Boruto and Ohnoki head to the rendezvous point, but they stumble into the Hidden Stone Shinobi Training Grounds, which are protected by a barrier. Ohnoki tells Boruto that the only way out of the Training Grounds is to find his heart of stone, something that can only be found once in a lifetime when a person comes to terms with their will.
It's surrounded by
a powerful barrier.
إنّها محاطة بحاجز قويّ
Eine mächtige Barriere wurde
um diese Steppe errichtet
Estamos rodeados
por una poderosa barrera.
Estamos rodeados
por una poderosa barrera.
Una valle protetta tutta attorno
 da una spessa barriera.
Ela é cercada de uma poderosa barreira.
По всему периметру здесь
стоит сильнейший барьер.
