Indeed, this hall was very huge. The group walked for an entire hour but they still couldn't see its walls. Mo Wuji inwardly praised his luck. If Yu Zhenna and the other two weren't near the door, he might have directly entered. The moment he entered, Yu Zhenna might discover the imprint he got from killing that brown-haired youth and the consequences would be too disastrous to consider.
After walking for another incense's time, the group stopped. In front of them wasn't the wall of the hall, but a rune sheet.
This rune sheet looked transparent and it rippled with powerful dao laws. Ordinary methods definitely weren't able to open those dao runes. At the same time, Mo Wuji wondered whether his Kun Wu Sword could slice this sheet open. After all, Kun Wu was one of the ten ancient godswords.
Mo Wuji's spiritual will was completely unable to penetrate through this sheet.
