Five days had passed since the Advance Team returned to the camp. Due to Luo'er's injuries, the entire team was not dispatched again but remained in the camp. Actually, Li Si had no intention of investing too many personnel in this mission anyway. They just needed to develop the preventive medicine and implement related epidemic prevention work.
The rest, including reducing the epidemic area and eradicating the monsters, were tasks for the Church Court and the armies of the relevant countries to complete. This was a massive project, and even if Li Si wanted to help, he couldn't contribute much.
Therefore, he let Luo'er's team stay behind, ready to face any emergencies. As for the needs of the research department, they were mainly handled by the Murong Squad, which also served to train their team.
