"Hey, Xiaoxiao, what's in you that's so heavy?" Cheng Nuo asked curiously.

"It's nothing, just some snacks." Su Xiaoxiao waved her little hand and said calmly, without any blush.

"snack?!"

Cheng Nuo opened her schoolbag and took a look. Whoa! It really has everything inside.

Potato chips, preserved fruit, shrimp crackers, melon seeds, pistachios, drinks...

The small schoolbag is full of snacks. What is left is sunscreen, sanitary napkins and other necessary items for girls to climb, but there is nothing. Almost all the space was given to the snacks that Su Xiaoxiao regarded as treasures.

The attributes of a foodie are fully exposed in Su Xiaoxiao.

"Hey, Cheng Nuo, just wait a moment."

Under the gaze of Cheng Nuo with black lines on his face, Su Xiaoxiao took out a generation of potato chips from the bag, unhurriedly tore open a hole, squinted his eyes and chewed happily.

"Cheng Nuo, do you want to eat?" Su Xiaoxiao looked up at Cheng Nuo.

"Uh, no need." Cheng Nuo stuffed the bag into his hiking bag speechlessly.

Cheng Nuo turned his head and smiled and said to Mu Leng who was standing with Su Xiaoxiao, "Mu Leng, give me your bag too."

"Huh?" Mu Leng was taken aback.

"I said, give me your bag." Cheng Nuo repeated, "I'm afraid you will be tired after climbing the mountain. I'll lighten your burden."

Mu Leng hesitated for a moment, then nodded and handed the bag to Cheng Nuo.

"OK, thanks."

It's not easy, it's not easy! Cheng Nuo burst into tears. Goddess Mu finally said "thank you" to herself. Cheng Nuo's mouth unconsciously grinned. It looks like a silly smile to others.

Cheng Nuo directly ignored Mu Leng's slightly weird gaze, and put Mu Leng's bag in the mountaineering bag graciously.

So far, the load of Cheng Nuo's backpack has reached 10.23 kg.

"Set off!!"

Under Jiang Qingqing's order, a group of thirteen people set off from the mountainside with an altitude of more than 400 meters. Goal, the peak of 1132.74 meters above sea level!

Of the seven boys, four walked at the front of the line and three walked at the end of the line. The six girls walked in the middle of the team, so that it was convenient for each other to take care of each other.

Cheng Nuo, Hao Shuai, and two other boys were at the front of the line.

Su Xiaoxiao held a bag of potato chips, and looked around curiously with her big bright eyes. Like most people, it was her first time climbing a mountain.

"Mu Leng, look at that cherry blossom is so beautiful!"

"Wow! There are peach blossoms here! It looks so beautiful!"

"That mountain is so high and magnificent!"

Su Xiaoxiao was like a lark, chirping non-stop.

Mu Leng was not bored either, he looked around with cold eyes, with a faint smile on his mouth.

Due to the physical strength of the girls, Cheng Nuo's four people who were leading the front did not dare to walk too fast.

"No, I'm exhausted, let's find a place to rest!" After climbing two to three hundred meters, everyone's excitement at the beginning passed away, but was replaced by a deep sense of fatigue.

The physical strength of the boys is not bad, it doesn't feel so obvious. But the girls are different, one after another shouting tired.

No way, everyone found a place to rest, drink some water, and eat something to replenish their condition.

The sun was high in the sky, and it was noon. The sun scorched the earth hotly, and the air was slightly distorted by the scorching.

Cheng Nuo found a rock and sat down, then stood up abruptly, rubbed his buttocks and cursed, "Fuck, it's so hot!"

Cheng Nuo took off the outer jacket and put it under his buttocks, so that he could not feel the slightest warmth from the chrysanthemum.

Cheng Nuo held a bottle of mineral water in one hand and chewed a piece of chocolate in the other.

Suddenly, Cheng Nuo caught a glimpse of a small figure and sat down beside him.

"Aw!"

The small figure jumped up with a whimper. , flexible like a rabbit.

"Why is it so hot..." Su Xiaoxiao was about to cry in pain. Cheng Nuo consciously moved his butt to the side to make room for Su Xiaoxiao.

Su Xiaoxiao sat on the jacket, pulled Cheng Nuo's hiking bag to her side, squinted her eyes and took out various snacks from the pink schoolbag.

"Cheng Nuo, do you want to eat?" Su Xiaoxiao asked again.

"No need. I have something to eat." Cheng Nuo smiled and shook his head.

After resting for about ten minutes, everyone continued on the road.

Soon, a group of thirteen people came to one of the famous scenic spots in Luoshan—the Glass Bridge. A bridge made entirely of glass. It is said that the glass bridge took two years and more than 100 million yuan to build.

"Wow! It's a glass bridge!"

"It's really a glass bridge. It's so beautiful. I wanted to see it before!"

Several girls let out a series of exclamations.

Cheng Nuo's gaze also swept across the glass bridge.

300 meters long, 2.64 meters wide, 723.24 meters above sea level, 6.58 centimeters thick, and a maximum weighing capacity of 1200 tons...

Although the glass bridge is called a glass bridge, it does not shatter when stepped on like glass. In fact, although the hardness of the glass bridge is not as good as that of the cement bridge, the hardness is definitely not small. Even if the entire 300-meter bridge is full of people, it will not collapse.

But... except in one case.

When Cheng Nuo saw the scene on the glass bridge clearly, his eyes suddenly froze.

Since it is the golden holiday of May Day, there are not a few climbers. But scattered on the entire Jushifeng at an altitude of more than 1,000 meters, there are few people.

At this time, walking on the glass bridge, except for two or three scattered tourists. There was another team.

There were twenty-four of them, all young girls in their twenties, wearing uniform clothes, standing in a row on the glass bridge of more than 300 meters.

A videographer stands in the front with a camera on his shoulders.

The group was led by a pretty young girl who yelled, "Three! Two! One! Go!"

The familiar magical music sounded, and twenty-four young girls danced on the glass bridge according to the same rhythm with the music. Waving your hands, tightening your belly, shaking your hips. The photographer also dutifully recorded all this.

These people from Class 18 were also enjoying watching by the bridge, but forgot to move forward for a while.

It's just that the data in Cheng Nuo's eyes is constantly changing.

The natural frequency of the glass bridge is...the movement frequency of one person is...the movement frequency of two persons is...the movement frequency of twenty-four persons is... (Note 1)

Groups of data are entered into Process Nuo's brain.

Cheng Nuo breathed a sigh of relief. Fortunately, the worst situation he imagined has not happened yet.

However, Cheng Nuo felt that it was necessary for him to remind them.

Because, once that kind of thing happens, the more than 20 people on the bridge will definitely die without a place to bury them.

At that time, there is no need to say anything Cmile Cmile, just change it to the grave head dance!
