It wasn't about just having a one-time deal and being done with it. He wanted to show her sincerity and tempt her into dealing with him more in the future.
He was someone with a good eye when it came to investments, and dealing with this lady would bring him profits. Not just profits, but another layer to protect his family in the future.
Tapiwa was unaware of Paul's thoughts, as all she could think about was how all that was hers.
Honestly, when she saw all these weapons, the first thing she thought was that she would be choosing. Or he would at least give her weapons on one wall, or possibly half of them.
But to think that he was actually giving her everything, she was happy. These weapons were enough to mean so many soldiers. She could see her army growing stronger and facing the enemy head-on when the time came.
Tapiwa started inspecting the weapons, and Paul had mainly found her guns, autocannons, bombs, fire throwers, and military daggers.
