The assassination of the emperor was intense, and it was extinguished relatively quickly.

The escaped Assassin was never caught, so he had no choice but to hold on to the city gates, using this stupid method to guard the rabbit.

Wei Chi Jingde returned to Taipingfang in frustration, he had already talked to Li Shimin, and he knew very well what Li Shimin meant, and he also knew that this time it was really not King Qi's hand.

Wei Chi Jingde, who returned to Taipingfang, was embarrassed, King Qi treated himself well, entertained him with good food and drink, and talked to himself a lot of heart-wrenching words on weekdays, but when it came to the moment, he threatened to kill him, and replace it with anyone, in this case, I am afraid that it will be embarrassing to meet again.

Simply, Wei Chi Jingde directly drank and got drunk, directly drunk and unconscious, and the province was at a loss to see King Qi again.

Backyard, in a makeshift workshop.

Carpenter Jiang Dahu is holding a tool, knocking on this wooden plow, the wooden plow is still the wooden plow, but after Jiang Dahu's hand came out, there is a different feeling, in other words, this is a finished wooden plow, not only the appearance is good-looking, the connection of each part can also play the best effect of fixing.

These changes may seem small, but in practice they are more durable than ordinary wooden plows.

The pear knife has been replaced by the iron pear knife, and now it is the experimental stage, and there is no need to go in order to save iron materials, and it is a big deal to return to the furnace to rebuild after use, in terms of funds and materials, Li Yuanji is still very generous.

"Yes, such a beautiful object can be put on display." Circling around the wooden plow, Li Yuanji couldn't help but sigh, what kind of farm tool is this? It's a work of art.

"His Royal Highness said with a smile, the exquisite wooden plough is also made for farming, and this is also the credit of Jiang Dahu, when it is promoted, I am afraid that it will not be so handsome." Yuan Rang said a little proudly, although he gave the credit to Jiang Dahu, but he was the real hero, without his own ideas, how could they make such an advanced wooden plow?

Although only a pear knife was replaced.

"Have you ever tried?" Li Yuanji did not have much hope for this wooden plough, because except for the pear knife replaced with iron, nothing else has been changed, and even if it is improved, the magnitude will not be too large.

"I've tried, and a cow can be easily pulled." Yuan Rang said proudly, as the commander-in-chief, and a guy who has drunk ink, except for him, no one else can say one, two, three.

"What about stamina?"

"Endurance?" The smile on his face instantly froze, "Your Highness, this wooden plough has just been made, and the small one has just been tried, and there is no time to test it more." ”

"Then go to the test, the place is not enough to go outside the city, an ox can also pull an ordinary wooden plow, but endurance is not good, we study agricultural tools is not just to replace some parts, but to greatly save manpower and animal power, when an old pack horse can pull this plow easily turned over two or three acres of land, this plow is considered a successful research." Li Yuanji naturally induced.

You have to instill this kind of thinking in them at the beginning, otherwise once they become dependent on themselves, they will be busy in the future.

"This ......" Yuan Rang was instantly shocked into a cold sweat, and the smugness in his heart instantly dissipated.

Only then did he realize that this Jiupin official was not so easy to be, and for the first time he really felt a huge pressure on his body, King Qi did not care about manpower, material and financial resources for his own research, and as a result, it took more than a dozen times to come up with such a thing, even if King Qi was not angry, Yuan Rang also pinched a cold sweat for himself.

For example, if the king wants a person to lie down and kick the other party's abdomen with his foot, his first posture must be to kneel or lie down, but if he kicks on the calf, he will inevitably lie down, and the result is completely different.

Another example is the butcher, they often know where to cut from, from which angle to cut the knife can be the fastest, the most labor-saving, the arrangement of the pear knife should be the same reason, these need you to study, to find, spend more time and financial resources does not matter, and when you research out the wooden plough that can be easily pulled by two or three strong men, you will feel that your efforts are not in vain. "In the next generation, Yuan Rang, who thinks that Lao Tzu is very good, is not a top student in an ordinary middle school, and all kinds of brain-opening ideas will make Yuan Rang die of shame.

But in the Tang Dynasty, in this era of closed-mindedness, a guy who could think of saving manpower and animal power by improving tools was not a genius, but at least a master.

Although Li Yuanji does not understand scientific research, he also knows how to make bold assumptions and carefully verify this truth, which is exactly what he is handed over to them now.

"No! The little ones are all over again. Yuan Rang lowered his head and said, at this moment, he didn't have a little confidence in his heart, his idea had been realized, but after the results came out, he knew that the distance was 108,000 miles.

"Your Highness, I finally found you......" Ma Zhou panicked, and walked to the backyard with a happy expression, the temperature was close to freezing, but Ma Zhou's forehead was sweating, and he could faintly see the steaming heat rising.

"Got a result? So happy? ”

"There we have, but it's not the final result yet." Ma Zhou nodded excitedly, he was completing a great project, and once completed, future generations would benefit from it.

But with the previous lesson, Ma Zhou was extra careful this time, subdividing the entire test into four steps, and planned to complete the experiment in half a year.

But......

The effect is so good, just over a month later, the second step has come to an end, and Ma Zhou is planning to carry out the third step.

"The second step is nearing the end, we have obtained a complete set of data, eliminating a part of the food that is effective when eaten alone, and the effect of eating is not obvious or not improved at all. However, the little one also wants to ask His Highness to allocate another sum of money. ”

"What? Eat up the ones that were acquired in advance? Li Yuanji was a little surprised, it had made people collect a lot of food before, and the three thousand people should not have eaten so quickly if they let go of eating.

"No, after all, these things are relatively expensive, and ordinary people can't afford them, and if they are popularized on a large scale, there are too many troops, and it is also a huge burden on the imperial court. If you can find a cheap food with even worse results, it will be worth it for Datang. Ma Zhou said with some apprehension, it is not easy to find it, after all, after a lot of visits and investigations, they have basically mastered everyone's recipes, and it is difficult to find other foods.

Yes, yes, but Datang doesn't, carrots are a good substitute, and the effect is not bad, but that thing is still in West Asia, only known to be native to Afghanistan, but Afghanistan is now called I don't know, but enthusiasm can't be hit......

"Yes, there is progress, but for now you should concentrate on your experiments, and wait until the beginning of spring next year to start this matter." Now that the winter is bitterly cold, everything is expensive to death, and there is no reason to support high-priced goods, right?

"No! For the small ones, you can make a plan in advance, and then you can start directly. Ma Zhou nodded again and again, he forgot about the shortage of winter supplies.

"Before that, write a detailed report first, it's been more than a month, and it's time for the emperor to see the results." Squinting his eyes slightly, painting a big pie is not safe after all, he has to come up with something that can calm Li Er, in order to ensure his long-term safety and solve night blindness, for the army, there is undoubtedly an extra weapon to kill, and there is a little more hope for victory, which is enough for Li Shimin to be shocked.
