Carmel departed, and Gawain sat quietly behind his desk, lost in a long contemplation.

He pondered the nature of magic, guessed the source of magic, and thought about how to block the interference of natural magic from observing experiments, and in contemplation, Amber, who was standing beside him, spoke: "You seem to have been studying the nature of magic...... Is this really a serious issue? ”

"Aren't you curious?" Gawain glanced back at Amber, and he saw that the half-elf's face was full of confusion, "Haven't you ever wondered what magic in nature is, and where it comes from?" ”

“…… Magic is magic, something as natural as air, it's a part of the world," Amber scratched her hair, "It needs to cast spells, it needs to prepare potions, and even some plants and animals need it to survive...... I think it's been around since the birth of this world, just like a stone. ”

"But the stone doesn't suddenly turn into a chaotic tide of magic, magic can, and it doesn't have to last forever unless we can prove that it's truly endless," Gawain shook his head slightly, "What if magic is just a fleeting miracle?" Of course, this 'transience' is relative to the years of the whole world, but perhaps magic is just a small phenomenon in the long cycle of this world, just like a moment of calm in the waves of thunder, we mortals are born in this moment of calm, and the life is even shorter, we are born in peace, we think that the essence of this world is a calm water, but we don't know that the next second will usher in a storm, or magic is something with limited reserves, it is consumed every moment, but before it is exhausted, Mortals have no way of detecting and measuring ......"

The more Amber listened, the more surprised she became, and finally her eyes widened: "How did you come up with these sensational ideas!" ”

Then she looked Gawain up and down with a strange expression: "No wonder you often look mysterious...... It turns out that your mind is full of this strange thing every day...... In other words, you must have seen something in the 700 years that your soul was out of the body, right? ”

“…… It has nothing to do with that," Gawain shook his head with a smile, "Forget it, one day you'll be ......"

He wanted to say, "Someday you'll understand this," but then he thought about Amber's laziness and poor thinking in the field of knowledge, and finally his tone changed: "Don't think about it so much." ”

Amber thought for a moment and narrowed her eyes, "I think you're belittling my intellect......"

Gawain didn't pay attention to the half-elf's small protest, he just stood up, left the study, and came to the magic laboratory near the study.

This lab belongs to Hetty, but since Gawain also has some knowledge in the field of magic, there are some things that belong to him here. He went to a corner of the lab, took a set of devices from the cabinet that had been sitting on hold for a while, and brought them to a nearby bench to assemble them.

Its structure is simple, a light shield with small holes, a baffle with narrow double slits, and a flat light screen - the precision of this device is unmatched in this era, thanks to the finishing power of the Nicholas egg.

The baffle of this device is not a magic suppression crystal, but an ordinary opaque metal plate, so it is not used to observe the double-slit interference of magical power, but an ordinary device for observing the double-slit interference phenomenon of light, it has been placed here for several months, and the relevant observations have long been recorded, but today, Gawain wants to see it again.

He set up the monochromatic light source in front of the device, extinguished the lights in the lab, and began to carefully adjust the relative position of the baffle and the light screen.

No matter how you adjust it, what appears on the light screen is always a chaotic, diffused halo.

The halo fluctuated as Gawain adjusted, like the devil's malicious smile, taunting the powerless tester.

There are no interference streaks.

Gawain seemed to be back months ago, feeling the shock and confusion he had once again felt when he first observed the halo through the device.

The light of this world does not seem to be light, yet the simple optical devices he designed such as telescopes are in normal use.

There are no interference streaks on the light screen, which may be that the accuracy or adjustment range of the device is still not enough, or it may be that the "light" of this world really has no fluctuations, but after combining the conversation between Kamal and himself today, combined with the same problems that the elves encountered when verifying the fluctuations of magic power, he has a new guess: perhaps, this device is also interfered with by the magic in nature.

Is the "light" of this world also a kind of magic? Is it a visible magic that can be obscured by ordinary opaque substances? Or is it possible that the magic of this world can affect the fluctuations of light in the microscopic realm, so that all double-slit interference experiments will fail if exposed to magic?

Looking at the hazy and chaotic halo on the light screen, Gawain fell into a long thought.

……

It's autumn.

As the most striking constellation in the summer night sky, the constellation Drift Fire gradually moved away from the highest point of the sky and became a regular visitor in the western sky, while the "Frost Constellation", which represents the waning heat of the summer, gradually rose and began to move towards the center of the sky.

January is the cold month every year, February is the month of recovery, March is the month of fire, April is the month of harvest - the rise of the Frost constellation means that the hottest time of the year is coming to an end, representing the harvest of autumn has come to the earth, it will continue to rise in the following frost and fog moons, and every day closer to the highest point of the sky, and in order to distinguish the change of solar terms, the Ansu people gave the Frost constellation a name for this season when the Frost constellation has just begun to rise, called "April Frost".

The name had briefly puzzled Gawain, and although he knew from his memory that the word "frost" in this phrase did not mean to welcome frost and snow, but to welcome "frost constellation", the inertia of the earthling's thinking made it take him a long time to associate this "cool" name with this day that still had a slight residual heat feeling.

He's finally adapting to the world.

In the government hall, the weekly report meeting was underway, and Gawain sat at the head of the long table, listening to the report of the Minister of Agriculture, Norris, with a calm face.

The minister, who was already showing signs of old age and was a poor farmer, held the information in his hand, and although he tried to stand up straight: his upper body was still a little rickety: "...... Crops are growing well in the newly reclaimed areas of Hossman, Kant, Carroll, Gülen, and Tanzania, and the harvest is expected, while the new lands in Peibo, Constine, the western wilderness, and the northwest are not yet completed due to the late reclamation, land consolidation and replacement, and the problem of population relocation, so it is possible to complete the grain production plan......

