Gunpowder, black powder to be precise, one sulfur, two nitrates and three charcoals. The formula is simple and smooth, there are many people who can memorize, this is the proportion of ingredients involved in the reaction, and there will be a better quality ratio when actually formulating, Egger also has an impression of this: 2:15:3. In addition to remembering the formula, he also knew that "sulfur" and "charcoal" were actually elemental sulfur and carbon, and "nitrate" was potassium nitrate, and it was not a problem to write the reaction equation of the explosion - there was nothing to show off, and the basic knowledge that could be mastered in high school.

But it's one thing to know the principle, and it's another thing to immediately come up with a lot of gunpowder that can be put into practice—he wasn't a chemistry or geology major after all, and he hadn't done it himself.

Even if you do it...... He wouldn't have gotten the gunpowder out right away.

The simple reason is that this thing is too destructive, and it is currently "under the fence", in fact, it is covered by the Iron Throne and especially its official representative, Eddard, although the latter may not even realize it. This objective fact will not change just because Iger is familiar with the plot and even secretly "saved" the former. Before you have control of a force that is obedient and completely your own, getting gunpowder out is simply making wedding clothes for others. As long as the news leaks, the new invention will be used in the war between the ruling class of this world in a matter of minutes - and the explosion is not long-sighted, and he, a "neutral" night watchman, wanders The biggest reliance between the various forces is balance, once this balance is broken, the battle between the seven giants will start, except for the northern army may be merciful, no one else cares what kind of human guardian or guardian of the Great Wall. Once it is affected by the war, the loss of the legion's assets is secondary, and if you are unlucky enough to kill what you brought into this world, it will be a big joke in the world.

As a traverser, Iger will not refuse to fight with the beautiful opposite sex, as for experiencing two armies playing artillery on the battlefield...... Although it sounds like a "man's romance", if you participate in it, forget it.

......

The most ideal future is to find a reliable thigh or simply stand on your own after your own power is formed...... At the most critical moment, the weapons of mass destruction will be sacrificed: if civil strife does not break out in the Seven Kingdoms in the end, then put into actual combat when the strange ghosts are really attacking, and if the war still occurs, then take advantage of the chaos and quickly let them experience "the equivalent is the truth, the range is justice" before the various parties can also obtain gunpowder technology through means, punch the ghosts, snakes and gods of the Seven Kingdoms, and eradicate all opponents and threats with devastation. After that, he quickly managed to get rid of his status as a night watchman and reach the pinnacle of his life in one fell swoop - when the time comes, it's up to him whether he will continue to enjoy his life in the other world or find a way to travel back.

Alas, Iger couldn't help but think of the standard configuration of crossing the farm: if the soul pierces a certain prince, there are subordinates and fiefs at the beginning, and things are not so complicated.

Egger courted the pyromancers, in addition to trying to gather a few of them for their own use, and to make sure that they could rely on these primitive chemists to get gunpowder quickly if necessary, a more direct factor was to contribute to the defense of the Wall: wildfire, a super dangerous thing in the warm south, but in the cold of the Wall, with enough care, it could be used directly as liquid explosives.

While Iger was waiting for the first Night's Watch factory to be completed and put into operation, he tinkered with the bottle of wildfire he had bought. Pour a few milliliters out each time, all kinds of toss and try.

"Don't get so close," Egg told Arya, who was staring at her death with interest, "if I have a fire on me, splash me with the bucket of water over there!"

The girl giggled and agreed, in her eyes, it was normal for her adventurer master to want to play with fire.

Protected by caution and precautions, this little death did not hurt anyone, and soon, Iger came to some conclusions:

First of all, it's much less dense than water, which is nonsense, light oil is necessarily lighter than water - not only can it float on water, but it can also burn against the cooling effect of water, which is why Tyrion was able to use it to burn the Stennis fleet in the original story. Secondly, this thing is really super flammable - except that the body temperature can't ignite it, it barely has the slightest time to settle down: it drips on the hot ground and catches, it basks in the sun for half a minute, it catches, you snap your fingers near it, rub your fingers between your fingers to generate a little heat, and it catches ...... Despite the lack of a thermometer, after several attempts, Iger made a judgment: temperatures above 50 degrees Celsius would cause the thing to spontaneously combust.

In addition to being highly susceptible to ignition and spontaneous combustion, it also has a very low surface tension, giving it the property of being able to quickly soak and seep into the gaps no matter what it touches, a feature that is almost terrifying to the point of death for a flammable liquid.

Good stuff, look forward to the scene when it's set on fire in the horde of ghouls.

......

Iger waited for the pyromancer, talked to him, and invited him to the north to serve the Night's Watch...... Denied.

No, when it comes to working for the Night's Watch, everyone immediately has a lot of bad associations, and this idea is even more ingrained in the minds of the older grades. No matter how he explained, Fang Dou refused to let go in the slightest, and the matter was finally abandoned - but Iger was not discouraged, he was still only a small night watch officer, and it was naturally impossible to do anything smoothly. But as long as it takes some time, when the Night's Watch industry develops, and then forms a solid community of interests with the nobles in King's Landing and even the royal domain, the combination of money and power will produce a terrifying power, and at that time, he will once again find the alchemists and use coercion and inducement to give them an "offer that cannot be refused".

The first investment was finalized, and the future seemed bright, but just as Iger was looking forward to the future, a sudden news made him a little panicked. During a routine "emotional exchange" with his little apprentice, he heard a new piece of heavy news from the girl.

......

A series of important nobles in the valley, such as Jon Royce, Count of Runestone, Anya Weywood, Countess of Iron Oak City, and Jewood Hunt, Earl of Longbow Hall, quietly united to form the Alliance of the Righteous Ones, concentrated the most elite forces of their respective families to launch a mutiny, designed to cooperate with the outside, and captured the Blood Gate at a very small cost. Tully hands over Duke Robert the Younger and is put on trial, and is jointly raised and educated by several families to educate the future ruler of the Vale!

The declaration signed by the alliance in Runestone had been sent to King's Landing, and Arya learned about it from her father's chat with his staff, and then spoke unsuspectingly to Egger, making him the second group of people in King's Landing after the core of power to know about the breaking news.

＊＊＊

The second Olympics, fierce, really fierce, not to lose Weima Royce's stunned father, he is really not soft at all when it comes to doing things, and his appearance is a big deal!

Egger had originally spread rumors just to bring down Littlefinger, but once unleashed, it was like opening Pandora's box, and now, the demon had completely escaped the control of its creator and ran out of King's Landing to wreak havoc in the valley. The valley, which used to stick to its own territory in the War of the Five Kings and did not participate in the war, and its strength was not damaged at all until the end of the war, has now become the first place to cause chaos?

Emotionally, Egg gloated over the siege of Eagle's Nest by Lyza's mad, but now he's playing a game of money: raising money with financial means and then starting a business with advanced technology. And this kind of game, no matter how closed and inaccessible the world is, is closely related to everyone and affected by everything that happens in the world at every moment.
