Su Yu told them about his discovery, many of them lived in the same city as Su Yu, so it was simple, send them directly to the "Black Dragon Giant City", and let them find it in the ninety-second "Tiankeng Forest" by themselves. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

As for the others that are not in the same city, it will be troublesome to find, and they can only be searched one by one like Su Yu.

In the past few days, Su Yu has accompanied them to the major giant cities and greeted them in advance, but fortunately, the leaders of these giant cities have returned Su Yu's face, and when they learned the situation, they were quite cooperative.

Of course, in the "Black Iron City", there are only a very few parents and relatives who can be found, and many other people are either born and raised in the "Black Iron World", or like the Black Warrior, they don't know how many years they have lived, and there are no parents to find, or like Kou Xiaowei, their parents and relatives have long been dead.

In the past few days, Su Yu has been accompanying his parents in the "Black Iron City", and occasionally enters his palace to cultivate.

Now Su Yu has cast a "absolute seal" on all sides of this palace, not afraid of breath leakage, he has now reached the level of the fourth order of gold, and he can't break through for the time being, but absorbing the power of thunder and lightning, but there is no hindrance, after reuniting with his relatives, Su Yu cherishes this life, and he knows more and more clearly that he must become stronger, so that he has enough strength to protect all this.

Now the thunder and lightning power in Su Yu's body, its highest voltage intensity, can already reach one billion volts, according to the estimation of Tezkat Lipoca, if it is a god who can control the thunder surname, its strongest power is only to reach the level of one billion volts.

Although a large amount of energy has been devoured and converted into a billion volts of thunder, the "Core of Chaos" is only a very small circle, which shows that the power converted into a billion volts of thunder and lightning has only lost a very small amount of energy from the "Core of Chaos".

However, as the power of thunder and lightning becomes stronger and stronger, the speed of absorbing the "Chaos Core" into lightning power is becoming slower and slower, and its evolutionary path is becoming longer and longer.

When it is said that the cultivation in the "Lost World" has not been spent all night, the time to absorb the core of chaos and transform it into the power of thunder and lightning will not be less than ten hours every day, and it has taken Su Yu nearly a year to increase the power of thunder and lightning to one billion volts, according to Tezkat Lipoca's estimates, if you want to make the power of thunder and lightning comparable to the level of Ada, or the totems of the ten major races, its voltage strength must reach at least 2 billion volts.

If you want to increase the power of thunder and lightning from 1 billion volts to 2 billion volts, the difficulty is at least ten to 100 times more difficult than the previous increase to 1 billion volts.

If it took Su Yu nearly a year to increase the power of thunder and lightning to 1 billion volts in the "Lost World", then if he wants to increase from 1 billion volts to 2 billion volts, it will take decades or even a hundred years to make it possible, and this is still in the best state and environment.

Su Yu absorbed the "Chaos Core" for a while, and felt that there was almost no progress in the slightest, for him now, the most lacking thing was time, if there was enough time, it took decades or a hundred years, in the case of having the "Chaos Core", with his ability, he could indeed easily reach the realm of matching the totem, but ...... In this chaotic world, I am afraid that he will not have decades or a hundred years to make him slowly become stronger.

Putting the "Chaos Core" into the storage ring, Tezkatly Lipoca's voice rang out in surprise: "Boy, what's wrong?" ”

Su Yu smiled slightly bitterly: "Now it is too slow to transform the energy of the Chaos Core like this, if you want to ascend to the realm of 2 billion volts you said, I am afraid that it will take decades, this is really too slow." ”

Tezkatliba muttered, "It's a bit of trouble to convert the energy of the Chaos Core into lightning that can be absorbed...... It's a pity that if you can directly find the purest thunder and lightning power, then you can fuse and absorb it much faster. ”

When Su Yu put the core of chaos into the storage ring, he accidentally saw the Huangquan skull inside, and couldn't help but take it out, and said, "Ada, teacher, you say, what is the mystery of this Huangquan skull?" ”

Ada: "When you are still a black iron warrior, you can absorb the energy of this Huangquan skull, although the speed is very slow, but now that you think about it, there is indeed a problem, if this is really the bone of a truly immortal god, how can it be absorbed by you who is still a black iron warrior?" ”

Su Yu snorted, a smile appeared on the corner of his mouth, and said, "This skull does have a problem, so I want to ......"

