Inside the Heavenly Tomb, Lucy managed to reach the 700m mark but the pressure became stronger than ever. She would take a step every five to ten seconds and she was already soaking with sweat. Her normally white face was red and exhaustion started wearing her off.
Arthur shifted his attention to his wife but found no trace of her. Actually, she disappeared from his view when she crossed the 500m mark. Normally, with his Dexterity, he could see people several kilometers away from him, like an eagle. However, the Heavenly Tomb blocked his vision thus leaving him a bit worried. Whilst it's true he has a blind trust and complete confidence in his wife's abilities, he cannot help but feel anxious about her safety, after all, she's inside a Heavenly Tomb and not an amusement park.
As Lucy crossed the 700 meters mark, the same voice from the beginning was heard again but only those inside were able to hear it.
