Just as the people of Hongshan were busy with the joy of building their first home, an incident that shocked the northern continent spread throughout the mountains. On June 20, the Jiangting of the Huang Yao Empire fell, and the Blue Horse broke history again and confronted the Huang Yao people across the river in the Tibetan Shengjiang.

On the 21st, the 7th Infantry Brigade of the Blue Horse marched into Huang Yao and attacked Yahai, and at the same time announced to the world that due to the Huang Yao Empire's rampant conquest, the people under its jurisdiction were displaced, and the Blue Horse officially declared war on Huang Yao in the name of the free male god to liberate the people of Huang Yao from fire and water.

and transferred the West Sea Cavalry Group to assemble at Huang Yao Feishui.

On the 22nd, Huang Yongshi, the king of the Huang Yao Empire, issued a statement to the Northern Continent, angrily accusing the Blue Horse people of treachery, and while making a treaty with them, they made a large-scale war against the empire. And called on the military and civilians of the whole country, regardless of the old and the young, the land is not divided into the north and the south, and it is my Huang Yao's duty to defend the land and resist the war. On the same day, Huang Yonglie, the marshal of the Imperial Huang Biao Army, was appointed as the commander-in-chief of the Varan Army, and the Imperial Zhengyipin led Kuang Yuanhai, the Minister of Defense, as the counselor of the army, and at the same time, the Tiger Guard Army in Dongshupo Province assembled at the Yahai headquarters. The Dragon Guard Army, the Huangxi Group Army, and the Beijing Guard, totaling more than 300,000 troops, gathered to the Tibetan Shengjiang.

Huang Yao Empire's Bitter Holy City Protector Mansion, Huang Lingshou watched the back of Situ Jian leave disappear at the door of the hall, and slammed the buckets, official letters, and snuff bottles on 、、、、the table with both hands.

Situ Jian is the chief official in charge of negotiating with the Blue Horse, and the official worships the left minister of the empire, and is a country-level Zhengyipin. The Blue Horse people sang a double reed to the Huang Yao people in Luoshui and the Crazy Dragon Cave, and the Jiang Pavilion was lost. Situ Jian means that he wants the empire to pass through the Wind and Snow Empire northwest of the Blue Horse and conduct peace talks again. Although the reason is not explicitly stated, even a fool can hear it. First, if Huang Yao and Blue Horse go to war, they will inevitably reuse Huang Yonglie, the first marshal of the empire, and Huang Yonglie has always had political views with him. It is difficult to ensure that Huang Yonglie became more powerful after the reuse, and interfered with the national policy of focusing on grain that he promoted. Second, the empire is the granary of the Northern Continent, and even the most powerful wind and snow empire in the Northern Continent also relies on the empire to supply thirty percent of its grain. In the two provinces of Huangdong and Huangxi, almost all the grain merchants of the northern continent were stationed. Separated from the Tibetan Shengjiang, let's not talk about whether the Blue Horse people can fight, even if they fight, such a complex international relationship is enough for the Blue Horse people to have a headache. He believes that this is the best time for the Empire to negotiate peace with the Blue Horse. This time, he was willing to wrestle with the team and personally go to the Crazy Dragon Cave to negotiate with the Blue Horse Man.

"Lord Wang!" Hearing the sound of the utensils in the hall being overturned, the guard Muhu asked.

"I'm fine!" The voice was deep.

The Blue Horse army pressed the border, the Wuzun monster Liu Napo disappeared, and there was a civil uprising in the south, and there was a deficit in the treasury for the first time in many years. For the first time, he was suspicious of the policy of rejuvenating the country with grain, which he was proud of. At present, the country's grain output is increasing, but the national strength has not increased but has declined, and the fiscal deficit is even more incredible.

Huang Yao is located in the center of the northern continent, bordering many countries, and the increasing grain production has not allowed Huang Yao people to get rid of poverty, but has provoked the surrounding countries to eye.

Isn't that wrong? What's wrong? Is it really what the man said more than ten years ago?

Red Mountain, people have begun to gradually forget, that day of the ghost fire, the dog still looks the same as before, meditating, practicing the brain, but the fire is not like from time to time to visit the new cave that everyone helped him play. The new cave is not much bigger than the previous one, and the biggest difference is that it is now inside and outside, which also fully proves that the hole-making technology of the people of Hongshan has indeed improved.

These days, when the dog is alone, he is thinking about Phantom Xiao, so he also went to Yu Wenhua to ask for a lot of bows and arrows, crossbow machines to study. His idea was simple, to use the explosive effect of the Phantom Shaw on a crossbow or a bow.

After a few days, he figured it out. Phantom Xiao will not be vaporized when soaked in ordinary water, only when it is soaked and absorbs the water that emits gas after absorbing the burning of Phantom Xiao, it can be successfully vaporized, this gas is very stable in the air, and it will explode when it encounters fire.

