In the first medical storytelling entertainment program in Korea on KBS 2TV, 'Celebrity Soldier's Secret,' the self-proclaimed 'comedic martial artist' Heo Kyung-hwan appears as a special guest, addressing the life and death of 'Headbutt King' Kim Il.

In the episode of 'Celebrity Soldier's Secret' airing on 25th, Heo Kyung-hwan, who comes as a special guest, boasts, "I recently earned a 'purple belt' at the level of a Brazilian jiu-jitsu instructor." This prompts Jang Do-yeon to make everyone laugh by giving him the title 'comedian martial artist...'

Meanwhile, a legendary martial artist who appeared on screen, expressing, "I am happy to receive treatment in my home country," was unfamiliar to the MCs. Now in his 70s and having spent 10 years in the hospital, his appearance was quite different from his prime. However, Heo Kyung-hwan, who recognized him at a glance, noted, "Everyone who is around my age knows him if they are interested in sports."

The elderly gentleman in the video was revealed to be Kim Il, 'the legend of professional wrestling' in South Korea, and Lee Chan-won exclaimed, "Headbutt!" Heo Kyung-hwan was then surprised, asking, "How does Lee Chan-won know about Kim Il?" Jang Do-yeon added to the speculation about Lee Chan-won's age, saying, "Because he was born in '69..." Lee Chan-won clarified, "I was born in '96, but the rumor that I was born in '69 has been circulating for several episodes," and added, "Kim Il is basically too famous. I saw him in textbooks during social studies and physical education classes. He was referred to as 'the idol of the sports world' in my parents' generation."

Heo Kyung-hwan explained the incredible power of the 'headbutt,' which became synonymous with Kim Il, saying, "Headbutts are now banned in professional matches. Their power is tremendous..." More stories about the origin of Kim Il's 'headbutt' and his unique training method that shocked Lee Chan-won, who remarked, "He might have died much earlier," will also be revealed.

'Celebrity Soldier's Secret,' the first medical storytelling entertainment program in Korea that uncovers the secret life and death of historical celebrities, will air the episode 'Where Did the Legendary Headbutt King Go?' featuring Kim Il on Feb. 25 at 8:30 p.m.
