Along the Wujiang River, the lives of the poor are the lowest. On the third day of Shen Ke's time travel, his father died in Wuyan while escorting the boat. The government said it was a natural disaster, and the Meng family said his father had embezzled it. To live, you have to pay taxes, to pay taxes you have to repay debts, and to pay debts you have to go to the dock to carry your life. A lame watchman picked him up and taught him to hide and sharpen his knife secretly at night. From then on, he had a black iron billet knife in his heart. Every drop of sweat made the knife sharper. Others relied on their strength to get ahead, but he relied on tolerance to get ahead; while others grabbed opportunities, he stayed behind the seventy-two water tanks, taking into account the entire world's accounts. Everyone laughed at him because he could only carry water in his life. It wasn't until one day that they discovered that the most inconspicuous water boy on the Wujiang River was holding half a tide command that could open the fog eyes, and the bones under his feet were all the bones of the Meng family's shipwreck. On March 3rd, foggy eyes opened. Shen Ke is not in a hurry. After half a lifetime of sharpening the knife, someone must be the first to see the blood.
