After all, when you're fighting the Power of Heaven and Earth.
First, the Power of Heaven and Earth will seal your Spiritual Power. It can't seal the Spiritual Power within your body, but it can seal the Spiritual Power outside your body.
The Power of Heaven and Earth will seal the Spiritual Power outside your body. To be precise, it will seal all the energies around you, but these energies can circulate normally; however, they won't allow you to absorb them.
After all, when you're fighting the Power of Heaven and Earth, it's impossible for it to let its own resources aid the enemy, so it will seal any form of energy near you.
Furthermore, the Power of Heaven and Earth will slowly seal the Spiritual Power that you use externally.
In other words, when you fight the Power of Heaven and Earth, you can only use Spiritual Power to enhance your physical qualities, and you can't use Immortal Technique.
