After Ling Chen was released from prison, he abided by his master Xuan Chenzi's last wish and embarked on the road of seeking justice for his master with a mysterious IOU. He teamed up with his arrogant junior sister Su Wan, and used the IOU as a guide to subdue the jade carving master Zhao Tianlei with their wits. They planned to outwit the private jet and successfully regained the master's property "Yishengtang". During the process, the shocking secrets of the murder of the master and apprentice and the destruction of the sect gradually came to light. Ling Chen relied on his hidden strength, extraordinary resourcefulness and compliant technological means to dismantle the enemy's conspiracy layer by layer, liquidate past blood debts in accordance with the law and regulations, adhere to the bottom line of justice, rectify the name of the sect with fair and just rules, and open a new chapter in his life.
