For the people who cultivated, the plough was like a gospel.

After feeling the benefits brought by Qu Yuan Plow, Liu Bei wanted a talent like Xi Yu in his heart.

It's a pity that he has never met a talent like Xi Yu.

This time he was stationed in Xuzhou, and after seeing the changes in Cao Jun, Liu Bei was even more emotional.

Soon after Liu Bei led his army to be stationed outside Xuzhou, Cao Cao's army began to attack Xuzhou again.

After learning of this situation, Tao Qian hurriedly supervised his generals to resist Cao's army, and directly sent 4,000 Danyang soldiers to Liu Bei.

Then Tian Kai rushed to meet Liu Bei, and Tao Qian made the two garrison Tancheng.

Within a few days, Cao's army repeatedly captured the town of Xuzhou.

Under the collapse of the Xuzhou defense line, Cao's army had begun to occupy Donghai County.

In this situation, Tao Qian could only pin his hopes on Liu Bei, but fortunately, Cao's army stopped after capturing several cities.

Just like the previous four counties.

For this situation, Tao Qian was a little helpless.

By the time he had been there, he had learned why Cao's army had not continued its offensive after capturing the four counties.

The spies came to report that Cao Cao had begun to implement the Yanzhou policy within the four counties.

Because of this.

At this time, Tao Qian knew in his heart that Cao Cao was planning to annex Xuzhou in one go.

And right now, at both ends of the Xuzhou Shi clan, the only henchman he can rely on is Cao Bao.

However, Cao Bao's ability is not too outstanding, and Sun Guan, Tibetan tyrant and others are not the people he relies on, only Liu Xuande leads troops to help.

Liu Bei helped Beihai before, and Kong Rong has spread his reputation!

It is also because of this that Tao Qian also has great trust in Liu Bei, not to mention that the other party is still a member of the Liu family.

Xuzhou City.

After the Cao army resumed its attack, Tao Qian took the initiative to invite Liu Bei to discuss how to resist the Cao army.

In the main hall at this moment, Tao Qian didn't care about the eyes of others, and took the initiative to look at Liu Bei.

"Xuande, is there a good way to resist Cao Jun this time?"

Cao Jun's actions made Tao Qian know that there was no way out of Xuzhou at the moment.

To be precise, it was he Tao Qian who had no way out, and those wealthy families in Xuzhou were just going to serve Cao Cao in the end.

The only person he relied on was Liu Bei.

Is there a good idea?

When Tao Qian asked Liu Bei, the latter couldn't help but sigh in his heart.

Where did he have a good plan!

He also needs someone who can give him a good solution!

However, we are now approaching the depths of winter, and winter is not conducive to combat.

Thinking that as long as it drags on until winter, Cao Cao will inevitably retire from the army in desperation, right?

Thinking like this, Liu Bei raised his eyes and looked at Tao Qian.

"Envoy, now that winter is approaching, Cao Jun's delay is not a bad thing for Xuzhou!"

"Winter is approaching, grain and grass are difficult to transport, and it won't be long before Cao Jun will be short of grain and grass!"

"At that time, Cao Jun will inevitably retreat!"

If you want to resist Cao Cao head-on, Liu Bei has no way.

This time, Cao Cao came with an army of 200,000, even if it was divided into three armies, it was not something he could resist head-on.

Coupled with Tao Qian's 4,000 Danyang soldiers, Liu Beiman's full battle is only 8,000 soldiers, and with Shangtian Kai's 3,000 soldiers, it is only more than 10,000.

How to resist, several, or even dozens of times the number of troops?!

Now, the only way to do it is to defend!

When Cao Jun's food and grass are insufficient, it is a real good policy to retreat naturally.

After Liu Bei's voice came out, Tao Qian was a little helpless, and he naturally knew the truth.

It's just that Yanzhou has a bumper harvest this year, and it may be difficult to get Cao Cao to run out of grain and grass.

And most importantly!

If Cao Cao is really allowed to drag it down like this, it will not only be Dongguan County, but also half of Donghai County.

In the future, I am afraid that it will become the territory of Yanzhou!

Tao Qian was worried, but there was nothing to do.

Chen Deng's father and son on the side did not say a word, Liu Bei had no good strategy, and the morale of the generals was low.

After returning to the station, Liu Bei began to train his soldiers as usual.

And at the same time!

Yanzhou Juancheng!

After inspecting the terrain of the two places, Xi Yu couldn't help but set his eyes on one of the mountain roads.

Xun Yu on the side naturally noticed the mountain road.

It's just that he didn't think of it as a way to transport grain at all.

The mountain road is rugged, and it is not a way to transport grain at all.

And on the entire topographic map, there is no other way to pass.

Xun Yu frowned, and Xi Yu on the side suddenly put the topographic map on the desk, and casually pointed to the mountain road on the map.

"Brother, is this the way through?"

"Huh?"

Xun Yu looked at it, and sure enough, it was the mountain road he saw.

"The road is feasible, but this is a mountain road, which can only be used by people, and it is difficult to transport grain!"

Xun Yu shook his head, it was too difficult to transport grain from the mountain road!

Hearing Xun Yu say that the road was no problem, the corners of Xi Yu's mouth couldn't help but chuckle.

Since the mountain trail is passable, there is no problem!

Who said that the mountain roads can't carry grain?

There are more difficult mountain roads in the whole world than the mountain roads in Xishu?

In another ten years, the famous Prime Minister Zhuge Cheng in later generations will be able to transport grain on the mountain road, which has proved everything.

Of course, at this time, there were no wooden oxen and horses, and such a craft in the previous life has long been lost.

But, to be precise, there is no problem with having a one-wheeler to transport grain.

"Who says you can't transport grain on mountain roads?"

Xi Yu looked at Xun Yu, and then smiled at the corner of his mouth: "This matter will be handed over to me, brother and send a letter to the lord, let him rest assured!" ”

"But it will take a few days, and by then, the grain and grass will naturally arrive on time!"

Xi Yu was full of confidence, and after Xun Yu on the side heard this, his whole eyes couldn't help but light up.

"Fengyi, is this true?!"

He was a little puzzled, how to transport grain on the mountain road.

It's just that as soon as the words came out, Xun Yu couldn't help but smile again.

He forgot, before Xi Yu, he made a zigzag plow, a waterwheel, and a series of other things.

Maybe the mountain road to transport grain will not be difficult for the other party at all.

Thinking like this, Xun Yu followed and nodded: "Fengyi, you just go and do it, I'll send a letter to the lord here!" ”

"In this way, the rest will be left to my brother!"

Xi Yu nodded, and after leaving the Juancheng Office, he began to gather the craftsmen again.

With the previous experience of the waterwheel, the craftsman came very quickly.

Immediately after, the craftsmen led by Ma San soon appeared in front of Xi Yu.

"What are you going to do, sir?"

The previous waterwheel made these craftsmen already admire Xi Yu very much.

The appearance of the waterwheel has made the people of Yanzhou praise a lot even with craftsmen, and these craftsmen are somewhat proud in their hearts.

And all this was not done before.

"Make a car!"

Xi Yu said casually, and then took out the drawings he had just prepared.

It was a drawing of a wheelbarrow.
