External Soul Bone: Thunder God's Spine—Extreme Life Flow Was the Best Path of Development

In the end, Tang Chuan successfully fused with the External Soul Bone brought by the Thunder Roaring Hell Vine Spirit Ring. He slowly opened his eyes, his handsome face bright with surprise and delight.

"I never expected the Thunder Roaring Hell Vine to actually grant an External Soul Bone. It truly lives up to its legendary name!"

Tang Chuan murmured to himself in excitement and joy.

After successfully fusing with the External Soul Bone bestowed by the Thunder Roaring Hell Vine Spirit Ring,

Tang Chuan first activated the Third Spirit Ability from the Thunder Roaring Hell Vine Spirit Ring, then activated the Spirit Bone ability of the External Soul Bone.

After testing it, Tang Chuan named the Third Spirit Ability from the Thunder Roaring Hell Vine Spirit Ring: Thunder Prison!

Its effect was to summon vast swathes of pitch-black storm clouds within a designated area after a certain amount of time. Once they had gathered for a while, they would unleash lightning from the sky to attack enemies.

The heavenly lightning it summoned was extraordinarily powerful.

However, Tang Chuan's Blue Silver Crystal Vine Martial Soul could absorb the power of lightning and convert it into its own Soul Power and life force, increasing the Blue Silver Crystal Vine's growth and recovery speed.

During the effects of Thunder Prison, the Blue Silver Crystal Vine's limits for enduring and absorbing lightning, as well as its limits for converting it into Soul Power and life force, would be greatly enhanced.

Moreover, each time it took damage, its toughness and growth and recovery speed would receive another boost.

Of course, this enhancement had a limit, but Tang Chuan had yet to determine what that limit was.

After testing the Spirit Bone ability of the External Soul Bone, Tang Chuan discovered that it could condense a lightning spear that locked onto a target and attacked enemies.

Besides that, it also possessed a passive effect.

It could absorb any lightning power it received and store it away. That energy could be converted into Soul Power and life force, or used to increase the lightning spear's power when activating the Spirit Bone ability.

Since both the Third Spirit Ability, Thunder Prison, and the External Soul Bone came from the Thunder Roaring Hell Vine, the Third Spirit Ring and the External Soul Bone resonated with and influenced each other, enhancing the effects of both the Spirit Ring ability and the Spirit Bone ability.

Tang Chuan named the External Soul Bone from the Thunder Roaring Hell Vine the Thunder God's Spine, while its Spirit Bone ability was named the Thunder God's Spear!

With the Third Spirit Ability, Thunder Prison, and the passive effect of the External Soul Bone, Thunder God's Spine, Tang Chuan would be completely unaffected by the heavenly lightning attacks of Thunder Prison.

"Hiss—!!"

When Ning Fengzhi saw the results Tang Chuan had obtained in the Comparison Video after testing the Third Spirit Ability from the Thunder Roaring Hell Vine and the Spirit Bone ability of the External Soul Bone, Thunder God's Spine,

he immediately sucked in a sharp breath, utterly shaken, and could not help saying,

"As expected of the legendary Thunder Roaring Hell Vine. Its mere three-thousand-year Spirit Ability can actually alter the weather and call down heavenly lightning to attack. It even has such powerful passive effects!"

"Fortunately, changing the weather and summoning lightning both take time, so one can avoid it completely."

"Otherwise, the effects and power of this Spirit Ability would probably be no weaker than those of a top-tier ten-thousand-year Spirit Ability!"

"Sect Master, I know of this Thunder Roaring Hell Vine. It is a legendary top-tier Plant Soul Beast that possesses the Thunder God's Bloodline."

"But Tang Chuan's Martial Soul is Blue Silver Grass!"

"Even if it evolved once, it should only count as a mid-tier or high-tier Martial Soul, right?"

"A mere three-thousand-year Spirit Ring produced a Spirit Ability with such astonishing effects. Isn't that a little absurd?"

Bone Douluo Gu Rong still found it hard to believe and could not help asking.

In response, Ning Fengzhi shook his head, chuckled softly, and said,

"Uncle Gu, you are mistaken."

"Have you forgotten? Tang Chuan's Blue Silver Grass is no ordinary Blue Silver Grass. His mother, Ah Yin, was a hundred-thousand-year Blue Silver Emperor!"

