Humans had souls. Without souls, he was a walking corpse, a dead man! An Army also had a soul, and the soul of an Army was called the soul of an Army. An Army with the soul of an Army would be invincible! A country should have its own soul. If a country had its soul, then the country would slowly become stronger. A nation should also have a soul. Once a nation had a soul, it would become invincible.
Although the people in the sword spirit world were already disciples of the sea exploration sect, he could not say that he had given his soul to the sea exploration sect. The sea exploration sect did not have his soul yet.
A person's soul was born, but the soul of an Army, a country, or a nation was formed after birth. The formation process of this soul might be very long. After experiencing all kinds of hardships, it would slowly form its own soul.
