The Human Race's third co-ruler, Xuanyuan, had finally brought his merit to completion.
After resolving the Human Race's currency and systems of weights and measures, the Human Race entered a fast lane of development.
Countless creations and inventions emerged one after another. During the later years of Xuanyuan's rule, every aspect of the Human Race developed tremendously.
In agriculture, they implemented cultivated farming, sowed the various grains at the proper times, invented pestles and mortars, opened orchards and vegetable gardens, planted fruit trees and vegetables, raised silkworms on mulberry leaves, domesticated beasts and birds, and practiced animal husbandry.
In sewing and weaving, they invented looms and carried out textile production, making clothes, shoes and hats, tents, felt, ceremonial robes, fur garments, canopies, armor, banners, and helmets.
In pottery, they made bowls, dishes, cauldrons, steamers, trays, basins, and stoves. In metallurgy, they smelted copper and made bronze tripods, knives, coins, gongs, ladles, bronze mirrors, bells, and firearms.
In construction, they built palaces, imperial halls, courtyards, Bright Halls, towers, pavilions, fortresses, buildings, gates, stairways, silkworm rooms, ancestral temples, Jade Chamber Palace, and more.
In transportation, they made boats and oars.
In weaponry, they made knives, spears, bows and arrows, crossbows, six great banners, flags, Five Directional Flags, horns, war drums, military tallies, scaling ladders, siege towers, swords, and equipment for archery and charioteering.
In daily life, they developed cooked food, porridge, rice, wine, meat, scales and rulers, measuring vessels, compasses and squares, inkstones, tables, felt, banners, seals, pearls, lamps, beds, mats, football, and more.
Combined with the earlier establishment of official administration and the dissolution of tribes, Xuanyuan had made enormous contributions not only to unifying the Human Race through war, but also to its people's livelihood and enlightenment.
Yet during the final stretch before his completion, Xuanyuan encountered a difficult problem.
