"Should I make walls or a forcefield around the house?"
Allen pondered to himself as he thought of the first line of defense that surrounded Iris and his house.
"Why not both instead?"
He answered his question as he decided to just create both a wall and forcefield around his house.
It was just a precaution of his considering the forcefield would run out of energy from its energy source while a fortified wall would last until it was destroyed.
Using his <Supreme Engineer> and <Supreme Architect>, Allen created a blueprint of a fortified wall that could even withstand the attacks of Half-Step Perfection Realm Powerhouses. And since there weren't any <Supremes> in his world that had reached that power level, he doubted if there was anyone who could destroy it other than Iris and himself.
With his <Supreme Creator>, he created a fortified wall around the area of the house that was ten meters tall. It was created out of unknown material or at least material that Allen had created himself and it was a material that didn't exist in his world. But the durability of the unknown material could withstand the attacks of a Half-Step Perfection Realm Powerhouse.
Allen didn't forget to add a movable part of the wall that acted as the entrance to the wall. It would only open when either Allen or Iris placed their hand on any part of the wall since it acted as a hand print sensor. It was thanks to Allen's <Supreme Programmer> that he could even add programming to non-digital devices.
For example, if Allen programmed a chair to move ten meters when he sat on it, it would move ten meters just like how he had programmed it without the chair needing circuits and codes. It was one of the skills of the <Supreme Programmer>.
After Allen had created the fortified wall, he proceed to create the forcefield using his <Supreme Mechanic>, <Supreme Inventor>, <Supreme Programmer>, and <Supreme Creator>.
The energy source of the forcefield was hidden inside Allen's house. He had programmed the energy source to absorb sunlight and moonlight energy to use it as energy to keep the forcefield active.
The excess absorbed energy would be stored in a battery that he had created alongside the energy source so it could be used as a backup when the forcefield couldn't restore the damaged forcefield due to lack of energy.
Similar to the fortified wall, the forcefield could withstand attacks of Half-Step Perfection Realm Powerhouses. The only difference between the fortified wall and the forcefield was that the forcefield needed the energy to maintain while the fortified wall didn't need it. But unlike the forcefield which could restore its damages using the energy within its energy source, the fortified wall couldn't mend its damages.
After noticing the weakness of the fortified wall which was the inability to mend its damaged parts, Allen used his <Supreme Programmer> to add programming to the fortified wall.
The new programming added to the fortified wall allowed the fortified wall to restore its damaged parts by absorbing the earth energy or earth mana in the surroundings specifically the ground.
Allen still wasn't satisfied with such defenses so with his <Supreme Mage>, he created a defense magic barrier that was similar to the forcefield that he had created earlier but instead of using sunlight and moonlight energy, his defense magic barrier used the surrounding mana to maintain it.
Even with that, Allen's cautious personality still didn't find such defense safe enough so with his <Supreme Cultivator> and <Supreme Array Master>, he set up a defense array which instead of using mana from the surrounding like the magic barrier, his defense array used the spiritual qi in the surroundings to maintain it.
With that many layers of defense, Allen doubted if there would be anyone who could penetrate through it considering each layer of defense could withstand the attack of a Half-Step Perfection Realm Powerhouse.
After creating those several layers of defense that ranged from a forcefield to a defense array, Allen decided to start creating the attack system now. After all, it would be pointless to create a defense system in his house without adding an attack system.
With that in mind, Allen used his <Supreme Engineer>, <Supreme Mechanic>, and <Supreme Inventor> to set up numerous turrets at the top of his wall that not only shoot plasma bullets but also shoot pressurized water and compressed air if it ever ran out of energy.
He had created those turrets to not only attack those outside the fortified wall, but could also attack those above it. So if any intruders were planning through penetrating through his house's defenses by air, they would be shot down by his turrets.
But he knew that it wasn't enough if multiple enemies were invading through both the air and land so, with that in mind, he added another attack system.
Using his <Supreme Mechanic>, <Supreme Inventor>, and <Supreme Programmer>, he created multiple turrets that hovered above the air and only slightly above his fortified wall. The purpose of creating those was to specifically attack any air units that would invade his and Iris' territory.
For all of those previous creations of his, he had used the <Supreme Creator> talent to create all those turrets out of thin air. And with his <Supreme Programmer>, he had programmed all of those turrets to absorb the surrounding forces of nature to use them as the ammunition for his turrets.
An example was that his turrets could absorb the surrounding oxygen and hydrogen and combine those two to create pressurized water bullets.
His turrets could shoot a bullet of any bullets that the AI installed in his turrets deemed as the best bullet to use against that enemy and situation. It also has an aim bot feature due to installing an AI through all of his turrets using his <Supreme Programmer> and he dared to claim that even the <Supreme Hacker> can't hack through his AI.
Not only that, his turret could shoot 1 bullet per microsecond, and 1 microsecond after that was to reload the bullets since it could only store 1 bullet. He had also added a cool-down feature that activates every 1 millisecond to prevent his turrets from overheating.
Allen nodded in satisfaction since all turrets of his have the attack power of a Highest Realm Peak Stage and the combined attack of all of his turrets could be comparable to the attack of a Half-Step Perfection Realm.
"How about I add carnivorous plants to my lawn?"
Allen pondered to himself as he thought of making good use of the land surrounding his house with his <Supreme Environmentalist>, <Supreme Botanist>, <Supreme Biologist>, <Supreme Gardener>, and <Supreme Farmer>.