As for how to combine it with bows and arrows and crossbow machines, it was a piece of cake for him, a mechanical expert in his previous life. He has n ways to combine them, considering the current industrial level of the mainland and the degree of acceptability, he decided to do something more primitive, and the power should not be too prominent in the current military category.

Therefore, his practice is to use the bamboo in the red mountain as a vessel for gas, take the bamboo into small sections, set up a gas hole in front, and inject the vaporized phantom Xiao from the front air hole, and before injecting, set a trigger device at the back end of the bamboo joint. For this trigger device, he used a kind of stone on this continent, called the Star Stone, which is a bit like the flint in the previous life, this kind of stone can burn for a long time when it encounters friction. When the crossbow flies in the air, the two star stones on the trigger device will burn through friction, and there is a temperature insulation layer in the middle, when the crossbow shoots at the target, or falls freely, due to inertia, the bamboo will rush forward under the action of inertia, and the temperature insulation layer near the rear end of the bamboo is actually a destruction device. If the recoil is not large and the plug does not fly, then the rear end destruction device will instantly shatter the rear end of the bamboo under the action of inertia, releasing the vaporization phantom.

When the phantom was not installed, the dog did many experiments, such as the destruction device, the temperature insulation layer, the inertial top opening race, etc., all of which were perfected while experimenting, and after dozens of adjustments. I feel that all links and parameters are basically consistent with the blasting conditions.

Because the crossbow machine was too cumbersome, it was quite reluctant for him to be dragged to a deserted place two miles away by a small homemade trailer, so he only did one live-fire experiment.

In order to master the burning characteristics of the phantom Xiao, the dog carried out countless burning experiments over and over again, and he found that the burning and blasting of the Phantom Xiao were basically the same as the ** in the previous life, but it was much more violent than **.

So the dog combined the range of the propulsion bow with the phantom shot. In terms of theory, for him, a mechanical designer from the earth, it is not difficult to talk about, and the principle is basically that the gasified phantom Xiao and the non-gasified phantom Xiao are matched together in proportion, so that he does not explode when burning, but it must be violent, and the thrust can be generated by violent, and the combustion of ordinary phantom Xiao will not produce thrust at all, which is easy to say, but it is not the same thing to do.

After hundreds of combustion experiments, the dog gradually mastered the ratio of vaporized phantom and phantom Xiao. It took an unknown number of experiments to roughly calculate the critical point at which the phantom burns most effectively without causing an explosion.

Next, what makes the dog a headache is the ignition, how to light the fire?

When is the ignition? A lot of research has been done, but it is not too ideal, after all, the industrial base of this continent is placed there.

After a few moments of chance, the dog looked at the ordinary phantom Xiao that burned out, and suddenly had an inspiration! Yes, there is also a unit time for phantom burning, and then the dog carried out hundreds or thousands of phantom burning calculations. Initially mastered the thickness required for 3 seconds of phantom burning.

The bows and arrows used by the garrison now basically reach the exhaustion stage after 3 seconds of firing. When an arrow is launched, there are about three speeds from leaving the Xuan to falling freely, and the fastest time is when it is just off the string, at this time, the force of the arrow breaking through the air is the largest, and the arrow breaking through the air is greater than the resistance of the air, and the arrow will fly faster and faster. The second stage is the holding stage, that is, after the arrow flies in the air for a period of time, the air resistance is equal to the arrow's air breaking force, the arrow flies at a constant speed by inertia, that is, the maximum effective range of the bow and arrow, and the last stage is the attenuation stage of the arrow, the air breaking force of the bow and arrow is less than the air resistance, at this time the flight speed of the bow and arrow will be slower and slower, the lethality of the bow and arrow is very effective, and if people pay attention, it will hardly cause any harm to man.

After analysis, the dog feels that it is most ideal to accelerate when the arrow enters the stage of stalemate and stability, first, the recoil generated by the burning of the phantom Xiao will not be contrary to the power of the arrow, thus affecting the speed, and second, because the arrow flies relatively smoothly, the impact of acceleration on the target hit at this time is relatively small.

When the arrow enters the constant state, it takes about 3 seconds, of course, the decay speed of different bows and arrows is different.

The last is the ignition device, the same is the use of star stones, two star stones that can collide with each other, when the arrow leaves the bowstring, the star stone will burn because of the collision, thus igniting the ordinary phantom Xiao, the thickness of the phantom Xiao is calculated, and after the burning, it will also ignite the gasification phantom Xiao and the ordinary phantom Xiao in the bamboo joint. In the narrow bamboo joint, the fierce burning creates thrust, and the bow and arrow can extend the range of the arrow.

