Controlling three energy

Julian's mind raced as the system's words echoed in his head. He thought, Since it allows me to tap into the death energy itself, Does this mean I can be immune to the corruption of the Death Energy?

His gaze turned toward the ongoing chaos, the shadowy figure still wreaking havoc. It's worth testing. Even if I can control it just a little, it might be enough to recover, to turn the tide.

With that thought, he made a swift decision. "System, build the House of Necromancy," Julian commanded, his voice firm with resolve.

The system's reply came almost instantly: "Yes, Host."

Julian waited and time seemed to stretch forever as his heart beat in anticipation. After what felt like an eternity but was only a minute, the system spoke again.

"Host, the House of Necromancy has been built. You are now able to harness Death Energy to summon lifeforms to fight for you."
