The King of Ming Dynasty, Chongzhen recognized me as his elder brother

Travel to the Ming Dynasty.
It was the end of the Ming Dynasty.
Wang An, who did not have the system's golden finger, originally only wanted to make enough money to go overseas and live a peaceful life before the enemy attacked.
Unexpectedly, at the beginning, he mistakenly identified Zhu Youjian, the Prince of Xin who was about to ascend the throne, as his own cousin.
"My dear brother, you have been at the border for many years, so you may not know the current situation in the court. Prince Xin, who is about to ascend the throne, has been fooled by the Donglin Party. He even plans to kill Wei Zhongxian and disband the Jinyiwei! Isn't this a complete idiot?"
"Brother, the Little Ice Age is coming soon. The world is about to be in chaos. Come with me overseas! I will take you flying!"
"Brother, see this! This is the self-propelled musket I made! This is penicillin! This is cement..."
"My dear brother, we have many Han Chinese men in Nanyang, and rice can be harvested three times a year. When we get overseas, we can recruit soldiers and horses, expand our business, and create greater glory!"

The butterfly's wings fluttered gently, and a storm blew up in the Ming Dynasty!
