King of the earth and mountains, the Nibelungen that cannot be left

Chapter 1 The King of Earth and Mountains, the Nibelungen that cannot be left

Su Mo accidentally entered the Nibelungen on the subway and was caught by Dragon King Jörmungandr. Only then did he realize that he had traveled to the world of dragons.
Under Xia Mi's threat, Su Mo surrendered decisively and chose to become an undercover agent of the Dragon Clan.
Xia Mi originally thought that he had obtained a good insider and spy
Later, he gradually began to doubt life
Why does he, the boss, have to run errands for undercover agents every day?
Why does he, the Dragon King, still have to work hard to make money to support his younger brother?
Who is the subordinate and who is the tool?
Moreover, the most unacceptable thing is——
"What's going on with this little red-haired girl? Why does she call you brother?"
Xia Mi glared at the man in front of her with a pair of golden eyes.
