Under Zhou Yang's manipulation, the demon liquid slowly fused with the golden apple tree, and finally all of it infiltrated into every inch of the fruit tree's branches and leaves.

What's more, Zhou Yang opened the Eye of Insight and integrated these demon liquids into every cell of the fruit tree.

Soon, the golden apple tree became completely different, originally named after its fruit, but now it is golden yellow throughout, as if it were made of gold, like a beautiful work of art.

What surprised Zhou Yang even more was that he could feel that the golden apple tree in front of him seemed to produce a faint breath.

The breath was very slight, but it began to slowly absorb the power of heaven and earth, and then a faint aura escaped from the golden apple tree.

Moreover, this aura is still very pure, although it is useless to Zhou Yang, but if an ordinary person absorbs this aura, he can even wash his muscles and cut off the marrow, and embark on the road of evolution from now on.

Zhou Yang was amazed by this, this kind of situation of absorbing the power of heaven and earth, and then swallowing out the spiritual energy, was not something that ordinary spirit plants could do.

As far as Zhou Yang knew, the only thing that could do this was the Heaven and Earth Spirit Root.

Before being refined into a magic weapon by Zhou Yang with a blood refining array, this golden apple tree was just an ordinary spiritual plant, although it had the power of life breathing, it only slowly swallowed the power of heaven and earth, and never spit out spiritual energy.

And after being refined into a magic weapon, he directly lost his life.

But what Zhou Yang didn't expect was that after this golden apple tree was integrated into the Earth Demon Stone, there would be such a change.

Zhou Yang could feel that this golden apple tree was definitely not a heaven and earth spiritual root, but being able to swallow spiritual energy meant that it was already different from ordinary spiritual plants, and its value had also increased exponentially.

Heaven and earth have a variety of energy bodies, such as immortal qi, demon qi, fighting qi, chakra, etc., which are relatively easy to absorb, but there are also powers similar to the power of death and the power of desperation, which cannot be absorbed at all.

And aura is also the most ordinary and inclusive energy in heaven and earth.

Although Reiki also has attributes, there is no doubt that Reiki is definitely the easiest energy to absorb.

However, not all places have abundant aura, and even some places are pure aura Jedi.

And at this time, the role of the spiritual root of heaven and earth is revealed.

It's like an ordinary plant has the ability to absorb carbon dioxide and release oxygen.

Generally, the Heaven and Earth Spirit Root can also absorb some bad energy, thus releasing a purer aura.

Reiki is a relatively mild force, even ordinary people who have not practiced can absorb this energy, unlike some high-level energy, if ordinary people absorb it, they may even explode directly and die.

However, the attributes of the spiritual roots of heaven and earth are different, and the attributes of the spiritual energy that are exhaled are also different, just like a person who only has the power of the water attribute, but accidentally obtains the heaven and earth spiritual root of the fire attribute.

The aura of the fire attribute heaven and earth spirit root is naturally also fire attribute, and it is difficult for this water attribute person to absorb this fire attribute aura.

However, no matter what, the spiritual root of heaven and earth is still very precious, especially for the greater the forces, the greater its importance.

And now this originally ordinary spiritual plant actually has the ability to swallow aura, although the amount of aura swallowed by the golden apple tree is too small, not even one percent of the sun tree.

But this still greatly increased the value of this golden apple tree, not to mention, this tree was only refined by Zhou Yang casually, and even if Zhou Yang was given time, he could refine this spirit plant in large quantities.

When Zhou Yang planted this kind of spiritual plant on the major islands of the Heavenly Sect, the amount of spiritual energy he could absorb would definitely not be weaker than that of a Sun Tree.

"After fusing the Goblin Stone, there will be such a change?" Zhou Yang said with great surprise in his heart, "Is it only this kind of spirit plant that has been fused with the Earth Demon Stone to have this kind of change, or will all the items that have been fused with the Earth Demon Stone have this kind of change?" ”

Zhou Yang thought of this question, so he immediately took out a long sword, this long sword was definitely a hundred refining products before the end of the world, but now it is just an ordinary iron sword.

He threw the long sword into the Blood Refining Array, and then separated a part of the Earth Demon Liquid and merged it into the long sword.

Under Zhou Yang's manipulation, the two quickly merged together.

After fusing the demon liquid, this originally ordinary long sword immediately became different, becoming more hard and sharp.

Zhou Yang used his long sword to slash at the iron block at his feet, and instantly split the iron block in half.

This piece of iron was the waste left over from Zhou Yang's experiment, but the hardness of this piece of iron was not something that an ordinary mortal realm cultivator could break.

It can be seen that the power of this iron sword has increased a lot, if it was said that in the past, only mortals could see it, then now even mortals will yearn for such a weapon.

However, to Zhou Yang's regret, he did not feel the same change in this long sword as the golden apple tree.

"It seems that not all weapons will produce this kind of change" Zhou Yang came to a conclusion in his heart, and also had a little regret, "If this kind of earth demon stone can really give life to weapons, then you can manufacture this kind of weapon that can continue to grow in large quantities."

Zhou Yang regretted in his heart, but he was not surprised, how high the value of a weapon that can grow independently, needless to say, Zhou Yang knows very well.

If you have a weapon like this, as long as the master doesn't hang up and keeps growing, this weapon will always be able to follow him to practice.

If the Earth Demon Stones really have such a powerful function, then for the sake of this powerful benefit, they will definitely become the target of public criticism, and even have the disaster of extermination.

Zhou Yang didn't continue to dwell on it, he probably guessed why this long sword didn't become a growth weapon.

After all, this weapon is not like the previous golden apple tree, which was originally an inanimate object, unlike the golden apple tree, which was originally a living spiritual plant.

It's just that after Zhou Yang used the blood refining array to refine it into a magic weapon, his own life was also erased by Zhou Yang.

And the earth demon stone is the core of the earth demon, which can be said to be another strange spiritual object, Zhou Yang integrated the earth demon stone into the golden apple tree, so that the earth demon stone replaced the life spirituality of the golden apple tree that was erased, so as to have life again.

Even because of the value of the Earth Demon Stone, this golden apple tree has the ability of a part of the Heaven and Earth Spirit Root in one fell swoop.

However, Zhou Yang estimated that if he hadn't mastered the Blood Refining Array and was able to perfectly fuse the Earth Demon Stone with the Golden Apple Tree, it would have been extremely difficult to bring the Golden Apple Tree back to life.

With this guess, Zhou Yang did not immediately start refining the Sun Tree, but continued to conduct experiments, constantly refining spirit plants one by one.
