Yin Yang Swimming Fish

At this moment, Gu Tianxue, who was on Lin Yi's back, recalled, "I have heard of this Gu Moche. It is said that he was the first person in the Ancient Domain to create and practice demonic arts. He plundered many Martial Family in the Ancient Domain in order to learn about their unique skills. However, because of this, after he stepped down as the Mansion Master in his later years, all the families in the Ancient Domain issued a warrant for his arrest and assassination."

"They were only hunted down after stepping down Mansion Master. Those Martial Family back then were really good at enduring hardship!"

Lin Yi asked curiously, "Did this person die or live afterward?"

Gu Tianxue shook her head and said, "The ancient books do not record whether this person is dead or alive, but based on a few scattered ancient books, I speculate that this person eventually escaped into the Far West Black Fog, evaded the pursuit of various families, and finally disappeared without a trace, never to appear in the Ancient Domain again."

The Far West Black Fog?

Lin Yi's gaze sharpened.

The Far West Black Fog, as referred to by the Ancient Domain people, is the vast black fog zone that shrouds the Apocalypse Continent.

For the people of the Ancient Domain, this place is even more terrifying than the Forbidden Land; once you enter, you basically can't get out.

Even within the Tong Pass Scripture Repository, there are very few records of the Far West Black Fog region, and the records are extremely vague, as if the Far West Black Fog were an ominous place.

Shaking his head, Lin Yi stopped thinking about it and then went to the third Stone Stele.

The Stone Stele is a bit rough, and the inscription on it looks like it was only recently carved.

Lin Yi was initially puzzled, as he had not heard of any Mansion Master or Deputy Prefect falling in Tongguan Prefecture in recent years.

Looking at the remains above, it's clear that the person in question is someone we know.

It was precisely the engraving technique of his cheap Master Wushi.

"... Wu Shi behind by Deputy Prefect Central Guard Tongguan Prefecture: A copy of the Qiankun Technique. To obtain this treasure, one must swear an oath never to be an enemy of the Ancient Domain for life..."

After reading the text, Lin Yi couldn't help but frown.

What kind of trick is his master playing?!

He was invited to the Treasure Vault to select treasures, and a brand-new copy of the treasure was specially reserved.

Needless to say, Wu Shi definitely wanted him to choose this relic.

Hey, hey, before he became a disciple he was forbidden from harming ordinary people in the Ancient Domain without cause, and now he's made another vow not to be an enemy of the Ancient Domain.

Just how afraid was his master of the possibility that one day he would stand on the opposite side of the Ancient Domain?

Lin Yi suppressed his thoughts, turned his head and asked in a deep voice, "Tianxue, what is the Qiankun Technique?"

Gu Tianxue thought for a moment and said, "The Qiankun Technique is said to be an external martial arts skill left by Gu Xianhe, the ancestor of the Gu Family. This technique is recorded in the Martial Codex and contains dozens of golden martial arts, including fist, palm, sword, finger and slash, encompassing the ultimate principles of martial arts changes. It can be used in conjunction with the 'Qiankun' Domain to unleash tremendous power."

Lin Yi understood; the Qiankun Technique was clearly an external martial art that complemented the 'Qiankun' Domain.

Having this external martial arts skill is of great significance to Lin Yi.

First, it can save time for him to deduce and create external martial arts techniques. Second, it can provide a high-level perspective and allow him to understand external martial arts techniques from the perspective of Gu Xianhe, which will greatly benefit Lin Yi's understanding of the 'Qiankun' Domain afterward.

It must be said that Wu Shi did indeed foresee that gathering Eight Laws of Qiankun would ultimately not be a problem for Lin Yi, and he also knew that Lin Yi was in dire need of external martial arts techniques that matched the 'Qiankun' Domain, so he came up with this open scheme.

Lin Yi was made to swear an oath never to be an enemy of the Ancient Domain.

But Lin Yi just doesn't like being schemed against.

Lin Yi didn't believe that the Qiankun Technique couldn't be obtained elsewhere.

"Let's go, let's continue!"

