After Li Hao returned to the ground, he took the crossbow blueprint of the bed and came to the Taiji Palace again, which was about the same time as yesterday, and it was also sunset.

Coincidentally, Li Shimin is having dinner again, which shows that Li Shimin's meal time is still very regular, this is not the point, the point is that Li Hao is here.

When he heard that Li Hao asked to see him, Li Shimin was stunned and said to himself blankly: "Why is this kid here again?" ”

Doubts are doubts, he still announced that he met Li Hao, after Li Hao entered the palace, he knelt down, Li Shimin put down his chopsticks and asked with a smile: "Poetry madness, didn't you come here to eat?" ”

Li Hao suddenly had a black line on his face, and said: "Back to Your Majesty, the sharp weapon of the country is offered, and it is a matter of social affairs, so I dare not slack off." ”

"Oh? A weapon of the nation? Li Shimin's eyes lit up when he heard this, and he hurriedly asked, "Where is the sharp weapon?" ”

Li Hao held the envelope high with both hands: "Your Majesty, the drawings are here." ”

"Present!"

Xu Lian hurriedly trotted down and presented the envelope, Li Shimin opened the wax seal, unfolded the drawing and looked at it...... I don't understand! Can he understand it, he is not a professional, at most he knows that this is a crossbow.

The car crossbow and the bed crossbow are actually about the same, in the Tang Dynasty it was called the car crossbow, and in the Song Dynasty it was called the bed crossbow, the car crossbow is much smaller than the bed crossbow, and the power is naturally not as big as the bed crossbow, however, there are wheels under the base of the car crossbow, and it is much more labor-saving to transport than the bed crossbow.

In fact, these two kinds of crossbows were born in response to the times, the Tang Dynasty was strong, attacking everywhere, and the easy-to-transport crossbow was naturally more suitable, and in the Song Dynasty, the emphasis was on literature and light on martial arts, not to mention what to attack, basically most of the time was defending the territory, and the Northern Song Dynasty was defended after the Southern Song Dynasty.

In fact, the army of the Song Dynasty still had some ability to defend the city, since they often defended the city, then the bulky and powerful bed crossbow came into being, and the car crossbow was gradually eliminated.

Li Hao...... What are you drawing...... Crossbows? Li Shimin asked Li Hao uncertainly.

Li Hao shook his head and said, "No, Your Majesty, this is a bed crossbow." Li Hao corrected.

Li Shimin looked at the drawings carefully, glared and said, "This is obviously a crossbow!" The little eyes seemed to say: "Don't lie to Lao Tzu, Lao Tzu has read books, read a lot of books!" ”

Li Hao said helplessly: "Your Majesty, its base is very similar to a car crossbow, but his crossbow body and crossbow arm are bed crossbows. ”

"Oh?" Li Shimin raised his eyebrows and looked at him, "What's the difference between the two?" ”

Li Hao said: "The bed crossbow is larger than the car crossbow, has a longer range, and is more powerful. ”

Li Shimin shook his head and said: "No, the crossbow is already very large, and it is extremely inconvenient to transport, if this crossbow is larger, not to mention the cost is more expensive, it is very inconvenient to transport it alone." ”

Li Hao said: "Your Majesty, although this bed crossbow is large, it can be disassembled, you carefully look at the decomposition diagram on the left, the crossbow arm and crossbow body are detachable, after dismantling, the base becomes a trolley wooden cart, which is much lighter than the crossbow, this is the method of breaking the whole into zero." ”

Hearing this, Li Shimin stared at the schematic diagram on the left for a while, and finally understood a little, narrowed his eyes and said, "It's a little interesting." ”

Li Hao continued: "Your Majesty, as we all know, the most expensive crossbow is the crossbow arm, and quite wasted man-hours, it is rumored that the crossbow arm of a car crossbow needs to take three months to make, that is no longer something that can be measured by money, however, there is no such problem with this bed crossbow, you see, the crossbow arm of this bed crossbow is three arms, two more arms than the car crossbow, since the quality of the crossbow arm is too high, then we will win by quantity, so that the cost does not rise but falls, and the working hours can be shortened from three months to two months. ”

"That's a great idea." Li Shimin praised a sentence and suddenly frowned, "It's just that if you really want to do it, I'm afraid it may not be feasible." ”

