Even if you don't know what kind of powder it is, no one will bother to assemble it. The sappers carefully moved the open barrels out of the house - and carefully covered them with umbrellas to avoid exposure to the sun.

"Who knows if this thing will explode if it's sunburned?" The former engineer company commander explained.

The chronograph spring, which is apparently the detonation delay mechanism, and the springs, which are used as mine desensitization devices, are also packed in small plastic bags. As for the small wooden stick next to the whole box, it is obviously part of the whole set, but considering that there is only a fine layer of dirt on it, the opened box is sealed and sent back.

Large and small wooden cans are also loaded onto flatbed carts and waiting to be transferred...... Elta's satellite communication network is not very complete for the time being, otherwise these sappers would not have to spend this Rausch - they can get a rough answer by taking pictures and sending them to the rear.

The communication with the superiors soon ended - the sappers were asked to move these terrible unknown products to a place that "could be safely controlled, and would not be affected in the main camp area in the event of a martyrdom", and the rear would immediately send experts who were proficient in this field by helicopter to study on the spot.

However, the person on the other side of the phone also revealed: according to their description, eighty percent can be sure that the powder in the jar is magic powder. However, they are still asked to be cautious, the blast suit on their bodies will not be able to stop a few kilograms of equivalent explosives - let alone such a large barrel.

"Miss Fire? Yafizlna? A hurried voice echoed in the hallway of Mendong No. 1 Middle School. The person who came drove the car directly into the front hall of the car face, and the car door was too late to close, so he rushed to the campus and shouted people.

"Huh? Who's coming? Someone on the third floor suddenly answered. What's going on? I'm in class! ”

"Let's, let Yafizerna come down, there's a mission! Something to do with explosives! I'm Don ...... from the General Staff"

"Okay, okay, your leader called me and told me."

In this way, Yafizerna got into the car that went to the helipad in Mendong City. The staff officer didn't say a word along the way, in fact, because his Elta language was not good, and he only reached the level of saying hello or not saying thank you and sorry every day.

Yafizerna wanted to ask about the details of the "explosives", but the officer replied "I don't know, I'm sorry" in broken Elta, so she didn't ask any more.

The details of the explosives were not known to this staff officer. Not only did he not know, but the accompanying officer waiting for her by the helicopter also shook his head helplessly. In terms of other knowledge, they can easily overwhelm the members of the Red Dragons, but the magic and the deeper secrets of this world can only be learned little by little from the natives.

"This is undoubtedly a magic fan." As soon as she got off the plane, she went straight to the temporary warehouse, which was being guarded by layers. "The condition is very good." She grabbed a handful of magic powders and let them float back into the bucket.

"Any clue?" The accompanying staff officer hurriedly asked.

Jafizerna fiddled with the lid with the holes and round grooves, then pointed to the holes and said, "There must be something like a stick or a stick around here, please find it—but I probably understand what it is." ”

The box that had just been closed was opened. The bundles contained severed sealing wands. It's just the kind of lowest, the worst quality, that can only be used once.

Jafizerna drew her wand, a blue glow covering a short wand that had been drawn out.

"There's nothing wrong with exploding magic." Yafizerna had a blank look on her face. "I've had ideas similar to this design, but the Church of the Two Moons has gone further here."

Somewhat excited, she began to explain the principles of these weapons to the sappers and staff officers in front of her.

"The magic wand with the enclosed spell will cause an explosion as soon as it touches the magic powder, and the intensity of the explosion magic varies depending on the skill level...... Well, this technique should be on par with mine. ”

Speaking of this, Yafizlna's body shook. The drawings and materials that were abandoned on the ship may have been a guide to this kind of magic, or the principles of this kind of weapon.

"It's comparable, and then what?" The engineer commander was in some urgency.

"Judging by the mounting position and the roof plate above, this spring should be used to be buried in the ground. If you don't install a spring, then the paving will directly press the wand into the blast canister, killing your own people. With the addition of springs, it may be able to bear the weight of the covering soil. ”

Yafizerna did not know that there was a second use of this type of bullet - that is, to do the opposite, to tie the barrel tightly with a rope, to control it by man, and to pull it hard when an enemy approached, which was equivalent to a thunderbolt in nature.

"Mines?!" There was some sensation among the staff officers and sappers. An arquebus, or even a troop that doesn't have a three-eyed gun, actually made a mine, and this tech tree is not only a little jumpy, but also very crooked! Can they really use it - that's the idea of the staff officer.

