June 31, 4:00 on the ground floor of the Shanghai World Financial Center

Yang Fan took the key and a piece of snow-white paper, "Are you ready?" We're going up. ”

"Everything is ready to go.

"By the way, this piece of paper is the admission manual, let's take a look." Yang Fan opened the roll paper as he spoke, and read the text out.

"Admission Instructions

1. The coordinate axis is the center of the operation of the whole Shanghai, and it needs to be used carefully

2. If the detector cannot detect the coordinate axis, the whole Shanghai will be in danger of collapse

3. The coordinate axis contains 80% of the rational number molecules, which cannot be destroyed by irrational numbers!"

"Yang Fan, to be honest, I read this "Admission Instructions", and I feel that the difficulty of our expedition has increased again, you see the first one: 'The coordinate axis is the center of the operation of the whole Shanghai, and it needs to be used carefully!' If the coordinate axis is taken away, will Shanghai really collapse?" Hurley's voice began to tremble, and Hurry also felt a little suspenseful: "That's right, I asked the cashier just now, and it was true."

"Nope! Do you want to fix the matter? Even so, we're going to try! Rush over to it!" Yang Fan said and hid the rolling paper in his chemical white coat, and walked to the sightseeing hall, Hezhi and Heli looked at each other and shook their heads helplessly.

"It's fine! There aren't so many people in the financial center today. Hurley's heart began to calm down, and when he walked to the elevator entrance, there was black paint on all sides, and Hurley looked up at the ceiling again, "Oh my God! What is this?"

"Heli, don't make a fuss! It's an ED digital panel that can tell you the exact location of the elevator. Yang Fan looked at the ceiling and said calmly, "Now the elevator stops at a position of four hundred meters." ”

Saying that, Yang Fan pressed the elevator button, and the elevator quickly went down.

Walking into an elevator is like walking into a space capsule. During the elevator ascent, that feeling is like riding an airplane. The elevator quickly reached the 97th floor, and when I stepped out of the elevator, I was on the top of the 'bottle opener'.

"Looks like we're going up."

There was also an elevator directly in front of them, and after entering the elevator, Yang Fan found that there was a strange floor on this elevator - the 101st floor

"Strange? How can there be a 101st floor in a financial center?" Hurley was puzzled

Next to the button on the 101st floor, there was a keyhole, Yang Fan tried to press it a few times, but he couldn't press it, "It seems that this is the secret room where the coordinate axis is hidden." Yang Fan inserted the key and rotated it clockwise... The button on the 101st floor is lit!" Bang dang!" The elevator doors closed tightly, and the car was quickly pulled up.

101st floor

When I got out of the elevator, I found that this was not a room with hidden coordinates, but a lot of red lasers staggered and scattered, which didn't give He Li and Yang Fan much of a problem, but Hezhi couldn't! He Li and Yang Fan looked at Hezhi, who was wearing a huge long skirt, and if he wanted to pass through the infrared rays, he had to make the skirt shorter otherwise it would be easy to touch the red laser.

"Sister! Either you're here waiting for us. Hurley said.

"You stupid! Your sister is a math whiz! How could you not let her go?" Yang Fan said and looked at Hezhi blankly

"Don't worry, I have math magic." After saying that, she waved her hand, and the mathematical formula appeared around her skirt again, and suddenly! The light shined, and the skirt became shorter in an instant. This surprised Yang Fan.

"Let's go! Go find the axes. After saying that, Hurley walked towards the red laser.

One step, two steps, three steps

Just when they were about to succeed, Hezhi made a mistake, so that her skirt returned to its original state, the skirt touched the red laser, the laser disappeared at once, and the two walls slowly rushed towards them, they quickly ran to the end, and Yang Fan used another key to open the secret room.