Seeing that Lin Yi was going to take her up to the eighth floor.

Gu Tianxue looked troubled and bit her lip, saying, "Husband, I can't accompany you on the way. Why don't you take me back first?"

She could clearly see that Lin Yi had already struggled a bit when carrying her across the seventh floor.

"It's alright. I'd be more worried about leaving you down there alone."

To be honest, this Treasure Vault vault felt particularly eerie, especially the old man guarding it below; Lin Yi couldn't see through his true nature at all.

Lin Yi was worried that something might happen if he let Gu Tianxue spend time with the old guard.

Carrying Gu Tianxue on his back, Lin Yi, his body transformed into fire crystals, ascended the stone steps to the eighth floor.

But standing on the eighth floor, the pressure on his physical body suddenly vanished, leaving Lin Yi somewhat dazed.

"This place is really strange..."

"Husband, look behind you."

Gu Tianxue's surprised voice came, and Lin Yi turned his head to look. He saw that there was no so-called relic on the eighth floor, but a ball of glowing matter floating in the middle of the tower.

What is this?

Lin Yi couldn't help but feel strange. This glowing object was clearly floating in the center of the tower, but he couldn't see it on the other floors.

Could it be that only by reaching the eighth level can one see this luminous substance?

At this moment, from the dark depths, the withered old guard spoke, "Congratulations, you have crossed the relics area. What lies before you is the true Tong Pass Treasury. All the treasures of Tongguan Prefecture throughout the ages are here. According to the words of Wu Shi Dai, you may choose any item."

As soon as the words were spoken, the luminous substance in the center of the tower began to churn, and a Light Screen appeared, within which countless rare treasures moved and danced.

Lin Yi's eyes lit up. In that instant, he saw at least a dozen different qualities of the Heaven and Earth Power, as well as dozens of Martial Dao Spirit Treasure and several purple and gold quality spirit stones.

Goodness, there are quite a few treasures in the Tong Pass Treasury.

"Tianxue, have you seen any treasures that would suit me?"

There were so many treasures flying like shooting stars on the Light Screen that it was dazzling.

Lin Yi Yigen couldn't recognize some of the treasures.

Gu Tianxue was also quickly identifying it. Her eyes flashed, and she quickly locked onto an object, saying, "Husband, that pen is an extremely special Spiritual Treasure, it seems to be Demigod Artifact."

Demigod Artifact?

Lin Yi was startled and a look of surprise appeared on his face.

Within the Ancient Domain, Martial Saint divided Martial Dao Spirit Treasure into three levels: ordinary Martial Dao Spirit Treasure, Martial Dao Heavy Treasure (single Tongguan Treasure), and Demigod Artifact.

Clearly, the brush that Gu Tianxue saw was even more precious than a single Tongguan Treasure.

What is the origin of this pen?

Gu Tianxue, as expected of the knowledgeable person in the Ancient Domain, quickly explained, "This treasure is called the Wolf Hair Brush. It is Demigod Artifact inherited by the Ma Family. The Ma Family family has wiped out more than 10,000 people in the Ancient Domain. Their family is skilled in the first-class ' Virtual-Real ' Domain. They can turn the illusory into the real and the inanimate into the living. It is said that holding the Wolf Hair Brush means mastering half of the ' Virtual-Real ' Dao."

Got it!

Simply put, this Demigod Artifact called the Wolf Hair Brush can turn Void into reality.

Unfortunately, although this Demigod Artifact is good, it is not compatible with Lin Yi's current Domain and methods, and can only have an auxiliary effect at most.

"Let's see if there are any other treasures."

"Um."

Gu Tianxue searched the Light Screen again and quickly found another item.

"My lord, that Galaxy State Diagram also seems to be a great treasure. It is a treasure of the Tai Shang Family, containing Mustard Seed Space that can store living things."

"It's a waste of money, I don't want it."

Lin Yi possesses a Small World within him, and he looks down on the so-called Mustard Seed Space.

"My lord, I see a scroll, which seems to be the root map of the second-rate Domain ' Flame Blade,' the inherited Domain of the defeated martial arts family, the He Family..."