Ada, sensing his thoughts, was a little surprised, "You want to absorb this Huangquan skull?" Now that you know there's something wrong with this skull, you still ......."

"I have the power of will in my body, which can convert all kinds of energy, even if this skull is terrible or evil, it can't hurt me, and I always feel that there is something hidden in this skull...... Perhaps, the energy that can be absorbed on the surface is just a protective film, just like the 'lost world' sealed by the teacher's absolute seal. ”

Su Yu's words made Ada's groaning slightly, thinking of the magic of the huge will in his body, there was really no need to be afraid, and Ada's was now very curious about this Huangquan skull.

Su Yu was curious about this Huangquan skull, and there was a huge will in his body that was sleeping, and he even devoured the so-called most perfect "999" seed power, even if the Huangquan God really did something to this Huangquan skull, Su Yu didn't need to be afraid.

He took out the Huangquan skull, and as soon as his mind moved, his huge will immediately descended and hit the Huangquan skull.

In the past, he used this huge will to stimulate the power of the gods in this Huangquan skull, and it was very powerful to smash it out, but this time it was not to stimulate the power of this Huangquan skull, but to convert its energy into the power of thunder and lightning.

When Su Yu was still in the Black Iron Realm, and he didn't have a huge will to help, he could use his own power to slowly absorb the power of this Huangquan skull, not to mention that now that he had reached the demigod realm and had a huge will?

Giving an order to this huge will, the entire palace space in the absolute seal fluctuated slightly, with the devouring of the "999" seed power, the will power in Su Yu's body has become stronger and stronger, if this huge will was an ethereal power before, then now, this power has been faintly elusive, and its power is fused with the power of the most perfect seed "999", looming behind Su Yu, forming a faint transparent phantom.

It's just that this phantom has not yet been perfectly revealed, and only some lines can be faintly seen, and the only thing that is relatively clear is a dragon-like giant eye in its phantom line.

With the advent of the huge will, an endless stream of energy immediately gushed out from Huang Quan's skull, turned into the power of thunder and lightning, and fused into Su Yu's body, and then he gathered into the pair of golden wings behind him, and its speed was thousands of times easier than transforming the "Chaos Core".

However, the power of thunder and lightning transformed by this transformation is almost a drop in the sea for the thunder and lightning energy that Su Yu himself has now, just like one or two more drops of water in the sea, which cannot stir up the slightest wave.

With the continuous operation of the huge will, Su Yu and Ada's eyes were focused on the Huangquan skull in front of them, and they watched as the golden color on the surface of the skull slowly faded, as if a layer had been scraped off by something.

After the outer layer of gold slowly faded, a faint blue luster emanated.

"It's ......"

Ah Da, Tezkat Lipoka both showed a look of surprise, as the huge will continued to devour the power of the Yellow Springs skull, the shape of the skull gradually changed, and finally turned into a half blue skull.

The skull, as if carved out of blue jade, was hollow inside, only half of it was missing, and from the nose to the lower half, it now looked like a blue jade cylinder with two holes.

Su Yu reined in his huge will power, and the faint line-shaped phantom behind him also disappeared, looking at the half of the blue skull, Su Yu looked at Ada, and in each other's eyes, they all showed a look of surprise.

This blue half skull did not reveal any terrifying energy, but when it was placed here, there was a faint sense of treasure obscurity, which made Su Yu instinctively feel in his heart, this was an extraordinary product.

In his mind, Tezkatly Lipoca took a slight breath and said slowly, "The crown of the true demon...... It turns out that this is the true face of the True Demon Crown......"

