Pulling back the scattered thoughts, Liu Hong was a little tired, and waved He Guangsu to retreat.

In the end, Liu Hong's treatment of He Guangsu was: don't take it as an example, and then return to the city from Anmen after dawn.

Although Liu Hong already has plans to open the mountain ban, after all, it has not yet been done, and the law at this time clearly stipulates that it is not allowed to cut down trees without permission; Liu Hong also did not want the legal order to be destroyed, so he could only forcibly pardon He Guangsu's crimes as the emperor.

The current situation of the people at the bottom of Chang'an has inspired Liu Hong a lot, for example: Liu Hong knows what the biggest problem facing the people at the bottom is now.

-- There is not enough food to eat, and there is not enough land to grow.

If we want to solve the problem of acres, we need to open up wasteland; Not only does it take a long time and produce slow results, but it will also increase the burden on the people - this kind of state-led project requires the people to work for free!

Even at the beginning of the 21st century, this kind of unpaid labor also existed in remote mountain villages—forced labor.

The people themselves are responsible for food, lodging, infrastructure construction such as digging ditches, building roads, etc., and providing free and unpaid labor.

This is contrary to Liu Hongdi's original intention - Liu Hong cannot increase the burden of the people now in order to reduce the burden of the people in the future.

Therefore, we can only start from the aspect of grain production.

At this time, the people's rations were generally based on corn.

Corn, easy to grow, the requirements for climate and moisture are not very high, and there is no need for intensive cultivation, only need to sow seeds in the spring, irrigate several times in the summer, occasionally remove insects, clean up weeds, and harvest in autumn.

However, the yield of corn is not very high.

Perhaps for the people today, the yield of corn is close to three stones, but Liu Hong knows very well: even in the best soil environment, the upper limit of corn production will not exceed five stones.

Han one stone is one hundred and twenty catties (Han jin), which is about equal to thirty kilograms; Nowadays, the vast majority of acres of land have a corn yield of about three stones.

In bitter cold places such as Shang and Dai, mass production will be as low as two stones per mu, or even one and a half stones.

Even if calculated according to three stones, the yield of corn per mu at this time is only 90 kilograms.

What was the yield of wheat in later generations?

Under natural conditions, 400 to 500 kilograms per mu!

In later generations, one acre was about 667 square meters, and one acre at this time was one step wide and two hundred and forty steps long; One step is about 1.5 meters; In other words, one acre at this time is about 540 square meters.

Even if the improvement and evolution of wheat in later generations are excluded, the upper yield of today's primitive wheat is much higher than that of corn.

At this time, wheat was also grown, but no one wanted to eat it - because the wheat grains at this time were not ground into flour and then mixed with flour, but directly steamed into grains, or boiled.

That taste... It can only be described in words!

As long as they did not starve to death, the people generally did not want to eat steamed wheat rice.

Therefore, in order for the people to accept wheat as the main ration, it is necessary to solve the problem of wheat flour grinding, that is, to invent a stone mill for grinding flour.

This belongs to the category of technology, Liu Hong still has a small amount of money, and he still has the ability to research and develop.

Putting aside the matter of food for the time being, Liu Hong turned his head slightly and looked at Chai Wu with a pensive face.

Today's play is obviously Chai Wu's attempt to explore Liu Hong's character through He Guangsu.

- Otherwise, there is no need for Chai Wu to be a general and hand over an ordinary person to Liu Hong for disposal; Directly sent to Tingwei, it is rare for Chai Wu to serve the public.

Looking at Chai Wu's slightly solemn expression, Liu Hong smiled secretly: It seems that this general is not very satisfied with himself.

However, Liu Hong will not change his mind because of this: as a later generation, Liu Hong cannot be as cold-blooded and ruthless as the person in power at this time!

At least for the people at the bottom, Liu Hong can't be cold-blooded and ruthless.

Of course, Liu Hong was not stupid enough to pursue this for himself, so he delayed the business and labeled himself as a 'benevolent and weak'.

Just thinking about it, Chai Wuluo's somewhat heavy voice came: "Your Majesty, in Chang'an City, there is chaos to the point?" ”

Hearing this, Liu Hong was stunned for a moment, and looked at Chai Wu in confusion: Is Chang'an City in turmoil?

Except that the emperor himself is not sitting on the throne, it seems to be quite normal, right?

Seeing Liu Hong's face full of confusion, Chai Wu said suspiciously: "The minister heard that the first words of the Qian, Your Majesty opened the grain to sell to the people?" ”

Liu Hong smiled bitterly and shook his head: "However, Chang'an Haoqiang colluded to raise the price of grain, and the corn stone exceeded 400 yuan. ”

"I have nothing to do, and the officials in the DPRK and China are helpless, so I have to open the Shaofu to store grain to stabilize the price of grain."

After speaking, Liu Hong seemed to suddenly remember something, hurriedly got up, and became entangled like he wanted to speak and stopped.

Chai Wu also hurriedly got up and bowed: "Your Majesty can say bluntly, and the minister will not give up." ”

Liu Hong breathed a sigh of relief at this time, and said with a little guilt: "The general rushed to Chang'an in the starry night, I shouldn't have worked too much on the general." ”

"However, this matter must be done before sunrise!"

Hearing this, Chai Wu cooperated with a confused expression: "Why is it so hasty?" ”

I saw Liu Hong frowning, and there was a hint of resentment in his eyes: "The prices in Chang'an are boiling, all of them are headed by the Anling Du family, and Yitun grain is strange to make profits!" ”

Saying that, Liu Hong's face was fierce, and his eyes were full of murderous intent: "Please also ask the general to send 100 soldiers to Anling and take the Du family to Nanying!" ”

"Tomorrow at noon, the Du family will be cut in the East City!"

Looking at the little emperor who was only thirteen years old in front of him, and gave the order of 'raiding the family and destroying the ancestors' with fierce eyes, Chai Wu's eyes slowly lit up, and his face was dark with approval.

- That's right!

Emperor Taizu's bloodline, how could it be a sissy?

With a smile and a hand, Chai Wu bowed indifferently: "Your Majesty, don't worry, the minister will send people to Anlingyi and take the Du family to the door!" ”

Seeing that Chai Wu was about to turn around and leave, Liu Hong came out again and called Chai Wu again.

Seeing Chai Wu's obviously joyful face, Liu Hong put his hands behind his back and walked towards the curtain slowly.

When passing by Chai Wu's side, he said as if talking to himself: "It is rumored that the Anling Du clan has more than 500,000 stones of grain..."

"Tsk, if I have so much grain, the price of grain in Chang'an should be determined!"

As he spoke, Liu Hong glanced at the depths of Chai Wu's gaze, smiled intriguingly, and walked out of the tent.

"I rested in the side tent for a while, waiting for the good news of the general."

Listening to the voice coming from outside the tent, Chai Wu couldn't hold back his joy anymore, smiled knowingly, and bowed to the outside of the tent: "Minister, obey Your Majesty's holy decree!" ”

Liu Hong, who walked out of the tent, smiled indifferently, continued to walk forward, and explained to the insect behind him: "Wei Wei should also go and do things." ”

"The general goes to Anling, the way is more than ten miles, and the Weiwei goes to Weiyang, the way is not more than a few miles."

As he spoke, Liu Hong turned his head with a smile and looked at Worm Da's slightly confused face: "No, the generals have all returned from Anlingyi, and the Weiwei hasn't finished the matter yet, right?" ”
