Su Shi: "Do you know whether you are good or not?" ”

You Shi: "Yes." ”

Su: "Falsehood, hypocrisy, stealing, bullying, is this good or bad?" ”

You Shi: "Self is not good. ”

Su Shi: "However, if a general defeats the Qin people and bullies the Qin soldiers, is this not good?" ”

You Shi: "No, this is good." ”

Su Shi: "If there is a general who deceives the Qin people and sends his soldiers to steal the grain and straw of the Qin people, is this not good?" ”

You Shi: "No, this is good." ”

Su Shi: "In your words, falsehood, hypocrisy, theft, and bullying are not good, so why should they be good?" ”

You Shi: "My meaning, falsehood, hypocrisy, stealing, and bullying can be done to the Qin people, but not to relatives, friends, brothers, and Chu people. The Qin people are good, and the Chu people are not good. ”

Su: "Yes, I'll say it again. The Chu army was trapped in the Qin people such as the Changping Zhao army, the grain was cut off, the Qin base could not be attacked for a long time, the soldiers suffered many casualties, the army had no morale, and the soldiers had no fighting spirit. The general deceived and said: "The news has arrived, the Yingshi is thirty miles away, and the prince is in charge." King's order: Attack the right of the Qin people in early food, flank it, and win this battle! Then the whole army was greatly stirred up, and they came out of the siege with a single drum. Is this good or not? ”

You Shi: "This should be good. ”

Su Shi: "A boy in Yingdu was sick and avoided medical treatment, crying and saying: 'I have no disease, I have no disease'." His father deceived him and said: 'Medicine is really sweet'. He was cured and died, was his father's behavior not good? ”

You Shi: "This is good. ”

Su Shi: "There is a husband in the north city of Daliang, who has no house so he does not marry, he is sad, he wants to subdue his sword, and his friends steal his sword." Isn't this good? ”

You Shi: "This is good. ”

Su Shi: "Jun once said: 'Falsehood, hypocrisy, stealing, and bullying the Qin people are okay, but not relatives, friends, brothers, and Chu people.'" The Qin people are good, and the Chu people are not good. 'Today's cases are all in relatives and friends, brothers, and Chu people, how can you be good? ”

You Shi: "Whew! I don't know what is good and what is not. ”

For Ganro and Meng Yi, the journey to a country outside of Kyushu was an extremely arduous journey, especially through desert areas. As a result of the sandstorm, half of the mission died due to lack of water. Fortunately, relying on the intermittent oases and large and small cities in the desert, it took them two years to cross the green mountains and reach Bactria west of the Kunlun Mountains.

Just as Aristotle IV wrote "Journey to the East", Ganro was also documenting his westward journeys along the way, especially the coup d'état last night. The original king had no interest in selling Ryoma, but now that he has a new king, maybe things will take a turn for the better.

However, there are two insurmountable problems in any transit mission: first: the two sides must communicate through two Rong interpreters; Second, from Xianyang through Longyou County of Di Daoyi (now Lintao County, Gansu Province), that is, the westernmost point of the Great Wall of Qin, it will take 10,000 li to Bactria, and it will take two years each way.

"Shangqing, Bai Di people are visiting." Meng Yi's message came from outside the house.

"Bai Di people are visiting?" Gan Luo quickly put away the pen and ink and Chu paper, although Qin and Chu had banned the purchase of Chu paper after the Qin and Chu conflicts, but Gan Luo still brought a lot. "Hurry up."

He said as he stepped into the atrium. Unlike the atrium of the Chinese world, the atrium of Greek architecture is actually a garden in the middle of a house, and the garden must be connected to the house on one side by a stone colonnade, and in the garden is a pool of flowers and water, and some fish are kept in the pool.

Gan Luo and Meng Yi beside him walked along the gate facing the garden, and saw an old Greek man with a high forehead walking towards him, surrounded by servants, and after crossing the pool, the old man stopped, and bowed to himself with his hands folded in front of him. Gan Luo had a bang in his head, and only waited for Meng Yi's whispered reminder that he solemnly returned the salute to this person.

As if in a dream, it seemed that overnight the Armaments Division had an innumerable amount of gunpowder at the disposal of the artillery. At the same time, a new, larger and longer cannon was also produced by Jutiefu.

At this time, the secret of gunpowder was well known, and the various departments of the Great Sima Mansion gradually learned that the Great King had made a new weapon that could rival the power of thunder. However, there are still many controversies about the use of this new weapon.

The first is that it is somewhere between a trebuchet and a ballista, making it a meatless and discarded weapon. However, when the artillery was charged four times and fired the shells 1,200 meters away, the artillery suddenly disappeared without a trace.

Of course, more than 1,200 meters is not an effective range, and the effective range is less than half of the farthest range, only a few dozen steps farther than a trebuchet, but this is enough. Although the trebuchet fires a hundred kilograms of stone projectiles, the trebuchet is difficult to move and cannot fight in the field; Although the crossbow can also fire stone projectiles of about five kilograms, it cannot throw stone projectiles more than a thousand meters away.

Artillery has become the best weapon to replace trebuchets and crossbows, and when to install them has gradually become a menstrual topic in the Great Sima Mansion. It's just that before the discussion of the Great Sima Mansion was finished, the king had already ordered the Jutie Mansion to build more than 200 cannons, and it was unthinkable that these cannons were actually mounted on the sea boat.

