Li Gang's mouth was wide open, his eyes were about to bulge out, he stood on the ladder for a while, and hurriedly climbed down, so frightened that the two guards who responded exclaimed again and again: "Li Shangshu be careful!" ”

Li Gangcai didn't care about the shouts of the two, almost step by step, he got off the ladder without a beating, and the last step seemed to be unable to wait, and jumped down directly!

"Li Shangshu!"

Now, there are more than two guards, and even Xue Lang was startled, uncle, you have to serve the old, you are old and seventy!

Li Gang almost fell to his knees, Xue Lang hurriedly stepped forward and helped him up: "Li Shangshu, how are you?" Where can it fall? ”

Li Gang is old after all, and if something happens, it will be a big problem.

Li Gang stood up with the help of Xue Lang's strength, moved his hands and feet, and said with a full heart: "It's okay!" If you are old, you will be weak just one step of the stairs! Don't talk nonsense, I'm tired of Xue Counselor helping the old man to go over and take a look! ”

"Okay!"

Xue Lang helped Li Gang close to the pile of sweet potatoes-

Li Gang stared blankly at the sweet potatoes that almost looked like he was sitting on a hill, his mouth never closed, and he muttered to himself: "More than twenty stones!" More than 20 stones! Confucius Sage never imagined that the students would be able to see such a strange thing in their lifetime! The Mandate of Heaven is in Tang, and the Mandate of Heaven is in Tang! ”

Literally, you know a lot when you look at more than 20 stones, but when more than 20 stones are really placed in front of you...... The grain output of this era is only three or four hundred catties, compared with more than 20 stones, just like streams and rivers, ants and elephants, it is simply incomparable!

is as old as Li Gang, and he can't help but lose his temper.

Xue Lang is worried about his age, and he doesn't know if he has heart disease, high blood pressure and other diseases, if there is a case-

Xue Lang simply stopped talking, and waited for him to calm down! Li Yuan is also yes, he won't send a younger one, at least not to make the surprise turn into a frightened age. Seeing that the old man was so excited, Xue Lang was really afraid that the surprise would turn into a fright!

Fortunately, Li Gang has gone through two dynasties, and he is also a person who has seen big scenes, so he was not so excited that he had a heart attack, but just grabbed Xue Lang's hand holding him hard, and Xue Lang couldn't help but complain in his heart-

The old man has good hands! But gave birth to a pair of unicorn arms?

"Counselor Xue!"

Li Gang's voice could still hold on to it, but his excited and trembling arms revealed his emotions: "The cultivation methods of this thing are complicated? Can you pick and choose the fields? If used for seeds, how much land can these seeds be planted on? ”

Xue Lang said: "One acre of land only needs more than ten catties to make seeds." If it is cultivated near Weize Pass, there is no need to use tubers for seeds, and the lower officials have to leave stems for seeds; If you plant it for the first time in a distant place, use tubers as seeds. The land planted is not picked, it is better to dry the land, if it is planted with water, it will affect the yield. ”

Li Gang reacted quickly: "So that is it, just go to the lower field?" ”

Xue Lang dotted the picture: "That's right! ”

Li Gang asked again: "In addition to using tubers as seeds for the first year of cultivation, can you use stems for cultivation in the second year?" Can all the harvested sweet potatoes be kept for consumption? ”

Xue Lang nodded: "Exactly."

"Shhh

Li Gang gasped, there were words in his mouth, Xue Lang listened attentively, Li Gang was actually counting the ratio of seeds to harvests, and in the second year, he directly startled himself! slapped his knee directly, and almost jumped up: "Xue Counselor, can this thing be kept?" Can it be eaten as is? ”

Xue Lang is quite kind to Li Gang's knee-slapping action, he has seen many old men like this before, and he loves to pat his knees when he is excited.

