"Mozi Gongbo" records: "Gongbo is the weapon of Chu State to build ladders. If it succeeds, it will attack Song. " "The Warring States Policy and the Public Transport Plate Set a Machine Seal for Chu" wrote that Mozi said, "Seeing the public is a ladder." "Huai Nan Zi" said: Lu Ban is defeated by the public, and the Chu people are also defeated. He is a wise man of the son of heaven and can be a ladder. Xu Shen's "Brief Training of Huainan Zibing" notes: "The ladder can stand on the cloud, so you can have a bird's eye view of the enemy city". "Tales of Different Stories" records that Lu Ban once carved a "map of Kyushu" on a stone, which may be the earliest stone carving map. In addition, in ancient times, it is also said that Luban carved exquisite stone phoenix.
At that time, there was a legend that carpenters often ran around alone. In case of emergency, they all had self-defense skills, the most magical of which was The Book of Ruban. The esoteric "Lu Ban Shu" is said to be full of contents and spells, and this system of Lu Ban Fa has always been strictly prohibited! It is unknown how many kinds of "Lu Ban Shu" and "Lu Ban Fa Lu Ban Shu" there are among the people today. There is a saying in the industry: "Lubanfa, 480", which is enough to explain Lubanfa.
After 2000, people cracked another identity of Lu Ban in The Book of Lu Ban. Although The Book of Lu Ban is a craftsman's book, it is divided into two parts. But the lower part is no longer the production method of civil buildings, but the occult techniques such as yin and yang gossip and Taoist spells. This also implies another identity of Lu Ban, that is, he is actually a warlock of Yin and Yang. Lu Ban was a man with outstanding talent in ancient times. Even in modern times, people have learned the knowledge in Lu Ban's books, which is very useful.
