I will use the ninja world to aid my cultivation of immortality.

Besides attribute-type spiritual veins, there is another type of spiritual vein that is particularly special: mutated spiritual veins.

So-called mutated spiritual veins are often caused by certain factors that lead to abnormal changes in the spiritual veins.

This mutation can be benign or malignant.

Benign mutations may allow the nurtured spiritual energy to not only enhance cultivation but also produce positive effects such as strengthening the body.

If it's malignant, the spiritual energy it produces may contain highly toxic substances, making it difficult for people to absorb.

Chapter 200: The Bronze Tower Reawakens! Spiritual Root Metamorphosis!

"Let's see if we can absorb it!"

After a moment's thought, Naraku raised his hand and drew a fist-sized ball of energy from the dragon vein.

Regardless of whether a dragon vein is truly a spiritual vein, it only has value if it can enhance one's cultivation.

The true fire cauldron condenses, and the energy of the dragon vein is thrown into it.

True gold is refined by fire.

The dragon vein energy, being refined by the True Fire Cauldron, subtly distorted, seemingly resisting the refining process as if it possessed a consciousness.

This situation caused Naraku to frown slightly.

When he probed with his divine sense just now, he found that the aura of the dragon vein was very strange, violent yet peaceful.

At this point, the violent side of the process is fully revealed, making the refining process exceptionally difficult.

"Could it be that the dragon vein truly possesses its own consciousness, allowing only its use but not its refinement?"

The thought flashed through Naraku's mind.

In the original storyline, An Lushan extensively used the dragon vein to control puppets.

Given the current difficulty in refining it, he couldn't help but think about it more.

It seems to be in response to Naraku's thoughts.

As the refining process continued, the dragon vein energy within the True Fire Cauldron resonated with the dragon veins in the outside world.

"not good!"

Naraku noticed the abnormality of the dragon vein immediately.

When Naraku sensed the ripples spreading within the dragon vein, resembling an awakened volcano about to erupt lava, his expression changed, and he immediately prepared to use "Shrinking the Earth to an Inch" to leave.

Dragon veins are extremely mysterious.

In the original storyline, it even allowed people to travel through time and return to the past.

Regardless of what will happen to the dragon vein next, Naraku will certainly not take the risk lightly.

hum!

Suddenly, just as Naraku was about to activate "Shrinking the Earth to an Inch", another unexpected event occurred.

It is a bronze tower.

The bronze tower, which had remained silent since the awakening of its innate wisdom, now seemed to resonate with the dragon vein.

With a slight tremor, the bronze tower, through Naraku, instantly generated an astonishing suction force, enveloping the entire dragon vein.

boom! ! !

It's like all rivers flowing into the sea.

Just as the dragon vein was about to go berserk, it suddenly became like a child seeing its parents, obediently flowing into Naraku's body under the suction of the bronze tower until not a single drop remained inside.

"What--"

Naraku's eyes widened.

The strange phenomenon of the bronze tower appeared too suddenly, and even with his reaction speed, he couldn't keep up.

By the time he realized what was happening, the dragon vein had already passed through him and entered the bronze tower.

And that wasn't the end of it. The bronze tower that absorbed the dragon vein immediately unleashed indescribable power, sweeping through Naraku's limbs and bones.

His body shuddered, and Naraku, as if drunk, swayed and collapsed to the ground.

Fortunately, the immense power emanating from the bronze tower dissipated after only a few breaths.

However, Naraku, who had fallen to the ground, did not get up immediately. Instead, he closed his eyes as if he sensed something.

After a long while, Naraku slowly opened his eyes.

"I never expected to have such good fortune. The dragon vein actually caused the bronze tower to revive," Naraku thought in amazement.

The feeling he had just experienced was actually a message being conveyed to him by the bronze tower.

For example, the unusual phenomena of the bronze tower were indeed caused by the dragon vein.

