Ever since All Beings Base was founded, Lin Qiao hardly took soldiers from Base Number One out of the base to perform tasks. Lin Feng sometimes took them out to collect supplies, but most of the human soldiers were still being trained in the base. The force of Base Number One was small in numbers, so the base didn't even need to prepare a training ground for them. They found a clearing area right near Base Number One and turned that into their training ground.
The army in Base Number One had merely about three-thousand people, and a small part of them died during the second explosion of the virus. Later on, the number reached about five-thousand after a few rounds of recruitment. Currently, most of them were still new and needed training.
