About a few years ago, when Liu Zong had just dealt with the Dragon Graveyard, the Battleship Bone Dragon was the first powerful undead class that Liu Zong had ever produced.

However, after the training, all of them were taken away by the wreckage of the commander of the battleship bone dragon, and he took all the battleship bone dragons with one goal, to find an opportunity that could make the battleship bone dragon an undead race.

Later, Liu Zong did not wait for the return of the battleship bone dragons, even if he went to the Hellsea and walked against the Styx River for such a long time, they did not return.

Liu Zong could only see from the mission control table that the wreckage of the battleship bone dragon was in a state of being out of the mission, so as to make sure that they were still alive.

At the same time, every time a battleship bone dragon is trained in the Dragon Graveyard, it will take the initiative to disappear into the Dragon Graveyard, and Liu Zong can't even see a shadow.

Just when the number of troops under Liu Zong was getting smaller and smaller, and the enemy was getting stronger and stronger, the battleship bone dragons returned.

They also brought back a rather crucial thing, and this is the key to the transformation of the battleship bone dragon from an ordinary undead class that had just been researched into a complete undead race.

At the same time, compared to the situation of more than ten when they left before, the number of battleship bone dragons that came back this time was close to twenty-two, and under the leadership of the wreckage, they kept circling around the Canglong Fortress for half a day before returning to the Dragon Graveyard.

Liu Zong met these battleship bone dragons in the Constant Wing Abyss, and looking at a fist-sized blue gem taken out of the wreckage, Liu Zong asked with some confusion: "This is what you finally got after spending so many years and killing so many battleship bone dragons?" ”

The wreckage had already turned into a bronze humanoid at this time, which was exactly his ability, the bow of the ship was like a possession, for Liu Zong's question, his wreckage just nodded, and said with certainty: "This is useful for the entire race of battleship bone dragons." ”

The appearance of the battleship bone dragon is actually a moment in Liu Zong's brain, originally he only planned to send troops, but now it is possible to become a race, Liu Zong naturally wants to ask more.

For Liu Zong's question, the wreckage was naturally explained in detail, in fact, when Liu Zong studied the battleship bone dragon at the beginning, it was just to bypass the rule that the Dragon Graveyard could not train dragon undead, after all, the dragon corpses in the Dragon Cemetery all have owners, and if Liu Zong guards and steals himself, there will be fewer and fewer dragons waiting for death in the Dragon Cemetery.

So Liu Zong fell in love with things like sea ships, because sea ships often have ship elves, and the main trunk of the ship is called the keel, and if they are soaked in the sea for such a long time, they are also considered dead things, and it is naturally okay to use their bodies to build a bone dragon.

It turns out that Liu Zong's choice was right, he made a creature like a battleship bone dragon, and from the perspective of combat effectiveness, they are still relatively distinctive.

Originally, Yanagi was supposed to keep expanding the number of battleship bone dragons, but the wreckage succeeded in becoming followers, and he had another idea to make the battleship bone dragons a race, not a combat class.

So he went out with the battleship bone dragons, looking for a burial place in the underworld, looking for opportunities from inside.

In the end, he brought back such a blue gem to Liu Zong, and told Liu Zong that this was the chance of the battleship bone dragon.

Regarding the situation of the battleship bone dragon, in fact, Liu Zong knows that the real reason for restricting the number of battleship bone dragons is that the number of battleships that can be used to make bone dragons is relatively small.

The wreckage also understood this, so he went to find the burial place at sea, where the wreck ended, and maybe there would be something useful for the battleship bone dragon.

However, when the wreckage brought the battleship bone dragon here, it was considered to have gone through a lot of hardships, and the number of battleship bone dragons killed along the way exceeded a hundred, if it weren't for the dragon graveyard that would send every battleship bone dragon trained to be sent directly to the wreckage, maybe he wouldn't have been able to get anything.

It is also because of this battle again and again that the wreckage has discovered the problem of battleship bone dragons, most of which are made of sailboat wreckage, but sailing ships are large and small, commercial and adventure, and not all of them are warships.

The strength of the battleship bone dragon made of these sailboats will obviously be weaker than that of the battleship bone dragon made of battleships, and they are often directly cannon fodder as soon as they are on the field.

So when I arrived at the sea burial ground of the wreck, the wreckage had an idea, whether it would be possible to only challenge the ship to make a battleship bone dragon in the future, and the ordinary ship would change to a different direction.

Of course, the wreckage also understood that if Yanagi Sect was to be persuaded in this regard, two things must be done, the first was to ensure that those ships would not be wasted, and the second was that there was a source of a large number of warship wreckage.

It is precisely for this reason that they have traveled several more places and spent more time to get everything done.

Looking at the sapphire in front of him and listening to the explanation of the wreckage, Liu Zong nodded lightly in agreement, and at the same time knew the wreckage's thoughts.

That is the cultivation of bone dragons, Liu Zong's battleship bone dragons are still made of sailboats, but only the bone dragons transformed from battleships can be taken to the battlefield for the first time, and those bone dragons made with commercial or risky ships need to be cultivated for a period of time.

The way to do this is to devour the wreckage of non-sailing ships in the sea burial grounds.

Although there are many canoes and other things in the wreckage of these ships, there are also steel giants and the like, which would not have been transformed into bone dragons, but it is a waste for them to stay there, and in the end they can only become ghost ships or something, so it is better to simply smash them and use them to raise battleship bone dragons.

Liu Zong was also quite satisfied with the wreckage, because when the battleship bone dragon left, he also tried to change those steel giant ships into bone dragons or something, but for some reason it didn't work out in the end, but in terms of ghost dragons, Liu Zong once again made a more cerebral existence.

It's just that this kind of ghost dragon with more brains is quite troublesome to make, and so far Liu Zong has only made a total of three, so he is naturally reluctant to use it and transform it into followers.

Now that the battleship bone dragon has returned, and has also brought back the methods and ideas of batch training, Liu Zong is naturally quite happy.

He took the sapphire from the wreckage, walked to a small clearing near the Abyss of Constant Wings, and threw the sapphire down like that.

At the moment when the sapphire landed, a deep pool appeared, and this deep pool was connected to the Constant Wing Abyss, and every time there was a suitable ship transformed into a battleship bone dragon, it would be transferred to the Constant Wing Abyss, and at the same time, all the battleship bone dragons that were not made of battleships would enter the sea burial ground from here, where they would continue to grow until they reached the reinforcement standard of the battleship bone dragon.
