Mu Lian was stunned for a moment, obviously he didn't expect Zhu Jiu to suddenly want to practice, and after reacting, he quickly asked people to lead Zhu Jiu to a quiet room where he could practice.

Zhu Jiu followed behind a servant, and after a while, he came to a retreat room in the tower.

This ashram is located on the upper floors of the tower, and the interior layout is simple and elegant, with two tones of white and sea blue, which makes people feel at peace in their hearts, and is indeed a place conducive to cultivation.

There is a simple white futon in the center of the room, Zhu Jiu released the ghost python to be in charge of vigilance, and then sat on the futon and practiced with his eyes closed.

At this time, the light in the sea of consciousness was dazzling, and the earth vein spirit map projected by the Ten Thousand Souls Heavenly List was rapidly soaring.

It seems that because when you reach the core of the city, the distance from the leyline map in the city has become closer, so the traction has increased greatly, and the speed of rubbing has suddenly increased wildly.

With the Demon Sea Demon City as the core, the image transmitted by the spirit map spreads to the surrounding area, constantly evolving and outlining countless buildings, mountains, rivers and land veins.

And on this new spiritual map, the largest area is an endless ocean, in which the sea water is blue and black, although viewed on the spiritual map, there is still a mysterious and vast aura surging.

Zhu Jiu's thoughts watched the process of the evolution and birth of mountains, rivers and seawaters, as if he was seeing the image of the first opening of heaven and earth, and knew that such an opportunity was very rare.

This kind of viewing the vision of heaven and earth, and being touched by Miaowu, is the first time to benefit the most, so when Zhu Jiu was outside the city before, he found that Bangwen was evolving geography, and immediately withdrew, not daring to stay longer, because he was afraid that he would see more at that time, and wasted a good opportunity for Miaowu to advance.

It wasn't until this time that I had the opportunity to be alone in a room, so I was relieved to sink my thoughts into the sea of knowledge and feel it carefully.

Although the geography of the mountains and rivers evolved by the Lingtu is not comparable to the evolution process of the first birth of all things in the real heaven and earth, there are other mysterious rules contained in it.

Zhu Jiumu saw the wonderful scene of the mountains and rivers being outlined, the mana around his body was lively and vibrant, and the spiritual light appeared frequently, and the sea knowledge talisman was not summoned, and took the initiative to float out of the sea of knowledge, hovering above his head, and began to swallow the pure heaven and earth vitality.

Zhu Jiu's cultivation method in this line is different, not ordinary cultivators practice one method from the beginning to the end.

The amount of heaven and earth vitality that the cultivators of their vein cultivated are closely related to the power of the magic of the sea knowledge talisman.

For example, on Zhu Jiu's talisman, several spells such as thunder, thick earth, and the mysterious power of the Death Bone Mountain are the most powerful, and they have been recognized by the rules of heaven and earth.

Therefore, in his cultivation after the fourth order, when absorbing the vitality of heaven and earth, these spells are also the easiest to resonate with the vitality of heaven and earth, and the vitality of traction and refinement is the most powerful.

And the fourth-order talisman realm of all things is extremely critical to the cultivators of the sea knowledge talisman, and there are many cultivators in the Corpse God Dao who have been stuck in this realm for many years and cannot break through.

The main reason for this is that there is almost no high-power spell recognized by heaven and earth in this realm, so it is impossible to quickly pull more heaven and earth vitality to push the talisman to accumulate mana and break through to a higher stage.

On the other hand, in the history of the practice of the Corpse God Dao, of course, there are also people who have coincidences, and there are successive spells on their talismans that have been recognized by heaven and earth, and they cooperate with each other and are extremely powerful, which is more of a curse than a blessing.

Just because the talisman is closely related to the divine soul, the carrying capacity has its upper limit, and too many powerful spells recognized by heaven and earth appear on the talisman together, it is very likely to exceed the carrying limit of the talisman, so that the talisman will crack, the divine soul will disintegrate, and the cultivator himself will die.

That's really everything, so this cultivation process really needs to be careful step by step, usually speaking, the talisman is best when it is recognized by heaven and earth with two or at most three techniques at the fourth order.

Zhu Jiu himself is a reincarnated person, so he has two souls, and the carrying capacity of his talisman is far stronger than that of ordinary cultivators.

So at this time, there are already three spells that have been recognized by heaven and earth, and the talisman still does not appear the slightest abnormality, Zhu Jiu preliminarily estimates that his talisman should have the ability to carry about five kinds of heaven and earth recognized spells, which is his natural advantage, and it is also the capital that he gradually shows out.

