[Future] Mermaids are ferocious

Plant trees.

This is the only sustainable and long-term effective way.

But you must know that the living space of human beings has been compressed by the existence of alien beasts and alien plants. Now, once you step into the forest, there are eight mutations in ten trees.

The existence of mutated plants will attract the appearance of alien beasts or insects.

As a result, the living space of human beings is compressed again.

It's not that he doesn't want to plant trees.

He's just worried and scared.

Fear of them growing beyond human control.

Today, seventeen cities uniformly do not accept the existence of plants and pets, just to prevent them from mutating and destroying human living space.

After all, after the cataclysm, human beings have shrunk from hundreds of cities to [-] cities, and [-] cities disappeared not long ago.

The person in power unconsciously stroked the teacup in his hand.

Bad weather has affected their city.

The new walls... really work?

He pursed his lips.

Just as he was lost in thought, there was a knock on the door outside the office.

"Mayor Yun, here is a communication from Yang'an City."

It's his personal assistant.

This is a young woman with fair skin and beautiful appearance, with gentle and generous eyebrows and eyes, dressed in professional attire, intellectual and capable.

"According to the news report from Yang'an City, this time there has been a breakthrough in the materials of the spacecraft's power system."

She handed the document to Mayor Yun: "I have checked it, and the news is confirmed to be correct."

Mayor Yun was overjoyed when he heard the words.

He took the materials, looked down carefully, until his eyes fell on one of the items marked "the scales dropped by the king-level beasts", and his whole body tensed up again.

"The scales dropped by the king-level beast..."

This is more difficult than he imagined.

You know, the power system of the spacecraft has been deadlocked for ten years, and the nuclear energy system has been completed, but they have been stuck in the nuclear energy system.
