Since the return of the hidden island, the sea talisman has always been in a very mysterious state, since the secret rune deduction imitated the wonderful rune on the netherworld decree to create an outline, the appearance of the thunder rune has been adjusted and changed according to the outline of the rune knotted by the secret rune.

In the past two months, there has been a mysterious aura drawn by the thunder talisman that is in the process of changing, and wisps of it have poured into it.

Whether it is absorbing this extremely mysterious aura, or the change process of the thunder rune itself, it is very slow, and it has been nearly two months now, and the appearance and form of the thunder rune have not yet been finalized.

But after the accumulation of these days, the changes of the thunder charm finally came to a late stage.

Several mana threads spread out on the thunder rune, and these small mana threads moved in a mysterious way according to a specific trajectory, and finally intertwined and merged into the newborn thunder rune with great precision, becoming a part of the thunder rune.

This is already the last few wisps of mana silk that is still changing, when these few wisps of mana silk finally condensed, the large outline of the newborn thunder talisman was finally complete, and instantly showed a bright silver brilliance, and then the light color gradually changed, first a deep blue, and then a faint purple meaning.

The three-color light rotates and changes, and it looks very strange.

The complete shape of the thunder rune slowly stopped, and the shape of the dark rune deduced according to the rune rubbing of the law was completely consistent, and it was not bad.

At this time, the dark rune also suddenly erupted into vague fluctuations, and the surface of the rune had not changed for two months, and the thousands of stroke symbols that had always been condensed disintegrated in an instant.

These disintegrating strokes slowly sank into the surface of the dark runes, disappearing one after another, like gentle leaves falling on the water surface one after another, causing countless ripples that intersected and collided with each other.

The surface of the dark rune was filled with a layer of black chaos that was extremely dense and completely impossible to see, and small transparent symbols flashed from time to time in the chaos.

These symbols are complex and dense, each containing its own mysterious fluctuations, and their appearance means that the ability to deduce the Secret Symbol, as well as the power of the attribute 'dark' contained in it, has increased significantly.

The reason why the dark talisman showed signs of evolution at this time was because after the corpse treasure mirror escaped into the sea of knowledge, it continued to spread the light that came down, and it was imperceptibly giving birth to and changing everything in the sea of knowledge.

The second reason is that after imitating and deducing the runes of the Yin Decree, it seems that the secret runes have penetrated a wisp of the secret of the Heavenly Dao, thus promoting its evolution.

The change of the secret talisman can be regarded as an unexpected joy, Zhu Jiu did not expect it in advance, but after thinking about it, he felt that it was reasonable.

The mysterious change of the Cipher does not seem to be something that can be done in a moment. Zhu Jiu took his thoughts away from the black chaotic tumbling dark talisman and shifted it to the nascent thunder talisman.

The new thunder talisman is a dynamic pattern of frequent thunder and lightning, this pattern has arc thunder and flashing from time to time, the whole looks like a thunder and lightning domain constructed by thunder and lightning, the background is dark like a starry sky, this is the appearance of the new thunder talisman on the rune.

Above the thunder rune pattern, there are constantly flashing lightning arcs, either blue or silver, and occasionally arcs of flashing purple light.

These arcs seem to have some kind of spiritual sense, intertwining and conjuring up various forms above the thunder rune, there are several tangled wisps entangled, the shape is like a python composed of lightning, and there is also a single arc, which jumps and stretches in mid-air, transforming into a bird-like shape.

Thousands of arcs have different forms, as if many thunder and lightning spirits are constantly emerging from the thunder runes, looking gorgeous and amazing!

The newly evolved thunder talisman seems to have become the mother of ten thousand thunders, and it is actually an electric spirit that can drive thunder and lightning to transform into an arbitrary mimic, raging and invincible, and changing endlessly.

After this thunder talisman was formed, the mysterious aura that was drawn and absorbed from the unknown place suddenly became more intense, and these vitality swarmed into the newborn thunder talisman, making the thunder and lightning energy on the thunder talisman more cheerful and dense, like a sea of thunder and lightning.

What surprised Zhu Jiu a little was that in the newborn thunder rune, the black ghostly lightning hidden in it was still missing, but what was different from the past was that there was occasionally a trace of an arc with a faint black glow flashing in the constantly jumping arc above the thunder rune.

The appearance of this black arc looks extremely slender, and it has not mimicked the appearance of any beast or bird, it is a simple arc shape, jumping in the many flashes of mimicry lightning around it, which is very different.

Zhu Jiu tried to drive this slender black arc with mana, but found that it could not be urged as smoothly as other arcs, and as soon as his consciousness got closer, the black arc would disappear instantly, sink into the thunder talisman, and it would not appear again soon after.

Zhu Jiu tried several times, but there was still no way to manipulate and urge the black arc, so he had no choice but to give up for the time being, and the idea began to linger on the entire talisman to watch.

The golden tree on the talisman and the evolving sunset were still silent, and the rest of the spell patterns were in a normal state, each pulling and absorbing the vitality of heaven and earth, pushing Zhu Jiu's mana to gradually increase.

Because of the constantly dancing and tangled arc on the newborn thunder talisman, the entire sea knowledge talisman is reflected by the light of the arc from time to time, and the surface flickers and fades with several different colors from time to time, which makes people feel dreamy when they touch it.

The advanced change of Lei Fu this time is very huge, and its power makes people look forward to it, but Zhu Jiu did not rush to try it, but continued to sit cross-legged, and his thoughts finally turned to the gate of Yin Si and began the cultivation of Yin Canon.

The purpose of Zhu Jiu's cultivation this time was to hope to cultivate the Yin Canon to the fourth level that matched his mana, but it was not so easy to really practice.

Completely different from the smoothness of the first two orders, the cultivation of the Yin Canon just breaking through the third order from the second order was extremely difficult.

Zhu Jiu tried a little, and he knew that it was too difficult for Lu Dao to cross two orders from the second order at a time and directly practice to the fourth order of the Yin Classic, so he calmed down and prepared to practice to the third order first and then consider the next step.

He was immersed in his cultivation, not aware of the passage of time, and when he felt that his preparation and accumulation were sufficient enough to try to break through the third-order Yin Canon, it had already been several months.

On this day, many anomalies suddenly appeared on the island where Zhu Jiu was in retreat, first the sky became extremely dark, as if it were night, and then black clouds appeared out of thin air from nowhere, rapidly obscuring the core of the island for several miles.

Gradually, less than half of the island was enveloped in the thicker and thicker cold mist, and when you heard it, there was a faint screaming and crying sound, the sound was extremely fierce and cold, and the listener was frightened, when the howl was low, and there was a faint whispering sound like a demon and a ghost, which was even more terrifying and frightened!

Penetrating into the cold mist, you can see a lot of yin qi condensing and transfiguration, and the demonic ghosts that appear are flying all over the sky, making various postures and movements from time to time, as if they are cheering and worshipping, and as if they are holding strange sacrifices. There are also some ghosts and ghosts who are crying and moaning, all kinds of postures are not the same, it is completely a world composed of demons and evil ghosts, joy, anger, sorrow and joy, and some ghosts fight each other, devouring each other, and the appearance is fierce.

In the center of the Yin Qi and Ghost Mist, which is more than ten miles wide, there is a low peak that is only more than 100 meters high, and Zhu Jiu is practicing in retreat for several months.
