While the world leaders were debating, the Polar Bear Emperor finally spoke. His expression was serious as he said, "We cannot explain the cause of all this, but we must face this disaster together. Whether it's the Dragon Kingdom or any other country, we all need to unite and find a solution together."

His words were like a refreshing breeze, gradually easing the atmosphere in the meeting room. The world leaders nodded in agreement, realizing that only through unity could they overcome the current crisis.

Japan is a tranquil island nation situated in the middle of the ocean. However, recently, this island nation and the world have been plagued by a series of terrible natural disasters, the most worrying of which are the initial, highly corrosive acid rain and the widely reported tsunami.

The Prime Minister of Japan, named Yuji Matsumoto, is a young and capable leader. He has always been vigilant about natural disasters and has carefully studied various coping strategies. However, the recent frequency and power of acid rain and tsunamis have exceeded his expectations, causing him extreme anxiety.

On the first day of acid rain, Prime Minister Yong-ji convened a meeting of his cabinet members to discuss how to deal with these natural disasters. The atmosphere in the meeting room was tense and somber. The Prime Minister sat at the head of the table, his gaze serious and resolute, revealing his inner anxiety.

"Gentlemen, we must take immediate action, or our island nation will face a great catastrophe!" Prime Minister Yuji's voice was loud and resolute. His words sent a chill down the spines of those present.

"Your Excellency, we have managed to increase the warning systems for acid rain and tsunamis, but the frequency and power of these natural disasters remain unpredictable," a cabinet member raised the question.

"Yes, I understand. But we cannot stand idly by. We must find more ways to protect our island nation." The Prime Minister's voice was filled with determination.

The atmosphere in the meeting room became tense, with everyone struggling to cope with the out-of-control situation. The sky outside was overcast, as if acid rain would fall at any moment.

"Your Excellency, I have an idea." Suddenly, a young assistant stood up.

The Prime Minister's eyes were fixed on him, awaiting his advice.

"We could consider building a giant defensive structure to protect against acid rain and tsunamis."

In this way, our island nation can be protected more effectively. "Although the assistant's voice was young, his thinking was very mature."

Prime Minister Yong-ji pondered for a moment, then nodded in agreement.

"Okay, we'll begin planning this defense facility immediately. We need to find the best engineers and experts to participate in this project." The Prime Minister's voice was full of hope.

Over the next few days, the Prime Minister of Fusang and his team held continuous meetings with engineers and experts to discuss how to construct this massive defensive facility. Their goal was to minimize the impact of acid rain and tsunamis, protecting the island nation's safety.

As the meeting continued, the sky outside had completely darkened, and acid rain poured down like bursting poison, its power growing stronger with each passing moment. People looked out the windows in fear and unease, as if the world was about to be completely corroded away.

However, under Prime Minister Yong-ji's leadership, the people were not consumed by fear. On the contrary, they were even more convinced that as long as they worked hard, they would be able to overcome this disaster.

Giant defensive structures rose up on the island of Fusang. All the people of Fusang thought they could easily withstand all natural disasters, but they would be dealt a devastating blow in the future, especially by various mutated creatures in the sea.

When the first acid rain struck, the defensive structure demonstrated its immense power. Like an insurmountable barrier, it kept the acid rain at bay. The people of Fusang rejoiced at this sight, finally feeling a sense of relief.

However, the threat of a tsunami remains. Prime Minister Yongji and his team understand that their work is not over.

"We need to find a way to withstand tsunamis; that's our next task," Prime Minister Yong-ji said firmly and forcefully.

They began researching and testing various tsunami mitigation methods in hopes of finding the most suitable solution.

Countries around the world have also urgently activated various life-saving measures to protect their people.
