Chapter 9: The Thunder Fog Iron Backed Turtle
It has been several days since entering the Medicine Valley, and during this time, Chu Linfeng did not rush into the inner domain of the Medicine Valley prematurely. Having stayed in the Xuan Yuan Sect for seven years, he had naturally heard a lot of information about the Medicine Valley.
Among them is a saying that the inner domain of Yao Gu hides more than ten ancient-level demon beasts. If one doesn't have a cultivation base above the Earth Stage, encountering these ancient-level demon beasts will only result in death.
The demon beasts are divided into nine levels based on their actual strength. First and second-level demon beasts do not have demon cores, but only have a congenital talent, this type of demon beast is uniformly called wild demon beast, its strength is equivalent to about two heavy days of the cultivator.
Third to fifth-tier demonic beasts are also known as Hong-class demonic beasts, which have already condensed into a demonic dan and possess multiple unique innate skills. The strength of such demonic beasts is already quite formidable. Those at the third tier are still manageable, but if they reach the fifth tier, even a cultivator in the sixth realm of the Human Stage may not be able to match them.
Sixth and seventh rank demon beasts are ancient level demon beasts, most of which possess some ancient bloodline, with extremely powerful innate abilities. Non-terrestrial boundary cultivators find it difficult to contend against them. Even a human boundary ninth heaven boundary cultivator encountering an ancient level demon beast would only have the chance to escape.
As for the most powerful eighth and ninth grade demon beasts, they are called super-grade demon beasts. They have inherited the pure ancient bloodline, with innate abilities that are not inferior to those of ancient demon beasts, and are almost able to transform into human form. Once they successfully transform, they can become a sixth-level heavenly demon cultivator.
It's just that such a high-level demon beast is now extremely rare in the current cultivation world, especially in the past hundred years or so. Except for the Northern Continent where demon cultivators are thriving, this level of demon beast can no longer be found in the other continents.
In the outer realm of Yao Valley, in a dense forest, Chu Linfeng was hiding behind a boulder about two people high, staring intently at a "Calamity Flower" more than ten zhang away, as if waiting for something.
Erling flower, ranked 267th in the list of rare medicines, takes ten years to sprout, ten years to bloom and ten years to bear fruit. Its flowers are extremely beautiful and can be used as an auxiliary material for refining ordinary high-grade elixirs. Due to its unusual fragrance when bearing fruit, it easily attracts demonic beasts lurking around it, making it a rather precious plant.
Chu Linfeng had obtained the Nine You Demon King's personally transmitted alchemy techniques, and his ability to identify medicines was exceptionally outstanding. Attracted by the fragrance, he immediately recognized the origin of the "Erling Flower" and couldn't help but feel secretly delighted in his heart.
"With the rarity of 'Erling Flower', there should be a third-order demon beast guarding it nearby. It has been two days since I entered the outer domain of Yao Valley, but so far, I haven't even seen a single third-order or higher demon beast. Demon beasts below third order don't have demon cores, and hunting first and second-order demon beasts wasn't my original intention for entering Yao Valley."
Just as Chu Lianfeng was deep in thought, the "Calamity Flower" not far away suddenly withered and bore fruit at this moment, which made Chu Lianfeng's nerves tense up instantly.
Because he knew very clearly that after the "Calamity Flower" withered, within the time of one incense stick, if the fruit was not picked, it would wither and turn into useless rotten soil. If this "Evil Spirit Flower" really had a demon beast guarding it around, then now is the moment when the demon beast reveals its body to swallow the fruit.
As expected, just after the "Evil Spirit Flower" bore a bright red fruit that looked like blood, in less than a few breaths, a giant black turtle about the size of a zhang (a unit of measurement) emerged from the forest, resembling a huge millstone. What was even more astonishing was that the body of this suddenly appearing giant turtle was surrounded by electric currents as thick as thumbs.
"It's actually a Thunder Fog Iron Shell Turtle, this is going to be a bit tricky!" Chu Linfeng's eyebrows furrowed slightly as he suddenly saw the giant turtle rushing out of the forest.
This Lei Wu Tie Bei Gui, although it is a third-tier demon beast, is much more troublesome than ordinary third-tier demon beasts. Not only does it have extremely strong defensive capabilities, but it is also an extremely troublesome thunder-attribute demon beast with strength close to that of a fourth-tier demon beast. If not for its relatively slow speed, Chu Linfeng would absolutely not have hesitated to thoroughly abandon this hunt.
