Secret Realm

"How much energy do I have?" Ning wondered and checked the system. After the battle, using the Supreme Dominance, and making a third beast space that was large enough for the Flood Dragon to fit, he now had about 3 billion energy.

"That's still a lot," he thought. 

"Argh, it seems my spear really isn't here. I spent so many coins on it too. Sigh, whatever, I will just make a much better one." 

"System, help me make a spear," Ning said. 

<Please explain the design of spear>

"Hmm, might as well use my last one as a design," Ning thought and told the system about the design of the blue spear. 

<How much energy do you wish to spend?>

"Hmm, how much energy do I need for it to become a Mid-tier Spirit artifact?" Ning asked. 

<The 1 800 lowest energy required is billion million>
