Tie Hongyan looked at it and found that the two circles on the front and back of the cake-shaped compound wheel are the same in most places except for the different colors. The only difference is that there is a very small light blue wavy pattern on the dark blue circle, while the light blue circle does not have very small dark blue wavy patterns...

"The two round surfaces are a little different." Tie Hongyan said.

"Where?" Ye Chi asked.

Tie Hongyan pointed to the light blue wave pattern on the dark blue round surface and said, "It's this."

"Wave pattern?" Yechi said, "You have noticed it, I didn't see it just now."

"It's normal not to see it." Tie Hongyan said, "The front and back of the complex wheel are blue, but one side is darker and the other side is lighter. The light blue wavy patterns on the dark blue round surface are not easy to be seen."

"But you found it!" Ye Chi said.

"According to it." Tie Hongyan said.

"Probably because you are the head of the gods." Nochi said, "You can find details."

"I feel that if you move this wave pattern, it may make the things sandwiched inside the side of the complex wheel stick out," said Tie Hongyan.

"Does it feel strong?" Yechi asked.

"Strong." Tie Hongyan said.

"After I heard you, this feeling was also very strong." Yechi said.

"What should I do?" Tie Hongyan said, "I'll try it with my nails."

When Tie Hongyan said that, he gently stroked the wavy pattern with his little fingernail.

Seeing that she didn't respond, she gently pressed down, and the wave pattern was not pressed down by her.

"No response." Tie Hongyan said, "Does the two of them need to do something together?"

Yechi said, "I'll try too."

"I want to try it with my fingertips now." Tie Hongyan said.

As she said that, she placed the little finger of her right hand on the wave pattern.

Her little fingers covered the wavy patterns. After picking them up, the wavy patterns turned half of them into dark blue.

"It's changed color." Tie Hongyan said, "Only half of it has changed color, the same as the surrounding color."

Yechi said, "Then I will put my fingertips on to see if my partner will change color."

"Come on." Tie Hongyan said.

Yechi immediately covered the wave pattern with the little finger of his right hand. When he picked up his finger, the other half of the wave pattern turned dark blue, the same color as the surrounding color.

Just after the wave pattern turned dark blue, it seemed to be gone and would not be seen on the dark blue side.

At the same time, a blue piece immediately stretched out from the side of the complex wheel.

"It just stretched out like this!" Ye Chi said. She was a little excited again.

"Yes." Tie Hongyan said, "Let's take it next to the door and see how to use it."

After Yechi agreed, the two of them walked towards the door, talking while walking.

"I remember where the picture came out just now." Tie Hongyan said, "It's just the crack in the door."

"I happened to think of it there too," said Yechi. "Is this blue film about to be stuffed into the cracks?"

"We think the same thing." Tie Hongyan said.

"Since that's the case, then just give it a try." Yechi said.

When the two arrived at the door, Tie Hongyan tried to insert the blue piece extending from the side of the double wheel into the crack of the door.

With a "click", the blue piece stuck in the crack of the door.

"Is that true?" Nochi smiled, "It seems to be going well this time."
