In fact, Rollin's idea was very simple, let the companion worm parasitize Caesar's stomach. The connection between the dragon and the Targaryen's master is inexplicable, but two of them are certain.

One: At the soul level, the ordinary spiritual communication shows that this connection is caused by the soul conjunction.

Two: Bloodline energy, the dragon egg will be activated by the bloodline energy in the Targaryen's body, and can be hatched and born.

Bloodline energy is different from magic, it lies dormant in the Targaryen's body, and it can't be mobilized at all. Rollin can only breathe dragon breath by saying the dragon spell in Valyrian.

Demon dragons are different from Targaryens, they are born magical creatures, the dragon blood in their bodies is hot, and that kind of strange bloodline energy is more active in the body of the demon dragon, if the Targaryen is compared to hidden, then the bloodline energy of the demon dragon is explicit.

Rollin used Caesar's blood to test and found that this domineering bloodline energy would repel and dissolve any magical power, and this energy was the fundamental reason why the demon dragon and Targaryen were free from demons.

The four-ring magic of the Children of the Forest, if it is a spell of pure energy, may not even be able to break Caesar's scales.

But these dwarves obviously chose spells in a targeted manner, and the powerful magic aura exploded, causing a terrifying thrust, even Caesar, who was more than ten meters long, was directly hit, and now he was lying half-naked in the dragon's nest on Qianmian Island, being served and fed, and had become a half-plant dragon...

But if this four-ring spell encounters the Black Death, the aura that promotes the spread may be violently broken, and the physical power reaches a point where it can ignore everything, what is the concept of a giant beast of more than two hundred meters, and now Harrenhal is about to be eaten poor.

Rollin retracted his thoughts, pricked his finger with his knife, letting his blood soak in his arms, and carefully placed the snail in the container.

The moment the worm falls into the blood, it is like a drop of water in a pan of oil, and the blood boils.

The snail floated in the blood and tumbled painfully, and this feeling was transmitted to Luo Lin synchronously, wiping the sweat from his forehead, Luo Lin stared at the fly snail intently, and recorded some important data with experimental notes in his hand.

Companion worms have magic in their bodies, and these magic powers are injected into the companion worm by the wizard during the contract to manipulate the abilities of the companion worm.

If you want the companion worm to survive in the stomach of the demon dragon, the first point is to remove the magic power from the companion worm's body, and the erosive nature of the dragon's blood is the best way, and the protection of Luo Lin can also ensure the safety of the snail.

As the magic power in the snail's body disappeared, Luo Lin realized that he was missing a talent for witchcraft, and his active evolution was gone. But in order for Caesar to be able to fly again, fly higher, worth!

Now use tweezers to pinch out the companion worm and put it in another cup full of blood, which is Caesar's dragon's blood, and the blood energy in it is even more violent than Rollin's.

This step will allow bloodline energy to replace mana, and after completing this step, the companion worm will be eligible to survive in the demon dragon's body.

As soon as the snail was placed in the blood of the demon dragon, there was a sharp pain, which made Luo Lin can't help but exhale in pain.

There was more bloodshot in Rollin's eyes, and the whole eyeball seemed to have turned into a bloody eye, he hadn't rested for too long, and the current pain stimulation was too terrifying.

The golden doji in Luo Lin's eyes spun and shrank rapidly, and the microvision was *150 times.

Done, done! ~ He looked forward to it from the bottom of his heart.

This precious and powerful companion worm cannot be lost here.

This is a snail, with infinite possibilities for evolution!

The Great Wizard of Grimm has achieved an inexplicably great existence with it.

Rollin was also lucky enough to get it, and there may never be a second one in the world.

The blood-colored energy infected the snail's body, dyeing the snail blood-red little by little.

Rollin swung his fist excitedly, and it was done!

"Prepare the boat and go to Qianmian Island!" Rollin immediately ordered the maid outside the door.

Hearing of the movement in the laboratory, the Ruhr Scholars rushed over, a historic moment, the first parasitic companion dragon was about to be born.

And it's a parasitic companion worm with such a powerful force, what kind of perverted monster will this create, everyone is looking forward to.

The boat sailing towards Qianmian Island.

"So the snail only has the most basic ability?" Maester Ruhr asked.

Luo Lin held the cup in his arms and nodded calmly, "Passive evolution, only this ability is left, but it is enough for Caesar to have it." ”

Maester Ruhr said with some regret:

"It's a pity that I didn't get to see another powerful sorcery of the fly snail, the 'Alien Force Field', with which the Great Wizard of Grimm once killed a legendary creature."

Luo Lin was silent, he also understood this witchcraft, the active evolution of the snail witchcraft relied on a force field, if this force field was controllable on the owner of the companion insect, if this force field was applied to another creature, then extremely terrifying results would occur.

