There were many compartments inside the box, and inside the compartments were all kinds of solid and liquid items, and I rummaged through them, and quickly pulled out a piece of silver-white metal.

"Roar!" Nightmare roared, and although he didn't understand what I was bringing out, the creature instinct in the face of the threat still made him instinctively wary, and then the Nightmare rushed again, this time the Nightmare turned into a black fireball, but this time I had no wolf wood carving to resist.

"Come on, show you the power of science. I tossed the silver metal out.

"Flash!" I activated the magic on the silver metal, and then turned around like an ostrich and closed my eyes, if it really didn't work, I probably couldn't escape the fate of being knocked into flesh by the nightmare.

The whole tree hole suddenly brightened as day.

The Nightmare let out a terrible scream, like a ghost underground, full of pain and resentment. The nightmare's eyes bore the brunt of the attack, the pitch-black eyes directly turned into a white expanse, from which thick black water continued to flow, the pitch-black flames on the nightmare's body were quickly suppressed by the fierce white light, almost extinguished, and the nightmare's body also began to appear little by little white spots, and then as if corroded by the points of light, it expanded rapidly, as if countless arrows of light shot through this evil creature from the abyss at the same time.

Nightmare probably couldn't understand why such a strong white light suddenly appeared in a tree hole, it is estimated that even the bishop-level holy light technique is just this level, but although the holy light can cause damage to them, the main body of the holy light is protection, not harm. The main role of the Holy Light is to strengthen the defense of the Paladins of the Church, or as a means of recovery for the priests, the Holy Light is not so much to increase the damage of the undead and evil, and the chaotic creatures, but to repel them from the essential differences between the two sides, just like water and fire. However, this light was as strong and domineering as the scorching sun at noon, erasing all shadows, and such a light caused great damage to the nightmare in an instant.

"Bingo!" I couldn't help but breathe a sigh of relief when I heard the nightmare screaming, in fact, I still have doubts about whether my own method can cause damage to the undead creatures like nightmares, after all, the light of my own artificial means is fundamentally different from the holy light of the gods, or the sunlight shining by the sun, the first two can suppress and cause damage to the undead, it does not mean that my own artificial light can also cause damage.

In fact, his minimum requirement was to flash the nightmare's eyes to create opportunities, but he didn't expect the effect to be surprisingly good, and the bursting flash directly caused great damage to the nightmare.

Magnesium metal, the chemical symbol is Mg, the atomic number is 12, although it is the eighth most abundant element in the earth's crust, but the content is only 2%, in order to collect this piece of magnesium metal, he spent a lot of time in the Dia, when he was not familiar with the element manipulation, sometimes he could collect a little bit of pearl size all day. Moreover, magnesium metal has a property, it is a very active element, which means that as long as it is placed in the air for a short period of time, magnesium metal will be easily oxidized.

After doing a full day of day work, I finally made up my mind to buy a storage magic box, after all, there are still a lot of such unstable elements, whether it is to deepen the understanding of the elements, or to develop new uses for these elements, a stable storage device is a must, after all, this is not more advanced than the previous life, just to avoid oxidation reactions, it is estimated that you have to worry about a few heads.

Magnesium metal has many uses in previous lives, such as as making light and hard composite materials from aluminum-magnesium alloys, which are used in aerospace technology, however, the most well-known use is flash grenades. The reaction of magnesium metal when exposed to heat is to emit a strong light in an instant, which is used for military flashbangs, camera flashes, ornamental fireworks, and the destruction of evil undead creatures, etc., which is really a necessary metal for home travel.

I turned my head to look at the tragic state of the nightmare, and I was also secretly shocked in my heart, and at the same time felt a little pity, according to this look, half of the magnesium metal should be enough, it seems that I don't have to throw it all out, but I can save a small life and have already earned blood, and the next thing I should think about is how to end it.

I cautiously picked up the elven dagger and held my hands steady.

"Wind Walk. 」

In an instant, I sped past at a blister's speed.

"Roar. The nightmare seemed to notice the fluctuation of mana, looked at it with its white covered eyes, and roared in its mouth, and a pitch-black fireball flew fiercely.

"Swift!"

