Inside the cafeteria, the atmosphere is a little solemn.

Because what everyone is facing now is a problem that has plagued the Central Plains Dynasty in the past dynasties.

Faced with the hidden danger of the grassland barbarians going south to plunder and harass at all times, they have never been able to find a suitable way to solve it.

Take the initiative to fight, when you get to other people's territory, you may not be able to beat it!

Even if the dynasty is strong and the army is outstanding, even if you can fight it, people are not stupid, they can't beat it and turn around and run away, and plunge into the vast grassland, you can't find it anywhere!

And even if the battle out of the fortress is won, it will not be of much benefit to the Central Plains Dynasty, but it will invest a lot of money, food and materials because of the expedition, which is simply more than worth the loss!

If you don't get out of the jam, you can only hide in the Great Wall and be beaten passively, enduring the grassland barbarians going south to plunder from time to time, which is absolutely intolerable for any dynasty and any emperor!

For example, Zhu Yuanzhang, the founding emperor of the Ming Dynasty and Emperor Taizu Gao, after driving the Mengyuan barbarians out of the Central Plains and retreating to Mobei, he could not tolerate these remnant forces always entrenched in the Mobei area, always ready to reorganize the army and make a comeback into the Ming Dynasty.

So since the establishment of the Ming Dynasty, Taizu Zhu Yuanzhang has carried out thirteen Northern Expeditions against the remnants of the Northern Yuan Dynasty!

During the Hongwu period, the imperial court sent troops to Mongolia many times, and successively made thirteen northern expeditions to the remnants of the Mongol Yuan forces in Mobei.

But what is the end result?

The Ming Dynasty completely crippled the Northern Yuan, and even Lan Yu completely destroyed the ruling system of the Northern Yuan Dynasty in the fishing sea, but in the end, the Ming Dynasty still had to build a northern defense line to resist the Mongolian barbarians who invaded and attacked from the south from time to time, and there was no other way!

Everyone present now feels how powerless they are when they face the problems faced by Emperor Taizu Gao at the beginning, and even the difficulties faced by the emperors of the Central Plains in previous dynasties!

At this time, the big fat suddenly looked at Su Yang.

"Brother-in-law, what did you suddenly mention about this?"

"Could it be that you have a way to solve this eternal hidden danger?"

As soon as these words came out, everyone looked at Su Yang, their eyes full of shock and doubt.

Su Yang, an immortal, is there really a way to solve this eternal hidden danger and accomplish a feat that Emperor Taizu Gao could not do?

Facing everyone's eyes, Su Yang just smiled faintly.

"First of all, we have to understand one thing, what is the essence of this hidden danger."

"As Master Daoyan said, the Central Plains has not been able to solve this hidden danger, and the fundamental reason is that the grassland is useless to the Central Plains, right?"

When everyone heard this, they all nodded subconsciously.

Because Monk Fang Cai Daoyan has said it very clearly, and this is indeed the case.

Even if the Central Plains army defeated the grassland barbarians, but in a huge grassland, except for cattle, sheep and horses, there is nothing that the Central Plains army can look at.

On the contrary, in order to go out of the fortress to fight, the Central Plains Dynasty had to mobilize a large amount of money, grain and manpower, and the two were simply worth the losses in comparison!

"That's the essence of what I just mentioned."

"The essential reason for this hidden danger is that this is a collision between two civilizations!"

Everyone: "???"

Civilization?

A collision of two civilizations?

Everyone was a little puzzled, and continued to listen patiently.

"The Chinese nation has always been an agricultural civilization, and has established dynasties based on agriculture, both in terms of productivity and technical level, far beyond the nomadic civilization!"

"The steppe barbarians, on the other hand, are nomadic civilizations, living by water and grass, and believing in the law of the jungle, so they don't produce anything, they rely on plunder."

"This is also the reason why the grassland barbarians often go south to solve the attack, because they are born robbers and thieves, and plundering has long been a gene and instinct carved into their bones!"

Crowd: "!!"

Agrarian civilization!

Nomadic civilization!

Productivity!

Plunder!

Hearing these novel words, even the Dao Yan monk felt a little dazed.

For these words he had never heard before, and had never seen them in any book.

However, everyone is not a mediocre person, and with their own knowledge and opinions, they can roughly understand the meaning of these new words.

For example, this "agricultural civilization" should refer to the national civilization based on agricultural production, which was the case in the Central Plains Dynasty for all dynasties.

Su Yang looked at Monk Daoyan.

"What the master just said, the root cause has been pointed out, but the essence is missing."

"Our Central Plains farming civilization has never been able to solve the grassland nomadic civilization, because the farming civilization is centered on cultivating the land and cultivating the land, and the grassland desert is not only unable to grow food, but also to send manpower to garrison, so it will become a useless burden!"

"The land of the grassland desert is not suitable for cultivation at all, even if we forcibly beat away the grassland barbarians and occupy this huge grassland, but not being able to grow food means that there is no output, but in order to strategize these desert grasslands, the imperial court also wants the imperial court to establish a dense military fort from the Great Wall to the desert grassland, and then transport countless grains of the Ming Dynasty to the desert in a steady stream, so as to maintain the survival of the garrison in the desert grassland, so that these desert grass principles have become a burden on the Central Plains Dynasty!"

"If you can't grow food, then there will be no output, and the Central Plains Dynasty will invest a lot of money and grain to maintain the livelihood of the garrison, no matter from which point of view, this is not a wise choice, so the Central Plains Dynasty has never occupied the grassland desert one day, and the Central Plains farming civilization seems to never be able to defeat the grassland nomadic civilization."

"On the contrary, the steppe nomadic civilization took advantage of the weakness of the agricultural civilization in the Central Plains, and twice took advantage of the situation to invade the south and directly occupied the huge Central Plains, one was the Wuhu Rebellion in the last years of the Eastern Jin Dynasty, and the other was the Mongolian iron cavalry went south, each time it brought a painful blow and trauma to the Central Plains agricultural civilization!"

A collision between two civilizations!

The Central Plains farming civilization has already lost twice!

Everyone's faces were quite ugly, and they also looked a little angry.

Whether it is the Wuhu Rebellion or the southward movement of Mongolia, it can be called the darkest and most tragic era in Chinese history.

The land of China is in mourning, and the people are miserable, and they have been being bullied and fleeing on the road, living a miserable life like purgatory on earth.

Zhu Gaochi was a little angry, and his fat face turned red.

"Brother-in-law, is there really no solution?"

"I'm really fed up, this desert steppe land, first the Qin and Hu people, then the Qin and Han dynasties, then the Xiongnu in the Qin and Han dynasties, then the Xianbei in the Three Kingdoms period, then the Turks in the Sui and Tang dynasties, then the Khitan Jin people in the pre-Song period, and finally Mongolia, and now it has become Tatar and Warat, as if there is really no end, killing and killing endlessly!"

"Is there really no long-term solution? Will our atomic people live under the threat and fear of the steppe barbarians for generations? ”

Hearing this, Su Yang took a sip of tea.

"It's not that there is no way, as long as our atomic people can grow food on the desert grassland, then this hidden danger can naturally be solved!"

"Grow food on the desert steppe?" Zhu Gaochi was dumbfounded and complained: "How is this possible! As you just said, the desert steppe is not suitable for cultivation at all......

Before the words fell, Zhu Gaochi suddenly thought of something, his pupils shrank suddenly, and his whole body began to tremble with excitement.

"Brother-in-law...... What do you mean......"

Su Yang nodded with a smile, a smile on the corner of his mouth.

"Otherwise, why do you think I attach so much importance to this potato?"
