In the eighth year of Chongzhen's reign, Henan was in ruins. The father of a retired engineer and his son with a doctorate in history woke up and found that they had traveled to the troubled times of the late Ming Dynasty. Dad has a skill - building city walls, training troops, and doing engineering projects. Thirty years of military experience are all put to use. The son has brains - he can memorize all the affairs of the Chongzhen Dynasty and calculate every account of a whipping method. The phone battery is 87%, and the countdown begins. Li Zicheng was in trouble in Shaanxi, Huang Taiji was sharpening his sword outside the customs, and party strife was in full swing in the court. "Dad, there are still nine years until the end of the Ming Dynasty."
"Let's light the fire first." A pair of enemies, a father and a son, and a broken mobile phone, want to build a new world from scratch before the dynasty collapses. Easy farming + historical research + father and son, a story of survival in the late Ming Dynasty with laughter and tears.
