Be a Kindergarten Principal in Pirates

<Pirates, invincibility, building a nation through science and technology, changing destiny, pseudo-system, changing the world> Alvin Gass, who was born in the world of pirates, found that the town was slaughtered by pirates when he came back from business. He awakened his overlord color between life and death, but his weak constitution made this power become his talisman. Alvin Gass, who was already determined to die, forced his Overlord Color to execute all the invading pirates. However, he also reached the end of his life. At this time, the <Famous Scene Sign-in System> came here with a 21st century soul to seize the body of Alvin Gass. But he didn't expect to be attacked by Overlord Color. In order to protect the weak souls who had traveled through time, the system had no choice but to face the impact of Overlord Color, so the powerful system was turned into a resentment species with abnormal data. As for the protagonist who traveled back in time, he adhered to the attitude of coming back, coupled with a big grudge system that can strengthen himself, and decided to change the fate of those characters, otherwise he would not have come in vain. Look at what kind of kid Garp is bringing? What does the Navy do? What happened to pirate technology? And what kind of troops did the Revolutionary Army have?
