"This is a 'jack round' specially equipped with a grenadier canister. Pen? Interesting? Pavilion wWw. ｂiquge。 info" Roland handed over the design drawings of the special grenade in due course.

Kafta glanced at the dwarf alchemist in surprise, and then smiled knowingly: "I haven't seen a jack shell yet, but if you think the total weight of the shell doesn't exceed 30 pounds, an ordinary adult can easily move it." ”

"It's a pity that there is still a little bit of research and development of the Jack bomb...... Minor difficulties. Mr. Jack took out another drawing and handed it to Kafta, "Mr. Roland wants to equip the grenadier with a large grenade with a tail stabilizer, I am not familiar with the tail device, and I am still testing what structure works best." ”

"Oh, I have a bit of experience with this problem, not long ago in the war against piracy, Mr. Roland proposed to the White Gull Harbor Arsenal to produce aerial bombs with tail stabilizers, and Mr. Sukhoi successfully completed the work, and I had the privilege of participating in the work at that time, and all the test data were recorded......"

Kafta pulled out a thick notebook full of data and graphs from his storage bag and spoke to Jack. The two chatted for an hour before deciding on the improvement plan for the Jack bomb, as for putting it into mass production...... I am afraid that they will not be able to spare their energy in the short term, because Roland has a more urgent task for them to complete.

"Mr. Kafta, please take a look at this drawing, we need to destroy the defensive position of the 'Dragon's Eye' with the help of the secret weapon depicted on the drawing." Roland placed a thick stack of drawings on the table, and his eyes inadvertently swept out the window, the "Dragon Point Heights" in the moonlight were bright, the granite forts were densely covered on the high ground, and the thick barrels cast heart-palpitating silhouettes in the night.

Kafta picked up the drawings and flipped through them quickly, his face became more and more eccentric, he looked up at Roland and Jack, and asked in disbelief, "Are you guys joking?" The size of the naval guns is not so exaggerated, and you are trying to use this thing to fight a land battle, it's crazy! ”

"We're not crazy, we're just going to pull this cannon to the front line and bombard the dragon-blooded mongrels on the other side." Jack said confidently.

"It can't be! How heavy does this big guy have to be? ”

"The cannon weighs 40 tons and has a barrel diameter of 12 inches – according to Mr. Roland, this size is equivalent to the main gun of the 'Tower in the Clouds'." Jack unthinkingly revealed the data of the super cannon, "The Magic Crystal Cannon Core has a constant 6-ring 'chain lightning' as an excitation device, firing a special grenade weighing 1,000 pounds, with a range of 20,000 yards and an effective kill radius of 50 yards. ”

"You can't transport such a heavy weapon to the plateau!" Kafta said flatly.

Roland smiled, "Actually, we did ship it, and there is more than one. ”

Kafta stammered, speechless in shock. The caliber of most of the land artillery is inferior to that of naval guns, the main reason is that the road traffic is far less light than the sea transportation, and the current military logistics mainly rely on animal traction such as mules and horses, and he really can't imagine how to transport this behemoth with an inner diameter of up to 12 inches to the Kitland Plateau, let alone deliver this steel giant to the front line.

"Just look at this breakdown structure diagram and you'll get the idea." Jack showed another drawing, "The engineers at the Icewind Dale Arsenal are probably the most agile and eclectic dwarves I've ever met, and they designed the Super Cannon with transportation in mind, which can be split into hundreds of parts and transported separately and assembled at the position. ”

"Well, that's what I've thought of, but what happens when it's assembled? Do you want to use this super cannon as a fixed battery? "Actually, you don't need a fixed turret, you need a field gun that can accompany the legion and change the firing position according to the battle situation!" How are you going to move this big piece of iron? ”

"We use the Highlands to tow the cannon."

"That can't be! Highlands or any other animal can't drag it, not even the dragon! ”

"Eight-headed Highland Beasts...... Roland smiled mysteriously, "plus two railroad tracks." ”

"Huh? Rail? How can you ...... like this," Kafta touched the back of his head and thought for a few seconds, and then suddenly realized, "It turns out that this is the so-called train cannon!" ”

"We have two 12-inch train guns, model ......" Jack looked at Roland and continued with a smile, "We named this type of train gun 'Roland's Hammer', No. 1 has started to assemble, and No. 2 is still lying in the warehouse. ”

Roland shrugged, frustrated at Jack's forcible naming of the train cannon after him. Because he named the grenade used in the grenadier "Jack Bullet", this kid used this way as a retaliation, which made him say something good.

"Got it, so what can I do for you?" Tafka was full of anticipation, his face flushed with excitement.

"The train cannon has not yet undergone actual combat testing, especially the barrel, which is too large and heavy, and has to be disassembled into twenty steel cylinders with nested screws for transportation. To be honest, we don't know what to do, and that's when we're going to need the support of a trap warlock. Roland said.

Kafta's eyes lit up when he heard this, and he nodded repeatedly: "No problem! That's no problem at all! Dealing with mechanical failures and increasing the strength of metal is exactly what our warlocks are capable of eating, Mr. Roland, Brother Jack, don't worry! My team and I can make a military order to ensure that Roland's Hammer never stops roaring until it destroys all enemy strongholds! ”

"Then please, Mr. Kafta, the conditions on the front line are difficult, and if there is any need in life, just bring it up, and I will do my best to provide security."

"Nothing needed, I just want to get to work as soon as possible!" Kafta rubbed his hands excitedly, "Mr. Roland, I'm afraid it's hard for you to understand my feelings, having the opportunity to touch the 12-inch train gun...... Such a great weapon is the best reward for a mechanic. ”

Jack nodded in agreement, "When I walk into a warehouse full of alchemy, gunpowder and cannonballs, I will also feel a great sense of satisfaction - this life is worth it!" ”

Roland is funny and a little moved, maybe this is the "romance of science students" in the fantasy world.

PS. The sharp weapon of the Kolas Legion to remove the pillboxes and turrets - the magic crystal train cannon "Roland's Hammer"

A 12-inch smoothbore howitzer weighing 40 tons and a caliber equivalent to the main gun (305mm) of the "Tower in the Clouds". The constant 6-ring "Chain Lightning" of the magic crystal cannon core is used as an excitation device, firing a 1,000-pound cannonball with a range of 20,000 yards (about 18 kilometers) and an average damage of 16d6; The explosion radius is 50 yards and spreads. With the help of the Warlock, it only takes 2~3 minutes from loading the shell to completing the launch.
