Regarding the Luban lock, Lin Tian had already informed Xv Jiazhi about it. For this reason, they both had specially researched the object.
In fact, through the internet, one can find many enthusiasts who love mechanical skills. To them, the Luban lock is a highly interesting puzzle. It is said to have appeared as early as the Spring and Autumn period. It has survived until today, with a total of 13 common types. Creating a model simulation using a computer is not a difficult task.
The Luban lock that the Wang Family brought from Tianya Haijiao City supposedly sets off mechanisms and destroys the items within if not opened in the correct sequence and brute force is used.
As far as Lin Tian knows, apart from being a toy, the Luban lock is also an intangible cultural heritage. Without the Luban lock, there would be no mortise and tenon joints, which played an essential role in ancient architecture and remains an indispensable technique today.
