In the pitch-black night, amidst the chaotic rain, a black figure moved swiftly through the barren mountains. Each time she appeared, large patches of ice would condense on the ground, supporting her at her feet. Whenever her figure disappeared, these large patches of ice would vanish as well.

Lin Ruo used her mental power to search for the location of the crystal core along the way. Although she was wearing rain boots, the mud under her feet had been completely softened by the acid rain and was very deep. If she stepped on it with force, her whole leg would easily sink into the mud. Although she wouldn't get hurt, it would still be quite troublesome.

The acid rain outside pelted against Lin Ruo's ice shield, which emitted wisps of cold air that froze the acid rain, causing the ice shield to grow thicker and thicker. Fortunately, it did not obstruct Lin Ruo's vision.

Some of these crystal nuclei were washed down the mountain by the rain, while others fell into the soil. The appearance of each crystal nuclei signifies the demise of a life.

Under Lin Ruo's mental scan, these crystal cores had nowhere to hide and were all cleaned and stored in her space.

Compared to the overall number of animals on the eastern mountain peak, the number of fallen crystal cores was not very large, only about 10%. The level of the crystal cores was also not very high, as the high-level mutated beasts were mostly hiding in the caves that Lin Ruo and his group had dug.

She collected all the crystal cores by teleporting around the mountain peak a few times.

Then she turned around and teleported towards the main peak, where there must be a lot of crystal cores.

Upon reaching the main peak, the situation was similar to that of the eastern peak. Lin Ruo scanned the area with his spiritual power and discovered that many mutated plants had survived on the main peak, but all that had survived were their root systems.

Lin Ruo shook her head slightly upon seeing this. After this acid rain, they should be grateful to have survived. After the acid rain comes the blizzard, and with only their roots remaining, they will probably go into a dormant state.

She cast aside her thoughts and began to scan her surroundings with her mental energy. Her figure moved rapidly, and each time she stepped on the ground, a thick layer of ice would form on that spot.

As she walked, she picked up crystals along the way. On the main peak, Lin Ruo didn't collect all the crystal cores she found. She only picked up some level 3 crystal cores and left the rest for the survivors on the main peak to exchange for supplies.

She collected crystal cores very quickly. In just half an hour, Lin Ruo had already covered the main peak and the western peak. Even if she only collected level 3 crystal cores, the number of crystal cores she collected was quite considerable.

Although she didn't pick up the other levels of crystal cores, she quickly scanned them with her mental energy and gained a general understanding of their quantity.

If it weren't for this acid rain, Lin Ruo wouldn't have known that there were so many mutated plants and animals on these two mountain peaks. This apocalypse has lasted for so long, it can only be said that the reproduction rate of these plants and animals is really fast.

After collecting the crystal cores, Lin Ruo quickly teleported back to her fortress. She didn't appear in the living room, but instead teleported directly to the second floor.

Because Afu and the other two were watching TV downstairs, she teleported away directly from the second-floor laboratory to avoid worrying them.

She removed the ice shield from her body, and the rain boots she had been wearing were melted back into a round black jade crystal and placed back into the still space.

She then walked to the chair in the sunroom on the second floor and sat down, immersing her mental energy into the space to take stock of the crystal cores she had obtained during this trip.

This time, there were more than 20,000 crystal cores. Most of them were found on her own mountain peak, while the remaining few thousand level 3 crystal cores were found on the main peak and the western peak. The fact that there were several thousand level 3 crystal cores shows just how many mutated plants and animals this acid rain killed.

Lin Ruo categorized all the crystal cores according to their level and placed them into the crystal core pile in the static space. He also threw some flesh and blood into the mutated plants in the space before leaving.

It's already 10 p.m. In two hours, this acid rain that has lasted for three days will be over, and then humanity will once again face a blizzard. She remembers that there was only a day between the blizzard and the end of the acid rain. Before people could recover from the terrifying acid rain, the blizzard had already arrived.

How many more people and animals will perish then? Lin Ru frowned as she looked out at the devastated world through the large glass window. She always felt that these natural disasters were like the world's way of filtering out humanity, but she didn't know when this filtering would end.

This acid rain alone killed about 60% of the mutated plants and animals. When the blizzard arrives, everything will be buried in it, and even movement will be restricted, making survival even more difficult.

When the blizzard hits, the weather will turn cold again, officially marking the end of the two-year period of extreme heat.

Although the temperature during a blizzard isn't as low as during extreme cold, it can still drop to -20 to -30 degrees Celsius. Because the temperature remains so low, the snowflakes don't melt at all when they fall to the ground, so they don't stick together and remain distinct. When the wind blows, the snow dust dances, and the sky is covered in white.

If a strong wind blows again, these frozen snowflakes are like thin blades, and people walking in the snow can easily be cut by them.

She recalled the blizzard scene from her past life, her eyes gradually darkening as she thought of the moment before her death in her previous life—the blizzard and the excruciating pain were truly unforgettable.

She pulled herself together, suppressing the images in her mind. She still had a lot to prepare, and with only one day left before the blizzard arrived, she had no time to wallow in sorrow.

She expanded her spatial domain, and in a flash, she appeared in her bedroom. She took out clothes that she had prepared beforehand and changed all the summer clothes in her wardrobe into winter cotton-padded coats and down jackets.

Lin Ruo didn't take out too many clothes. It was better to keep them in her space than to let them gather dust in the closet. She would take them out again when she washed them.

She then surveyed the entire fortress, taking all the appliances she wouldn't need during the blizzard, such as fans and air conditioners, back into her storage space.

She also covered the air conditioner in the house with a dust cover. When the air conditioner was installed, holes were specifically drilled in the wall. Now that the air conditioner is in the room, it's a bit of a hassle to fill in those holes. It's better to just put a dust cover on it so it won't get dirty.

She manipulated her water-based powers to create a thick film of water on the fireplaces in her home. Lin Ruo had also added cleaning fluid to the water film, which then washed and moved back and forth on the fireplaces.

Lin Ruo only condensed the water film again after cleaning it inside and out, and used spatial energy to send it directly into the acid rain outside. The dish soap was immediately corroded by the acid rain.

Lin Ruo's eyes lit up. Acid rain had such uses. It seemed she should make better use of it in the future.
