The infinite universe has heavens and worlds, many races, endless disputes, natural selection, and the survival of the strong. The cultivation world is divided into different levels of cultivation worlds such as mortals, immortals, gods, and saints, and each level of cultivation world has evolved into countless cultivation realms over the years, providing cultivators with a path to the Great Dao.

The mortal world is the primary cultivation world, and the authentic cultivation system is divided into nine levels: condensation, foundation building, Jindan, Yuanying, out-of-body, distraction, merger, tribulation and Mahayana. In addition, some ghost, corpse and other side cultivators specialize in cultivating the body or soul, which is very weird, but the cultivation principle is similar.

The immortal realm is a second-level cultivation world, divided into human immortals, earth immortals, heavenly immortals, true immortals, Xuan immortals, golden immortals, immortal monarchs, immortal emperors and immortal venerables.

The Divine Realm is a three-order cultivation world, divided into Yellow God, Xuan God, Earth God, Heavenly God, Main God, God King, God Emperor, God Emperor and God Venerable.

The Holy Realm is a fourth-level cultivation world, and it is also the top world in Chaos, which is divided into three levels: Chaos Yuan Saint, Heavenly Dao Saint, and Great Dao Saint. The sage controls the law and contemplates the path of enlightenment. Those who have attained the Great Dao Sage can travel through Chaos and explore the Supreme Chaos Dao. The Dao Sea is endless, and there are few people above the Dao Saints who reach it, and it is unknown.

Note: Mortal warriors, although they do not have spiritual roots, cannot absorb and store spiritual energy, but they can boil the physical body and exercise the body. Therefore, among mortals, there is a category of physical body cultivators, called martial artists, which are divided into nine realms: refining skin, refining meat, refining tendons, refining bones, refining marrow, refining blood, refining pulses, internal strength, and fetal breath (and innate realm).

The skin refiner is difficult to hurt with an ordinary sword and is not afraid of cold and heat; the meat refiner has infinite strength and can lift the top of his hand; the one who exercises the tendons can give birth to dark energy and fight cattle across the mountain; the bone refiner has jade bones and golden muscles, which is as stable as Mount Tai; the marrow refiner communicates with heaven and earth and returns to the basics; the blood refiner is derived from flesh and blood and is not afraid of external injuries; the vein refiner has a strong internal breath and a great increase in life expectancy; the one who refines the inner strength is not afraid of internal injuries and is perfect; the one who refines the fetal breath is rejuvenated and has just entered the path.

Herbs, medicines also. One to ten years is a product, and then every ten years is added, the grade is increased by one level, and the hundred-year-old herb is a one-grade elixir.

Weapons, mortal weapons also. It is divided into three streams and nine products. The first to third grades are third-rate, the fourth to sixth grades are second-rate, the seventh to ninth grades are first-class, and those who exceed the ninth grade are called divine soldiers, and the flow of extraordinary weapons.

Brute beasts, fierce beasts also, divided into nine grades, the same warrior. The same goes for pills. There is also a difference between inside and outside the cheats, which are divided into third-rate and nine-grade products.
