The Second Book of Whispering Molan

"Yongle Dadian" has been lost for hundreds of years. The world only knows that it is a unique book. No one has noticed that the secret files of Chinese science and technology that span thousands of years are hidden in the pages. Chen Fan accidentally inherited the identity of the guardian of the code and unlocked the secret map in the ceremony. Only then did he realize that from the pre-Qin Dynasty to the Song and Yuan Dynasties, the core crafts, systems and cultural archives of the past dynasties were sealed in more than ten underground vaults across the country. From the origin of the system in Guanzhong to the pinnacle of craftsmanship in Heluo, from the grand scene of the Silk Road in Dunhuang to the wonders of handicrafts in Jiangnan, every library is a dusty museum of ancient science and technology. Following the clues in the classics, Chen Fan led the team on the road to break through and protect the classics: cracking the arithmetic mechanism to unlock the pre-Qin arithmetic scripture, restoring the iron smelting process to open the Han Dynasty craftsman hall, piecing together the fragments of the Silk Road to restore the full picture of commerce, and deciphering the secret waterway to recover the Song and Yuan nautical charts. The secret color porcelain formula, the structure of the jacquard machine, the evolution of movable type printing, and the construction of ancient astronomical instruments that have been lost for thousands of years have been revealed one by one, completing the missing key puzzle pieces in the history of Chinese science and technology. The road to protecting the code involves perseverance and sacrifice, and there are great victories and defeats. From the desert Dunhuang to the misty Jiangnan, a journey to protect civilization spanning thousands of years is slowly unfolding. Keep the wisdom of our ancestors, continue the Chinese heritage, revive the lost skills, and let the wisdom of our ancestors be seen by the world.
