Chapter 51: Tomb head

　　 "Oh, Xiaoxiao, what's in you so heavy?" Cheng Nuo asked curiously.
　　 "It's nothing, just some snacks." Su Xiaoxiao waved her hand and said calmly, without blushing.
　　 "Snacks?!"
　　 Cheng Nuo opened his schoolbag and took a look. Huh! It really has everything inside.
　　 Potato chips, preserved fruit, shrimp crackers, melon seeds, pistachios, drinks...
　　 The little schoolbag is full of snacks. The rest are like sunscreen, sanitary napkins and other necessary items for girls to climb, but there is none. Almost all the space was given to snacks that Su Xiaoxiao regarded as precious.
　　 The attributes of food-eating are fully exposed in Su Xiaoxiao.
　　 "Hey, Cheng Nuo, wait a moment."
　　 Under Cheng Nuo's black-line gaze, Su Xiaoxiao took out the first generation potato chips from the bag, tore open an opening, squinted and chewed.
　　 "Cheng Nuo, do you want to eat?" Su Xiaoxiao looked up at Cheng Nuo.
　　 "Uh, no need." Cheng Nuo silently stuffed the bag into his mountaineering bag.
　　 Cheng Nuo turned his head and smiled and said to Mu Leng who was standing next to 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 for a while. I will relieve you of some burdens."
　　 Mu Leng hesitated, nodded and handed the bag to Cheng Nuo.
"OK, thanks."
　　 is not easy, not easy! Cheng Nuo burst into tears. Goddess Mu finally said "thank you" to herself. The corners of Cheng Nuo's mouth opened unconsciously. It looked like a silly smile to others.
　　 Cheng Nuo directly ignored Mu Leng's slightly weird gaze, and graciously put Mu Leng's bag in the mountaineering bag.
　　 So far, Cheng Nuo's backpack has reached 10.23 kilograms.
"set off!!"
　　 At the order of Jiang Qingqing, a group of 13 people set off from the mountainside more than 400 meters above sea level. The goal, the peak of 1,132.74 meters above sea level!
　　 There are seven boys, four of whom are walking at the front of the team, and three are walking at the back of the team. Six girls walked in the middle of the team so that it was convenient to take care of each other before.
　　 Cheng Nuo and Hao Shuai, as well as two other boys, are at the front of the team.
　　 Su Xiaoxiao was holding a bag of potato chips, and his big bright eyes looked around curiously. Like most people, she has come to climb a mountain for the first time.
　　 "Mu Leng, look at the cherry blossoms so beautiful!"
　　 "Wow! There are peach blossoms here! It looks so beautiful!"
　　 "That mountain is so high and spectacular!"
　　Su Xiaoxiao is like a lark, chatting non-stop.
　　 Mu Leng was not bored either, his cold eyes looked around, with a faint smile on his mouth.
　　 Due to the physical strength of the girls, the four of Cheng Nuo who led the front did not dare to walk too fast.
　　 "No, I'm exhausted, let's find a place to rest!" After climbing two or three hundred meters, everyone's initial excitement passed away, but was replaced by a deep sense of fatigue.
　　 The physical strength of the boys is pretty good, it doesn't feel so obvious. But the girls are different, one by one shouting tired.
　　 No way, everyone found a place to rest, drink saliva, eat something to supplement the state.
　　 The sun hangs high in the sky, it is noon. The sun burned the earth hotly, and the air was burnt a little distorted.
　　 Cheng Nuo found a rock and sat down, then stood up abruptly, rubbed his and cursed, "Fuck, it's so hot!"
　　 Cheng Nuo took off the outer jacket and placed it under his buttocks, only to feel the slightest warmth from the chrysanthemum.
　　 Cheng Nuo holds a bottle of mineral water in one hand, and chews with a piece of chocolate in the other.
　　 Suddenly, Cheng Nuo caught a glimpse of a small figure and touched him to sit down.
　　 "Wow!"
　　 The small figure jumped up. , Flexible like a rabbit.
　　 "Why is it so hot..." Su Xiaoxiao was immediately crying in pain. Cheng Nuo consciously moved his to the side, giving Su Xiaoxiao a place.
　　Su Xiaoxiao sat on the jacket, pulled Cheng Nuo's hiking bag to his side, squinted his eyes and took out various snacks from the pink school bag.
　　 "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 13 people came to one of the famous attractions in Luoshan-the Glass Bridge. A bridge made entirely of glass. It is said that this glass bridge took a total of two years and spent more than 100 million yuan to build it.
　　 "Wow! It's a glass bridge!"
　　 "It's really a glass bridge, it's so beautiful, I wanted to see it before!"
　　 Several girls exclaimed again and again.
　　 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 cm thick, and a maximum weighing capacity of 1200 tons...
　　 Although glass bridges are called glass bridges, they are not broken like glass. In fact, although the hardness of glass bridges is not as good as that of cement bridges, 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, his eyes suddenly condensed.
　　Because of the May Day Golden Holiday, there are not a few mountain climbers. But scattered over the entire Giant Rock Peak at an altitude of more than 1,000 meters, UU reading www.uukanshu.com seems to be rare.
　　 At this time, walking on the glass bridge, except for the scattered two or three tourists. There is another team.
　　 There are 24 of them, all young girls around 20 years old, wearing uniform clothes, standing in a row on a glass bridge of more than 300 meters.
　　 A cameraman stands in the front with the camera on his back.
　　 The leader is a beautiful young girl, she shouted, "Three! Two! One! Start!"
　　C mile C mile zilezilealerg~~
　　 Mary Mary milemilepemaidan~~
　　 The familiar magical music sounded, and twenty-four young girls danced on the glass bridge in the same rhythm with the music. Wave your hands, tuck your abdomen, shake your hips. The photographer also dutifully recorded all this.
　　 These few people from Class 18 were also watching the bridge with gusto, but for a moment they forgot to move forward.
　　 is only Cheng Nuo, the data in his eyes is constantly changing.
　　 The natural frequency of the glass bridge is……The frequency of movement of one person is……The frequency of movement of two persons is……The frequency of movement of twenty-four persons is……(Note 1)
　　 A group of data is input into the brain of Cheng Nuo.
　　 Cheng Nuo let out a soft breath. Fortunately, the worst situation he imagined has not happened yet.
　　 However, Cheng Nuo felt it necessary to remind them.
　　Because, once that happens, these two dozen people on the bridge will definitely die without a place to be buried.
　　 At that time, there is no need to say C miles C miles, just change it to Tombtou Bengdi!
