It's another sunny afternoon, you can be regarded as sending away the group of ruin residents, look at this and that, and dislike straw paper shoes, which are not good, it's good to keep warm, you can't afford the expensive ones, even I am reluctant to buy that Lingxiu tactical boots~ The demon dragged a quilt of Ke Rong grass, yawned, and came to the sunny balcony on the second floor of the shoe store, winter is coming, I don't know how long such a small day of taking a nap in the sun can last~

Well? What is that? As soon as the demon was lying on the chaise longue, his eyes were about to squint, when he saw a small black dot in the clear blue sky rapidly grow larger, and almost instantly, it slammed into a light blue transparent barrier in the air of Mochizuki Town, distorted its flight trajectory, and fell heavily on the rocky ground outside the town, and the sound of a violent explosion mixed with a scream that made people's hairs stand on end.

"Shelling! Fast forward to the underground base! The sound of demon blood immediately sounded over the loudspeaker above the town.

Cannon? Not good, those tactical boots on the counter! The demon shook instantly, got up from the recliner, and immediately ran towards the house, and just pushed the door open, he bumped into Aisu, who rushed over, and grabbed her, "Hurry up!" ”

"Don't, shoes~" Sure enough, as Ai Su expected, the little money fan wanted money and didn't want to die, the demon was hugged by Ai Su, and then pinched the soft flesh on the waist of the wealth fan a few times, "Come to help, don't worry about those shoes, go first!" ”

Before the words fell, there was a continuous explosion of shells outside, and the first cannon just now was a test shot, and this was the official shelling.

"Don't~ let me down~ grab a pair for me to wear~" Ai Su and a little sister who came over to hold hands hugged their heads and legs, and ran towards the entrance of the underground base with the demon drag.

"Let's go, little one~"

"Ma Ma's Tree House, Synny's New Home......"

"Leave that alone, little one!" The snake girl is worthy of being a creature with six hands, Maggie picked up the little Lori with one hand, and held the basket in the other, in the basket was a white kitten and two wolf cubs, and the rest of the hand carried some valuable bits and pieces by the way, twisting and twisting on the road and running fast, the big white wolf followed her.

As the sound of cannonballs continued to explode, the light blue shield in the sky continued to fade, and finally turned into nothingness, and in a small simple mage tower near the sea in Mochizuki Town, Hao Xiale turned pale and fainted to the ground.

A couple of little sisters rushed in from outside the tower, "I knew it! Quick, help the handle, carry the master, let's go back", the demon eye was originally in the main control room of the underground base, after announcing the artillery alarm, she suddenly remembered what Lin Ze had said about spiritual power before, especially the defense of missiles and shells, which consumed a lot of spiritual power, this shelling came too quickly, and the number was huge, and the speed was extremely fast, there was no warning at all, she immediately thought of Hao Xiale, and hurriedly led people to run up along the seaside path to have a look......

Hmph, no matter who you are, there is only one way to die if you go against our law court! Camberti sat in front of the monitor that received the picture from the satellite radar detection, and excitedly looked at the image of Mochizuki Town that came, the ruins, haha, all blown up into ruins, what if it can defend against missiles, that shield can't be consumed, boom! Give me a hard bang! Compared with the price of ballistic missiles, artillery shells can be regarded as nothing, and the newly transported magnetic rail heavy artillery from the headquarters is really powerful, and it can attack the base camp of those visitors from other worlds hundreds of kilometers away, haha, plus the use of large orbital calculation terminals and aerial satellite scanning coordinate positioning, you don't need to enter the defense circle of those guys, you can attack as you want, haha, now it's up to you what you do, um, wait, he quickly picked up the communicator, "What about the cannon, why did it stop?" ”

"Director, you've run out of ammunition."

"What? Isn't that a magnetic rail catapult launch, as long as it can be stuffed in, all the shells can be hit, you told me that it was gone? "Camberti naturally has a detailed understanding of the firing principle of the magnetic rail heavy gun, there is a slider in the barrel to eject the tray, the shell is loaded on the tray, and after the energy is turned on, under the action of the electromagnetic principle, the slider obtains the power along the magnetic rail outward, and at the same time gives the initial velocity of the shell above.

"Director, you can use a small-caliber shell to launch it, but the flight trajectory is not easy to control, and it is not accurate, especially if the distance is so far, should we use it?" Several operators said cautiously.

"Damn, order those ammunition factories, according to this caliber, whether it is modified or rebuilt, to replenish my ammunition as soon as possible, and also, take back the railgun and see!" After calming down and thinking about it carefully, Camberti understood that the small caliber of the projectile will cause additional wear and tear to the inner wall of the lower side of the barrel, which is not only a problem of inaccurate hitting, but also greatly shortens the service life of the barrel.

