When Si Bo, a doctor of chemistry, opened his eyes, he traveled through time and became a rotten gambler in Yuzhou during the Qi Dynasty - his family lost all his money, his child bride Su Jin was about to be sold to pay off her debts, and she still had blunt injuries on the back of her head from a gangster. In a desperate situation, he caught a glimpse of the distillation device left behind in the dyehouse in the corner of the house. Using modern chemical knowledge as an edge, he took orchid grass to condense incense and made mint dew. He earned his first pot of gold with his "magic incense", protected Su Jin, and gave the refugees a job.
He recruited Chen Hu, a brave hunter, as his guard, befriended Liu Chengye, a merchant from the south of the Yangtze River, and gathered bamboo craftsmen and refugees to build an incense shop. However, he came across the heinous crimes of the eunuch Cheng Ken, who secretly sold military supplies to the enemy in the Northern Liao Dynasty, forcibly demolished people's houses to build private houses, and regarded the people as ants. In order to protect the people around him, Si Bo was forced to go to Beijing, used spices to identify perjury, and used technology to break the trap, and finally let Cheng Ken die under the rocks of the refugees.
However, the imperial court remained corrupt and the Northern Liao Dynasty still committed crimes. The refugees knelt down and begged him to "establish himself as king." Si Bo originally just wanted to survive, but he was pushed by the world to shoulder heavy responsibilities: defending Yuzhou, fighting against the Northern Liao Dynasty, conquering the south of the Yangtze River, and pacifying the princes. From a "pilgrim" who made a living by spices, to the founding emperor of the Jing Dynasty who gathered the hearts of the world.
He always remembered the half piece of moldy cake that Su Jin handed over the night when he first cooked Ningxiang. When the nine states were finally unified, the people shouted not "Long live", but "Master Sifang, you have food to eat!" The so-called pilgrims in the world were never the incense sellers, but ordinary people who yearned for peace and were willing to follow him to protect the people and bring peace to the world.
