In the next two days, Zayen spent all his efforts on studying the use of the spell [Eye of Evil]. Although [Eye of Evil] did not have strong attack power as a support spell, Zayen still enjoyed it and never got tired of it.
On one hand, it was because he found this support spell to be very useful. On the other hand, he needed something to kill time. After all, the dungeon would always be behind the scenes in the entire plan, and Jenn did not want to be in the limelight.
He would rather leave these troubles to the Grey Dwarves to deal with. He did not need to worry about Cadker.
That Gray Dwarf Consul did not have the guts to find trouble with him when the humans were attacking. Otherwise, Jenn would definitely not mind causing a part of Brandon Stone City to "accidentally collapse". That way, the indestructible tortoise shell would no longer be able to function as it should.
Of course, it was undeniable that the "Book of Ten Thousand Spells" was also the reason why Jenn was attracted to it.
The passion of the players was not to be underestimated, especially when there was a reward. Soon, Jenn discovered the other two uses of the Eye of Evil.
Using the Eye of Evil, Jenn could open the map and cast the spell at any place.
In this way, he would be able to cross thousands of mountains, rivers, and layers of obstacles to clearly see everything that was happening at the place he had marked.
But unlike before, although this spell could cross the boundaries of space, it could not see through things.
Moreover, it could only see a small area, and the mana consumption was the highest among all the uses.
Under other conditions, Jenn could maintain the Eye of Evil for a minute with 50 points of mana. However, if he were to dispel the fog of war in the distance, he could only maintain the Eye of Evil for five seconds.
Moreover, the larger the range of the peep, the longer the duration, the more mana would be consumed.
It could even be said that among the three spells that Jenn had, this was the only spell that consumed more mana than it could recover.
Therefore, when using it, Zayen must firmly control the consumption of magic power.
As for the fourth use of the Eye of Evil, it was to search for all sorts of mysterious items.
Jenn discovered this function when he accidentally cast the Eye of Evil on Verna. But it wasn't surprising. Even though Jenn was a dungeon lord, ordinary magical items were meaningless to him.
The physique of the Demons ensured that even if he were naked, he would still be stronger than those who wore the Belt of Strength and Circlet of Wisdom.
Of course, the main reason was — as an unfavored son of the Demon King, Zayen did not have the extra money to buy enough magical equipment like the others to keep up appearances.
In other words, the magic weapon in his hand alone was enough to bankrupt Zayen. From the fact that he only had a thousand gold coins left when he came to the Underdark, it could be seen that Zayen's life in the Underworld was not easy.
As a Dark Elf, Verna wasn't as picky as Jenn. She invested almost all of her rewards into magical equipment and weapons. After all, in the Underdark, strength was the only bargaining chip to protect oneself.
Due to this reason, after Jenn witnessed the Dark Elf shrouded in colorful magical radiance, he finally had a direct understanding of the fourth function of the [Eye of Evil].
It was just that Zayen had no way of mixing these functions together. It was like the different search forms of a radar. There were active radar, passive radar, infrared, electromagnetic waves, and so on. You had to switch to a suitable form to be able to accurately search for what you wanted.
For example, if Jenn entered a heavily guarded place, he could activate the [Eye of Evil]'s' God View 'mode to figure out the general situation. Then, he could activate the' See-Through 'mode to figure out the tunnels and building structures. Next, he could use the' Spirit 'mode to confirm how many enemies were in the building. Finally, he could use the' Mana Exploration 'mode to search for possible hidden magical traps, equipment, and weapons. Based on the intensity of the magical radiance they emitted, he could determine how powerful they were.
But as for the last function of the [Eye of Evil], Jenn didn't have the slightest clue.
In the past two days, he had tried all possible methods, but he couldn't find any clues about the fifth function of the [Eye of Evil].
For this reason, Jenn did a lot of experiments and mastered the use and manipulation of the [Eye of Evil]. But he still didn't have any clues about the fifth function.
However, Jenn believed that there must be something he hadn't noticed. After all, the mission clearly pointed out five usages, so there must be five functions.
Jenn once suspected that the fifth function was similar to hypnosis, but after experimenting with Bianas and Verna, it didn't seem to be the case.
He also tried some other methods, but unfortunately, he hadn't succeeded so far.
In the end, Jenn decided to borrow the wisdom of others.
Upon entering the library, the first thing that came into view was the pitch-black, tall bookshelves.
They were filled with all kinds of books. They were arranged in categories and looked no different from an ordinary library.
But Jenn knew very well that the library that came with the system wasn't ordinary. Not only did it collect the knowledge of the multiverse, but it would also change according to the needs of the owner.
As long as Jenn wanted it, the book he picked up from any classified bookshelf would definitely be the one he needed the most at the moment.
After building the library, Jenn would occasionally come here in his spare time to reminisce about the stories of the world he was in.
He could even 'accidentally' flip through a few beautifully bound game magazines on the dusty bookshelves.
Just like now, Jenn knew that the once popular virtual reality technology on Earth had been put into use. The world's first holographic simulation game, 'Dragon Soul Continent', was about to hit the market.
