Starting from Ainz Ooal Gown, simultaneously traveling through time

Leylin gazed at the well-disciplined and well-equipped Royal Guard before him and made his own assessment.

Such an elite army, armed to the teeth, could, if used properly, truly create a battlefield miracle of "eight hundred defeating one hundred thousand".

The king's voice pulled him back from his thoughts: "By the way, don't distribute your remaining equipment indiscriminately. Although the quantity may seem enough for everyone to have one, not everyone is qualified or capable of making good use of these divine weapons you've found."

Leylin nodded to indicate that he understood: "I know. Those rewards given out before were both military merits and because the recipients were strong enough to truly control their power."

[Lower-level] Magical weapons do not impose strict "master-recognition" restrictions on the user, so there is no situation where they cannot be lifted or used.

However, if the user's own strength level is too low, they will not be able to unleash the full potential of the equipment and can only exert a small part of its effectiveness, which is tantamount to casting pearls before swine.

Therefore, Lei Lin has always adhered to the principle of "equipping the right gear with the right strength".

The "level" here is not the social class in Hindu Brahmanism, but an objective standard that measures the strength of an individual's foundation.

The king nodded with satisfaction. He knew that although his son's actions were sometimes unexpected, he was by no means reckless and knew his limits.

"What brings you here this time?" the king asked with a knowing smile, changing the subject. "You never come here without a reason."

Lei Lin feigned displeasure: "What are you saying? Can't I come to see you, Father, even if there's nothing wrong?"

"Don't give me that," the king said with a laugh, exposing his lie. "When have you ever come here without a 'surprise'? Tell me, what have you come up with this time? Is it related to those death row inmates we took away for drug testing?"

"Exactly." Leylin's joking expression vanished. "They have fulfilled their mission as experimental subjects."

Upon hearing this, the king's expression turned slightly serious: "You only mentioned testing the medicine at the time, and I didn't have time to ask in detail what kind of medicine it was, how effective it was, or if there were any problems."

He didn't care about the fate of those death row inmates; he was more concerned about whether his son's research was safe and controllable.

"The results are remarkable and have been verified, so it can be considered a phased success," Lei Lin said, reaching into his personal space to take out the familiar test tube.

Inside the test tube, the pale golden liquid rippled with a soft and mysterious glow, like a trapped ray of liquid sunlight, shimmering and beautiful enough to captivate the eye.

"This is it." Leylin handed the test tube to the king.

The king took the test tube, examining the magnificent potion within, which seemed to possess a life of its own, and asked curiously, "What is the effect of this beautiful potion?"

"Try it yourself and you'll see how effective it is," Lei Lin said, keeping everyone in suspense.

The king raised an eyebrow, looking at the potion with unknown ingredients. If someone else had presented it to him, he would never have tried it so easily.

But this was given to him by his own son, and this trust outweighed any caution towards the unknown.

He laughed and scolded, "You little rascal, are you trying to play a trick on me again?"

Nevertheless, the king decisively uncorked the bottle and drank the pale golden liquid in the test tube, which emitted a faint glow.

When the medicine entered my throat, I didn't feel anything special at first, but after a while, a gentle and lasting warm current spread from my stomach to my limbs and bones.

Leylin watched the king's changes slowly from the side, constantly checking with his observation magic.

Although numerous experiments have been conducted to ensure everything is correct, this is still his father, and he still needs the closest attention.

Leylin was always ready to act immediately should an accident occur.

Fortunately, nothing unexpected happened.

Under Leylin's careful observation, the king's health improved significantly, and his level increased by 1.

It improved from around level 35 to level 36.

In terms of rank, the king has now begun to enter the realm of the "abnormal".

However, the king himself only felt that his condition had improved a lot for the time being, and he did not pay much attention to the specific improvement in his strength.

"Hmm..." The king narrowed his eyes slightly, carefully sensing the changes in his body. "It feels... like my body is lighter, as if some invisible burden has been lifted."

He moved his arms around and did a few simple stretching exercises.

Time waits for no one. Although he takes good care of himself and his fighting ability has not declined significantly, he has indeed often felt that his energy is not as good as it was in his prime in recent years. A sense of fatigue of "not being able to do what he wants" occasionally quietly emerges.

However, at this moment, the sluggishness seemed to lessen, the fatigue was dispelled, and a long-lost vitality was faintly flowing in my veins.

"Excellent!" the king exclaimed. "This potion is so effective at boosting morale and relieving fatigue; even if it's only temporary, it's still a wonderful thing!"

Leylin shook his head and said seriously, "Father, you misunderstand. This is not a stimulant or enhancement potion that temporarily boosts your condition. Its full name is [Bloodline Evolution Potion], and its effect is to permanently enhance the user's base stats."

