It wasn't until the early morning of the next day that Qi Yu succeeded in carving the first medium-grade spirit stone pattern.

Qi Yu found that the inscription of this lower grade spirit stone seemed to be much simpler than that of the middle grade spirit stone, and two hours ago he could easily engrave the 'tearing rune' pattern on the lower grade spirit stone, but now that two hours had passed, he had carved a medium grade spirit stone.

In these two hours, he wasted a lot of medium-grade spirit stones.

If there is a cultivator here, seeing Qi Yu squandering the mid-grade spirit stone so much, I am afraid that he will directly scold.

Qi Yu's actions are simply 'losers'.

However, for Qi Yu, who is now the master of the Yuqing Pavilion, these medium-grade spirit stones are really nothing, no matter the advanced synthesis function of the Divine Transformation Ring in his hand, which can be called the 'anti-heaven', it is the thirty-two islands of the overseas demon cultivation realm controlled by the Yuqing Pavilion now, which can bring him great wealth every day.

Looking at the middle-grade spirit stone with wisps of golden true yuan power dancing in his hand, Qi Yu breathed a sigh of relief, "The power of this middle-grade spirit stone, I don't know how much stronger it can be than the power of the lower-grade spirit stone." ”

Suddenly, Qi Yu infused True Yuan Force to activate the 'Tearing Rune' in the middle grade spirit stone in his hand, and in an instant, he smashed down on a small hill on the desert island below, and almost instantaneously, he arrived at the location of the small mountain.

Qi Yu watched intently.

"Wow~~"

This time, Qi Yu clearly saw that the moment it hit the hill and the moment the mid-grade spirit stone exploded, a golden true yuan force suddenly began to pull, and gradually formed a tearing force, which bombarded the hill in a blink of an eye, and the entire hill was torn apart by this force, and after a loud bang, hideous ravines appeared there.

"This is the power of the 'Ripping Rune'?"

Qi Yu was surprised.

On this deserted island, Qi Yu stayed for another day and a night, during which he mastered the initial use of the 'Penetrating Rune' and the 'King Kong Rune', but due to the limited time, he could at most carve three new runes on the Zhongpin Spirit Stone.

The top-grade spirit stone seemed to be extremely restrictive, and after studying it for a long time, he couldn't engrave any of the three runes on it.

"Mosaic!"

Soon, Qi Yu shifted his gaze to the new function 'Mosaic Function' activated by the Transformation Ring.

Taking out his own top-grade spirit weapon flying sword, Qi Yu tried to inlay a medium-grade spirit stone engraved with a 'penetrating rune' in his hand on it through the 'inlay function', so that the top-grade spirit weapon flying sword had the property of 'penetrating'...... Qi Yu guessed that if his flying sword had the 'penetrating' characteristic, and he used the sword technique in the Taiyan Sword Codex, the power would definitely increase greatly.

However, when Qi Yu tentatively embedded the spirit stone in his hand on the top-grade spirit weapon flying sword, the cold voice of the God Transformation Ring came from his ears, "...... Drip...... Drip...... Mosaic function starts...... Start the setting ...... Scanning Psionic ...... Scanner ...... Drip...... Mosaic failed...... The level of the spirit crystal and the level of the spirit soldier do not match...... Drip ......"

"Failed?"

Qi Yu had a wry smile on his face, and at the same time said secretly: "The Divine Transformation Ring seems to prompt that the spirit stone in my hand does not match the level of the spirit weapon?"

Without hesitation, Qi Yu waved his hand, and there was an extra high-grade spirit weapon flying sword in his hand, but this time the inlay still failed, and the God Transformation Ring still indicated that the level of the spirit stone and the spirit weapon did not match.

There was no way, Qi Yu could only take out a medium-grade spirit weapon flying sword again and try to inlay it.

This time, with the cold voice of the Transformation Ring, Qi Yu was ecstatic, just because this time it was successfully inlaid!

Now, on the medium-grade spirit weapon flying sword in Qi Yu's hand, there is an extra groove, the groove is not big, just enough to allow the medium-grade spirit stone to fit into it perfectly, and now this medium-grade spirit weapon flying sword, centered on the medium-grade spirit stone engraved with the 'penetrating rune', extends out a faint wisp of golden true yuan power, winding around the rhythm of the medium-grade spirit weapon flying sword.

"The current medium-grade spirit weapon flying sword ......"

As soon as Qi Yu's hand moved, the medium-grade spirit weapon flying sword rushed out and swept towards a huge reef on a desert island, ready to test the current power of the flying sword.

The terrifying True Yuan Force brewed on the flying sword, but it did not cause too earth-shattering movements, and the majestic True Yuan Force that Qi Yu poured into the flying sword seemed to be condensed into a line by a wisp of power on the flying sword, directly penetrating the huge reef, leaving a deep hole in it.

"The True Yuan Power I poured into the flying sword did not deliberately use the sword technique 'Ning Yuan Sword' in the Taiyan Sword Codex...... However, there seemed to be a wisp of power on the flying sword, which was condensing my true yuan power and controlling it into a line of attack, and it directly penetrated the reef. This degree of condensation and penetration is no less than the degree of condensation of the 'Ning Yuan Sword'. ”

"If I had already cast the Ning Yuan Sword, and combined with this flying sword inlaid with the 'Penetrating Spirit Stone', the power would ......."

Qi Yu raised his hand and took back the flying sword that flew out again, this time Qi Yu deliberately cast the 'Ning Yuan Sword', and the true yuan power poured into the flying sword also became condensed, and now the flying sword in Qi Yu's hand used the Ning Yuan Sword to come out of his hand again, and the target was still where the huge reef was.

As if he wanted to verify what he had in mind, Qi Yu's flying sword was aimed at the hole he had created earlier.

