Perpetual motion pump.

The Purifiers, and the entire Invig Technology Center, are the most cutting-edge scientific research institutions, with research ranging from alchemy steam technology to demons, and it can be said that they have promoted the development of science and technology in the entire world in one fell swoop, and the first steam prototype in history was built here.

The concealment level of this institution is very high, and in order to ensure concealment, most of them act as mechanical institutes on the surface, and most of the technologies are pioneered by them, and then handed over to the mature industrial lines of the mechanical institutes on the ground for extended research.

Their symbol is the snake that bites its tail, which is said to symbolize "perpetual motion" and "infinity".

"The security level here is the highest, and the same security level as it is in Old Dunling, along with the Broken Dome and the Platinum Palace. ”

Kestrel still acts as a tour guide, but at the moment he is even more excited than Lorenzo.

As a high-ranking knight, he is not qualified to arrive at the Perpetual Motion Pump at will, this place is as mysterious as a myth, usually you can only see an ominous train of carriages with dazzling sparks stopping in front of you, and then a few white coats will drag out with weapons that can slay gods and dragons, give you a thick instruction manual that can be used as a brick, and then disappear...... Sometimes, they even asked the scholars of the Mechanical Academy to send weapons.

Now the kestrel feels so wonderful, just like the sword hero walked into the casting yard of the peerless sword, although he didn't see the screaming of the idol like that, but when he thought that the power to fight against demons was now studied from this mysterious place, there was a strange sense of pilgrimage.

Whether it's the Original Sin Armor, the Ranger Project, or the world-changing steam engine, they all originated here, the mysterious Perpetual Pump.

"May I take some souvenirs and go?"

Suddenly, a ghostly voice sounded, but it wasn't the kestrels, but Joey, who had been silent.

He was looking blankly at the experimental field on the side of the passage at the moment, and through the barrier glass, he could clearly see a group of scientific researchers experimenting with weapons.

They were wearing fireproof suits made of asbestos, and they stood far away, and then they seemed to activate something, and the mechanical arm in the middle of the experimental field pulled the trigger slightly, and the armor fire fired instantly.

The bright room was paved with a blood-red color for a moment, and the high temperature prompted the ammunition to be discharged instantly, but due to the high temperature, at this moment, the entire fire gun was also exploded, and the half-melted metal expanded outward in a fan shape, and then the central burning warhead penetrated several layers of experimental steel plates, and the remaining molten metal fragments were also nailed to it.

The alarm bell in the test site was loud, followed by a surge of cryogenic gases to cool down the boiling and burning steel plates.

Several researchers looked calm, standing next to the molten wreckage, recording the values in a serious manner.

"The Dragon's Breath Armor Firegun, because of its excessive power, is used to explode, and finally made into a one-time consumable, the purpose of the current experiment is to optimize the material and reduce the cost, after all, this weapon is really used to lose a handful, and there is no need to change the load. ”

Tesla said on the side that the ideas of these scientific researchers are so strange that instead of thinking about ensuring that they do not explode, it is better to make consumables. After saying that, Tesla also glanced at Joey.

"That thing is for the Original Sin Armor, you can't use it, so you might as well pick up some other souvenirs. ”

Tesla led a few people all the way through the long corridor, during which he passed several experimental sites one after another, and the explosion made the entire corridor tremble slightly.

Kestrel had a subtle expression, and he knew very well that if the Furnace Pillar was described as an upside-down tree, the Mechanic was located at the root of the tree, and the Perpetual Motion Pump was located at the trunk of the tree.

Eventually, Tesla led you to a large experimental site, which was completely covered in fine steel plates, and the whole field was circular in shape, and when you looked up, it looked like a huge deep well, all the way to the dome overhead.

On top of the dome, an array of lights illuminates the entire test site, like the sun rising into the sky.

Along the edge of the shaft wall are several large lifting platforms, and as the motors slowly lift and fall, there are huge gates on the edge of the shaft walls, from which steel rails extend across the deep shaft, on which are hung an unrecognizable machine, which passes over the heads of the people and submerges along the rails into the gate at the other end.

