"Math master, you can now take a look at the city in front of you, look at the Oriental Pearl, there is not even scum left. Very good! Let me kill you, take your rational number, and then restore the city of Shanghai. Hacker Tian Lun took the gun, aimed it at Hezhi's temple, and was about to pull the trigger, "Say, what are your last words?" How about making a sacrifice for the sake of the entire Shanghai citizen?"

"I... I don't care, you shoot, shoot!" There was no panicked expression on Hezhi's face, "What? Don't you dare to shoot?"

After Hezhi finished speaking, a light appeared in his hand again, and various mathematical formulas appeared, and then shot towards the hacker's abdomen.

"Ahh It hurts, it hurts!" The hacker covered his abdomen, lay on the ground, and rolled from side to side.

"Good! Little bunny, you're going to die today!" The hacker got up again, and his hand also glowed, conjuring an electric bell. Hezhi was full of strength and ran towards the hacker, but instead of running away, the hacker used his hand to generate electricity and touch the electric bell. The electric bell became loud due to the amplitude being too loud, and Hezhi was about to attack, but he was so frightened by the electric bell that he covered his ears. After a while, Hezhi used her irrational number to destroy the electric bell.

"What? What's going on? My electric bell!"

"Ahh Brother Tian Lun, I'm fighting with you!" Hitch threw Tian Lun to the ground, and was pressed unable to struggle.

Hezhi thought to herself: ..... That's great! It's finally going to end, but what kind of irrational numbers can be used to defeat him?"

"Root number three? No, no, no! Twenty-three sixths of the root number? Nope!"

Hezhi suddenly woke up to the irrational number that could destroy the building before, "It's difficult... Is it π? It's π! But, it's going to make me unconscious! Never mind! Sacrifice yourself!"

With his last breath, Hezhi defeated the hacker with an irrational π, and the hacker's body was slowly turning black, and he said, "Good! Math Wizard, I Lost! I'm sorry! I shouldn't have been, I regret it! Please take care of my daughter Tian Tian for me!"

The hackers are finally reduced to rubble, and Hezhi collapses due to the exhaustion of his physical strength.

5:00 Ward 302

Hezhi opened his eyes, and there was a white ceiling in front of him. She looked left and right, with a hospital gown on her body, and Yang Fan next to the bed, holding a black box. On the right is the doctor, and he says, "Your name is Hezhi?" Well, to tell you the bad news, your body is all depleted of rational and irrational numbers, and I'm afraid you only have three hours to live. I'll teach you how, we just checked your brain, you still have math skills, you can pass on your math skills to your brother before you leave. Make the most of your last three hours. ”

The doctor looked at Yang Fan and bowed, "Farewell!"

Hezhi got up and said, "Yang Fan, what's in the box?"

"Inside? It's your clothes.

Hezhi opened the box and looked at it, it was still a white shirt, a black coat, a black purple skirt with white root number three characters engraved on it, white socks and a pair of black leather shoes, and a purple bow tie.

Hezhi put on the last dress of her life, walked out of the hospital room, and Heli, who was sitting on a stool outside, got up and held Hezhi's hands

For the last time...

It's eight o'clock

Hezhi looked at her watch, but as soon as she looked at the clock, her heart began to feel uncomfortable, she covered her chest, held Heli's hand and said, "Heli, go!" Come with me to a place!"

"Sister! Sister! What's wrong with you!"

"Don't talk so much!"

Hezhi pulled Heli and took him to the rooftop of the hospital, and suddenly! Hezhi threw himself to the ground, spitting out blood.

"Sister!"

When Hezhi finished throwing up, Heli lay her flat on the ground.

"Heli, when the time comes, I can't spend the good years with you anymore."

Heli began to get nervous and said, "Sister, are you not good?"

Hezhi said: "Heli, I regret it very much! Before, if I hadn't given you that pen, that wouldn't have happened. But, it's too late, and I can't undo my fault!"

Hurley asked again, "What do you want to say this?"

Hezhi stretched out his hand and said, "Heli, take you... Reach out, let me pass the mathematical mana to you, sister is gone, you have to take care of yourself! I've already asked Yang Fan!"

"You're gone, what should I do!"

"There's no time, hurry up and reach out!"

"Hezhi!! You're crazy!" Having broken Heli's bottom line, he couldn't help but shout Hezhi's name

But, it was really late, Heli closed his eyes, tears overflowed, he began to cry, the wind began to hang, he said: "Okay.... Well....."

Heli stretched out his hand and held Hezhi, and a magic circle began to appear on the ground. The pattern of this magic array is Zhao Shuang's Pythagorean theorem proof diagram, and there is a π character in the middle, a white circle on the outside, and a circle of pi number

In the last moments, Hezhi had already passed all the mathematical mana to Heli, and Hezhi sacrificed, and her body turned to ashes and was carried away by the gale.

Heli was unconscious on the ground, and a group of doctors ran to the rooftop.
