City: I’ll start a sewage treatment plant

Mo Ling woke up and awakened the Purification Technology check-in system.

Every day, he would sign in for a purification technology!

He signed in for a sewage treatment plant at the start of the game!

What was that? My small factory purified a river on the first day?

What did you say? The purified river became the habitat of the endangered pufferfish?

It was even protected as an ecological zone?

The purified river water made the residents like to drink tap water?

Ah... I haven’t told you about this yet. I’ve actually planted a piece of wasteland and treated a lot of waste harmlessly.

It even purified the ocean and changed the saline-alkalized land.

In front of the purification system! What Godzilla? What five-headed shark, seven-headed shark!

That was impossible!
