บท 457: Found Out

The secret room.

Gu Qing Shan was holding a jade tag in each hand, calculating the Soul Points expenditure.

Currently, his knowledge of formation had reached this world's intermediate level.

A few moments later.

Gu Qing Shan put the jade tag down with a heavy expression on his face.

The amount of Soul Points necessary to learn formation was staggering.

He would need to spend more Soul Points to reach this world's middle-advanced level.

And Qi Yan's level was at least first-rate.

And then, to be able to unlock the Two-world warp formation plate, he must be at least 1 grade above Qi Yan.

He needed more Soul Points.

Gu Qing Shan checked his remaining Soul Points amount.

To undo the two girl's Spirit Shackles, he spent 100 Soul Points.

So he had 1003 Soul Points left.

At most, he'll only be able to reach Qi Yan's standard after using all 1003 Soul Points he had left.
