Chapter 319 Artificial Respiration and Ten Stones Per Mu? !

Lanqiao Posthouse, beside the Blue River.

Li Erfeng, who was riding a horse, looked at the tall crops in the fields on the shore and wondered, "This doesn't look like millet. Is it sorghum?"

At this time, the leader of the secret agents who were following them quickly stepped forward to greet them.

"Zhao Wenhai."

Li Erfeng pointed to the field nearby and asked, "What is this?"

"Your Majesty." Zhao Wenhai looked conflicted, obviously hesitating about what to say.

"Ok?"

"Your Majesty, this thing is called corn, which means it is as warm as jade." Zhao Wenhai responded stiffly, "It was originally brought out by Taoist Chen, but he said it was a grain seed found by the former crown prince in the mountains."

"It's nothing serious." Li Erfeng didn't care at all. He stroked his beard and smiled. "There are many rare and precious plants in the mountains and forests. What's the problem?"

It's just an empty title, he doesn't care about it at all.

"The Taoist priest Chen said that the yield of corn per mu can reach more than five stones."

Li Erfeng's laughter suddenly stopped.

"How many did you say?!"

In the early Tang Dynasty, millet and wheat were the staple foods.

Due to the influence of geographical environment, such as soil fertility, water resources, etc., the yield per mu is usually around one stone.

The best quality land, with careful cultivation, can produce about three stones per mu.

This is the limit of the earth's power.

The fields near Lanqiaoyi are just above average, but how dare they say that they can produce five stones per mu?
Such a high-yield product has never been produced in all dynasties!
"Don't lie to me."

"I dare not." Zhao Wenhai bowed quickly. "This is what Taoist Master Chen said, but..."

"Just what?" Li Erfeng's face turned black. "If you keep trying to be mysterious, I'll transfer you to the Livestock Bureau!"

Zhao Wenhai was frightened and said quickly, "Your Majesty, we have calculated that the yield of corn per mu is not five stones."

"Haha~~~" Li Erfeng laughed again, "I knew it, it was just a lie."

"More than seven stones"

Li Erfeng'(￣ε(#￣)'

He even subconsciously touched the handle of the knife!
"I dare not speak nonsense." Zhao Wenhai knelt on the ground. "Every word is true."

Li Erfeng, with a gloomy face, simply dismounted and headed straight for the cornfield under the protection of a large group of soldiers.

"Who is it~~~"

Xue Wanche was patrolling the cornfield with a knife, when he suddenly saw Li Erfeng coming towards him with murderous intent. He turned around and left in fear.

"Xue Wanche!" Li Erfeng shouted, "Come here!"

Xue Wanche didn't dare to disobey and could only come over hesitantly.

Li Erfeng pointed at the tall corn stalks rustling in the wind and said, "This thing produces seven dan per mu?!"

"That's about right." Xue Wanche scratched his bald head. "I just harvested an acre of land two days ago. It seems to be this much."

In the modern world, the yield of corn per acre is usually over 1,000 kilograms.

Taking into account factors such as water conservancy, fertilizers, labor, and even the fact that the acreage in the modern world is larger than that in the Tang Dynasty, even if the harvest is cut in half, it will still be 500 kilograms.

In the Tang Dynasty, one dan was roughly equivalent to a little over 100 jin in the modern world. Chen Ran previously said that a yield of five dan per mu was a 50% discount and a guaranteed minimum yield.

The main reason why the yield is as high as seven stones is that the seeds produced by the system are of very high quality, and Chen Ran added fertilizers such as wood ash, plus there is sufficient water source.

Of course, this weight does not include corn cobs. After all, only the Koreans like to eat corn cobs, while the people in Middle-earth eat corn kernels.

Li Erfeng said no more words, reached out and broke off a corn stalk, peeled off the leaves to reveal the bright yellow, densely packed corn kernels inside.

He picked a few and put them into his mouth. The sweet aroma of grain made him take a deep breath involuntarily.

"Where is Taoist Master Chen?"

"I'm in class." Xue Wanche replied honestly, "Today we're talking about artificial respiration and cardiopulmonary resuscitation."

Li Erfeng didn't even finish listening. She turned around and ran towards the post station.

The former post station has now become a school and a clinic.

Many people were queuing in the yard waiting for medical treatment. When they saw Li Erfeng and his group rushing in, they all looked at them sideways.

Li Erfeng was extremely anxious and almost ran in.

As soon as he entered the front hall, he saw his third brother Li Yuanji, who was sitting upright on a stool, treating a patient in front of him.

"Second brother?" Li Yuanji was delighted when he saw Li Erfeng. "Why are you here?"

Looking at his genuine joy, Li Erfeng felt deeply moved. His character had changed so much.

"Where is Taoist Master Chen?"

"Please wait a moment, second brother." Li Yuanji, who used to have a bad temper, now patiently diagnosed the patient in front of him, wrote a prescription, and called the postmaster who also had the opportunity to attend the class to come and take over his job. Then he took Li Erfeng to the back.

Behind the front hall is the back hall, which is filled with various kinds of medicinal materials.

Several postmen were busy processing the medicinal materials, packing and sorting them.

Outside the back hall is a yard, which was originally a place for the post station to house livestock, but now it has become a processing plant for semi-finished medicinal materials.

After crossing the yard and arriving at the back hall, you can see many figures inside through the wide-open doors and windows.

Li Erfeng strode in, opened her mouth to speak but stopped abruptly, staring with wide eyes at the incredible scene in front of her.

