In fact, he didn't mind sharing the secret behind his formation with her, but he'd prefer to fetch such a secret for a much higher price.
"I hope the coming masters will have more of these crystals, and treasures," William moved through weapons brought from the outer world. He couldn't tell their rank as they were all here at the pinnacle of dark gold grade. But even with such a downgrade, they were all better than any weapon found in this world.
"I should distribute these weapons to my people only," William muttered while examining a big sword he found, "only for the selected masters, not to everyone... This sword is good!"
His eyes shone, and he wanted to test the sword for a brief moment, before saving it in his own weapon ring, "I need more weapons for my tail... I'll need a big hammer, a spear, a broadsword, and a big knife..."
William started to pick the best weapons from his outer world weapon pile. There were more than enough to arm up half of his Black Tails group to the brim. And he intended to do that before the battle.
As he sorted all this out, he started to fully make the explosive arrows. The arrows he previously made were all based on forging. But now, he was going to add alchemy to the mix.
Doing this was how truly making an explosive arrow was in the outer world. This wasn't simple, and needed lots of preparations and steps to process the materials and ores he had.
As he already sorted out the ores he'd use, he first processed the herbs and made sure they were ready. Many bottles with different colours, concentration of herbal essence, and also effects were placed carefully all around him.
And when he got done from this, he started to forge the explosive arrow heads. This was a bit tricky, as he had to melt down ores and add the herbal essence he prepared in different stages of the entire process.
This wasn't a normal procedure anymore, and he knew a single failure would result in a fierce explosion.
"You stay here," William moved out from the underground training base, "this battle won't need you."
Moore planned to come and watch, hoping to find Jenny coming through the portal at any moment. But now it was pointless for him to go there. He was extremely fragile in terms of direct combat. And being part of this battle was more as a liability not help.
William stepped out from the underground base, knowing he'd be hours late from joining the battle. And yet he wasn't bothered by that. He already taught everyone he trusted the way to control the formations, and even led a few tests before coming to his guild town.
During the way to Lara's city, William kept receiving reports from the frontline. The battle started hot as expected, with lots of masters coming out from the portal, way higher than what he initially thought.
William imagined Lingerie would come with five thousand masters, at most would bring ten thousand masters. She was supposed to go against a couple thousand masters that Sara's mother had. And yet William missed something here.
Jenny had a deep grudge against Sara's mother. On top of that, she had her family to help and save. So, when she went back to the palace, she didn't just relay the news over for nothing.
She fabricated a good story about how she escaped from the clutches of Sara's mother. And she asked for her family to get released in return for more information about Sara's mother.
Jenny exaggerated everything, made sure to make Sara's mother look as if she had an army of tens of thousands of masters, both from this world and the lower world.
Hearing this made Lingerie seek help from many more masters. The initial wave alone was formed of ten thousand masters!
It wasn't Jenny's fault to blame, as when she left, Sara's mother force was still mostly intact. She didn't witness the destruction of Sara's masters, didn't witness the flip that happened at some point.
Jenny wanted Sara's mother to suffer the worst fate regardless of anything else. And she didn't want her to escape thanks to Lingerie bringing a small army. But all that ended up in a very unexpected situation for William's side.