……

"I think this heterolayer fiber technology is of great value", in the sky, Lin Ze, who had become a giant eagle, discussed with Leia while flying, after so many days, he went around a city ruins and its surroundings, most of those goods were sold, especially the cheapest warm shoes and warm clothes, which were sold out early, and the consumption level in the city ruins was much higher than that of the small strongholds outside, but unfortunately there was nothing to discover.

"You mean...... Braided? Leia thought for a moment and asked.

"That's right, it's weaving vines", Leia really knew what she meant, especially after seeing the warmth principle of the miscellaneous fibers, Lin Ze continued, "We can try to cultivate some fourth-order weaving vines and make shoes alone, so as to avoid the problem of shoes not being durable", Lin Ze is of course referring to the main big lord, a certain female elf always likes to use her fists or feet, and an ordinary set of transformation weaving vine clothes can't stand such a toss at all.

Braided vines, a special Eteko that can remember the growth form when they are mature, were previously used by Leia to make a set of clothes and pants and shoes that were worn when they were transformed and restored, but because they were only ordinary third-order braided vines used at that time, they were extremely unstrong.

Leia thought about it carefully, if she can cultivate a kind of tough and wear-resistant vine on the outer surface of the skin, she can use this tough and wear-resistant tissue structure as the sole and upper surface, use the cell membrane layer as a waterproof and breathable permeable membrane, and add an organizational structure similar to miscellaneous fibers as a warm and breathable layer.

"It's a great idea indeed~ Wait, what's going on down there?" As soon as Leia finished answering, she saw the devastated Mochizuki Town at a glance.

"Mama...... Woo, the home is gone~" Little Lori saw Leia flying down from the sky at a glance, ran over crying, and threw herself into her arms, "I didn't take a lot of toys from Synny~Woo~"

"It's not good, the plush bear that this woman finally got in exchange~" Lexi seemed to be infected by the little Lori, and ran towards the tree house that was blown up and burned down by the shell, but unfortunately someone was faster than her, "Let go of me, stinky and shameless, this woman is not your hug bear, this woman is in a hurry~"

"My shoes~ I should have grabbed a pair to put on, even if it was damaged by the explosion, how good~" The shoe store was concentrated by two shells, and the entire second-story treehouse turned into a pile of crooked, collapsed and blackened wreckage on the ground.

"What's the situation?" Lin Ze saw the demon blood coming over and asked out loud.

"Shelling, and the distance is far beyond the range of defense and reconnaissance on our periphery, thanks to Master Hao Shaler opening the shield in time, we have time to retreat to a safe underground base, but unfortunately Master He is still in a coma, hey~" Demon Blood felt an inexpressible emotion entangled, both lucky, mixed with a little regret, and a little distressed.

"Cannon? Cannon? Bazooka? It's impossible for a cannon to hit so far? Lin Ze was stunned, shelling? The outer defensive ring is extremely far away from Mochizuki Town, how can the artillery hit here?

"It's not rocket artillery, it's just an ordinary shell, our Sisterhood doesn't know, we can only be sure that it must be an artillery attack from outside the outer defensive circle", from the ground to the air, there is not a trace of news from the stronghold of the Sisterhood, and it is impossible for a large offensive weapon like a cannon to evade the reconnaissance of the defensive circle.

According to this idea, the range of the cannonball is actually the problem of the initial velocity of the projectile, so if you want to provide such a large muzzle kinetic energy, the traditional chemical energy artillery will definitely not be able to do it, so if you calculate it, the law institute may use the electromagnetic principle of the artillery this time, yes, the underground base of the law institute in the south garden of the law has an electromagnetic Gauss rifle, and it is natural to use it as a cannon, I just don't know~

"Is there a blue light on the shell?" Lin Ze asked in detail.

"No, definitely not, do you suspect it......" Demon Blood was stunned for a moment, the blue light of the bullet is a phenomenon that the electromagnetic prototype gun made by Lin Ze has, he asked, could it be?

"If there is no blue light, it is very likely to be an electromagnetic cannon based on the principle of magnetic rail", the principle of magnetic rail is that the kinetic energy of the electric energy is converted into the kinetic energy of the energized slider, and the kinetic energy of the slider is transmitted to the cannonball on the pallet, and then fired, because the cannonball itself does not need to be electrified, and naturally it will not produce blue electric light due to friction discharge with air during flight.

