Li Qinzai's agricultural knowledge is very poor, in his previous life he was a small white-collar worker in front of the desk of an urban office building, his limbs were not diligent, and he did not distinguish between grains, and the only agricultural knowledge he knew was to pee and fertilize peony flowers.

It turns out that he seems to have some misunderstanding of this knowledge point......

But in his previous life, he vaguely knew that in the south with a hot or warm climate, such as Jiangnan, Lingnan, Qiongnan and other places, it is possible to grow sweet potatoes twice a year.

It's just that Li Qinzai doesn't have much confidence in this agricultural knowledge. After watering the peony flowers with his only agricultural knowledge, he was beaten with a stick by his grandfather Li Tao and disappeared without a trace.

Today, King Teng came back from the south and finally brought good news to Li Qinzai.

Obviously, he was right, sweet potatoes can indeed be harvested twice a year in the south, and the yield is not low.

If Li Zhiruo knows the news, he will probably be so happy that he will be sick, right? After all, this news is directly related to the Li family's imperial power and the consolidation of rule.

Li Qinzai was very satisfied with this result, and he did not have to worry about the sweet potato matter in the future, since its habits and yield had been confirmed, the imperial court would naturally appoint professional officials to preside over the promotion of sweet potato planting.

"Has the news been sent to the Taiji Palace?" Li Qinzai asked King Teng's guards.

The guard said: "Today, someone has been sent to send the sweet potatoes to the palace." ”

"Your Royal Highness has done another great thing, and he will definitely give you a money increase when he comes back, if he doesn't go up, you will strike, and you can't get used to him." Li Qinzai was full of malice and provoked.

The guard's right hand subconsciously reached for the horizontal knife on his waist, and quickly withdrew it before it touched the hilt.

Li Qinzai's heart was shocked, it was just a provocation, this thing shouldn't want to cut him, right? It's too much!

Decisively turned around and entered the door, and stood in the front hall and watched for a while.

Cui Linqian and Teng Wang's wine fight has reached a fever pitch.

The two old men were flushed, and there were several empty wine jars scattered under the low table, and the two of them were flushed, glaring at each other, and neither of them was convinced.

It's a burning picture.

Li Qinzai got closer and found that the amount of alcohol between the two of them seemed to have reached the end of the crossbow, and their bodies were a little shaky, and they were still gritting their teeth.

It feels like what they are fighting for now is not the amount of alcohol, but the last trace of dignity, and whoever falls first will be completely faceless.

The competition between men is sometimes very inexplicable, especially in terms of alcohol and sexual affairs, and it is directly related to dignity.

When the competition is fierce, they may forget what they are competing for, and in the end they are just fighting for their own dignity.

Li Qinzai estimated that at this time, the two old fathers-in-law may have forgotten their virtuous sons-in-law and forgot the original intention of fighting wine.

Even if Li Qinzai danced in front of them at the moment, they wouldn't even lift their eyelids, and all their energy was used to support their crumbling bodies.

Thinking of this, Li Qinzai couldn't help but have an impulse in his heart, wanting to run to the hall and do everything he could to provoke, "Come on, hit me"......

Fortunately, reason restrained his impulses, and he has been a father twice, so he can't be too cheap in life and bring a bad example to his children.

Quietly walking to the side of Cui Jie and Jin Xiang, who were watching the excitement under the verandah of the hall, Li Qinzai asked quietly, "What's the situation?" Haven't decided yet? ”

Cui Jie snorted and said, "They are all dying to save face, obviously a gust of wind can blow them down, but they still refuse to admit that they are drunk." ”

Jin Xiang sighed and said, "These two ...... Why do you want to drink alcohol? ”

Li Qinzai said steadily: "I am unhappy for my daughter, one thinks that his virtuous son-in-law marries too many mothers-in-law, and the other is unwilling to let his daughter be a concubine for his virtuous son-in-law......"

