The three of them looked at each other, shocked, and heard Cook continue:

"Meow (Also, even if you buy a book from us, it doesn't mean that you will be able to grasp it immediately.) Books are only a medium for providing knowledge, and mastering the ability in them requires one's own cultivation and learning). ”

"Meow (We Elu Cats are very kind neutral races, and force and dominance are not our pursuits.) However, adventurers, as long as you have the same resources, you can trade with us and study in the library). ”

Hearing Cook's words, and seeing the dazzling array of books in the carriage, even Mai Jiude couldn't help but show a look of shock on her face.

Her kendo was taught by Yagyu Shin-in-ryu, one of the mainstream kendo of the Saymoto, which is well-known in the Saymoto.

But in this library, Yanagi Shin Yin Stream couldn't be on the table at all, and the related kendo cheats were idle in the far corner of the physical arts area, covered with dust.

"So...... What do you need to pay for the transaction? Money? Or ......" Lu Mingfei hesitated and asked.

"Meow (what we need is something called 'soul fire')." Cook pulled out a book from the shelf, with "A Basic Introduction to Soul Fire" written on the cover.

"Meow (Soul Fire is a magical fire elemental unit, and it is also the source of power for trains to travel through different worlds, and we Elu Cat need to add not coal, but soul fire to the train boiler.) In addition to being able to power the train, blacksmith forging requires soul fire, and the potion master also needs soul fire to refine medicine...... Almost all the work on the train is inseparable from the soul fire as a foundation). ”

"And how do we get the soul fire?" Lu Mingfei asked.

He had probably figured out that the train numbered CC0001 was not simple, it was a train capable of traveling through the heavens and all worlds.

Soul fire, on the other hand, is a hard currency here, similar to embers for the Black Soul World, coins and survey points for the Monster Hunt World, and Mora and Primordial for the Genshin Impact World.

"Meow (Soul Fire originally originated from the immortal beings of the Dragons, the Lord of Bronze and Fire.) Legend has it that it used alchemy to wage war, ransacked the nations of the earth, and used the souls of its enemies to refine the world's first soul fire, the 'Primordial Fire', and ordered its descendants to divide the flames and draw the flame element from them to increase the strength of the dragon army - in the dragon's cognition, the world is mainly divided into five elements: earth, wind, water, fire and spirit, and the primordial fire is the purest fire element. The legendary Dragon King Norton's use of the Speech Spirit Candle Dragon is essentially to detonate the ultimate fire element contained in its body, that is, the Primordial Fire, thus releasing a power sufficient to destroy the world). ”

"Meow (With the intermarriage of the dragons, the fire of the primordial fire is passed down along the bloodline, and when the dragons mate with other species, the fire is also passed on. The stronger the vitality, the more vigorous the soul fire ignited by the fire, so the soul fire is also called the fire of life and the fire of the soul). ”

"Meow (in Ailu's research, the fourth domain dragon domain is generally called the transcendent domain, and all creatures with dragon blood and perfect genes flowing in their bodies, including dragons, are called transcendental species, and crusading against transcendent species can drop soul fire, and the greater the concentration of dragon blood, the more soul fire can be dropped)."

"Meow (Defeating half-breeds and transcendental races is an important means of obtaining soul fire.) In addition, the Elu cats in the car also initiate some commissioned tasks from time to time, such as blacksmith Smith often has a demand for ore, and grocer Tred often needs someone to help him run errands to collect goods every time he arrives at a destination, and they will give soulfire as a reward). ”

As soon as the train conductor Cook's voice fell, several people were still slowly pondering the meaning of his words, when the train suddenly shook and slowly slowed down.

"What's going on?" Lu Mingfei muttered.

He saw out the window that the train was passing through an undersea tunnel, and as far as the eye could see, he could even see fish, jellyfish and coral reefs in the deep sea.

"Meow (I'm almost at my destination, Forgotten Island.) Adventurers, before I do that, I would like to make a commission for you. ）”

Cook paused: "Meow (As the chef on the train, I need a special ingredient called red fish grass.) This grass is abundant on the Forgotten Isles, and if you help me collect the red fish grass, I will give you 1 soul fire for each plant.) ”

"Okay." Jiude Mai took a sip, and when she saw the books in the library, her eyes burned, if she could exchange any of the cheats in it, she would be able to obtain far more powerful combat power than now, which was definitely a temptation for her.

Not only in the superpower area, but even the "Eight Gate Dunjia", "Ghost Shadow", "Divine Travel", and "Iron Palm Water Floating", which are slightly lower in the serial number ranking of books in the physical arts area, all have enough attraction to her and can greatly improve her combat effectiveness - in the library, the preciousness of the book serial number is flaunted, and the higher the first letter of the sequence, the higher the ranking, the more precious, for example, the serial number of "Earthburst Skystar" is "0-01".

Next to him, Lu Mingfei and Xia Mi glanced at each other and nodded.

Lu Mingfei's face was a little heavy, if the disaster of "the awakening of the dragons" mentioned by Lu Mingze was about to happen in the near future, then the only thing he could count on was to get a dungeon reward in the Nightmare World, and improve his hope of surviving in the future by constantly becoming stronger.

"Meow (Then the visit ends here, adventurers, and I hope you have a good time on your next journey.) We'll be back on our way in three days, so complete your adventure on the Forgotten Isle within three days). ”

In other words, the mission time limit is three days, seventy-two hours...... Lu Mingfei thought to himself.

At this moment, he saw that his "Cultivation Manual for the Useless" had unlocked a new page, the "Quest List Page", and the only entry said "Puzzle Solving Quest: Forgotten Island".

[Background note: In this dungeon, you will play the role of Sakura Road, a college student who has been studying in Tokyo for many years on an outlying island, and rushes back to the island to attend the funeral because he heard the bad news of his childhood sweetheart]

[Main Quest: The death of the childhood friend is not accidental, your task is to find out the cause of the death of the childhood friend and remove the threat on the island]

[Side Mission: CC0001 Conductor Cook has commissioned you to help him find a special ingredient called Red Fish Grass from the Forgotten Isle]

[Mission time: 3 days (72 hours)]

[Partner note: Your two companions will play the role of your best classmates in Tokyo and follow you back to the island to attend the funeral]

Lu Mingfei saw that the relevant information of the task had been slightly adjusted.

At this time, the train stopped at the beach by the sea, and everyone looked at each other and got off.

The sunlight illuminated the three figures, who stepped on the golden grains of sand, leaving footprints.

The view is a beautiful island, with densely populated and tourist-driven towns to the south and sparsely populated, lush forests to the north.

The trio got off at the southern beach.

As soon as I got out of the car, I heard a girl's voice in the distance: "Sakura! You're back! ”

Lu Mingfei was taken aback, a Tokyo university student named Sakura was the one he played in this copy.

Before he could react, he felt a warm and delicate body rush into his arms, and a girl with black hair and black skin, a thin waist and long legs whimpered and hugged him, especially the two slender and straight thighs, which were really imaginative.

Lu Mingfei saw a business card entry popping up on the other party: Shenoka Yuan/Xiaoyuan.

Being able to have a proprietary business card also looks like an important person.

[Character: Madoka Kamioka]

【Occupation: Amenyeo】

[Introduction: She is one of your two childhood sweethearts on the island, and she is also the sister of the dead Kamioka Sakura]

……

P.S. adds a setting. Lu Mingfei's appearance was not mentioned in the original book. But Jiang Nan said on his Weibo: "Lu Mingfei actually looks pretty good, his eyebrows are delicate, and the corners of his eyes are slightly drooping." ”
