Nebula thought carefully for a while and decided that he still wanted to mine this wisdom crystal vein, but Nebula didn't have time to find any miners, nor did he have time to carry out ordinary mining step by step.

Well, that's all there is to do

Nebula intends to use the Rubik's Cube of the Air Explosion Technique to blast and mine this Wisdom Crystal Ore Vein, although doing so may cause some damage to the Wisdom Crystal Mother Ore, but at least it will not be in vain.

Nebula first used the sap of the kara tree to corrode some craters near the veins of the Wisdom Crystal. Of course, the Wisdom Crystal, which is a magic crystal, is not affected by the corrosive effects of the sap of the Kara tree.

Then carefully placed one or two Rubik's cubes of the Air Explosion Technique in these pits, the power of the tenth-level magic of the Air Explosion Technique is not weak, and if the source of magic power is enough, its power can also be greatly increased.

The Rubik's cubes in Nebula's hands that enhanced the airblast technique were almost comparable to small plastics/bombs.

These dozen or so Rubik's Cube to strengthen the Qi Explosion Technique were originally purchased by Nebula from the auction and were intended to be used as a one-time means of defense.

When fighting against invincible enemies, as long as you throw these Rubik's cubes and activate them with mental power, these Qi Explosion Techniques, which are comparable to level 50 magic, will explode at the same time, even if the enemy reaches level 70, they can be slightly blocked for a second or two.

A second or two is enough for Nebula to use the dress-up, in other words, these Rubik's cubes are prepared by the Nebula to buy time for his own dress-up.

In the face of ordinary enemies, there is no need for Nebula to use costume change at all, and when facing enemies above level seventy, if there is a slight negligence, he may be killed instantly, after all, the difference between a magister and an elemental mage is still very big.

That's why Nebula needs some defensive means that can resist Magister-level attacks, and strengthening the Rubik's Cube is just one of them, and it is not a loss to use it to mine the wisdom crystal vein.

After retreating to the end of this strange underwater cavern, Nebula used his spiritual power to open several Rubik's cubes that strengthened the airblast technique.

"Boom~~~~Boom~~~~" Violent explosions overlapped, and the cave suddenly shook for a while, and the gravel and dust on the top of the cave fell.

Probably as a result of the powerful explosion, the thick stone walls of the cave began to crack densely, making it look dangerous.

Instead of waiting for the smoke and dust in front of him to dissipate, Nebula raised its magic shield and broke directly into the smoke and dust in the sky.

Although Nebula can't see clearly in this smoke and dust, and even the wizard's eye used by magicians to detect doesn't have much effect, but Nebula has infinite spiritual power that ordinary magicians can't imagine, as long as Nebula casually sweeps the surroundings with his spiritual power, he can determine the surrounding environment, and probe the gravel scattered on the surface, which are ordinary stones, and which are wisdom crystal mother mines.

In less than a minute, Nebula finished scavenging the scattered wisdom crystal mother ore, although there was still a small part of the wisdom crystal ore left in the vein, but the vein at that depth was difficult to mine even with the Rubik's Cube of the enhanced air blast technique, so although Nebula was a little greedy, he still wisely gave up.

At this time, a "click~~~" sound suddenly sounded, and the cracks on the stone wall of the cave began to increase, and some slender water columns began to spray out from the cracks in the stone wall.

It seems that the pressure on the bottom of the sea is too great, when Nebula used the Rubik's Cube to strengthen the air explosion technique to mine the wisdom crystal ore before, the cracks on the stone wall were only very small, but due to the strong pressure of the seawater, there are more and more cracks, and it may not be long before the stone wall of this cave will be washed away by the seawater, and the seawater will fill the entire cave.

Thinking of this, Nebula hurriedly ran towards the exit.

When he ran to the front of the magic circle in the center of the cave, Nebula stopped.

Damn, I didn't expect it to be like this, I could have had enough time to crack this magic array, and there was not much difficulty at all, but now the time is very tight, and I can only take a risk once!!

Nebula stopped his frustration and took out an inscription pen with a strong magical halo from the spatial ring, Nebula held the inscription pen in his hand, drew a series of strange and strange inscriptions, and began to prepare to forcibly disarm this magic array.

In a few moments, the thickest column of water on the stone wall of the cave had become as thick as a leg, and the sea water had overflowed the waist of the nebula.

Nebula happened to have completed the drawing of the Restoration Inscription Magic Array at this time, and the Restoration Inscription Magic Array is an inscription magic array that belongs to the grandmaster level, which can restore and eliminate any inscription magic array below the grandmaster level, even if it is a master-level inscription magic array.

It's just that the drawing of this magic array is more cumbersome and difficult, and it requires a lot of grandmaster skills, and the restoration of the inscription magic array has very strict requirements for spiritual power, and if there is no strong spiritual power, it is impossible to insist on drawing to the end.

Although many grandmaster-level inscription masters knew and understood this Restoration Inscription Magic Array, they simply did not have the ability to draw it, and this Restoration Inscription Magic Array was once thought to be only able to draw by inscription masters.