Cui Jie snorted: "Our family's own affairs, what are they meddling indiscriminately, and how are we living, don't we know ourselves?" ”

Jin Xiang hugged Li Qinzai's arm and said softly: "My father always thinks that I am not doing well, but I am actually very satisfied with such a day, with my husband and sister under the same roof, without the intrigues of the big families, the concubine has always been very blessed, if I can always be like this in this life, what more can the husband ask for." ”

Jin Xiang's face showed a happy smile, her words were obviously not fake, but sincere.

Cui Jie said sourly on the side: "Whether the days to come will always be like this depends on whether the husband is willing, if we add seven or eight more sisters, our backyard will be full of swords and swords, and this day will not be so pleasant." ”

Li Qinzai grinned: "Madame is too worried, even if I am willing, my waist is not happy, squeeze me dry, the Son of Heaven gave our family a pro-book plaque, 'full of widows', it's not a glorious thing." ”

The husband and wife were chatting about idle days, when they suddenly heard Cui Lin in the hall slap the table humbly and shouted: "Brother Yuanying, do you dare to come again?" ”

Not to be outdone, King Teng said: "Come on!" ”

Cui Jie was anxious: "Husband wants to find a way, if you continue to fight, you will hurt yourself." ”

Jin Xiang also hurriedly said: "Father's alcohol consumption is already the limit, and he can't drink anymore." ”

Li Qinzai pondered for a moment and said, "Madame called the two ugliest maids from the backyard and danced the most sassy dance in front of them......

"Why?" Cui Jie asked in amazement.

"Don't ask, ask is fun." Li Qinzai said with a straight face.

The ugliest maid soon came, and Li Qinzai only glanced at them, then quickly turned his head away, trying not to make eye contact with them.

Although it is rude to evaluate other people's appearances, these two maids are really ......

Not to mention the pockmarked acne on her face, she also squinted her eyes and garlic nose, Nuwa Niangniang must have been dozing off when she made them, and she found that it was wasted when she pinched it, and after throwing it away, she accidentally let them come back to life, and they became what they are now.

The two ugly maids couldn't dance, but under the pressure of Li Qinzai's half-step grandmaster Dacheng's momentum, they still walked into the front hall tremblingly, and tried to twist a few times in front of Cui Linqian and King Teng.

The results are remarkable.

Almost a moment later, Cui Linqian and King Teng's faces turned green, and then at the same moment, they leaned over and vomited, yellow and green spit all over the ground, and the hall was stinky.

After spitting, Cui Linqian and King Teng looked at Li Qinzai outside the hall together, their lips opened and closed a few times, as if they wanted to swear, and finally laughed a few times and fell to the ground with a bang.

Li Qinzai clapped his hands: "Isn't this solved, come here, wash the two old fathers-in-law, and send them to the wing room to rest." ”

Cui Jie and Jin Xiang looked at him with admiration, Li Qinzai smiled coldly, turned around and left, leaving them with a majestic back.

…………

Tai Chi Palace.

King Teng's song and more than 2,000 catties of harvested sweet potatoes were placed in front of Li Zhi.

Li Zhi rubbed his hands together and excitedly paced back and forth in front of the pile of sweet potatoes.

"Dozens of catties of grain, but after one season, more than 2,000 catties were harvested? Haha, good, good! Li Zhi's face was excited.

At the beginning, a few sweet potato grain varieties were harvested only a few dozen catties, but after the calculations of the courtiers, Li Qinzai's statement of 5,000 catties per mu was not a lie.

Now more than 2,000 catties of sweet potatoes once again prove that what Li Qinzai said is true.

What does such an astonishing yield per mu represent for the Li Tang royal family and Datang Sheji?

No one knows better than Li Zhi.

Unless the rulers of the Tang Dynasty are extremely corrupt and cruel, even if they encounter a disaster year, there will be no more miserable situation of starvation for thousands of miles and eating for children.

This merit is greater than the expansion of the territory, and it is an unprecedented and unprecedented.

It is no exaggeration to say that sweet potatoes can at least continue the life of the Tang Dynasty for hundreds of years.

How can you not reward the world's achievements?
