Chapter 308: The rescue plane cannot arrive
Director Xiao called with hope.
"Hello."
"Yes, there is a volcanic eruption here now, and we need a helicopter to rescue."
"Yes."
"Okay, I'll wait for the call."
Xiao Wang said with a sad face: "Are you not going to save us?"
"What are you talking about? Why wouldn't the station send us soon? They said we need to apply and wait a little longer."
Chu Qiao didn't say a word, but silently took out the mutton to replenish his strength.
About an hour later, Director Xiao's phone rang.
"I got a call, it should be arranged."
Director Xiao happily turned on the hands-free mode.
There was no sound from the other side.
"Hello...can you hear me? Bad signal?"
"Yes, yes, Director Xiao."
"What's wrong? Is the sound wrong? Do we need to come later? It's okay, we can still hold on."
"Director Xiao, I'm sorry."
"What's the meaning?"
Chu Qiao whispered, "They probably won't be able to come."
Director Xiao's eyes widened. Xiao Wang and Huang Li, who were standing beside him, fell to the ground. "What? Are we doomed?"
"Why can't you come? These are four lives."
Director Xiao simply couldn't hear the other party's explanation.
"It's not their fault, actually. During violent volcanic activity, solid rocks and magma are broken down into fine particles, known as volcanic ash, under the effects of high temperature and high pressure. Large particles of volcanic ash settle to the surface, while volcanic ash with a diameter of less than 2mm can quickly reach an altitude of 10,000 meters and enter an airplane."
"It's nothing serious. It's just some small particles. Even with the heavy smog in Beijinzhou, we haven't seen many planes grounded."
Chu Qiao shook his head. Their understanding of volcanoes was too superficial.
"This is different from smog in nature. Volcanic ash can cause serious damage to aircraft."
"It can scratch aircraft parts. Volcanic ash contains a large amount of silica and a small amount of aluminum, iron, and magnesium oxides. Silica usually exists in the form of glassy silicates and is extremely hard. The sharp volcanic ash can scratch aircraft windshields, fuselages, engines, etc."
"And volcanic ash can cause aircraft engines to stall. The melting point of glassy silicate is around 1100 degrees Celsius, which is lower than the temperature of 1400 degrees Celsius inside the engine. Volcanic ash will melt inside the hot engine, and if it pushes against the turbine blades, it will cause the entire engine to stall."
"So scary?" Director Xiao frowned. In that case, forcing the plane to come would be even more unsafe.
"Director Xiao, not only that, but when volcanic ash comes into contact with water, it becomes highly conductive and could short-circuit the aircraft's internal circuits. The sulfuric acid droplets formed by the oxidation and hydration of silicon dioxide are corrosive and can damage engines and windshields. Therefore, once clouds and water droplets are present in the air, there will be danger."
[Oh my god, that's too dangerous.]
[No wonder Master Chu was certain the plane wouldn't come.]
[Wouldn't this trap Master Chu? ]
What should I do?
Director Xiao looked at Xiao Wang and Huang Li with shame: "I brought you here, I didn't expect..."
"Xiaoqiao, I'm sorry too."
Chu Qiao knew that it was hard for them to accept it, and it would be hard for anyone to accept it, but he couldn't continue to be so pessimistic.
"Don't be like this, Director Xiao. Just because they don't come to rescue us doesn't mean we have to die here."
"What do you mean? There's another hope?"
Director Xiao and the other two looked at Chu Qiao with longing in their eyes.
Chu Qiao has the most survival experience here, and everyone places their hopes on her.
"I don't have many options. The only way is to keep walking, find water and stay away from the volcano."
Xiao Wang's face turned grim: "How far is far?"
Chu Qiao shook his head. "That depends on whether the volcano continues to erupt. If it keeps erupting at this rate, we'll probably have to walk a long way, or stay here for ten days or half a month before a plane can come to pick us up."
"If the eruption ends quickly and no more ash enters the air, then we only need to go to areas where the ash has not spread and we can continue to contact domestic rescue."
There was black smoke billowing in the sky in the distance, which gave the impression of a bomb explosion. The level of pollution was almost the same as that of an explosion.
Chu Qiao stood up and said, "Let's go. If we don't leave now, the poison gas will spread and will attack us again."
When several people heard that it was poisonous, they immediately felt smoke rising from their throats: "Go, go, go, go now."
"Luckily, God is on our side. The wind is blowing from the north, so we're heading south."
Although this can avoid the poisonous gas, the speed of several people dropped significantly due to traveling against the wind.
"Would you like to eat?" Director Xiao took out some dry food.
Chu Qiao shook his head: "No, you guys should eat less too. These dry food will absorb water in the stomach and it will be difficult to excrete from the body."
[Master Chu's words sound very civilized.]
[High EQ: Food is difficult to excrete, low EQ: You will be constipated.]
【Master Chu is clever.】
【Little Chicken: That’s right, I just follow my husband.】
Chu Qiao rolled his eyes at the camera: "Chen Cong, have you studied that ancient corpse thoroughly? Didn't the ancient beauty come to you at night?"
Lu Zhan: Is there tea? Let them shout "tea" on the way, which will stimulate saliva secretion.
Chu Qiao's eyes lit up: "Director Xiao, do you have Pu'er tea?"
"Here, but what do you want Pu'er tea for?"
"Pu'er tea is a large-leaf tea with a very concentrated content of tea leaves and a strong function of promoting salivation. We can hold a small amount of Pu'er tea in our mouths, so that saliva will be secreted in our cheeks and tongue, which can help us last longer."
Director Xiao quickly took out his precious tea leaves: "I don't have much Pu'er tea with me, only three small bags left."
Chu Qiao carefully tore open the tea bag: "Let's use it sparingly."
As he spoke, Chu Qiao distributed a little bit of the leaves to each person. "Hold it in your mouth."
Everyone on the barrage began to question:
[Master Chu, don't listen to Dr. Lu's nonsense. Does the saliva produced by tea leaves come from the body?]
[That is, the wool comes from the sheep.]
[Looking at a plum to quench thirst, the same idea.]
Chu Qiao shook his head: "That's not the case. Although saliva secretion also comes from one's own fluids, it has a very good regulatory effect."
"Don't underestimate saliva. Common people call it 'spit', but in ancient times it was called 'golden fluid and jade liquid'. It is one of the important substances that maintain human life activities."
"I won't go into all the fancy functions, but I'll just mention two. One is that saliva contains many types of enzymes. The biscuits that Director Xiao and his friends eat are difficult to digest. After saliva is secreted, amylase and other enzymes can break down the starch in the food, reducing the burden on the stomach."
"It also has a protective effect. The mucin in saliva adheres to the surface of the oral mucosa to form a film that protects the tissue from dehydration. It also prevents irritants such as dust from entering the mucosa."
[Master Chu, why don’t you hold it?]
Chu Qiao opened her mouth and the camera shot towards her mouth, only to see Chu Qiao's tongue pressing against her palate.
"This is also a way to secrete saliva, but the tongue gets a little tired."
