Inside the tower.

Andrina and the elf girl sat cross-legged opposite each other, while Thorne guarded the two with a long sword, staring solemnly at the undead creature elf girl who was transformed into a real banshee.

The Demon Slaying Sword that he held tightly in his hand trembled slightly, as long as the banshee in front of him moved slightly, the scorching dark red blade would instantly kill her under his control.

In the dimly lit rotunda, the sorceress Andrina murmured obscurely and incomprehensibly. Within the range where she and the elf girl sat cross-legged, a looming rune formation suddenly appeared.

"Crack!"

Under the guidance of the staff in Andrina's hand, more than a dozen energy spar with strange shapes appeared on the ground, and cracks appeared at the same time, making a faint sound.

As if substantive energy aura was slowly injected into the rune formation, the looming rays of light of the formation gradually became clear and quickly shrouded the two of them.

At this moment, a golden glow suddenly appeared in Anderina's eyes, as if invisible magic energy was condensed at the top of her staff.

I saw she stretched out her staff and gently touched the elf girl's forehead. The condensed magic energy flashed and turned into a special secret magic mark, which penetrated into the elf girl's eyebrows at a very fast speed until it disappeared.

At the same time, the morbid pretty face of the elf girl immediately filled with pain, and then she held her head with both hands, as if she was trying her best to endure the damage caused by the submersion of the mark into her body.

After bursts of suppressed mourning continued for a while, a faint gray energy erupted from the elf girl's body and submerged into Andrina's body.

One after another aura spreads out...

As the rune formation looming on the ground disappeared, the suppressed mourning of the elf girl gradually disappeared, and the faint blood-red eyes slowly subsided.

"Did it work?" Noticing that the ceremony was over, Thorne asked the sorceress who was sitting cross-legged on the ground.

"Success." Andrina's face was as pale as paper, her slightly weak body leaned on Thorne's shoulder and nodded slightly to him.

Thorne looked curiously at the elf girl sitting on the ground, thought about it, frowned and said:

"Although I don't understand the master-servant contract, I think that in the process of establishing the contract with this banshee, the master should not suffer any harm, but you seem to have suffered a backlash."

"This is not a master-servant contract." Andrina regained a little strength, so she moved slightly and took a few steps forward, and said slowly:

"What I just performed was an equality contract. In addition to putting a mark that belongs to me in the depths of her soul, there is also a trace of her negative energy in my body.

Banshees are undead creatures. They do not need rest, breathing, or eating, but they need to absorb negative energy to maintain normal operation. Because of this, their bodies are always filled with negative energy, evil thoughts, and undead breath. The main cause of various sources of evil.

The elf girl's body is like a source of negative energy radiation. As long as she appears, the surrounding area will become barren until it becomes a wasteland. "

After Andrina finished speaking, she glanced at the weak elf girl, and then turned to Thorne and said, "When I signed an equality contract with her just now, there was a link that needed to keep the other party's breath in the body.

And I belong to a living body, and the wisp of negative energy just now is close to a "touch of corruption" spell, which is naturally difficult to bear.

It can be judged from this that she has wandered ignorantly and ignorantly in this tower for nearly a hundred years, and her strength has grown to an extraordinary level. The true queen of banshees. "

"Since her growth potential is so high, why did you not sign a master-servant contract with her, but choose an equal contract with a high degree of freedom, so you are not afraid of growing up and making it difficult to control."

Seeing that the danger had been lifted, Thorne put the long sword in the scabbard and looked at Anderina with doubts.

Because when he searched the hall for the property on the corpse, he found that the magic equipment left by the wizards were all damaged by the same method, which made him have to suspect that the source of all this was the elf girl who transformed into a real banshee .

After all, the physical banshee itself is an accidental product of various coincidences, but such accidents all appear in the place of death with a strong negative energy atmosphere.

Obviously, this environment does not exist in the tower.

Then, another method is for some powerful wizards to use evil transformation rituals to cast the "Awaken the Necromancer" spell, stranded their souls on the main material plane, and then consume a huge amount of elemental energy to recast their bodies.

Because of this, he suspects that the elf banshee in front of him is a premeditated derivative. Although the other party has lost all memories and has become an innocent girl, he still cannot let people relax their vigilance and guard against unknown accidents. situation occurs.

And the banshee itself is an undead creature, no matter how innocent and innocent, the evil hidden in the heart will always be awakened one day, so he persuaded Anderina to sign a master-servant contract with the banshee.

What surprised him was that the stubborn sorceress did not follow his advice completely, but chose a relatively free and equal contract, which made him a little puzzled.

"The master-servant contract itself is a very unfair contract for the servant. If the servant is willing, it would be fine, but this elf girl obviously lacks common sense. Signing a master-servant contract with her is not equal to It is to deceive the other party's pure trust in us."

Andrina shook her head slightly and explained to Thorne:

"Of course, this is just one point. The real reason is that she is an evil undead creature. If she is deceived to sign a master-servant contract with her for the convenience of control, she will become the master who controls her life and death.

When we do this, in addition to restricting the rapid growth of strength, when she understands the cause and effect of the incident as her strength increases, the evil will in her heart will slowly breed hatred and resentment, until one day she successfully counteracts her master.

The reason why I signed an equality contract with her now is mainly because of her innocent character and powerful potential. I believe that under my correct guidance and ideological indoctrination, her evil nature will gradually be replaced. "

Thorne probably understood what Andrina meant. He just wanted to take advantage of the banshee's innocence and then give him the correct guidance, but he didn't think this method really worked, so he thought for a moment, and sorted out his words to persuade her. road:

"She is an undead creature after all, and the source of her strength is the negative energy aura. Due to her accidental birth, she lost all her memories, and was trapped in the tower for nearly a hundred years, resulting in no contact with living creatures, which is why she maintains her innocence. character.

