There are very few substances in nature that can emit light on their own, only a few of them, and they are all radioactive materials.

Taking enriched uranium as an example, one gram of enriched uranium fission can release 2 * 10 to the 10th joule of energy, which is equivalent to 1.5 tons of anthracite for power generation, producing 5555.56 kilowatt-hours of electricity, which seems inconspicuous, but the energy produced can melt seven or eight tons of steel into molten iron, and can also burn people to ashes dozens of times.

Of course, if it were not for artificial fission, the half-life of uranium would be measured in hundreds of millions of years, and if one gram of uranium decayed naturally, it would take hundreds of millions of years to release half of the energy, and the energy released in the form of radiation every second was pitifully small and almost negligible.

And this spar, I don't know what kind of substance it is, but one thing is certain, it is impossible to be a radioactive substance, and it is estimated that it will not take a few years for the release of such a form of light and heat to consume the energy of this spar.

But then again, the light and heat released by this energy crystal is also thousands of times stronger than enriched uranium, and the weight is more than fifty grams, it is really difficult to say how much energy is contained in it, if you take into account the terrifying strength of the eighth-level mutant creature, as well as the huge size, Luo Yuan estimates that the energy it contains may not be much less than one gram of enriched uranium.

Luo Yuan put down the glass tube with a solemn face, this thing is too dangerous, let's wait until the unicorn is dealt with.

He carefully placed the glass tube into the box, closed it again, and tore open the carton with the spiral unicorn next to it.

Inside the carton is a nearly two-meter-long strip-shaped wooden box, the wooden box is dense and dark, shaped like gold and iron, even if it does not need to be identified, Luo Yuan can roughly estimate that it should be a dark blue level wood.

The wooden box has dried and dehydrated rattan bark tightly tied in circles, tightly sealed, impermeable, Luo Yuan tore it hard, and he couldn't tear it for a while, until he used his will to cut these tough rattans one by one.

He was just about to open the box, but his hand touched the gap in the box, and he felt that his fingers were slightly numb, like needle, he quickly withdrew his hand, and when he saw it, his face was suddenly surprised, and his fingers were full of fine red spots.

If it weren't for the toughness of my skin, I'm afraid I would have to bleed this time.

This single horn is so terrifying, this is still a dead thing cut off, and the power it exudes is less than half of the original, Luo Yuan can't imagine that when the single horn is still on the mutant beast, it will be such a terrible weapon, I am afraid that before it has been contacted, the opponent is already full of holes.

He was in his heart, he didn't dare to underestimate it anymore, his will was condensed, and his body seemed to be covered with a flexible film of will light, he gently opened the wooden box, his eyes narrowed subconsciously, if it wasn't for Luo Yuan's will to protect him in advance, I'm afraid he wouldn't be able to see it at all at this time. I saw that the whole white-gold unicorn was sharp, and there seemed to be an invisible force in the vagueness, which kept raging and splitting in the air, under this power, the wooden box under the unicorn had almost been eroded into a semi-arc, and a layer of fine sawdust like powder was thickly piled up underneath.

Compared with the real thing, the pictures on the website are far from showing the power of the unicorn.

Luo Yuan stretched out his hand and touched it on the unicorn, feeling the will that was constantly being consumed, his face couldn't help but show joy, although the original horse chopping knife was also sharp, but just the feeling, compared to this real manifestation of power, it was simply a drop in the bucket.

He performed an identification technique:

"Phantom Horse's Onehorn"

"Rarity: Dark green."

"Weight: 65kg."

"Additional Abilities: Tear, Bleed;"

"Comment: The Phantom Horse is the darling of speed, it has no fixed territory, it travels around as it pleases, and speed and the unicorn are the means by which it protects itself."

Luo Yuan took a look and found that the additional ability of the unicorn and the horse chopping knife were very compatible, the knife was already sharp, and the ability to be like other messy things was useless to Luo Yuan.

He drew his saber, the tip of the knife swallowing out of his will, and instead grasped it, and thrust it into the middle of the horn, using synthesis.

Gradually, the unicorn began to heat up, and then it was already a heat wave, and the white gold with the single horn as the center of the knife quickly faded, and countless powders fell one after another, and at the same time, the original black stripes on a white background also gradually flashed a trace of white gold, and an invisible power began to diffuse on the knife body.

As time passed, most of the horns gradually turned to ashes, and only a third could no longer be synthesized.

Luo Yuan pulled out the knife and looked at it, the entire horse chopping knife had turned into a real murder weapon at this time, the whole knife was sharp, implying coercion, just looking at it from a distance, it was like a needle prick, his mind moved, and the tearing sharpness of the knife body suddenly converged, and then condensed on the blade, a sharp force that was several times more powerful than the original unconscious emanation, cutting wildly in the air.

