This time, with the cultivation of the perfect soul and the activation of the soul synthesis of one of the attribute abilities of "soul refining", many of Feng Xiaowu's conjectures can be verified.

Feng Xiaowu carefully inspected this brand new soul through the "Soul Refining and Cultivating Divine Jade". The newly synthesized soul of "Soul Refining" is one level more powerful than the two "materials" before the synthesis.

It seems that the soul is also the same as the Warcraft, it is graded. Combining two souls of the same level will increase the level of the merged soul by one level.

This brand-new soul that was casually synthesized using the "Soul Refining" ability, although it looked slightly flawed, was much more perfect than the remnant soul of the Warcraft before it was not recuperated.

Next, Feng Xiaowu took out two perfectly nourished rat souls, using one of them as the main body and the other as the material for soul refining and synthesis.

The "Soul Refining and Cultivating Divine Jade" flashed, and the two rat souls were synthesized extremely smoothly. The new souls that appear after synthesis are still rat souls.

And there is only a slight crack in this newly synthesized soul.

Then, Feng Xiaowu took out two perfectly nourished rat souls and repeated the synthesis operation just now.

This time, the synthesis process is still the same as before, and the whole process is extremely smooth. There is also a very small crack on the newly synthesized soul.

It seems that the synthesis of two souls of the same kind will leave some slight damage to the souls that are synthesized by soul refining.

Feng Xiaowu synthesized the souls of these two, both of which had a trace of cracks, into the "Soul Refining and Cultivating Divine Jade" again, using one of them as the main body and the other as the material for soul refining and synthesis again.

Soon, the soul refining synthesis was over.

This success proved Feng Xiaowu's conjecture, and he was able to refine his soul many times and synthesize his soul smoothly.

The new soul of the secondary synthesis has another layer of improvement in strength. In other words, this soul has been raised by another level.

However, on this new soul of secondary synthesis, more than a dozen cracks appeared.

The damage left by the second soul refining synthesis this time was much greater than that of the first one.

There is no difference in the process of synthesizing souls by activating the soul refining skill of "Soul Refining and Cultivating Divine Jade" twice.

The reason for this result should be the "material".

It seems that the synthesis of a flawed soul will cause far more damage to the soul than the synthesis of a flawless soul.

This is also the reason why there is no way to carry out secondary synthesis before the soul is warmed, but it can be resynthesized after it is warmed.

According to Feng Xiaowu's estimate, this new soul full of cracks in the secondary synthesis, if it is reheated to perfection, it should be able to continue refining and synthesizing.

After trying the same kind of souls, Feng Xiaowu began to try to synthesize between different kinds of souls.

Feng Xiaowu took out a fourth-order snake demonic beast soul and a fourth-order lizard-type demonic beast soul from the god-recuperating area.

These two souls are very different, but there are some similarities. This is a representative step-by-step trial.

Feng Xiaowu took the soul of the fourth-order snake demonic beast as the main body, and the soul of the fourth-order lizard-like demonic beast as the auxiliary material, and put it all into the "soul refining" area of the "soul refining and nourishing god jade".

Feng Xiaowu activated the soul refining ability of the "Soul Refining and Cultivating Divine Jade" and synthesized these two souls with considerable differences. Until the soul is warmed, this very different xenomorph soul can never be synthesized.

The "Soul Refining and Cultivating Divine Jade" flashed, and this time the soul refining synthesis was actually successful!

This is something that will never happen before the warmth.

It seems that after the soul is warmed by the nourishing attribute, it will bring great changes to the soul. Tempered souls are not as repulsive to other kinds of souls as they used to be. Make the original impossible possible!

The new soul strength synthesized by the two fourth-order Warcraft souls has reached the strength of the fifth-order Warcraft souls.

The appearance of this new soul made Feng Xiaowu a little surprised.

This new soul, which is mainly based on snake souls and synthesized with lizard-like souls, has undergone a lot of changes in appearance.

This new soul looks like a snake, but it has something that is impossible to find in a snake. Under the snake-like body, there are four tiny claws.

This strange appearance surprised Feng Xiaowu to see.

In addition to its strange appearance, there are many rifts in this newly synthesized soul.

On the new soul of this xenomorph soul that was first synthesized, there were even more rifts than the damage left by the second synthesis of the same kind of soul just now.

It seems that the greater the difference in souls, the stronger the repulsion when synthesized. The greater the repulsion, the more damage to the soul will be.

Feng Xiaowu looked at the new soul of this snake and lizard soul, there were so many rifts.

In such a state, it should not be possible to carry out secondary synthesis. Reluctantly carry out secondary synthesis, it is estimated that it will also fail.

Such a soul must be recuperated before it can be refined and synthesized again.

Feng Xiaowu put this new soul and the new soul that was synthesized twice just now into the "Nourishing God" area for recuperation.

Subsequently, Feng Xiaowu took out a bird demonic beast soul and a rat demonic beast soul from the god-recuperating area.

The two demonic beast souls this time are even more different than the two just now.

Feng Xiaowu put these two demonic beast souls into the "soul refining" area for synthesis.

This time, the synthesis still worked!

The new soul is a little different from what Feng Xiaowu expected.

This time, the new soul synthesized looks even stranger. The body is still the shape of a mouse, but it has a pair of huge wings. And the whole body is covered with bird feathers.

It looks very strange, bats don't look like bats, and birds don't look like birds.

This time, the difference between the two souls is too big, and in the process of soul refining and synthesis, the rejection is also stronger. This is even more damaging to soul synthesis.

The newly synthesized soul is full of cracks, and it looks as if it may collapse at any time.

This soul can't stand the toss anymore!

Feng Xiaowu threw this soul full of cracks into the "Nourishing Spirit" area for recuperation.

These new and mature souls are very representative, and this is an important material for future experiments.

Subsequently, Feng Xiaowu did many experiments.

After many experiments, Feng Xiaowu concluded that the main factors affecting soul synthesis depended on the type of soul and the degree of perfection of warmth.

If the soul types are very different, the synthesis may fail. Another time, because the difference in souls was too large, it was clear that the synthesis was successful. It disintegrated and shattered after a few seconds.

All of the soul synthetics that weren't particularly different were successful.

This means that the same type of soul or soul synthesis with little difference can be used. The odds of success are very high.

If you keep it warm, wouldn't it be possible to synthesize it forever?

Such a result made Feng Xiaowu happy.
