The Demon Hunting Association, an organization that has existed for thousands of years, was established in a mountain range.
Through the efforts of countless people, this place had long been transformed into an impenetrable fortress.
Lin Feng led Su Bai, and after passing through various checkpoints, they finally entered the dungeon.
This dungeon had a total of three levels.
The first level was for detaining traitors of the Demon Hunting Association.
The second level held extremely dangerous desperadoes; not only Grandmasters but also quite a few Innate Grandmasters were imprisoned there.
And the third level was the destination for their trip, a place used to raise Yao Beasts.
Walking through the dungeon, the ground was solid and dry.
Oil lamps illuminated the walls at regular intervals, and there were even luminescent plants growing.
It lacked the usual damp and gloomy feeling of an underground area.
Su Bai had the most dealings with Lin Feng within the Demon Hunting Association and understood that this old man held a very high position.
The leader of the Demon Hunting Association was the Association Head, but the Association Head was constantly out searching for traces of Innate Yao Beasts to prevent such terrifying existences from threatening civilians.
Below the Association Head were three Vice Association Heads, and Lin Feng was one of them, which showed his strength and prestige.
"We've arrived," Lin Feng reminded Su Bai.
He then ordered a Martial Artist guarding the dungeon to bring out a Yao Beast.
Not long after, a Yao Beast wolf, half the height of a person, was dragged out.
"Lord Lin, this Yao Beast wolf has been fed for two years and still needs some time to grow into a mature body."
"If it fails the obedience test, it will be killed, so it's perfect to be your experimental Yao Beast."
Lin Feng nodded.
A sub-adult Yao Beast wolf indeed met his requirements.
He looked at the still unconscious Yao Beast wolf, which had been given a sleeping potion and wouldn't wake up for a while.
"Alright, I'll take this Yao Beast wolf."
"Yes."
They wouldn't conduct the experiment in the dungeon, as many dangerous existences were imprisoned there.
If the Yao Beast wolf went mad, it could easily cause unforeseen crises.
Lin Feng directly hoisted the Yao Beast wolf onto his shoulder, seemingly without any effort.
"Let's go, Su Xiaoyou, we're heading to the Martial Arts Arena now."
Upon arriving at the Martial Arts Arena and setting down the unconscious Yao Beast wolf, Lin Feng eagerly gave Su Bai a look.
It seemed this old man was not as calm as he appeared.
Su Bai took out a porcelain bottle and poured a Monster Beast Pill into her hand, then flicked it into the Yao Beast wolf's mouth.
As the Monster Beast Pill entered its mouth, both of them prepared for defense.
Immediately after, the Yao Beast wolf, which had been in a coma, suddenly opened its eyes.
It saw the two unfamiliar humans in front of it, and a hint of ferocity flickered in its eyes.
Then, its body's Aura rapidly climbed.
According to Su Bai's previous observation, this Yao Beast wolf, calculated by the cultivation level of the Immortal Realm, was only at the Qi Refining second level as a sub-adult.
Now, after feeding it a Monster Beast Pill, the Yao Beast wolf's Qi and blood rapidly increased.
Lin Feng's eyes widened at this, and besides surprise, there was a hint of wild joy on his face!
Since the Yao Beast wolf's strength could be improved, it meant that a Martial Artist's strength could also be improved by consuming it!
"Owooh!"
With a long wolf howl, the Yao Beast wolf's Aura finally began to stabilize.
Qi Refining third level.
Although the improvement wasn't much, it proved that the Medicinal Pill was effective!
Moreover, seeing its stable Aura without any trace of instability indicated that the Monster Beast Pill's effect was excellent.
It had already stabilized at the Qi Refining third Realm.
"Elder Lin, I still have two more here.
Looking at the Yao Beast wolf's condition, there seem to be no side effects.
Shall we try another one?"
As an Alchemist, Su Bai naturally wanted to understand all the functions of the Monster Beast Pill.
However, upon hearing Su Bai's words, Lin Feng's face showed a hint of hesitation.
Su Bai had only produced three of these Medicinal Pills.
If two were given to this beast, then only one would be left.
But since Su Bai wanted to continue testing the Monster Beast Pill, he couldn't refuse.
He could only nod with a touch of heartache.
