168,

The beautiful and powerful knight of the wind, repeatedly swinging countless wind blades, finally annihilated the Gluttony after an hour.

At the same time, the demon army, who were late to the party, finally arrived to support them.

It's possible that no one has invaded in hundreds of years, and this loose defense line is basically relying on their reputation to intimidate the enemy. It was only because of Gluttony that they were able to succeed in this surprise attack.

There were thousands of demon minions inside the tower, along with Gluttony himself as the tower master, but they couldn't stop Sonja.

However, this was just an advantage in terms of tactics. Faced with an army of fifty thousand demons coming from the Mist Poison Swamp, Sonja couldn't hold on for long no matter how strong she was.

Returning to the center of the magic circle, Sonja kneeled on the freshly drawn magic circle by Bettina.

"Sis, I'm counting on you."

"Alright."

The elves have always taken pride in their powerful forest magic.

For the elven clan, who may lack in physical strength but excel in the use of magic, building a fixed magic circle to create a defensive barrier is art.

There are pros and cons to this. This fixed defense, like death itself, is only a matter of time before it is breached.

The forest magic that is imbued with the earth element strengthens the internal structure of the tower into a forest maze.

However, this maze, which can only summon an artificial forest, twisted from the trees, can be destroyed easily with a simple fire attack.

Although it is possible to withstand the flames through stronger reinforcement, the physical confrontation is too strained. Facing an army of fifty thousand demons, Bettina and the eight mages are not enough.

But at this moment, adding Sonja would be sufficient.

If the tower is the "shell," Sonja can build a shield of wind outside of it.

Behind Sonja, saliva flows from the mouth of someone, and it's due to this dangerous task that Bettina reluctantly agreed to let Daniel assist.

Bettina sits behind Sonja and hugs her from behind.

"Hehehe~"

Making a lewd sound, Bettina finally gets to hold her beloved sister as she wished.

Her hands slowly reach for Sonja's enchanting breasts. It's so close, she could almost squeeze them.

But Sonja catches Bettina's hands and says,

"Bettina?"

Feeling Sonja's warmth, with her mouth already kissing Sonja's back, Bettina's idle obsession can no longer be hidden.

She gently bites Sonja's ear, and as Sonja relaxes her hands, Bettina succeeds in her conquest.

Gently massaging and then leaning in to kiss Sonja's neck.

"Be-Bettina?"

Although Sonja knew they would construct the barrier together, she never expected the current situation.

"Just relax a bit~ Sis, you need to relax for our barrier to merge together~"

Bettina is right. Two different people with two different types of magic, unless they are geniuses, it is extremely difficult to combine two different types of magical abilities.

Although Bettina's behavior is unnecessary, Sonja reluctantly let's Bettina take the initiative in order to better cooperate.

"Sis, you're really strong. You can easily defeat monsters like that~"

Listening to Bettina's gentle voice while relaxing her body for Bettina to freely explore, Sonja can even feel a slight dampness.

Before closing her eyes, Sonja gazes at the distant scenery outside the tower along the wall.

Following the peaks of the Cliffs of Despair, a man-made brick road leads directly to another original sin towers.

"Monsters... huh?"

There, Sonja feels that there is a true monster.

Closing her eyes, she completely relaxes her body.

Bettina hopes to maintain the position of massaging her own chest, while her neck is gently kissed.

The magic circle on the ground emits a bright green light and begins to extend countless tree vines from the circle.

Slowly wrapping around the bodies of the two beautiful girls, more and more vines intertwine, forming the heart of the forest.

With the appearance of the forest heart, the entire tower is also covered with larger and thicker tree branches, until it becomes a forest that envelops the Tower of Gluttony.
