Yucheng's air quality was still 58, but once they entered Qinglin Villa, it dropped straight to 28—a decrease of 30.
Minister Jin was in charge of air purification and treatment, so he knew just how astonishing those numbers were.
He was all the more eager to see what Minister Lu had mentioned, but the other man remained tight-lipped, leaving him quite helpless.
"This is nothing yet, Minister Jin. Let me take you over to Qinglin Manor." Minister Lu smiled and headed toward Qinglin Manor.
Before long, Minister Lu had led Minister Jin into the manor.
As soon as Minister Jin entered, he instinctively picked up his AQI monitor and took another reading.
A refreshingly clean breeze swept over him, impossible to describe. It felt as if every pore on his body were greedily breathing in the air.
A number appeared on the display, leaving him stunned.
3!
The AQI was actually only 3?
It was almost unbelievable.
Minister Jin was certain that no city in the country—not even any human settlement—had air quality like this.
"Shocked, Minister Jin?" Minister Lu teased. "There's something even more shocking. Come on!"
With that, Minister Lu led Minister Jin to a plot of transplanted Purifying Grass.
Minister Jin noticed the plants. "Minister Lu, why are all these grasses bent over? Did the transplanting go wrong?"
Minister Lu smiled. "Don't worry about whether they're bent. Take another reading here."
Minister Jin nodded and turned on the monitor again.
The next moment, an even more astonishing number appeared: 1.
"This..." Minister Jin could hardly believe what he was seeing.
Minister Lu asked again, "Surprised? It reads 1 because that's the lowest value the monitor can detect. Otherwise, the number would be even lower."
That was true.
The lowest value on commonly used AQI monitors was 1.
