Chapter 368: Self-Binding Cocoon? Transforming into a Butterfly!_2

```

Red, orange, yellow, green, blue, indigo, violet—like a rainbow, the show of fireworks was splendidly beautiful.

However...

The Spirit Binders present, with expressions of amazement on their faces, were not astonished by the gorgeous display but by its deeper significance—tapping into the energy of heaven and earth!

As everyone knows, the first three ranks of a Spirit Binder—civilian, soldier, and scholar—are limited to the body's adaptability to Spiritual Energy and the enhancement of its quality and quantity.

But the human body is like a balloon, it can be greatly expanded by Spiritual Energy, but it can't inflate indefinitely.

This also means that no matter how hard you rack your brains, there is ultimately a limit to the amount of Spiritual Energy one can store.

Only upon reaching the Warrant Officer rank can one break through the barrier between the body and the world, allowing the exchange of energy between the two, and begin to harness infinite energy.
