Rand asked the soldiers to carry the struck steel plate back to the city, and watched the steel plate the thickness of his little finger being pierced by the black arrow for several inches, and old Sopa was also amazed at the great power of the ballista.

"This bowstring should be specially made, such a huge force will not break. Old Sopa licked his lips, the penetration of this ballista is too strong, the steel plate can easily penetrate, if the target is replaced by a cavalry equipped with plate armor, the plate armor is like paper paste in front of this armor-piercing arrow.

In the past, people usually used blunt weapons, sledgehammers or large axes to break through plate armor defenses, but after seeing the power of the ballista, old Sopa finally realized that when the sharp weapon was sharp enough to break through the plate armor.

"This is an arrow specially made for enemies with extremely high defense, a single armor-piercing arrow, and the effect is as you can see, unexpectedly excellent. Rand didn't say much about how the armor-piercing arrows were made, "Last winter, there were barbarians with their thick skin attacking Cabintown, but it turned out that the ballista could penetrate their bodies as easily as they did through sacks. ”

"Amazing weapon!" said Old Sopa sincerely, "but the rate of fire is a little slow, and if the enemy attacks in large numbers, the effect of this thing may be minimal." ”

"This brings us to its next feature, bursting!"

Rand turned the arrow groove into a burst groove and ordered the soldier to replace it with a lighter normal arrow.

A neat row of arrows shimmered with a cold black light, and they were as sharp as cavalry ready to attack in the arrow slots.

The burst slot is divided into three launches, each of which is large enough to hold dozens of arrows, and when assembled, it can fire all the arrows in two seconds.

Old Sopa pulled the trigger.

So there was a rain of arrows outside the town.

Dozens of arrows shot up into the sky, with a sharp whistling sound, and there was no collision between them, this exquisite orbital shooting made old Sopa really have some admiration.

After a while, everyone at the head of the city cast their eyes down, and those arrows were inserted into the ground extremely deep in twos and threes, and the area covered by the blow reached more than ten square meters.

"This coverage, combined with a very convenient way to reload, and it also has a fast rate of fire. Rand said, "With ten ballistas, I dare to face a thousand enemies." ”

......

"Lord Lord, those magical machines in your territory really opened my eyes!" After returning to the castle, old Sopa was still extremely excited, and he almost couldn't wait to disassemble a fuel engine and take a look at the specific structure inside: "The fuel engine, the ballista, the flintlock pistol, and that ...... Each vehicle called a tractor is enough to shake the kingdom!"

"Do you know, if the great instructors of the old alchemy workshop know about this, they will definitely refuse and dare not believe it!" "For the first time in his life, Old Sopa felt that his world view had been seriously impacted, these magical machines and weapons, not to mention the knowledge in the Imperial City Workshop, had never even heard of them, but in this remote and remote air realm, they really appeared in front of him, and he even operated them himself!

This is almost the pinnacle glory of a craftsman!

"I said at the beginning, if you want to learn, I can teach you!" Rand stared into old Sopa's eyes, word for word, with great sincerity and seriousness.

Old Sopa could hear the meaning of Rand's words, it was an invitation to join the Empty Ferry and serve Rand.

Although old Sopa doesn't like the barren environment of the air ferry collar, if what Rand said is true, these machines are all made by his hands, then he wants to transform the air ferry collar into a bustling city, I believe it will not take too long, and most importantly, old Sopa is really interested in these machines.

The frenzied look almost overflowed from his eyes.

And Rand's sincerity old Sopa can see, this kind of confidential machinery he took himself to visit all over without reservation, there is no place to hide at all, this alone makes old Sopa moved, think about it, if you research this advanced machine yourself, will you let others visit and operate without reservation?

The result was negative.

Not only themselves, but also any alchemist or craftsman, they would not have done such a thing.

Thinking about it this way, Rand's image immediately became taller.

Although his workshop is in the Imperial City, this does not affect his work with Rand, working for the Duke of Winton in the Imperial City is no different from working with the Rand in the Empty Ferry Territory, and it is also working with the Capet family, and the Duke of Winton will not pay attention to such trivial matters.

But most importantly, what about your apprentices?

They have been working with their hearts for so many years, but they want to abandon them?

