As Wang Zijia continually consumed his mana, the cave sloped downwards, giving birth to a blood-red jade staircase.
Stepping on the stairs, Wang Zijia kept digging downwards. Only after reaching a depth of about ten meters did he stop going deeper and started expanding horizontally, carving out an underground space.
While digging earlier, the space wasn't too big. The mud from the excavation, when compacted and transformed into crystal for the cave walls, didn't leave much surplus.
However, as Wang Zijia expanded the underground space, there was more surplus mud turned into crystal. He had no choice but to store it in his storage bag, filling it with a bag of crystal soil in a moment.
Wang Zijia piled it up in a corner of the backyard and continued digging.
After three trips, a large mound of crystallized molten rock formed in the backyard, causing Wang Zijia to stop his efforts.
