The Demon City has two deepest locations: one is the Demon King's Hall at the highest peak, and the other is the Forgotten Hall in the depths of the Grave District.
The danger level of the two cannot be compared, but in terms of the bizarre and the unknown, the Forgotten Hall in the Grave District is far more mysterious.
"The Grave District does not bury the remains of the Demon King's kin or subordinates, but rather the remnants of past leaders of the Demon City and the echoes of various Demon Kings. In terms of strength, they may not even possess half or even one-tenth of their peak power, but the most terrifying aspect is their sheer number and the chaotic invasion!"
Charlotte said solemnly to Wu Qifu, "For thousands of years, the Church has sent countless teams into the Demon City. This did not start only after the appearance of the End Times Giant; long ago, the Church's exploration of the Demon City has been ongoing, and the exploration of the Grave District has never ceased. However... no one has ever reached its true depths!"
"The Grave District of the Demon City is bottomless!"