Perhaps sensing Old Sopa's problem, Rand smiled and said, "My territory is in the development stage, and there are many relevant talents, and your apprentices and employees in the Imperial City Workshop, as long as they are willing to accept my employment, I promise you that they will not be treated badly." ”

Old Sopa opened his mouth, and the last trace of worry vanished.

"Looks like I'm going to have to accept your invitation. Old Sopa laughed and said, "I really didn't expect you to have such skills and wisdom that are ahead of the mainland!"

"These are just some of the most basic things, and when you officially settle in the Empty Ferry Territory, I will make you see more magical, stronger, and more advanced......" Rand thought for a moment, and felt that he needed to add an adjective in front of this title: "Great machine!"

"But now is not the time, let's solve the most important problem first!" Rand seemed to remember something, and ordered the soldiers to move the rigid rocks in the wooden box to the factory.

"Tell me a little bit about it, these are my two wonderful employees, Andy and Oak!" Rand spread his hands, "Just rock, they will take care of the problem!"

Old Sopa's smile suddenly froze.

He rubbed his hands a little embarrassedly and asked tentatively, "Are these two also alchemists?"

"No, it's a guy who is more powerful than an alchemist!"

"Leave this to them, and we'll go meet another guest. Rand winked at Oak and motioned for him to leave with Andy first, "That craftsman from Lindong City has been waiting for us for a long time. ”

......

"The composition of this rigid rock is very strange," Andy said with his hand as he picked up the silver rock on the table, with a solemn look on his face, "My ability has diminished a lot on top of it. ”

Andy closed his eyes and slowly covered the upper layer of the rock with his palm.

As soon as the rock began to tremble slightly, then the whole began to crack, and the fine stone grains were scattered on the ground, and if you looked closely, you could see that the stone grains were mixed with some silvery substance.

"This is the iron in the rock, and it can be broken down again, but more slowly. Andy frowned: "There are very few impurities in the ore. ”

"A completely new ore that has a melting point more than 2,000 degrees higher than steel. Oak shrugged his shoulders, this temperature was difficult for him to reach before he evolved, but after a metamorphosis, his ability to control fire has greatly increased, and he is able to increase the temperature of the flame released from his body to more than six thousand degrees.

This is an extremely frightening statistic, which is warmer than the surface of the sun.

"Your Excellency once said that oxygen fuels combustion. Oak remembered what Rand had told him that this colorless and odorless gas could accelerate the burning of flames, thereby increasing the efficiency of work.

"What is oxygen?"

"It's a gas contained in the air we breathe, but the natural oxygen purity is relatively low, so the combustion effect is not strong," Oak thought for a moment, "Lord Lord, if you can make a purification device, you can solve this problem." ”

"Well, it's something I've never heard of before. Andy is no longer surprised by the new nouns Rand often utters, "The laboratory he promised me to build has not yet been completed. ”

"That requires more sophisticated instruments, Lord Lord, chemistry is the most rigorous, and there can be no mistakes, so the progress of construction may be slower. Oak thought for a moment, and picked up a large piece of silver material from the ground and placed it in the palm of his hand.

"Teng!"

The incandescent flames burned in his palm, and the silver substance melted at a speed visible to the naked eye, quickly turning into a mass of molten iron.

Although the temperature inside the flame was extremely high, Andy, who was not far away, did not feel any scorching at all, and Oak controlled the temperature of the flame in the flame body of the flame, without leaking any outward.

This kind of astonishing control is unmatched among all the demon species in the Empty Crossing Realm.

"Your proficiency in flames has risen again. Andy said softly.

It's just that it's not necessarily a good thing......

Oak felt a little heavy when he remembered what Shadow had told him about the connection between magic and the body.

Recently, the magic in the body has started to be restless again.

Every night he could hear the sound of the magic tide surging, as if it were rising.

Wave after wave slammed into Oak's body.

This is an omen.

Oak looked at the incandescent flames in his palms, a little distracted.

It's only been a long time since his last evolution, and the magic power in his body has actually swelled again.

This is a harbinger of the second evolution.

The pain of the last evolution is unforgettable for Oak, and the burning sensation that hurts into the bone marrow seems to linger, and everything feels like yesterday.

Oak's eyebrows throbbed violently.

He was not afraid of pain, but he was somewhat afraid of failure.

Failure means death.

He didn't want to die, he wanted to stay alive and stay in the empty realm.

So he was a little scared of this second evolution.