"Whew!" the flying sword burst out of the air and pierced through the past.

"Poof!" there was a soft sound, and a second hole quickly appeared in the reef.

"Sure enough!" staring at the two holes of different sizes on the reef, Qi Yu's eyes lit up.

Qi Yu used his sword technique 'Ning Yuan Sword' for the second time, and with the effect of 'Penetrating Spirit Stone', the True Yuan Force was obviously more condensed, and the hole left on the huge reef was more than twice as small as the previous blow...... Obviously, the effect of this penetrating spirit stone on the medium-grade spirit weapon flying sword has been greatly improved.

He took out another high-grade spirit weapon flying sword and tested it, and Qi Yu found that if it was about penetrating attack power, the middle-grade spirit weapon flying sword inlaid with 'penetrating spirit stones' was stronger.

However, after all, the top-grade spirit weapon flying sword is of high level, and the overall power is stronger than that of the middle-grade spirit weapon flying sword, and what is lacking is only the 'penetrating' characteristic.

"Even so, if the average medium-grade spirit weapon flying sword and this medium-grade spirit weapon flying sword in my hand are compared with each other, there is a world of difference!"

Qi Yu said secretly in his heart.

The medium-grade spirit weapon flying sword inlaid with the 'penetrating spirit stone', although it is not as good as the high-grade spirit weapon flying sword in the overall strength direction, but compared with the medium-grade spirit weapon, it is much more than that.

Gradually, Qi Yu continued to make a vow, and found that the only thing that could be inlaid with the 'inlay function' of the God Ring he mastered was the spirit weapon, the middle grade spirit stone matched the middle grade spirit weapon, and the lower grade spirit stone matched the lower grade spirit weapon...... Magic weapons, even the best magic weapons, cannot be inlaid, it seems that the problem of the material level itself is too low.

"It's been two nights and one day, and it's time to go back. ”

With a sigh of relief, Qi Yu left this deserted island and headed towards the location of the Hidden Demon Island.

Now, Qi Yu's most urgent thing at the moment is to be able to inlay specific runes on the top-grade spirit stones...... Qi Yu believed that if the top-grade spirit weapon flying sword in his hand was inlaid with any kind of spirit stone engraved with three new runes, his power would be greatly increased, and his strength would be further improved.

Therefore, after returning to the Hidden Demon Island, Qi Yu began to meditate on the carvings of the high-grade spirit stone and the top-grade spirit stone.

Time flies like a white horse, and even after a whole year, rumors of the 'Hidden Pavilion' are still circulating in the overseas demon cultivation world.

The Hidden Pavilion, no one had heard of it at all, but its rise was sudden and rapid, and it directly destroyed the 'Blood Demon Sect', which was one of the three major forces in the overseas demon cultivation world, and ascended to the throne strongly.

What's even more surprising is that the Demon Xuanmen's attitude towards the Hidden Pavilion actually donated the six rich islands controlled by the Demon Xuanmen near the northwest sea of the overseas demon cultivation world to the Hidden Pavilion. For a while, rumors spread everywhere in the overseas demon cultivation world...... Some people say that the Hidden Pavilion is actually a demon cultivation sect supported by the Demon Xuanmen, and the master of the Hidden Pavilion is actually a person from the Demon Xuanmen;

All in all, the 'Hidden Pavilion' is becoming more and more unpredictable in the eyes of demon cultivators in the overseas demon cultivation world.

Overseas Demon Cultivation Realm, within a prosperous island.

A lightning-like figure suddenly swept out of the island, and in the blink of an eye, it was in the endless sea, and it was in a hurry, as if it had some scruples.

Gradually, the island was far away, and the middle-aged demon cultivator also breathed a sigh of relief, his speed slowed down a little, and as soon as he moved his hand, there was an extra crystal clear bead in his hand, which shimmered with colorful streamers in the sunlight, and this bead could be seen at a glance that it was not ordinary.

The middle-aged demon cultivator was a little excited, "Haha! That Infant Transformation Realm demon cultivator really doesn't know anything, not to mention that this spirit bead can't be detected by his spiritual sense, even my spiritual sense can't detect it in the slightest." My cultivation is now at the initial stage of entering the Void Realm, and even my spiritual sense cannot detect this spirit bead in the slightest, and the value of this spirit bead is definitely no less than that of a medium-grade spirit weapon. ”

"It's just fifty high-grade spirit stones, so I bought this spirit bead and earned it!"

"Huh?"

Suddenly, the middle-aged demon cultivator seemed to notice something, and his face changed drastically, looking in the direction of the island he had been to before.

Now, in the distance in the sky, there are two figures approaching in the air, these are two demon cultivators, although the middle-aged demon cultivator is a demon cultivator who has entered the virtual realm, but now he can't see through these two people at all...... The two demon cultivators were led by a young demon cultivator holding a folding fan, followed by an elderly demon cultivator.

The middle-aged demon cultivator could vaguely sense the horror of the elderly demon cultivator, and he was afraid in his heart, "This demon cultivator is probably at least a high-level demon cultivator who has entered the virtual realm." ”

However, the middle-aged demon cultivator's face became even more solemn when he saw the young demon cultivator quietly looking at his location from a distance, "That old demon cultivator, although his cultivation is unpredictable, I can sense it even ...... This young demon cultivator, where he stood with his whole body, it was as if he had merged with the air. ”

"Of these two, this young demon cultivator is much more terrifying!"

When the middle-aged demon cultivator saw the young demon cultivator and the old demon cultivator approaching him, they stopped in the air and stared at him quietly, their faces suddenly changed, "It's not good, these two demon cultivators are not passing by, they seem to have come for me on purpose!"

"What's going on?!"
