Replacing the steady supply of criminals with 15,000,000 Ordinary Summoning Scrolls would be worth it. Michael would lose the supply of SoulStar Fragments and Soultrait Symbols, but he could do nothing about it. If the Valyr couldn't maintain their supply, he would have to find a different source to procure SoulStar Fragments.
Asking for so many Ordinary Scrolls might sound stupid to others, but Insert changed everything. The Scrolls were definitely worth it. Even with Extraction, Michael could transform 15 million Scrolls into 15 to 23 Legendary Scrolls. Even if the Legendary Summons would be the exiled Silverfangs, Michael could live with that. It wasn't like the Silverfangs were weak, after all.
'Should I start trading 1-Star Soultraits or upgraded Soultrait Symbols with Ordinary Summoning Scrolls?' Michael wondered.
