The Cheongdo Bullfighting Stadium, where bullfighting matches are held every weekend, has begun its 10th anniversary with the start of the King of Kings competition between the strongest bulls. The Bullfighting King of Kings competition is divided into 'A, B, C' by weight class and is held from the quarterfinals. The real preparations of the bulls and their owners for the strongest bull begin. The preparation process, such as the cow's diet management and physical training, are also different. It is said that taking care of the fighting bulls requires the same sincerity and affection as training a martial arts athlete. The story of their bullfighting challenge, where they become as affectionate as family after spending 24 hours together. We follow the breathtaking week of those preparing for the King of Kings competition. ◆ Fighting bull brothers who are always in second place, write a drama of a comeback. Spaceman Lee Sang-hyo, the fighting bulls Yeo-po (5 years old) and Yong-am-il (11 years old), have been raising fighting bulls for over 40 years, captivated by the honesty of the bulls and the charm of bullfighting without foul play, but they have always been on the verge of winning the competition. However, in the quarterfinals, both Yeopo and Yongamil won and advanced to the King of Kings. However, they were considered the weakest among the participating bulls, so few expected them to do well... In the semifinals, another dramatic reversal between brothers was born. They achieved the feat of advancing to the finals together, and although the trophy was already confirmed, Lee Sang-hyo was happily troubled over which of his bulls he should root for. Yeopo, who had just started his career as a player, and Yongamil, an old bull who was about to retire. Who will be the strongest bull in the 'Eul' weight class? ◆ A hometown friend who became a fighting bull rival The bull predicted to be the clear favorite to win the 'Eul' weight class is Bicheonmu (8 years old). Woo-ju Kim Jin-gon starts physical training at 5 a.m. to keep himself alert. He climbs the mountain behind his house for about an hour every day, visits the stadium, and conducts on-site adaptation training, focusing on improving the skills of Bicheonmu, a strong candidate to win. Kim Jin-gon, who has always grown up with cows thanks to his parents who were farmers, still lives with them as if they were family. The reason he is so focused on this King of Kings competition is because his friend Lee Sang-hyo, who grew up with him since childhood in his hometown, had two fighting bulls that both advanced to the semifinals. They met as rivals in the King of Kings competition, a situation where friends who used to drive cows up the mountain behind the house together and play together as children. The competition between the two friends, who put their 40-year fighting bull careers on the line! What will be the result? ◆ Woozooin Ha Wook-jae, a master of fighting bulls for five generations, is 43 years old this year. He is relatively young even among the Woozoo members. The reason is that he inherited the business from a family that has been raising fighting bulls for five generations. He keeps the fighting bulls the same way, feeding them porridge twice a day and taking them for walks, and so on. Ha Wook-jae’s uncle, Ha Young-hyo, still cannot forget his own cow, Beomi, and visits Beomi’s grave every morning to cut weeds. Beom-i was called the king of bullfighting, winning 19 consecutive national bullfighting championships from 2005 to 2009. When Beom-i passed away in 2010, a coffin was made, a funeral was held, and a tombstone was erected. Tae-geom (6 years old), who is in the '병' weight class and is owned by Ha Wook-jae, who shows special affection for his bulls, saying, "Cows are family," also advanced to this King of Fighters tournament. He says that it's like his own son competing, and he hopes for safety rather than winning or losing. What will be the result of Tae-geom-i, who comes from a famous family of fighting bulls? ◆ My proud baby, a house full of trophies. Park Chi-gi (10 years old), who advanced to the quarterfinals of the 'B' weight class, advanced to the King of Fighters tournament. His owner, Jo Jang-rae, unlike Woo-ju, who raises several bulls, only raises Park Chi-gi. Jo Jang-rae's greatest pride, as he takes care of his athlete children, is the trophies that fill his house. Every time he competed in big or small competitions, he would cherish even the smallest traces, and before he knew it, they had filled his house. We take a look into the daily life of Jo Jang-rae, who shows extraordinary love for cattle to the point that his wife would nag him to “take care of your family like you take care of cattle” on a daily basis. ◆ Big Day- The end of the journey to the strongest cattle.