Xue Lang said: "Back to Li Shangshu, sweet potatoes are very convenient to preserve, just like its cultivation method, pay attention when digging, don't dig the skin, you can be like now, pile it in the cellar, and save it until next year." If you are not careful when digging and the skin is broken, you can also save it, but you have to spread it out and save it, not pile it together, otherwise it is easy to rot. ”

Xue Lang paused, and then said: "As for eating, it is simpler, raw can be eaten, cooked can also be eaten, steamed, stewed and simmered, how you want to eat depends on your personal wishes." ”

Li Gangxi said: "In this way, even if it is a poor family, it can be eaten without oil and salt. It's really a good baby, neither picking fields, nor picking people, such an ordinary thing, but there is such an amazing yield, treasures, treasures! ”

After speaking, he didn't want Xue Lang to help him, he circled around the sweet potato pile, and muttered in his mouth: "This is the yield of one acre of land, one acre of land is already so high-yielding, if there are many acres of ...... Hiss! ”

Li Gang was taken aback by his own idea, and immediately thought about it, and said: "In this way, if it is an ordinary family, sweet potatoes can be planted one or two acres every year, and only the inferior fields are needed, and the medium and upper fields can be used to grow other crops, so ......."

Li Gang gasped again, and was directly shocked and speechless!

Xue Lang said: "Li Shangshu, in fact, the preservation method of sweet potatoes is not limited to this, there is also a method, which can be ground into flour like wheat and made into sweet potato vermicelli, so that it can be preserved even if there is no cellar." After all, my Datang territory is vast, and not every state and every household has a cellar. ”

Li Gang asked in surprise: "Can you still make noodles?" ”

Xue Lang smiled: "Naturally, I can, please Li Shangshu move, after the sweet potato harvest, I have been ordered by His Royal Highness to make some vermicelli out, please Li Shangshu come and taste it." ”

Li Gang didn't move, and asked, "The old man may ask, how many sweet potatoes can make a pound of vermicelli?" ”

Xue Lang estimated it and said, "About five catties!" ”

"Ahem, ahem!"

Li Shangshu was directly choked by saliva!

Xue Lang hurriedly helped him calm down, and when his breath stabilized, he was still not at ease: "Li Shangshu, are you okay?" It's better for us to go out first, the cellar is not well ventilated, and staying for a long time may be harmful to our health. ”

"Yes!"

Li Gang also knew that he was too excited, and he was indeed a little uncomfortable in the cellar, so he listened to Xue Lang's advice with kindness.

Compared with going down the ladder, it was much easier to go up, I was afraid that he was old, and he was emotional just now, and his physical strength couldn't keep up, Xue Lang asked the two guards to go up one first, pull some Li Gang on the ladder, follow the one, push the old man, and he himself stayed at the end to go up.

Li Gang had no objection to this arrangement, but glanced at Xue Lang approvingly.

Out of the cellar, Princess Pingyang was still waiting outside with people, Li Gang just came out of the cellar, his little servant immediately ran over to support him, and Princess Pingyang immediately sent someone to hand over water.

Princess Pingyang came over calmly and asked in a harmonious voice, "Li Shangshu, can you check it out?" ”

Li Gang's face was full of excitement: "Your Highness, the old man has checked clearly, the yield is true, sweet potatoes are really treasures, God bless the Tang Dynasty, this auspicious rui is really the ironclad proof of the destiny of the Tang Dynasty!" This is the fruit of the saint's benevolence! ”

Princess Pingyang smiled and followed Li Gang in the direction of Chang'an, and continued to say in a harmonious voice: "Since it has been verified to be true, please Li Shangshu move back to the house and rest for a while, I have ordered someone to prepare a sweet potato banquet and invite Li Shangshu to taste it." ”

"Just now I checked such a surprising treasure as sweet potatoes, and the old man was already curious about how this thing tasted! His Royal Highness entertained the old man, and in this way, the old man bothered His Highness with a cheeky face. ”

"It doesn't matter! It is an honor for Li Shangshu to come to the tasting! Please! ”

"Please!"

The group turned around and went home, and of course, Xue Lang also followed him back home.
