At the first light of dawn the next day, Xu Tianhao and his group were fully equipped and ready to set off, stepping into the rolling mountain range.
The purpose of this trip was very clear: to find a fourth soul ring for Ye Guyi that was compatible with her own Spirit.
This was not only about Ye Guyi's own breakthrough in strength, but also a key step in improving the team's combat power.
With Ye Guyi's current foundation and heritage, the absorption limit for her fourth soul ring had already reached the ten-thousand-year level.
The thousand-year spirit rings corresponding to an ordinary Four-Ring Soul Ancestor could no longer satisfy her needs.
Only a ten-thousand-year spirit ring with sufficient age and pure attributes could perfectly match her Spirit's characteristics, allowing her power to achieve a qualitative leap.
This was not an exaggeration, mainly because Ye Guyi's improvement this time was indeed quite massive.
Having purified so many Evil Soul Masters this time, combined with her previous foundation, she now possessed the capacity to absorb a ten-thousand-year spirit ring as her fourth soul ring.
Deep within the vast Huiyin Mountain Range, there happened to live a rare Spirit Beast called the Holy Brilliance Light Butterfly.
This Spirit Beast could be said to be the best choice for a spirit ring, tailor-made for Ye Guyi.
The Holy Brilliance Light Butterfly was an extremely rare dual-attribute Spirit Beast of Holy and Light on the Sun Moon Continent.
In the habitat of the Holy Brilliance Light Butterfly, darkness and evil would be completely purified by its inherent holy and light power.
The reason the Huiyin Mountain Range got its name was not only because the mountain range itself was hidden within a mist-shrouded secret realm.
A large part of the reason was that this mountain range was the only habitat of the Holy Brilliance Light Butterfly.
The depths of the mountain range were permeated year-round by the light aura emitted by the Holy Brilliance Light Butterfly, merging with the mountain range's hidden state, which gave it the name 'Huiyin'.
However, for such a top-tier holy attribute Spirit Beast, the breeding conditions were extremely harsh.
The Holy Brilliance Light Butterfly not only had extremely high requirements for the purity of light in its habitat, but the success rate of producing offspring was also shockingly low.
The population of the Holy Brilliance Light Butterfly race had been in a state of sharp decline for years, with the group size shrinking repeatedly, no longer possessing its former prosperity.
Even so, a lean camel is bigger than a horse; selecting a spirit ring of about ten thousand years from the Holy Brilliance Light Butterfly group in the Huiyin Mountain Range for Ye Guyi to absorb was still more than enough.
During this trip, Poison Immortal remained hidden in the shadows and did not show himself to travel with them.
Xu Tianhao and his group needed to train independently rather than blindly relying on the protection of their elders.
So Poison Immortal was only responsible for guarding against unknown dangers and protecting them in secret.
As for the conspiracy regarding the Sleep Nightmare Douluo and the arrangements of those Evil Soul Masters, Xu Tianhao had already used his mobile phone to inform his eldest brother of the information at the first opportunity.
The subsequent investigation and suppression would be taken over by the powerhouses of the Inspection Team, so they didn't need to worry or be distracted.
With all their worries gone, they naturally had no burden and concentrated on finding a spirit ring for Ye Guyi.
Once the goal was clear, the group didn't need to fumble around the outskirts of the mountain range; they only needed to head towards the habitat of the Holy Brilliance Light Butterfly.
According to ancient records in the Library Tower, the Holy Brilliance Light Butterfly's dependence on light energy reached an extreme, and ordinary mountain and forest areas simply couldn't satisfy its survival needs.
The place where they had lived for generations was precisely the area around Guangming Peak in the core region of the Huiyin Mountain Range.
That peak was the area with the densest and purest light energy in the entire Huiyin Mountain Range; Guangming Peak was very high and was not within the hidden clouds.
It was shrouded in halos year-round, and the duration of sunshine far exceeded other parts of the mountain range, making it a natural home for the Holy Brilliance Light Butterfly to thrive.
But precisely because Guangming Peak was located in the inner core of the Huiyin Mountain Range, the level of danger in the surroundings increased exponentially.
When Xu Tianhao and the others moved, they had to be extremely careful, taking every step with utmost caution.
The interior of the Huiyin Mountain Range was not like the relatively safe peripheral areas occupied by hundred-year and thousand-year Spirit Beasts; it was full of powerful Spirit Beasts of over ten thousand years.
Although the upper limit of the Spirit Beasts' age in this mountain range had not broken through to over fifty thousand years, for this group of young Spirit Masters with only Spirit Ancestor and Spirit Elder cultivation...
Spirit Beasts of the ten-thousand-year level or above posed a significant threat; if they were even slightly careless, it could lead them into a desperate situation.
