Yuwen Wen made a gambling contract with Xu Shao, the son of Yuezhou Thorn History, outside the Shili Pavilion, and then came to Yuezhou Prefecture to govern Xiaochang City, stayed overnight, and set off the next day to return to Anlu at noon.

When the servants returned home, Yuwenwen found that the atmosphere in the house was a little weird, and the servants were as frightened as if they had seen a ghost, Li Sanjiu, who is now a housekeeper, and Lin Youdi, his right-hand man, and other four abacus beads all looked at him with admiration on their faces, and the actress Liu Caiyun gloated and squeezed her eyebrows, and her husband, Zhang Dingfa, the head of the hospital, gave him a thumbs up in private.

His wife Wei Chi Chi Fan has been looking at him in a daze, his eyes are slightly red as if there are tears, and he looks like he wants to cry but can't help crying, Yu Wenwen is cramped and restless to bathe and change clothes, just after lunch, he was pulled into the room by his wife, and saw that the servants outside the door were scattered like birds and beasts.

Yuwen Wen was overjoyed and ready to 'boot up' and do a big job, but he didn't expect to eat a shot in the back of his pig teammate.

The pig teammate is Wei Chi Chifan, opened her cherry mouth and bit her husband's arm, the sharp pain made Yu Wenwen gasp, but he could only endure it, now it was his beloved wife who bit him, he couldn't kick it away.

Yu Chi Chifan bit his arm and didn't let go, then his shoulders twitched and cried, big tears wet his sleeves, Yuwen Wen panicked when he saw this, and hurriedly took his wife in his arms to comfort her, she was already crying silently, but she couldn't stop beating her husband's chest with a powder fist.

The second monk of Yuwen Wen was puzzled, and recalled the expressions of everyone in the Fang Cai Mansion and suddenly realized: The soul is faint, someone has leaked the news!

After the surprise attack on Huangcheng that day, Yu Wenwen ignored his father's opposition and simply 'took over' the task, and the next day he went to Beijiang Prefecture in the north of Huangcheng to govern Lu Guancheng to brush up on the copy of "Into the Tiger's Den to Get the Tiger", so he was fully prepared to seize the power without danger, and afterwards he ordered his entourage Yuwen Fifteen to keep the secret and not let his wife know.

Dare to betray me! Lao Tzu wants you to live, not death, can't!

Even if he is full of anger now, the top priority is to coax his wife, and he has lost countless dollars to stop crying, and he heard Wei Chi sobbing and said that the truth was really his "entering the tiger's den", but it was his brother Yu Wenming who asked his wife Li to tell him, and it seems that the source is from his father.

"You promised me to take care! Why, why should I do if you have a three-long and two-short! ”

"I won't dare to do it next time."

"You lied to me!"

"Listen to me, this stage is the rising period of my career" Yu Wenwen couldn't help but play a stalk.

The mouth was about to be coaxed, and the little couple talked about what they had experienced in the past few days, and when they heard Yu Wenwen say about the 'big adventure' of seizing Huangcheng and Luguancheng, she was so distressed that she almost shed tears.

The atmosphere between the ears and temples gradually became ambiguous, Yu Wenwen kissed his wife's hand and was uneasy, Yu Chi Chifan's whole body was weak and struggled and said: "Erlang is still in the daytime, you can't declare it in the daytime."

Yuwen Wen, who was bitten and full of evil fire in his stomach, forced the bow to forcibly unlock the 'new posture' and consolidated it repeatedly, and the little couple tossed for most of the day before it stopped, and even sent dinner to the room with a red face.

At night, Yu Wenwen was lying on the side of the desk with his clothes draped, drawing things on the white paper with the light, and Yu Chi Chifan hugged her husband from behind, leaning her chin on her husband's shoulder and looking curiously at the strange figure in front of her.

"What are these?"

"Hmph, the towed three-bow winch crossbow of the Eight Bull Force!"

"What about that?"

"A long-range gravity projectile cannon that spans the ages!"

Early in the morning of the second day, Yu Wenwen got up and covered his wife's long legs, and after finishing grooming, he rushed to the governor's mansion with the sketches.

