After entering the airship, Ben created 7 clones and started exploring it. He didn't explore it thoroughly in the past because his only goal was to spy on Grimoire Heart's forces and destroy the airship. But now, he needs to get everything from here, especially the book on Fire God Slayer Magic.
"They have restored many parts of the airship and it looks like it was repaired completely. I guess Rustyrose used Arc of Embodiment to recreate all the broken parts. But it doesn't seem he knows how the airship works so it still can't be used because the mechanical parts haven't been restored completely." Ben said as he walked around the ship.
Ben and his clones search the airship thoroughly because Hades must've hidden the magic book in a very secure place. The location won't be found by normal means so he needed to be very thorough with his search. Well, it will just be a matter of time before Ben finds it.
But the search turned out to be more difficult than he thought. Ben and his clones can't find a clue for hours even after the sky became dark. Hades was very meticulous in hiding his precious items because not one clue can be found.
Now Ben regretted killing the Grimoire Heart mages. He could've asked them a few questions although he doubts they know anything. Hades isn't stupid enough to share his secret with the Grimoire Heart mages even if he trusts them.
Ben exited the airship to get some fresh air and think clearly. He looked at the corpses of the lesser members that were scattered all over the place and the burnt corpses of the 4 he killed with Heat World.
"Damn, the corpses are starting to stink. I can't breathe fresh air like this." Ben said as a fireball formed on his right hand.
Ben shot fireballs at the corpses and burned them to ashes. This way the corpses won't rot and the rotten smell will disappear. Now he can finally breathe some fresh air and gaze at the bright moon.
As he gazed at the moon, Ben suddenly remembered something, Hades' Devil's Heart. It was the device that gave Hades a lot of power be it physical or magical. Ben destroyed it but the generator where the heart was placed is still in the airship.
Ben got an idea and stepped inside the airship again to find the generator. He found it easily because he knew exactly where it was and he saw it the last time he explored it. He just didn't search it thoroughly because it's not functioning.
"This device was connected to Hades at all times when he was alive, right? It might contain a clue to find out where he hid all his treasures." Ben said as he approached the generator.
Without the Devil's Heart installed on it, the generator is not working. But Ben had good experiences with magic items. He even had A.I Chip, a supercomputer with the ability to hack even magic.
Ben put his left hand on where the Devil's Heart was located and poured his magic power into it. His magic power immediately flowed into the circuits. A.I Chip immediately worked to detect anything that Ben's magic power touched.
[Scanning Devil's Heart generator!]
The structure of the Devil's Heart generator is being drawn by A.I Chip. Some magic defense systems that were installed also get hacked quickly and were deactivated. Ben just needed to follow A.I Chip's instructions to break the defenses.
But the generator had too many systems in it and needed a lot of magic power. Fortunately, Ben had enough magic power to supply the generator until he breached all the systems. Now the generator has accepted him as it's new owner.
"So he kept it there, huh? That's very smart, Hades." Ben said as he did something with the generator.
Suddenly, a small square spatial hole appeared in front of the generator. Ben touched it and poured his magic power into it. Again, he reclaimed it's ownership like what he did with the generator and it was successful.
But then he poured more magic power into it and many items fall to the floor. It's a subspace to store them like Ben's spatial storage. But it is connected with the Devil's Heart generator and needs a lot of power to be opened.
"Hmm, I want to say Hades is smart to be able to make spatial storage, but it's just a relic from the past. Regardless I can study it to improve my spatial storage." Ben said as he held a black cube with runes engraved on it.
Ben then checked the items that fell on the floor. There are some precious magic items and ingredients but he really didn't care about those. He was only concerned with the magic books, particularly the one on Fire God Slayer Magic.
"Nice, now I can begin the research on creating Sun God Slayer Magic." Ben said as he held the thick black book which was the book on Fire God Slayer Magic.
He doesn't immediately open and read it but he stored it in his spatial storage mark along with the other items. He will study them later because it will take time and he has a job to do now. So he left the island and went back to the mainland.
Ben immediately went to the job location to avoid wasting time. His job is to clear a lacrima crystal mine that had been taken over by magical creatures last month. The dense Ethernano inside the mine attracted a lot of magical creatures.
They installed numerous defense mechanisms and hired mages to defend against the attacks. It wasn't the first time a attack took place but this was the first time they failed to defend the mine because the magical creatures are strong.
There were a lot of magical creatures inside the mine and there were some rather strong ones. The boss is a strong S-Class magical creature, a basilisk. It was the main reason they failed to defend the mine.
Ben had an idea to quickly finish this job and take out most of the magical creatures at once. He went to the mine's main entrance and prepared his magic. A big bright orange magic circle appeared in front of him. Many of the magical creatures run to attack him but Ben finished preparing his magic before they got the chance to attack him.
"Sun Dragon Heat Wave!" Ben chanted.
Very hot heat energy came out of the circle. It entered the mine and hit all the magical creatures inside. All of them immediately scream and writhe in agony because of the heat that cooked their bodies.
The heat spread out all over the mine tunnels and hit all the creatures inside. It didn't take long for the heat to fill the entirety of the mine and come out from the other entrances. Everyone who came with Ben can hear the painful screams of the dying creatures inside the mine.
"Now I'm starting to feel sorry for them." A man commented while shivering.
"Why would you feel sorry for those damn things? They've killed and eaten our brethren. Their dying screams are like music to my ears now." Another man said as he clenched his fists.
They all have different feelings now but they all are still happy that the creatures inside died quickly. Ben maintained his spell for a few minutes until he can no longer sense any living creature inside. When he was done, steam came out of the mine and the people that followed him can feel the heat even from a distance.
"You guys wait here while I check the mine to see if all of the creatures are dead." Ben told the audience.
They all nod and he entered the mine by himself. This kind of heat was not a problem for him because he had high heat immunity. He just can't bear the smell of cooked magical creatures so he moved fast.
In the deepest part, Ben found the basilisk that had green and blue scales still barely alive. An S-Class magical creature can't be killed that easily. So Ben drew his sword and cut the basilisk's head off immediately before it can attack him.
"Now, how should I clean everything up?" He asked with a sigh.