The reason why the fourth order of the talisman is called the realm of all things is that it is to break all things, be indestructible, and also have a certain degree of evolution of all things, describing the meaning of the changeable talisman.

At this time, the talisman hanging above Zhu Jiu's head presented many wonderful scenes, lightning flashed, thunder was agitated, this was the vision of the thunder talisman, the rolling black mist was full of dead air, this was the power of the evil bone mountain, and there was a heavy Xuanhuang airflow like the earth surging, turning into a yellow dragon, circling around the talisman, which was the traction of the Houtu Mountain.

There are many more magical powers of other spells, which are presented on the surface of the talisman and manifest in turn.

Observed from a little distance, the talisman on the top of Zhu Jiu's head is changing rapidly, and the changes are unpredictable.

The various magic patterns on the talisman representing many power systems magically rotate on the surface of the talisman, which seems to imply the indescribable truth of heaven and earth!

Among the many various techniques that manifested visions in turn, there was a golden flame pattern that was particularly eye-catching, although the aura was not the strongest.

This is the golden flame that the ghost python stripped out after devouring the corpses of the two Great Sun Heavenly City cultivators, which is the unique secret technique of the Great Sun Heavenly City, and at this time, it also formed a flame form pattern on the surface of Zhu Jiu's talisman.

The mana in the talisman is becoming more and more abundant as these visions rotate, and the spiritual map that still evolves the mountains, rivers and oceans in the sea of knowledge is also growing and complete.

The talisman and the constantly evolving complete leyline spirit map, the two promote each other and grow each other, and in the blink of an eye, the mana accumulated in the talisman has reached the critical point of the fourth-order initial grade.

In the next moment, the golden mangs on the talisman were bright, and the mana increased layer by layer, breaking through the barrier between the first and middle grades in one fell swoop, and instantly breaking through to the fourth-order middle grade realm.

Originally, hovering above Zhu Jiu's head, when it appeared, the talisman that was only the size of a meter was rapidly rising and growing, and in an instant it had changed to nearly forty meters in length, eight or nine meters wide and narrow, and the momentum was spreading, like a long river in the sky, with the power of Ling Tian, and the mana in the talisman still grew slowly after breaking through to the fourth-order middle grade, and the changes continued.

After a long while, the talisman stabilized, gradually shrinking, until it turned into a little golden mang, and returned to Zhu Jiu Zhihai in a flash.

And with the breakthrough growth of the Golden Talisman of the Sea of Knowledge, the dark talisman that has always been running silently in the Sea of Consciousness at this time suddenly appeared mysterious and obscure fluctuations, and later, after the breakthrough of the Golden Talisman, it also rose to the middle grade of the fourth order as a matter of course.

This time, because it is a breakthrough in the small stage of the same level, the Dark Talisman has not manifested too many abnormalities, but it has always been circulating on the surface of the Dark Talisman, constantly deducing the thousands of strokes that are changing, and the speed of operation has become faster.

Finally, because of the promotion of this advancement, since Zhu Jiu broke through the fourth order, a certain arcane magic method that had been deduced by the secret talisman seemed to have undergone some kind of change and became complete.

At the same time, a vague small tree pattern was newly generated on the surface of the golden rune, which represented the formation of the wood system, which initially possessed the fourth-order power and could be used in actual combat.

Zhu Jiu is not currently ready to drive this newly generated wood spell as a means of responding to the enemy, this is mainly because his combat methods are rich enough, if he is blindly greedy, every time the secret talisman deduces one more spell that can be applied, he will try to use it, and it is easy to have the embarrassment of being too many but not refined.

Although Zhu Jiu was not ready to use the new spells deduced by the secret runes, he did not prevent the secret runes from continuing to deduce, after all, every time he analyzed one more spell, he could increase the accumulation of the runes and lay a broader path for future breakthroughs.

As long as these spells are not often used and not recognized by the rules of heaven and earth, there will be no problem with the carrying capacity of the talisman, and the continuous deduction of such a sub-dark talisman will only help the golden talisman accumulate faster and increase its power.

Then the majestic rhythm of the golden talisman and the dark talisman gradually fell silent, slowly calming down, this time advancing to the last step, that is, after the mana breakthrough, with its watering to nourish the flesh.

Wisps of mana essence escaped from the talisman, and the process of changing the body's potential began.
