"Those who achieve great merit in this battle can earn a Spirit Vein or exchange it for other rewards!"
Since there's no way to forcibly keep the Loose Cultivators, they can only be tempted with benefits.
And for some small families and small Sects of Loose Cultivators, having a Spirit Vein is what they've pursued their whole lives!
Because with a Spirit Vein, they have a foundation, no longer drifting like duckweed. They can grow and prosper, rather than being heavily restricted as they are now, finding it hard to grow stronger, only to weaken over time until they completely vanish.
Many Loose Cultivators heard this and gritted their teeth. In the end, they chose to stay!
At most, they would lose their lives, but if they could obtain a Spirit Vein, their families, Sects, the future generations, and Disciples would have a better environment to develop and a foundation to become stronger.
