Chi You, the leader of the Jiuli clan tribal alliance, has eight legs, three heads and six arms, and a cow head and a human body. And his forehead is like brass, and his bones are like iron, and he is invulnerable, and he is good at using weapons and is extremely brave.

Chiyou's eighty-one brothers are all like wild beasts, eating stones and iron, and also have copper heads and iron arms, as well as hair like blades, and all of them have special skills, and they are extremely fierce.

After the Yellow Emperor defeated Emperor Yan in the Battle of Hanquan, Chi You thought about chaos every day.

One day, when Chiyou passed by the foot of Lushan Mountain, he found a lot of rare ores, so he collected them and made many swords, halberds, knives, spears and other weapons, and the strength of his army increased instantly.

In addition, Chi You also invited Feng Bo Feilian (deer body with a finch head, a head with sharp horns, a leopard print body, and a tail like a yellow snake) and Yushi Ping Ping (shaped like a seven-inch silkworm with scaly wings on its back) to help out, and sent a war letter to the Yellow Emperor, preparing to compete with the Yellow Emperor.

In desperation, the Yellow Emperor led many soldiers to fight against Chiyou.

I saw Chi You riding a war tiger, wearing colorful battle armor, and holding different weapons in his six hands.

The Yellow Emperor sent his mount Ying Long to fight. After Ying Long was ordered, he flew into the sky with a "whoosh" and squirted a large amount of water from his mouth. In an instant, the water rushed towards Chiyou. Chi You was busy with the Feng Boyu Division.

The rain master collected the flood in an instant, and then Feng Bo blew a fierce wind and swept all the water back into the Yellow Emperor's army. Helplessly, this Ying Long could only spray water, not collect water, and the flood swept the Yellow Emperor's army apart, and it fell into chaos for a while.

Chiyou took the opportunity to lead the army to attack the Yellow Emperor, and the result can be imagined, the Yellow Emperor returned with a feather.

In the next hundreds of years, the Yellow Emperor and Chi You fought dozens of times, and the Yellow Emperor won fewer and lost more, and he was very anxious.

One day, the Yellow Emperor was thinking hard about how to defeat Chi You, and before he knew it, he fell asleep.

The Yellow Emperor dreamed that the Nine Heavens Xuannu handed him a book of war, and told him: "If you memorize the book of war, you will win the battle!" With that, the Xuannu floated away.

The Yellow Emperor woke up and found that he really had a copy of the Yang Fu Sutra in his hand. Open it and take a look, there are several hieroglyphs painted on it, so the Yellow Emperor set up nine formations and eight doors in accordance with the Xuannu Art of War, and arranged three strange and six instruments in the array, making yin and yang two escapes, and the exercises changed, becoming 1,800 formations, called "Tianyi Dunjia" array.

When fighting again, the Yellow Emperor directly led the army to charge into battle, but unexpectedly, Chiyou cast a spell - spraying smoke and spitting fog. The Yellow Emperor's army lost its way in the fog, and for a time, the formation was in chaos.

At this critical moment, the Yellow Emperor suddenly raised his head and saw the Big Dipper in the sky, the handle of the bucket turned but the head of the bucket never moved. According to this principle, the Yellow Emperor invented the guide car, identified a direction, and led the army to break out of the encirclement and save the day.

The Yellow Emperor was ready to lead his troops to a decisive battle with Chiyou again, and in order to boost the army's might, the Yellow Emperor decided to use a snare drum to boost morale. He caught a dragon-shaped beast from Liubo Mountain in the East China Sea, Kui, and a thunder beast from Razor.

The Yellow Emperor sent people to make a drum surface out of the skin of Kui, and used the bones of the thunder beast as a drumstick to make a big drum. When this drum is struck, it will resound for 500 miles, and if it is struck a few times, it can shake for thousands of miles. In addition, the Yellow Emperor also summoned the drought goddess to help in the battle.

When the Yellow Emperor heard that Chi You had refined the mount war tiger with the alien demons outside the sky and turned it into a tiger sword, he was shocked for a moment and was busy asking for help from the gods, and the gods then took the bronze of the first mountain and cast the Xuanyuan sword to the Yellow Emperor to help him.

Next, the two armies faced each other, and the Yellow Emperor set up the "Tianyi Dunjia" formation early to lure Chiyou's army into the formation. Then he commanded the beating of the drum, and the heavens and the earth shook.

After hearing this, the morale of the soldiers of the Yellow Emperor surged, and they bravely killed the enemy, defeating Chiyou's army to the ground. Seeing that he was about to be defeated, Chiyou and his eighty-one brothers rushed fiercely and bravely.

At this time, Chi You rode his new mount, the Iron Eater, holding a blood-soaked tiger sword, and clinging to the Soul Breaker Whip made from the tail of the war tiger, and fought the Yellow Emperor head-on.

Chi You swung at the Yellow Emperor's army, and the soul breaker whipped them so that their souls were scattered, and they had no power to parry.

The Yellow Emperor saw that Chi You was indeed difficult to deal with, so he ordered Ying Long to spray water. Ying Long opened his huge mouth, and the river-like water jetted out from top to bottom, and Chi You also hurriedly ordered the Feng Boyu Master to set off a violent storm and hit back into the Yellow Emperor's array, and the flood on the ground suddenly swelled, and the waves were monstrous.

At this time, the Yellow Emperor ordered the female Lu to go into battle. I saw a rolling wave of heat spraying out from the female body, and in an instant, the storm and rain set off by the Wind Bo Rain Master subsided. Feng Bo and Yu Shi had nothing to do, so they fled in a hurry, and the female Lu also retreated because of the great consumption of divine power, and the next thing was the head-to-head battle between the Yellow Emperor and Chi You.

The Yellow Emperor stepped forward alone to fight with Chi You for a while, and for a while, the sword light and sword shadow, the soul-like red light emitted by the Tiger Spirit War Knife, and the dazzling golden light emitted by the Xuanyuan Sword reflected each other, and the light went straight into the sky, and then suddenly dispersed, shaking the heavens and the earth!

The two evenly matched sword qi both carried unstoppable power, roaring towards the entire heaven and earth, and some of the soldiers of the two groups of armies were directly killed by this sword qi, and some were lucky, but they were not dead or seriously injured. I secretly used my divine power to open my branches and block this terrifying sword qi for Jiusui He and the flowers and trees including it.

When I looked at it again, Chi You's soul whip was directly cut off by the Yellow Emperor's Xuanyuan sword, and he lost his divine power, Chi You simply threw away the soul whip, and the six hands worked together, holding the tiger spirit sword, roared, and slashed directly at the Yellow Emperor, at the moment of emergency, the Yellow Emperor's mount Ying Long stepped forward to block the tiger spirit sword, and was immediately split in half, fell to the ground, and no longer moved.

The Yellow Emperor endured the pain of losing his mount and swung the Xuanyuan Sword, and with a single sword, it pierced Chiyou's copper-like forehead, and Chiyou fell from the iron-eating beast. After the Yellow Emperor ordered someone to capture Chi You alive, he put him in chains and killed him completely with the Xuanyuan Sword. Fearing that he would do something wrong when he died, he ordered his body and head to be buried in different places.

The Hundred Years War between the Yellow Emperor and Chi You has finally come to an end.

But it is said that the soul-breaking whip fell into the earth, forming a river ditch, impartial, between me and Jiusuihe......
