Was Kang Hyun Jo the Spirit at Mount Jirisan?
Meanwhile, Seo Yi Kang got interesting updates with Lee Da Won about the signal she asked her to put up on the mountain.
Based on the footage, the details on the signal moved without someone appearing in front of the camera, pointing out a new location.
Seo Yi Kang figured out that the message was pointing out at Dowon Valley and immediately alerted other rangers in the area.
Interestingly, the rescue team found the victim who was suffering from a poisoned yogurt drink.
The following day, Yi Kang visited the victim to ask a series of questions regarding the incident.
Here, she was surprised to hear that the man had found a spirit who might be Hyun Jo.
A Local Died Due to a Potato Bomb
"Jirisan" episode 4 episode 11 also highlights the incident in 2018.
It came after a park station received a call from Dr. Yoon Soo Jin about the missing snakes at the park.
After their investigation alongside Yi Kang and Hyun Jo, they found out that a couple was illegally poaching animals at the park, including the snakes, to support their business.
Due to violating the park's rules, hundreds of animals were confiscated and the couple was penalized with a hefty fine.
However, it did not stop them from illegally capturing animals and secretly going back to the mountain to hunt.
After the two passed by for their rounds, the couple set up their bait and unfortunately, the husband saw an unusual object.
He got curious and held it, but it turned out to be a potato bomb and exploded, causing his immediate death.
The incident went big, prompting their head to resign from his position.
However, Hyun Ko insisted that they saw nothing unusual during their rounds and someone might have purposely placed the potato bomb in the area.
Kang Hyun Jo's Premonition
In "Jirisan" episode 4, Kang Hyun Jo saw a clearer picture of the man behind the bomb explosion and the possible culprit responsible for a series of deaths due to poisoning.
He tells Seo Yi Kang about his vision, seeing a man with a claw scar in his hand, intentionally placing the potato bomb in the area.
Initially, she advised him just to leave these details to the police, but the newbie ranger is eager to crack the case.
During his investigation, he found out that the man who used to remove the potato bombs back in the day was the grandfather of Haedong Park's admin, Lee Yang Sun.
The old man was hesitant to discuss the details, knowing that it might affect his granddaughter's work.
However, Hyun Jo found an interesting discovery that might shed light on the case.
Here, he suspects that Lee Yang Sun's older brother might be the person behind the case.
The same goes for Seo Yi Kang, who saw the markings on his hand during the park's orientation, where the locals are invited to attend.
