Stocking up in space: surviving in a world of crisis

"But why do I feel that Sister Ye Fu is looking at you with murderous intent?" After Luo Yang finished speaking, he met Jiang Rong's faint gaze. The back of his neck felt cold, and he rode away quickly, fearing that he would be assassinated by Jiang Rong after a few seconds. .

Entering the territory of Ning Province, Ye Fu took out the temperature measuring instrument and took a look. It was 13°C, a bit cold, but it was bearable, but the road was too difficult to walk, and the ground was full of rocks. At a glance, the mountains and plains were desolate.

Ye Fu put the binoculars into her bag, and when she saw Han Feng catching up, she waved to Han Feng, "Captain Han, at this speed, we will have to walk for at least five days to reach our destination. What's the name of that place?"

"Moshanling is at the southernmost tip of Ning Province, at the junction of Lan Province." Han Feng paused for a moment, then continued, "Doctor Ye, before we came back, my teammates and I went to count the number of wild boars and bison. Thousands, because the magic mountain is very big, after the ecology has slowly recovered in the past few years, the animals have multiplied rapidly, and the number has increased. I want to know, how can we bring back so many wild boars and bison?"

"Is there any good solution for Captain Han?"

"We tried to drive them away, but wild boars and bison are difficult to tame. Wild boars can bite people. They have tusks and are very ferocious. Driving them away may not work. We have no choice but to divide them into two groups. One group stays and guards." Watching wild boars and bison to prevent them from migrating away, I took other team members back to the base and reported this to the base chief. They are all cliffs, even if the base flies over, they cannot land."

Ye Fu nodded, "The water celery also grows in the magic mountain?"

"There used to be a river in Moshanling, which ran through the two provinces and flowed from Ning Province to Lan Province. Now the river has turned into a swamp, and the entire swamp is covered with cress. At that time, we were not sure whether this plant could be eaten. My teammates said it looks like celery and should be edible, we fed some to the wild boar, and the wild boar didn’t die, so we were sure it was cress.”

They are now located in the northeast of Ning Province. Unless they take a shortcut, the total distance must be more than [-] kilometers.

"The road here is difficult to walk, and there are thousands of acres of dry mountains ahead. The terrain of Ning Province is complicated and divided into three plates. The mountains are in the south, and the central part is a dry area. The terrain is high in the south and low in the north, descending in a trapezoidal shape. The province has a temperate continental arid and semi-arid climate."

At this time, Luo Yang and Jiang Rong also caught up. After many years of natural disasters, almost no grass grew in the north and central parts. Han Feng was worried that the horses might suffer in the next few days. He proposed to cut some grain and grass here. There are few small streams, so there is no need to worry about drinking water.

"There is no need to worry about this. We have prepared enough food and grass." Besides, the grass on the side of the road grows sparsely. The grass was exposed to the high temperature a while ago, and the grass was all wilted. It is estimated that the horses would not eat the grass.

"You guys are really well prepared." Han Feng was ashamed. Before he set off, he never thought that this trip would be so easy.

Two hours later, the four of them rode into the dry mountain. At this time, the fog had completely dispersed. Looking at the rolling dry mountain and large expanses of black soil in the distance, they finally understood why Han Feng was worried that the horse would not be able to eat grass.

"I remember that the soil in Ning Province is loess, how did it turn into black soil?" Luo Yang squinted his eyes, trying to see more clearly.

"Has there been acid rain here?" Ye Fu asked suddenly.

"We also had this suspicion, so when we went back, we brought some soil back to the base. After research, the researchers at the base confirmed that the soil had been corroded by acid rain, and it had been corroded many times."

"You mean, there have been many acid rains here?"

Han Feng nodded, "Yes."

After entering the dry mountain, everyone slowed down. The soil on the ground was scorched black by the acid rain. The ground was very hard, like solidified cement. There were puddles of water in the shallow depressions. The soil could not absorb the water, and the rainwater remained like this. down.

Ye Fu let out a cry, and then tightened the reins to stop the horse. After dismounting, Ye Fu took off his gloves and soaked a little rainwater with his fingertips.

"How could this be?" Everyone was surprised to see that the rain had become sticky.

"This rainwater is the same as aloe vera juice. It is not only viscous, but also has a moss-like smell. It may be caused by the soil. The soil corroded by acid rain will release microorganisms that can degrade rainwater. No wonder I was in Malaysia just now. When I look at the rainwater in these shallow depressions from my back, I always feel that there is a layer of oil floating on it."

Ye Fu took out a plastic bottle from his backpack and poured some rainwater. Han Feng and Luo Yang looked at her in puzzlement.

"Sister Ye Fu, what are you doing with this water?"

"I'm a little interested, let's go, leave the dry mountain first, the air here smells bad, if you smell it too much, you may feel dizzy."

There are still some corroded branches and stumps on the ground. The branches have been integrated with the soil, and the stumps have been corroded and weathered. If you pinch them lightly, the trees will be broken into flour. Who would have thought that this place used to be a forest.

There are relatively small grasslands and deserts in the north of Ningxia Province. Because it borders Mongolia Province, the geographical environment in the north is no different from that of Mongolia Province. After walking out of the dry mountains, it is a desert. For decades, the state sent people to plant in this desert. There were quite a few poplar trees, but Han Feng told them that when they passed through the poplar forest, there were only large areas of yellow sand left except for the dead trees.

"Thousands of acres of land have been destroyed. It is estimated that in another 100 years, there will be no grass growing on this land. The power of acid rain is too great."

Ye Fushen agreed, "The main reason is that there have been a lot of acid rain here. Judging by the degree of corrosion and hardness of the soil, it is estimated that it will last for a month every time. Even if the wind blows the sand from a distance, it will not help, and the potatoes will become dead. Soil, unless two meters of raw soil is placed on top of the eroded soil."

Because of natural disasters, the usable land is getting smaller and smaller. Because of the spread of nuclear leakage in northern Xinjiang, everyone can only migrate to Mongolia. After the sea water floods the south, it is estimated that there is no land. Moreover, there are many nuclear power plants in the south, which may have fallen. See Looking at the large expanses of black soil, everyone felt a little heavy.

"You said before that there are thousands of acres of dry mountains here. I thought the mountains were covered with dead trees. I didn't expect that there were no trees in the dry mountains." Luo Yang felt a little emotional.

"I don't know what year and month it will be before the old scenery can be restored here."

Ye Fu stretched out his hand and made a forward gesture, "As long as the blue star is here, 100 years, 200 years, 500 years... One day, the earth will heal itself, nature will be full of vitality again, and so will we humans .”

Under the dark clouds and on the black soil, four people and four horses galloped against the wind with the sound of horses' hoofs, and finally walked out of the dry mountain.
