The bearded immortal said: "Although your ruler is not very remarkable, but it can withstand the bombardment of my Qingtian thunder, it can be classified as an immortal weapon." The flow of ordinary Dao weapons had already collapsed under the bombardment of the blue sky thunder, and the non-immortal weapons were not enough to withstand its power. This ruler can withstand the enemy, even if it is not surprising, there is no supernatural amplification function, etc., it must be regarded as an immortal weapon. However, among the immortal weapons, it is the lowest category. ”

Su Aotian secretly thought that he was judging the grade of the treasure according to this, and he didn't know if this was his own opinion or the usual standard of the fairy world.

But he still didn't say what the Meteorite Iron Stone was, so Su Aotian continued to ask: "How do Immortal Friends know that my ruler is made of Meteorite Iron Stone?"

The bearded immortal looked at him twice, with slight doubts in his heart, and said, "It seems that the immortal friend really doesn't know what this meteorite iron stone is. Speaking of which, this thing is not a thing from the fairy world, but fell from the cosmic firmament to the fairy world. This was a long time ago, and a huge meteorite suddenly fell from the sky and landed on the thirty-third layer of the immortal realm. The meteorite was so big that it became a mountain range when it fell. In addition to its huge size, the meteorite was also extremely heavy, smashing the ground tens of thousands of feet deep into the earth at that time. ”

The bearded immortal gushed out, after the meteorite landed, it naturally caused a sensation, and the emperors of all parties led the powerful figures such as the immortal monarch and the immortal handsome under the same seat to study. After careful exploration, this huge meteorite was composed of a substance that had never existed in the fairy world, that is, it was not like earth, nor like iron, and finally it was simply called iron stone.

After some research, the immortals found that there was nothing surprising about this iron stone except that it was extremely hard. Naturally, some people thought of using it to refine the weapon, but after trying it, they found that the reason why this meteorite is so heavy is because the structure of this iron and stone is so tight that even the immortals who are cultivating are difficult to penetrate, and even the Emperor of Heaven can not infuse much when he exerts supreme magical powers.

In this way, although this iron stone can be melted, it cannot compress the aura inside it, engrave the magic circle, etc., and there is no value in refining. It has no value other than being hard.

But it was harder than any other material in the fairy world, and the immortals wondered if they could use this characteristic to refine weapons. However, this idea also quickly proved to be unworkable, because this iron stone did not blend with any materials in the immortal world, and could not contain the sharp golden qi, what kind of weapon could be refined?

Faced with such a mountain-like material, but unable to use it, the immortals were very frustrated. They studied it for a long time, and finally had to give up helplessly. The Emperor of Heaven thought that it occupied a place on the thirty-third layer of the immortal realm, and used his great mana to remove it, and he was reluctant to throw it to the bottom of the immortal realm, and finally put it at the boundary between the lower and upper levels, on the ninth layer of the immortal realm.

As for why it is said that the Measuring Heaven Ruler is refined by this meteorite iron stone, it is because after refining the meteorite iron stone, the Heavenly Emperors took off the huge and complex material with a dark surface, and the remaining meteorite iron stone is a green and jade-like substance like the Measuring Heaven Ruler. Since it can't be compressed into the Fadu, it is impossible to refine it into a jade talisman, and in the end, it will become an extremely hard jade material, and there is no other use.

Some immortals are not too troublesome, and they build houses with jade after refining meteorite iron, and make them into tables, chairs, benches and other things, which are also sturdy and durable, but they are really unique when used to make weapons. The magic weapon pursues supernatural powers, and the divine soldier pursues sharpness, even if it is to refine armor, it must be of any size, can be collected or released, and finally cannot be swayed all day long with an incomparably hard shell, then it will not become a turtle? Not to mention that such an armor that cannot be connected must have loopholes, so what protection function is there?

Therefore, the ultimate use of this meteorite iron stone is not too troublesome, and it is used as a material for construction and decoration, and it is occasionally used, but it is not used for refining. According to the bearded immortal, Su Aotian is the first to open the world.

Hearing him say this, Su Aotian couldn't help but feel a little strange, the measuring ruler can obviously absorb the aura of heaven and earth and evolve by himself?

It suddenly occurred to him that after coming to the immortal realm, the evolution of the measuring heaven ruler seemed to have been terminated, and he had not absorbed the immortal qi.

Su Aotian immediately instilled an immortal qi into the measuring ruler, and sure enough, as the bearded immortal said, the inside of the measuring ruler seemed to be saturated, and the immortal qi could not be injected!

Is it any wonder that the measuring scale has stopped evolving, and I wonder why it is so saturated?

The bearded immortal talked to Su Aotian for a long time, and finally tried to find out where he came from, Su Aotian didn't want to entangle with him anymore, so after politely refusing, he said goodbye and left.

He was aroused by the bearded immortal, and wanted to go to the ninth layer of the immortal realm to see the mountain of meteorite iron with his own eyes.