Active Evolution Luo Lin has just developed to the second stage, and there is a third stage behind it, and after the third stage, this force field can be emitted outside the body, and the 'alienation force field' can be officially cultivated, and now everything is empty.

Luo Lin looked at the dragon's nest on Thousand Faces Island, but it was worth it, relatives were very important in Luo Lin's heart, and it was not comparable to a witchcraft.

There was a slight collision and the boat came to shore.

"Here we are, sir." The boatman opened the curtain and said.

"Hmm."

Rollin and Maester Ruhr headed straight for the Dragon's Lair.

At this time, Caesar was lying on his stomach in a wooden house made of fish beams, and some soldiers stood guard not far away.

The wounds on its body had begun to scar, and after it could not move freely, the demon dragon had a somewhat manic temper, and several of the servants in charge of feeding were bitten.

When Caesar found Rollin coming, he tried to struggle to his feet, but he didn't succeed, and instead fell to the ground, letting out a roar of pain.

Its ribcage was not protected by ribs, and the fall was 100% injurious to its internal organs.

"Caesar, don't move." Rollin hurriedly stepped forward to appease the dragon.

These days it struggled to get up, and every time it fell to the ground, which is why Caesar's injuries never healed.

Whining! ~ The dragon let out a pitiful whimper.

It wanted to move, it wanted to fly, it wanted to see its master, it wanted to run over and lick Rollin's face, but it couldn't.

Rollin wiped Caesar's forehead lightly, and waited for the dragon to calm down before taking out the cup.

"Don't move, understand?" Rollin said softly.

Through the psychic connection with the magic dragon, Rollin did not need the Valyrian dragon spell and directly ordered Caesar not to move.

"Don't squirm your throat either, remember the games we did before? 1、2、3。 ”

Luo Lin looked at Caesar's dark golden dragon's eye, and suddenly said:

"Wooden man!"

He quickly opened the dragon's kiss and poured the dragon's blood containing the fly snail into Caesar's throat.

The moment Caesar pronounced the word, his whole body froze, and only his pupils were spinning.

When it was born, it played this game with Aria and Rollin, and its body was conditioned.

Luo Lin sensed it, and the snail successfully climbed to the dragon's stomach and took up a sojourn.

The domineering dragon blood energy in the companion worm's body will protect it to survive safely in the dragon's stomach, and it can finally breathe a sigh of relief.

"Is it done?" Ruhr asked.

"Hmm." Rollin nodded slightly.

"Because Caesar has a soul connection with me, he can also indirectly communicate with the companion worm in his body, and the bloodline energy of the companion worm also comes from Caesar's body, and passive evolution will take effect from time to time."

A smile appeared on Rollin's face, and his tone became a little pleasant: "If Caesar's will is to walk and fly, this subconscious will constantly stimulate the fly snail to help it grow bones and restore its broken wings. ”

Ruhl pouted, "I'm afraid that this gluttonous will keep thinking about eating, and then grow a second mouth." ”

"Uh... It's really possible. Luo Lin was a little painful, and said helplessly: "My will is actually also linked to the snail, and I will interfere with its evolution when necessary." ”

"Let's go back to Harrenhal first, we should see the effect in a few days."

After returning to Harrenhal, Rollin had to find Theodore again, and the steelmaking method he had studied some time ago had to be put into production, and now Harrenhal had too many places to use money.

After rewarding the soldiers, Rollin's wallet was flattened again, so many huge fish beams and woods were good materials for repairing the castle, and the reconstruction of Wastestone City was on the agenda.

It is an important place, which is related to the construction and expansion of Luo Lin's power, and Luo Lin's next commodity also needs to be carried out in Wastestone City, he wants to make salt, and the production method of sea salt is actually very simple, what is missing is territory. And Wastestone City is an excellent salt farm.

The Iron People hope that you will not offend me, or the wrath of justice will come.

Thinking all the way, I unconsciously arrived at the Ghost Tower, separated from Master Ruhr, who lived on the top of the tower, and Theodore's two apprentices lived on the second floor of the tower.

He dragged Theodore to Harrenhal's forge room, where a dozen Braavos slave blacksmiths were pounding red iron blanks, and the sound of tintins was endless.

The work of these slaves is quite satisfying, and they are sweating and sweating to build weapons and armor, which can add some meat to them this month.

Theodore picked up a freshly made dagger and handed it to Rollin, standing respectfully aside.

This is Braavos's swordsmithing? It seems terrible.

"Don't you know how to do heat treatment?"

Rollin asked.

"What's that?"

Salhan, who is also the leading slave craftsman here, asked curiously.

Rollin glanced at Theodore, who shook his head, not understanding what Rollin was talking about.

