Zheng Xiu's treacherous plan still did not succeed after all, and the quick-witted empress avoided this topic without a trace.

"Ahem, Zheng Qing, I have thought of a lot of rewards and rewards for you, but I am afraid that the things I give you are not to your liking, you might as well tell me what you want, and I can make an order according to your hobbies."

When Zheng Xiu heard this, he immediately felt that his opportunity had come, although he couldn't drink alcohol, he could do other things.

He still remembers the last potato turmoil, and this time in order to avoid being so embarrassed as the last time.

So Zheng Xiu decided not to give other rewards, and asked for that corn plant.

Thinking of this, Zheng Xiu opened his mouth and said: "Your Majesty, the minister does have a reluctant request this time, that is, the minister fell in love with a spirit plant on the way to the imperial garden this time. ”

"Originally, a gentleman shouldn't take away people's favors, but that plant is of great significance to the minister, so the minister dared to let His Majesty give it."

When the empress heard this, she didn't immediately reply to Zheng Xiu, after all, there were too many elixir and spiritual plants in the imperial garden.

And if each of them is taken out, it can make the head of the ordinary immortal cultivation sect or the immortal cultivation family break the bloodstream.

But as time passed, Great Xia's national strength was not as strong as before, so many things could only be consumed.

Especially after the national teacher came, he had to come almost every few weeks to ask for the elixir.

In addition, the elixir he refined was indeed effective, even if he knew that the national teacher would deduct some of it, the empress agreed to him.

After all, in Daxia at that time, there were several courtiers who were not greedy, and the corruption ratio of the national teacher was already very conscientious.

After being sacked by the national teacher, the elixir in the imperial garden has either not grown yet.

Or maybe it's a treasured treasure that she herself can't afford to use.

So Zheng Xiu's rash request made him a little embarrassed.

"Aiqing might as well tell me first, what you want is that spirit plant, if it's not anything particularly important, I will give it to you in my personal name."

When the empress said these words, she had already thought about it a lot, such as why Zheng Xiu would ask for Lingzhi.

If you ask for those spirit plants, will it have any impact on Great Xia, and how should you refuse him.

"Back to Your Majesty, the minister wants that longevity flower."

Longevity flowers? It's not impossible, although the people in those farmers are studying this flower and have different opinions about this flower.

Some people believe that this fairy grass does have the effect of prolonging life.

But the other part thinks that this fairy grass has no such effect at all, it is just simply robbing other plants of nutrients.

The two factions have been arguing with each other, but no one can convince anyone, because this fairy grass has long been banned from picking.

Even if the national teacher applied to her many times, wanting to use this immortal medicine to make alchemy and conduct research, she still refused.

After all, it is the safest thing for this kind of thing to be between useful and useless until it is determined whether it is useful or not.

It's just that the rules are dead, people are alive, if Zheng Qing sacrificed a lot of life for Daxia this time.

Then if the other party wants this spirit plant to replenish his lost lifespan, then he will not disagree.

After all, Zheng Xiu is her courtier, and he is one of the few capable ministers, only ministers, and loyal ministers who can be used with confidence.

Just when the empress decided to give away this elixir in pain, Zheng Xiu finally figured out how to describe corn.

"Returning to Your Majesty, the minister wants the plant next to the longevity flower that looks like a guard, with a slender stem and oval fruits on it."

？？？

The empress was puzzled in her heart, wasn't the other party beating the idea of prolonging life?

Or is the other party actually testing himself because he hesitated for a moment before changing his requirements?

Yes, yes, it seems that my Zheng Qing was also moved by me, and finally he is no longer the courtier who is a dumb king and a tyrant with a closed mouth.

His heart is commendable, his heart is commendable, since this is the case, I will definitely reward you with this fairy grass.

"It doesn't matter, if anyone else wants this longevity flower, I may have to think about it before I agree."

"But since Zheng Qing wants this spirit plant to restore his lifespan, I will naturally agree to you."

When Zheng Xiu heard the empress say this, countless question marks immediately appeared in his mind.

It's that I didn't make it clear, or there is something wrong with the empress's ears, and what I said should be corn.

Why can the other party only hear the longevity flower in front of him, but not the corn in the back?

"Your Majesty, have you heard it wrong, what the minister means is that what the minister wants is the corn next to the longevity flower, that is, the one with the stalk green, the ears with earthy yellow, and the fruit with yellow."

The empress looked at Zheng Xiu's serious appearance and didn't seem to be fake, and then she tried hard to recall this plant in her mind.

It's just that she has never cared much about immortality, and she doesn't like flowers and plants, so she can't think of this plant all the time.

However, it turned out to be the plant that Zheng Aiqing wanted, so it must not be ordinary, but I don't know what it does.

"Zheng Qing, if you don't mind, you might as well introduce to this king what the plant you asked for is useful, how about it?"

When Zheng Xiu heard the empress say this, she seriously extracted information about corn from her memories.

Corn is an annual monoecious cross-pollinator plant with tall plants and strong stems, which is an important food crop and fodder crop, and is also the highest total crop in the world, second only to rice and wheat in terms of planting area and total production.

It has a very important position not only in our country, but also in the world's food crops.

First of all, corn has always been known as a longevity food, rich in protein, fat, vitamins, trace elements, fiber, etc., and has great potential for the development of highly nutritious and biologically functional foods.

Secondly, corn has a high yield and is highly adaptable. Corn grains and stems are rich in nutrients and are high-quality feed for all kinds of livestock, with 5.6kg of corn kernels needed for each kilogram of pork produced and 10kg for one kilogram of beef.

The energy contained in 100kg of corn kernels is equivalent to 135kg of oats, 125kg of sorghum, and 130kg of barley.

Therefore, corn is indispensable feed for cattle, horses, sheep, pigs, poultry and fish.

The most important thing is that the whole corn plant can be fed, and the utilization rate is more than 85%.

Whether it is corn kernels, corn gourds, or corn stalks, they are all good feed.

It is completely possible to let the common people eat the corn kernels and then feed the by-products to the livestock.

Moreover, corn has less cellulose and good palatability, and all kinds of domestic animals like to eat it.

If corn is planted on a large scale like potatoes, then Daxia can not only feed the people with potatoes, but also use corn to feed poultry and let the people eat meat, which is probably an event of cross-era significance.

With Zheng Xiu's introduction, the empress's eyes slowly shone brightly.

The importance of eating meat has been known since ancient times, but in agrarian societies, there are only a few people who can eat meat.

After all, you can't even feed people, let alone those slow-growing animals?

But now, if corn is a crop and it is spread to the whole country, then every household will be able to eat meat.
