Roland patted the little dwarf on the shoulder and gave him some encouragement: "Don't forget if Sasha and Vanka don't go, I'm very interested in your new invention, so let's open my eyes." Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ”

Jack was overjoyed and hurried out with him. On the way, Jack told him about his work in the barracks over the past year, and in short, he was a big butler who managed the armory, and in his spare time he was engaged in some inventions and creations. As an ordnance officer, he had no interest in cold weapons, but was only interested in improving artillery technology and inventing new bombs, and he achieved a lot of success in this regard, so he won the respect of the whole legion, and because of Roland's connections, he became acquainted with two bad friends, Ivan and Alexander, and often fooled around eating, drinking, and having fun together.

Gnomes are optimistic by nature and sometimes seem overly optimistic. This is where Jack's problem lies, even if a new invention is still flawed, he can't wait to show it off, and as Ivan and Alexander feared, he will always drop the chain at the critical moment, and even make many jokes.

At the beginning of his hometown in the town of Big Rabbit's Nest, Jack was criticized for his unsuccessful and dangerous inventions, but when he arrived at the Kolath Legion, the new environment was much more tolerant of him, and Rudolph did not mind that he failed even a hundred times in a row, and did not hesitate to give him recognition and praise as long as he succeeded one hundred and one hundred times.

Jack lived up to the tolerance and expectations of His Excellency the General, and during the year he made a fruitful contribution to improving the accuracy of artillery fire. He found that the empirical formulas and parameter tables used by artillery observers were too complicated, and they could not do this job without a good mathematical foundation, and on the battlefield where the guns were rumbling and full of dangers, the observers must also have excellent psychological quality when processing various data, otherwise a little panic would lead to calculation errors, and the gunner's adjustment of the shooting elevation angle according to the wrong data would only lead to mistakes on top of mistakes, and the shells fired could not hit the target, and the more terrible consequence was to accidentally injure comrades. Incidents like this happen from time to time during daily artillery training, and this is undoubtedly a painful "tuition" for a newly formed artillery unit.

"I had a disagreement with old Yuri on this issue...... By the way, you haven't met Yuri Popov yet, have you? He's our leader, a dwarven veteran who is proficient in artillery, not bad, but a little stubborn. Jack took off the sign on the door of the temporary workshop with the words "Military Heavy Land, Idlers are not allowed to enter", opened the "Secret Lock" and invited Roland in, while saying happily, "Yuri thinks that observers can only improve their computing ability by constantly strengthening repetitive training, but I feel that the traditional calculation method is not reasonable, many formulas can be simplified, and some data are dispensable, so I rewrote a simpler data table, and the observer only needs to use the height, angle, wind, and The temperature and other field data can be compared to the table to quickly determine the shooting results, and Yuri thinks that my simplification method will introduce an intolerable error, so we use two cannons to verify it. ”

"It turns out that you were right." Roland looked at the bottles and cans and scraps of paper that filled the room, there was an uneaten piece of dry bread on the desk, and a swarm of rats were greedily eating supper around the bread.

"As you say, the intensive reading of the shelling calculated according to my simplified method is not inferior to the traditional method, and the efficiency is greatly improved, and Yuri's old stubbornness has to be convinced." Jack waved his broom away from the rats gathered around the table, "Damn! Looks like I'm going to have to get a cat and help me deal with these pesky mice! ”

"You're an advanced alchemist of the mage, you should have a magic pet?" Isn't the magic pet just used to see the home nursing home to remove insects and rats......

"I once raised a badger, but unfortunately it died in an experimental accident, and later I also raised a crow, and I also hung up in an experimental accident, which hit me hard, so I don't want to raise any more magic pets." Jack said melancholy.

"Magic pets" are small animals that mages and warlocks summon to their surroundings with their magical powers, and can grow with their owners. There are similarities and differences between "magic pets" and "animal companions". Druids and rangers can directly tame birds of prey such as wolves, bears, falcons, and leopards as animal companions, and have the ability to protect their owners in battle; Mages and Warlocks' pets are more intellectually growable than their animal companions, but they are generally more fragile, have no combat power worth mentioning until they grow, and are only relatively intelligent compared to ordinary animals, so they are easily injured or even killed. Summoning a pet itself requires an expensive spell casting material, and the death of a pet can also cause damage to the owner of the spirit, so some casters who often work in dangerous jobs would rather not have a pet for them.

Roland understood Jack's distress and gave him another idea: "You go to the Shooter Camp and ask the rangers for help, they are very good at dealing with nasty critters like rats. ”

Jack shrunk his neck and said a little embarrassedly, "Forget it, I don't dare deal with those hot girls...... They're too tall for me, I don't like to look up and talk to girls, well, that's a terrible feeling! ”

Roland couldn't help but laugh when he heard this: "I'll talk to Mila about it later, and ask her to take the time to help you train a good cat who is alert enough to catch rats and escape experimental accidents in time." ”

"Thank you in advance, I hope that cat is as good as you say." Jack tosses the rat's leftover bread in the trash and opens the cabinet to show Roland what he has been working on for the year. Rather than improving the manual of artillery calculations, the dwarf alchemist devoted more energy to his profession - the development of new shells and bombs. Jack has a lot of ideas, but most of them have not yet turned into fruits, and there are a bunch of half-finished products in the cupboard, each of which is full of whimsy and dangerous at the same time, and there are only two things that have actually been completed, one is the "flare" that has just been verified in actual combat, and the other is the "fireball bomb" that he has spent the most effort on.

There are usually two ways to "pour" a cannonball with magic, one of which is to refine the cannonball as a whole into a magic artifact, and then bless the spell. For example, the "infusion dissociation bomb" that was widely used in the Astral Naval War was created in this way. This method is universal and can attach almost any spell to a cannonball, but it also has the drawback of being too expensive to build for high-level spellcasters.

Making this kind of infusion cannonball is equivalent to making a disposable "staff", and a high-level magic item like a staff can only be made by a level 12 caster, plus the infusion spell itself is time-consuming and labor-intensive, and the final cost of creating a bomb is even more expensive than the same weight of gold as a bomb!
