First, the iron loach method in Lu Ban Shu
Is to let people's walls collapse (used to be earth walls, but now they are cement walls. It is useless). I remember when I was a child, an uncle knew the iron loach method and compared it with my father. My dad asked him to try that broken wall. When my uncle finished this method, water began to appear in the middle of the wall. My father dug up the water wall with a hoe. In addition to solving it, this is a hard way to break the iron loach. Otherwise, the water will rise more and more, and the earth wall will collapse. Of course, don't be afraid now, reinforced concrete, even if it is made of nine cows, may not be able to cross it.
If you want to see Lu Ban's book in the picture, pay attention to the lower right corner. From here on, there are many different versions of Lu Ban's books circulating on the Internet.
Second, the cooking method of "Lu Ban Shu" is immature.
Insert a pair of scissors into the steamer, and the caster immediately falls to the ground, with unbearable heartache. This is also a hard method. But there are also disadvantages. If the other person uses the method of returning the box, then you have received his pain just now. Small methods are always easy to crack, even if they can't, there are 10 thousand ways to crack them. Ten thousand broken methods can solve the craftsman's evil methods.
Third, the grinding method in Lu Ban Shu
Just keep your mill jumping and you won't be able to grind powder. This method can also be cracked by hard methods. There is a wooden grinding center in the center of the stone mill. Tap the bottom of the grinding center three times with a hammer. The stone mill won't jump again, and all kinds of methods can be cracked. My master, Lu Ban, is a stonemason, and he also broke this kind.
