"Margaery Tyrrell?" Egger raised an eyebrow and chuckled, "No, I'll talk about it when I'm done with my work and I'm free." ”

Little Rose, can you be considered a friend?

Judging by the frequency and amount of money she has made to trade with the Night's Watch industry after she left King's Landing and traveled north to the Wall, there is no doubt that she is, but to the Night's Watch Commander-in-Chief, who is now under the Dragon Queen's command, she is by no means a newcomer.

Iger had even guessed that she was not acting with the official mission of the Riverlands, but had secretly come to find out what was going on with her, but unfortunately, the two of them were the original nobles who had been replaced by the fake, and the other was the leader of a new force that supported the queen to break the wheel of history, and they were destined to have no common language and cooperation goals with each other.

......

(Even if the queen is reluctant to recognize Prince Aegon for fear of affecting the succession, such a strong reinforcement in the Riverbend Lands that cannot threaten her status should be actively fought for, right?)

Nina didn't quite understand why Egger was so cold, but she at least understood that her man was much more powerful than her, and that she had better not talk too much about what he thought and decided to do.

As a result, the Tyrells' jewel was completely ignored, and the camp administrators gathered around Egger to report more about the offensive and defensive posture of King's Landing before his arrival, and accompanied him into the Blackwall Fortress, starting his tour from the saltpeter warehouse.

Because the war cut off the north-south communication route, the ship that Iger personally sailed south to retrieve was the only batch of large-scale supplies provided to the Great Wall by the Southern Night's Watch Industrial Park in the past two years. However, although the transportation was suspended, the communication did not stop, and under his repeated orders, the saltpeter yard maintained uninterrupted production at full speed until the temperature was too low to start work anymore......

Compared to other civil structures inside and outside the castle, the saltpeter storehouse is small in size, but it is exceptionally solid and heavy - it is made of stone from wall to ceiling, and it is like a small castle with reduced scale and undiminished defense. Because the walls are so thick, the interior space seems to be very small, and the damp-proof shelves made of stone and rising from the ground are densely packed with large jars of purified saltpeter, and the amount of nitrate stored in this room alone is probably more than the Night's Watch army used up in the entire war against the strangers!

"There have been a lot of accidents and casualties in handling and storing this thing, but after a few bloody lessons, we now basically know how to store it safely. The building prohibits the entry of any unprotected light sources such as torches, nor does it contain any combustibles, and it is designed with ventilation tunnels to cool down – of course this is only useful in summer and cannot be seen by the eye. Nina's brother Neil explained that he has always been in charge of this matter, "For safety reasons, they can't be stacked compactly, so there are only 200 cans in each warehouse." And such a warehouse, there are two identical ones in the Black Wall Fort. Originally, I was going to build a fourth, but then I found out that there were dozens of extra cans, and the temporary warehouse of the nitrate factory could be placed, and anyway, production had stopped and there was no longer a place to be used, so there was no more waste of money. ”

Those are inconsequential details, Iger nodded in approval, approached the shelf, carefully picked up a large clay pot and weighed it a few times, it was heavy, and it was estimated to weigh thirty or forty pounds.

Even if each can of 30 catties of nitrate is good, more than 600 cans, that is nearly 20,000 catties, ten tons.

This is just saltpeter, which expands out several tons when mixed with charcoal and sulfur to make gunpowder.

A dozen tons of gunpowder!

Even though he had already estimated the approximate number, Egger couldn't help but feel a little excited.

It is true that this weight is not enough for the people of Egger's hometown to consume fireworks on the first day of the Lunar New Year, but in the current era when firearms have just been born, these four saltpeter warehouses can be regarded as inexhaustible gunpowder mines in a short period of time!

Iger didn't have to worry about running out of gunpowder now, but had to hurry up and get more weapons that could consume gunpowder.

"Cobain, I'll leave these four warehouses to you. ”

"Wrap it up on me, sir. Cobain still had a kind old man's smile, not at all like a man who had just been authorized to take over one of the world's gunpowder raw materials. The so-called handover to him naturally asked him to turn all this nitrate into real gunpowder - just because the gunpowder formula was still in a secret state for the time being, and it could not be said explicitly.

Iger put down the large clay pot and calmed down his excitement: "Alright, let's go to the foundry and have a look." ”

As the second stop on the inspection, the Blackwall Fort foundry was completely incomparable to the one in Houguan Town, both in terms of size and staffing, the latter of which had been clearly planned for the purpose of casting artillery from the moment construction began. And the former...... It is said to be a foundry, but in fact it is more like a plus-size blacksmith shop, mainly responsible for making metal parts for various production equipment in the industrial park, and then producing some iron weapons and armor from time to time, and supplying some iron farm tools to the insiders.

However, metal processing is metal processing, and the low level of science and technology has the advantage of low - that is, the division of labor in the industry is not detailed to the extent that it is difficult to be compatible and replaced. In the eyes of the layman, casting artillery and forging swords are naturally not the same thing, but in the eyes of the insider, most of the things that should be there here are not lacking, as long as the drawings and personnel are provided, and the facilities are slightly modified and some tools are added, the same workshop can become the second firearms arsenal in Westeros and the entire world of ice and fire in an instant.

Egger brought Cobain and the core technical personnel from the land grant to the south for this purpose.

Houguan Town, a border town at the end of the world, has completed its mission as its birthplace, although its identity as the "Northern Industrial Center" and Egger's base camp is still unshakable, but it will not return at least in the short term. The second, third, and fourth generations, larger and more advanced artillery will all be developed and produced here, the Night Watch Industrial Park, and will be transported to the battlefield nearby, roaring to smash the old era!

People with dreams and ambitions are full of energy, and with a large number of subordinates, Iger goes round and round in and out of the Black Wall Castle.

He first determined the design of transforming the casting and forging workshop into an artillery production base, and then went to visit the newly trained security team in the industrial park in the past two years, which is actually the reserve officers, and formulated a plan to integrate them into the land-grant army, and then planned two other gunpowder raw materials- After all this was done, he rode out of the industrial park with great interest, and went to the wilderness not far away, where he set up the site for the artillery test site, and tossed and turned busy until nightfall, and his stomach growled, and then he returned to the Blackwall Fort with great interest, ready to go to dinner.

"The second-generation artillery will definitely not be able to catch up with the attack on King's Landing, and the current industrial park is crowded with soldiers, which is not conducive to secrecy, so I am not in a hurry to start work, first make preparations, and wait to take King's Landing, after the garrison leaves this place, I will close this area and divide it into a forbidden place, and the specific security work will be set up separately to be responsible for it when the time comes. ”

Even though his mouth was dry and he entered the restaurant of Blackwall, Egger was still gushing about his plans for the renovation of Blackwall...... Until a slightly familiar Miaoman figure suddenly appeared from the side, interrupting his free speech with a soft and tactful, complaining but not angry coquettishness.

"Commander-in-Chief, you really have a lot of opportunities, you can tell me to wait!"

Margaery Tyrell couldn't wait for Egger's appointment, so she simply stayed in the high-level staff restaurant where he was bound to come, and came to wait for the commander!