I fine-tuned the angle of the wind elemental under my feet, and the black fireball brushed directly past my side, the fiery stench irritating my nose and my hair as if it was about to be burned. However, I was unmoved, and still rushed forward, although this fireball seemed ferocious, but because I couldn't accurately judge my position, this fireball was completely inaccurate, and this attack could not even hold up a threat.

"Wind Blast!" I took a deep breath, gathered what was left, and worked hard to unleash the last of my magic.

I saw that the wind elemental quickly gathered and compressed into a visible entity, and then a wind explosion composed of dense air hit the nightmare's side like a giant's jab, and the attack that was easy for the nightmare to dodge was now knocked to the ground, and the flanks were exposed.

"Woohoo!" Nightmare writhed as it tried to stand up, but then it felt a small weight weigh on it.

"Come on, it's over!" I shouted, and then stabbed the dagger into the horse's belly, and the dagger went straight into the handle, and the whole tree cavity suddenly lost the light of the elven dagger, and I blinked unaccustomed to it, and then a dying force shook me off directly from the nightmare.

"Bump!" I slammed into the wall, spitting out a mouthful of blood.

Then, a magical and magnificent scene appeared.

I saw a glimmer of light gradually appear on the side of the nightmare, and then, like the morning light, the glimmer gradually became larger, and the morning sun rose, giving the earth the gift of equality, and the evil under the shadow hurriedly dodged, however, there was a shadow that was still stubbornly resisting.

Nightmare's flanks continue to flow out of pitch-black and thick liquid, but what causes the most damage is the light of the elven short sword in Nightmare's body, the existence is denied by the sun, and the equal soothing is like a highly poisonous?? The spikes made the nightmare writhe in pain, and the body continued to emit black smoke, and the light spots on its body seemed to expand rapidly as if echoing the rising sun.

Then, a bright light flashed.

The nightmare was torn to shreds by the light, turning into a cloud of black smoke and quickly disappearing without a trace.

I looked at the elven dagger that was still emitting a strong light, and I couldn't help but feel a little lucky, it seems that I was still too naïve, if that flash technique didn't cause enough damage to the nightmare, I'm afraid the dagger might not be able to kill it, after all, as a high-level undead creature, the energy level is almost the same level as the holy light, just like a small river can't stop the volcano, if you rely on the holy light to look down on the undead, then one day you will suffer a big loss, and I'm afraid it will cost you your life.

However, a sense of uneasiness still weighed down like a stone in my heart, and even after killing the nightmare, that uneasiness still did not disappear, but it grew stronger and stronger.

"Damn. I decided to trust my feelings, and resolutely took out the last bottle of healing potion and a bottle of magic potion, after drinking these two bottles, I am afraid that I will have to lie down for a long time, after all, potions are not omnipotent, and overdrawn physical and mental power will definitely pay a price, however, as long as there is life, it can always be compensated.

However, the heavens do not obey people's wishes.

A black light flashed, and the two bottles of potion burst with a sound, spilling two expensive water stains on the ground.

At this point, I suddenly realized where my anxiety was coming from.

Now that the Nightmare is dead, why does the elf still emit a bright light as if sensing a powerful evil?

A figure in pitch-black armor walked over step by step, only to see that the thing was wearing an old jet-black armor, the inside of the pointed helmet was dark, most of the spikes at the joints had been broken, and stained with various dark red stains, and there was a black long sword pinned to his waist, but the long sword had been eroded by the years into a pitted rusty iron sword, but the strong smell of blood and the heavy magic power emitted by the long sword showed that this was not an ordinary sword.

I saw that the figure was like a puppet that had not been oiled for a long time, and slowly moved to the elven short sword with a strange and unnatural posture.

At this time, the elven short sword emitted a more intense light than before, and the sword body was constantly shaking due to the approach of the undead, I don't know if it was battle intent or ...... Fear?

"Kah. 」

"Don't!" The pitch-black armor seemed to look at me, and then his footsteps fell, stepping on the sword of the elven short sword, and with a click, the refined and gorgeous, sharp and sacred short sword was trampled into scrap iron, and the white light quickly dimmed, and as the light dimmed, I seemed to feel the armor's gaze looking at me, cold and ruthless.