Looking at the wooden box that originally contained a single horn, the horse chopping knife waved lightly, the tip of the knife slashed above the wooden box, there was no contact at all, and even the distance between the two was a foot long, but something surprising happened, with the rapid swing of the horse chopping knife, the entire wooden box was silently divided into two halves.

The incision is smooth and delicate, and it looks like a mirror.

This condensed sharp force is half a meter long, extremely sharp, and after half a meter away, this force is not all gone, but gradually weakened, but the power is no longer enough to cut the wooden box.

Of course, if this is the case, this power is only an auxiliary force, and the sword formed by the will is several times sharper than it.

But Luo Yuan's experiment found that this kind of sharp power can complement each other with the will, with this sharp power, the will seems to have a skeleton support, not only more stable and sharp, but also the maximum distance has expanded to a distance of one meter and a half, and the will to be consumed more incredibly has been greatly reduced.

"Phantom Saber"

"Rarity: Dark Green;"

"Weight: 24kg;"

"Attack: 40-46;"

"Additional Ability 1: +3 Attack Speed;"

"Additional Ability 2: Tear (Passive) Its sharpness can easily cut through any object (medium effect)

"Additional Ability 3: Bleeding (Passive) It can continuously bleed wounds and cannot be cured.

"Comments: This is a horse chopping knife with mysterious powers, it is so sharp that no one can grasp it except its owner."

Looking at the powerful attribute in his mind, Luo Yuan looked happy, to a certain extent, this dark green level (level 7) unicorn was worth more than ordinary level 8 materials to Luo Yuan.

The only thing that is a little uncomfortable is that the knife is a little heavier, nearly fifty pounds, so that he, who is used to holding the original horse chopping knife, feels a little uncomfortable for a while, and needs to practice for a while to get used to it, except for this insignificant flaw, everything is perfect.

After synthesizing, there were still one-thirds of the unicorn left, and when Luo Yuan picked up the unicorn and was about to clean up the room, he suddenly sighed, and he found that the remaining unicorn, that kind of sharp power, had completely disappeared.

Could it be that they have all been integrated into the horse chopping knife? Or is the absorption of power by the horse chopping knife unlimited?

His expression was a little incredible, this was the first time he had noticed this situation, after all, when the horse chopping knife was synthesized, either the materials were limited, and there was nothing left after synthesis, or the ability was obscure, and it was impossible to judge just by appearance, so that he didn't pay attention to it before.

However, due to the lack of evidence, he couldn't judge for a while, so it seems that he can only pay attention to it later.

Luo Yuan controlled the horse chopping knife to its full strength, and it was classified as ordinary, and then inserted the scabbard and put it aside.

Looking at the small box next to him, his heart began to stir again, this kind of thing that can make people immediately powerful and powerful, if you don't study it immediately, it is really itching.

He reached out and opened the box, carefully taking the glass bottle out of it, the wax on the top of the bottle quickly erased, and the cork was pulled out of it.

In an instant, a coercion spread out, making Luo Yuan breathe, and his expression quickly became solemn, this coercion was probably less than what happened compared to the real eighth-level mutant beast, but even so, there was still a trace of depression in his heart.

He took a deep breath, he didn't know how powerful the real eighth-level mutant beast was, just a little thought about it made people despair from the bottom of his heart, and when the time came, I was afraid that he would not be able to get close with his momentum alone.

He shook his head, dispelling distracting thoughts, not daring to hesitate, this energy crystal is extremely easy to oxidize, once exposed to the air for too long, I am afraid that the effect will be greatly reduced.

In order to avoid accidents, a thin layer of will was instantly covered with his body, and then he quickly poured the crystal into his hand.

However, as soon as the palm and the crystal came into contact, the energy crystal began to tremble violently like a living thing, and at the same time, Luo Yuan's spirit was in a trance, and an invisible roar rose in his heart, and vaguely, it seemed to see an elegant, colorful giant beast, raising its head and roaring angrily.

Luo Yuan took a few steps back, and when he came back to his senses, he couldn't help but turn pale.

Unconsciously, most of the will has dissipated, and there is not much left, and the film of will on the body is almost difficult to maintain.

He looked down at the palm of his hand, and found that he had unconsciously held the crystal just now, he spread out his palm, and the energy crystal was still in his hand, but compared to the previous violent tremor that seemed to want to escape, at this time, the energy crystal was motionless, and the scene just now was like an illusion.

Luo Yuan exhaled softly, feeling a chill behind him, and it was only at this time that he realized that he was already soaking wet.

"What was going on just now?" His face was solemn, and he still had palpitations.

PS: I'm sorry to make it up next time, I'll make it up when I'm free on Sunday.
