Tograce Fortress, Command Room.

A thick metal box was carried to the table by two personal guards, and immediately attracted the attention of the two old men.

There are several heavy mechanical locks hanging on the metal box, and the surface is wrapped with more than a dozen chains cast in special alloys, and seals are covered with seals - all of these details show people how important the things contained in this box are.

One of the old men nodded, and a deputy with the rank of major general next to him immediately stepped forward, took out a large number of keys from his pocket, unbuttoned the mechanical locks and chains one by one, then removed the seal, and carefully opened the box.

The box is not a rare treasure or a highly precise mechanical device, but a barrel that is so ordinary that it cannot be more ordinary. There are even traces of gunpowder burning on the surface.

"What is this? Is it just a gun barrel?" One of the old men asked in confusion.

"This is the barrel of a 'Minault 1' rifle." The adjutant replied.

The "Minotao Type 1" rifle is a single-tube rifled flint gun with a barrel length of 75 cm, a caliber 11 mm, and an effective range of between 350 meters and 400 meters. It is the standard firearm for the heavy infantry troops of the Northern Federation.

"Is there anything wrong with this barrel?"

"We found some special information inside the barrel..." The adjutant said, pushing a precision refraction prism to the side of the table. Through this prism, people can clearly see the internal structure of the barrel and one of the details.

"This...what is this?"

The enlarged image is projected onto a snow-white curtain, and there is a clear milling mark at the ends of the four rifles. Under normal shooting, it is difficult for the barrel to wear out at this position, so the milling mark is obviously something that someone deliberately does.

"This is the image restored by the Technical Department." The adjutant presented another rubbing, with a square mark on it, and the content of the marking was composed of four square "Tang texts".

Tang Wen, that is the official text of the Eastern "Tang" Empire. This text appears on the barrel of the Northern Federation Army, which immediately casts a shadow on the expressions of everyone in the command room.

"Tangwen?!...These four words are...'Longmen Workshop'?!" The old man murmured. As a hereditary aristocrat, they have received some of the education of Tangwen, and they still know some commonly used Tangwen characters.

"Can't it be... behind these barbarians, the Tang Empire is supporting them?" Another old man's tone was also full of shock.

The Longmen Workshop is affiliated to the largest private consortium of the Tang Empire. Although it is a private consortium, without the tacit approval of the Tang Empire, the Longmen would never be able to interfere in the war between the two countries. Once this kind of business is not handled well, it will easily lead to serious diplomatic events.

"No... don't make a conclusion first, and immediately send the barrel and rubbing back to the imperial capital as quickly as possible. This matter will be decided by His Majesty the Emperor himself!"

If the Tang Empire is really behind the Northern Federation, then things can be summarized in more than just the word "trouble".

As the overlord of the Eastern Continent, the Tang Empire was far above the Rhine Empire in terms of economic strength and military strength. According to reliable information, the Tang Empire alone had nearly three million soldiers. On the other hand, even if the Rhine Empire mobilized nationwide, it would probably not be able to gather so many troops.

Not only the gap in the number of troops, but also the Tang Empire has been ahead of the Rhine Empire in the development of scientific research and technology. As for the top ink crystal array technology at present, the Rhine Empire just used the ink crystal array to actual combat. A hundred years ago, the Orientals had already regarded mo crystal as an important strategic reserve material.

If the Rhine Empire and the Tang Empire go to war, there will be no suspense in the outcome.

Fortunately, there is a towering Xiya Mountain Range between the Eastern and Western continents, forming a natural barrier. The Xiya Mountain Range is above 7,000 meters above sea level, and the climate and environment are harsh and harsh. No human army can pass through this mountain range, even airships cannot. The coldness at a height of 10,000 meters is enough to freeze the entire airship into an extremely large popsicle, and then fall from the sky with a bang.

There are only a few commercial roads that can be used by people in the entire Xiya Mountains, and no caravan entering the Xiya Mountains can guarantee that they will remain full when they come out.

It is precisely for this reason that Tang, a country far away in the East, is always covered with a mysterious veil in the eyes of Westerners.

...

But the Permafrost Islands are different. If you walk on the sea route, although the route is very far away, you can bypass the Xiya Mountains, a natural barrier between the East and the West... In fact, if the Tang Empire wants to provide material assistance to the Northern Federation, it only needs a fleet that can withstand the wind and waves of the sea - a large cargo ship with standard transportation volume can transport hundreds of thousands of such barrels, which is enough to arm everyone in the Northern Federation!

Thinking of this, the senior generals and schoolmen in the command room felt cold sweat falling from their backs, and one of them couldn't help but say, "Then we are fighting with the Northern Federation... isn't it equivalent to being with the Tang Empire..."

"Shut up!" One of the two old men glared coldly, "I don't want to hear any such remarks before the news from the imperial capital is released. If anyone brings up, he will be punished for the chaos of the military's morale."

Huangquan Training Camp, Base, Chemistry Laboratory.

The three largest laboratory benches in the laboratory have been put together to form a fifteen-meter long table, but despite this, the table was still squeezed by various bottles and jars, so there was almost no gap. Ashes even had to move the alcohol blowtorch and the iron rack table to the chair and squat on the ground for experiments.

The liquid in the flask had already started to boil, and a faint fishy smell came out from the mouth of the bottle. When the smell was smelled, the ashes immediately poured in a bottle of reagent that had been holding in their hands.

"It's good, cool down immediately and add two percent of alcohol as a stabilizer." The black bee with a gas mask guided.

"Please use dark utensils to keep the sun as far as possible." The black bee continued.
