threw a frontal punch to meet Roy's camera, blocking his view.

The next second, she shook her body, changed direction and swept her leg, and kicked Roy in the left calf!

Bang!

Katie's kicks were fast and ferocious, and her legs exploded like bursting shocks.

Roy was hit in his left leg, and the soles of his feet slid off the ground, losing his balance and about to fall!

She let out a triumphant roar in her heart, this leg kick was a dangerous move, Katie had practiced countless times, and many of the enemy's leg bones were broken by a kick.

"Oops!" Suddenly, Roy adjusted the structure of his whole body's output.

When its left leg is hit, its right leg explodes with a burst of force, making a buzzing sound, and nails it to the ground like roots, responsible for providing a fulcrum for the whole body, like an iron hook sinking into an anchor, and it is firmly fixed!

Immediately afterwards, its entire waist also performed acrobatic twisting, sharp rotation, and its left leg was hooked up, in a bent knee position, like a top ballet dancer!

After regaining its balance, it made a defensive stance with both arms, and made a defensive gesture with two punches, forcing Katy back without dead ends!

It doesn't leak, like a silver tumbler, and it won't be crushed no matter what.

This movement is completely mechanical, and unless humans can twist their lumbar vertebrae, there is no way to reproduce it.

"Did you see what I just did? I did all sorts of really good moves! Wait, are you listening? Roy's right foot is on his own, and his left leg is playfully swinging back and forth, suggesting that the amputated leg kick that Carty just had just made was useless.

Katy's vest was soaked in sweat, and she roared, tired and bored, unable to overcome it.

When she saw Zhang Su, she turned her head even more annoyed, walked out, and returned to her "dragon's nest", and Roy didn't chase after her.

"Oops, I beat her on purpose." Roy wipes his camera.

This robot sometimes speaks very sarcastically, Zhang Su said secretly.

He saw a palm-sized dent where Roy was kicked, and Kati's strength was really terrifying, and he was able to break through this advanced robot before he could burst out with all his strength. I just don't know how much it costs to repair.

"Do your job." Zhang Su tells Roy to go on patrol, and then goes to the Dragon's Lair to comfort Katy.

Katie lay on all fours on his heap of collected weapons.

These weapons are like the gold coins and treasures collected by the evil dragon, and Kati will not give them up when he dies.

She closed her eyes, as if she had completely given up on her fighting spirit, and looked like her self-esteem had been wounded, and she stayed with the dead souls.

In this case, Zhang Su can only use his methods to comfort Kati.

He stepped forward and stretched out his hand to extend the invitation: "Katy, how do you feel?" ”

Katie opened one eye and looked at Zhang Su.

"You...... And that lotus mist ......," she said in a hoarse voice.

Zhang Su suddenly realized. It turns out that Katy's abnormal behavior is because he sees himself and Lianwu?

"Let's go, we're going to hunt. We go to the mountains, and no one will disturb us. Zhang Su shook one of Katy's hands.

She turned over slowly and fell into Zhang Su's arms, heavy and hot.
