The Dragon Knight signs a master-servant soul contract with the dragon to control all the dragons, while Amanda and Argos sign a soul contract with the leader of the dragon knights to control the strongest among the dragon knights.

This is already the safest means of control at present.

After all, the number of gods in the Machine Empire is limited, and if you sign a soul contract directly with the dragon, each god will have to sign a dozen contracts, and this does not take into account the greater number of dragons that may be captured in the future.

This is obviously unrealistic. Soul contracts, depending on the strength of the recipient's soul, are also limited in number.

Zhang Feng didn't want to exhaust the potential of the soul slaves that his subordinates could control at this stage.

Only control the strongest of the dragons, and the other dragons can still betray, but the dragon knight is different. They were originally human, and if the Machine Empire had given them enough benefits to be their powerful backers, they would not have betrayed.

Zhang Feng thought about it again, thinking that he could control all the more than 200 dragons in his hands by doing so, so he was completely relieved.

The remaining dragon corpses are also very precious materials.

The dragon is full of treasures. Dragon scales, dragon skin, dragon blood, dragon bones...... Each of them is something that a magician on the continent of Limec dreams of.

And these things, now, are very cheap and casually piled together, like a mountain of meat.

At the foot of Roshan, what made the magicians and alchemists feel distressed to death was the dragon blood stream condensed into the bubbling dragon blood.

Zhang Feng's plan is to find a bunch of space rings and store these dragon corpses, and I believe that if they are brought to the Gafulby auction house the next day, it will definitely cause a lot of turmoil.

It's too boring, Zhang Feng is a person who likes to be in the limelight very much. Bringing a bunch of dragon materials to the auction is really refreshing.

More importantly, if you exchange these things for the best power source or even life source you need, I believe that the chance of success is much greater.

Many magicians and nobles are not short of magic crystals, but they definitely will not lack the ** materials of the dragon.

While pondering, Albert Einstein came over and reported:

"Master, please give these dragon corpses to Einstein, who can use the dragon's skeleton to create a lesser biological battleship. ”

The biological warship is a kind of warship created after the Atlantean civilization developed to the level of cosmic civilization. The origin of the combat weapons of the Atlantean civilization is based on bionics.

After the development of cosmic civilization, the Atlanteans discovered countless kinds of cosmic creatures in space. These creatures can survive directly in outer space, and they are extremely powerful.

As a result, the intelligent and intelligent Atlanteans created a type of space battleship based on these creatures, and this kind of battleship has also become the main battleship after the Atlantean civilization has developed to an advanced stage, that is, a biological battleship.

Zhang Feng, who is the inheritor, naturally knows this information. Now that I heard that Einstein was able to build a second-class biological warship from a giant dragon skeleton, I was immediately interested.

"Why are you called a second-class biological warship?"

"Back to the master's words, because the battleship made from the dragon skeleton is the same as the biological warship, and can retain the combat surname of the original creature. However, with the current level of science and technology, the warships we build cannot be self-sufficient in energy, so I call them second-class biological warships. Einstein replied respectfully.

Zhang Feng nodded, it seems that the key problem is the energy problem. If the energy is not self-sufficient, the operation may be greatly limited, for example, once the base is destroyed, then, the remaining warships will soon lose energy and become an existence that can be slaughtered by others.

This is especially evident in cosmic warfare, where the battlefield is often separated by tens or even hundreds of light-years.

However, for now, Zhang Feng didn't think that any force on the Limek Continent could destroy all his base warships. That's not a problem.

"What about the combat power of the inferior biological warship?" Zhang Feng asked again.

"The subordinates are not sure for the time being. Wait for the prototype of the battleship to be produced and tested before it can be determined, but the subordinates are expected to be no worse than the living dragon. Einstein's voice was full of confidence.

"Okay! These dragon corpses are all handed over to you, if you can build a powerful inferior creature warship for our Machine Empire, then you will be the hero of my Machine Empire, and I will also give you a chance to advance. ”

Einstein must have built an inferior biological warship in the shortest possible time. Einstein's voice was full of fanaticism.

If the biggest pursuit of mechanical life is promotion, then there is another pursuit of scientific research mechanical life, that is, to research new achievements.

And now, the owner has given him enough dragon materials for his own research, and if he succeeds, he can also get a chance to advance, which is absolutely satisfying for Einstein.

"I'll leave the skins and tendons of a few dragons, and I'll leave the rest to you. Zhang Feng said.

"Master, Einstein only needs the dragon skeleton and the dragon crystal nucleus, as for the dragon skin, dragon tendons, and dragon blood, these things are not needed for the time being. Albert Einstein said respectfully.

