In the end, Billy had to use half of his mana to create that massive death trap. He thought that he would use all of it, but since his Earth magic was so powerful now, that was the result and he liked it, more or less.
When morning came, Billy was pretty tired. Not physically, but mentally since that kind of work was different than usual. Fortunately, it didn't take long for the fruits of his labor to appear.

Billy smiled in satisfaction when he saw the crows coming and he already was getting experience. The giant moles were falling to their deaths. They were probably moving too fast and they couldn't see that a death trap was waiting for them, also, Billy sealed the previous paths used by the previous ones to keep the surprise. Nevertheless, the soldiers and adventurers were waiting for the moles, but they never came. So, they began to attack the crows in earnest with their long-ranged weapons.
"Something is weird… do you think the enemy has something in store for us now?" Svan asked.
"Worry about that later, let's just kill the crows," Billy said.
Svan nodded and grabbed a throwing spear. Barbarians weren't good with bows, but with throwing spears… They were quite something. Svan threw one and that impaled three crows in a row before losing power. Those creatures may not be sturdy, but they are pretty big and with each impact, the attack would lose power. So, that attack was more potent than a cannonball.
In any case, Billy wanted to level up Destructive Aura as much as possible before he found the summoners, but in that kind of scenario, there wasn't much room for that. So, he could only be patient.
Thanks to the death trap, the number of wounded and deceased decreased a lot in the next few battles. To the point that everyone was sharing Svan's worries. They were all thinking that the enemy was trying to make them drop their guard while he prepared a bigger move. Billy wished that he could tell them what he had done, but he couldn't since it would make Felipe wary of him. Regardless, on the third day after the last fight against the giant moles, Svan was starting to think that it was time to have a chat with Felipe and convince him to attack instead of defending.
"Let's pay a visit to Felipe," Svan declared.
"Won't your words have more weight if you bring other captains with you?" Billy asked.
"Yes, but things might end in a fight if they come," Svan replied. "Most of them share our thoughts and they don't usually take no for an answer. We are losing men, even though it is better than fighting in our own territory, they are getting impatient due to the losses."
"Well, it is only natural," Billy said.
Billy and Svan headed toward the area where Galatea soldiers were resting. He didn't hear about that, but Felipe was also offering support with his healing magic there and every day. Billy assumed that he was in the same position as Ollen, but it didn't seem like he was planning world domination. In the first place, they were a peaceful bunch that preached about peace and that they shouldn't enter into conflict with others. So, that made Billy feel conflicted. Felipe was hiding a lot of things, but his actions didn't reveal a bad person under that facade of a religious leader.
"Oh? thank you for your hard work, Captain Svan," Felipe said when he saw those two approaches. "You too, sir Billy. Forgive my manners, but I am busy here."
"I am not a sir, I may have some land, but I don't have titles that make me one," Billy said. "Regardless, you don't have to stop healing the wounded to listen to us."
"Thank you for your understanding," Felipe said. "Truth to be told, the work decreased a lot lately since you arrived. Putting that aside, you want to organize a force to attack the summoner, am I correct?"
"Yes, we don't know why the enemies' monsters are coming with small numbers lately, but I think we should use this chance to attack," Svan said.
"That usually would be the right call, but what if it is something planned by the summoned to lure us out of the safety of the city?" Felipe asked.
"I don't think that is the case, since didn't hear reports of the same thing happening in other regions," Svan replied.
"True, but what if you began to face the same number of monsters as before as you advance?" Felipe asked. "Even if I agree with the plan, I can't send everyone to help. You might be ambushed, even by the crows alone. Being attacked from the sky in an open field… Even with Billy's help, he can't deal with so many enemies from all directions, am I right?"
"You are right, if the enemies come from a single direction, I might be able to do something," Billy said. " I am only human, after all. That is why we would need the support of some healers."
Billy forgot that he will have to face the giant moles again as soon as they leave the capital. While choosing another route was possible, it wouldn't help in the long run, it would only put more work in Felipe's hands.
"Despite knowing that, you still think that is a risk worth taking," Felipe said and then rubbed his chin thoughtfully. "Despite my previous words, I also think that we should end this battle as fast as possible… still, it would make things difficult for me if I were to leave the fate of this state solely in your hands. If you agree to let Beatrice lead the attack, then I will mobilize three hundred healers to help you."