This made him sigh at the changes in the situation occasionally. If he hadn't transmigrated, he would probably be one of the people who picked up the virtual reality helmet to fight in a brand new world.
But after that, Jenn rarely flipped through these things.
The reason was simple. When you stayed in an environment without a computer, TV, or Internet, but you read magazines that described scientific and technological innovations all day long and fantasized about them, it was simply a kind of miserable torture. Even if you really brought an Apple 9S here, it would be useless if it couldn't be charged, right?
People always had to look forward. Instead of focusing on a brand new game that he would never be able to get his hands on, it was more practical to think about how to torture these brave adventurers who came to the dungeon for fun.
Jenn picked up a book from the bookshelf and flipped through it. But soon, he threw this' Introduction to Happiness – 17 Years of Easy Slavery 'book back.
Then, he picked up another 'Pink Book Limited Edition' book and flipped through it before putting it back on the bookshelf.
It was obvious that even the library didn't know what Jenn needed, which was why there was such a messy situation.
But there must be a way.
Thinking of this, Jenn slowly walked into the depths of the library. Soon, he saw Elyse's back.
At this moment, Elyse was sitting on a chair, immersed in a thick black book in front of him. He had to admit that Elyse's enthusiasm for learning magic was the reason why Jenn was able to obtain new spells in such a short period of time.
After all, in the system, only those who stayed in the library could start their research.
Relying on her good physique as a Half-Vampire, Elyse would read in the library for a few days without eating or drinking.
Unless Jenn or Enoya called for her, she would sit there and read. Such a hardworking heroic unit moved Jenn to tears.
Compared to those idiots in the game who not only needed to eat, drink, sleep, and play well to come to the library to study for a few hours if they were in a good mood, Elyse was simply a model worker who worked hard without complaint!
"Ah, Dungeon Lord!"
Hearing footsteps, Elyse lifted her head and looked in the direction of Jenn.
When she saw Jenn, Elyse's expression changed. She put down the book in her hand and stood up respectfully.
A blush immediately appeared on the young lady's fair face.
"Excuse me, what's the matter …"
Elyse's voice was as soft as a mosquito's, but it was no wonder. She was forcefully kissed by Zayen in front of her father. After that, she was even forced to take off her clothes and return to the dungeon.
Fortunately, there were few people in the Dungeon. Though Elyse was on tenterhooks along the way, she wasn't discovered.
Even so, the agitation that Elyse suffered was not so easy to get rid of. Hence, it was normal for her to blush and lower her head in silence when she saw Jenn.
"You're still researching Mana?"
Zayen glanced at the magic book on the table, and when she heard Zayen's question, Elyse nodded imperceptibly.
"Yes, Dungeon Lord. Your library collection is very rich. It's very helpful for my Mana learning and research …"
"Is this book the same?"
At this moment, Zayen suddenly stretched out his hand and felt a palm-sized book with a yellow cover under the magic book. Upon seeing this book, Elyse's expression changed drastically.
"This … no … this …"
"It seems like there's a need to study and research."
Glancing at the nameless book on the cover, Zayen showed a half-smile and stared at Elyse in front of him.
Elyse blushed and was speechless. She was like a student who was discovered by her teacher to have hidden a comic book.
Looking at Elyse's shy expression, Zayen's heart skipped a beat. He suddenly reached out and wrapped his arm around Elyse's slender waist.
Elyse was caught off guard by Jenn's action. She screamed and leaned into Jenn's arms.
After a few moments, the two separated from each other. Elyse's bright eyes were completely shrouded in water vapor, turning hazy and blank. Only her hands that were pushing against Jenn's chest represented the little resistance of the young lady in front of him. But it was almost negligible.
This is really interesting.
Gazing at Elyse, the corners of Jenn's mouth perked up slightly, revealing a strange smile.
Under his temptation, Elyse had gradually become addicted to it. Obviously, the mark of the demon race in the depths of her heart had already taken root and sprouted. As long as he cultivated it properly, he would definitely be able to completely control Elyse's soul.
But then again, what would happen if I use the [Eye of Evil] now?
At this thought, Jenn's eyes burned with golden flames and he activated the [Eye of Evil].
Then, he widened his eyes in surprise.
This is …
Under the gaze of the [Eye of Evil], a panel emerged beside Elyse in front of him. It wasn't the information of the character attributes, but something that Jenn had never seen before.
[Elyse (Possess quality)]
[Young lady (In front of you, is still a pure and delicate flower)]
[Self-control (Even in the face of temptations, she can restrain the desires from her heart)]
[Resistance (For the young lady, you are not enough to obtain her love)]
[Dedicate herself (For a greater goal, she can sacrifice everything)]
[Feeling Acceptance (She doesn't resist the happiness from the soul and body)]
[Sensitive Physique (Even the simplest skin-to-skin contact will make her easily fall into it and be unable to extricate herself)]
Looking at this, Jenn revealed a smile.
It seemed that he had found the last function of the [Eye of Evil].
