Roland himself is not a technical powerhouse, his advantage is only that he is well-informed, and is only responsible for providing reference ideas for solving problems, as for how to turn his ideas into products, it depends on the efforts of Jack and Kafta's team.

At present, there are more than 200 researchers at the Far Eastern Academy of Military Technical Sciences, half of whom are alchemists and half are mechanical warlocks, all of whom are the top elites of the industry. Solving a small canned packaging problem is obviously difficult for this group of geniuses.

Roland issued the task at the beginning of September, and just a week later, he received good news from Jack: the "Canned Food Research Group" specially established by the Research Institute has completed the commission of His Royal Highness the Prince, and the "Anti-rust Iron Box Canned Food Box" and "Star Plastic Packaging Bag" have been successfully trial-produced; In contrast, the latter is lighter, but the cost is three times that of the former, and it is up to His Royal Highness the Prince to decide which canned food to choose.

Jack sent samples of both boxes with the letter. Tin cans look similar to their counterparts on Earth. Most of the canned tin boxes on the earth use electroplating to prevent rust, and the world of Varess does not have this technology at present, and it uses enchantment anti-rust technology.

When Kafta tried to produce tin cans, he found that it was necessary to prevent the tin cans from being rusted by the humid air, and also to prevent the corrosion of the inner wall of the cans caused by acidic food. To this end, he specially improved the existing anti-rust mechanism, creating a "Kafta anti-rust technique" named after him. This spell is both a 1-ring trap and a 2-ring arcane, and permanently protects metal objects from rust caused by natural factors, but has no effect on rust caused by magic or supernatural forces, such as the druid's 4-ring nature magic "Rust Claw".

Enchanting each box of cans is undoubtedly costly, and in order to reduce the cost of enchantment, Kafta further improved his invented trap by adding edible vegetable oil as a casting material. The 10-gallon vegetable oil is subjected to the "anti-rust technique", and then the tin sheet used to process the canning box is left in the oil for a whole day, and then the tin is removed and wiped clean, and the tin is automatically enchanted. This method of enchantment greatly reduces the cost, the only problem is that the anti-rust oil that penetrates the surface of the iron sheet will slowly evaporate over time, and it will be free from rust for ten years, and it is not guaranteed after ten years.

Military cans do require a longer shelf life, but a shelf life of ten years is long enough, and Roland finds it acceptable. It's not like a certain country on the earth, the canned corned beef stockpiled during World War II still dares to take it out as military rations after half a century, and it is miserable enough to be a soldier in this kind of country!

The second kind of box, Roland also took a look. The stellar and silk compounds, soft and unusually tough, are far from being easily torn apart like plastic packaging bags on earth, and must be slashed in the same direction with the help of a dagger, repeated many times before they can be cut and poured out of vacuum-packed food. In terms of practicality, flexible packaging plastic bags are actually better than tin cans, which are convenient for individual soldiers to carry rations or logistics transportation. However, the two raw materials of star quality and silk are much more expensive than iron sheets, and military food packaging bags are a very large demand for consumables, and it is not convenient to recycle used packaging bags on the battlefield. War is a greedy monster that constantly devours money, and the Far East is not rich, so Roland has to be careful at every turn.

After receiving his feedback, the "canned food research team" immediately pushed forward with the next step of research work, so that two weeks later, in the early morning of September 26, Roland had just gotten up when he received a letter from Jack, asking him to go to the Military Technology Research Institute to accept canned samples.

"Coming soon!"

Roland hurriedly replied to a magical text message, he didn't even bother to eat breakfast, and after washing, he rushed to try the canned food!

Most of the alchemists who worked at the Military Technology Research Institute, led by Dean Jack, had a similar background: they were born in the "Big Rabbit's Nest Town" and graduated from the Alchemy School of Colasburg University. On top of that, they also have a common nature among the dwarfs – a love of food!

These multi-talented dwarf alchemists poured their love of food into their work, and they tried to produce six types of military cans, all of which were on the table waiting for His Royal Highness to taste.

Roland picked up the dagger and opened the can all the way, feeling quite cool! After tasting canned corned beef, canned ham, canned smoked fish, canned mixed fruit and canned jam with bread, Roland gave them all a good review! It wasn't until he opened the last can that the white flowers, plump and oily fat meat were immediately exposed in front of his eyes, and he couldn't help but burp in fright!

"What the hell is this?!"

"Your Royal Highness the Prince, this is a special delicacy in the northern snowfield region, pork fat meat marinated in a large amount of rock salt, used to eat with bread, more delicious than ordinary butter, and can provide a lot of calories, quickly replenish the physical strength of officers and soldiers, it is really delicious, don't you taste it?" Jack eagerly recommended to Roland.

"Pickled lard ......" Roland's hand holding the fork trembled slightly, and tried to attack the box of cans several times, but finally failed. The taste of this "hard dish" was slightly heavier, and he couldn't stand it, so he had to decline Jack's kindness.

Except for the last "dark dish", Roland was very satisfied with the several canned foods he tasted. Even pickled pork fat oil, although it is not to his taste, it is indeed very popular with the public in the Far Northeast, and such high-fat and high-calorie food is indeed needed to fight in the war, so Roland's generosity can be retained.

With the current industrial capacity of the Far East, the production of canned food is not "high-tech", and the only slightly troublesome thing is the anti-rust enchantment link. Fortunately, since the completion of the Far East cloud network, the concept of "magic bank" has quickly spread to thousands of households, with the advent of the "cloud card" in early 1624, now ordinary people can also buy or rent cloud cards to link the cloud network.

With the convenience of the cloud network, people can borrow spell slots or purchase spell casting services at a lower cost, and one of the major bottlenecks restricting industrial development - the exorbitant price of enchantments - can be solved.

Today's Far Easterners have a much more favourable entrepreneurial environment than any other country in the world, and this advantage, in turn, has greatly stimulated people's enthusiasm for entrepreneurship, and whenever something new is invented, imitators always flock to it.

After Roland accepted the tin cans, he wanted to create a state-owned cannery funded by the government to provide military cans for the troops, but the Minister of Commerce, Evgenia, put forward a different point of view at a cabinet meeting.
