This Is My Primitive Tribe

Hydropower is one of the earliest natural forces harnessed by mankind.

People only need to utilize the drop in water levels to obtain strong and continuous power, replacing some tedious and repetitive labor.

Among the devices that use hydropower, the most typical are the water wheel for irrigation, the water mill for grinding grains, and the water beetle for crushing various things.

Of course, although these devices have relatively simple structures, they require high standards for tool making and woodworking skills, which someone like Jiang Xuan, who is only half-skilled, definitely couldn’t produce.

However, that’s okay, Jiang Xuan only wants to make a hydropower device to grind medicine.

He only needs to make the most primitive and simple hydraulic pounding device.

Patiently grinding the medicine in the stone mortar, Jiang Xuan said to Chi Shao, "I suddenly thought of something that can automatically grind medicine. If we can make it, you won’t have to work so hard in the future."

Chi Shao asked curiously, "Really? What does it look like?"

Jiang Xuan casually picked up two sticks and explained, "Look, we use sturdy wood as a beam, carve one end into a hollow and attach a pestle to the other end."

"Then, I only need to prop up the middle of this wood and place the end with the hollow under a stream of water bamboo."