"Alright, but if this beast eats another one, won't we lose control of it?" Lin Feng asked, because after the Yao Beast wolf's strength increased, it seemed to have the intention of challenging the two of them.
One of its paws was restlessly digging at the ground.
"No problem, this beast has just stabilized at the Grandmaster Realm.
Even if it improves further, it will at most reach Innate.
Are we two Innate afraid of it?"
"You're right, give it to it!"
As Lin Feng's words fell, Su Bai poured out another Monster Beast Pill from her hand and flicked it towards the Yao Beast wolf's mouth.
With a gulp, before the Yao Beast wolf could react, the Medicinal Pill had already entered its mouth.
"Wooh~"
The Yao Beast wolf let out a low, threatening growl.
Just as it was about to attack Lin Feng and Su Bai, it adopted a running posture but then froze.
Then it began to let out pained howls.
The Yao Beast wolf's fur was tinged red, and a large amount of Qi and blood began to impact its flesh, causing its skin and muscles to crack.
Blood continuously seeped out.
But at the same time, the Yao Beast wolf's Aura began to rise again!
The Grandmaster Realm was Broken Through amidst the Yao Beast wolf's wails.
"This beast has advanced to Innate!" Before Su Bai could speak, Lin Feng's excited voice came from the side.
There was no worry in the old man's words about the Yao Beast wolf Breaking Through to Innate, nor was there any fear of the Yao Beast wolf's blood-soaked appearance at that moment.
There was only the pleasant surprise of the Yao Beast wolf continuously Breaking Through two Realms.
Shock, delight, ecstasy!
Lin Feng no longer maintained his calm expression.
Soon, the Yao Beast wolf's Breakthrough ended.
With the support of its immense Qi and blood, the wounds on the Yao Beast wolf, caused by continuously consuming Monster Beast Pills for Breakthrough, rapidly healed.
After reaching the Innate Realm, the Yao Beast wolf finally couldn't hold back anymore and immediately pounced on the two humans in front of it.
However, it had just advanced to Innate and still had injuries from the forced Breakthrough.
Facing Lin Feng and Su Bai, it couldn't gain any advantage.
Su Bai didn't even move.
Lin Feng was the first to leap out.
"Let this old man test your strength, hahaha!" Lin Feng roared, and his arms, as thick as logs, were already swung out, colliding head-on with the Yao Beast wolf.
In their initial exchange, Lin Feng tested the Yao Beast wolf's strength: it had just entered Innate.
"Hahaha, good, good Medicinal Pill!" Lin Feng's movements didn't stop as he continued to test.
Finally, after thirty moves, he landed a punch on the Yao Beast wolf's head.
With the force penetrating through, it was killed in one blow!
Lin Feng landed, ignoring the Yao Beast wolf.
He took quick steps and swiftly came before Su Bai.
"Su Xiaoyou! No, Alchemist Su! That Monster Beast Pill!"
Seeing the longing in Lin Feng's eyes, Su Bai shook her head slightly.
"Elder Lin, don't be so eager.
Let me thoroughly study this Yao Beast wolf first.
After all, it's a new Medicinal Pill.
Although it consumed many rare Spirit Medicine, it was only eaten by a Yao Beast.
It's hard to say if humans consuming it won't encounter unexpected issues."
Su Bai explained, and Lin Feng's mind, which had been tempted by the prospect of Breaking Through to Innate, calmed down a little.
Looking at the Yao Beast wolf's still blood-stained fur, he also nodded.
After this Yao Beast wolf's Breakthrough, its body was in such a state.
Although human Martial Artists also Cultivate Qi and blood, their physique certainly couldn't compare to a Yao Beast's.
Su Bai's words made a lot of sense.
"Phew, it seems I was too impatient."
"It's alright, Elder Lin.
Wanting to Breakthrough is the desire of many Martial Artists, but life is still the most important.
Of course, if it's confirmed that there are no major side effects, I will give you this last Monster Beast Pill first."
Having received Su Bai's promise, Lin Feng was completely relieved.
Then, he directly acted as a bodyguard.
The Medicinal Pill Su Bai was studying was the hope of Breaking Through to Innate Grandmaster.
Her personal safety must not be neglected!
Thinking of this, Lin Feng's tiger-like eyes scanned the surroundings.