"Although I do not know why Tang Chuan's Martial Soul still awakened in the form of ordinary Blue Silver Grass, its essence is certainly far from ordinary!"

"Besides, do you remember the Martial Soul Origin Completion and Evolution Theory Tang Chuan proposed before?"

At that point, Ning Fengzhi recounted the contents of Tang Chuan's Martial Soul Origin Completion and Evolution Theory with great emotion.

"Since his first Spirit Ring, Tang Chuan has absorbed Spirit Rings from top-tier Plant Soul Beasts."

"Whether it was the Myriad-Year Evergreen Vine, the Dreamy Starlight Flower, or the Thunder Roaring Hell Vine, it was always the same."

"With how weak Blue Silver Grass is, after absorbing the Spirit Rings of those three top-tier Plant Soul Beasts, all of which possessed the Life Attribute and had a high degree of compatibility, its Martial Soul origin must have been greatly replenished."

"Then there was the evolution brought about by fusing with that hundred-thousand-year Blue Silver Emperor Right Leg Bone."

"By now, Tang Chuan's Blue Silver Crystal Vine Martial Soul is at the very least a high-tier Plant Martial Soul, perhaps even a top-tier Plant Martial Soul."

"With such quality, it is not strange for him to gain a Spirit Ability like this from the Spirit Ring of the God Rank Plant Soul Beast, the Thunder Roaring Hell Vine!"

Having said that, Ning Fengzhi gave his conclusion as well.

"Judging from Tang Chuan's Spirit Ring choices and the effects of the Spirit Abilities he gained, his earlier idea was indeed correct."

"Compared to the Black World, where Yu Xiaogang designed Tang San's Blue Silver Grass Martial Soul cultivation path, Tang Chuan's Extreme Life Flow cultivation path is the truly correct one!"

The Comparison Video continued playing.

[After absorbing the Thunder Roaring Hell Vine Spirit Ring, Tang Chuan used the Soul Power Testing Crystal Ball for testing Soul Elder cultivation once again to measure his cultivation.]

[Compared with after absorbing his Second Spirit Ring, when he had directly broken through from the Twentieth Level to the Thirtieth Level,]

[after absorbing the Thunder Roaring Hell Vine Spirit Ring, Tang Chuan's cultivation had only risen from the Thirtieth Level to a thirty-eighth-level Soul Elder. He still needed two more levels to reach the fortieth-level Quasi-Soul Ancestor.]

[After breaking through to Soul Elder, Tang Chuan returned from the Star Dou Great Forest to the Blue Silver Forest and continued cultivating diligently with the Blue Silver Meditation Method.]

[Outside of cultivation, Tang Chuan continued buying and consuming Whale Rubber. And because Fragmentation Grenades had played a considerable role during this Spirit Ring hunt, he still had not given up making them.]

[But besides that, Tang Chuan was also researching the development of his Spirit Abilities.]

[Using the Thunder Attribute gained from absorbing the Thunder Roaring Hell Vine Spirit Ring as the core, Tang Chuan quickly developed combinations of different Spirit Abilities.]

[For example, when attacking with the Blue Silver Crystal Vine, he could convert Soul Power into potent lightning energy, electrifying the Blue Silver Crystal Vine so that while it bound and controlled its target, it also inflicted electric shock and paralysis.]

[Next, Tang Chuan successfully stored lightning power within the Parasitic Seeds and Pollen Spores created by the Second Spirit Ability: Parasitic Seed.]

[Once the Parasitic Seeds and Pollen Spores landed on an enemy and began taking root inside their body, releasing the lightning power afterward produced an even more excruciating effect.]

[Especially if the Parasitic Seeds and Pollen Spores took root in an enemy's head. Releasing lightning power then, before they could react, was enough to knock someone unconscious on the spot.]

[After all, the Thunder Attribute of Tang Chuan's Blue Silver Crystal Vine came from the Thunder Roaring Hell Vine. Even though it had only been gained by absorbing the Thunder Roaring Hell Vine Spirit Ring, it could still be considered a top-tier Thunder Attribute!]

Upon seeing this, countless Soul Masters in both the Black World and the White World could not help widening their eyes in shock, cold sweat pouring down their backs.

Tang Chuan had actually thought of and developed so many combinations of Spirit Abilities, and their effects were so powerful!

He was a true genius!
