You have learned the skill Spiritual Core.
Spiritual Core: passively increases your mana regeneration by one point per level. Passively increases the power of your magic attacks by five percent per level. Decreases the consumption of mana by one point per level when it is used, up to half of the spell or skill. Upon defeating a foe, you can obtain a portion of their mana, starting at five points per level.
Billy blinked several times in astonishment. The skill was much better than he had expected. The last effect particularly would be awesome in long fights, and that was exactly what he was enduring right now. Now he finally could see the light at the end of the tunnel.
When the enemies of the second wave finally arrived. They saw Billy attacking them like he was a wild beast, thrusting and swinging his spear around without concern for his stamina. Billy's friends got worried since the enemies had eight more waves after that, and Billy wouldn't endure it at that pace. However, after he advanced enough to find himself in the middle of the one hundred man unit, he fired several wind spheres and knocked down dozens of those who tried to attack him. Thanks to that, his friends had an easy time defeating those and joining up with him.
"Billy, you are going too fast! You need to pace yourself," Kate said.
"It is fine, I know what I am doing," Billy said. "Focus on spreading confusion among the ranks, do that before the third wave of enemies get too close!"
Billy was as calm as ever, but it was hard to believe that he truly was acting like usual. Still, he was looking around for the most wounded enemies, and he quickly dashed to finish them off. The mana he would gain for the killing was already awesome, but he would gain even more as he made the skill level up, so Billy quickly used that mana to improve the skill. While most enemies didn't even have one hundred points of mana, even fifty points per kill were already awesome.
In any case, thanks to his eagerness, Billy and his group managed to penetrate and cause havoc on the battalion in front of him a lot faster than before. The soldiers in the third wave didn't expect that one of those five would be annihilated so fast, so they still were five hundred meters away, and they didn't even begin their march.
"Kill them all!" Marie shouted upon realizing that they had enough time to time to achieve that and then start the next battle with some room to breathe and while having some numerical advantage.
In any case, in the blink of an eye, Billy made his Spiritual Core reach level four. So, he could use his crossbow without caring about the cost as long as every shot kills an enemy. However, instead of using that already, he decided to save it for later in order to make the enemies think that they were just struggling enough and the gate was within their reach. While it would take some time, it would give him and the others the chance to annihilate all the enemy soldiers on the southern side.
Despite that, when the third wave arrived, five battalions of the second wave had already been decimated. The enemy soldiers knew that they would have a tough fight despite the numerical advantage, but even pretty far away from the walls, the defenders were doing a lot better than expected. Some of them had lost fingers, hands, and entire arms, but they still wanted to fight. Their morale was sky-high because of the two groups in front of them that were decimating soldier after soldier with speed and brutality. They were Billy's party and the guild masters. Thanks to them, the defenders looked like an army of demons who were thirsty for their blood. Despite that, the enemy soldiers couldn't retreat because they knew that there were things worse than death…
Things got complicated while they were dealing with the next five battalions. Despite seeing their allies being killed by the droves, the enemies still kept pushing forward. To the point where they immediately sent the fourth wave of enemies, even while the third one still was struggling. Thanks to that, Billy was forced to rely on his crossbow a lot sooner than he had planned.
"Hey, Sarah, did you notice?" Kate asked after she made her short spears pierce the legs of two enemies.
"Yes… Billy should have ended up running out of mana a long time ago," Sarah said. "In his place, I would have emptied my mana pool three times over."
"Well, it is Billy we are talking about, so it is hard to tell when he is serious," Lily said. "Who knows, he might have come up with something new again."
That would be a bit too much… to learn two things and probably awesome ones in two days in a row… that would make Billy quite like… Billy. After all, he was the guy who learned a lot from other tribes and came up with some awesome skills. In any case, the battle kept going, and Billy started to deal with enemies even faster than before.
The extra magic power granted by Sage's Wisdom and Spiritual Core turned his crossbow into a crazy weapon. Even when the enemy soldiers focused everything on defense, they couldn't do anything to stop it. Dodging was the only option, but even so, their speed was above the normal bolts…
After some point, the soldiers stopped trying to keep their formation and just advanced toward Billy and the guild masters' party in order to wipe them out while using their allies' bodies as shields.. They ended up causing a lot of problems to the guild masters, but that only made things easier for Billy, not to mention their allies had the chance to take a breath and then attack the enemies from the sides.
