To purify the water from a certain river the monks have carved a section of the river that goes over a stone bed. Through holy carvings of gods, godesses, and holy symbols and then the river flowing over them, it purifies the water making it safe for drinking and/or makes it holy water. For rivers that do not have natural rock bottoms, large smooth stones can be carved and added to the water to fully cover the bottom.
The Chinese, when attacking a castle or fort, flew kites over the city wall and used the length of string it took to get it there as a measurement to know how far they had to dig a tunnel to get under the wall.
Silk Armor? The Mongols wore silk undergarments under layers of leather armor. Why? Because silk is very strong. If an arrow hit them and made it through their armor, it would usually not have enough energy to puncture the silk. It could still enter their body but, because the silk would not break, the arrow's barbs could not do their work and the arrow could easily be removed leaving a relatively clean wound considering normal arrow wounds.
A new substance is found in an out of the way area and kept very quiet. It is found to make a perfect counterfeit diamond. Only the most expert of expert appraisers would even have a hope of noticing that it is fake. Only one problem: if it gets wet it starts to slime and if it is saturated, it turns into a glob of gel.
A tree was given as a gift at one time to a city. Every year the tree is the center of a large parade as the tree is towed by oxen or large horses in a large wagon through town.
Village has a nearby natural substance that comes from the ground and burns well when lit. They use it only locally and try not to let the secret get out.
hey im new to this site but was here years ago w/ another name. anyways dont remember so im newbie by default.
Firstly, I am a sci-fi reader and I hope to meet success with my writing.
My favorite series of books are Larry Nivens RINGWORLD tetralogy (Ringworld, RingWorld Engineers, The RingWorld Throne, and RingWorlds Children)
For those that havnt read the ring world is the greatest artificial structere ever discovered.
A ring, its circumference equal to earths orbit, it is built around a sol-like star. Shadow squares halfway betwwn the ring and the sun provide 15 hours of night in a thirty hour day. 70 days equals one falan (one full rotation of ring world. The inner surface-the one exposed to the sun, is terraformed and is one millionkmwide cntrifugal force provides gravity, and rim walls 1000km high keep the atmosphere in. Population of RNH(ringworld native hominids)
estimated in the trillions.
The origins of who built it and why are too sticky to get into. But the ringworld , millions of years ago, was populated bt A race called Pak Protectors. Protectors are ancestors of all homo sapiens. they populated ringworld with homo erectus, but left no predators in the ecology. hence, hominids evolved into every ecological niche. (Vampires, Carrion Eaters, Giant Herbivores, Small Carnivores, some built great technologies and went interstellar. Oh, and ringworld is 300 million times the surface area of earth. post if youre interested, Ill elabortae on native species and alien vistors