"The roll-out of new agricultural machinery in the Horsmann and Kant regions has been very good, and some of the early crops have been harvested ahead of schedule......

"Testing the 'Harvest-II' Druid agent in the North Shore test field has been a phased success, and the next step is planned to be to assess the subsequent impact of the new agent on the land...... Ahem, ahem, ahem......"

Gawain looked at the Minister of Agriculture: "Norris, are you okay?" ”

"Ahem, I'm sick, I've been coughing since autumn," Norris waved his hand, "That's all for my report, and I've given the details to Ms. Hetty." ”

Pittman, who was sitting next to him, winked at Norris, "Hey, do you want to try my medicine?" I'll tell you, your problem is not a problem with me......"

"Pay attention to order during work," Gawain glared at Pittman, then glanced at everyone on the scene, and exhaled slightly, "Then today's meeting is here, adjournment." ”

Soon, the people in the conference hall dispersed, and only Gawain and Herty were left in the large room—and an invisible cat beside Gawain, snorting amber for an hour.

"Ancestor, the messenger from the royal capital has arrived at the Rock Fortress," said Hetty, "led by Cohen Loren, deputy head of the Royal Knights, and, according to the messenger, the first supplies for the construction of the barrier have been loaded into the port of the upper reaches of the Dolgon, and if nothing happens, they will arrive south within twenty days." ”

The elves sent the letter as the advance messenger, the official envoy of the royal capital arrived, and at the same time, supplies from the northern regions were loaded onto cargo ships in the upper reaches of the Dolgon River, so that the interlocking actions showed one thing: the opinions of the royal nobles were finally united.

Victoria Wilder...... The ability of the northern grand duke is still very reliable.

"Their efficiency is finally getting up," Gawain nodded, "How has the Pathfinder engineering team been doing lately?" ”

"The Pathfinder has set up a forward base on the northern border of the Black Forest and has begun to advance deeper into the forest, and there have been several brief engagements between the escort and the monsters in the forest, with only one soldier slightly injured and no other casualties."

"Crossing the Dark Mountains means crossing the border of civilization in a safe zone, so be extra careful to guard against the enemies in the Black Forest," Gawain said slowly, "You can go with me to the South Gate Fort and see how the construction is going there." ”

Hetty lowered her head: "Yes." ”

Gao Wen snorted and took the melon seeds on the table next to him: "Don't eat it, come with me." ”

"Oops!!"

……

The southern foothills of the Dark Mountains, the South Gate Fortress.

Strictly speaking, this is not the "South Gate Fortress", but only a huge semi-finished fortification and a busy construction site.

Construction machinery, construction materials, and engineers from Cecil City were stationed in the former "Shadow Laboratory", and a large and sturdy reinforced concrete fortress was built on the basis of this huge cavern.

Under the command of Gordon, the construction director, the engineering team has strengthened the southern wall of the cave with permanent cement fortifications, built a steel mechanical gate and several fire and observation points on the mountain wall, and inside the cave, the powerful large magic crystal lamp makes the entire cave as bright as day, the original remnants of Gondor in the cave have been sorted and recovered or cleaned up, several pools of water and potholes have been filled in, new magic net base and ground have been paved, and the original exposed stone wall has been reinforced. The construction of walls and pipes began.

The engineering team was now setting up support columns in the south and west of the cave in preparation for the construction of the second floor of the fort, while Gordon himself was in the center of the cave, supervising the protective isolation and repair of the "Shadow Gate".

The portal to the Shadow Realm has been damaged, but Miss Amber is still able to use her unique powers to enter the depths of the Shadow Realm through the gate, and the lord believes that this portal has special scientific significance, and since the portal itself is a fixed facility on the surface and cannot be moved, Gordon intends to protect it and turn it into a special facility within the fortress.

A mechanical bachelor wearing a yellow overalls equipped with a magic guide terminal came to Gordon and saluted the Ministry of Construction: "Mr. Gordon, the materials from Cecil City have arrived—they are sent to the forward base, do you want to personally accept them?" ”

Gordon looked up and saw several trucks parked under the lights, with Cecil's Ministry of Construction logo hanging from them.

He nodded, and strode over to the truck, "I'll take a look." ”

The supplies sent to the forward base are important items, and there is no room for sloppiness.

Thanks to the new technology of the Magic Car, which was capable of transporting the equivalent of a small wagon convoy at once, and thanks to the advanced construction skills of the Gondor Empire, the main corridor of the Fort of Disobedience allowed such large vehicles to pass through it at will. Gordon made his way to the back of the truck, climbed the ladder, and began to inspect the truckload.

Food, clothing, new water purification units......

Gordon nodded, ticking the boxes in the "Subsistence Provisions" section of the record sheet in his hand.

Then he came to another truck, and the supplies of this truck came into his sight—

Crates of Rebecca Crystals, individually wrapped Detonating Runes, Druid Blight Flasks, Type II High Explosive Bombs, and matching fuses......

Gordon nodded again and began to tick the "Construction Consumables" section of the record sheet.

While ticking, the building minister couldn't help but mutter: "How the hell do these things count into the construction consumables......"

(My wife has been in labor these days, and I have to accompany me in the hospital throughout the whole process, and I will try to maintain the update recently, but in case the manuscript can't stand the interruption...... I hope you can understand =. =

Ladies and gentlemen, this is really coming soon!! ）
