At least so far, the warriors Zong Shen has interacted with were either not recruited willingly or were in a near-death state; there hasn't been any mention of someone being sealed after death.
However, there are still some questions involved in this.
Wenresa was summoned from an ancient Rare Level Natural Altar.
The price was a Complete Purple Soul.
Yet using the Recruitment Scroll comes almost with no cost.
Besides, this time, billions of Lords have descended.
Before the Lords have a large population and a stable source of Training Books.
The Recruitment Scroll became the only way to obtain warriors.
As for obtaining warriors from the Indigenous People, the timing is not yet mature.
Even if each of the billions of Lords has on average a dozen farmers and eight or nine warriors.
The total would reach the scale of hundreds of billions.
