Walker Of The Worlds

Half an hour passed before the lake had been emptied out.

Much to Lady Kang's surprise, Lin Mu didn't seem the least bit tired and she could tell this due to the stable immortal Qi fluctuations coming from him.

'He really did store the entire lava lake away,' Lady Kang thought in slight disbelief. 'It's as if he didn't need to use Qi to do this at all.'

Though she didn't know that on some level, she was correct. Lin Mu used the ring's power to store the Lava Lake away, thus he didn't have the same level of consumption that a normal spatial storage tool would have.

The reason for consumption of Qi when using a spatial storage tool was due to the fact that not all spatial storage tools kept the space inside them at maximum volume. Instead, one could think of the space inside them like a stretchable rubber bag.

If one wanted to store items inside them, they would have to expend some energy to stretch the bag; in this case, using Qi to expand the space to a bigger size. Thus, the consumption was two fold, the first being to expand the storage in the spatial storage tool, before using more energy to transport the items inside them.

Of course, this could only be done until a certain limit before the space wouldn't be able to hold and either break apart or the user would simply not have the Qi needed to expand it further than that. And the bigger the spatial storage tool, the more energy one would need to store items if the space inside continued to grow.

This was also why storing mass items like what Lin Mu was doing with the lava or other junk like the literal mountains of soil and rocks, was not something people normally did.

Of course, higher quality Spatial Storage tools had better efficiency and didn't need as much Qi to store items. But even the highest quality spatial storage tools would have a certain cost to them.

But in Lin Mu's case, that cost to expand the storage was nil.

The space inside the ring was constant and didn't seem to change. As such, the only cost he had was the Qi needed to transport the items inside it, which was mostly negligible to Lin Mu.

"Here we go." Lin Mu said as he stood up and looked at the sphere which had been left lying at the bottom of the lake.

With how deep the lake was and now that the lava had mostly been stored away, it was quite dark there.
