Three weeks after I signed an agreement with Duke Ashford, I brought the Helsa kingdom's royal army and attacked Bethoviel as planned. Everything was easy for us since Bethoviel was weakened by the attack from the Grirea Empire and we were also backed by the duke.
He supplied us with strong weapons and also skilled knights. Even when he came under the emperor of Bethoviel's order, he still helped us silently. As expected of him, someone who held military power in a big empire like Bethoviel.
With his help, Helsa managed to enter and took over a lot of villages and cities. That was something that I couldn't even think of before.
My uncle and I were actually aware that the duke actually only used Helsa to achieve his goal to make his nephew the next emperor. With the weapons and knights he sent us, he wanted Helsa to kill the emperor of Bethoviel. That way his son, Prince Roosevelt could raise the throne.
