This strike, the Five Flavors Sword, could not be categorized within the Ancient Sword Dao, because the Ancient Sword Dao left no room for it; each subsequent sword strike was superior to the last. The power of the Five Flavors Sword was considerably less than Sword Nine, and certainly less than the Seven Emotions Sword, meaning it couldn't be Sword Ten, which was destined to be a world-shattering blade.

If the Ancient Sword Dao could not accommodate it, then a new Sword Dao had to be forged.

This new Sword Dao would be named the Strange and Eccentric Sword Dao.

Within it would be incorporated self-created techniques that were quite potent, though perhaps not overwhelmingly powerful.

This current sword strike, the Five Flavors Sword, would therefore be designated as the first move of the Strange and Eccentric Sword Dao.

The First Eccentric Sword, the Five Flavors Sword!

This type of eccentric Sword Dao might not yield the greatest destructive power, but it would possess peculiar, strange effects, making it impossible for opponents to defend against in the future. Moreover, the Eccentric Sword Dao did not adhere to the Ancient Sword Dao's rule that each strike must surpass the previous one; it could be stronger or weaker, entirely at the wielder's discretion. At this moment, Lu Yuan felt a wave of weakness, a weakness naturally induced by the Lord of the Chaos Demon Tongue.

It was time to deal with you, Lord of the Chaos Demon Tongue.

Lu Yuan’s entire body was ensnared by the colossal tongue, a relentless barrage of five distinct tastes assaulting him. His hands were immobilized, but with a flick of his divine sense, his immortal sword, Yang Wu, flew forth: "Wind's Sweet Sword, sever." This was a sword technique as sweet as honey, its greatest injury inflicted subtly amidst the clinging embrace. The sweetness was the most damaging aspect. With one strike, a fissure was violently cleaved into the enormous tongue.

Simultaneously, Lu Yuan burst free. Indeed, the sword technique he created had proven effective. Previously, even striking with his full magical power had failed to harm the massive tongue, but now, the sweetness of the Wind's Sweet Sword slightly overwhelmed the sweetness emanating from the Lord of the Chaos Demon Tongue—this was a realm where dominance was determined by flavor.

The Lord of the Chaos Demon Tongue immediately counter-attacked. Lu Yuan followed up with two more sword strikes in quick succession: one, the Wind's Sour Sword, and the other, the Wind's Bitter Sword. The combination of sour and bitter immediately wounded the Lord of the Chaos Demon Tongue, forcing it to recoil.

At the same time, Lu Yuan unleashed another pair of strikes with a backhand motion.

One sword was the Wind's Spicy Sword, explosively fierce, aimed at the section of the tongue near Feng Mingyi. That section of the tongue was primarily dominated by a fiery spice, unable to withstand the intensity of Lu Yuan's spicy strike; a breach was torn open. Feng Mingyi, who had been uncomfortably trapped for a long time, naturally sprang out, having also broken free.

Lu Yuan thrust his sword horizontally near Heng Zhan: the Wind's Bitter Sword. This strike was the epitome of bitterness, a lingering, clinging technique that overpowered the bitterness near Heng Zhan, creating a wound. Heng Zhan also lifted his saber and broke free.

By this point, Lu Yuan had consecutively struck five times, carving five wounds into the tongue of the Lord of the Chaos Demon Tongue, rescuing himself, Feng Mingyi, and Heng Zhan.

"Aoo!" The Lord of the Chaos Demon Tongue was finally enraged. To be wounded by such a mere mortal being—how could it not be furious? The immense demon tongue whipped around, sweeping towards Lu Yuan, Feng Mingyi, and Heng Zhan in a torrent. Simultaneously, the five flavors of sour, sweet, bitter, spicy, and salty instantly intensified by ten thousand times.

The Lord of the Chaos Demon Tongue had clearly not been utilizing its full might before, but now it unleashed everything it possessed.

In that instant, everything between heaven and earth vanished completely, leaving only the five tastes.

It seemed this world was entirely composed of flavors.

Flavor was the absolute sovereign.

Heng Zhan felt his legs turn to jelly, and even Feng Mingyi, a peak Tenth Heaven World Realm master, found his magical power extremely sluggish, entirely obstructed by the five flavors.

This was the absolute zenith of flavor!

Lu Yuan raised his hand and shouted: "First Eccentric Sword, Five Flavors Sword!" Instantly, a single sword light shot out. This strike seemed fiery, seemed bizarre, seemed sorrowfully bitter, seemed clinging and sweet; within one sword, there were five sensations, yet simultaneously, these five sensations seemed to fuse into one, transforming into a single, ordinary strike.

Hwa!

A grand contest of flavors began in that very moment.

Hwa hwa hwa hwa, it was nothing but a violent clash of flavors.

Sour, sweet, bitter, spicy, and salty flavors erupted fiercely. The intensity of the five tastes at that instant was so overwhelming that Heng Zhan and Feng Mingyi could not witness the result. Suddenly, they heard a thud, as if a heavy object had fallen to the ground. After a moment, they opened their eyes to see that a section of the tongue had landed on the floor—a massive, vermilion tongue that had been severed.

Lu Yuan pressed his advantage, unleashing another strike, still the Five Flavors Sword, which sheared off another massive section of the tongue, easily a hundred zhang long, sending it crashing to the ground. This severed piece continued to twitch after landing, its demonic consciousness still active. Meanwhile, the mind of the Lord of the Chaos Demon Tongue was struck with terror. It had existed for countless eons, knowing only the Lord of the Chaos Brainstorm in the head region; it had never known any other living beings. In this oral domain, it had always been invincible, never suffering such grievous injury. Lu Yuan had thoroughly chilled its very core, and it vaguely sensed that Lu Yuan's sword light possessed an ability to neutralize it.

