You Were Supposed to Be a Fallen Kingdom's Crown Prince, So How Did You Build an Everlasting Golden Age?

After transmigrating as Zhu Cilang, crown prince of the Ming dynasty, the capital fell from the start, and his father hanged himself at Coal Hill! With rebel troops closing in, I was about to meet my end when I unexpectedly activated the Echoes of History System! [The compressed dried meat you invented was named Prince's Biscuits by future generations and displayed in the National Military Museum. National Fortune Points +100!] [The first batch of cement you fired laid the foundation for China's infrastructure-building prowess. It was featured in the future documentary Super Empire. National Fortune Points +1,000!] [Ding! You annihilated one hundred thousand Qing troops beneath Yangzhou, completely changing history. Future generations named an aircraft carrier battle group after you. National Fortune Points +100,000!] Traitors to the nation will be put on trial! Collaborators will be brought to justice! Corrupt scholars will be swept into the trash heap! When the Qing cavalry thought they could once again breach the frontier and invade the south, what they saw was an iron fleet blotting out the sky and ranks of riflemen standing in perfect formation. I, Zhu Cilang, changed the fate of this land of sun and moon with my own strength, leaving no regrets behind!
