The Force has not closed his eyes for more than 24 hours, and has experienced a lot of things, but he has not felt sleepy at all, but is inexplicably excited.

His house is on the first floor, and after opening the door and entering the house, he rummaged through the cabinets and found some food casually, and went directly into the basement.

The basement was very simple, and he had carved it out by himself, just so that he could have a quieter environment for his practice.

Lighting a wall lamp, sitting on the couch, picking up a small photo frame in the pile of debris next to it, an old man with an old face and a wrinkled face, with a smile on the corner of his mouth, seemed a little helpless.

As if it was a kind of evasion, the old man didn't leave a photo for himself, and even, after sixteen years of getting along day and night, he didn't even know his real name, and the household registration book was "the original old man", which was as casual as "Yuan Dali", and he was very sure that this was not his real name.

Two years ago, the old man himself knew, and the Force knew, that the old guy's time was running out.

Although he has been an old man for as long as he can remember, he has changed so much at that time, one day at a time.

The Force dragged him into a studio and asked the artist to draw a portrait of him, and the painter showed his helplessness at that time.

"Old man, I found out, I was really taken into the pit by you, I just hope that for the sake of me I have cooked for you for so many years, brought you bath water for so many years, and finally sent you to the end, I used my hard-earned money to buy you a good place in Ji'an Hall, and I went to see you every month...... For the sake of these parts, don't make me too miserable. ”

It is indeed cool to "knock down" the textbook with hard facts, but more than ten years of hard work can be tied with a free injection, which does not seem to be something to be proud of.

If he still maintains this efficiency in the future, then he can really only cry.

The frame was tucked into the clutter pile and pressed against an unnamed letterhead.

He removed one of the pendants from his neck.

An ordinary red rope, because it looks a little greasy because of perennial wear.

Tied to an object that resembles a glass bead, both in size and shape, it looks like a marble played with as a child, with a line of fine lines in the middle, and like the pupils of a feline.

When he was a child, he saw that the old man had this thing around his neck at all times and never left his body, so he asked in doubt.

He said: "One day I suddenly felt that I was short of decorations, and there were a few little kids pouting their butts playing marbles on the street corner, so I went to pick one up and beautified it with the rope braiding skills I had practiced as a child."

...... Hehe, wait until you're older, or wait until I'm dead. Otherwise, if you really lose it as an ordinary marble, then I will have to die of distress in advance!"

Two years ago, when the old man was leaving, he didn't babble about anything, he was very calm, and handed him the object that he didn't leave his body: "When the time is right, you can operate it according to the method of using secret refining objects." ”

"This is also a secret refiner?" Although sad, but also surprised, after all, it doesn't look like it.

The old man blinked, and finally said, "Well, that's right." ”

After saying that, he closed his eyes calmly.

......

At this moment, he carefully took out the "marble" from the red rope net pocket, held it in his hand, closed his eyes and breathed.

He told Guo Kai that he had done a talent test in advance, and he was not casually perfunctory.

He did it, and he was sure of two things.

He has indeed reached the first order of black iron.

Your own matching bit is one.

It is important to know that unless it is a dead person, no one has a zero match bit, and match bit one is the worst.

A little disappointed, but, after all, it is possible to refine a secret refining object with blood.

And the fact that he had reached the first order of black iron without the need for matrix injections also gave him confidence, perhaps his growth was not much dependent on the secret refiner.

Now, it's the right time.

It has been a breakthrough in cultivation for a while, but he has endured his curiosity until now, that is, he is waiting for high school graduation, although he trusts the old man, but the old guy is naturally a little "informal", he is afraid that the blood refining of this thing will reveal some abnormalities, and this period of time is when the most cultivators appear in the school, so he has endured it until now.

Calm down and take out a clean needle from the pile of debris next to you.

Soon, he drew a tube full of blood from his arm, and then looked at the small "marble" in his hand, suddenly stunned, and looked at the full tube of blood.

"Did I smoke a little too much?"

Well, it's all pumped, and it's impossible to send it back.

"You can give it a bath. ”

He aimed the tip of his needle at the marble, and when the first drop of blood touched the marble, before he could react, the marble flew up and shot towards his forehead.

"Ahh ”

With a scream, he instinctively wanted to dodge, such a speed, I am afraid that it can pierce his entire skull!

In the end, nothing happened.

He stretched out his hand and touched his forehead, but there was no hole, no blood, no pain, and no marbles.

"Drill ...... Got in?"

As he thought so, a series of messages flowed into his mind automatically.

[DNA verification passed, start to confirm the binding, start energy activation ......]

[Look for the grassroots energy source, start looking for ...... Discovery of biomass energy...... Bioelectric Energy ...... Biomagnetic ...... Psychic ...... Di Di Di, discover the mysterious factor ......]