"A permanent upgrade?!" The king's smile froze instantly, replaced by extreme shock.

He had heard of various magical potions that could temporarily enhance strength, accelerate recovery, and even unleash potential, but "permanent enhancement"...

This almost touches upon the realm of legends and miracles.

The effects of medicine always wear off; that's common sense. But for an effect to solidify into one's own body is simply unheard of.

"That's right, a permanent upgrade," Leylin affirmed.

"Although the improvement in version 1.0 is currently limited, once this improvement is obtained, it will never disappear unless it suffers extreme and severe damage."

The king now truly realized the value of the empty test tube in his hand, and his heart was filled with shock.

A permanent upgrade, even if it's just a little bit, is enough to drive any warrior, mage, or even ordinary person crazy!

An idea naturally came to mind, and he asked eagerly, "Since the improvement is limited, can we achieve cumulative enhancement through multiple doses?"

Leylin shook his head again, shattering the king's illusions: "There's no such thing as a free lunch. The effects of the potion are unique; it only works the first time you take it. After that, no matter how much you drink, it's like drinking water, with no further strengthening effect."

Upon hearing this, the king was slightly disappointed, as the inability to repeatedly enhance an individual meant that the upper limit of individual enhancement was locked.

But he quickly adjusted his mindset, realizing that even a one-time permanent upgrade had immeasurable strategic value!

If it could be deployed to the army on a large scale, improving the basic strength of each soldier by "just a little bit", the combat power of the entire legion would achieve a qualitative leap!

Just as a little bit of sand can make a tower, and many small things can make a whole garment, the collective "little bit" can lead to earth-shattering changes!

"Wait, you just said it's called, 'Bloodline Evolution Potion'?"

The king astutely grasped the key words in the name: "Evolution, lineage—this name seems to have another meaning?"

"Exactly." Leylin explained in detail, "As the name suggests, it does not simply enhance strength on the surface. Its true working principle is to gently optimize and improve human beings from the most fundamental innate potential."

"More importantly, this optimized trait is hereditary. The offspring of the user will have a high chance of inheriting this enhanced and superior innate potential."

The king understood completely and fully grasped the terrifying significance of this potion, which was enough to change the fate of his race!

This is not just about strengthening individuals, but about improving the bloodline foundation of the entire ethnic group!

Just as the Inberia royal family has always encouraged the union of strong individuals in the hope of producing even stronger offspring, this potion achieves and accelerates this process in a more direct and controllable way!

"You..." The king took a deep breath, looking at his son with a complicated expression, his voice trembling slightly with excitement, "You really have created a potion that can shake the world."

Leylin remained calm, even somewhat modestly making that classic "little bit" gesture with his thumb and forefinger again: "At the moment, we can really only improve it by 'a little bit'."

The king shook his head solemnly: "Your little bit is like a ladder bestowed by heaven for hundreds of millions of ordinary people. It gives more people the opportunity to reach heights they could never have achieved in their entire lives."

He instantly thought of many things: perhaps more talented people would emerge from the common people as a result, and the potential of the entire kingdom would be enhanced.

Immediately afterwards, a strong sense of vigilance and protectiveness welled up inside me.

The king lowered his voice, his expression extremely grave: "Leylin, the existence of this potion must be classified as top secret! It must never be known to the outside world, especially not to those foreign races or enemy nations! You developed it independently, right? Everyone who knows about it…"

"Father, rest assured." Leylin understood the king's concerns and replied, "The people who knew about the experiment are all gone. The formula, the process, and the core principles are currently only fully understood by me. You are the first user who knows the whole story."

The king breathed a heavy sigh of relief, but the sharpness in his eyes remained undiminished.

Such a strategic resource, even a racial treasure, must be allocated with utmost care.

Almost instinctively, his first thought was to prioritize the use of the core members of the royal family and the absolutely loyal close relatives of the nobility, in order to ensure the stability and continuation of the monarchy.

This idea may seem selfish, but as a king, he must first consider the core interests of his family and the country.

In his mind, such a miraculous potion must have been extremely complicated and difficult to make, and its production must have been extremely rare.

"By the way," the king asked tentatively, mentally prepared to hear a single-digit number, "how much of this potion do you have in stock right now? Surely it's not just this one bottle I drank?"

Leylin stroked his chin, as if making a calculation, and then replied in a nonchalant tone, as if saying, "The weather's nice today":

"Oh, this? We've been working overtime for the past month and have produced a preliminary batch, but the quantity isn't large, only a little over 100,000 bottles."

The king's expression froze instantly, his eyes widened, and he wondered if he was hallucinating.

He opened his mouth, and after a long while, he managed to squeeze out a distorted gasp of surprise from his throat:

"How...how many?! More than 100,000...bottles?!"