In order to avoid danger to the greatest extent, the seven of them wore special stealth uniforms, pushing the uniforms' inherent invisibility effect to the limit.
A faint silver light wrapped around their bodies, merging with the vegetation and shadows in the forest; their aura and figures were perfectly concealed.
Along the way, whenever they sensed the powerful aura emitted by a ten-thousand-year Spirit Beast, the group would immediately take a detour and never have any direct conflict with it.
The group carefully shuttled through the dense forests and canyons, avoiding one powerful Spirit Beast after another that occupied territory, slowly advancing towards the direction of Guangming Peak.
They slept in the open along the way, not daring to slack off in the slightest. After a full day and night of trekking, the group finally crossed the dangerous zone inside the Huiyin Mountain Range and reached the outer perimeter of Guangming Peak.
Before even getting close to the main peak, they could see from afar a towering peak rising from the mountains, piercing into the clouds.
The peak was entirely wrapped in a brilliant golden halo of light, and the sunlight falling on the ridges reflected a sacred radiance.
And in the air above that peak, countless spots of light like golden stars were dancing; they were none other than the beautifully shaped, shimmering Holy Brilliance Light Butterflies.
They flapped their light wings as thin as cicada wings, circling and flying above Guangming Peak. As their wings brushed through the air, they left behind golden trails of light, decorating the entire peak like a fairyland.
Seeing this scene from afar, Ye Guyi's eyes instantly lit up, flashing with light of surprise and expectation.
The emotions suppressed throughout the journey were finally released, and she couldn't help but whisper: "We're finally here! We finally found the habitat of the Holy Brilliance Light Butterfly!"
But this joy only lasted for a moment before the light on Ye Guyi's face quickly faded, replaced by a bitter and helpless smile.
She looked at the large number of Holy Brilliance Light Butterflies in the distance, with varying strengths of aura, and spoke in a heavy tone:
"Look, among the Holy Brilliance Light Butterfly group, that leader with the strongest aura has a cultivation of at least thirty or forty thousand years. Even the ordinary adult individuals in the group mostly have a cultivation of over five thousand years."
"With the strength of just a few of us, how easy would it be to quietly capture a Holy Brilliance Light Butterfly of about ten thousand years in their home base?"
These words were like a bucket of cold water, instantly extinguishing the joy in everyone's hearts, and the originally relaxed atmosphere immediately became heavy.
Everyone looked at the Holy Brilliance Light Butterfly group on Guangming Peak, frowning and falling into a dilemma.
Everyone knew in their hearts that if they encountered a single ten-thousand-year Holy Brilliance Light Butterfly in the wild, even if the opponent was a top-tier Spirit Beast of the Holy and Light attributes, the seven of them working together would be absolutely certain to subdue it.
Even if they encountered one of twenty thousand years, they could preserve their lives by joining forces.
But this was the home base of the Holy Brilliance Light Butterflies, the home where they had lived for generations, and there was a very strong connection between the group.
Once they made a move and alerted one of them, it would instantly attract swarms of Holy Brilliance Light Butterflies to attack.
Holy Brilliance Light Butterflies were already good at group combat, and with the light power overlapping, their power would multiply.
If they really fell into a situation of being besieged by a swarm of butterflies, the strength of the seven of them wouldn't even be enough to fill the gaps between the teeth of this group of Holy Brilliance Light Butterflies.
At that time, let alone obtaining a spirit ring, even retreating in one piece would become a luxury; instead, they would fall into a life-and-death crisis.
Just as everyone was at a loss and had no options left.
Xu Tianhao pondered for a moment, his mind rapidly calculating feasible plans.
After a moment, he looked up at everyone: "Everyone doesn't need to be troubled, just leave this matter to me."
"I will first use the moon reading space to pull a selected ten-thousand-year Holy Brilliance Light Butterfly into it alone. I'll guide and train it within the space to make it lose its guard, and finally let it actively fall into our trap."
As soon as these words came out, everyone's eyes instantly lit up, and the clouds of worry completely dissipated.
Hearing this, Xu Tianzhen immediately walked forward with a smile and heavily patted Xu Tianhao's shoulder: "It still has to be you, Hao Hao!"
"Now only your ability can do this so trace-lessly, quietly getting a suitable one for Guyi from the Holy Brilliance Light Butterfly group. If it were any of us, it would be absolutely impossible!"
The others also nodded in agreement, with relieved smiles appearing on their faces, and their originally hanging hearts were completely set at ease.
They all knew how powerful Xu Tianhao's mental force was, and the moon reading space was a unique divine skill!
By pulling the target into it silently, the outside world wouldn't be able to perceive the slightest abnormality.
This was undoubtedly the most stable and safest way at present, bar none.
