The rune is not particularly large, but the size of the fingernail, but this small rune paper contains complex energy changes, the same rune, because of the subtle energy strength, the depth of the texture, the difference in the soul power itself, each rune mage made the rune paper is different, there are good and bad, Cang Jian doesn't know how the rune he made is, but he is satisfied.

This rune is a blood spirit rune, as long as the spiritual power is injected into the rune that activates it, countless blood spirit grass will grow in this small rune paper, blood spirit grass is one of the evil plants in the fairy spirit continent, this is a very difficult plant, extremely tough, ordinary weapons have no way to cut it off, if you don't escape in time, the flesh and blood of the whole body will be sucked by the blood spirit grass into a pile of white bones.

However, all things are mutually reinforcing, and although this blood spirit grass is difficult, it is not impossible to resolve it, that is, fire. Plants are most afraid of fire, especially the evil plant of Blood Spirit Grass, which is forced to retreat when it encounters fire. This is also the biggest weakness of the cangjian rune, if the other party is a fire attribute cultivator, then the role of this rune is not so great.

But this is not difficult to defeat Cangjian, Cangjian took out the blood of the first-level fire attribute demonic beast that he purchased before, and used half a bottle at once, Cangjian quickly sealed, this can't fail, one failure is more than a hundred taels of gold, it is enough for ordinary people to live for half a year, this is the first time Cangjian feels that he has money, more than a hundred taels of gold in a second, maybe this day after this day, the thousand taels of gold will be gone, just like playing with money.

But under the effect of soul power, the fiery red blood was integrated into the rune, which was the method of ascension, and after being integrated into the blood, the rune on the rune paper also changed, and it was originally just scarlet with a trace of firelight, which looked like a burning rune.

This rune is called the Flame Blood Spirit Rune, and creatures are not static in the process of growth, in fact, creatures are evolving all the time. In the process of applying medicine to the dealer, the effect of the first time is always the best, and the result is not as good as the first time. Because there is always a pest that resists the toxicity of the drug, it does not die, and the harsh environment promotes its evolution. Because of the notoriety, the Blood Spirit Grass was burned on the continent thousands of years ago, which made the Blood Spirit Grass disappear overnight, but among the tens of thousands of Blood Spirit Grass that were burned, there was always one that was not burned, and the fire of the human race prompted its evolution, this new plant is called the Flame Blood Spirit Grass.

Ordinary flames can't burn it at all, only the soul fire of a rune mage can burn it. Or after reaching the realm of the Yuan Spirit, you can also cut this grass with your excellent strength, and there is no other way.

Cangjian succeeded in refining the rune for the first time, although there was some luck element, but if it relied on the memory inherited from the Rahu Yuanshen, and this rune because Cangjian was only shallow now, even if the refining was successful, the flame blood spirit grass that grew from this rune would not be too powerful. If it was a one-star spirit cultivator's full blow, it would be able to cut it off, in other words, the flame blood spirit grass in the sword rune could only exert one or two percent of its strength.

But even so, Cang Jian was still quite happy, he succeeded in refining the rune for the first time, and this alone was enough to be proud of.

Cang Jian happily put the rune into the ring, he began to refine the next rune, the blood lingzhi medicinal liquid, the heavenly spirit herbal liquid, each with a drop, Cangjian quickly sealed, pulling the liquid fused with the true yuan quickly condensed into the rune, "It's really easy." Cang Jian couldn't help but say proudly.

However, at the moment when the rune was about to take shape, there was a very small fluctuation in the soul power of Cangjian, resulting in a continuous lack of output, and then only a snort, the liquid that the two places fused in mid-air turned into flying ashes......

Cang Jian secretly shouted yes, those two drops of liquid medicine are also dozens of taels of gold! Especially the liquid of the blood lingzhi, it is gone after a few failures, and Cang Jian can't afford to be defeated. Now I really realized how rich those apprentices who have just started to learn rune spells are, you must know that the stability of their soul power is definitely not as good as their own, thousands of taels of silver a day are lost, and not necessarily a rune is successfully made.

However, with the experience of this first failure, Cang Jian's control of soul power became more and more careful, with the rapid formation of his fingers, one rune after another continued to jump out of his fingertips, of course, there are often times of failure, but the number of failures of Cang Jian is constantly decreasing, Cang Jian is drawing quickly, but soon his true yuan can no longer support it, the fifth layer of the spirit gathering is too weak, even if he cultivates the Chaos True Yuan Decision, the top-level soul law such as the Sanqing Soul Decision still cannot last.

The true yuan can't support the production of runes, and the rune drawing of the cangjian is no longer as easy as before, and there are more and more mistakes, and each mistake is not only a waste of silver taels, but also an additional waste of the true yuan.

The true yuan is getting less and less, but Cangjian's rune drawing process is only halfway through, but he has a feeling that he is unsustainable, powerless, there is not much true yuan left in his body, and if he is not careful, Cangjian feels a dizziness in his brain, and then the runes floating in front of him also began to tremble violently, almost collapsing automatically. Cang Jian secretly screamed badly, and hurriedly stabilized the true yuan, cold sweat broke out on the back of his palms, this mess of things is dozens of taels of gold, but it can't be wasted, and it has to be used to the fullest.