Looking at the bamboo knots of different sizes that he had made, the dog was a little relieved. This is his hard work for more than ten days. If it weren't for my good memory, I wouldn't have been able to do it in such a short time. This is still backed by the 5,000-year-old civilization of the earth in his previous life.

Let's not talk about whether the mainland's industrial level can think of this step in terms of understanding and understanding of trigger weapons, just the accumulation of thousands of experiments, there is no super memory, that is,, there is no computer here.

In Liu Qingshan's tent, everyone listened to the dog's dictation. "Scud No. 2 can accelerate the grass bow for 4 breaths of 300 meters, the effective range is 550 meters, and the general arm strength landing time is 8 breaths!" "Scud 3、、、、" "Wait! You wait! How many meters is the effective range of this leg? "The fire is like interrupting the dog's speech.

Pull! You just pull it out desperately! Tie Magnolia didn't squeak, muttering in her heart. "Haha! Hehe" Yu Wenhua almost burst his belly with laughter, and bent down to hold his belly. "Dogs! And adults are no joke! "Hair reminds.

Su Ping secretly glanced at Liu Qingshan.

Liu Qingshan was also blindsided and looked at the dog.

Feng Zhanyun wanted to touch the large and small bamboo knots with his hands. "Don't move" the dog reminded nervously.

Feng Zhanyun was startled by the dog's shouting and was about to have a seizure. "He told you not to move, not to move!" Tie Yulan also hurriedly reminded that she didn't believe what the dog said about flying leg No. 2, she was worried about the ghost fire of the orchid that day. If the ghost fire of the day really came out of this, not only the wind and clouds, but also the people of this tent would have confessed.

Feng Zhanyun looked at the dog, then at Tie Yulan, and finally retracted his hand. "Quick! Tell you Grandpa Fire how much range this leg can extend the bow and arrow? "By the way, I took a sip of tea." 300 meters," the dog said dryly. "Poof"

Liu Shan's face was full of tea, and he looked innocently at Huo Wuxiang. "Coax"

The people in the tent couldn't help but laugh.

The dog looks at this and then at that. "Oops! Laugh at me" "Dog! This is the big tent of the Chinese army, not only you and me, no jokes," Liu Qingshan suppressed a smile and said seriously. "Head! I'm not kidding" "、、、、、、、、" "Can you try arrows!? The dog reminded.

On the Red Mountain Exercise Ground, there were a number of generals in the garrison, surrounded by refugees and soldiers.

Stained with the arrow on the handle, hung up what to fly No. 2, aimed at the arrow target 500 meters away. "Dogs! Mo's joke Ao! He looked at the dog not far away worriedly. Brother Mao, it's okay! Shoot! Oh, yes, it might be a little unaccurate! "The dog looks like an adult.

Dipping hair turned his head, held his breath, looked at the mountain, opened the bow, pulled full, pulled again, pulled again, and could no longer open 、、、、、 "spray ~~~~~~ eat~~" and "suck" the sound of collective gasp.

The fire is like a mouth that opens into an O.

Feng Zhanyun's eyes widened.

、、、、、、、、、、、、

There was silence all around, and the picture seemed to be frozen at the moment when the arrow penetrated the target.

It took a while for everyone to come back from the shock. What is the concept of a bow that can shoot a bow and arrow at the distance of a crossbow machine? "Dogs! Are those guys so powerful? "How far can this shoot?" Dog, I said this is the biggest? "Dog! How far is this minimal? Can be used on my little horn bow, right? "Dog! In the past two days, I can lend you a lot of bows and arrows, crossbow machines, and "dogs!" 、、、、、、、“

The eyes of the crowd as they looked at the dog became fiery and green.

Ding Hai pulled the crossbow machine spring away without using his feet, filled in the crossbow arrow, and hung the dog's What Fei No. 1, "Shoot it?" "Look at the dogs." Shoot! Quick shot "Tie Magnolia is impatient. "Whoosh" "Buzz"

Refugees and soldiers who were busy in the distance crawled down en masse when they heard the noise.

500 meters away, on the exercise ground, a two-meter-high and two-meter-wide dark blue flame was burning.

Except for the dogs, everyone else is collectively petrified.

It has been two days since the arrow test on the military field, and the dog cave has not broken in the past two days. "Dogs! The name No. 1 is too long to remember, so let's call him a dog cannon in the future! "Ding Hai flattered the dog and renamed Scud No. 1." Dog run! It's a shame that you want to come out! Dipping hair jumped, perhaps inspired by Ding Hai. Stained hair also renamed what to fly to No. 1. "Dogs! Why don't you call it a Yang cannon! "Yang (Yang) cannon!" The dog has a picture of appetite.

Seeing that the dog was happy, Ding Hai continued, the No. 2, No. 3, No. 4 were called "Yang (Yang) gun is good!" “
