The Sword Is in the Heart, the Tao Is in the Heart

Inside the Nether Cave, the Netherworld is making noise, and outside the Netherworld Cave, the sky is coming. There is no need to guard a weak seal and break it... As long as the intention in my heart is true, I can kill Netherworld with one person and one sword. Keep the sword in your heart and the Tao in your heart. Don't look back and move forward bravely!