The gears and cables were unabashedly exposed, and from time to time there were flashes of electric light, and a faint steam overflowed, but they were soon sucked up by the exhaust fan, and different command broadcasts echoed, and everyone was like a small gear on the machine, biting with precision.

"Welcome to the Workshop. ”

Tesla smiled.

"We're going to have our next experiments here, but let's get ready in the meantime. ”

He picked up the communicator in his pocket, and he didn't know what he said, and soon the whole workshop was moving.

The machinery hidden behind the steel began to move slowly, the otherwise flat ground was slightly raised, and one metal platform after another rose in the middle of the field, and at the same time the lifting platform on the wall of the shaft also began to climb, and the heavy gates fell one by one, sealing all the exits, and even the gate when Lorenzo came in was tightly closed.

"What are you doing here?"

Lorenzo was not worried, but asked with some curiosity, it was like a cage, and they were locked in it heavily.

"Protective measures, this is the largest and most protective experimental field in the perpetual motion pump at the moment, after all, what we are going to experiment with next is very dangerous. ”

Tesla replied as countless tiny bumps protruded from the edge of the wall of the shaft, one Geiger counter after another, completely covering the perimeter, in an extremely clumsy way to increase susceptibility to erosion.

"So let's get the appetizers out first. ”

The cargo on the rails began to descend, and finally slowly fell to the center of the field, and as the frame of the package opened, Lorenzo could see the contents very clearly.

His hands clenched involuntarily, and his voice was a little cold.

"Are you trying to provoke me?"

"No, it's just science. ”

Tesla's voice was very calm, calm no, he didn't care about Lorenzo's thoughts at all, he walked over directly and showed Lorenzo his work in all directions.

It was an illegible corpse, flesh mixed with silvery metal, but hollowed out inside, and the metal spine was placed on the other side of the corpse, on which tiny twigs of iron twisted and grew.

"Mr. Holmes, I have a lot of questions I want to confirm from you before I participate in the experiment. ”

Tesla put on his gloves and twisted the metal spine with pliers, which were covered with strange lines, as if countless lines intertwined.

"This is what you call it...... What the hell is the Silver Bolt?"

Lorenzo looked at Ed's corpse, the spine that had been completely wrapped in holy silver, and it was obvious that there was something on it that didn't belong to the body.

"What do you mean?"

"I mean, do you really know what the gospel church has put in you?"

As he spoke, Tesla pulled out something with countless tiny nerve wires from another pile of parts.

"Look at this, how subtle...... Technology. ”

Under that high magnification, Lorenzo could clearly see the complex mechanical structure, which was far beyond the level of modern craftsmanship.

"It was completely destroyed by the molten holy silver, we can only study the precision of this thing is beyond the current human being, don't show an unbelievable look, your current position is the perpetual motion pump, the birthplace of the entire mechanical civilization, but even this our factory can't make such a thing, and even imitation can't do it. ”

Tesla put it back in its place, his eyes filled with admiration and bewilderment.

"Mr. Holmes, do you know what that means?"

"What?"

Lorenzo vaguely sensed what Tesla meant, but he just didn't know how to explain it, thinking carefully about his experience in the Order, a witcher would perform [divine baptism] after receiving training, and the silver bolt and the implantation of the secret blood were carried out at the same time, they said that only the vitality given to them by the secret blood could make the witcher survive the implantation operation.

Implantation of the Silver Bolt.

That's when Lorenzo realized that he had never seen the Silver Bolt with his own eyes, and he never knew what he had in his body.

"This is not a process that can be done with modern technology, can you explain to me what this thing is of use to you?"

Tesla asked solemnly, saying that this mechanical technology beyond Invig was enough to make the entire country rethink its attitude towards the evangelical church.

“...... The device that controls the witcher will melt itself when our secret blood awakening level exceeds the threshold, killing the demon hunter who has completely demonized. ”

"So this thing can test the purity of secret blood in your body on its own? That's amazing, we have a device to detect similar levels of erosion, but that thing is the size of a cart, and you have to stick a probing needle into your head. ”

Tesla's unstoppable praise continued to ask, in his eyes Lorenzo was a huge treasure waiting for him to excavate.

