Blue-Tiled Roofs and Red Walls over the Land

Wang Pengling, a top student at Tsinghua University's Academy of Arts in the modern era, brings his scientific logic, artistic craftsmanship, and historical foresight with him when his soul transmigrates into the body of Wang Jixian's prematurely deceased second son in the forty-fifth year of the Great Qian dynasty. This happens in an unopened courtyard of the Wang family estate. Outwardly calm, aloof, and decisive, he is inwardly devoted to his loved ones and home, with a hidden passion for his country. Armed with knowledge from another world, he plunges into the turbulent currents of a feudal dynasty.

Upon arriving at the ancient estate, he uses modern hygiene knowledge to break a supposedly inauspicious curse. He establishes himself through papermaking innovations and commercial planning, thwarts the clan's greedy designs, wins over his envious cousin Wang Jiesheng, and stands up for his sister Wang Jinyao, who refuses an arranged marriage. Before long, he is at the helm of the Wang family's business empire.

After leaving Guangfeng, he befriends the governor of Jiangyou and invests deeply in the porcelain industry of the porcelain capital. He improves glazes with chemistry and creates innovative designs, building the renowned Jixian Porcelain Works, only to anger Zhang Tingyu, a corrupt powerbroker at court, and become entangled in a dark web of collusion between officials and merchants. When he seeks guidance from Celestial Master Zhang, he awakens to the ambition of "saving the nation through industry." He secretly lays his plans, allies with loyal officials, studies Western knowledge, and trains local militias, preparing for the foreign invasion to come.

On the eve of the Opium War, he stands at the forefront of the times with modern industries, improved firearms, and elite militia troops. He deals a heavy blow to the Lion Army in the Humen Sea Campaign, quells a coup in the capital, and helps Jia Qin reform the government's abuses, forcefully changing the dynasty's course of decline. Once the land is at peace and industry has made the nation strong, this man from another world who once stirred up the times retreats to Tongbo Mountain with his dearest family and friends. All he leaves behind is the sight of gray tiles and red walls beneath a clear sky, while his legend of perseverance, reform, and devotion to country shines through the annals of history.
