Unlimited Power - The Arcane Path

As much as Leon wanted, he couldn't just rely on the skeletons alone. So, he asked Pedro to reunite all the people who couldn't fight but had some mana. Noticing that they had no place to run, no-one refused Leon's idea. Even kids and the elderly end becoming part of the plan. Leon took out the railgun and put some steel platform he created above the first line of defense.

"This is a railgun. Fortunately, this weapon doesn't need projectiles per se." Leon explained. "But it needs fuel. Your job is to recharge this as much as possible with your mana; please be quick; once you pour your mana, go to the end of the queue and repeated that as many times as you can. It would be a good idea to let an archer with a good aim to use it and kill those Tyrannosaurus Rex."

"I think I'm the best archer in the city..." Pedro said." You can leave that to me. But you look like you are a powerful mage, wouldn't it be better if you use that yourself?"

"Even I don't have enough mana to charge it," Leon said. "However, I won't use it because I will try to kill as many as the big guns possible before they reach the city. I don't think the skeletons can kill the bosses before the bosses kill them."

"You are going to... what?" Pedro frowned.

Even Betty and Sasha thought that was madness, but after seeing the horde of monsters up close, they knew that was something that needed to be done.

"Don't worry, I'm going alone, you don't have to risk your people," Leon said.

"No, you are not going alone," Betty said.

"Sorry, but it is our job to keep our eyes on you," Sasha added.

Leon scratched the back of his head; those were resolute in going with him. Even the usually shy and meek Sasha seemed determined about it... It was probably their way to show to Hector and Amanda how grateful they were for their help and friendship.

"All right then..." Leon sighed. "I will end up using more mana, but I guess you guys can keep the flying monsters at bay and let me concentrate on the bosses."

Without wasting time, Leon created an earth platform and flew to west alongside Betty and Sasha. After two hours, flying, they finally found the horde, if seeing then by the sides was scary, looking the beast flying toward them was bone-chilling. It looked like a tsunami of monsters… Leon couldn't even decide where he should start.

"Oh, boy…"

"Don't hesitate right now, Leon," Betty said. "That is not like you."

"Let's do our best and protect the city," Sasha said.

"… You guys are wrong; I'm not hesitating…" Leon said. "Just contemplating my imminent doom…"

The monsters were marching in unison, so Leon had no more doubts that attack had been instigated by someone. Regardless, it wasn't time to hesitate or think about it. It was time to kill some monsters. Without wasting time, Leon shot three Magma Spears and killed three Tyrannosaurus Rex. As expected, those aren't on the same level as the megalodons, so Leon decided to change his tactics a little bit and created some steel spears. However, while he was doing that, dozens of harpies and insects flew toward them.

"It is you guys turn… don't hesitate, just swing your weapons." Leon said.

Before they could say anything, Leon controlled them with Telekinesis and made them fly like bullets. Although both of them got caught by surprise by the speed, they swung their weapons and killed dozens of monsters in the blink of an eye.

"I feel sick…" Betty said after she returned. "At least warn us the next time…"

Ignoring her complaints, Leon focused on finishing his steel spears. It was a good time to learn the mana version of Regeneration, but the world wasn't so convenient, so Leon couldn't help but wait until his mana was recovered. Although Leon could only control six spears, now he had the recovery to use his mana to strengthen those spears' power and speed without holding back. Even from afar, his attacks pierced the Tyrannosaurus Rexes' skull with relative ease.

"Showing that much power, you make us look like we have been playing around in the last four years…" Betty frowned.

"Keep your mouth shut and your eyes open," Leon said. "I don't have to waste with the flying monsters. If I don't concentrate, I won't be able to attack with all my power."

"Roger," Sasha nodded.

Leon saw Sasha using a technique he had never seen before. She was shooting energy beams from her swords, and they were powerful enough to kill any of the flying monsters. Betty also didn't waste time. Throwing her knives, she hit several monsters and teleported between them before slicing their throats. They were reliable and strong, Leon forgot that because he saw them struggling with magic… but without using mana, Leon would have his ass kicked against them.

After killing a few dozen of those monsters which were supposed to be fossils, several monsters recognized the threat that Leon, Betty, and Sasha were. From a safe distance, they tried to attack them, Leon dodged most projectiles, but some of them, he ended up having to use Mana Shield to protect himself and his friends. It couldn't be helped, but Leon couldn't spend his mana and time on small fry monsters.

Then Leon had an idea when a Fireball hit his Mana Shield… if he could absorb those spells… his power output would increase many times. Leon tried to absorb those spells when they hit Mana Shield, but he failed. He also tried to use Mana-Eater and consume the mana, but he failed again.

"I guess I'm not a shonen protagonist who can learn skills in the middle of a battle…"
