Unlucky earthling Jinwoon has the worst luck ever. At work he is being terrorised by his boss. He has no love life and his 'family' life is a pain. His life sadly ends before he can change his ill-fate destiny.

Sung Hoon is the soon to be king of the Kingdom Namgyeong. He was raised by his single father in another kingdom. After his father's death he is brought to Namgyeong. 

After his death, Jinwoon transmigrates to an alternate universe where a mysterious being tells him to find the most powerful person on the planet. 

While Sung Hoon is told that Jinwoon is the only one who can help him save his planet. 
  
Trying to save the planet, Jinwoon (re)discovers things from his past and his new future.

How far do Jinwoon and Sung Hoon need to go to save their (new) world?

VERY VERY SLOW READ.

"What should we do with that Helame?" Sung Joon stared back at the ship. The cage with Helame was not visible. Sung Hoon was silent for a few minutes. "We'll take him out, while Jinwoon and Hara are doing their experiment."

He turned to Mong and Kubo. "Take him to the caves. He might open up after that." But Kubo and Mong were shaking their heads. "They will tear him apart. It's better to bring some here to talk to him." Mong replied. Everybody agreed with him.

"We'll take him out of the cave when you arrive." Sung Hoon turned towards Jinwoon. "Let's call..." "Sung Hoon-nim, Jinwoon-nim, we have a problem! The ship is being hailed. What should we do?" Seo Ho sounded nervous. They all turned and ran back.

Sung Hoon couldn't run as fast so he and Jinwoon, who stayed near him, came in last. They could see a blue bottom flashing.  "What should we do?" Kubo looked at the others. Everybody was staring at the blue bottom without moving.
