This fusion was not the same as the typical fusion of soul bones.
After five soul bones gathered around [Asura], its fourth soul ring flashed.
The Blood Refining Furnace immediately absorbed and fused the five soul bones.
These invaluable soul bones were "melting" right before Li Yu eyes.
The melted "essence" was poured onto [Asura], and soon after, a layer of armor appeared on its limbs, with many tendrils growing from its back.
At this moment, [Asura]'s aura became even more terrifying.
However, Li Yu did not sense the appearance of any new "skills."
After this fusion, although [Asura] became stronger, the skills from the soul bones had completely "vanished."
"It doesn't matter, I'm not lacking anyway," Li Yu shook his head, not too concerned.
"Next, I'll go to the Sun-Moon Continent," Li Yu decided after a brief moment of contemplation.
Since he ultimately chose the path of "using his body as a seed," he naturally gave up on the backup plan of making the Evil Eye Tyrant King his second Martial Spirit.
Now, whether or not he went to the Sun-Moon Continent seemed unimportant.
However, he had already promised Lou Gao that he would send him to the Sun-Moon Continent to learn about soul-guided weapons.
He couldn't break his word.
At the same time, though the Evil Eye Tyrant King was a spiritual-type soul beast, it had over 700,000 years of cultivation. If it became a soul ring, it would definitely bring great benefits.
Additionally, [Asura] was still lacking its torso and skull. The Evil Eye Tyrant King would be a perfect match to form the skull.
Though after being defeated by Huo Yuhao, the Evil Eye Tyrant King had become a very special external eye bone, that didn't matter. He could just throw it into the Blood Refining Furnace and refine it along with the others.
After making up his mind, Li Yu didn't linger.
With a step, he reappeared above the Northern Sea City.
He gave it a quick glance, and then the space power surged again, with countless threads unfolding before him.
A few seconds later, he took a step.
The space rippled and then returned to calm. Li Yu was already in Gengxin City.
He entered Lou Gao's room, only to find that no one was there.
"Where is he?" Li Yu wondered, spreading his spiritual power. But immediately, his expression changed drastically, and he froze.
At the same time, a terrifying aura was released from him.
His figure vanished in an instant, and then reappeared above Gengxin City.
He hadn't paid attention when he first arrived, still thinking about [Asura] and other matters, and had entered Lou Gao's office directly.
But when he found Lou Gao missing, he released his spiritual power, and as the entire Gengxin City fell under his perception, he realized that not only was Lou Gao gone, the entire Gengxin City was empty!
Not a single person was there, and the furnaces had been extinguished for an unknown amount of time.
Gengxin City, being the headquarters of the Blacksmith Association, had a smaller population compared to other cities of the same level.
But there were still hundreds of thousands of people living there.
Yet, now, everyone had suddenly disappeared without a trace. It was even stranger than if the city had been destroyed, which would have left at least some evidence behind.
But there were no traces at all.
The hundreds of thousands of people in this large city seemed to have vanished into thin air.
"How is this possible?" Li Yu muttered, disbelief filling his eyes.
He thought to himself, with his current strength, causing the entire Gengxin City to vanish in an instant would not be difficult.
But leaving no traces at all? That was almost impossible.
Traces aren't just left by battles.
Soul power, spiritual power, etc., once they fluctuate too much, they always leave marks.
This was nearly unavoidable.
"Wait, could it be the Holy Spirit Cult?" Li Yu suddenly woke up, thinking back to the strange metal he had obtained from Lou Gao.
It had traces of the Holy Spirit Cult's power, and it possessed an eerie "regeneration" ability.
Now, it had been absorbed by [Ying Yu], and although its power had become less prominent among the various metals and soul bones, it still provided a substantial boost to [Yi].
Due to the numerous events that had happened afterward and his intense focus on researching his second Martial Spirit, Li Yu had almost forgotten about this matter.
But now, it struck him like a heavy blow in his mind.
His spiritual power was immediately pushed to its limit, and his Elemental Elemental Vision unfolded. The world shifted in color before his eyes.
He scanned Gengxin City inch by inch, trying to find some clue.
Unfortunately, he found nothing.
Finally, he laid out the spatial threads before him, but still, there was no missing connection.
"What exactly happened?" Li Yu was perplexed.
From what he knew of the Holy Spirit Cult, there seemed to be only one possibility.
That was, just like the Holy Spirit Cult members and a few elders of the Clear Sky Sect had done in the past, they had directly dissolved.
Only in that way could they do it silently and without leaving a trace.
But then, what method could allow them to infiltrate the bodies of hundreds of thousands of people without being noticed?
Gengxin City wasn't just made up of ordinary people; there were also many soul masters.
For example, Lou Gao was a Spirit Saint-level being.
This wouldn't be a problem for Li Yu, but for anyone on the mainland, that was an existence powerful enough to establish a sect.
But now…
Where was he supposed to look for this Holy Spirit Cult?
Li Yu was in great distress. With his current spiritual power, he couldn't find any useful clues, let alone search like a headless chicken across such a vast land.
His gaze shifted, and with another step, he appeared in the Star Dou Forest.
The spatial threads unfolded, and the missing connection that had been hidden beneath the Star Dou appeared before his eyes.
With another step, he was inside.
The broken altar still lay like a ruin, with no changes whatsoever.
It seemed as if nothing had returned here since that time.
"Did the Holy Spirit Cult leader not come back to check after escaping?" Li Yu raised an eyebrow, confused.
After all, this place had been arranged with much effort by the Holy Spirit Cult members, and many had worked for three or four months to set it up. Now, they had abandoned it without even a glance?
Something was off.
"So, this place was just a distraction?" Li Yu frowned, then shook his head.
On this continent, who else, besides him, would be able to discover the altar hidden in the spatial threads?
He hadn't heard of anyone else mastering spatial power.
Wait...
Li Yu suddenly woke up. Who says this was meant for others to see?
This was beneath the Star Dou Forest. It was blatantly placed there for Emperor Di Tian and others to see, wasn't it?
Had someone from the Holy Spirit Cult already discovered the Star Dou Forest's seal?
Li Yu brows furrowed tightly, and he felt increasingly troubled.
At the same time, he grew more curious about who was truly standing behind the Holy Spirit Cult.
Earlier, he had been somewhat suspicious of the "Asura God" because the aura displayed by the Holy Spirit Cult leader was indeed somewhat similar.
But after deep contact, he had long abandoned that guess.
So, who was it really?
