The cultivation of Dou Qi is different from martial arts, and orcs who cultivate Dou Qi in the early stage need to constantly train their bodies to make their bodies stronger, so as to stimulate the qi and blood in their bodies and produce weak Dou Qi.

After the fighting qi is generated, it can strengthen the body in turn, making the already very strong body of the orc clan even stronger.

When the body is stronger, more fighting energy can be born in the body, and after the fighting energy is generated, it will continue to improve the strength of the body, forming a virtuous circle.

When the body of the orc clan is strengthened to a certain extent, they can directly absorb the aura between heaven and earth to generate more fighting energy, making their bodies more powerful.

After the formation of the Dou Qi cultivation system, the orc clan borrowed from the Yu Clan's magician system and divided the Dou Qi cultivators into two levels: warrior apprentice and junior warrior.

After the appearance of the Dou Qi, the Terran and the Orc Race continued to communicate and improve their respective cultivation systems. As a result, the martial arts cultivation system of the human race and the fighting spirit cultivation system of the orc race have been greatly improved and improved.

During this period, the orcs also slowly mastered the human script through contact with the human race. Because the orcs did not have their own script, they regarded the Terran script as the common script of the orcs. Even so, only the upper echelons and leaders of the various races of the orc race can learn the Terran script.

In the 23rd year after Yuan Hao fell asleep, the Yu clan also mastered some human scripts through the captured orc captives.

After that, Feng Yan thought about it with the wise man of the mermaid, and after borrowing the script of the human race, he finally created a script shared by the feather and mermaid people.

The elves who live on the tree of life are born with a magical language.

In recent years, the elves have borrowed from the feather clan's magic system through a few encounters with the feather clan. Writing their own language, combined with various magical spells, they formed a higher script with special powers, Elven script.

At a time when all races in the Tian Yuan Continent were developing rapidly, a race was gradually formed within the Origin Mountain Range.

This race calls itself the Demon Race, and they evolved from the fierce beasts and all things that have their psychic intelligence.

Some powerful beasts slowly developed spiritual wisdom because they devoured the essence of the sun and the moon, or found some top-grade spirit grass.

After these fierce beasts possessed their intelligence, they looked down on their former kindred and disdained to be in their company.

In order to distinguish themselves from the fierce beasts, they formed a new race together with the spirits and spirits of the mountains and rocks that were born after the birth of the spirit of the grass and trees, the demon race.

The demon clan, because of their innate talent, can easily find those heaven and earth spirit grasses hidden deep in the origin mountain range.

By consuming these spiritual grass and spiritual objects, the demon clan became more powerful. Those who are the most powerful beings in the demon clan can command the beasts and make them submit to them.

In the 25th year of Yuan Hao's sleep, because of the growth of the demon race, the dwarf race, whose living environment was oppressed, left the origin mountain range, defected to the human race, and became a vassal of the human race.

Dwarves are short in stature, and when they reach adulthood, they reach the waist of an adult at most. But the muscles of the dwarves are very well developed, and they are all powerful men.

After seeing the Terran houses, the Dwarves moved out of the ground and moved into houses of their own making.

The dwarves worked with the Terrans to extract iron from the ore through the coal mines they found underground, using the Terran furnaces.

After the advent of iron, the human race has developed by leaps and bounds. Through the skilled craftsmanship of the dwarven craftsmen, they turned iron into a variety of weapons and household utensils. The living environment of the human race has been greatly improved, and the human race has directly entered the age of iron.

In the decades that followed, the Terrans entered a period of rapid expansion. A large number of Terrans left their territory and expanded into the surrounding lands, forming tribal confederations dominated by their own leaders.

In the process of the expansion of the human race, the iron tools invented by the human race inevitably fell out, and all the races in the Tian Yuan Continent had some iron tools to a greater or lesser extent.

The civilization on the Tian Yuan Continent has taken a big step forward as a whole.

During this period, the population of the human race was greatly expanded, and they occupied nearly half of the land in the eastern land of the Tian Yuan Continent.

In the 57th year of Yuan Hao's sleep, Fuxi, who had reached congenital perfection and had greatly increased his lifespan, was in the prime of life at this time.

Fu Xi, who was in the golden years of his life, made an act that most of the human race did not understand. Fu Xi passed on his identity as the common leader of all the human tribes to a human race called Shennong.

Speaking of Shennong, he is also well-known among the tribes of the human race today.

After Fu Xi created the cultivation system of martial arts, the overall strength of the human race has been strengthening. But even so, as the aura between heaven and earth has become more and more intense over the years, there have become more and more powerful fierce beasts.

In the process of hunting fierce beasts, the human race inevitably paid a lot of casualties, and a large number of human races were sacrificed under the minions of fierce beasts.

When Shennong was a teenager, he felt sad for his compatriots who were constantly sacrificed under the minions of fierce beasts.

As an adult, Shennong set himself a lofty goal. He wants to find a new source of food for the Terrans, so that his compatriots will no longer sacrifice a lot of food in the mouths of the beasts.

After more than ten years of continuous efforts and experiments, Shennong successfully found several plants. Terrans can plant them and harvest their fruits for food.

Shennong named the plants he found as five grains.

The reason why the power of the human race has been able to expand so hugely over the years is that Wugu has played a large role in it.

Because of his great contribution to the human race, Shennong is remembered by the people of various tribes of the human race.

Because of his outstanding contribution to the Terrans, under the acquiescence of the leaders of various tribes, Shennong successfully took over Fuxi's position and became the second Terran co-leader without experiencing a trace of turmoil.

After passing the position of the leader of the human race to Shennong, Fu Xi lived in the Haotian Temple for a long time and became the high priest of the human race to worship the gods of Haotian.

After becoming the new leader of the Terrans, Shennong felt that among the various tribes of the Terrans, every year some of the tribesmen lost their lives due to illness and various poisonous insects.

Shennong therefore made up his mind that as the leader of the human race, he would do something for his people so that they would no longer suffer from illness.
