After looking up for it for a short time, Invincible felt a ray of light flash from the corner of his eye, and suddenly stopped.

With the familiarity of this light, it is easy to feel that this light is reflected by a mirror, and is not anything else.

What is in the crater that reflects light?

It's nothing more than crystals like gems that crystallize during eruptions! With his super memory, Invincible looked at the point where the light was reflected just now, and it was a mountain wall. He flew up, clawed his left hand, and grabbed it with one claw.

The hard mountain wall was inserted like tofu under his five fingers, and Invincible hung there with his left hand that grabbed into the mountain wall, and then searched carefully.

Just a glance, he found a little fiery red crystal on the mountain wall, and he smiled - sure enough, there was something! Let's hope this thing isn't too bad! In the original world, crystals and diamonds were the same crystals, but their prices were very different!

Invincible's right hand was forced, and in a few clicks, he dug up the stone next to the crystal, and the full picture of the crystal was finally revealed.

The crystal is about a prismatic crystal with a diameter of 5 centimeters and a length of 10 centimeters, and its color is red. Invincible stunned - ruby?! Not quite like that! It turns out that although the ruby in the world is also red, where is the red color of this prismatic crystal come vividly, as if a flame is burning in the hand, this crystal ...... It's glowing?!

Invincible played for a moment, casually took the crimson crystal into his arms, and then dug up on the stone wall where the crystal had just been dug up.

As expected, several smaller crimson crystals were dug up around the prismatic crystal, but the largest was only one-fifth the size of the prismatic crystal.

Invincible put them all away disapprehantly, and he was going to take these crimson crystals back and study them slowly.

After discovering the crimson crystal, Invincible never found anything special in the crater, so he completed the rest of the exploration work in less than half an hour, and went out of the crater to find a map.

…………

Tu Meng looked at the invincible red crystal with some doubts, and after a while, his eyes suddenly lit up, and he suddenly shouted: "Ao Jin is on top!" This thing can't be a fire crystal, right?! Such a big piece?! ”

Invincible searched in his mind and found information about the Fire Demon Crystal, and couldn't help but light up his eyes: "You mean, this is the magician's treasure, the Demon Crystal?!" ”

Tu Meng stammered a little excitedly: "Yes... Be! But...... I've never seen such a large piece of fire crystal! It's impossible! According to this volume, at least the Holy Rank Demonic Beast can condense a Magic Crystal of this size! Don't...... My lord, you just killed the first Holy Rank demonic beast?! Belch...... When I didn't ask! ”

Tu Meng suddenly remembered that he hadn't heard any noise at all just now, and he still believed that Invincible could kill a Saint-Rank Demonic Beast, but to quietly and silently kill a Saint-Rank Demonic Beast in just half an hour, it was simply a fantasy.

Even if the invincible is willing to fight hard, the Holy Rank Demonic Beast will not remain silent! It would be easy to send a Saint-rank magic at random, or a hand-to-hand Saint-rank Demonic Beast to shake the mountains, so it was impossible for the battle with the Saint-Rank Demonic Beast to be so quiet.

Invincible shook his head: "No! It's just that I dug it out on the mountain wall of the crater, and it should be a natural formation, not a magic crystal of a Saint-level demonic beast. ”

Tu Meng was stunned: "Could it be that I saw it wrong?!" But this is obviously a fire magic crystal! Hey, it's a pity that we Okin people can't sense the magic element, if there is a magician here, he can use the sense of the magic element to determine whether it is a fire magic crystal or not. ”

Invincible listened to this, and his heart moved: "You said that the magician can sense whether there is a magic element in this thing?" Tu Meng nodded yes. Invincible, who received an affirmative answer, immediately focused his attention on the crimson crystal in his hand, and after a moment, he couldn't help but smile lightly: "It should be right!" There's a strong aura in it...... Well, there's a lot of magic! I can feel it! ”

Tu Meng was speechless...... Invincible surprised him too much, he had gradually begun to become immune, and just asked blankly: "My lord, can you sense the magic element?!" ”

Invincible nodded.

Only he himself understood that what he perceived was not a magical element, but an aura! This dense aura that filled the whole of Oslo had been discovered when he first arrived, but it was not connected with the magic element, but after perceiving it at this moment, he found that the crystal in the red crystal in his hand was also full of aura, and compared to the aura of the air, the aura in the crystal was solidified as if it were substance, and it was full of scorching and beating sensations.

In this regard, Invincible couldn't help but have a thought: it seems that the aura he felt seems to have a lot to do with the magical elements that Oslo said!

However, there is an ancient saying in the Dragon Kingdom: A hundred streams face the sea, and ten thousand streams return to their ancestors! Everything in the world always follows a kind of dark rules to operate, and his martial arts should also be related to magic and fighting qi, but he who doesn't know much about the principles of magic and fighting qi can't find this connection for the time being, but he will definitely notice this in the future.

Teaching the world is not a way to make one's cultivation to the next level!

Tu Meng swallowed a mouthful of saliva with difficulty, and asked the invincible tentatively, "My lord,...... Shall we sell this Fire Crystal? ”

Invincible glanced at Tu Meng lightly: "Why did you sell it?" ”

Tu Meng wanted to say that he would buy food after selling the gold coins, but suddenly remembered that Invincible didn't seem to plan to buy food from the human kingdom again, so he didn't know what to say.

Invincible played with the crystal in his hand, and then said: "If this thing is really a fire magic crystal, according to the information you once mentioned to me, it has a great effect on magicians!"

Tu Meng muttered secretly in his heart: It's not very important, it's a very big effect! Such a large piece of Fire Demon Crystal, for a Fire Archmage, its effect can almost be equivalent to a Saint-level staff!

"Then we sold it, and it wouldn't be impossible! But...... Gotta sell for a good price! Invincible said softly.

Tu Meng looked at the invincible in a daze, and suddenly found that at this moment, the invincible eyes suddenly revealed an extremely terrifying light, if he had to use one word to describe it, he would choose the word "cunning"!

No!

Perhaps it should be described as "very cunning"!