He wanted to make equipment that had not yet appeared in this era, but there was no difference in the manufacturing process, the so-called principle was that a piece of window paper would be broken at a point, and as long as the craftsmen had seen the real thing and analyzed it carefully, they could paint the cat and the tiger.

It's still the old way, first make a small scale model so that the craftsmen have a perceptual understanding, and then enlarge it after they are familiar with the basic structure, as for how to get the full-size object, these skilled craftsmen have a headache.

For reasons of secrecy, Yu Wenwen selected two groups of capable craftsmen, and asked the chief steward Shi Du Shijun for an idle barracks in a remote area outside the city, and then moved to the barracks with materials and tools, and there were soldiers outside to prevent idlers from approaching.

The craftsman can go home to rest every night, but things can't be taken out of the barracks, and he also slaps his swollen face and fills the fat man and sends the craftsman half a penny to each person as 'overtime pay', and he uses both soft and hard words:

"If someone asks you what you're making, tell him it's a powerful anti-heaven artifact."

"How powerful is it? A shot eroded for dozens of miles, and a cannon passed by a landslide and the ground cracked! ”

"Too exaggerated? No, no, no, it's just to say that, remember to say it, say important things three times! ”

"If anyone dares to talk nonsense, my father will send a strong man to greet his daughter!"

In ancient times, the power of many ordnance was exaggerated, for example, the literati in the late Ming Dynasty touted the artillery is what "erosion for dozens of miles" is really outrageous, Yuwenwen thinks that the measures of secrecy are better than sparse, if someone asks, simply add oil and vinegar to the sky, so that others will not believe it.

There are some things that you are more interested in the more you cover others, but you are open and honest, and then nine out of ten sentences are false, which can effectively hide the real information, as for the appearance, it is better to keep it as secret as possible, and it will be too late for the enemy to see the real face for the first time.

It took two days for the small-scale technical verification models of the "Eight Bull Power Towed Three-in-One Winch Crossbow" and "Cross-Era Long Range Gravity Projectile Cannon" to finally appear in front of Yuwen Wen and craftsmen.

"Very good, you guys have worked hard, the next thing is to zoom in like this." Yu Wenwen roughly described the size and size of the real thing to the two groups of craftsmen, and when he saw everyone nodding, he clapped his hands and asked Lin Youdi to serve a plate of copper coins.

"One person and a half hanging, all give their own hearts to the father, it's still the old rule, if anyone leaks the news"

"The county prince sent a strong man to greet his daughter!" All the craftsmen shouted in unison.

Yu Wenwen nodded with satisfaction and let the craftsmen who were smiling with the money start work, and called the two groups of leading craftsmen to come over:

"There are two drawings here, the old rule, first make the model according to the drawings."

The two leading craftsmen took the drawings over and carefully studied them, and after a few days of cooperation, they adapted to the painting style of Xiyang Jungong a lot, and after reading it, they almost had a number in their hearts: "Jungong, I don't know what to call these two things?" ”

"Far West Rome twists the power straight at the ballista."

"The medicine of Brownian motion is a monkey."

As a pseudo-military fan, Yu Wenwen has a bad taste for weapon naming as always, and it is impossible for anyone to understand what he is saying in this era.

"Eight Bull Force's Towed Three-Bow Winch Crossbow" is a three-bow bed crossbow in the Northern Song Dynasty, also known as the 'Eight Bull Crossbow', which once relied on 'faith' to hit and kill the Liao army's chief general Xiao Tzu Rin in the Battle of Tanyuan.

"Cross-era long-range gravity projectile cannon" is a gravity catapult that made a strong effort for the Yuan army to break through Xiangyang in the late Southern Song Dynasty, also known as "return cannon". Both of these weapons have appeared on the ancient battlefield, and in principle, they are very simple and much easier to make than artillery, and Yuwen Wen just wants them to come out in advance.

As for the latter two, I don't know if they can succeed, so let the craftsmen try to drum and see.

I paid for it!

"Master Lang, if you spend a lot of money like water, Sister Liu will scold." Lin Youdi looked at Yu Wenwen with a sad face, after coming to Anlu, Liu Caiyun was responsible for 'generating income', and it was easy to use "glass beads" from the local tyrant to subsidize the family.

