A brand new teaser for tvN's upcoming blockbuster drama 'Arthdal Chronicles' hints at a grand-scale adventure about identity, strength, and heroism. 

In the new teaser, the story's male hero Eunseom (played by Song Joong Ki) faces an identity struggle after being called "a monster's son". Constantly searching for answers to where he comes from and where he belongs, Eunseom can be seen taking on dangerous challenges after another, as he journeys across the fictional land of Arth. 

Finally, as the teaser comes to an end, Eunseom promises the young Tanya (played by Kim Ji Won), "I'll come rescue you again. Stay alive!"

The epic adventures of tvN's 'Arthdal Chronicles', also starring Jang Dong Gun, Kim Ok Bin, Choo Ja Hyun, Jo Sung Ha, and more, premieres this June 1 at 9 PM KST.