In the late autumn, a newly launched Chaos-class gunboat was sailing on Shaobei, the autumn wind was blowing, and when the twelfth bell rang, the artillery captain Wu Kong, who was standing on the gun deck, ordered the soldiers to reload, and at this moment there were only four eighteen-pounder naval guns on the deck.

Artillery must be built with great care, especially since the artillery carriage of the Mariner is completely different from that of the Infantry Cannon. The Pawn Gun Carriage was a low, four-wheeled cart on which the guns were mounted, and the ropes on either side of the end of the cart were connected to the ship's bulwarks next to the opening of the gun door. The huge recoil caused by firing the shells will cause the gun mount to retreat rapidly, and the sea boat is not land, and the longest beam is only ten meters, and these ropes can control the distance between the rear seat of the gun mount within two meters.

The gun mount, the gun itself, and even the load-bearing capacity of the gun deck, the center of gravity of the gunboat, all of which determined that the cannon should not be reckless. This is also the reason why Xiong Jing did not choose a twenty-four-pounder naval gun. A 24-pounder naval gun weighs two tons, and this is just a calculation, but in fact, the weight of a 24-pounder cannon often reaches two and a half tons, and with the addition of more than 400 kilograms of artillery carriages, its weight is already close to three tons. A sixth-class frigate with a draft of 5 or 600 tons is equipped with 24 18-pounder guns at most, and no matter how heavy the ship is, it will be unstable.

Although it is not in the sea, Xiong Jing standing on the deck of the stern can still feel the hull rise and fall with the waves, he likes this kind of ups and downs, but Xiang Yan and the others standing next to him don't seem to like this kind of ups and downs very much, which makes people dizzy.

"If you want to talk about cannons, you should talk about horses first. The general thinks that the infantry cannon can be saved? Xiong Jing wanted to laugh at this time, Xiang Yan was obviously red-eyed, the navy first had artillery, and then he was reluctant to be empty.

Kong's surname is also Mi, the witch. But this Wu clan ...... Ahem, women are in trouble with the country, when the king of Chuzhuang, Wu Chen was puzzled by Xia Ji's beauty, and he eloped with Xia Ji to the Jin Kingdom. Therefore it is ashamed to mention one's name to others, and to say only one's name to others. Wu Kong went from a crossbow to a trebuchet to an artillery, although the principle of firing weapons was different, but he was extremely skillful in using it. Xiang Yan originally had high hopes for Wukong to form the first infantry artillery unit, but he didn't expect that he was transferred to the sea boat by Xiong Jing.

"I think it's six horses." E Zhuo replied, "The total weight of the infantry cannon is 1,800 ......."

"Wrong!" The 12-pounder gun body was easy to build, but it took nearly three years for the gun carriage to be reluctantly finalized, and in the end, the weight of the 12-pounder gun was 1,830 kilograms. "Quadruple charge, the barrel of the gun has been thickened, and the weight of the ranks has exceeded 1,900 kilograms."

"That's it, you can also pull it with six horses." E Zhuo was stunned by Xiong Jing's 'mistake', as the director of the transportation department, he knew that the six-horse pull could pull multiple cars.

"How many stones can a six-horse cart fit on the grass?" Xiong Jing knew that E Zhuo didn't realize his mistake, so he had to ask a different question and talked about the Xianyang surprise attack that he had been planning. According to the plan, the cavalry of the four kingdoms would make a detour from the steppe to Yanshi Sai, and finally attack the Qin state, and the supply of the cavalry would be carried by accompanying four-wheeled carriages.

"Walking in the meadow, meadow ......" Ezhuo originally estimated that the four-wheeled carriage pulled by six horses could be loaded with a little five tons, but in fact, one five tons and six horses began to lose weight not long after, this is still a horse, if replaced by a smaller Di Ma, the situation will be even worse.

"How many horses does the king think the infantry cannon will take?" With red ears and red ears, Xiang Yan had to speak out to save the scene.

"Eight horses necessary." Xiong Jing's answer made him, Xiang Yan was slightly surprised. "The dragon horse can be reduced to six."

A few years ago, because of the publication of a certain history of field artillery, someone proposed that one horse could only tow 160 kilograms, and that the gun cart could only tow three horses and six horses, and that there were too many to use it, so he had a deep memory of artillery horses. A horse's normal pull is between 12 and 15 percent of its body weight, and the smaller the horse, such as the Mongolian horse, the higher the percentage. This is a normal pull, and in extreme cases it can reach or even exceed half of the horse's body weight.

The pulling force is like this, and the pulling weight is the towing weight multiplied by the drag coefficient. This is not only related to road conditions, but also related to wheels and bearings. Although Chu Guo had roller bearings, there were no rubber wheels, and the drag coefficient of any dirt road was more than 0.1, and many times the drag coefficient exceeded 0.15, close to 0.2.

That is to say, a horse weighing 300 kilograms, under normal pulling force, can only reach at least 225 kilograms, which is 250 kilograms normally. Twelve pounds weighing 1,900 kilograms in the ranks must be towed by four horses and eight horses, while a four-wheeled carriage towed by six horses cannot be carried by more than 1,800 kilograms because the coefficient of resistance on the grass reaches 0.15, and the weight that can be towed by six horses on the grass is 1,300 kilograms at most, minus the carriage of 500 kilograms.

Of course, Xiang Yan didn't know the scientific summary of later generations, and when he heard that Xiong Jing was going to use the precious dragon horse to drag the cannon, he shook his head again and again: "I'd rather have eight horses than a dragon horse." ”
