The advantage of this pill lay in using blood to replace spirit rings and Free Soul Power to make up for Spirit Ring Age, allowing high-age spirit rings to be mass-produced.
Moreover, while refining the pill, a soul master could stop at any time upon reaching their limit.
They only needed to expel the remaining Pill Residue afterward, achieving true limit absorption.
Its drawback was that forming the pill required the Bu Yuan Cauldron to absorb Free Soul Power. Unless one was in a place with an exceptionally abundant supply of Soul Power, they had to keep moving and changing locations.
If he did not want to get scolded, he also had to avoid cities...
To popularize it, this process had to be improved.
The pill had to be formed without relying on the Bu Yuan Cauldron. Even a sufficiently high-age semi-finished product would do.
After all, Lin Hai could not be a wandering rogue for the rest of his life.
At present, the upper limit of Spirit Ring Pills was 99,999 years. They could not break through to one hundred thousand years.
Lin Hai deduced there were two reasons:
First, there was a fundamental gulf between Ten Thousand Year and Hundred-Thousand-Year Soul Beasts: taking human form, speaking, and inevitably producing Spirit Bones.
Therefore, Hundred-Thousand-Year Spirit Ring Pills could not be refined using the blood of Ten Thousand Year Soul Beasts.
Second, the Bu Yuan Cauldron was currently not powerful enough.
The former required another solution, while the latter only required continued refinement and waiting for the Bu Yuan Cauldron to upgrade.
Then there were Martial Spirit Pills:
Lin Hai had likewise analyzed soul master blood and discovered that it could only replicate Martial Souls, not soul skills. Perhaps soul skills were external acquisitions...
After taking a Martial Spirit Pill, a soul master could gain an additional Martial Soul and become an "Artificial Twin Martial Spirits" user.
There was also no restriction requiring the two Martial Souls to be of very similar quality.
However, the new Martial Soul could not be inherited through bloodlines, could not have spirit rings attached, and could not perform Martial Soul Fusion Skills. Only beast Martial Souls or humanoid Martial Souls could use Martial Soul Possession.
Furthermore, the drawbacks of Twin Martial Souls remained. The two Martial Souls could not be used simultaneously.
He had used Chrysanthemum Douluo's blood to create a death-row prisoner with Twin Martial Souls, then had Ghost Douluo test him. In the end, Ghost Douluo sensed nothing and killed the "fake chrysanthemum."
This pill might seem useless, but it was actually quite effective for certain types of Martial Souls.
Flight Type: one could fly simply by using Martial Soul Possession.
Take the Sharp-tailed Swallow of the Speed Clan. Even without soul skills, it was still ridiculously fast. It was definitely one of the best choices.
Before Ma Hongjun obtained his Third Spirit Ring, he could not fly because the essence of his Martial Soul at the time really was a chicken.
Element Type: one could perform basic manipulation of the relevant element without soul skills.
For example, the Martial Souls of the Four Elements Academy. Well... they could make do with things like taking a bath or starting a fire...
Imagine them paired with Flight Type soul masters—
An aerial firefighting squad.
A fire-starting squad.
A thunder-and-lightning squad.
A flying sand and rolling stones squad.
Defense Type: beast Martial Soul Possession strengthened defense, while tool Martial Souls, such as shields, directly increased defensive power.
They were more suitable for ordinary soldiers, improving their survival rate on the battlefield.
Special Healing Type:
For example, the Nine Heart Begonia! The characteristic of this Martial Soul was that no matter how many spirit rings it had, it possessed only one soul skill: an area-wide group healing skill whose effectiveness could be controlled at will.
Lin Hai guessed that its core healing ability came from the Martial Soul itself, while spirit rings were only used to break through bottlenecks!
If this guess was correct, the Nine Heart Begonia would become the best artificial Martial Soul.
After all, it was the Number One Healing Spirit on the Continent. Just imagine it—large numbers of warriors with Nine Heart Begonia Martial Souls appearing on the battlefield...
With Jade Phosphorus absent, who could contend with them? They could be called an "undying" legion!
There was another type of Martial Soul that was also highly suitable.
It was a Martial Soul like the Clear Sky Hammer, one that came with matching Self-Created Soul Skills, provided he could get his hands on the Clear Sky Nine Absolute and Disorder Splitting Wind Hammer.
As for the Great Sumeru Hammer, forget it. There were no rings to detonate.
Martial Spirit Pills had another use: impersonating members of particular factions. The effect depended on how one used them—
Infiltrating the enemy carried risks. After all, illegitimate children were not so easy to impersonate.