"No, I don't want that either."

Nowadays, apart from the missing ' Kun Earth ' and ' Dui Marsh ' Domain secret technique, Lin Yi doesn't care about any other Domain secret technique.

Gu Tianxue was still choosing, while Lin Yi was sensing more than a dozen portions of the power of heaven and earth in the Light Screen.

After refining three portions of the power of heaven and earth and quickly perfecting the ' Li Fire ' Domain, Lin Yi deeply understood the wonders of the power of heaven and earth.

If there are no treasures he really likes in this Treasure Vault, then he plans to settle for second best and choose a piece of Heaven and Earth Power that is compatible with the Eight Laws of Qiankun Domain to refine.

However, the celestial and terrestrial energies that Wu Shi threw here are all unorthodox and of low quality.

Lin Yi really didn't think much of it.

But at that moment, a primordial force of Yin Yang Two Colors, intertwined, shot rapidly through Lin Yi's eyes.

The forces of heaven and earth are like two swimming fish, one black and one white, intertwined and swimming together.

"The power of heaven and earth related to Yin and Yin-Yang!"

Lin Yi's eyes lit up instantly.

It should be understood that ' Yin-Yang ' is a highly accomplished Domain that surpasses even the first-rate level and is on par with 'Qian Kun'.

If classified by Domain grade, this kind of Heaven and Earth power can be called a Great Perfection quality Heaven and Earth power, which is far rarer than first-class Heaven and Earth power.

Even if Lin Yi doesn't comprehend the ' Yin-Yang ' Domain for the time being, this item will still be extremely useful, whether he lends it to Gu Tianxue or comprehends the ' Yin-Yang ' Domain later.

Lin Yi stretched out his hands, trying to capture the Yin Yang Swimming Fish, but the creature was full of spirituality and kept swimming around in the void of the Light Screen, trying to avoid Lin Yi's capture.

"Husband, have you chosen your treasure?"

"Okay, let's take this one."

Lin Yi nodded. He had browsed through all the treasures in the Light Screen. Apart from the Demigod Artifact Wolf Hair Brush at the beginning, none of the others were as valuable as this Yin Yang Swimming Fish.

However, the Wolf Hair Brush has limited uses; it's not a powerful, Demigod Artifact, so it's not of much help to Lin Yi at this point.

"Okay, then I'll help you."

Gu Tianxue also helped Lin Yi capture the Yin Yang Swimming Fish in the Light Screen, but perhaps because he possessed the Yin- Yin Yang Dao Body, the Yin Yang Swimming Fish flew out of the Light Screen with a whoosh and landed in Gu Tianxue's hand.

Seeing this scene, Lin Yi shook his head helplessly.

After becoming Martial Saint, Gu Tianxue had heard about the mysteries of the power of heaven and earth within her family, but she had not yet personally experienced it. She only felt that the Yin Yang Swimming Fish emitted an aura of Extreme Yin and Extreme Yang, which made her Qi-Blood and qi flow smoothly and made her feel extremely comfortable.

Although reluctant, Gu Tianxue still handed the Yin Yang Swimming Fish to Lin Yi.

"Husband, here, for you..."

However, the moment the Yin Yang Swimming Fish touched Lin Yi's large hand, it suddenly trembled, transforming into Yin Yang Two Colors, and burrowed into Gu Tianxue's sleeve, refusing to come out.

Lin Yi twitched the corner of his mouth.

This thing has such a strong spirituality; it seems to be very repulsed by him.

But in that brief moment of contact, he also used the System to read the introduction of this Yin Yang Swimming Fish.

[Yin Yang energy - Red]: A supreme treasure of heaven and earth, unique in the world. It is the power of heaven and earth born in the world due to a chance encounter. One is Extreme Yin energy, which transforms into a yin fish, and the other is Extreme Yang energy, which transforms into a yang fish. It can be refined and comprehended, and can also be used to forge strange objects. Its wonderful uses are endless.

Indeed, this perfected power of heaven and earth is of Red Grade.
