  Lin Xiajin was about to get out of the car but Xiao Ruo pushed her on the car~ He said: "You come directly and I will go down and change."

Xiao Ruo.opened the door and walked around. At this moment, Lin Xiajin had already changed to the passenger seat.

  Lin Xiajin saw that Xiao Ruo's hair had been soaked by the rain. She picked up a tissue and subconsciously wanted to wipe it , but it fell in mid-air and stopped again.

  "Your hair is wet." Lin Xiajin said in a deep voice, suppressing the restlessness in her heart.

  It can't be said that this slightly wet hair actually has a different kind of abstinence in him.

  "Yeah." Xiao Ruo responded.

  Both of them seemed to have forgotten the brief collision just now... it was light and cold.

  Lin Xiajin shook her head, what was she thinking!

 She is pregnant now, but the key is that she doesn't know who the baby's father is yet...

  She's afraid there will never be an answer to this.

  Lin Xiajin turned to look out the window to divert her attention...

  What Lin Xiajin didn't know was that Xiao Ruo was watching her struggle with the corner of his eye that she couldn't see, and the corners of his mouth slowly raised...

  It rained and the road collapsed, so they had to take a longer detour, which would require us to pass through the villages in City B.

  "There's nothing we can do about it. It seems like the rain won't stop for a while." Zhang Yuan said, looking at the rain getting tighter outside.

  "Hey..." Xin Li also sighed, and she felt a little cold.

  "This rain is not normal." Zhu Jingjing kept staring out the window and said with a frown.

  "...Why is it abnormal? Isn't it normal now that it's the rainy season?" Wang Han asked without thinking.

  "Yes! But do you think it has rained since the end of the world? And the smell of this rain is wrong."

  Zhu Jingjing opened the window, stretched out her hand to catch two raindrops, and smelled it again.

  "You smell it, is it a bit acidic? This means that its hydrogen ion level is increased (low pH). It may be harmful to plants and aquatic animals..."

Acid rain is caused by the emission of sulfur dioxide and Nitrogen oxides, which react with water molecules in the atmosphere to produce acids.

  "Acid rain not only adversely affects forests, freshwater and soil, but can also kill insects and aquatic life. "

 " It can also cause paint to peel off, corrosion of steel structures such as bridges, and weathering of stone buildings and statues. "

  '..." Wang Han's head was pounding after hearing this.

  Finally, he concluded: "Is this acid rain harmful?"

 ' Yes! If it rains for a short time, the impact will be small, but if it rains for a long time, the harm will be greater. "

 ' Acid rain can also pollute water resources and cause harm to the human body, and it can even affect the human respiratory system. "

  "The sulfur dioxide and nitrogen dioxide in acid rain can cause asthma, dry cough, headache, and diseases of the eyes, nose, throat, etc.! "

  Zhu Jingjing usually talks little, is timid and has almost no sense of presence, but now she talks so much.

  Wang Han has a completely new understanding of Zhu Jingjing...

  As expected, the one wearing glasses is a top student...

  "It's best to wear a mask when we go out, and if you don't have one, it's better to put a piece of cloth around it. "Zhu Jingjing said.

  Wang Han responded, immediately picked up the walkie-talkie, and briefly told Xiao Ruo and Zhang Yuan what Zhu Jingjing said.

Lin Xiajin was sitting in the car, and when she heard Wang Han's words, her whole face looked bad. She's not in the mood for the light rain outside.

  She's afraid the plants that have been exposed to rain may not grow well.
