Qin Feng, a prodigal son from outside the Pass, returned to Daqing and became the sixth prince. He guarded northern Liaoning and used sporadic modern knowledge to build Guang'an City into a paradise on earth - coal fire warmed the city walls, iron horses stepped on the ice and frost, asphalt roads led to thoroughfares, and the ground was warm to melt winter snow. King Qing visited incognito and saw the prosperity under his rule. He was secretly shocked that he had no intention of turning back, which made him even more passionate. Donating food and stoves during snow disasters, donating masks during epidemics, suppressing rebellions and ending wars, and expelling aristocratic families from the cold famine. King Qing wanted to give him the country as a gift, but he used Marxism-Leninism to break the monarchy. He smiled and said his lifelong wish: "I just hope that the people will have no worries and have leisure every day to walk around freely."
