"Since Emperor Tang has this confidence, it is a good thing. Yukihime, it's back! Lu Hanyang made Xue Ji change back, but the room did become a lot cooler, which made Lu Hanyang discover a new role for Xue Ji.

It's just a humanoid air conditioner, and as long as you turn it on from time to time, it's enough to make the heat better.

"The immortal chief has traveled thousands of miles this time, obviously he has a different harvest, right?" Li Er asked curiously, originally he wanted to ask about this thing, Lu Hanyang has always had a lot of good things in his hands, which Li Er has always been dying.

"That's right, this seat went overseas this time, for these good things, the Tang Dynasty is a country, and naturally needs these new crops!" Lu Hanyang said.

"Immortal Chang brought back a new crop this time? How does it compare to that Champa rice? Li Er's eyes suddenly lit up, he tasted the sweetness, Zhancheng rice is ripe three times a year, and now Lingnan has become the granary of Datang, although the rice is not as good as his white flour steamed buns from snacks to large, but when he didn't eat it, this white rice was completely life-saving!

Not only white rice, even a bowl of white rice porridge is a life-saving, and even the bran left by those rice can be made into steamed buns and become the food in the mouths of the people.

This year, after the locust plague, the people of the Tang Dynasty relied on the rice transported from the south to save an unknown number of people, and those chaff buns were all sought-after goods.

"This time I got several new crops, two of which can be promoted as food, one is a vegetable, and the other is a seasoning, but it is not a spice, it is similar to dogwood." Lu Hanyang said.

As he spoke, he took out these crops from the storage ring: corn, potatoes, tomatoes, peppers.

This is Lu Hanyang's main goal to go to the Americas, and it is also what he has to find when he searches for most of the American continent, after all, the yield of potatoes per mu is completely representative of high-yield crops, and Datang is now short of grain. In addition, the yield of corn is much higher than that of wheat, and of course, corn milling can be compared with wheat.

Not only that, corn is also better harvested than wheat, wheat is easy to fall a little bit, and it is not easy to harvest, so the corn will be directly broken home with the corn cob, and then woven into a large hanging corn cob to hang up, and then get it down when you want to eat.

Wheat is not good, so this is also an advantage. At least it's easier to harvest than wheat, and the yield is much higher.

In later generations, wheat yields were comparable to those of corn, but that was the result of good management, and it is clearly not possible now. Moreover, the varieties of wheat are not the same, and the current wheat is still the kind of variety with small ears and small grains, and it has become a high-yield wheat in later generations after thousands of years of improvement.

The variety of corn has basically not changed during this time, even if the corn cob is smaller, but it is not much smaller.

So when Li Er saw the fist-sized potatoes that Lu Hanyang took out, as well as the half-foot-long corn cob, red tomatoes and peppers, he stared at the golden corn at first sight.

Not only does corn look the best, but he can see that among these crops, only corn is the grain through and through.

"Immortal Chief, what kind of grain is this crop? What is the yield? Li Er first picked up the corn cob and asked. He believed that this kind of food was worth Lu Hanyang's journey of thousands of miles, and it was obviously definitely worth the money.

"Emperor Tang, what you got is corn, this is a kind of grain, pure grain, it can be boiled directly in the whole water when it is not fully ripe, and it tastes delicious. Of course, when it is fully ripe, it is now golden brown, and these corn seeds are broken down and ground into flour like wheat. Lu Hanyang said.

"So how does the yield of this crop compare to wheat?" Li Er asked.

"At this point, compared to the wheat should be harvested, this seat thinks that it should not be difficult to get higher." Lu Hanyang weighed it, and then said. At present, the yield of wheat in Datang is about two stones per mu, and once it is sixty kilograms, two stones will be two hundred and forty catties.

Although corn is not as long as the cob of corn in later generations, it is not much worse, and five hundred catties should be safe.

"This is a great thing, my Datang people have another kind of food, and it is such a high-yield food! God bless Datang! Li Er's eyebrows fluttered happily, and he even shouted directly.

"Tang Huang, you see, corn is not the biggest target of this seat this time, the biggest goal of this seat is it!" Lu Hanyang said and stretched out his finger to the gray potato. This thing is Lu Hanyang's biggest goal, compared to corn, Lu Hanyang feels that potatoes are more urgent for Datang.

Although corn has a high yield and is also a pure grain, it is still a little worse than potatoes, which are also vegetables and grains, and the yield is two streets behind corn. The production of this thing is completely scary. And it is drought tolerant, and the mountains can survive well.

Wheat is not good, and it is a big problem to grow wheat on the mountains for watering. Therefore, it forms a good complement to the planting structure of Datang.

"Immortal Chief, what kind of crop is this? It looks like it was dug out of the ground. Li Er looked at the potatoes for a moment, and then asked.

"That's right, it's dug out of the soil, it's called a potato, and of course Ihonza prefers to call it a potato. This is a kind of crop that is both vegetables and grain, when there is no food, it can be eaten alone to be full, and when there is food, it is also a delicious dish when it is made into a dish. Lu Hanyang said.

"Immortal Chief said that this potato is the main target this time, why is that?" Li Er asked again, is it pure food like corn that the people need the most? Although this is also good food and food, where is it more expensive than food? There are no vegetables, and you can eat white flour buns.

"This thing doesn't look good, but it has a very high yield, at least three times more than that corn!" Corn Lu Hanyang estimated the output of 500 catties, and he said that 1,500 catties of potatoes is already a very conservative figure. Where this thing is produced in high quantities, it is possible to double his number.

However, Datang's various conditions are not the best, and the output is reduced by half. Even before Lu Hanyang crossed, he had heard of potatoes with a yield of 10,000 catties per mu, but he didn't know if it was hype.

"The yield per mu is three times that of corn, and the yield of corn is twice that of wheat, which means that the yield of this thing is six times that of wheat? Twelve stones per mu? Li Er asked in disbelief.

"That's nature, and I'm still talking less, if not more! This is the reason for this seat to travel thousands of miles! Lu Hanyang said.

"It's a baby!" Li Er directly put down the corn, turned his head and picked up the potatoes, and looked at them carefully.