Su Yu held the half of the blue skull in one hand and muttered, "Could it be that the so-called True Demon Crown that those demons are looking for is really this half of a skull?" Or is this the true face of Huangquan's skull? Ada, teacher, what do you think? ”

Tezkatliboca sighed, "This can't be the skull of the Yellow Springs God...... Boy, you must put this thing away, the so-called crown of the true devil...... It turned out to be ......"

At this moment, Su Yu was trying to use the power of will, he wanted to try whether the blue half of the skull could be absorbed, and he didn't want the huge will to just come, suddenly, this half of the blue skull actually reacted, and it was a "buzz" in an instant, and suddenly, one after another dazzling blue luster burst out, and the "huge will" that Su Yu had just used was bounced back.

"What?" Su Yu was taken aback, on this half of the blue skull, a huge figure had risen up, this figure was a phantom, half of it stood in this palace, and the other half stretched out of the palace, Su Yu was surprised, this phantom stretched out a hand, and grabbed Su Yu fiercely.

The huge will power that Su Yu had just used was bounced away, and it seemed to anger the power of will, and the phantom behind him suddenly protruded, and the dragon-like giant eye opened, and a pattern of "9" appeared inside, Su Yu's right hand stretched out, and the simple phantom arm behind him was also extended, and it was suddenly supported together with the phantom giant palm that suddenly appeared.

The two phantom palms pressed together, and immediately after, the whole palace "buzzed", and suddenly the ashes disappeared, and the flat sky disappeared cleanly.

The sound was not violent, and it didn't even alarm the other people in the "Black Iron City", this palace just disappeared suddenly, and the two phantoms also disappeared, leaving only the surprised Su Yu and Ada, as well as ...... With a "dang" sound, half of the blue skull fell to the ground.

"This thing ......" Su Yu picked up half of the skull on the ground, with an indescribable expression on his face, this blue skull actually had the power to resist the devouring of the power of his huge will, and what was the huge phantom just now?

It's a pity that the phantom is too big, Su Yu didn't see the whole picture, and it was very weak, so he didn't recognize the true appearance of this phantom.

"This skull, it's really weird......" Su Yu looked at this half of the skull, thinking about what happened just now, just at that moment, the power that appeared was not so amazing, but it was not easy to resist his huge will, especially, this was just a skull.

This skull is too strange.

Su Yu groaned, the palace disappeared into the air, although there was no major movement, but it was quickly discovered by others, attracting a cry of surprise. Su Yu saw that he was discovered by other people, so he put away this half of the blue skull and put it into the "storage ring", and now his doubts were that this half of the skull, was it the true face of Huangquan's skull, or was this the crown of the supreme true demon?

"City Lord, there are people outside asking to see-"

Su Yu looked at the palace that had disappeared from the sky, and shook his head secretly, although there was no powerful energy fluctuation or sound just now, but to make a palace so silent that nothing was left behind, such energy was absolutely terrifying.

Hearing a voice coming from in front of him, Su Yu raised his head in surprise, and in the main hall in front of him, he met with someone who came, and it was Feng Ming, the main city lord of the "Ocean Main City".

Feng Ming had an anxious and panicked expression, and as soon as he saw Su Yu, he shouted: "Su Yu, you must save Lei Lian." ”

Su Yu recognized Feng Ming, because of Lei Lian's face, she was about to salute her, and after hearing this, she was taken aback and lost her voice: "What did you say?" What happened to Leilian? ”

I thought to myself that Reliant was with her parents, and with her parents' abilities, what would happen? If something happens under the protection of her parents, it will definitely be in trouble.

Feng Ming was very anxious and said, "Su Yu, I also got the news just now, Lei Lian was taken away, it seems that ...... It seems that there will be a danger to her life, Su Yu, you must save her, I can think of someone who can save her now, and it is only you. ”

Su Yu took a deep breath, and a trace of cold sweat was already oozing from his forehead.