Along the way, he couldn't help but wonder, why in the Spirit Realm, in the Chengtian Continent, the Heaven Measuring Ruler could absorb the aura and evolve by itself, but when he reached the Immortal Realm, this evolution stopped?

Even if you feed it immortal qi, it can't do it, and the inside of the measuring scale seems to be saturated.

After thinking about it for a long time, he figured out a little clue, maybe it was because the quality of the aura in different environments was different.

At the beginning of the Chengtian Continent, the black, scorched wood-like thing that happened to be obtained seemed to be the original face of the Meteorite Iron Stone. The reason why it appeared in the Chengtian Continent must have been brought by the black-robed Heavenly Emperor and others or the people who pursued and killed them.

At that time, because he sensed that there was a lot of space in the meteorite iron stone, he had the idea of taking a picture of it on a whim. Subsequently, the performance of the measuring ruler was completely consistent with his induction, and it was indeed able to absorb the vitality to evolve.

However, the immortal energy of the immortal world is by no means comparable to the vitality and aura, and the gap in level is too big. A trace of immortal energy, if you compare it with vitality, it may be the gap between a drop of water and an ocean. The measuring ruler can absorb a large amount of vitality and aura, but it may only be able to absorb a small amount of immortal energy.

The immortal qi brought by the people of the immortal realm who remained in the Chengtian Continent and the Spirit Realm has become much thinner after a long time, and the measuring heaven ruler can also absorb a large amount. On the contrary, when he arrived in the fairy world, he was immersed in the pure and rich fairy qi all day long, and he was like a poor man who was used to eating rough food, facing a table of delicacies from the mountains and seas, and became uncomfortable and indigestible.

Thinking of this, Su Aotian desperately instilled immortal qi into the measuring ruler, and felt that with the increase of pressure, the measuring ruler could absorb a little immortal qi again, proving his guess, basically correct, the space inside the measuring ruler was saturated.

Since this is the case, let's find a way to expand the space inside the measuring scale, those Heavenly Emperors, don't they still understand this truth?

He didn't know that in fact, the question he was thinking about now had already been thought about by the Heavenly Emperors. The reason why I didn't do this was because it was too difficult to expand the space inside the Meteorite Iron Stone. Because this kind of meteorite that fell from the sky from the universe is too dense!

It is easy to imagine how difficult it is to expand the space inside such a compact object without destroying its appearance!

What's more, this meteorite iron stone is not ordinary hard, but so hard that even the Emperor of Heaven has to work hard to break off a piece of it!

And to expand the internal space, it is not enough cultivation to carry out, and the divine consciousness must also be very strong, otherwise how to grasp the power that is fine to the peak, not more nor less, a little more is destruction, and a little less is untouched?

He may feel strange when he does this, but it is not that difficult, and if he is a bystander, it is tantamount to ascending to the sky!

While thinking about the matter of the meteorite iron stone, Su Aotian let go of his divine sense and searched for the ascending channel. It took him more than half a year to find an entrance and rise to the ninth floor under pressure.

Mengxizhou made a series of jumps, and it took so long that Luo Yingsleeve couldn't help but feel a little surprised. Although similar experiences have not stopped since she came to Mengxi Boat, she has already gone from unsuitable to habitual to numb, but this time the leap made her feel that the time was indeed too long.

When Mengxizhou finally stopped, Luo Yingsleeve couldn't help but come to the bow of the boat, wanting to see where Tianji had come to so much. As soon as she came out, she was stunned, and under the blue night, the stars around her were dotted with beautiful brilliance. The stars are as small as fists, and big ones are like wine jars, as if they are around and within reach. Looking down, a bright and dazzling fireball emitted a dazzling light, and the sun was under the Dream Creek Boat!

This time-consuming and laborious leap actually came to the starry sky!

Luo Yingsleeve couldn't help but have a dreamlike feeling, is this real?

Tianji's expression was solemn, and the ten fingers of his hands flew up, quickly transforming countless legal decisions. A powerful wave slowly dispersed, enveloping the starry sky for tens of thousands of miles, and the edge was like water waves rippling slightly.

With the swing of these ripples, the starry sky in front of him gradually changed, and the blue-black vague outline began to be revealed, gradually becoming clear, Luo Yingsleeve's eyes widened, and his mouth opened involuntarily, this is a magnificent and tall building, a rolling house is presented, no, it is not an ordinary house, this is a palace!

Sweat oozed from Tianji's forehead, and he could see that he was already struggling. It makes an immortal monarch feel unsustainable, and you can imagine how many resources and effort it has taken to erect this prohibition. What a huge stroke this is, Luo Yingsleeve never thought that there would be someone who could place the ban in the starry sky!

Tianji finally lowered his arm tiredly, and the ripples generated by spatial fluctuations completely stopped. The starry sky had vanished, and in front of me was a vast land, a magnificent palace towering, and the group of people standing in front of it, as small as ants.
