A ball of black dots blocked the bright moonlight, and the ball of black dots quickly expanded and began to disperse everywhere. A black dot began to shine, dragging out a long tail. Then dozens of black dots turned into glowing brooms and hit the ground at the same time.

In the night sky of Yutai County, a huge fireball carried an ever-increasing light to cut through the atmosphere. The fireball became bigger and bigger, and the light became more and more dazzling. Finally, a light that was hundreds of times brighter than the sun flashed by, followed by a loud bang that shook the sky and the earth. The fireball exploded. The huge shock wave instantly destroyed the jungle dozens of kilometers and those buildings exposed in the open and flat ground. A fragile peak of Hutou Mountain was flattened halfway.

After the large shock wave, there were overwhelming winds and flames. The intensity of the wind exceeded 12 levels, and the temperature of the flames reached nearly a thousand degrees. A boar that escaped the shock wave was burned to ashes in less than three seconds, and the ashes were blown away by the strong wind, leaving no powder left. The small lake water in the lake was evaporated instantly, and all the creatures in the lake were gone. The ashes were swept into the air, and fragments continued to fall in the air. The entire earth turned into a fire hell.

In a winding and deep cave in Hutou Mountain’s giant stone valley, Lin Zaishan pulled Li Yan out of the hot pool water. Lin Zaishan took a deep breath and felt that the air in the cave seemed to be boiled, with a pungent smell. He opened the backpack behind him and took the exit mask to put it on himself and Li Yan. He took out the thermometer and prepared to measure the air temperature, but found that the thermometer had exploded. He hurriedly signaled Li Yan not to leave the water surface. He shone the road with his headlight and dragged Li Yan with one hand to continue swimming deep into the cave. The more he went in, the water temperature and air temperature seemed to be closer to normal. Finally, the two stopped in front of a huge stone wall.

"Can you go ashore? I'm afraid of such a dark cave in the water." Li Yan said.

"Go up."

The two crawled out of the water and couldn't help feeling exhausted.

"It was really too dangerous just now!" Lin Zaishan sighed. It turned out that before the meteorite explosion, Master Lin proposed a survival strategy: "water absorption cave." Lin Zaishan immediately woke up and threw Li Yan into the car. He drove to the Giant Rock Valley at full speed in 4 minutes, and then entered the water absorption cave in 5 minutes. When the explosion occurred, they had already entered the depths of the cave. The chain reaction caused by the explosion threw them into the pool, which also allowed them to escape the disaster of high-temperature barbecue.

"It's really thanks to Master Lin!" Lin Zaishan said.

"It's really thanks to you," said Li Yan.

"If I remember correctly, there seems to be a romantic story between us that needs to continue." Lin Zaishan smiled.

"Go to you!" Li Yan said: "We are still alive and dead. Can you guarantee that there will be no new explosions, the temperature of the cave will not rise again? Or will the cave not collapse and bury us alive?"

"My beauty, can you shut up the crow's mouth?"

"Is they talking about objective facts?"

"Where did your romantic mood go?"

The two of them had to stop after mixing for a while because they had already discovered that the air was too thin, and even through the mask, they could feel the floating impurities. The dust became thicker and thicker, and the smell became worse and worse.

"Will we run out of oxygen and suffocate to death?" Li Yan asked effortlessly.

"..." Lin Zaishan was speechless.

"I really wish I was a fish now," Li Yan continued.

"Why?"

"Because fish can breathe in the water."

"I seem to remember something." Lin Zaishan said in a flash of inspiration.

"What did you remember?" Li Yan asked with difficulty by putting her mouth in front of Lin Zaishan.

"Give me a little encouragement with your romance, maybe I can think of any way to improve our current situation."

"Okay, think about it quickly, otherwise I will die and no one will be romantic with you in the end of the world." Li Yan kissed Shan gently on the cheek.

"Ah, there is!" Lin Zaishan said happily: "I remember when I came to this cave before, I found that there were not only fish and other animals in the pool, but also a very lush aquatic plant. This aquatic plant secretes bubbles at a speed visible to the naked eye. At that time, I specially collected and analyzed these bubbles, which were serious oxygen." (Author's note: This aquatic plant was created by the author for the plot, so readers should not believe it.)

"So what? We are not fish, and we still can't absorb it."

Lin Zaishan said, "Who said he couldn't?" He took out several disposable plastic garbage bags from his backpack and dived into the water. After a while, he squeezed the garbage bags that were bulging by the air and floated up. He took a sucking breath into the garbage bag and said, "It's great!"

"Come on me too." Li Yan took the garbage bag, took off her mask and sucked it hard. The airflow entered her lungs, which quickly brought an unprecedented feeling of relief. "I never thought that a bag of air would be so precious!"

"This collection efficiency is a bit low and will increase my oxygen consumption," said Lin Zaishan.

"Don't you have an infusion tube or something? Can you connect it with the bag?" Li Yan suggested.

"My beauty, you are such a genius!" Lin Zaishan jumped up with joy. He immediately started to assemble it. In a short while, the two automatic oxygen collection devices were arranged. Lin Zaishan respectfully handed it to Li Yan with a tube and said, "My beauty, please enjoy it."

Li Yan took the tube, took a deep breath, and imitated the tone of the Queen Mother of Chao and said, "No, I have a lot of rewards!"

