Logan continued the onslaught. Each demon coming near him was met with a ruthless response. His whip at times got shorter, but he just needed to spill mana water around him and use his skill to absorb the mana without having to drink it. This not only saved time but also movement, as previously taking time to drink the water was dangerous.
"Come, each one of you will pay for your deeds." Logan yelled, his voice laced with Alma's power. He began singing in a low tone, a rock song while imagining the beats to the song. He wished he had brought something to deafen the sound of his terrible singing, but the noise did its job perfectly, making all those who heard it and were considered enemies go into a mindless rage.
This caused some to even go after their fellow demon companions and begin bashing eveb trees while Logan smiled at their reactions.
"Perfect, just keep coming!" Logan yelled, adding more mindless minions to his cause. Not all those present reacted as he wanted; a few seemed too strong to be affected. That's when Kai and Lisa came to help.
"Relax, Logan. Drink some mana potions; we will help with the rest," Kai said, seeing Logan heave heavily. His soaked shirt made it known just how much magic he had used.
Lisa, on the other hand, rushed towards the boy and placed her hands on his cheeks.
"You keep doing too much, rely on us a bit more," she said lovingly, while anger seeped into her watching just how spent the boy in front of her was.
Rubina wanted to rush over, but she had to keep the fire up along with Zephyr, whose winds directed the flow of smoke and flames to make large pillars and walls in an inferno that would put even Scorch to shame.
Lisa, having healed Logan, began casting her area of effect spell Holy Nova to its maximum size. The demons that were left in the battlefield were no pushovers and should be trouble even for Logan, who was already mana spent.
"Kai, keep me and Logan safe. I just need a few minutes to charge this to its limit!" Lisa asked while trying her best to concentrate on the spell.
"I will try, Ms. Lisa," Kai said, making wall after wall of earth raise up before him to shield them from the coming onslaught as well as to deter the enemy if only for a few seconds.
The demons did not take this sitting. They all grouped up to create magic barrages that would hit each stone wall. Luckily, the thick walls held on. Kai had not been idle this past month; he had trained in earnest with Chloe to strengthen himself.
Over the walls, spears of earth of various sizes shot forth in numbers. They aimed at nothing specifically, but the sheer number of them made it impossible for the demons to keep going forth without stopping to think of the consequences.
Kai unleashed everything he had. As he did not have the mana capacity of a hero, he was quickly drained of mana, only able to stand up by pure will.
"Hope this is enough… Ms. Lisa," Kai said, huffing.
"Thank you, Kai. I have finished my preparations," Lisa then created her wings just to take her high enough to go over the stone walls before releasing the Holy Nova like a volleyball that floated to the other side of the court. The small ball of radiance made the sun pale in comparison. Its powerful beam made the demons cover their eyes as it made contact with one of them, releasing its chain reaction. It not only killed all the demons around it as it expanded like an atomic bomb but also healed all that Lisa had set as an ally.
Rubina, who was on top of a griffon, was hit by the light and healed instead of killed instantly like the rest of the demons. She wondered what would have happened if Lisa saw her as an enemy and shuddered seeing the sight before her. Some of the damaged forest was healed, all but the parts that had already died.
Logan had to sit down while watching the others fight. Using the whip in the form of a plasma cutter was extremely taxing, but he also felt the strength that every kill had given him. If not for it taking three times the mana of the mana gained from kills, he wouldn't have gotten to such a state.
"Rubina? I can't see you, are you alright?" he asked, wondering if she was safe.
"No problem, Logan. I am just checking if there are any demons that survived. Luckily, the range of effect of that spell was enough to even reach me. In other words, there should be no survivors. Most of the crystals also seemed destroyed," Rubina informed from afar. She was just a little exhausted from using her flames, but looking at the rest, she was basically in perfect condition.
"Good, contact the captain from before, tell him we found the culprits from the other incident. Have them know what they were doing. They will need to start checking all their forests. I doubt we have impeded the demons' plan; this country is far too big for a few crystals to affect it," Logan said while drinking mana water, his head pulsing with pain from the lack of mana.
"Here, Lisa and Kai, take a cup. You will need to recover. We might need to stay here for the night. I doubt we can continue again as tired as we are. We will probably have to also wait for the army to come and explain things again." Logan sighed, hoping his trip would be easy but now that this was happening, he felt a little useless for not having a way to bring his most powerful beasts with him.
Lisa was not doing too badly but decided to sit beside him. She placed her hand on his cheek and used healing magic to remove the small cuts and bruises that he had gotten from stray magic spells. The only thing Logan lamented was his expensive clothes that were riddled with holes.
