Forest Hunting Tower, after handing in the task, Lynch obtained two hundred contribution points, and discussed with Elinda Pochier, the magic stone reward of the task, Lynch also added two low-level magic stones. After separating from the two, Lynch replaced two soul crystals, one hundred contribution points and one low-level magic stone.

100 contributions, can only replace the lowest secondary soul crystal, this soul crystal is very peculiar, emitting a faint purple light, like an amethyst, Lynch's spiritual power slightly probed in, inside is a purple crystal world, Lynch can actually see the soul floating in it.

Soul crystals, essential for alchemical wizards, are also the simplest and most convenient things to enhance soul power.

......

On the ninth floor of the Senluo Tower, Lynch locked the door and approached the alchemy laboratory, where Monica was tinkering with potions on the alchemy table behind her back.

"Soul hedron, I got it for you. Lynch said.

When Monica heard this, she walked over happily, looking at the two purple soul crystals in Lynch's hand with surprise in her eyes.

"Abundant soul power!These two secondary soul crystals are enough to extend my lifespan by two years, but my alchemy has reached a bottleneck now, and if I want to refine more advanced or complex potions, I need more soul crystals. Monica said.

The soul power required to refine more complex and advanced potions is also more powerful, and when refining potions, it is necessary to maintain a sufficient fit between soul power and medicinal materials. Lynch can't help Monica get the secret method of cultivating soul power for the time being, this thing can't be bought with money, and it can only be supported by soul crystals at present.

As he spoke, Monica sat on the bed on the side, flicked her palm, and two soul crystals floated in front of her, and then a stream of purple strange abilities slowly flowed into Monica's body, and suddenly, Monica's originally tired look slowly recovered.

When the soul hedron dried up, and then fell to the ground and shattered into powder, Monica opened her eyes.

"How?" asked Lynch.

"I feel like I'm a little stronger. Monica was delighted. Monica is now a second-level alien creature, and if she wants to advance to a higher level, there is only one way to enhance her soul power, but Monica is unwilling to suck the souls of civilians, and can only strengthen her soul power through soul crystals, but this also has an advantage, because the soul power in the soul crystal is more pure, and there are no distracting thoughts.

"But this is not a solution, you are still only in a spirit state, the alien creatures are not in this world, and the existence of the human world will slowly wear away the original memory, no matter what level of spirit body, it is only a matter of time. Lynch frowned.

After the creature dies, the spirit will be banished to the Realm of Exile, and the spirit with a strong grudge before death will be left in the human world because it refuses to be summoned, this is the alien creature. Lynch had seen in a biography of a necromancer that the necromancer had captured an alien creature and refined it into an alien doll to make it fight for himself, while also preventing the loss of the alien creature's memories and life.

This is also what Lynch has to consider, he doesn't trust Monica much, he is worried that he will raise a tiger, and Monica's power will become stronger and stronger in the future, and he must find a way to control it.

"What do you want?" Monica asked, her eyes wide open.

"It's nothing, just thinking about how I can help you get more soul crystals. Lynch said with an imperceptible smile curling into his mouth.

......

......

The next day, Lynch entered the Forest Bone Tower as usual to prepare for today's lesson, but in the past six months, Lynch has learned the entry-level course very well, and the thick notebook he is holding has a dense summary of the basic knowledge.

It's time to try more advanced knowledge, Lynch thought about speeding up and walked towards the tenth floor, the nine floors below are all entry-level classrooms in various disciplines, Lynch wore a gray robe and walked into the tenth floor [Advanced Necromancy No. 2 Teaching Hall]

The class fee for advanced classes is higher, and one low-level magic stone is required for each class.

There are not many people in the class, and there are still ten minutes before the official class, Lynch saw a familiar figure, it was Wendy, Lynch was not completely closed for half a year, he knew that Wendy was a genius in the dual departments of tectonics and necromancy, and it was natural to appear in the class of necromancy.

Wendy was still sitting in the middle position, her aura was so strong that no one around dared to sit against her, and Lynch didn't want to ask for trouble, so he sat in the first row.

Open the thick notes, the first page is written about the basics of entry-level necromancy, and the next dozens of pages are written about Lynch's understanding of introductory knowledge in the past six months.

Not long after, the instructor came. A woman in a black robe, with a bewitching appearance, and cold eyes that make people chill, Lynch knows her, her name is Vanessa, the most popular necromancer genius ten years ago, it only took seven years to step into the official wizard, and the scenery was immeasurable, and later participated in the White Tower Qualification Battle in District 53 and defeated the wizards of other associations, returned to the academy to practice and teach at the same time, preparing to wait another ten years to participate in the White Tower Qualification Battle.

Once in ten years, three years have passed now.

"The Realm of Exile, do you know that the black demons, skeletons, etc. you summon are all from the Realm of Exile, of course, necromantic summoning, according to the strength of your mental power to summon creatures also have strength and weakness, but in the advanced class I will mention a new term, which is also to lay the foundation for your future exposure to more advanced necromantic sorcery. ”

Vanessa spoke eloquently and endlessly, the Exile Domain she mentioned here, Lynch is not very unfamiliar with this, he has seen in the ancient book left by the old witch, the territory of the exile of the demon god Ite, but since Ragnarok, when the wizard era came, those ancient gods have disappeared, and no one knows where they went.

"Soul contract, this is a very complicated inscription, I will explain it to you slowly in the next lesson......

Hearing the words Soul Contract, Lynch suddenly raised his eyebrows, and he thought of the [Soul Contract: Tyrant Barazan] found in the old witch's cold ice tomb. Vanessa continued, Lynch's notes focused on the main part, and the more he listened, the more surprised he became, as if opening a new door to necromancy, and then Lynch was sure that the scroll he had obtained was the kind of necromancy that Vanessa had spoken.

One of the characteristics of this kind of sorcery is that there is no grade division, and once you learn it, you can't use the Forgetting Elixir to forget the sorcery model, and more importantly, the summoned creatures signed by the Soul Contract will slowly become stronger with your strength, which means that the summons you summoned when you were an apprentice are not at the same level as those summoned by official wizards at all.

This is the strongest type of witchcraft in necromancy, and of course it has great drawbacks, and once you sign a contract with a powerful alien creature in the Exiled Domain, there will be all kinds of unknown consequences.