Zhang Feng was happy in his heart, in this way, it would be considered a delay for the two.

Einstein got more than 200 dragon skeletons and left satisfied.

After defeating 500 giant dragons, Zhang Feng did not feel relaxed at all. Because he knew that this was just the vanguard of Dragon Island.

Dragon Island miscalculated the strength of the Machine Empire - to be precise, the speed at which the strength of the Machine Empire developed far beyond the comprehension of the Dragon Clan, when the green dragon Wilbur learned that a dragon had been enslaved and came to test it, the warriors of the Machine Empire were still mainly second-level, and high-level warriors were only Arnold, who was at the peak of the ninth level.

However, in just over a month, the average level of mechanical warriors in the Mechanical Empire has risen to level five. The number of high-level warriors has increased to more than a dozen, and among them there is a saint-level Arnold.

The huge gap in strength between the two stages led to a serious error in the judgment of Dragon Island, and it was only then that the 500 giant dragons were wiped out this time.

And after this battle, the strength of the Machine Empire has been completely exposed. When Dragon Island attacks again, it will definitely come out, and when the time comes, the Machine Empire may face the wrath of tens of thousands of dragons.

Thinking about this, Zhang Feng felt a heavy pressure in his heart.

We must enhance our strength as soon as possible! This is the most pressing task at present.

If the strength of the Machine Empire cannot be qualitatively improved before the arrival of the Dragon Island army, it is difficult to say whether the result can be won.

With Dragon Island as an imaginary enemy, the current production plan of the sub-base is all designated as long-range attack classes and demon fighters.

All sub-bases are in full swing, and all kinds of resources are continuously transformed into mechanical warriors.

Now, the number of sub-bases has risen to 80, and each sub-base is capable of making 500 mechanical warriors per day, and the number of new fighters per day in the mechanical empire has reached a terrifying 40,000.

With 40,000 fifth-level warriors every day, this terrifying speed, as long as there is enough time for development, the Machine Empire will definitely become the most powerful force on the continent.

And the tactics of the sea of soldiers are also Zhang Feng's battle plan!

Since it is impossible for the Machine Empire to confront the entire Dragon Island in terms of high-level warriors for the time being, then the only way to suppress the other party is to use absolute numerical superiority.

Of course, in terms of high-level fighters, Zhang Feng did not completely give up.

With more than 200 dragons' skins and tendons, Zhang Feng is more interested in the upcoming first-class auction of Jiafubi Auction House.

...... At this time, on Dragon Island, the patriarchs were in chaos.

The 500 Red Dragons, since entering the territory of the Raynal Empire, have completely lost contact with Dragon Island. It was as if it had evaporated from the world, which made the dragon clan patriarchs very incomprehensible.

How did they know that due to the existence of the electronic jamming platform, the Red Dragon Vanguard would not even be able to transmit messages when it was defeated.

"Grand Patriarch, we have used magic communication several times, but we have not been able to contact Castellus!" the metal dragon patriarch Bahamut had a gloomy face.

Great Patriarch Brian's brows also furrowed: "The place where Castellus lost contact was just after entering the Raynal Empire. We don't want to believe it, but we have to be prepared that it is very likely that Castellus and his people have fallen. Or, it was captured by the enemy. However, I prefer to believe in the former rather than the latter. ”

The Great Patriarch's words silenced the surroundings.

"However, the Great Patriarch, five hundred dragons, is enough to sweep away a human power on the Limec Continent. Even if several great sages of the human race made a concerted move, it would be impossible for them to fall collectively before they even had time to send the information back. It's hard to understand. Could it be that Castrous would be stupid enough to go to the central mountain range of the Great Forest of the Demon Domain to provoke those ancient beings?"

At the mention of the ancient beings in the central mountain range of the Great Forest of the Demon Domain, several giant dragons fell into calm again.

"Castrous is a wise man, he could not have done such a stupid thing. With his surname, he will hunt some demonic beasts in the Demon Domain Forest at most, but he will definitely grasp the proportions. From where Castellus and the others disappeared, we can surmise that all of this was done by the Machine Empire. Perhaps we underestimate the strength of this mysterious force. ”

The Great Patriarch's voice was like thunder, rumbling back and forth in the cave.

"No matter what the reason, no matter who the other party is, if he dares to hurt the 500 dragons of the Castellus clan, then he is ready to bear the wrath of my Dragon Island!"

This was the result of the first time he had been promoted to the Divine Dragon, which made the Great Patriarch Brian very angry.

"Gather all the clansmen in the clan, we must show absolute superiority and not give the enemy any respite!"

"Yes, Grand Patriarch!"
