…

Somehow, Billy's attack didn't hurt any of the soldiers or barbarians. However, they still got dizzy due to the constant loudness and vibration delivered by the rain of lightning bolts. When they recovered, though, they saw that more than half of the monsters had turned into dust, and the other half was paralyzed due to the area of effect attacks. Fortunately, they recovered faster than the monsters and used that golden opportunity to finish them off as quickly as possible. Some of them looked at Billy with some complicated eyes, though.

"This should have solved things here… With her magic bow and Spiritual Core, Lily shouldn't run out of mana anytime soon, Alexander is also there and while his attacks with the giant bracers can't kill more than a few monsters at a time, he can keep doing that for a while," Billy thought. "The real issue is the eastern side since the guildmasters can't use attacks that deal with many monsters at the same time. I lent them some crossbows, but they probably won't be used for long… That being said…"

Just as Billy thought, things were rather chaotic on the eastern side. The mercenaries were fighting like madmen, but they were only humans, trained to fight other humans. Still, none of them stepped back. Even when they got their limbs cut, they kept moving forward and taking down enemies until their last breath. The Galatea soldiers were trying to heal them as much as possible, but they couldn't heal severed limbs. At least not in the middle of a battlefield.

"This is getting difficult…" Gerald, after swinging his sword and splitting a forgotten warrior in two from head to toe.

"What is wrong, gramp?" Marie asked. "This much is nothing."

Marie was cutting down the monsters as if she hadn't run for a full day without stopping. Her daggers were cutting the enemy's neck so easily that it seemed that the monsters were letting her do so. However, Gerald and Gustav had noticed that she barely was using her legs to move. She didn't recover enough just by eating and drinking a little.

"It is too soon to fall behind for the next generation, Gerald," Gustav said while he looked around and saw three monsters running toward him. He split them with a single horizontal Slash.

"At least let me complain in peace…" Gerald said, and then he noticed something. A dust curtain coming from the east.

It didn't seem like an enemy, but it was extremely fast. In the end, the dust curtain reached the back of the monsters and stopped right there. It didn't take long for the pressure put by the monsters to come to a stop. Billy had predicted that Icarus would come and help the side that was having the most challenging time, and his guess was right once again.

Because of their numbers, the level of the forgotten warriors wasn't high. Billy assumed that the summoner couldn't just use the amount of mana to summon a level one or a level hundred. Since he tried to overwhelm the temple city with numbers from three directions, he paid the price and failed yet again. Despite that, many soldiers, mercenaries, and barbarians still were killed. They had lost around four hundred of the twenty-seven hundred soldiers, two hundred of the five hundred barbarians, and three hundred of the nine hundred mercenaries. Billy did his best to prevent massive casualties but still hadn't been enough.

"It seems that Galatea soldiers have too much work on their hands treating the wounded," Kate said while looking at Billy.

"That isn't something that the help of a single person can change," Billy said. "Besides, I have the feeling that the battle isn't over yet, so I want to conserve my mana."

"I know that this battle didn't last long… But do you really think that the enemy will send another attack?" Alexander asked.

"Look around, if you wanted to take down this place, right now wouldn't be the perfect moment to strike?" Billy asked.

Alexander nodded. Everyone was tired or wounded, or both. Still, he couldn't believe that the enemy still would have another card to use when he had just lost dozens of thousands of monsters. Thanks to all that fighting, everyone was getting stronger insanely fast. Still, it wasn't enough to compensate for the losses of those that died. In any case, the group decided to stay on guard, just like Billy said. He also stayed on guard, but he often watched Beatrice use her spells. Thanks to that, he finally learned the trick behind regen. Since it was the improved version of Heal, the principle was the same. He just had to use some more mana to create an extra layer on the wound. Once the first spell was used, the next would work overtime by itself. It was the same principle Billy developed to enhance weapons with elemental magic…

Regen: it grants you the power to make a target recover health over time. For one hour, the target will recover one point of health per minute. The amount will increase according to the level of the skill, and if the health of the target reaches the total before its effect is finished, it will remain active until they get wounded again.

Cost: 50 mana

Without wasting time, Billy made sure to level up that skill up to ten at least and then used it on his friends, just to be safe. The extra effect was really something else, after all. In any case, Billy thought of making the spell level up a bit more, but then he saw a sudden flash of light in the north. He didn't know what, but he knew that something big had happened… Eventually, Billy and the others saw some creatures flying toward the temple city… and Billy didn't like what he saw…
