Cai Yi looked left and right and directly looked for a big stone: "What else is the key, and I smashed it directly." ”

The "poof" stone smashed towards the lock, smashed it once but didn't break it, and smashed it three times without breaking it.

Qi Qian stopped: "Wait, don't smash it, the locks are all smashed, and they haven't been smashed yet, I'll take a look." ”

Holding the lock in the palm of his hand, looking at the crack of the lock, Qi Qian made a discovery and called Yu Luo: "Look at the inside of this lock." ”

Yu Luo took a closer look: "Isn't this just ......?" ”

Qi Qian: "Let's hurry down the mountain, Yu Luo and I should know where the key is, if nothing else, it will be in that place." ”

The three men and two women went down the hill as fast as they could, and there was no more wandering and chatter up the hill, and now they had to race against the clock, and the devil knew what would happen if they didn't leave at seven.

After going down the mountain, they returned to the roller coaster place of the playground, and just now Qi Qian looked at the shape inside the lock like a smiling face.

It was the same as the shape that Yu Luo had observed the rules of the roller coaster before using the decimal system and the coordinate axis, this thing must have been nearby, but they saw a smiling shape from the roller coaster, so they didn't look around the roller coaster again.

The program team also didn't expect Yu Luo to calculate it directly, and originally wanted the guests to find it out.

I couldn't find it after looking for a lap, and I couldn't find it after looking for a circle during the week of the roller coaster, but no one dared to ride the roller coaster at this time.

Ge Yun, who had been playing soy sauce, suddenly raised his hand and said, "Let me sit down." ”

This playground was so strange, and the fact that he was able to come back was so vague that it didn't feel real.

It always feels like someone behind it is planning and manipulating all this.

Ge Yun volunteered to ride a roller coaster, and when he came down, he said to everyone: "Are you looking for something with the same arc of a smile?" ”

Qi Qian and Yu Luo nodded.

"I just saw a place at the very top of the roller coaster that has that curvature, because it's dark now, and that place is glowing, and the glowing colors are connected together to be the smiling curvature.

"Somewhere."

Ge Yun: "It's too dark, I'm quite scared up there, I only know the general direction, but I don't know what's over there." ”

There are still ten minutes left.

Everyone followed Ge Yun's footsteps and hurried in that direction quickly, only to find that the place where the light was originally shining was a Ferris wheel, and at this moment the Ferris wheel had begun to run, some of the carriage lights were on, and some of the carriages were not open.

After searching for a lot, I finally found the key that looked like a smiley face in the carriage, and it took me a few minutes to run from the roller coaster to the Ferris wheel, and then another six or seven minutes to find it in each carriage.

There was still more than a minute left, and everyone was sweating profusely, and they all gathered around the side of the carriage, watching Yu Luo open the last lock.

"Click"

Open the treasure chest, which contains six swords.

Cai Yi: "What is this?" ”

Zeng Qin lit up: "Fluorescent sword, fluorescent sword that will shine at night." ”

Qi Qian: "It's only been a minute, let's each take a fluorescent sword and run towards the exit." I just came in through this entrance, and I'll show you the way when you run. There is also a sword Ge Yun, can you hold it for another person, you are strong in running. ”

Everyone starts running fast with a sword in hand, starting from the platform on the Ferris wheel.
