After figuring out Yang Lin's depression, Zou Run thought about it for a while and began to prescribe the right medicine.

"I have a plan to let my brother go to Liao to buy horses and recruit more with half the effort."

As he spoke, he put out the plan in his heart.

It was originally from last year's Wanyan Agu to fight against Liao, defeated the Liao soldiers all the way, and successively won the victory in Ningjiang Prefecture and Chuhedian. Immediately in the first month of this year (1115 AD), the establishment of the "Dajin", the year name "Closing the country", the construction of the capital Ningfu, plus the name of the Great Sage Emperor. This year is the first year of the acceptance of the Eight Classics of the Jin Kingdom.

As soon as the year ended, Aguta couldn't wait to attack the Huanglong Mansion of the Liao Dynasty, which was the place where the heavy troops of the Jin and Liao sides gathered at this time, and there was a big battle immediately. Zou Run liked to read books to pass the time in his previous life, although he didn't know the historical details, but he also knew that the Liao State would be a big defeat soon, and the Liao State would be routed everywhere at that time, as long as he prepared in advance, it was really not difficult to recruit a group of Liao cavalry who were broken by the Jin army on the battlefield.

After hearing this, although Yang Lin was curious about how his own village owner could know about the Liao Kingdom from a distance of thousands of miles, there were too many things that had happened to Zou Run that were difficult to explain, and he didn't care about this one, so he just agreed immediately.

But the promise was promised, but Yang Lin was still in low spirits.

Zou Run smiled slightly, and immediately gave him a dose of tiger and wolf medicine against his "root of the disease".

"My brother is a good student, wait for me to go down the mountain in a few days, and then find a few leaders to join the gang, if there is a suitable one, let him replace his brother, and then teach my brother to lead a battalion of infantry alone, and be a decent captain."

"The owner of the village said this in front of ?!!"

Yang Lin was finally overjoyed and asked loudly, but he immediately realized that it was inappropriate, and he was eager to change his words, but he couldn't think of suitable words, which made him anxious.

After hiding for a long time, he finally squeezed out a "um" word from between his mouth and nose, which looked like a little daughter-in-law who had not yet come out of the pavilion in the east of the village.

After finishing Yang Lin, Zou Run summoned Ling Zhen again to discuss the establishment of his firearms battalion.

The two of them walked in the back hill, and behind them was a valley, where a group of people were digging something with maces and other tools.

This place is the gunpowder research and development base personally demarcated by Zou Run.

Judging from the current maritime situation, it will be two months if it is fast, and autumn if it is slow, and sooner or later the navy will have to meet the real chapter with the imperial court. There was no time to slowly develop high-tech guns, and even relatively simple guns were too late to get them, so Zou Run had to work primitive gunpowder weapons.

For example: rockets and sky-shaking thunder.

In the former, an arrow or arrow rod is cast hollow, with gunpowder stuffed inside, and the fuse is lit and shot. In this way, the so-called rocket has both the physical lethality of traditional arrows and the fragmentation effect of gunpowder explosion, and the lethality is at least tripled.

The latter is the most primitive version similar to the grenades and grenades of later generations, but the size of the earth-shattering thunder is much larger than the grenades of later generations, but the lethality is far from reaching, and the effect can only be achieved when the enemy is in a dense formation.

Ling Zhen can make and use these two weapons, and even in addition, he can use the original gunpowder weapons that have come out, such as fireballs, tribulus fireballs, poison smoke balls, etc., but Zou Run only needs the former two, in order to install the new black powder into the troops as soon as possible, and strengthen the water combat capability of the navy in the shortest possible time.

Just imagine, two ships at sea meet, shoot rockets from a long distance, both blow up and burn, and after the enemy ships endure huge casualties and finally get closer, our army when the other side gathers soldiers and prepares to jump to the gang to carry out white-knuckle warfare, suddenly throws out a few earth-shattering thunderbolts into the opponent's pile, the effect, just think about it makes people excited.

"Brother, the recipe for black powder was told to you when I was in Tokyo before, but that's just a general idea, in fact, black powder is just a big category, and it can also be subdivided into small items such as ignition powder, explosives, and propellants."

After Zou Run finished speaking, Ling Zhen behind him immediately came to his senses, he didn't expect that the knowledge in it was so great, so he hurriedly spoke out to ask for advice, and Zou Run did not hide it, and broke and crumpled the knowledge learned in later generations.

"One nitrate, two sulfur and three charcoal, this is just the most basic ratio, presumably my brother already knew it when he tried to produce it in Jiazhuoku."

Ling Zhen nodded slowly, the black powder he had made according to this method could only be used as a material for setting off fireworks, and the effect on weapons could only be said to be average. But Ling Zhen is Ling Zhen, he decisively changed the formula on this basis, and finally tried to produce a powerful explosive black powder, but he also suffered injustice because of this, and fell into a political whirlpool without knowing it.

"Among them, the sulfur ratio is increased to 70 percent, and the explosion of gunpowder can be promoted to the maximum, and the finished product prepared in this way is very good for blasting mountains and mines, but it cannot be used as propellant. If the proportion of charcoal increases, the gunpowder tends to slow down the combustion, and it can be made into ignition powder, which is most suitable for large-scale fire. The only propellant that can trigger the projectile and artillery shell needs to be accurately proportioned according to the material characteristics, which is a delicate job that requires a lot of labor, time and materials, and it is not urgent. ”

"Propellants that trigger projectiles and shells?"

Ling Zhen nodded frequently after hearing the previous words, but only Zou Run's last sentence, Ling Zhen seemed to understand whether he understood or not, as if he suddenly had a clue, but he didn't have a clue, and asked eagerly:

"How can projectiles and so-called shells be fired with black powder?"

Zou Run smiled slightly, stopped by a stream on the side of the valley, squatted down, found a piece of sand, used a branch as a pen, and wrote and drew on the sand.

"This thing is called a musket, it can fire a projectile, it can take a person's life a hundred steps away, even if it is heavy armor, it is difficult to resist the defense, but unfortunately the casting process required is extremely high, and it is not possible to obtain it in a moment......"

"This thing is called artillery, it can shoot several pounds of solid iron bullets several miles away, regardless of people and horses, it is powder, and the process required is also very high, but it is slightly simpler than the musket......"

Ling Zhen, known as the first gunner of the Great Song Dynasty, seemed to have opened the door to a new world in front of him, and a new world slowly unfolded in front of him, his eyes followed the branches in Zou Run's hand, and he was fascinated by new things that could change the pattern of the entire world war.

Unconsciously, the red sun was falling in the west, the sunset was brilliant, Zou Run straightened up his stiff body, rubbed his sore waist, and said to Ling Zhen seriously:

"Today's words, out of my mouth, into my brother's ears, but do not let the third person know, the follow-up test, this valley will be a forbidden place to climb the clouds, without the permission of you and me, no one can enter and leave without permission. I will also bring in a team of soldiers and horses, and listen to my brother's moderation, and my brother must remember it. ”

"But please rest assured, this is the skill of the gods, the law does not pass on the six ears, and the Tao does not pass on the inhuman truth Ling Zhen is still saved, in the future, I should be careful, starting with gunpowder, slowly advancing, and the others don't care first, for the battle plan of the cottage water army, since the first batch development of new rockets and earth-shaking thunder!"

Talking to smart people is to save trouble, Ling Zhen is worthy of being a person who has been in the officialdom, once he meets the right master, his enthusiasm in all aspects is stimulated, and even the ability to "figure out the will" is not taught by himself, and he can even draw inferences.

Zou Run was relieved and arched his hand towards Ling Zhen and said:

"In this way, everything will be left to my brother."
