The Fire Lizard Battle Group, after upgrading their Single Soldier Armor, had combat power that was not inferior to that of a Wizard.
In fact, compared to many Wizards who had never participated in a Plane War or had only fought in one or two, these Fire Lizard soldiers were even superior.
So, Richard did not plan on keeping them in the Secret Realm forever.
The Green Forest World was vast, and it would take more than a hundred or so Three Rings Black Wizards several decades to scout it completely.
This was under the condition of devoted searching. If the Wizards were to fight, study something, or encounter intersections in the search areas during this time,
the duration would more than double.
By dispatching the Fire Lizard Army, Richard aimed to expand his search range and increase the likelihood of finding World Tree Subbodies.
One person's power is ultimately limited.