Li Hao said: "Your Majesty, why don't you let Weichen try it, this trial cost, you don't have to pay for it, Weichen himself will pay it, and it should be a modest contribution to Datang." ”

Li Shimin looked at him in surprise, and said for a long time: "Poet, why are you so generous today?" ”

Li Hao was embarrassed when he heard this, and blinked quickly: "Your Majesty, Weichen has always been very generous. ”

"Are you drunk without drinking, you start talking nonsense." Li Shimin scolded with a smile, "Okay, I won't keep you today, you go back, and report to me as soon as the bed crossbow is built." ”

"Obey the order, Weichen retires." Li Hao bowed and bowed and exited the Manna Palace.

As soon as he walked out of the main hall door, he saw a short figure walking towards this side one by one, followed by a eunuch and two palace maids, although he couldn't see his face, but from this short size and walking action, Li Hao could see at a glance that it was Li Mingda, the princess of Jinyang.

Li Mingda came to the front and saw that it was Li Hao, and his little face immediately bloomed, and he saluted very obediently: "My son has seen Mr. Li." ”

Li Hao returned the salute: "Meet Her Royal Highness Princess Jinyang." ”

Because it was the middle of winter, the night wind was colder at night, Li Mingda's little face was red from the cold, Li Hao squatted down and covered her cheeks with warm palms, and reproached: "Son, you are not well-behaved, did I tell you that you can't blow cold wind, you see, it's so cold, if you catch a cold, you will be sick again, and you will have to take a lot of medicine at that time." ”

Li Mingda suddenly seemed to have done something wrong, hung his little head and said, "Er'er knows it's wrong, Er'er just misses her father." ”

"Well, my son is really filial." Li Hao stroked her slightly yellow hair lovingly, and said, "But you can't run around in the cold in the future." ”

"Hmmm! Listen to Mr. Li Mingda nodded vigorously, looking at Li Hao with a pair of big eyes.

Li Hao was instantly cute, and secretly shouted in his heart: "Li Shimin, you must have saved the earth in your last life, and you are fortunate to get such a good daughter in this life." ”

Li Hao got up and said to the eunuch behind Li Mingda: "Princess, when the little princess goes out, you must pay attention to wind protection and keep warm, you don't have to think I'm verbose, if Your Highness has three long and two short, then you can only be unlucky." ”

The eunuch hurriedly said: "The lesson of the county man is that the little one must take care of the princess carefully, and even if the little one freezes to death, he will not dare to let the princess get cold." ”

Li Hao waved at Li Mingda: "Son, Mr. will go back first." ”

Li Mingda saluted him again: "Sir, go slowly." ”

Li Hao suddenly seemed to take her home as a daughter to raise, but he didn't dare, because then Li Shimin would ask for his head, so he could only smack his mouth helplessly, turn around and leave slowly.

After returning home, Li Hao specially vacated the empty room and asked Lu Zhi to take the craftsmen in to build a bed crossbow, anyway, this time it was ordered by the emperor, and he could make it openly.

The normal cost of a crossbow is generally about two thousand, Li Hao only gave Lu Zhi a budget of one thousand this time, this kind of sharp weapon is bound to be produced in large quantities, if the cost is too high, then it is not of much significance.

It's New Year again, Li Hao remembered that when he went out with the army to Tuyuhun during the New Year the year before last, last year's New Year, he was locked up in the prison of Dali Temple, this year he can finally spend a good New Year at home, he is a little excited, on the morning of Chinese New Year's Eve, Li Hao was in the study room preparing to write the Spring Festival, Qin Su was excited after listening to it, and volunteered to sharpen ink for him.

However, when Li Hao wrote a couplet, Qin Su's excitement was gone, he looked at the couplet with a worried face, and then asked Li Hao: "Childe, do you want to stick this couplet on the door?" ”

Li Hao blinked: "If you don't stick it on the door, will it stick to the ground?" ”

Qin Su suddenly felt so embarrassed, and wanted to remind him that the words were too ugly, and he was embarrassed to speak, but at this time, Turandot walked in, and when he saw the couplet on the table, he immediately took it in his hand and exclaimed: "My God, whose word is this, it's so ugly!" ”

Li Hao suddenly felt so embarrassed, and snatched it over: "What do you know, you are outside...... Girl outside the door, I guess I can't even write......"