The situation is similar to a person who has been starving for a long time suddenly finding a table of food, and naturally cannot help but go forward and have a hearty meal.

Similarly, the bronze tower, which had been dormant, was revived because it was replenished with food.

Although this recovery was only a drop in the ocean, it still awakened some of the Bronze Tower's power.

What a wonderful experience that just happened.

The immense power of the bronze tower that swept through Naraku's body was something Naraku had actually experienced once before.

It was when he awakened his innate wisdom that the bronze tower shaped his spiritual root.

Now that the Bronze Tower has been revived, it is to reshape his spiritual root, not only upgrading his original low-grade spiritual root to a mid-grade spiritual root, but also transforming it into a unique spiritual root.

That's right, it's a different kind of spiritual root.

Just like spiritual veins, spiritual roots also exist in special types.

In addition to normal spiritual energy absorption, those with unique spiritual roots also possess extraordinary powers, much like those born with exceptional talents.

"The unique spiritual root that the Bronze Tower sculpted for him seems to possess extraordinary power derived from the dragon vein!"

Like an instinct, Naraku could clearly sense the special power possessed by the alien spiritual root.

Having a different spiritual root does not necessarily mean it is more powerful than having a normal spiritual root.

Some unique spiritual roots may only possess special powers that are good for amusing children.

However, Naraku's unique spiritual root clearly does not belong to this category, simply because the special power contained in his unique spiritual root is 'space-time'.

Time is king, space is supreme!

The power of spacetime, no matter which world it is placed in, is definitely one of the most powerful forces.

Coincidentally, the Dragon Vein demonstrated the power of time travel in the original storyline.

The Bronze Tower was revived by the Dragon Vein, and the alien spiritual root it created for Naraku was clearly infused with the spacetime power contained in the Dragon Vein.

"On the path of cultivation, nothing is more indispensable than opportunity, and the Bronze Tower is my greatest opportunity!" Naraku exhaled a breath of turbid air, and a smile appeared on his face from the bottom of his heart.

His current unique spiritual root, not to mention the spacetime power it contains, is enough to bring huge benefits just by advancing from the low grade to the middle grade.

Although there is only a difference of one grade between low-grade and mid-grade, the efficiency of their spiritual energy absorption and exhalation is at least five times greater.

In other words.

Naraku's subsequent training, even with normal breathing of spiritual energy, will increase his training speed by at least five times.

With such a significant promotion, how could he not be happy?

Moreover, the transformation of spiritual roots is only one aspect.

The power awakened by the bronze tower not only brought about the transformation of spiritual roots, but also restored a certain amount of its own power.

On the vast sea, a figure flashed repeatedly, quickly appearing above a deserted island with a diameter of about ten kilometers.

A golden vertical pupil appeared between his brows. Naraku, who had stopped using the "Shrinking Earth to an Inch" technique, activated the "Great Property" technique with his Heavenly Eye and stood in the void.

He looked down at the deserted island below, and immediately raised his right hand, conjuring a phantom bronze tower in his palm.

"Although it's just a projection, with the power the Bronze Tower has awakened so far, the Projection Tower is comparable to a Grade Earth Magic Treasure!"

Naraku's gaze fell upon the illusory bronze tower that had materialized in his palm, his eyes burning with intensity.

He came to the sea to test the power awakened by the Bronze Tower.

The illusory tower he is currently conjuring in his palm is a projection of the bronze tower.

Naraku looked down at the deserted island again, and without hesitation, immediately activated the projection tower by circulating his true energy.

hum!

The projection tower, infused with true energy, trembled.

The projection tower seemed to be a bottomless pit.

It took Naraku a full ninety percent of his true energy to activate it.

The exaggerated consumption of true energy made Naraku feel a chill, and he immediately flipped his palm and threw out the projection tower.

Boom! ! !

The projection tower plummeted to the deserted island below like a meteor, rapidly growing larger along the way until it became a colossal tower a hundred feet tall.
