The protagonist Yang Zhanfeng went out to get drunk due to family reasons. He didn't want to encounter a meteor falling from the sky when he returned home. After his death, he was reborn in the parallel world of Dayan Kingdom for seven years. The protagonist is reborn in the body of Yang Zhanhua, the fourth son of the Yang family, the four major families of the Dayan Kingdom. He is seventeen years old this year. He has been a playboy since he was a child. Since he does not have to inherit the family business, he has been eating, drinking and having fun since he was a child. When he became an adult, he even volunteered to go to Yunnan to manage several shops there. Because Yunnan only has a few small shops, and because Yunnan is adjacent to a barbarian country called Wannan, criminals often come in to rob the country, so the eldest son quickly agreed to Yang Zhanhua's request and sent him to Yunnan as the family manager. When Yang Zhanhua arrived in Yunnan, the system awakened. This is a system for the rise of a great power. As long as the system has points, you can return to the original world, but you can only use the black account because the original owner has died! Moreover, the points can be exchanged for any supplies in the system, including the little boy, but the points are too long to be used! Points can also be exchanged for silver coins, which can then be exchanged for any supplies before the end of the world war. Yang Zhanhua used the double-crossing function to buy low and sell high. He took modern handicrafts back to Dayan to deceive foreign devils, and took gold from Dayan back to modern times to exchange for silver and other handicrafts in various countries and regions. Once you have money, you can redeem points, and the points can be redeemed for weapons and materials in the system. In the end, the protagonist stood on the bridge of the world's largest aircraft carrier, staring at the vast ocean, and just said: Let's go! The entire fleet has more than ten aircraft carriers, more than one hundred capital ships, and a large number of auxiliary ships sailing to the other side of the ocean!
