The large mecha's leg lifted up, the group watched with wide eyes as Sarah took a step forward in the mecha. Its step shook the ground beneath its weight. Once the dust was finally shaken off it revealed the real splendour of the mech created by Dwarves.

It was created with a special alloy, only available to those of the dwarven society. Through its limbs were thick cable wires, glowing a bright blue as they transferred energy throughout the body. The engine produced energy by gathering the elemental essences in the air, condensing it and refining it to be put into use.

"Big brother! What do you I now?" Sarah asked loudly through a microphone, her voice echoed through the castle as it bounced off the walls. She was currently extremely flustered, unsure of how to proceed since she didn't understand how to use the mech.

"Just keep walking, one pedal after the other until we get outside!" Lachlan shouted, leading them through another passage which is usually used only by the Dragon King. The Dark Dragon King opened to passage permanently, it allowed for the mech to narrowly pass through and get out.

Once outside, they stood on the edge of the castle, staring at the thick forest in front of them. Lachlan turned back to look at Sarah. "Alright, Sarah! By your side, there should be a lever and a button attached to the end of the lever! Pull the lever up, then press the button! Make sure not to do it the other way around!"

If Lachlan wasn't mistaken that was how to bring out the weapon on the mech. Lachlan didn't have a clue as to how powerful it was, but now he could see it firsthand in action. Hopefully, they aren't in the blast radius.

Sarah listened to Lachlan and began fumbling around in the cockpit, she pulled the lever on her right side and the right arm lifted up. She smiled joyfully before jumping around in her chair with excitement, then looking at her Big Brother she got a thumbs up to indicate the go.

Sarah pressed the button and loud noises started being produced from the arm, her legs started to morph shape and split into two. The new back legs dug deep into the ground, then a pike came out from the mech's back and shot straight into the ground as well. The arm had finally finished changing shape, it looked akin to an arm cannon as shown in cartoons.

"Run behind the mech!" Lachlan had a bad feeling seeing how much preparation was in one use. He swiftly disappeared from his spot and appeared behind the mech. The other quickly got the memo and retreated as well. Lachlan created aa transparent but thick sheet of ice in front of them.

The blue glow that was previously transferring throughout the entire mech began to gather at the right arm, condensing more and more as it created a light beam directed to where the arm cannon is pointing. Finally, after another 5 seconds, the attack was released.

*Boom!*

A dark blue ball of energy shot out the arm cannon, its size expanded to have a radius of 6 metres. It tore through the forest like it was paper, leaving behind a trail of destruction in its wake. Even the thickest of trees were smash through without giving the energy ball any resistance.

Finally, after tearing through so much of the forest it reached the ocean and glided across its surface. Creating a tide similar to a speedboat. It kept going forward until the group was no longer able to see it. Then, after another minute a sound echoed through the island and shook it to its core.

A large mushroom of matte black smoke could be seen in the distance, a pillar of water burst upwards along with the explosion. The group's eyes constricted as Phoebe summoned Faith; seeing the situation Faith didn't even need to be told to use his special ability. Creating a dome-like shield around them.

A tsunami towered over the dome, to the point where it left the island submerged underwater. Fortunately, the protective dome wasn't so weak and was large enough to protect all the important parts of the island. Including the farm inside the mountain.

After a minute or so the water began to return to its usual peaceful state, returning to how it was before the attack. Sarah sat in the mech motionless with wide eyes, her hands slightly shaking as she released her grip from the lever. The group behind her also stared at the damage.

Most of the island was thoroughly destroyed, and the higher parts of the mountain which were above Faith's protective dome had already eroded. The threes, torn from the ground were smashed all across the island. A few aquatic beasts left by the ocean waters laid on the ground.

Some of them that had limbs swiftly made their way back to the ocean while those that were limbless were left to die. Some of those limbless ones were fortunate enough to land in the stream, but not all of them were as fortunate as those.

