Of course, although Tang Chuan could designate the origin of the Heaven-Bestowed Spirit Rings of the Fantasy Divine Tree, this ability was not without limits.
According to the explanation given by the comparison heaven screen, the life essence of the selected fantasy divine tree could not exceed the endurance threshold of the Douluo Plane.
After obtaining the three Heaven-Bestowed Spirit Rings of the Fantasy Divine Tree, Tang Chuan summoned one of them with a thought and held it in his palm.
After a brief moment of contemplation, he began testing its limits.
First, he attempted to designate its origin as the Chaos Green Lotus, the Hollow Willow, or the Lunar Laurel Tree from the Prehistoric World, and even the World Tree from the Perfect World.
However, every attempt ended in failure.
Left with no alternative, Tang Chuan adjusted his expectations and chose to designate the origins as divine-level Plant Spirit Beasts that could theoretically exist on Douluo Star.
Only then did the process finally succeed.
In the end, Tang Chuan assigned the three Heaven-Bestowed Spirit Rings of the Fantasy Divine Tree to originate from Jianmu, the Undying Moon Laurel Tree, and the World Tree.
According to the information provided by the comparison heaven screen, these Heaven-Bestowed Spirit Rings of the Fantasy Divine Tree could be absorbed in two ways. They could either be used at a cultivation bottleneck, such as when reaching Rank 70 to become the seventh spirit ring, or they could directly replace previously absorbed spirit rings through devouring.
After the replacement, Tang Chuan would have the option to retain the original spirit abilities, upgrading them to match the age of the Heaven-Bestowed Spirit Ring of the Fantasy Divine Tree.
Since he had designated the origins as the Undying Moon Laurel Tree and Jianmu, Tang Chuan had clear expectations for the abilities he wanted.
For the Heaven-Bestowed Spirit Ring derived from the Undying Laurel, he aimed to obtain its near-immortal regenerative power.
As for the one derived from Jianmu, he hoped to gain the qualities of a sky-reaching divine tree.
After careful consideration, Tang Chuan decided to first absorb the Heaven-Bestowed Spirit Rings derived from the Undying Laurel and Jianmu, using them to replace his first and second spirit rings.
As for the Heaven-Bestowed Spirit Ring derived from the World Tree, he chose to reserve it until his cultivation reached Rank 80. At that point, he could absorb it directly without worrying about preserving previous abilities.
After all, whether it was the World Tree's power to nurture worlds or its authority over space, he intended to claim them both.
After the comparison video concluded, within the Ice and Fire Yin Yang Well, Tang Chuan summoned his Blue Silver Life Tree Martial Soul with a thought.
The enormous tree emerged, its form rising from the Yin Yang Well as six spirit rings ascended in sequence around him. Four black rings, one red ring, and another black ring radiated immense pressure as they revolved.
Taking out the Heaven-Bestowed Spirit Ring derived from Jianmu, Tang Chuan took a deep breath and prepared to absorb it.
In theory, he understood that the optimal strategy would be to wait until reaching the Limit Douluo realm, when his body could withstand million-year spirit rings, before absorbing these treasures. That approach would maximize their potential.
However, the comparison heaven screen would eventually expose the existence of the Ice and Fire Yin Yang Well, which would undoubtedly attract the attention and greed of powerful forces across the continent.
Because of this, Tang Chuan had no choice but to strengthen himself as quickly as possible.
By temporarily setting aside the World Tree spirit ring while absorbing those from Jianmu and the Undying Laurel, he had found a balance between immediate strength and long-term potential.
"Let's see if the abilities from this Jianmu spirit ring match my expectations," Tang Chuan murmured with anticipation as he began the absorption process.
In the next instant, a brilliant golden light burst from his body, illuminating the entire Ice and Fire Yin Yang Well.
Soon, a golden spirit ring slowly rose from beneath his feet and moved toward his first spirit ring, devouring it completely.
Immediately afterward, a surge of information flooded into his mind.
It detailed the spirit abilities granted by the Heaven-Bestowed Spirit Ring derived from Jianmu.
Because Tang Chuan's current physical strength was already capable of handling spirit rings exceeding one hundred thousand years, the Jianmu spirit ring directly manifested at that level and granted two spirit abilities.
The first ability, which Tang Chuan named Jianmu Connecting to Heaven, could instantly enlarge the Blue Silver Life Tree Martial Soul by a hundred times while greatly enhancing its quality, toughness, and defensive strength.
The second ability, which he named Void Siphoning, allowed the tree's roots and branches to pierce through space and anchor themselves within the void, drawing in the violent energies of heaven and earth and converting them into any form of energy he required, whether spiritual qi, spirit power, or life force.
"Excellent. Both of these abilities are exactly what I need."
As he reviewed the abilities, Tang Chuan's crystal-blue hair shimmered softly, and his already strikingly handsome face lit up with clear satisfaction. Without hesitation, he confirmed both abilities.
Afterward, he took out the Heaven-Bestowed Spirit Ring derived from the Undying Moon Laurel and began absorbing it as well.
Another golden spirit ring rose from beneath his feet and devoured his second spirit ring.
Once again, a stream of information entered his mind.
Like the Jianmu ring, the Undying Laurel spirit ring also manifested at over one hundred thousand years and granted two abilities.
The first ability, which Tang Chuan named Undying Body, greatly accelerated the growth of the Blue Silver Life Tree Martial Soul and granted it near-immortal vitality. Even if it were cut apart or shattered, it could regenerate instantly and fully recover.
The second ability, which he named Moonlight Praise, functioned as a supportive skill. It converted spirit power into Moonlight Power, which possessed extremely powerful healing properties.
However, Tang Chuan had already fused with the 100,000-year Blue Silver Emperor right leg bone, gaining its second ability, "Wildfire cannot consume it, the spring breeze brings it back to life." In addition, several of his existing abilities already provided life force regeneration.
As a result, he felt that Moonlight Praise was somewhat redundant.
In contrast, his original second spirit ability, Parasitic Seed, offered far greater synergy when combined with his other abilities, often producing effects greater than the sum of their parts.
For example, if he activated Jianmu Connecting to Heaven and enlarged his Blue Silver Life Tree by a hundred times, the Parasitic Seeds it produced would likely grow to the size of basketballs.
Such massive seeds, once embedded in an enemy, could drain them dry almost instantly.
Moreover, their increased size would allow them to store far more Thunder Power, making them even more devastating.
After careful consideration, Tang Chuan chose to retain Undying Body and replace Moonlight Praise with his original Parasitic Seed as the two abilities of his second spirit ring.
With the successful absorption of the Heaven-Bestowed Spirit Rings derived from Jianmu and the Undying Moon Laurel, the Blue Silver Life Tree Martial Soul underwent another profound transformation.
It became even more massive and imposing, its trunk expanding to over five meters in diameter and its height surpassing one hundred meters. Its canopy grew dense and vibrant, while crystal-like silver-white flowers blossomed among the leaves, giving it an almost divine presence.