Yuwenwen patted him on the shoulder and said that he would explain that he didn't have to worry when he went back, but his heart was also dripping blood:

The soul is light, how to challenge the big boss Yang Jian without spending money to buy plug-ins!

The family is already on the right track, his wife Wei Chi Chifan is in charge of housekeeping and management in an orderly manner, Li Sanjiu is the housekeeper and servant, Liu Caiyun is responsible for the cottage small workshop to engage in some 'fake and shoddy' income generation, Zhang Dingfa is the head of the nursing home, Lin Youdi is the 'experimental supervisor', and he can only prepare desperately.

The 'Powerful Elephant Two-Year Trial Aerodynamic Lianzhu Gun' has made some progress under Lin Youdi's persistent experiments, and this thing can now kill mice within ten meters, but it is still far from being used for self-defense.

With his wife as a strong backing, Yuwen Wen ran to the barracks outside the city every day, mixing with the craftsmen and tossing 'plug-ins', and it was late May in the blink of an eye.

In the morning, Yu Wenliang, the governor of Anzhou, and his two sons appeared in the special barracks outside the city.

"This is what eight, what three-bow, what crossbow?" Yu Wenliang touched his chin beard and looked at a strange giant crossbow in front of him, the crossbow bed was equipped with three large bows, the first two were straight and the latter was reversed, the winding mechanism was the winch on both sides, and the two wheels under the crossbow bed seemed to be able to be dragged by horses.

"It's a three-bow bed crossbow." Yu Wenwen waved his hand after replenishing, and the soldiers standing next to the three-bow bed crossbow began to work, sixteen people pulled the left and right winches in two groups to wind the giant crossbow, and the tense creaking sound of the bowstring made people feel hairy all over the body.

After the winding, a soldier walked over with a huge long arrow, and looked at the long arrow Yu Wenliang's hand touching the beard under the chin and couldn't help but stop:

The iron arrow wooden shaft has an iron tail, where is this arrow, it is clearly a spear-like giant arrow!

The long arrow was put on the arrow road, and a strong soldier came to the three-bow bed crossbow with a wooden mallet, and after Yuwen Wenwen signaled, he suddenly swung the mallet and smashed it down on the trigger, only to hear the sound of "boom, boom", and the long arrow flew out, piercing the earthen wall in the distance, stirring up a puff of smoke.

Yu Wenliang and Yu Wenming looked at the long arrow on the earthen wall in the distance and were dumbfounded, and it took a long time to remember to ask how far it was.

"About 400 steps, 600 meters." Yu Wenwen has tried many times before, and he already has a bottom in his heart, "If you improve it again, you can go up at least six hundred steps." ”

"......" The two fathers and sons didn't know what to say, if this thing hit someone

"And this." Yu Wenwen decided to strike while the iron was hot, and took his father and brother to the other side, where a huge device was erected, Yu Wenliang had led the troops for many years, but at a glance he could see that this thing was very similar to a catapult.

It's just that the catapults used for siege are all pulled by manpower, and there are many long hemp ropes tied to the lower end of the cannon for people to pull, but now there is a huge wooden box hanging at the lower end of the cannon of the much larger catapult in front of me.

And this catapult is too big! The height of the stand alone is not less than eight meters, and the stone that is ready to be thrown, is the stone wrong!

Yu Wenliang looked at the stone that had been put into the cannon's cloth pocket and was stunned, this stone looked like it was fifty or sixty pounds, but he had never heard of any catapult that could throw such a heavy thing.

"Artillery cannon!" With Yu Wenwen's order, the operator pulled down the mechanism, and then the wooden box at the lower end of the cannon sinked suddenly, and the wooden frame made a creaking sound, and at the same time, the thick cannon suddenly waved and threw out the big stone in the cloth pocket.

There was a burst of dust on the flat ground in the distance, which was the smoke effect caused by the boulder hitting the ground, and Yu Wenliang and Yu Wenming were stunned as they looked at the dust that rose.

"How far?"

