The soil is extremely hard here, making the task of excavating around it very challenging. Chu Linfeng and Lin Ruoxi spent half a day but could only dig a small pit, thanks to the Cyan Frost Sword's ability to cut through iron like mud. Otherwise, even a small pit would be difficult to achieve.
"This isn't working, Lin Feng. To excavate this Immortal Crystal would take at least half a year, maybe even a year, at this rate. But we can't use powerful Martial Skills here, one because they might destroy the Immortal Crystal, and two because the noise may attract others, which would cause complications if they show up," Lin Ruoxi said, frustrated as she looked at the small pit before her.