Although it took a lot of time, Nebula finally had a thrilling way to disappear the magic array in front of him.

After the magic array that isolated the sea water was eliminated, the infinite sea water suddenly surged towards the nebula, and the nebula stood in a relatively narrow cave passage near the entrance of the cave, and used the maple leaf staff against the left and right ends of the passage.

After taking a deep breath, Nebula pressed his body against the Maple Leaf Staff, held the Maple Leaf Staff tightly, and let the raging water wash away, never letting go.

After the water flow calmed down, Nebula pinched an air ling, and the membrane barrier formed by the air ling quickly enveloped the nebula, and Nebula swam towards the entrance of the cave while gulping down the fresh air.

Presumably, Brad and Chiyura should have been waiting for them at the fork in the road at this time, because it was already a few minutes before the agreed time.

There shouldn't be much air left in their hands, so they should have already returned to the fork in the road, if they don't want to be drowning in the sea

★?????????????????? ★

Three minutes later, Nebula returned to the fork in the road.

But all he saw was Brad, and as for Chiyura's figure, he couldn't find it.

Could it be said

"Hey! Chiyura! Did you hear that!? Answer me quickly!! Quick Answer!! Hey" Nebula hurriedly used a special communicator in the water, calling desperately to Zhiyula.

Brad shook his head at Nebula and said, "Don't call him anymore, he's no longer here!" ”

"Gone? Could it be that he was given by those rabbits," Nebula asked Brad excitedly.

Brad pointed to the top of his head and said to Nebula, "He's already up, it looks like he's fighting fiercely with the rabbits of Black Wings, and when he came to the fork in the road, there was only one last one left, so I asked him to go up first, and I'll stay here and wait for you." ”

After hearing this, Nebula immediately breathed a sigh of relief, although Chiyura was nominally his entourage, but Nebula had always regarded Chiyura as his close companion, if Chiyura had any accidents, how would he explain to his sister Sehera?

Nebula didn't say much, just made a gesture to float, signaling Brad to swim up first, and wait until the shore for anything.

After a while, Nebula and Brad surfaced one after another and swam to the shore.

Dabo, Nora, Assers, and Chiyura hurried to the shore and helped Brad and Nebula ashore.

"Huh!? Lord Nebula! How did you get wet? Chiyura asked Nebula suspiciously.

You must know that after using Air Ling, the head can automatically form a circular membrane barrier, and there is a membrane that is close to the body.

Even after more than two hours underwater, Chiyura and Brad's clothes were not wet, at most they were armed with weapons, and when they fought outside the membrane, they just got some seawater.

Nebula only explained a few words, after all, the most important thing now is how the three of them found information in the many caves under the sea.

After returning to the Third Observatory, Nebula first dried himself and changed his clothes, and then asked Chiyura and Brad, "Ash, Brad, did you find any clues?" ”

After hearing Nebula's inquiry, Chiyura proudly took out three volumes of unknown instructions from the spatial ring and handed them to Nebula, while Brad took out three volumes of instructions from behind his back and handed them to Nebula as if he was playing a trick.

Nebula took out four more volumes of instructions from his spatial ring, and spread them out one by one and placed them on the table.

"Well~~~~ With so many clues, you should be able to find the ultimate purpose of the Black Wings, but the sentences written on the instruction book are very strange, and you can't read it anyway, I'm afraid it will be a code, and you probably have to read it in a special way to understand this code." Nebula scratched his head and said with a headache.

Dabao, Assers, Nora, Brad, and Chiyura read these secret instructions one after another, but they couldn't come to any correct conclusions for a while, and if the code was so easy to crack, it wouldn't be worthy of being called a code.

"So be it! Let's go back to the glacier observation headquarters first! Anyway, we already have enough evidence to prove the innocence of the walruses, and there are quite a few books in the library of the Glacier Observation Headquarters, where we may be able to find clues to the code. Nora suggested to the crowd.

Nebula, Chiyura, Brad and Axels all agreed, after all, blind speculation here is not a good way to solve the problem, back to the glacier observation headquarters, while looking for books and materials, everyone brainstormed, and they will definitely be able to find a way to decipher this code!!

Seeing that everyone had made up their minds, Dabao didn't hold back too much, but rolled these instructions into thin scrolls, tied them into a bundle with a thin rope, and solemnly handed the unknown instruction bundle to Xingyun's hand, and said: "These things should be able to prove the innocence of our walrus clan!" Adventurers, you've seen it too, those guys aren't of our race, are they!? Explain this to the Photan of the Headquarters, and give it to him, who is older and knows much more than we do, and who may be able to unravel these incomprehensible codes for you. ”

"Please help clear up any misunderstanding you have about our walrus!! Please, brave adventurers!! Dabao once again pleaded sincerely to Xingyun and the others.

Nebula nodded, anyway, he didn't have any prejudice against the Walrus clan, rather than let them continue to doubt each other, it was better to prove their innocence to the walrus clan.

In order to successfully find the culprit of the melting and rupturing of the glacier, it may be easier to gather the strength of the three tribes

(Merry Christmas everyone!!) It's Christmas again, and I hope you can have a good time!! ）