"Nearly two hundred steps, that is, about three hundred meters."

"How much does it weigh?"

"Sixty pounds."

The father and son gasped, Yu Wenming was okay, he was purely frightened by the operation of this huge machine, and as a veteran of the battle, Yu Wenliang knew what this thing meant.

Two hundred paces, which means that you can throw stones out of range of most defending archers; Sixty pounds, which of the ordinary city walls can stand it if it is smashed like this!

"Father!" Yu Wenwen solemnly looked at Yu Wenliang and said: "These two kinds of equipment craftsmen are already familiar with, and larger ones can be made, and a large number of them are not a problem." ”

"Mass production!" Yu Wenliang almost ripped off his beard, and he couldn't help muttering: "Bigger, more, if you smash it day and night, even the walls of Chang'an City won't be able to withstand it for long!" ”

Yu Wenming also came back to his senses, although he didn't lead his troops to fight much, he saw it thoroughly: "This cannon is the best for siege cities, but the three crossbows take too long to wind, and I'm afraid it's not easy to use in field battles." ”

Even if it is an archer with a fast rate of fire, when the two armies face each other, the opposing cavalry rushes to the front and shoots only three rounds of arrows, and this giant crossbow is ready for the first shot, and then the second shot is afraid that the opponent's cavalry has rushed to the front, of course, it is a sharp weapon to defend the city.

"The method of fast winding has a way to deal with it, and my son has never led troops, but he also has some ideas."

Yu Wenwen told his thoughts, now the cavalry on the battlefield is king, thousands of cavalry impact is unstoppable, can exclude all kinds of raids, ambushes, encounters, siege battles, the main force of the two armies to start a decisive battle is basically to infantry phalanx in the center of the core, cavalry flanks outflank.

The infantry on both sides engaged the enemy head-on under the cover of the archers, and the cavalry protected the flank reserves on standby, and after using various tactical means to make the opponent's formation unstable or demoralized, the cavalry outflanked the enemy and caused the opponent to collapse.

The biggest gain of cavalry combat is not before the battle, but after the defeat of the opponent, the infantry phalanx in the middle is like an anvil and the cavalry on both sides is like a hammer, as long as the anvil can resist the opponent's main force, the cavalry from both sides outflank and strike the opponent violently.

Regarding Yu Wenwen's opinion, Yu Wenliang agreed, no commander would use cavalry to attack head-on when the opponent's infantry was in strict defense, that was to send him to death.

The reason why a famous general is a famous general is that he can capture fleeting fighters on the ever-changing battlefield, and use his elite cavalry to suddenly plunge into the opponent's soft underbelly and cause the opponent's chain to collapse, but what does this have to do with the three-bow bed crossbow?

"The war is about to start, and when the main forces of the two armies set up a large array to attack, the power of these three-bow bed crossbows may not have been seen by the other party." Yu Wenwen's eyes flickered, "The infantry formed a formation to protect the giant crossbow, and when the opposing infantry formed a formation approached, they used the giant crossbow to shoot, if my father is the enemy general, how should I respond?" ”

"The archers can't reach it, the infantry is advancing too slowly, and the cavalry can't rush our infantry in formation. Is it a refund? Is it a change of formation? ”

"Since ancient times, it is the most difficult for the enemy to retreat, and it is also very capable of changing formations in battle, if you drive the soldiers to brave the long arrows and bloody advance, I am afraid that the morale will be low or even mutiny."

"If the imperial court sends Wu Anjun, Huaiyin Hou, Champion Hou, Wuxiang Hou and other leading soldiers this time to have nothing to say, they can only be captured."

Yu Wenliang's eyes lit up when he thought about his son's words, Yu Wenming was also eager to try, and Yu Wenwen continued to strike while the iron was hot: "There are two more things here"

Wu Anjun, the Warring States people slaughtered Baiqi; Marquis of Huaiyin, Han Xin of the three heroes of the early Han Dynasty; Champion Hou, Huo Quai, who sealed the wolf Juxu; Wuxianghou, Zhuge Liang, who is wise and close to demons. Yang Jian, if you summon them, Lao Tzu won't play!