"Magnetic tracks? By the way, the Law Academy does have a railgun, which is the main gun of the rail-tracked tank, and the rail-mounted tank can't hit this far, right? ”

"Of course, it's not the kind of portable simple railgun on the tank, but the principle is the same, the caliber is larger, the barrel is longer, the range is longer, and the law institute is really rich", the principle of magnetic rails has many restrictions on the application alone, the most troublesome is the problem of barrel ablation, the slider moves quickly after being energized, and the inner wall of the barrel produces contact friction, the faster the speed, the greater the friction, the greater the damage to the barrel, if there is no responsive anti-friction technology, the loss of the barrel will become a terrible burden.

"Master Lin Ze, can you produce this kind of cannon?" Since the Law Academy can use the main gun technology of the tank to produce the responding magnetic rail cannon, Lin Ze can also produce the corresponding electromagnetic cannon if he can also produce the corresponding electromagnetic cannon, and the demon blood brain is moving very fast.

"The principle of the prototype gun is okay", Lin Ze immediately thought of the fourth-order electric shock tree collected in the yard of the plant gene center before, and the electric shock tree in Lan Li's advanced laboratory was used to make the prototype gun before, or the short-aged electric shock tree that was spawned, as for the fourth-order electric shock tree in the courtyard outside the research center, it was still in the state of It's a special sub, "Let's study the countermeasures first~"

……

The bombardment came suddenly, and the end was also very sudden, the surface of Mochizuki Town was in a mess, all the buildings were not spared, the repaired gardens and canals were also blown to pieces, and after a hurry to clean up, everyone tacitly retreated to the area of the underground laboratory, and did not rebuild their homes, and the atmosphere in the conference room was silent.

"This shell is far more difficult to defend against than ballistic missiles, because of the large number and speed, if they choose to attack my mage tower, they will also not be able to defend against it", Shaniye's face was gloomy, especially when she encountered this weapon that could easily break through the defense of the mage tower, she was very worried in her heart, now it seems that the survival pressure of this world is far more terrible than that of the Yunshan world, this kind of random cannon beating, what city wall, what castle, all are the lives of ruins, and it is also a super long distance, she can only be beaten and cannot fight back.

"Oh, damn it, it's so annoying~ I can't take it apart and study it with my own hands with this weapon~" Fao's brain circuit is obviously a little shorter.

"Shut up, idiot!" Shaniye angrily tapped the table top of the conference table with her staff, yelling at Fa'o, and then she turned her head, "What about the teleportation array, that one is very important!" ”

"It's a little affected, it's no big deal, I've fixed it", Huofa rarely appeared in Mochizuki Town, and the news of the bombardment of Mochizuki Town, the Sisterhood, was hyped by the Law Academy, which was also a means for the Law Yuan to publicize its own strength and deter Xiaoxiao, "I have news that there are not enough shells of this caliber in the Law Academy, and their factory is seizing the time to produce and renovate." ”

"The location of the main body of the cannon cannot be found by our sisterhood, and according to the direction of the cannonballs, this artillery position is very likely to be in the depths of the sphere of influence of the Law Academy, and it is heavily defended", the demon was a little deflated.

"You have to find this position first, but there are too many strongholds in the law academy on this line, and it is unrealistic to check them one by one", according to the direction in which the shells fell, it was extended in reverse, and the demon eye drew a straight line on the map, and every point in the line could be an artillery position, and there are still many calculations to be made where.

"Probably in this area", Hao Xiale's face was still pale, his mental strength was excessively depleted, but he still came to the conference room strongly, he was the controller of the shield at that time, and naturally knew the direction, speed and inclination of the cannonball falling, he picked up the pen and drew a small circle in a straight line, "If the estimate is correct." ”

"What if you find it, kill it?" The Great Lord stroked his chin, obviously going further and further in the idea of killing in, simulating all kinds of small routines in his mind.

"It's not a good idea, we've attacked the main base of the Law Academy's West Garden, and we've also attacked their other strongholds, the Law Academy is not stupid, they will definitely take precautions against us turning into small animals, it's dangerous to act rashly", Leia was not carried away by the previous success.

"That's simple, Master Lin Ze makes a cannon, let's just shoot it back~" The demon suddenly interjected on the side, she had been angry that she couldn't grab a pair of free tactical boots before the shoe store was bombed, although she was reluctantly pulled to the meeting, she habitually deserted in her mind, and she opened her mouth to come without thinking.

"It's not that simple, the law institute has satellite observation and terminal calculations, as well as artillery data, which is the premise of accurate strikes, and we don't have the conditions to attack remotely and accurately after creating artillery", Lin Ze thought about it, and still told the actual situation.

"I have an idea," said Léa......
