Probe
Sam looked at the dark mass of energy and was stunned. It struggled like crazy as it tried to get out his grasp. It is like a sentient creature trying to get out his grasp. But he didn't let go and used the golden flames to burn it down.
But as the golden flames hit it, the dark energy tried to absorb the energy and in fact it did, but only half of it was absorbed and the other half made the energy turbulent. It is as if its screaming in pain due to the torture of being burned.
Sam tired many methods and every elemental energy that was being injected into it is being absorbed, but due to the superiority of Sam's elemental energy that was obtained due to the bloodlines of the beasts, the energy is being tortured.
After some thought, Sam took out a container used to make medium sized liquid energy cells and forcefully placed it inside before sealing it.
The energy struggled for a long time and after some futile attempts, it became dormant.
