"In addition to the discharge of waste from factories, there are other ways to cause acid rain. If modern humans want to deliberately create acid rain, it is not difficult. The city center is where the army has appeared. You must know the history of human wars.

, in addition to gunpowder and cannons, there are also horrific biological and chemical weapons."

He began to save water. There was plenty of food, but the water resources could not be replenished. The villa area was on a high ground and groundwater could not be dug. To get water, he had to wait for rain or go to the foot of the mountain.

There are still heads of people standing tall and zombies walking everywhere.

"Acid rain usually occurs because the concentration of sulfur and nitrogen compounds in the atmosphere is too high, mainly sulfur dioxide and nitrogen oxides. Except for extreme situations such as volcanic eruptions, it is basically human activities that cause acid rain, which accounts for the largest proportion.

The factor is that the factory burns waste and emits waste.”

"What I mean is that the conditions that create acid rain in urban centers are not regular factory waste emissions."

Looking into Tang Xue's peaceful eyes, Jing Yuan gradually calmed down and sighed.

But looking at the tide of zombies surging outside the wall, he sighed again and asked himself, is there really a land in this world where people can live peacefully?

But ghosts are ethereal and insubstantial, and there is no way to talk to them. Jingyuan sometimes even wonders if it is his illusion, but various visions indicate that Zhoushan City is undergoing earth-shaking changes.

"Maybe they have found a way to deal with mold, and maybe we can ask them for help."

"I don't deny these possibilities, but six years ago, the army abandoned the entire city of Zhoushan and evacuated. When they left, they did not send an announcement on the radio station or say they would rescue survivors. They were in the midst of a disaster.

People turned a blind eye. There was a radio placed in the public area of ​​the survivor gathering place. People stayed there every day to debug the radio, but they never received any signal. In fact, they did not give us hope and rescue.

The supplies piled on the beach are more like they were dropped than left behind. The government has been destroyed. We don’t know what the people driving the fighter jet and the forces behind it want to do."

Jingyuan was silent for a moment and said: "You are right. I am too anxious, but don't you want to return to normal human society?"

"Society is made up of connections between people, and the society I know has been completely destroyed." Tang Xue looked into Jingyuan's eyes: "I mean, I just want to talk to

at your side."
