Mobius really wanted Rosen's battery technology, from the west of the city to the dock, and from the dock back to the west of the city, back and forth, but in half an hour, he carried 3,000 gold dragon coins.

During this half hour, Rosen also wrote down the details of the battery on a piece of parchment.

In fact, his battery is a lead-acid battery, the structure is simple, the positive electrode is made of lead dioxide, the negative electrode is lead, and the electrolyte is sulfuric acid.

In order to take care of Morbius's reading method, Rosen deliberately changed the nouns in it, such as lead dioxide, and he wrote it as lead rust.

When Morbius handed over a large bag of heavy gold dragon coins to Lawson, only to exchange it for a piece of parchment, his whole body was in a mess.

"It's as simple as that?" Molius was a hundred unconvinced, he took the parchment and looked through it to find out more, but naturally he was disappointed.

Rosen smiled and asked, "Don't believe it?" ”

Morbius is about to go crazy, 3000 gold dragon coins, he has saved for nearly 10 years, so he changed this piece of paper, not to mention that he became a poor egg, and he also owed the other party 2000 gold dragon coins, how to think about how to be aggrieved.

If he wanted to change someone else, he would have done it earlier, but Rosen had Veronica by his side.

Taking a deep breath, he looked at Veronica with a sad face: "This kid is ...... He bullies! ”

Veronica also felt a little simple: "Lawson, isn't it too perfunctory?" It's 5,000 gold dragon coins. ”

With 5,000 gold dragon coins, you can buy a super mansion in Nilogaard.

Rosen smiled slightly, took a step back, walked to the battery, and then beckoned to Mobius: "Come on, come on, if you don't believe it, come and take a closer look inside this thunderbolt cage." ”

As he spoke, he opened the lid of the large wooden box.

Morbius looked over and found that the wooden box was also inlaid with a layer of transparent glass, and the glass was divided into many small compartments, which were stuffed with things, and when he looked closely, he looked back and compared the instructions on the parchment, and the two were exactly the same.

"If you do this, you can really tame thunder and lightning?" Mobius has a feeling of seeing a ghost, thunder and lightning are the weapons of the gods, and they can bind the cage of thunder and lightning, and they are very tall when they hear it, and the structure is so simple, it is really unbelievable.

"Do you want to believe it, and pinch these two pieces of iron again?"

Mobius really pinched it, and as soon as he pinched it, his whole body began to tremble, and that unique tingling feeling couldn't deceive people.

"Believe it, huh?"

"I believe it." Morbius nodded, but was still a little uneasy.

Seeing him like this, Lawson said earnestly: "Don't look at the few words on the parchment, but none of the words on it are nonsense. Do you think I got something on this scroll out of thin air? No! Let me tell you, behind every word, there is the hard work of several ancestors. In order to create this thunder and lightning cage, I don't know how many ancestors have worked hard and spent a lifetime! ”

"Huh?" Morbius really didn't expect this.

Rosen asked loudly: "I'll ask you, countless wise ancestors, a lifetime of time, is worth 5,000 gold dragon coins!" ”

"Value!"

"Then what are you still aggrieved about? Why don't you take this scroll back and build a thunderbolt cage as it says. It's done, whether you sell the electrolytic metal for money, or sell the lightning cage directly, isn't 5,000 gold dragon coins earned back in minutes? ”

These words woke up Morbius, and he slapped his head hard: "Rosen, you're right, thank you very much for reminding me!" ”

After speaking, Morbius didn't stop for a moment, put away the parchment, and ran away, as if he had grown a lot of money, as if he was afraid that Rosen would regret it.

"Stop!" Lawson suddenly shouted.

Morbius stopped by the door, held the scroll tightly in his arms, and looked at Rosen vigilantly: "What, do you want to regret it?" ”

Rosen shook his head, reached into his fanny bag, and pulled out a milky crystal, and two wires were pulled out from underneath it. Lawson connected the wires to the two poles of the battery, and the milky white crystal suddenly shone brightly.

"Soft Light Crystal?!" Morbius's eyes lit up, Adele's moon wand was rumored to be miraculous, especially the glowing soft crystal, which he had heard many times about.

Lawson put away the milky crystal and smiled, "The oil lamp in your warehouse is too dim. If you can pay off the remaining 2,000 gold dragon coins as soon as possible, I will give you this soft crystal. ”

Morbius was a spirit: "Seriously?!" ”

"Veronica is there, she testifies."

"Good!" Morbius shouted excitedly: "You wait for me!" ”

After saying that, he quickly turned around, ran directly from the door to the window, and then jumped out directly from the window, and then ran all the way away.

Veronica watched the whole process and waited for Morbius to shine, and she couldn't help but spread her hands: "How did Morbius become so good at talking?" How do I think he's a little stupid? ”

"He's not stupid, he's innocent, hehe."

Lawson carefully put away the gold dragon coin, then took the prepared aluminum powder and magnesium powder, and began to get busy again.

This busyness came in the middle of the night.

By this time, a total of more than 20 kilograms of aluminum powder and magnesium powder had turned into more than a dozen round dense cardboard packets.

Veronica was originally very curious to see how Lawson made a bright light, but after watching it for several hours, she didn't understand anything, and in the end she had to go to rest, leaving Lawson alone in the alchemy room.

At this time, it was already late at night, and everything was quiet, and there was not even the movement of insects outside the window.