Now that she has been discovered by us, she will gradually come into contact with the evil of human nature. Under the guidance of these evil thoughts, she will also inspire the evil will hidden in the depths of your heart. At that time, you will be the first to suffer. So you are playing with fire. "

"Don't worry, this won't happen. One of our equality contracts is that we can't hurt each other, so even if that happens, it won't affect me much, and I believe that as long as we don't let She leaves the confines of the tower, and this kind of thing doesn't happen."

Andrina smiled at Thorne and gave him a reassuring look.

"I hope so." Thorne looked at the sorceress' confident smile and shrugged helplessly.

Then, he noticed the banshee sitting on the ground due to the contract. After thinking about it, he took out a black spar the size of a fingernail from the dimension bag and threw it to Andrina.

"This is a soul spar obtained when you just killed the banshee. This spar is a great tonic for the banshee. I think her physical condition is very unstable. Give it to her, it will help The body recovers quickly."

The elf girl sitting on the ground saw the soul spar in Andrina's hand, her pale red eyes lit up, and the expression was like a child seeing her favorite candy.

…

Thorne and Andrina didn't stay too much on the second floor of the tower. When Andrina told the banshee elf girl to wait for them, they immediately went to the upper floor of the tower.

The third floor of the tower belongs to the public laboratory area of ​​wizards. Although it is not as messy as the second floor, it still cannot escape the erosion of time in the passage of time.

In the third floor of the tower, apart from the mysterious runes and thick dust on the walls, as well as the pungent, musty, cold, metal and other odors in the air, the rest are researched by some wizards. experimental equipment.

Fairly well-preserved beakers, broken scales, rotting drawings, unknown herbs, scattered teeth and fangs and other oddities were haphazardly placed on tables and counters.

The two searched and found nothing except for some preserved daily necessities.

Seeing that there were no accidental guardians, after leaving a series of footprints in the thick dust, he walked from the spiral staircase to the upper floor of the tower.

The fourth floor of the tower.

When they walked out of the stairway, a new beauty came into their eyes.

In this bright and spacious hall, a magic lighting lamp the size of a basketball is embedded in the center of the ceiling, emitting a warm light like sunlight, dispelling all the darkness.

The freshness of earth and the fresh green breath of plants filled the entire hall.

"This is the planting area for wizards." After adapting to the bright light, Thorne looked at the lush green vegetation and various grass flowers around, and then glanced at the crystal ball on the ceiling and said casually:

"The basketball-sized crystal ball should be a normal temperature environment simulated by the energy of sunlight."

"Look at those three bushes that look like tigers, boars, and elephants."

Andrina's attention was attracted by the neatly built animal-shaped bushes not far away, looking at the vivid bushes, a hint of surprise flashed in her beautiful eyes, and said to Thorne.

"It's very similar, but it's too real. It looks vivid, especially the tusks of the two dead woods of the elephant and wild boar. Obviously, the gardeners who used to manage this place are not only very careful, but also cutting skills. very good."

Thorne turned his eyes away and said to the sorceress.

"However, I always feel that something is wrong." Thorne finished, a look of doubt flashed in his eyes.

"After a hundred years, the original appearance of nature can still be maintained here, and I have to sigh at the power and almightiness of the wizarding profession." Andrina couldn't help but sigh.

A hundred years?

Maintain the original appearance?

Hearing the two words Anderina sighed, Thorne's mind flashed, and he finally knew what was wrong, so he reminded her: "Be careful, there may be unknown dangers here."

"What danger?" Andrina couldn't help but wonder.

"Didn't you see it?" Thorne pointed to a few bushes that had been trimmed into animal figures and said, "A hundred years later, why do those bushes in animal shapes never seem to grow."

"What's so strange about this, after the wizard has cast a spell on the plant, it can inhibit its growth and keep it as it is." Andrina didn't care much, and felt that the other party was making too much fuss.

"Really?" Thorne shook his head slightly: "Then can you feel the breath of magic? And a spell can't last for so long."

"That's right, I'll try it." Andrina looked stunned, and then walked towards the few animal-shaped bushes.

"careful!"

When Andrina had just stepped into the ground covered with green grass, Thorne suddenly noticed the abnormality of the three bush-shaped animals he had been staring at, and immediately pulled her back.

"The moment you stepped into the grass, I noticed their subtle movements. I suspected that these three shrubs were the guards of the plantation." Noticing the suspicious gaze of the other side, Thorne said solemnly.

The guards of the plantation?

Andrina repeated it in her heart, as if she had thought of some key clues, and immediately took out a book on constructing creatures and began to read it.

After a while.

She put away the books and glanced at the distant bushes unexpectedly again, showing a sudden look: "I know what they belong to."

Noticing Thorne's gaze, Andrina continued: "They are plant guards shaped into animal shapes, not living plants that can move at will, but similar to clay golems, Belongs to the branch of constructs."

Constructs?

There was a hint of surprise in Thorne's eyes. He didn't expect that there were also plant-type constructs. The world was really big and full of wonders, which made him have to sigh in his heart that wizards are a group of all-powerful spellcasters.

Then Thorne looked at the sorceress beside him, waiting for her next introduction.

"They are powered by souls connected by magic to the Elemental Plane, and their defensive function is like a decoration. These constructs are mixed with ordinary vegetation, and only when intruders break in, they will activate the protection system.

However, since their crafting materials are mainly composed of tiny branches and leaves, these plant-like constructs are not as strong and defensive as clay golems and other golems.

But correspondingly, their speed and sensitivity have been improved a lot, which should not be a problem for you. The only thing you need to pay attention to is that they are filled with natural spells by wizards, so that they have the ability to cast spells. "