"What else?"

As if he was about to uncover a huge truth, Lorenzo actually felt a slight fear, not because of some simple death and demons, but just the fear of the unknown, like walking in that deep fog, you never know what will be behind that fog.

"The connection to the temple of stasis. ”

Perhaps it was the trust of his allies, or the pressure from Imam Lawrence, but Lorenzo did not hide it this time.

"You can understand it as something like a communicator, the 'communicator' within our witchers, and I don't know much more, after all, I can't return to the Stagnant Temple. ”

Tesla didn't seem surprised by anything, he continued.

"Hmm...... Is it possible to conduct ultra-long-range radio communications without the need for a base station? I began to celebrate that the Happy Sound Church had played itself to death, otherwise we might not have been able to fight the war. ”

Tesla explained with his own understanding of technology, and the way he looked at Lorenzo changed slightly, but it quickly changed.

"What exactly do you want to ask?"

Although Lorenzo had not taken a class on mechanics, he began to feel a lot of bad things about his increased experience in college.

"It's nothing, it's just a lot of ideas, so let's change the subject. ”

No one knows why, Tesla did not continue to go deeper on the topic of the silver bolt, but turned the finger elsewhere.

Without waiting for Lorenzo to continue to ask anything, the metal frame closed and pulled Ed's body back up to the rails, and then another heavy container fell, and the moment it hit the ground with a fierce wind, the mottled and rusty container burst open, eroding and engulfing everyone.

Lorenzo looked at the contents of the container, and the researchers around him walked over, wearing isolation suits, inserting the slides into it, and then the steel knight inside slowly walked out of the darkness.

It was an original sin armor, but unlike the original sin armor Lorenzo had seen, it was too large, bloated, the complex mechanical structure was not well protected, most of the steam engine was exposed, and many parts could be seen to be outdated, just like a weapon more than ten years ago.

"What you see now is the original Original Sin Armor, the first Original Sin Armor we built after receiving the technical support of Jiuxia, which we call 'New Hope'. ”

Tesla explained.

In the crucible of more than a decade ago, the demon that changed the war appeared.

"What do you want to do?"

The kestrel asked directly, he was very afraid of the original sin armor, and in his eyes this thing was extremely ominous, like a silent beast that would slowly devour the knight inside.

He still remembers the tragic situation of the shrike in the hospital.

"Quite simply, as test drivers, you must understand the basic composition of the original sin armor, and don't be like him, who doesn't even know what's in your body. ”

Tesla said and glanced at Lorenzo, full of sarcasm.

But then Joey asked again.

"Wait, you say, 'you'?"

The usual rigidity was gone, and Joey's expression began to grow in wonder.

"Yes, you guys, do you think the Perpetual Pump is where you can come whenever you want? ”

"No, wait a minute, our resistance to erosion is not that high, you are sending us to death!"

Kestrel screamed, loyal to the purifiers, but he lacked trust in these neurotics.

"So that's why we brought in Mr. Holmes, and he's going to be involved in the optimization of the second generation of armor until people like you who are not resistant to erosion can drive it. ”

Tesla...... To be precise, Merlin, he has made all the plans for this project, from the selection of candidates to the test drive armor, they are a bunch of unlucky guinea pigs, inexplicably into the cage.

The two of them were extremely out of shape, the ghost cried wolf, they looked at the heavily protected workshop, and were still thinking about whether they could fight all the way back to the surface, and Lorenzo seemed very calm, as if he had expected all this, he only looked up slightly, looking at the container on the rail.

The container that gradually disappeared behind the gate, Ed's corpse, the mysterious silver-bound bolt.

At this moment, he suddenly truly understood what Arthur said about ignorance, and all the things he did not understand were blamed on the ethereal gods, and he never thought why it could do so...... It's like mysterious demons, inexplicable demons, who blame all their weird evils on the knowledge of the Church.

An inexplicable cold welled up in Lorenzo's mind, and at that moment he felt as if he had touched something, as if he had glimpsed a corner of the forbidden truth.