At this time, a bronze-skinned man walked over and said loudly: "My lord, you are talking about 'normalizing' and 'annealing'. ”

The purpose of normalizing is to granulate the steel (crystallized structure).

In fact, each time the swordsmith heats a part of the blade, after forging, he changes not only the shape of the steel, but also the steel particles. When the steel is heated to a certain temperature, austenitization occurs (iron and carbon atoms begin to mix).

The steel is removed from the calciner and then cooled naturally. This reduces stress due to irregularities in the composition of the sword body and ensures consistency throughout the sword body particles.

Annealing is the process of allowing the steel to cool down slowly.

Usually, the steel is wrapped with an insulating material to ensure that the steel does not cool down quickly. The annealing process varies from a few hours to a day. The purpose of annealing is to make the steel soft for grinding and cutting.

Luo Lin nodded, it seems that these basic processes are the same as in the previous life, so it is much easier to continue to teach them the method of making 'stuffy steel'.

"Salhan and this—" Rollin pointed to the big man in front of him.

"My name, my name is Shon."

"Salhan and Shuster stay, and the others go out first." Luo Lin ordered, and when he saw that everyone was almost gone, he spoke: "Today I will teach you a steel-making method, and I will name it 'stuffy steel'." ”

Sarhan and Shuster were all focused on hearing this, and from what the master had said just now, Rollin was a knowledgeable person. Now it seemed that a more advanced blacksmith technique was going to be taught to them, and the two blacksmiths looked at Rollin expectantly.

Braised steel is a solid carburizing of block iron.

Rollin walked straight to the furnace where they were calcining.

Solid carburizing requires that the temperature should not be too high, and the requirement of modern steel stew is not to exceed 900 degrees, which is slightly lower than the 1000 degrees of block ironmaking, and the steel will not melt at this temperature.

With Targaryen's adaptation to the temperature and repeated verification in the laboratory, Rollin constantly adds charcoal to adjust the temperature to the right place.

"Remember this temperature, this is the right temperature for the 'braised steel' method." Rollin recounted.

Both Sarhan and Shuster used special iron rods to poke into the furnace, and they relied on the color of the tip of the iron rod to determine the temperature.

"The following is the most important process of stuffy steel, carburizing!" Rollin said in a deep voice.

Spread the toner, beef bone meal and sawdust to the bottom of the crucible in a certain proportion, and then put in the iron sword ready for carburizing.

Luo Lin directed the two to operate, making toner and polishing beef bones...... Finish in a container.

Theodore, on the other hand, was in charge of recording the steps of the 'stuffy steel'.

Put a layer of toner, beef bone meal and sawdust, and then put a layer of iron sword, and then stack them on top of each other.

Beef bone meal is a catalyst for carburizing, and sometimes it can seep into the iron and become an impurity.

Later generations have already figured out the proportions of various carburizing, and every 100 catties of pig iron needs 4 catties of toner, 20 catties of beef bone meal and 5 catties of sawdust, and Luo Lin directly used them.

"The bottom and upper layers should be placed a little more, and the middle layers should be placed evenly."

Rollin continued to command.

Under the command of Rollin, two blacksmiths placed layers of carburizing agent and iron swords into it, covered the crucible with a lid, and then sealed it with clay.

This is the stewed steel, and of course there is another container with sword embryos, which are much larger than iron swords, and are weapons ready for refining.

Two slave craftsmen put the two mud-sealed vessels into the stove and lit them.

Looking at Theodore attentively, Rollin was about to leave here.

It takes hours to stew steel, and it's boring to stay here all the time.

Telling Theodore to keep a record, Rollin left.

When it was time for Rollin and the family to dine at noon, Theodore ran over excitedly.

"Your Excellency, it worked! We did it!! ”

Theodore said excitedly when he saw Rollin, and then handed Rollin a half-handed sword.

"This is the half-handed sword you forged."

Luo Lin said as he looked at the somewhat pitch-black dagger.

"That's right, we used this half-handed sword to slash at the previous iron sword, and it was only after cutting off two iron swords that it made a gap. In the end, a total of five iron swords were cut off, and this steel sword was broken, which is a record of slashing. ”

Theodore said, holding a piece of parchment.

Theodore's eyes on Rollin were simply like the god of fire in the world, and the admiration in his heart was simply indescribable.

Steel swords were also available in Westeros, but they were expensive to make, requiring not only high raw materials, but also a week of hard work by skilled blacksmiths to produce a finished product.

The effect of this simple steelmaking method is absolutely subversive.

"In the next few days, we must continue to experiment to make the best steel sword, and we must do a good job of blocking the technology, and we must not leak it."

Rollin said to him.

"Yes, sir."

Theodore replied excitedly.

This is what makes a lot of money, and the arms trade is a profiteering industry in any world and era.