"Who said I can't write!" Turandot suddenly became competitive when she heard this, walked behind the table and picked up the brush to spread out the paper, and wrote stroke by stroke, she didn't write quickly, but to be honest, the words were very good, at least much better than Li Hao's words.

Li Hao suddenly felt so embarrassed, and hurriedly said: "Ah, it's so fragrant, I'll go to the kitchen to see what good dishes Aunt Jin cooked today......

Qin Su covered his mouth and smiled when he saw this, Turandot saw her smiling, and asked with a blank face: "What are you laughing at, I don't write beautifully?" ”

"You're very well written." Qin Su said, "I'm a laughing boy, he has outstanding literary talent, but the words are written very ugly, you have just studied for half a year, and your words are much better than his." ”

Turandot was praised by her, and was very happy, and proposed: "Then let's write this year's Spring Festival couplets together." ”

"Okay." Qin Su nodded, and wrote the Spring Festival couplets with Turandot with a pen.

Due to the increase in the population of the family, this year's Chinese New Year's Eve dinner set two large round tables, which is happy, Li Hao is very happy, he has not been so happy for a long time, every time at this time, he thinks of his parents and brother in another world, he has not contacted his brother for several years, he really misses them.

Although Li Hao had something on his mind, he didn't show it, first sent a big red envelope to everyone, and then took everyone to play poker together, keeping the New Year, and the eleventh year of Zhenguan ended on this night.

On the first day of the Lunar New Year, Yuan Zhengri, Li Hao dressed neatly and went to Chang'an with an oxcart glass products, he was going to give gifts for the New Year, although he made a lot of money, but he was still reluctant to give too expensive gifts, glass products are the best choice, low cost, and face.

It stands to reason that Cheng Biting Jin has the best relationship with him, and he should be the first to go to Cheng Biting Jin's house, but Li Hao didn't, because he knows Cheng Biting Jin too well, his house is the Longtan Tiger's Den, can you still come out after entering, and the last one to go to his house.

However, the heavens did not fulfill people's wishes, when he was biting the door of Jin's house on the way, the door happened to open, and it happened that Cheng Biting Jin came out, the two glanced at each other, and they were stunned for a moment, Cheng Biting Jin suddenly shouted excitedly: "Stinky boy!" ”

Li Hao's hair stood up all over his body, and he whipped it hard on the cow's buttocks, shouting: "Run!" ”

The old bull was in pain, spread his four legs and ran lifelessly, and the car full of glass products was bumped and ping-pong.

"Stinky boy, run there!" Cheng Biting Jin shouted, just as his horse was sent out, he turned over and chased after the horse.

How could a cow outrun a horse, not to mention dragging a car, Cheng Yanjin quickly caught up with Li Hao, reached out and grabbed Li Hao's collar, lifted him up, and put him horizontally on the horse's back, still in that long-lost posture, so ashamed.

Li Hao danced with his hands and feet: "Let go of me, let go of me, you old bastard!" ”

"Yo, dare to scold Lao Tzu!" Cheng Biting Jin raised his hand and slapped him on the buttocks, the force, not to mention the hot pain in the buttocks, he felt that his intestines were trembling, and he was actually pumped to the point of some shit.

Li Hao suddenly had an idea: "Oops, I'm going to, let me down!" Hurry up, or I'll pull you on horseback! ”

Cheng Yanjin was startled when he heard this, his horse was the meat of his heart, and he loved it very much, how could he be willing to let Li Hao's filthy things be defiled, so he hurriedly threw him off the horse and fell Li Hao.

Li Hao got up while rubbing his buttocks, gritted his teeth and scolded: "Old bastard, when you are too old to walk, Lao Tzu will take you to bungee jumping, and after jumping, I will ask you if the sting is not exciting, and the wrong answer is a big ear scraper......"

"What are you muttering?" Cheng Biting Jin asked with a broken gong in his throat.

Li Hao smiled all over his face: "I'm praising Uncle Cheng for his wisdom and martial arts, and his strength is infinite." ”

"Although Lao Tzu hasn't read much, he is not stupid!" Cheng Biting Jin snorted coldly, "Aren't you going to?" ”
