Civilization Guardian Legion, 21st Detachment.
Commander Zhang Sai, mid-Fifth Tier. He commanded 30,000 personnel, including ten early-Fifth Tier, 800 Fourth Tier, 5,000 Third Tier, with the rest all Second Tier powerhouses.
Lin Yu's guard unit.
A total of 100 people. Aside from one captain and two vice-captains at the Fifth Tier, the remaining ninety-seven were all peak Fourth Tier.

The real challenge lay ahead.

Given enough time, they could indeed do it.
But the problem was that they did not have that time. If they failed to destroy the target within the time
