Apocalyptic Overlord is forced to become a dual savior.

Yu's Family before the apocalypse was only a rich family but after the apocalypse, they were the powerhouse and one of the people who ruled the world. Lady Yu had five children and all boys. They all were prodigies and each was more heaven-defying than the other. And like this, the 5th son was not only a genius but also a person who could use 5 abilities. He became the Leader of the Yu base which protected millions of people and after 10 long years only the Yu base survived with a population of 100 million people and this was the population of the world.

Elder Brother Yu: Little brother we have found a way to save our world.

Yu Liqin: That is good news brother.

Second brother Yu: Yes, But we need to fuse our world with another world.

Yu Liqin: Oh, It might be difficult.

Third brother Yu: Yes, But we need to make the people over in that world feel Goodness for us.

Yu Liqin: That will tough.

Fourth Brother Yu: Exactly that's why the most powerful person should go as an envoy, Right?

Yu Liqin: Of course.

All 4 brothers: So, You go.

Yu Liqin:...(＃`Д´) Not me!!

Base vice Leader: Boss, Worry not. As long as there is a matter we will call you back anytime.

Base Military Leader: Boss, Go and enjoy, I will protect the base.

Base Research Leader: Boss, please gather all materials and food when you come back at intervals!

Base Lead Doctor: Boss, Please collect all medicine available there!

Yu Liqin:...I hate you all! All of you! Bastards!

The world Yu Liqin was sent to was another problem, It was a novel world, At first, there was no problem but suddenly the dungeon opens and nonsense started and the Protagonist was from Korea...China was destroyed under the siege of S-class dungeon monsters and the Chinese ran to Korea to get shelter..

Yu Liqin: How the hell can I let my country be destroyed?!!

And so Yu Liqin sometimes went to his world to solve matters and sometimes ran back and made a guild to protect his country before the dungeon outbreak.

Nam Ji-woo: My baby is independent and brave, bold and fearless, extremely powerful, can shoulder responsibilities of the whole country, and is patriotic but...I hate it!! My baby doesn't depend on me! Take me as a rival! I! Quit! Being! Korean! Must go to baby!

Elder Brother Nam: Why do you need to go? Get the person here.

Second Brother Nam: I don't dislike it, You should make good connections!

Third Sister Nam: Woah! Real-life BL story!! Ah!! Little brother go and chase your wife!