Lawson put away the paper bag, walked to the window, and tightened the curtains, leaving not a single crack, and at the same time only a candle was left, and the huge alchemy room suddenly became very dim.

Lawson walked lightly to the wall of the alchemy room, crouched down, picked up a piece of magnetite, and began to take a closer look.

"Iron black, scaly, microstriped metallic luster, weak magnetism, it's ilmenite!"

For Rosen now, iron is not valuable, what is valuable is titanium, that is, the mythril of this world. According to Morbius, this thing is a key element in increasing the power of the undead.

Although, for an alchemist, no matter how strong his body is, he can be destroyed by various alchemy methods, but if he is an alchemist and has a strong body, it will be like a tiger with wings!

Gently break out a small grain of iron and titanium ore with your hand, put it in your mouth, and swallow it directly, while activating the alchemy power and carefully observing the situation of the ore in the stomach.

"The ilmenite has not moved or been absorbed, and it seems that the constitution of the undead cannot directly absorb the titanium oxide in the ilmenite. It's right to think about it, if I could absorb it directly, such a good thing would not be my turn, and it would have been eaten up by Mobius a long time ago. ”

It doesn't matter if it can't be absorbed, Lawson can extract the titanium in it and eat it.

This was not a problem for Lawson at all, and with the existing materials and tools in the alchemy room, it was enough to extract pure metal titanium.

Inevitably, there are many dreams in the night, and Lawson goes straight to work.

This night is destined to be a sleepless night.

Lawson sweated like rain, using pickling, crystallization, cautery, displacement and other chemical methods, and was busy all night, and finally succeeded in consuming 40 Nilo pounds of ilmenite at more than four o'clock in the morning. In the end, he got 7 kilograms of pure metallic titanium powder, which is more than ten times the amount of titanium in Viken's skull.

If Morbius knew that Rosen had so much Mithril in his hands, and that the raw materials were given out by him himself, he would vomit blood in anger.

After getting the titanium powder, Lawson used the titanium powder as white sugar and swallowed it one bite at a time.

As he devoured it, he activated the alchemy power again and carefully observed the internal changes in his body.

He found that his current body has an amazingly high absorption efficiency of pure metal titanium, and after eating a spoonful of titanium powder, it will be absorbed by the stomach and intestines in less than 5 seconds, turning into a large number of titanium ions, which are swimming around in the body.

As the titanium ions continued to absorb, Lawson also felt that his body was filled with a cold breath, which was similar to the first time he took the moonlight elixir, but there were slight differences, compared to that time, today's cold breath was much milder, making people feel a little comfortable.

Seven kilograms of titanium powder, it took Lawson half an hour before and after to eat it all.

After eating, the effect is very noticeable.

Rosen discovered that his skull, entire spine, ribs, shoulder blades, and hip bones had all been turned into hard bio-titanium alloys.

'Viken the vampire has lived for at least 100 years, and has only converted his skull into bio-titanium. Morbius is supposed to be about the same age as Viken. Veronica's ability to easily break his leg and shoulder bones shows that Morbius is not much better off than Viken. I'm in this situation now, I'm afraid that the bones of the Elder of the Blood Rose are not as hard as mine. ’

After that, Lawson tested his healing ability, nerve reaction speed, and physical strength separately.

This time, though, the test results weren't as perverted as he had imagined.

'The healing ability has only improved slightly, and it takes more than 15 seconds for superficial scars to heal. His physical strength has improved slightly, and he is much stronger than ordinary people, but he is far inferior to Veronica and a lot worse than Annie. The speed of nerve reactions, which has improved significantly, is visually faster than Annie, slightly worse than Veronica, but there is no crushing advantage. ’

His current physical combat power, although far inferior to those traditional undead, is even worse than Morbius. But the good thing is that he is not afraid of silver, he has no blood addiction, his physical protection ability, especially the protection of the nervous system, is super perverted, and at the same time, he is also an alchemist.

"A body with amazing defense, a lightning-like reaction, and a powerful alchemy equipment are enough!"

Lawson left the alchemy room satisfied.

Although he had been busy all night, he did not feel tired at all, but was in good spirits, and it was already five o'clock in the morning, and Lawson simply ran to the garden of the mansion to run and exercise.

When he did this, he startled the early servants in the mansion.

After running out of sweat, Lawson directly took a bucket of cold water to rinse his body, and then just in time for breakfast in the mansion.

At breakfast, little Alice looked at Rosen carefully, and suddenly said, "Brother, you seem to have become stronger." ”

Sister Mary also said: "It's getting stronger, and I've grown a little taller." ”

Veronica also felt that Rosen seemed to have changed, but after looking closely, except that her body had become taller and stronger, she couldn't say anything was wrong, so she could only say, "You seem to be in good spirits." ”

Lawson was secretly refreshed in his heart, and he didn't explain, just gulped down wheat porridge.

While eating, a servant hurriedly ran in and said a few words to the butler Ah Fu who was standing aside, and the butler Ah Fu's face changed slightly, and he came up again, and whispered in Rosen's ear: "Sir, there is a visitor from outside the door." A man and a woman, the female being Miss Hill, a trainee magician, and the man calling himself the mathematician Vicky. ”

"Mathematician, Vicky?" Rosen smiled playfully.

"Yes, this Mr. Vicky seems to be very emotional."

Rosen laughed and said, "Please let them come in and let them wait for me in my study." ”