The sappers began to have a headache in the shadow of the mines. Luckily, the huge bronze spring can be used with a metal detector, otherwise you would have been blinded.

And the other type, with a timed clockwork, is obviously a "grenade". It weighed as much as a small thermos, but it was very heavy—Yafizerna estimated that its actual use was to drop it from the city walls. If you throw a parabola, you will usually blow the thrower to pieces.

As for power? Jafizerna gave a clear reply: "It is indeed possible for a dozen of these canisters to blow up a small building with wooden frames and brick walls. ”

The veteran engineer who took the lead asked the staff officer a question in a bit of a hurry, and the staff interpreter conveyed it: "Is there any way to detect the existence or neutralize it?" ”

Hearing this, Yafizerna smiled, "The default wand for this type of weapon has a limited time. As long as a period of time passes, its usefulness will be lost - the chest containing the wand of the preset spell itself has the power of imprisoning magic, but when activated, it has no effect. ”

When the old sapper heard such a reply, he shook his head helplessly. Now that the rest of the troops are moving at full speed, we can't let the lead car or the vanguard slow down and make a metal detector beep on the road, right? Not only will it reduce the speed of the march, but it will also be unrealistic at all.

The same is true of mine obstacles in modern warfare. Even if the sea power wants to enter the Persian Gulf, the Bohai Sea, the Suez Canal and other areas blocked by mines, and can guarantee 100% detection and 100% removal of mines, the time to dig a pit and bury mines, or to drop them on a fishing boat with mine insurance is undoubtedly much shorter than the time to make them harmless. You must know that these quick and slow victories are undoubtedly victories -- but in the time of delay, the enemy can divert more forces and prepare for more defeat...... This is clearly disadvantageous for the attacking side.

This is also the means of exchanging space for time. Compared to the magic guns with limited rate of fire and power, the magic powder mines are undoubtedly the biggest threat at the combat and tactical level. The retreating soldiers of the Western Expeditionary Army only had to plant a few of these weapons of mass destruction in the road to scare the pursuing Elta forces, or force them to wait until the expiration date of complete safety had elapsed.

Offy Mondrich probably didn't expect that the willow tree that his craftsmen had inadvertently planted would accidentally become the Amazon rainforest, and it would become the number one problem in the attacking force of Cierta. Fortunately, his thinking was not enough to jump to the level of railway guerrillas and tunnel warfare, and he was even more fortunate that he had not read "On Protracted War", otherwise it would still be a big trouble. If he's smart enough, any Magic Lance team will be superfluous - he only needs enough Magic Powder Mines to survive the harvest period threatened by Elta's Magic Powder Mine.

At that moment, the staff officer forwarded the news back to the staff headquarters, and the samples were transported back to Mendong City with Yafizlna. The General Staff immediately issued an order to all the troops of the Elta Army on the march: to set up the necessary front line, at a certain distance from the marching ranks. The front team should pay attention to the color change of the soil under their feet at any time, and if they find any abnormalities, they can notify the rear team to stop the march immediately.

Except for this engineering unit that came to investigate because of the strange scene captured by the gunboat, the other units of Elta did not have sappers equipped with metal detectors, so they could probably only take a detour in this case.

It turned out that their approach was somewhat redundant. Due to improper setting of the spring length and excessive standard deviation, only a dozen of the fifty sets of magic powder mine components brought back by Yafizerna were able to start normally under heavy pressure. And the previous few rains made the soil above the few magic powder mines that had been buried around the stronghold on the front line of Xierta become heavier by moisture, thus accidentally pressing the magic powder mines. The springs made of bronze were also useless, and some were even scrapped by the pressure of the soil for several days, while most of the Cierta army was still marching on the road with military songs.

The magicians who planted the mines also did not set up the Magic Powder Mines at the safe distance given by the craftsmen under Ouffel Mondridge. It doesn't matter if it's remote, but it's a big problem if it's closer. Dust mines that are activated by mistake often blow up the surrounding soil, and it is not uncommon for shockwaves to blow up the surrounding powder mines. It doesn't matter if it's not crooked, if the combination of the lid and the barrel body is crooked, it will be a big mess in the world. The spring is misaligned and drills out of the groove, and the pressure is transmitted directly to the short wand.

Some of the magic powder mines planted according to the protocol also encountered the same problem. In fact, even the craftsmen of Ofer Mondrich did not set up enough safety distances - they did not take into account the difference between the soil quality of the Hilzi Shooting Training Range and the soil quality of the border area of Cielta......
