"Wow, Xiaoxiao, what's inside you? It's so heavy?" Cheng Nuo asked curiously.

"It's nothing, just some snacks." Su Xiaoxiao waved her hands and said calmly, without a slight blushing.

"snack?!"

Cheng Nuo opened his schoolbag and saw it. Wow! There was really everything inside.

Potato chips, dried fruits, shrimp sticks, melon seeds, pistachios, drinks...

The small schoolbag was filled with snacks. The remaining items such as sunscreen and sanitary napkins were not available for girls climbing. Almost all the space was given to snacks that Su Xiaoxiao regarded as treasures.

The foodie's attributes are fully exposed to Su Xiaoxiao.

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

Under Cheng Nuo's gaze, Su Xiaoxiao took out a generation of potato chips from the bag, tear it opens a hole without any haste, squints his eyes and chews happily.

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

"Uh, no need." Cheng Nuo put his bag in his mountaineering 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."

"Hmm?" Mu Leng was stunned for a moment.

"I said, give me your bag." Cheng Nuo repeated, "I'm afraid you will be very tired after climbing a mountain in a while, so I'll reduce some of the burden on you."

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

"Okay, thank you."

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 opened. To others, it seemed like a silly smile.

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

At this point, Cheng Nuo's backpack has a weight of 10.23 kg.

"Set off!!"

At the command of Jiang Qingqing, a group of thirteen people set off from the mountainside with an altitude of more than 400 meters. The target is the peak at an altitude of 1132.74 meters!

Seven boys, four people walked at the front of the team, three people walked at the end of the team. Six girls walked in the middle of the team, so that they could take care of each other.

Cheng Nuo and Hao Shuai, and two other boys, are at the forefront of the team.

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

"Mu Leng, look at the cherry blossoms so beautiful!"

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

“That peak is so high and spectacular!”

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

Mu Leng was not tired of it either. His cold eyes looked around and there was a faint smile on his lips.

Due to the fact that the girl's physical strength was taken by the front, Cheng Nuo's four people who were leading the way did not dare to walk too fast.

"No, I'm so tired. Let's find a place to rest!" After climbing for two or three hundred meters, everyone's initial excitement was over, but instead was replaced by a deep feeling of fatigue.

The boys have good physical strength and they don’t feel that obvious. But the girls are different, and they shout that they are tired one after another.

There was no way, so everyone found a place to rest, drink some water, and eat something to replenish their condition.

The sun hangs high in the sky, it is noon. The sun is blazing with the ground, and the air is burning and twisted.

Cheng Nuo found a rock to sit down, then stood up suddenly, rubbed his butt and scolded, "Fuck, so hot!"

Cheng Nuo took off a layer of windbreaker outside and put it under his butt, so he couldn't feel the slightest enthusiasm coming from the anus.

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

Suddenly, Cheng Nuo caught a glimpse of a small figure touching him and sitting down.

"Ao!"

The small figure jumped up suddenly, as flexible as a rabbit.

"Why is it so hot..." Su Xiaoxiao was almost crying in pain. Cheng Nuo consciously moved his butt to the side and gave Su Xiaoxiao a place.

Su Xiaoxiao sat on her shoulder jacket, pulled Cheng Nuo's mountaineering bag to her side, and squinted her eyes and took out all kinds of snacks from her pink schoolbag.

"Cheng Nuo, do you eat it?" 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 to set off.

Soon, a group of thirteen people came to one of the famous attractions in Luoshan, Glass Bridge, a bridge made of glass. It is said that this glass bridge took a total of two years and cost more than 100 million yuan to be built.

"Wow! It's a glass bridge!"

"It's really a glass bridge, so beautiful. I've wanted to come and have a look before!"

Several girls exclaimed repeatedly.

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

300 meters long, 2.64 meters wide, 723.24 meters above sea level, 6.58 cm thick, and a maximum load-bearing capacity of 1,200 tons...

Although glass bridges are called glass bridges, they do not break like glass. In fact, although the hardness of glass bridges is not as hard as cement bridges, they are definitely not small. Even if the entire 300-meter bridge is full of people, they will not collapse.

But...except in one case.

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

Because it is the golden holiday of May Day, there are many climbers. However, people appear sparse at an altitude of more than 1,000 meters across the entire giant rock peak.

At this time, walking on the glass bridge, there were another group of people besides the two or three tourists scattered.

There were 24 of them, all of whom were young girls in their twenties, wearing uniform clothes and standing in a row on a glass bridge over 300 meters.

A videographer is standing in front with a camera on his back.

The leader was a young and beautiful girl, who shouted loudly, "Three! Two! One! Start!"

The familiar magical music sounded, and twenty-four young girls jumped on the glass bridge at the same rhythm as the music, waved their hands, closed their abdomen, and shook their hips. The photographer also dutifully recorded all this.

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

But Cheng Nuo's data is constantly changing.

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

A group of data input processes in Nuo's brain.

Cheng Nuo let out a light breath, but fortunately, the worst situation he had imagined had not happened yet.

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

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

By then, there is no need to say anything about C, just change it to a grave dance!
