Roy is not in a hurry about the Dragon Ball, after all, this matter is not something he can control, and he has a lot to do now.

First of all, the first one is to be familiar with the environment of this low-level abyss world, especially the Castlevania City called Black Shine City, Roy still has to figure out what this city can bring to him.

A castlevania, for the upper demon, is not only a symbol of status, from the lower demon all the way up, Roy is no longer the kind of wild state that just finds a cave and uses it as a lair, in fact, if you look at it from another aspect, this architectural style of Castlevania also happens to prove that the demon race also has its own aesthetic and artistic senses, although this kind of demonic art is very terrifying and mad in the eyes of other races, but this is a proof of intelligence after all.

The name Black Yao City may be named after the building materials of this Castlevania, and those puppets who serve Castlevania will set off step by step every day to mine all kinds of ores in the mines included in Castlevania.

But despite occupying this castlevania, Roy didn't really care much, because for him, the city was not suitable for replanting the Red Sea Egg!

There's no way, this low-level abyss world is basically shared by the higher-level demons, if Roy plants the Red Sea Egg in this city with his front foot, maybe the hind foot will be discovered by other higher-level demons, Lilith is also a famous demon king in the abyss world, and her number of doppelgangers is estimated to be quite large, if someone makes a small report to Lilith, Roy may be in trouble.

Therefore, in Roy's expectations, it is best to wait until he becomes a demon lord and has his own alien realm, and then plant the Red Sea Egg.

This time to the Dark Bloodlines World, in fact, the biggest gain is not the number of millions of souls, but this Red Sea egg, and at the same time, this made Roy realize one thing, that is, the ten thousand worlds connected to the abyss, because they have their own development process, so they often give birth to some very special things, these things may be naturally generated, or they may be long before other intelligent species, these things or items, if they can be used flexibly, may be able to bring great benefits to Roy.

Just like this Red Sea Egg, it allows Roy to spend a small amount of soul to copy a clone with the same attributes as his body, which virtually saves Roy a lot of soul consumption, because if Roy does this through the system, the number of souls required cannot even be estimated by himself.

Although the system father is omnipotent, the souls that Roy can obtain are always limited, how to strengthen himself with a higher cost performance is a problem that Roy needs to consider, if he can go to other worlds in the future, obtain and collect special items in these worlds, wouldn't it be equivalent to canceling out a large number of souls?

In the past, in fact, Roy didn't think about these problems, but at that time, Roy's strength couldn't keep up, and he might not be able to get it if he wanted to, but with the improvement of his strength, he could also try to seek these things.

For example, the invincible world of heroes that Roy plans to go to next, there are many artifacts and treasures in that world, and if you can get a few and bring them back, it can also be the same as improving your strength.

This time, I went to the Dark Bloods world for so long, and when I came back, I found that the fat tiger was bullied by a fire demon, which made Roy also realize that it was time to improve the power of the fat tiger, as a pet created by himself, Roy's trust in it can be said to be higher than that of Juliel, and it happened that this time in the dark bloodlines world also hunted a lot of angels and got a lot of holy souls, these holy souls are not very useful for Roy, and there are fewer souls like Yuriel, It is impossible to use all of them to make fallen angel souls, it is better to use them for Fat Tiger, it just so happens that it was originally created from the fragments of Divine Souls, and these angel souls should be very effective for Fat Tiger.

So, after settling down, Roy began to think about how to promote Fat Tiger.

These angel souls, of course, are not directly eaten by the fat tiger, but Roy intends to use them to transform the fat tiger and redefine the attributes of the fat tiger.

As a three-headed dog of hell, Fat Tiger knows how to use three different elemental powers, but Roy actually realizes that it is not of much use to Fat Tiger to develop from the point of elemental powers.

The Fat Tiger's fighting style is inherently biased towards beasts, so it should evolve in the direction of a true monster and strangle enemies with its unmatched strength and strength.

Thinking of this, Roy couldn't help but think of the giant wolf Fenrir in Norse mythology, as well as the earthly giant python Yermungad, if the fat tiger's size can also grow very huge, hundreds of meters or even a height of one or two thousand meters, then how powerful will it be in the flesh!? At that time, let alone the demon lord, the demon king will probably be able to fly with one claw, right?

After thinking it through, Roy decided that the transformation of the Fat Tiger would start with its size and pure muscle strength, supplemented by extremely strong fur or scale armor as a defense, and directly turn the Fat Tiger into a Titan Cerberus!

If this is described in the terminology of the game, it is intended to transform the fat tiger into a super MT, and it just so happens that Julil's flame has a revival effect, which can be regarded as healing, and with Roy's mage turret, a small offensive and defensive battle group will be formed.

