Vlad made sure the defensive formation and troops in the Silent Wind Military Base were in top condition before leaving with Jormungandr, informing only his inner circle and General Anglius of this fact.
The rest of the Silent Wind Military Base believed that he and Jormungandr had entered deep seclusion to perform essential experiments. Part of that was correct, as a deep investigation was taking place by the A.I. Chip over the Vengeful Formation.
Vlad only allocated 50% of the A.I. Chip's full capacities to that task, so it would take over a month to thoroughly analyze and engrave the knowledge and muscle memory into his mind and body. However, that was fine since obtaining the Lightning Core and returning to the base would take much longer.
