Millennium Tension

"Wait here, we'll take care of everything."

Aizen speaks briefly to the six girls as Ana and Axel stop their attack on the ground. After the girl in the energy barrier nodded without a problem, he walked out of it by slightly opening the energy gap in the barrier and closing it again as he exited.

The area of ​​destruction was already severe, apart from the area near the energy barrier that was coiled like a ball, everything had already been ravaged by Ana and Axel's finishing attacks.

"That troublesome monster has perished?" Aizen flew towards Ana and Axel, the two of them still watching things further down.

"I'm not sure. Even though that monster and his current herd are no longer surfacing, I believe they are still hiding down there." Axel smiles at Aizen as she shakes her head.

"I was sure that all the snakes were one monster. All their actions were too organized, and it would be impossible if they were each other's existence." Ana folded her arms under her breasts as she surveyed the area of ​​destruction.

"There are only two possibilities, they are all controlled by one existence or they all come from one monster. All the monsters' bodies that appear never completely leave a hole in the ground and that's quite strange." Aizen presents his hypothetical case.

They still couldn't detect any further than two kilometers underground, and that was such a disadvantage because none of them knew what kind of monster was waiting down there, the real monster and the core.

"Axel, why haven't you launched your own attack?" Aizen asked lightly out of curiosity without any other means.

Aizen and Ana still needed advanced equipment to keep up with the enemies they faced together, but Axel was already in [Rank 9]. She aligns with Aizen and Ana who still rely heavily on technological skills even when facing this troublesome monster.

"The devastating attack of [Rank 9] is not something to be taken carelessly. I was afraid you and the six girls over there could be affected earlier. I am good at controlling energy but it is not the same when it is used for destruction techniques." Axel sighed as she also couldn't find any movement under the ground.

"Our seven servants are awakened and perfect, right? Why don't we get them to help us this time?" Ana clapped her hands at an idea that had just emerged in her head.

"That's great, I had an idea for that with seven of them with us." Aizen nods with an idea that can anticipate a destructive force of [Rank 9] or higher in this unsuitable setting.

Then Axel delivered her message to the seven servants who were still in the [Axel Goddess] to immediately prepare for battle with their complete equipment. Then the seven of them appeared around.

"We are at your service, Master and Mistresses." Seven of them placed their hands on their upper chests to salute in unison.

"I, Aizen, welcome and congratulate you on the refinement of your bodies. This time we face quite a troublesome enemy. Look at the description of the plan I just created in the system. We will act immediately." Aizen opened his arms as if in greeting and gave an order as they were still on the battlefield.

"Roger!" The seven servants known as fairies replied in unison.

"Ana, Axel, because the monster first appeared in the middle of this hall. We'll make a deep hole right in the middle there."

Aizen said while looking at the ground in the center of the hall. The hole that was there was tightly closed as if there had never been a giant hole there, while the area of ​​destruction that Ana and Axel caused was also starting to recover on its own.

Ana and Axel nodded at the plan. Then all of them, now ten of them, hovered right above the center of the hall to carry out the plan Aizen had put forward in their system.

Axel flew a little higher and the other nine people led by Aizen flew in a circular formation at a predetermined distance and created an integrated rune of focused techniques to sustain the power of Axel's destructive technique as she still could not fully control the extent of its destruction apart from total destruction.

A circular white rune appeared among the nine people and dense energy began to envelop the rune. The rune is in charge of balancing Axel's destructive techniques so that it is focused on one point and doesn't spread anywhere.

'Axel.' Aizen gave a sign that everything was ready.

Axel nodded while preparing one of her destruction techniques. The golden energy aura enveloped her body and the irises in her eyes turned to gold as a surge of energy around her seemed to signal impending doom.

Then she brushed her hand gracefully over the prepared rune just below her.

*Swoosh!* *Boom!*

The golden energy with high penetrating power was balanced by the white runes that coalesced into gold which the nine people continued to spur, the destructive technique violently smashed into the ground beneath them and bore a hole deep into it.

*Roar!*

A loud roar that sounded like a monster in pain from its agony echoed from the large hole that had just emerged from the combined technique.

It was clearly visible to their advanced naked eyes that there was a really huge round monster with many snakehead tentacles around it. It was writhing with wounds while screaming in pain from the largemouth at the center of its body.

The [Rank 9] destructive power had been drained heavily due to the penetration distance to the depths of the ground and could only injure the monster who was the main boss of this gigantic hall.

'Axel, one more time! 'Aizen exclaimed without letting the other's mind think of the strange monster down there.

Axel launched another attack that focused solely on destructive power and immediately hit the monster hard with a powerful explosion deep underground.

The main monster who was there could only scream while roaring horribly at his own destruction. Even the six girls who were taking shelter within the strong energy barrier trembled at the terrifying roar.

A slight earthquake shook the ground in the giant hall but the cause and effect seemed to be held back by something and could not creep out of the giant hall.

Aizen and eight others stopped their combined rune to take a brief look at the deep underground of the large hole that penetrated deep into the ground.

When the explosion died down, the [Rank 8 Grade 10] monster was already annihilated with a shattered body.

"Send several units to collect the remains of that strange monster's body, we will give the monster an honor to become our research material later." Aizen spoke clearly and seven servants did not take long to carry out the task.

They accessed [Space Storage] and sent many versatile units for it to move the rest of the monster's body into [Space Storage] quickly.

After everything was over and the versatile unit had returned to the [Space Storage], the shattered ground began to heal itself again until the huge hole that had been created closed again and the runes that had been spreading everywhere began to be pulled back towards the majestic gate with that oppressive aura.

Now the ground in this gigantic hall had recovered as if there had never been a battle at all and everything was back to how it was when all of them entered here for the first time a while ago.