But pretending to be a member of some faction and going out to stir up hatred was much easier.
The pills were good, but their creator had no use for them.
He could not use Spirit Ring Pills. As for Martial Spirit Pills, heh... the instant a new Martial Soul formed, it would immediately be crushed by the Demon God Martial Soul.
The pill's quality-ignoring addition mechanism simply did not work on him at all.
Lin Hai could only say... there was nothing he could do about it.
Compared with Oscar's Mirror Sausage, Martial Spirit Pills had the disadvantage of lacking soul skills, but the advantages of permanence and requiring no labor.
Although they could not replicate one's own Martial Soul, his guess regarding the Nine Heart Begonia gave Lin Hai a trace of hope.
He told Bibi Dong everything he had discovered, only concealing his speculation about the Nine Heart Begonia Martial Soul.
Life was hard enough; no need to expose it. The Ye Family was miserable enough already. Turning them into a mobile blood bank too? That would be far too unkind.
Of course, if his guess proved true, taking a small amount of blood to arm those around him would not be a problem.
After all, refining one Martial Spirit Pill required only a single drop of blood.
He was not worried that Bibi Dong would think of it herself and directly make a move against the Ye Family. This matter could not bypass him.
He firmly believed that, given how highly his teacher regarded him, if she had such thoughts, she would consult him first.
Besides, the Ye Family differed from ordinary small and medium-sized clans. Their Martial Soul Curse made their descendants highly watched, and their network of connections was troublesome as well.
His research into sensitivity testing had ended in failure, but handing it over to the Bu Yuan Cauldron had doubled the results.
—Human effort could never rival heaven's favor.
Fortunately, he was the one favored by heaven. With a cauldron in hand, the world was his.
Lin Hai did not dwell on it either. "Failure" is the mother of "success." If my cauldron succeeds, then I succeed.
The moment he embraced Lying Flat, heaven and earth instantly widened!
Yet at this moment, Hu Liena, the best person to play along with him, was absent. His exhilaration instantly turned into a total letdown—first day without Nana, and he missed her!
"Teacher."
Lin Hai restrained some of his smugness.
"These two kinds of pills can only be refined by me in the entire continent. Tell me, if Spirit Hall controls them... would we still need to worry about failing to recruit those arrogant elite soul masters?"
At this moment, Bibi Dong's thoughts had long since moved beyond recruiting soul masters.
Once again, she was stunned by this little disciple's unrestrained ideas and the heaven-defying power of that mysterious little cauldron.
This little bastard's spirit rings... every single one was more astonishing than the last.
As the thought flashed through her mind, Bibi Dong even began to imagine:
By the day he became a Titled Douluo, would she still need to bother recruiting soul masters? Bringing him along to sweep through the two great empires would hardly be difficult...
Furthermore, with these two kinds of pills, even without recruiting independent soul masters, Spirit Hall's current strength could increase by several tenths.
In terms of combat power alone, it could increase by at least one "Heaven Dou Empire."
Her second Martial Soul, which had yet to receive any spirit rings, flashed through her mind, and a thought arose:
Why not have this boy refine several Ninety-Thousand-Year Spider Emperor Spirit Ring Pills for me right now?
However, the Pope's rationality swiftly suppressed this impulse.
With this boy's abilities, breaking through the bottleneck of Hundred-Thousand-Year Spirit Ring Pills was likely only a matter of time.
Hundred-thousand-year spirit rings... were worth waiting for.
As for whether he could give her a Third Martial Soul, that required further consideration.
Bibi Dong knew her own circumstances were special. Going from one Martial Soul to two without issue did not mean going from two to three would be equally safe.
She took a deep breath and suppressed her surging emotions. Her phoenix eyes were as deep as an abyss as she stared at Lin Hai, her voice carrying unprecedented gravity.
"Other than me, who else knows of this ability?"
Lin Hai grinned and answered decisively, "Only you, Teacher."
A nearly imperceptible trace of satisfaction flashed through Bibi Dong's eyes as she nodded.
"Very good. This matter is top secret and must not reach a third person's ears! If there is a need in the future, I will have someone secretly deliver the necessary materials to you, along with the required Spirit Ring Age."
Her tone eased slightly, but her authority remained unquestionable. "This is not a restriction. It is to protect you!"
"Such an ability is enough to drive the two great empires and every major sect mad, making them take desperate risks. It could even... make them cast aside their old grudges and join forces to strike back!"
