At 10:00 a.m. on June 29, the Tenth People's Hospital Affiliated to Tongji University, Shanghai - operating room

"Why is this child's lower body so swollen?" The female doctor who was watching on the side asked, and the male doctor said while operating on Tian Tian: "This child was beaten by his father!"

"Huh?" The doctors in the operating room began to be surprised.

"This is the first time I've encountered it as a doctor, and I found out yesterday when I was doing a CT scan on her, and I suddenly remembered when I was a child." At this time, the male doctor began to laugh, "When I was a child, I was very naughty and disobedient, so I was beaten by my father!" Every time I hit me, it wasn't that bad, but this girl is amazing! Breaking the Guinness Book of Records!"

The male doctor's words amused the doctors in the operating room.

"Okay, no kidding, check the patient's vital signs, I'm going to stitch up." Okay, the vital signs are basically stable. ”

After a while....

"Click, click." The doctor took a stapler-like stapler to close Tian Tian's wound, and then pushed Tian Tian out of the operating room.

ward

He Li bought nutritional products for Tian Tian from outside, and then returned to the ward, seeing that Tian Tian had not woken up yet, He Li was very worried and said: "This Tian Tian has slept for six hours, did the doctor make the dose bigger?" Then he thought of a way, he asked Lin Meiyi: "Lin Meiyi, do you know Tian Tian's favorite songs?" Put it down and try it. ”

"Heli, try watching "Do You Hear?"

Hurry took his phone and tried to play the song:

"Wind, did you say something?

Heart, not quiet enough

I climbed to the top of the mountain

Close your eyes"

Tian Tian's eyelids began to move, it seems that this song has worked.

"Listen----- listen

I heard Baiyun ask me

Say, do you want to give up"

Tian Tian's eyes widened, she began to look around, and asked, "This... Where is this?" Heli said, "This is the hospital, hey! You were sick yesterday and the doctor said you had tuberculosis, but don't worry, you've been cured and the doctor said you can be discharged tomorrow. "Really? Great!" Tian Tian said happily.

"Heli, Hezhi!" Yang Fan ran to the ward with the newspaper and said, "You two come out for a while." He Li heard the order to Tian Tian: "That, Tian Tian, there is fruit on the bedside table, you eat it first."

"Heli, and Hezhi, look at it, things have spread all over Shanghai." Yang Fan took the newspaper and gave it to Hezhi, who asked, "Is it so serious?" It's already serious! The whole of Shanghai has canceled the subject of mathematics, hey! If we don't take action again, Suzhou will start to be infected', we have to hurry up!" Yang Fan said very sternly, and Hezhi asked, "That.... We don't know what to do. ”

Yang Fan said: "I have already thought of a way, in this way, there is a subway near this hospital, and when Tian Tian is discharged tomorrow, we will take Metro Line 1 and then transfer to Line 11, and take it to the end, it is Disneyland, and at the top of Disney Castle there, there is an accurate version of the map of the whole city of Shanghai." Then go to Yu Garden, where you can get the real "Nine Chapters of Arithmetic", you need to use the "Nine Chapters of Arithmetic" to calculate some binary equations and inequalities, so that the people over there will give you a key. Finally, go to the Shanghai World Financial Center in Lujiazui, reach the top, use the key to open the door, and you can get the plane coordinate axis inside, and then use the coordinate axis and the map of Shanghai to know the location of the hacker, and finally defeat him!"

"But what about the cost?" Hezhi asked

"Don't worry, I'm ready, I'll pay for the Disneyland tickets, subway tickets and financial center tickets this time."