This transformation was soon put on the agenda, and Roy opened the attribute interface of the fat tiger, consumed the angel soul and a large number of ordinary souls, and made modifications to the attributes of the fat tiger.

The main changes are as follows:

[Strength Enhancement]: Every time the soul is devoured and the individual grows, the individual's power will be greatly strengthened.

[Active Enhancement]: Same as above.

[Agility Enhancement]: Same as above

[Iron Body]: Every time this creature grows, it will greatly enhance its physical and magical defenses on the surface.

[Infinite Growth]: The size of this creature is no longer limited.

The other attributes did not move, but the addition of these four attributes not only consumed the angel soul in Roy's hand, but also allowed him to spend more than 300,000 ordinary souls at once, and Roy's last remaining soul was not much left.

But the effect is also extremely amazing, when the attribute transformation is completed, the fat tiger who has been following Roy suddenly fell into a deep sleep, which scared Juliel, and thought that something was wrong with the fat tiger.

As a result, Roy calmly told her not to be impatient, and issued an order to the demon puppets in Black Shine City to go out to hunt monsters in large quantities and collect blood food.

The fat tiger hibernate for the first time for a total of seven days, and by the time it woke up, its size had increased by about 30% compared to the beginning, and then its three heads began a round of ferocious eating, and the tons of monster corpses collected by the demon puppets were all gnawed by it.

The growth of the fat tiger can be carried out by devouring flesh and blood, and it can also be carried out by devouring the soul, which is quite easy for Roy to raise, because if the blood and food are insufficient, Roy can also feed it the soul directly.

After eating, the fat tiger entered a dormant state again, and during this period, the fat tiger's body was growing at a speed visible to the naked eye, Roy could feel that the cells in all parts of the fat tiger's body were in a state of vigorous division, proliferating rapidly, but this proliferation was still within a controllable range, but it did not make the fat tiger's body become bloody.

Roy didn't know that Fat Tiger's growth would slow down after several rounds, but he didn't slack off, and continued to let the demon puppets get blood food back, and even he and Juliel went out to kill all the monsters within a hundred kilometers of Black Yao City.

Not only did these monsters have to contribute flesh and blood, but their souls have also been fed to the fat tiger, and Roy wants to see how huge the fat tiger can grow if he continues to grow like this.

The fat tiger hibernates when he is full, wakes up and eats violently, which lasted for seven rounds, and it took about fifty days in total, during which Bainia, the succubus, contacted Roy again, but Roy didn't bother to pay attention to her, and directly rejected her proposal to join forces.

And by the time the seven rounds of growth were completed, the size of the fat tiger had become a bit beyond Roy's imagination!

The current fat tiger, when standing on the ground, is more than six meters tall, and the body length is more than thirty meters, the fur on his body is dark and shiny, hard and elastic, and he knows at a glance that he has a strong defensive power, in the attribute panel of the system, its strength and agility have reached more than 1700, which is higher than Roy's, and the activity is also more than 1400, but the magic power is only a few hundred points, and it has not received any growth.

What hasn't grown, maybe there's intelligence, and this stupid dog now finds that his owner, Roy, has become short in front of him, with three heads and six eyes full of bewilderment!

It may not have adapted to the change in its body size, and wanted to rub Roy to be coquettish, so it directly arched Roy and flew out! And its huge size is too huge for the space inside the Demon Castle, and it collapses the pillars in the castle with a casual wag of its tail......

So, Fat Tiger was kicked out to sleep by Roy, an unscrupulous master......

Fortunately, after seven rounds of continuous growth, the Fat Tiger's changes have finally slowed down, and it no longer needs to eat, which means that its next growth may be a longer interval.

Juliel witnessed the huge changes in the fat tiger from beginning to end, and it can be said that she was stunned, she can feel the magic power of the fat tiger, I am afraid that it is at most the level of the middle and lower levels, but such a huge size, and such a powerful power, now I am afraid that some high-level demons may not be able to win it, right!?

When Roy took her out for a walk on the back of a fat tiger, she asked Roy blankly, "How the hell did you do it?" Why do I always feel that your dog is as amazing as you as an owner? ”

"Haha, isn't that good?" Roy hugged her and laughed: "In the world of demons, only strong is capital!" Since you chose to leave Samael and follow me, then I must at least grow to the same height as Samael to be worthy of your attention, right? ”

"Yes!" Julielle looked back at Roy with her eyes fascinated and said, "My partner, you will become the most powerful demon in the Abyss World!" ”