Lachlan quickly hopped into the mech and released Sarah from it, holding her in one arm he jumped back down. "Are you alright Sarah? That attack didn't do anything to your body did it?" Lachlan was frantically glossing over Sarah's body.

Sarah, slightly embarrassed by what Lachlan was doing pushed his head away. "Don't worry big brother, I'm completely fine." Sarah used her adorable voice to calm Lachlan's worries, he immediately brought her closer to his chest and hugged her tightly.

"Alright, but just remember, if you feel anything wrong don't be afraid to speak up," Lachlan whispered into Sarah's ear before bringing her onto his shoulders. Lachlan didn't want anything to happen to Sarah, he especially doesn't want anything to happen if he can clearly prevent it.

"Mm," Sarah muttered faintly as she nodded.

"Alright, so, now that we know this thing's firepower, how about we go and get Anne to start researching it?" Lachlan suggested casually with a bright and joyful smile. "Who knows, maybe Anne will figure out a way to produce more of them once we give her enough time with it."

The group nodded in agreement. Anne was certainly the most capable when it comes to technology and research in general. Just the fact that she was able to come up with a weapon that works with gravity and wind stones after a few weeks to months. Who knows what she could come up with if they were to leave her researching the mech for half a year, maybe even a full year?

Walking back through the portal Anne was already standing there at the cave entrance, she was eagerly waiting for Lachlan's return. "So, what did you find on the other side? Do you have any souvenirs to show me? Any unique metals or equipment?"

She was excited to find out about Lachlan's return as it meant that he should have returned with goodies. Anne knew Lachlan wouldn't come back with just some dragons, he should have come back with a few more things along with them.

"Sure do, take this." Lachlan reached for his neck and took off the necklace that translated languages immediately. "This is a necklace that possesses the ability to automatically translate any language spoken to the wearer. And along with this, if you go through the portal, turn to your immediate right and follow the path outside the cave, you should be able to see a castle at the bottom of the mountain."

"Now, that castle is heavily fortified with strong defences even we would have trouble breaking through with our strength. Along with that is a mech, currently located on the edge of the castle's perimeter it possesses firepower akin to a nuclear bomb without the radiation side effect," Lachlan explained as Anne's eyes grew brighter and brighter. "Aside from that, inside the castle's treasury, there are a few other precious items that possess unique properties. Now, have fun researching them."

"Oh, this is a dream come true!" Anne shouted as she flew through the cave. She felt as though her youth was coming back to her when she heard all the things she's able to research. 'If only I had some more time to research as well.'

Looking at Anne's fleeting back they noticed her suddenly vanish through the spatial gate. Lachlan clasped his hands together while Sarah held onto his head tightly. "Alright, suppose we should get back to business. We should probably begin our whole academy plan as well. Since I have a dragon that's able to control iron, we'll be able to speed up the construction process."

"Alright, I'll go get some help from the orphanage while you go to the place you want to build the academy," Chloe suggested as she walked into the orphanage.

They had been planning for the academy for a while, the only issue is the actual training facilities and rooms. Obviously, they aren't going to have it decked it with advanced technology, but nor were they going to make it out of dirt.

They needed room, they needed materials, and they needed helpers. Granted, unlike most academies which would have a focus on researching beast corpses. The academy they're planning on creating will have the purpose of training their students into strong explorers and soldiers.

That way, even if they were to leave this world either by accident through a temporary spatial gate or through death. They're confident that the graduates that'll come out of this academy will have the abilities to protect humanity from extinction, that's the goal.

That's the very least Lachlan wanted to do in his mother's name. Granted, he and his group don't plan on leaving Earth any time soon. But it's better to be prepared for a street fight than underprepared for a war. Not to mention there are likely other half breeds like Lachlan wandering the surface of the Earth. Likely all planning for the extinction of humanity and the destruction of the planet.

Lachlan isn't any justice warrior but keeping the planet he lives on safe is just basic logic. He doesn't want to see humanity disappear from Earth similarly to the humans of Aaron's planet. Even if it means getting his hands soaked in blood.
