Sunstone, the Power to Devour the World

Since he had decided to refine the Flame Crown, Green began making preparations. A Wizarding artifact involving two worlds could be easy to refine, yet difficult as well.

"According to the records in the Soul Academy Library, the requirements for using this artifact aren't primarily about how powerful the user is. They depend more on environmental conditions! The most important things are the contract and the summoning cost."

Recalling the records in the Library, Green began comparing them with his own circumstances.

First was mutual consent. Since he intended to borrow the power of another world's sun, he would definitely need the other party's consent.

Fortunately, Green possessed the Sun Sovereignty of the Forest Fairy World. Even the Forest Fairy World Will couldn't stop him, because Green was effectively borrowing power from himself.

Under these conditions, Green didn't need to pay any price, nor did he need to be bound by any contract.

In the Ancient Era, an ordinary Wizard would certainly have had to sign a contract, with both parties jointly setting the terms and imposing all kinds of restrictions.

For Green, however, it was merely a matter of opening a permission on the sun, allowing the Sun Crown to access it whenever necessary.

The second issue was the summoning cost. In the Ancient Era, because the Wizarding World was sealed off, the price of breaking through the World Barrier grew higher and higher. The cost of summoning became increasingly enormous, until Wizards could no longer bear it.

"The two most important problems have already been solved. Next comes the refinement of the Wizarding artifact!"

Thinking of how mature the conditions were, a satisfied expression appeared on