His elder brother Li Jiancheng was actually squatting on the ground, giving mouth-to-mouth treatment. What a decadent society! "Artificial respiration is an emergency measure to provide a breath to a patient when he stops breathing suddenly."

Chen Ran glanced at the large group of people at the door, but he was still continuing to teach on the spot, "For respiratory arrest caused by poisoning, drowning, heat stroke, frostbite, etc., this method can be used to save lives."

"Compared to life, nothing else matters."

"Okay, the next student will come up and practice artificial respiration."

Li Jiancheng stood up and saw a large group of people at the door. His expression was a little unnatural.

Chen Ran did not have many students. They were mainly people at the post station, secret sentries, and children from surrounding villages who came to him on their own initiative after hearing the news.

The students had a strong motivation to learn real skills, and lined up one by one to undergo artificial respiration training.

Next, Chen Ran talked about the techniques and theories of cardiopulmonary resuscitation.

Then he motioned to Li Jiancheng to lie down as a patient, and personally explained to the students the corresponding parts, techniques, movements, etc.

"Cardiac resuscitation is mainly a means of emergency rescue for people with cardiac arrest through manual chest compressions."

"What if it's a woman?" Changsun Wuji couldn't help asking, ignoring Li Erfeng who was standing beside him, "If I meet a woman, do I have to take action directly?"

Chen Ran turned and looked over.

'I met the historical figure Changsun Wuji, who was both civil and military, with outstanding abilities and outstanding achievements, and was ranked first on the Lingyan Pavilion list of meritorious officials. He was too calculating, liked to use tricks, and only said nice things in front of others.'

'Note: You can modify two of the words.'

"Isn't this the emperor's brother-in-law?" Chen Ran smiled. "I should have said to you that when your female relatives encounter cardiac arrest, you should follow the etiquette and not help them, and watch them die. But this is not nice to hear, so I won't say it."

Changsun Wuji'（‵□′）'

You've said it all from beginning to end without missing a word!

"How dare you curse me?" Changsun Wuji was furious and drew his sword. "I will fight you!"

He stabbed at him with a sword, but Chen Ran didn't even dodge. He just rushed into the battle with his bare hands and snatched the sword away.

Then he threw him over his shoulder and knocked him to the ground.

Zhang Sun Wuji felt like his bones were about to break, and in anger he said, "Just wait for me, I will definitely take revenge by all means, and I will speak ill of you in front of His Majesty, and let His Majesty kill you all."

Having said this he suddenly came to his senses and bit his tongue hard to stop himself from speaking.

"What's wrong? Why did you say everything that was in your heart? Are you possessed by evil spirits?"

It can be said that he was possessed by evil spirits. Chen Ran changed "only say nice things in front of others" to "only say the truth in front of others".

From now on he won't be able to be a smiling tiger anymore, he will just say whatever he thinks.

'The modification of Changsun Wuji has been completed, and the reward is now issued.'

'Note: One bag of Brassica napus seeds will be distributed (excellent varieties, resistant to insects, diseases and lodging, genetically improved varieties with excellent quality.)'

In fact, rapeseed was introduced to China as early as the Shang and Zhou dynasties, when it was called Brassica juncea.

It’s just that these rapeseeds belong to the cabbage-type rapeseed, which evolved from Chinese cabbage.

The capabilities in all aspects are not strong, the production potential is small, and the stable yield is poor, making it difficult to plant and extract oil on a large scale.

The cabbage rapeseed seeds rewarded by the system are specially cultivated for oil extraction.

Li Erfeng's face didn't look good.

He told Yuchi Jingde who was standing by, "Send him to the front for treatment."

The farce was over and the class could not be held.

Chen Ran simply announced the end of the get out of class and the students went away to eat and rest.

"What brings you here, Your Majesty?"

"Where did all that corn in the field outside the post station come from?"

Compared with other things, Li Erfeng thinks they are all trivial matters, only food is the most important thing.

No matter how much grain the Tang Dynasty collected, it was never enough to eat.

Li Erfeng knew very well that only when there was enough food to fill the stomachs of the people could there be peace in the world.

Chen Ran gestured to Li Jiancheng who was standing beside him, "He found it when he was collecting herbs in the mountains."

Li Jiancheng felt a little ashamed and embarrassed to find that he was the one who got the title of such a high-yield divine grain.
Li Erfeng looked deeply at her good brother.

Although he was somewhat jealous of the fact that this would surely go down in history, it didn't matter. He was more concerned about the actual benefits.

“Is this corn really so productive?”

"We were originally planning to harvest the crops these days." Chen Ran looked at the densely packed guards outside and said with a smile, "I was just worried about not having enough manpower. It just so happens that Your Majesty brought some people here today, so let's start harvesting the crops together."

Li Erfeng did not hesitate at all and nodded immediately "Okay!"

He was accompanied by his retinue, the spies who protected him, and a large group of cavalrymen in the rear, who were all called upon to harvest the corn.

If there is no sickle or anything, just use weapons.

Even the county magistrate of Lantian County was called over for the count.

With so many people working together, the harvest was completed in just half a day.

It was not until this time that Li Erfeng saw the cotton field behind the cornfield.

Looking at the vast expanse of white over there, he was puzzled and asked, "What is that over there?"

Before Chen Ran could respond to him, the Lantian County Magistrate, who was not far away, suddenly let out a terrible and heartbreaking cry.

"Oh my god~~~ One acre of land yielded ten stones of grain?!"
