In the world they are in, Luna bid farewell to Dong-in as her health is deteriorating. On the other hand, Shin Jae is devastated that he gave the half of Manpasikjeok to Tae-Eul as she heads to the axis realm with Lee Rim.
Meanwhile, King Gon and Jo Yeong arrived in the year 1994 at the Kingdom of Corea, on the night of the treason. Jo Yeong killed Seung Heon, one of the accomplices. Then King Gon asked Jo Yeong to guard the gate, but he insisted to join King Gon in his battle at the Cheonjongo. Jo Yeong insisted that this is the last chance he has to protect his Majesty. As King Gon was puzzled about what would be the consequences if things will change as they progress, he kept his faith that it will be for the better. Besides, he believe that he's not alone in his fight, the Four Tiger Sword leads him as well.
Meanwhile, in the future, Tae-eul keeps Lee Rim on watch while pointing a gun to him. She planned to kill Lee Rim if King Gon won't succeed, as they're inside the axis realm waiting for things to unfold.
At the night of the treason, young Gon holds the four tiger sword facing Lee Rim. As one of his men pointed a gun to young Gon waiting to kill him, Lee Rim instructed to shoot but the glass ceiling breaks and pieces of it fell to the ground. Young Gon looked for a place to hide as he stepped down and escaped, while a piece of broken glass cuts Lee Rim's hand where he holds the Manpasikjeok. He then lost his grip as he covers his head.
Jo Yeong fires his gun to Lee Rim's men. He makes his way inside and in his best fighting skills he made it through. King Gon started shooting as well, in his finest skills he fought well. During the battle, the royal guards were alerted and were on their way to Cheonjongo.
Lee Rim, with blood dripping in his right hand, picks up the Manpasikjeok. His blood tainted the legendary bamboo which puts life into it. King Gon's half piece disappear. As he looks up, Lee Rim runs to escape.
King Gon runs after for Lee Rim, on his way out he saw Jo Yeong on his knee. He got shot in the middle of the fight. King Gon with a firm look gave Yeong a nod. Signaling that he is leaving him to go after Lee Rim. Yeong wrapped his arm to young Gon checking if he is alive. Gon tucked his hand in response. Then, Lady Ok-Nam arrived with the assemblymen.
In the axis realm, the future Lee Rim is shocked to see the half Manpasikjeok slowly disappear in Tae-Eul's hand. The whole Manpasikjeok is with his old self. This means that King Gon will not come back and he is stuck with Tae-Eul in eternity.
So, Shin Jae brought his foster mother to the hospital where a sick Shin Jae lay in bed. He thought that she will abandon him as he fled the hospital, but Hwa Yun runs after and hugged him as she thanked him for being her son as well.
Continuing the night of the treason in the past, Lee Rim runs to the forest where the red obelisk opened revealing eternity and affinity. King Gon caught up with him. Using the four tiger sword he stretched out and struck Lee Rim. He gets hit with the bamboo, but he managed to stand up as he grabbed the mystical bamboo.
King Gon then pointed the sword to Lee Rim. He recited the sacred words embedded on the sword as beheaded Lee Rim, spreading his blood through the bamboo that surrounds them.
Meanwhile, The yoyo boy is the reflection of the Manpasikjeok who holds the balance. In every event of King Gon and Tae-Eul's life journey, he existed and witness them live in time.