It let out a sharp shriek, and tens of thousands of tongues instantly materialized.

The Lord of the Chaos Demon Tongue began to flee. This was the first time in its existence it had suffered such severe harm; losing a contest of flavor against a mere human was unacceptable. It had to escape. Its courage was never particularly great; tens of thousands of tongues stabbed towards Lu Yuan simultaneously, aiming to delay him for just a moment so it could slip away in peace.

Within the Five-Tongued Hell, if it decided to escape, recapturing it would be exceedingly difficult, for the Five-Tongued Hell was the mouth of the Chaos Civilization Beast, vast beyond imagination.

"Hey, hey, hey, hey, you almost killed the three of us, do you think leaving is that easy? And I think you've been invincible here for too long; even your escape lacks any artistic flair," Lu Yuan said, instantly teleporting close to the Lord of the Chaos Demon Tongue. He then loudly gulped down some wine: "Transforming wine into a sword, the Marvelous Spirit Wine, appear!"

Marvelous Spirit Wine was a beverage capable of increasing one's sense of taste tenfold or a hundredfold. With this enhancement, even a tiny flavor could be savored manifold times more intensely. This Spirit Wine was extremely rare.

Lu Yuan had originally intended it solely for the enjoyment of fine cuisine, but a sudden thought struck him: if this Spirit Wine could enhance the perception of taste, could it also boost the power of the Five Flavors Sword?

Gulping, half the Marvelous Spirit Wine went into his stomach, and the other half was poured onto the blade of the Yang Wu Immortal Sword. Wine as the sword, wine as the essence, wielding the sword with wine, cleaving with wine.

The sword struck!

The First Eccentric Sword, the Wine-infused Five Flavors Sword!

Almost instantaneously, a massive Five Flavors Sword light shot out. How powerful! With the Marvelous Spirit Wine as an auxiliary, it truly enhanced the effect of the Five Flavors Sword, boosting it by about three times. Lu Yuan instantly unleashed the Five Flavors Sword, and this cascade of flavor swept towards the Lord of the Chaos Demon Tongue. As the sword light passed through the Chaos Demon Tongue, it instantly cleaved it in two.

Mmm!

Thousands of zhangs of tongue were sliced into two pieces by that furiously surging sword light.

"Ah!" A strange, indescribable sound echoed throughout the Five-Tongued Hell, so potent that nearly the entire region could smell it. In that instant, the life of the Lord of the Chaos Demon Tongue reached its end.

Almost simultaneously, countless spirit stones spilled out from the corpse of the Chaos Demon Tongue, which Lu Yuan instantly noticed. The Chaos Civilization Beast had been terrifying in life, so even in death, its body continuously generated spiritual energy, condensing into dense Heavenly Grade Spirit Stones that accumulated upon the Demon Tongue Lord. Now, all these Heavenly Grade Spirit Stones had fallen out. Lu Yuan quickly scanned them with his divine sense, discovering a total of ten thousand Heavenly Grade Spirit Stones. This was a massive windfall; he had truly profited greatly from this trial in the Five-Tongued Hell. With a sweep of his hand, Lu Yuan incinerated the remaining tongue remnants left by the deceased Chaos Demon Tongue Lord. After completing these tasks, Lu Yuan returned to his original location.

Upon returning, Feng Mingyi and Heng Zhan were still there. Feng Mingyi stated, "Lu Yuan, this ground is Chaos Tongue Crystal. This is a priceless treasure. Even a tiny fragment of the Chaos Civilization Beast's tongue from ages past could be immensely beneficial to you. You saved us in the Five-Tongued Hell, and you handled everything, so you should take it."

Lu Yuan naturally did not decline. As he reached out to pick up the Chaos Tongue Crystal, he was startled by its weight. This crystal was not large, perhaps the size of a room, only about three feet wide, but its weight must have been at least a hundred thousand jin. It was incredibly heavy—and this was only a tiny piece of the tongue. Just how heavy must the entire Chaos Civilization Beast have been? It was certainly an astronomical figure.

When Lu Yuan tossed the Chaos Tongue Crystal into his Sword Space, he scanned it with his divine sense. Upon entry, he discovered that the life form contained within was flawlessly perfect. Observing it with his divine sense, he realized just how perfect it was—it was infinitely superior to his own life form.

His current life form had already achieved perfection in various stages: At the Qi Refining Stage, his Qi was consummate. At the Body Tempering Stage, his physical body was complete. At the Longevity Realm, his spirit soul was flawless. At the Great Dao Realm, his Qi, Body, and Spirit achieved perfect integration. At the Chaos Sphere Realm, his external personal space was perfected.

In every major realm, he had perfected one specific aspect of himself.

Normally, he always believed his physique to be utterly perfect.

However, upon seeing the remnants of the Civilization Lord's body within the Chaos Tongue Crystal, he realized how terribly flawed his so-called perfect body was. From the perspective of absolute perfection, he was a crawling insect on the ground, while the part of the body within the Chaos Tongue Crystal was a dragon in the heavens; the gap was that immense.

How perfect it was! Staring at the arrangement of those perfectly deceased cells, Lu Yuan became completely engrossed.

He remained lost in this obsession for an unknown period until a flash of inspiration suddenly struck his mind—it was the method to break through from the Ninth Heaven World Realm to the Tenth Heaven World Realm.

That's right, he was currently only at the Eighth Heaven World Realm. His immediate goal was to break through to the Ninth Heaven World Realm, the Unity Realm, yet inexplicably, he had now conceived the method for the Tenth Heaven World Realm.