The days when they have oxygen to suck seem to be getting elated all of a sudden. Lin Zaishan brought a lot of compressed biscuits and pure water in his backpack, so the two of them didn't have to worry about their diet. They just didn't know how long they would be trapped in the cave, and they had to plan for a long time to eliminate waste. In addition, they had bad appetites and little supply consumption. The cave was pitch black, and both of them could only use headlights or flashlights. Although they brought a lot of replacement dry batteries and the rechargeable batteries were in full state, in order to save power, Lin Zaishan turned off the headlights when they were resting; while Li Yan was afraid of the darkness and turned on the flashlight from time to time.

The day after the meteorite landed, 12:30.

"It's noon now, why is it still so dark?" Li Yan asked.

"Maybe the dust covers the sun. I'll go out and check it out."

Lin Zaishan turned on the headlight and slowly touched the outside of the cave. After turning a corner, he obviously felt that the air temperature suddenly rose, and the air became more and more irritating and smelling. He insisted on moving forward, the temperature was getting higher and higher, as if he was being roasted in a fire. He jumped into the water, and the water in the pool was boiling hot. Lin Zaishan did not dare to grop forward any more, and turned around to swim back.

"How is it outside?" Li Yan asked with concern.

"I can't even get out of the cave, it's too hot there! We can only stay here honestly."

Li Yan coughed and said, "The air seems to be getting more and more pungent."

Lin Zaishan handed her a bottle of pure water and said, "It should be better to drink some water."

After drinking water, Li Yan stopped coughing and turned around and walked aside.

"What are you doing? Don't run around!"

"I'm going to do it, don't follow me."

The day after the meteorite landed, at 16:15 pm, Li Yan's cough became more and more severe, and Lin Zaishan also started to cough. The two kept drinking water and inhaling oxygen, but it could only relieve it for a moment.

"I have a headache." Li Yan said weakly.

"You should take another oxygen immediately."

Li Yan took a heavy breath and said, "It's a little better, but it still hurts."

Lin Zaishan rubbed her temples, pinched Hegu, and asked, "Do you feel better?"

Li Yan shines the flashlight on his concerned face, feeling much better without realizing it, and says, "I'm much better. Cough... Yes, why do you look... Cough... in good condition?"

Lin Zaishan smiled and said, "Will I be in a bad state with you, just with a beautiful woman by my side?"

"Are you as long as there is a beauty by your side, cough... your condition will be better?"

"Not necessarily." Lin Zaishan said: "At least it must be a beautiful woman with good personal character and temperament."

"If I stay in this cave for a few more days, my temperamental beauty will definitely become an ugly woman with pneumothus breasts. Can you still maintain your condition?"

"Don't worry, you won't become ugly."

At 22:20 pm, Li Yan coughed again, as if she was about to cough out her lungs. Lin Zaishan was also coughing constantly.

"I can't stand it anymore!" Li Yan said: "I want to... cough... cough... die!"

"Don't talk nonsense, cough..., hold on for a while... cough... well."

"You have... cough... there..." Li Yan seemed to struggle to say something.

“What’s there?”

"Is there any... cough... there's a... cough... girlfriend?"

Lin Zaishan was surprised that she would ask this question, and immediately the appearance of her ex-girlfriend Bai Feifei appeared in front of her. She felt ache in her heart and said with a wry smile: "I am a poor loser, how can a girl be willing to follow me?"

"You are a...cough...a very good man, who doesn't like you...cough...she doesn't know how to appreciate it."

"Who is your boyfriend? He must be great, right?" Lin Zaishan asked back.

"My boyfriend is... cough... my camera. That day, he actually... coughed... after I fell down the hillside, I ignored me!" Li Yan coughed again.

Lin Zaishan hurriedly massaged her back, and when she calmed down, she handed over pure water.

"I'm... cough... regretting and glad." Li Yan looked at Lin Zaishan and said, "I regret not... cough... not following you after I met you a year ago; I'm glad that I'm glad that I'm with you when the end of the world is coming."

"Don't think so much, cough, live your current life well, okay?"

"good."

The two of them looked at each other and both gained a moment of tranquility from their intense coughing.

On the third day after the meteorite landed, both of them fell into an almost endless cough. Li Yan obviously had hallucinations due to lack of oxygen.

"Dad, are you here to save me?" Li Yan said to Lin Zaishan.

"So wake up!" Lin Zaishan put the oxygen inhalation tube into Li Yan's mouth.

A few minutes later, Li Yan coughed again, but she became a little more awake.

"Did you see my... cough... mom and dad?" Li Yan asked.

"They will be lucky and auspicious. You... cough... don't worry."

"I feel very uncomfortable. Cough... I have a request, Cough... Can you promise me?"

"you say."

"Please cough... kill me. I don't want to suffer anymore!"

Lin Zaishan's heart sank, and he shouted, "Please cheer up, don't think too much, you will get better!"

"If you die, don't have to cough... you will suffer..." Li Yan said indifferently.

"What should I do if you die? Do you want me to face the end of the world alone?"

"You... are you alone?" Li Yan woke up a little more.

"Yes, you're going to die, I'm the only one left. Who will keep me in the best condition?"

"But I cough...my condition is no... hope."

"Who said there is no hope? As long as your heart is there, hope is there!"

Lin Zaishan took a deep breath of oxygen and his brain began to run at high speed. When he encountered difficulties, he liked to ask "Master Lin", but since the meteorite landed, his phone could not be turned on. Now he can only rely on his own wisdom to find a way to deal with difficulties. Scenes flashed through his mind.