[According to the priority sequence, the mysterious factor is the main energy source, and the spirit wave and biological energy are the auxiliary energy sources.] 】

[The source interface is expanded.] 】

After this series of information turbulence, a picture of nothingness appeared directly in his mind.

In the picture, there is a familiar "marble", more like a pupil hanging quietly, when his attention is concentrated, he naturally knows its name.

【Mystic Pupil】

Then, naturally, he understood that it was divided into two parts.

The middle line seemed to be a subtle line of half-squinted pupils, and when he focused his attention, another string of information was sent into his mind.

[Collection: Consumes the host's own mystical factors, biological energy, spirit waves and other energy, and can control the mystical factors inside other things to move in one place.] Growable. 】

This is a skill that can be activated and used as he pleases.

He focused his attention on the rest of the line beyond the vertical pupil.

Another string of information poured into his head.

[Insight: Consumes the host's own mystical factors, bioenergy, spirit waves and other energy, and can perceive information such as mystical factors, bioenergy, and spirit waves inside other things.] Growable. 】

It is also a new skill that can be activated at any time.

Then, another string of information flooded into my mind.

[Oh, boy, this is the plug-in I gave you, now I know that Lao Tzu didn't cheat you! Although this thing only has two functions, but, as long as it is used properly, it can also play flowers, which is enough for you to toss. As for how to use it, I know it, but you should figure it out for yourself. 】

Although it was only a piece of information, sound and visual effects automatically came to his mind, because only an old man would speak to him in this tone.

"Actually secretly left a message here, if I hadn't been refining blood, wouldn't I have known all along, really!"

When he came to his senses and savored it carefully, the impact it had brought him had just begun.

The impact was too strong and I felt dizzy.

"Is this really a secret refiner?"

I had never heard of such a reaction after the blood refining, and I remembered the old man's expression and tone that day...... As for the use of only one drop of blood, there is no discomfort in the body, and the rejection reaction seems to be ineffective, etc., are also strong evidence.

It's more like a technological artifact than a secret artifact.

This directly raises a new question, is this really made by human beings by means of science and technology? When?

In addition, a word that appeared many times in those messages also made him have some associations.

It is said in the textbook that the mystical factor is the mystical factor, which is the name of the same thing at different times.

125 years ago, there was a sudden X-factor in the universe, which shattered the original laws of physics, and at that time, the macroscopic impact had not yet appeared, and the great destruction had unfolded from the microscopic level, and finally destroyed most of the fruits of human intelligence, such as all the use of electrical energy, magnetic levitation, nuclear energy, the information age, artificial intelligence, ......

It is interesting to note that the more you are at the top of the scientific pyramid, the more fragile and vulnerable you are to collapse.

This "destruction" was not instantaneous, but lasted for a whole year, starting at the very top of the scientific pyramid and working its way down, when it finally stabilized, and the way human civilization used energy regressed to the age of combustion power.

This mysterious phenomenon caused a global panic, with countless people searching for answers, and eventually, everyone knew that there was a factor X in the universe.

The reason why it is X is because it was a pure black box for human beings at that time, without any understanding, except for mystery, it is still mysterious, so it is also called the "mystery factor".

With the passage of time, human beings have more and more understanding of the mysterious factor, and even because of it, Shengsheng has turned the original scientific and technological civilization to the path of cultivating civilization, opening up a path of power growth with the mysterious factor as the core.

The first human beings in the Black Iron Realm appeared, and mankind entered the Black Iron Age, and then the Bronze Age, the Silver Age, and the Golden Age.

A nascent path of cultivation from scratch is rushing forward under the efforts of all mankind, rushing all the way, and human beings are more and more aware of the mysterious factor.

Until someone broke through to gold, mankind entered the Upanishads from then on.

The mystical factor is finally no longer mysterious, so it was renamed the Upanishads factor, which is the most important node since the birth of the new spiritual civilization, which is clearly recorded in the textbooks, and happened 65 years ago.

Until now, mankind has been in the age of the Upanishads.

If it weren't for the deliberate bad taste, we can roughly know from this habit of using words that this thing is at least an antiquity from sixty-five years ago.

He didn't deliberately delve into the origin of this thing, and after thinking about it, he spent all his thoughts on those two "skills".

He was still very excited in his heart, as far as he knew, other cultivators needed to be at a higher level to have this harvest, but not at the Black Iron Realm.

Playing and pondering over and over again, he didn't know how much time it took, and when he was hungry and thirsty, he picked up the food and water prepared by him and stuffed it into his mouth, until his body finally couldn't support it anymore, and he fell asleep.
