The environment of Nanling City is notoriously harsh.
Even within the city, it still feels like the sky outside is covered with a gray haze, never seeing sunlight.
Within the towering city walls, Bai Xiaotang, Lin Yuanyang, and You Le, each carrying 200 pounds of saplings, followed a group of Forest Guards, waiting to leave the city.
This was their training project for the day, to plant Purification Trees in the semi-Pollution Zone.
These Purification Trees are vegetation meticulously cultivated over decades by the research institute to purify the air in the Pollution Zone.
Each tree is valuable and requires proper planting and careful attention to achieve the purpose of purifying the air in the Pollution Zone.
Initially, the Forest Guards selling the saplings were worried that these outsiders might ruin their saplings, and followed them for several days.
Later, they found that their quality was high and they could meticulously meet planting requirements.