"If compared purely in terms of individual strength, a third-stage demonic beast should be slightly stronger than a human cultivator at the Third Heaven of the Mortal Realm. With my current strength at the peak of the Second Heaven of the Mortal Realm, I'm even more inadequate. Fortunately, I still have some spiritual symbols that I obtained from some of my senior uncles and aunts when I was in the sect, which can be used to deal with ordinary third-stage demonic beasts. However, if I were to encounter a Thundercloud Ironback Turtle, it would be a bit of a tough nut to crack..."
Give up or continue?
Chu Lin's mind quickly measured the strength comparison between himself and Lei Wu Iron Back Turtle, and finally made a decision.
The speed of the Leifeng Iron-backed Turtle was slow, but that was only relative. At this moment, this giant fellow, as big as a millstone, had already approached the fruit produced by the "Evil Spirit Flower". Its sharp beak-like mouth suddenly opened and quickly bit towards the bright red fruit that was as red as blood.
Boom
Just as the Thunder Fog Iron Turtle was about to swallow the fruit, a fireball the size of a gourd suddenly shot out from the slant and heavily smashed onto the Thunder Fog Iron Turtle's head.
Suddenly attacked, the Thunder Fog Iron Back Turtle was in pain and let out a loud roar. It quickly shrunk its head and retreated into its shell, which was as hard as gold. At the same time, three fireballs exploded and heavily hit the turtle's shell, causing sparks to fly everywhere.
"Four inferior Fireball Talismans only made this guy feel a little pain......" Thundercloud Ironback Turtle's astonishment at the strong defensive power also ignited the fierce and ruthless side of Chu Linfeng's personality.
The moment he emerged from behind the giant rock, he threw out a handful of ordinary spirit symbols, including the fire-attribute "Fireball Symbol", the wood-attribute "Entanglement Symbol", and the earth-attribute "Pierce Symbol". Under the simultaneous release of these three attribute spirit symbols, the Thundercloud Ironback Turtle was left in a sorry state.
He used over a dozen Spirit Symbols in an instant, and Chu Linfeng's already scarce True Yuan power was greatly consumed. However, this linked attack gave him a great opportunity to get close to the Thundercloud Ironback Turtle's side.
With its sturdy shell withstanding a barrage of wild bombardment, the Thunderback Turtle was thoroughly enraged. Its body crackled with electricity, its massive head darted out like a lightning rod, and its huge mouth opened wide, spewing forth a thick, purple electric beam that shot towards Chū Linfēng at an astonishing speed.
"Jīn gāng fú."
Translation: "Diamond Seal."
The Chu Lin wind, which had been repelled just five zhang away from the iron-backed turtle's body, suddenly surged forward again. With a fierce cry, he crushed the spiritual symbol that had been clutched in his hand, and a layer of pale yellow light instantly appeared around his body.
Almost at the same time as the light shield appeared, the purple electric light had already struck, striking the defensive light shield created by the "Vajra Symbol", but it was hard to thoroughly destroy this mid-grade defensive spirit symbol's defensive light shield. However, the purple electric light also exhausted itself and failed to harm Chu Linfeng.
"There are no more spare defensive spirit symbols available, and with my current strength, it's also impossible to dodge the purple lightning shot out by the Thundercloud Ironback Turtle. I must take it down before its next shot..."
The "Golden Vajra Symbol" that was just crushed is the only medium-grade defensive spiritual symbol left to Chu Linfeng, relying on this spiritual symbol to forcibly resist a purple electric attack once, and it also allowed him to get close to the side of the Thundercloud Ironback Turtle within a few feet, but this is also the only opportunity.
At this moment, Chu Linfeng's spirit was more concentrated than ever before, his movements were swift and agile like the wind, his hands conjured up layers of shadowy illusions, and in an instant, he threw out nearly twenty attacking low-grade spiritual talismans.
Almost twenty spirit symbols exploded in the air before the Thundercloud Ironback Turtle, more than half of them being destroyed by the sudden explosion of purple electricity around its body. However, three spirit symbols still shot towards the turtle's head.
At close range, the first fireball exploded with a loud noise, followed by the second fireball exploding right on top of the Iron-Backed Turtle's head. Although the former had an extremely strong defense, it was only based on its huge turtle shell.
At close range, the two fireball symbols' attack power instantly reached its maximum, and they were scorched bright red on their heads. Under the powerful explosive force, several thick blood mouths burst open, and dark green turtle blood flowed out from them.
However, this injury was not enough to be fatal, and at this moment, the injured Leifeng Iron Back Turtle Da Zui had already opened its mouth again, and a purple electric light suddenly appeared.
"Take advantage of the current situation..."
