As an adult, Kuchulin studied martial arts from Scathacha, the owner of the mysterious land. During this period, he captured Scathacha's rival beauty warrior Oyfe, and made her give birth to a son, Conra Ohe, who died at the hands of Ku Lin Qiu before the cattle fight. Later, Kuchulin became one of the most important members of the "Red Branch" and was active in the front line of defending the motherland.
He is invincible on the battlefield. As long as he starts fighting, his body will become extremely deformed and weird, which will make the enemy fear: "One eye is sunken and the other eye is abnormally protruding; The mouth is big and wide to the ears; The head became extremely huge, glowing with strange light, creepy, and the hair was tall and hard as a bristle. It is said that many people will be scared to death by his appearance when they see him. There is also a saying that Kuchulin has seven fingers on each limb and seven pupils in each eye, and no one can control him when he is angry (note: this statement was included in The Concise Encyclopedia of Britain, edited by British Encyclopedia Company in 20 10 and edited by China Encyclopedia Publishing House).
In the war between Ulster and Connaught, Kuchulin has been supporting the inferior Ulster army for seven years and bravely confronting the joint forces of the three countries attacking from Connaught. Although he failed to protect Ulster's bull, he succeeded in delaying the allied attack on his own, caught Maeve, the chief culprit of the war, and finally released Ulster on the condition that she could not be invaded again.
However, his life was unfortunately short because of impulsive belligerence. Because he was aggressive and reckless, he killed his only son Kenrak (that is, Kanglai) and his old friend Fodia when he had to. He was cursed because he despised war and the courtship of Morrigan, the goddess of death. After the story of cattle fetching, Ulster was defeated by the allied forces in the second Muccini Plain Massacre, and Kuchulin, who was in chaos, was attacked by Karadin and Dana, the son of coupland, and was unable to return to heaven. Before he died, he tied himself to a stone pillar, and then his arms and head were cut off by the enemy, while Morrigan was so happy that he became a crow standing on his shoulder. The story about him is mainly compiled in a legend in Ulster, Qinbo Cuailgne. Today in Ireland, poems and statues praising Kuchelin are still preserved. Despite the controversy, Kuchulin is still regarded as one of the greatest national heroes of the Celtic nation. Riverdance, a grand Irish traditional tap dance drama, also has his repertoire.
