"Shh..."

The sound of rain continued from outside, accompanied by a sizzling corrosion sound, white smoke rose, and as the raindrops fell on the ground, visible pits immediately appeared.

As if by magic, the plants in the distance that Lin Ruo hadn't taken into his space kept twisting and swaying. Even as they shrank rapidly into the ground, they were still disappearing little by little in the rain.

Immediately following, a series of mournful howls echoed through the rain, from the mutated animals that hadn't yet found a place to hide.

Seeing this scene, Afu and the other two couldn't help but take a few steps back. Their big eyes looked at the scene outside with some fear. Lin Ruo had described the dangers of acid rain to them before, but seeing it with their own eyes, they realized how terrible it really was.

Not only did they retreat themselves, but they also pulled Lin Ruo, who was still standing at the fortress entrance, back by her clothes, as if afraid that the raindrops would hit her and hurt her.

Seeing that the three of them were a little nervous, Lin Ruo did not resist. She was dragged to the center of the fortress living room by their strength. After they calmed down a bit, she scratched their chins.

"Go watch TV for a while. I've prepared some new cartoons for you today that you haven't seen before."

Afu and the other two turned to look at the front door again, hesitating. Lin Ruo shook her head to indicate that she wouldn't go out, and they were relieved. They nuzzled Lin Ruo's body before walking towards the living room.

Lin Ruo stood inside the fortress, looking out at the rain through the glass window. A strong, pungent smell gradually filled the entire fortress.

These stimuli made her eyes sting a little; sometimes, having an overly sensitive sense of smell isn't necessarily a good thing.

She frowned slightly, and with a thought, she closed the fortress gate completely, shutting out the smells entirely.

Then she extended her mental energy outwards to check the situation on the mountain peaks. Through her powerful mental energy, Lin Ruo saw that the mutated plants on the mountain peaks that she hadn't been able to store in her space had been corroded and had lost all their branches and leaves. As the acid rain intensified, the ground branches of these mutated plants withered rapidly, and there was no more wood-elemental energy inside. Then, their withered bodies were corroded with a large number of fine holes, and finally, like melted chocolate, they softened into the soil at an extremely fast speed and disappeared completely.

Of course, these are just the branches on the ground; their roots have already penetrated deep into the ground and are even constantly wriggling downwards.

They know that the soil they once depended on for survival will soon turn into a weapon that can kill them. Only by constantly extending their roots downwards and avoiding the soil contaminated by acid rain can they preserve their last hope.

Acid rain continued to fall from the sky, and the rain was very heavy. In just half an hour, puddles of all sizes appeared on the ground. The soil around the puddles was being rapidly eroded, and the ground of the entire mountain was slowly sinking.

The mental energy continued to expand outward, sweeping over many mutated animals that had not participated in the migration. These animals had seen Alu leading the mutated beasts to migrate, but had not followed. Although they also sensed a strong sense of crisis, they did not know where the crisis was hiding.

Many of them originally hid under the branches and leaves of those mutated plants, treating the acid rain as ordinary rainwater, but now they have all fallen into this rainwater.

They were unaware that the rainwater had such a strong corrosive effect. By the time they realized it, it was too late. They were surrounded by acid rain, with dense rain everywhere. No matter where they fled, they were subjected to continuous and intense pain. They howled pitifully and fled in panic, but soon collapsed on the ground and could no longer get up.

Their enormous bodies were covered with burn marks, and their flesh and blood were rapidly "flowing" away under the saturation of the rain, seeping into the soil beneath them. In just a few minutes, a giant mutated beast, several meters in size, completely disappeared in the acid rain, leaving only a shining crystal core on the ground. This shows just how fast the acid rain corroded them!

Many animals also choose to find a solid shelter, such as a cave or under a boulder. In such an environment, these mutated plants and animals seem to have reached a consensus. They no longer attack each other, but instead rely on each other for warmth.

Without cover, they will use their large claws to quickly scratch the mountainside, and soon a small hole big enough to accommodate them will be scratched out. However, such a place cannot stop the rain. With the help of a light breeze, the rain does not fall vertically. The raindrops hit the rock wall, and the rock wall will slowly erode inward.

However, once these mutated animals enter the shelter, they will continue to dig deeper if they find that the mountain in front of them is being eroded. As long as they gain the upper hand at the beginning, they still have a chance to survive.

Inside the three huge burrows that were dug out, the mutated animals could smell the pungent odor outside through the ventilation openings. They could hear the wailing of the mutated animals outside, which were being corroded by acid rain. They were shivering and huddled together.

Seeing that a considerable number of the mutated plants and animals on his mountain had been preserved, Lin Ruo withdrew his spiritual power. The high temperature outside had dropped considerably due to the arrival of acid rain. Inside, there was a huge ice basin that Lin Ruo had just condensed, and an air conditioner fan was blowing directly at the ice basin, spreading cool air throughout the fortress, making it very refreshing.

Turning around, I saw three furry dogs lying in the living room, their eyes fixed on the TV, seemingly oblivious to the acid rain outside.

In their eyes, the fortress was incredibly sturdy, impervious even to crystal cannons, let alone the heavy rain outside. As long as their master closed the fortress gates, they would be completely safe.

Moreover, their owner is with them. As long as she is there, they will not be in any danger even without this fortress. This is their confidence in their owner's strength.

As the acid rain fell, Lin Ruo felt a sense of relief. After the acid rain came the blizzard, and the weather would turn cold again. The things she had taken down during the extreme cold were still stored in her space, and she was going to take them all out and clean them.

"The three of you must not open the gate. The acid rain outside is terrible. You will only be safe inside the fortress."

Lin Ruo stroked the three fluffy heads of her dogs and gave them instructions. Although she had started describing what the acid rain would be like to them when she asked them to dig burrows two days ago, she couldn't help but give them the instructions again at this moment.

After receiving nods of response from the three of them, Lin Ruo turned and went upstairs to the laboratory. Instead of rushing to read books or study medicines, she first focused her mental energy into the space to see how the mutated plants she had stored there were doing.
