The biggest advantage of potatoes is actually not the high yield, but the extremely low planting requirements.

This thing is not like corn and sweet potatoes. It has certain requirements for ground abilities, water and fertilizer and climate. If you don’t think of large-scale planting in Bashu in less than three or seven or eight years, you can’t imagine that you can grow it on a large scale in Bashu.

Its strongest ability lies in not picking the ground. As long as you give enough water, you can plant it anywhere and take root as soon as you enter the Central Plains.

Even if the yield is not as good as that of the Americas where origin is, it is not comparable to rice and wheat in the Central Plains.

Of course, this is still the original variety from the thirteenth century.

Zhao Wei knew that potatoes are far from reaching the high yield level of later generations, and even one-tenth of them can't reach it, and there is a lot of room for improvement.

At that time, good farmers who are skilled in agriculture will be appointed to improve and breed, so that their potential can truly explode. Even if they cannot reach the level of future generations, they will not be comparable to those of 800.

At this time, Zhang Jue, Wen Tianxiang and others did not notice Zhao Wei's pride at all. They had already gathered around and began to count on their fingers.

"One season is 800, three seasons a year? 2400 kilograms? Twenty chunks? Oh my god!"

The annual output is 20 dan, three times that of today.

If you let go of your belly, you can feed 5 people, which is already scary.

It is equivalent to a family of five that only needs one acre of land to feed.

Of course, if the quota is replenished and the quota is saved, 10 people can survive.

However, Wen Tianxiang, Wang Yinglin and others looked at Zhang Jue.

"Zhang Shuai, do Diaoyu City have so many land?"

They have never been to Diaoyu City, although Zhao Wei took out this bean and created a big surprise.

However, according to their understanding, there are at least 56,000 people in the city. In addition, they can only count 60,000 yuan. Combined with the output that Zhao Wei said, saving money and 6,000 acres of land can support so many people.

Several old husbands were a little unsure. Diaoyu City is a mountain city, a small town covering an area of ​​only more than 4,000 acres.

Moreover, what is a mountain city? It is built on the top of the mountain and is based on steep mountains as a defense. Even if there is a field to cultivate, it will inevitably be rare.

However, unexpectedly, Zhang Jue smiled mysteriously and kept it in hiding by Zhao Wei's appearance.

"You will know that you will arrive at Diaoyu City tomorrow, and there is no problem at all!"

“…”

“…”

Everyone looked at each other and became even more curious about the legendary Diaoyu City.

......

The next morning, everyone boarded the boat early and surrounded by small boats and rafts, advancing towards the fishing city that was a hundred miles away.

Wen Tianxiang and others were obviously a little excited. They stopped entering the cabin and gathered at the bow of the ship, their nervousness was beyond words.

However, what was more excited than the husbands were Dong Laosan and Enyang people, ordinary people.

Along the way, the shouting never stopped.

"Wen Tianxiang is entering Sichuan! Marshal Zhang is back and killing the Tartars!!"

He shouted along the river, and the Śrāvakas were far away.

If Zhao Wei could look down at the river from a high altitude, he would find that after their miscellaneous boats, civil boats heard the shouts from the river one after another, and began to follow the fleet.

Just like ants gathered together, they went straight down the river.

When we reached the intersection of Qujiang and Jialing River, only ten miles away from Diaoyu City, there were no less than ten thousand people coming to see us.

Moreover, as the boats sailed into the wider Jialing River, more people from Hechuan began to gather on the river.

The two sides of the Taiwan Strait are hiking and chasing the fleet, and there are even more densely packed.

Everyone was secretly shocked. If the people of Laitan yesterday were just a glimpse, then now everyone really felt how much influence Zhang Jue had in Bashu.

While praising Zhang Jue for being righteous in his supporters, everyone also looked at Zhao Wei for a few more...

It seems that King Ning’s decision to save Zhang Jue into Shu this time was not a coincidence, but the best move at the moment.

However, the more people gather, the more worried the husbands are.

A crowd of thousands of people gathered in this hundred miles. If the news spreads completely, I wonder how many people will come to join us. How can Diaoyu City really support it?

Just as I was thinking, the river surface took a sharp turn ahead.

When the fleet turned around, I saw a towering city in front of me standing on the bank of the river.

Diaoyu City, arrived!

......

———————

Diaoyu City is located ten miles northeast of Hezhou, guarding the Fu River, Qu River, Jialing River, and the convergence of the three rivers.

Looking down from a high altitude, the Fu River rushes down from the northwest, while the Qu River comes from the northeast. The two rivers are at the same angle and flow into the Jialing River, which is directly north to south.

It's like a trident, dividing the earth into several pieces.

After the Jialing River gathered in the Liangjiang River, it seemed that it did not rush to go south. Instead, it made a sharp turn of 180 degrees east of Hezhou City, flowing north for more than ten miles. When it was about to hit Qujiang, it turned south again.

In this way, a "ji"-shaped Hezhou Peninsula was formed, surrounded by water on three sides and a narrow terrain on one side connected to the continent.

Diaoyu Mountain, where Diaoyu City is located, is surrounded by the terrain surrounded by the three rivers.

The fleet first saw Diaoyu City, but it was in the north. From a distance, the towering mountain top was vaguely exposed.

It took me nearly a week to walk around the peninsula and reach the water pier located to the south.

At this time, the people in the city had already received the news. When General Zhang returned, they all rushed to the dock to welcome General Zhang.

The old husbands and Zhao Wei were all concerned about whether the city was as good as Zhang Jue said, so they collectively gave Zhang Jue the opportunity to accept the people's pursuit.

A few people took advantage of the situation and left, thinking that they would climb the mountain city in advance to find out.

As a result, I almost died halfway through the road.

That's tired.

The city doesn't seem that steep from a distance, but when you walk to the city, you will find out that it's almost straight up and down.

Just those weak bodies of those old people are simply deadly to climb up.

Finally, Ma Erye carried Wen Tianxiang on his back, Wang Sheng carried Zhao Yurui on his back, and Yang Liangjie on his back. Zhao Wei was the most miserable, pulling one with one hand, Wen Tianxiang on his left hand, and Wang Yinglin on his right hand.

When he finally climbed to the top of the city and sat in front of the guardian gate, Zhao Wei could no longer help it. Niu Pan cursed: "Who is so stupid that he has come to play such a place!"

Mr. Ma couldn't even speak, so he threw Mr. Dieshan down and lay down and stopped moving.

"I, I know where Zhang Shuai's confidence comes from..."

Wang Sheng: "This, this...what the hell is this?"

Well, Zhang Jue has reason to be proud, because this city is simply unsolvable.

If God is besieged one day, he will definitely choose this place as the last city.

In other words, this is the way for God to leave for himself. This is the nightmare of siege and the perfect position for defending the city.

To put it in detail, Diaoyu Mountain is actually a flat-topped mountain composed of two-stairs.

The first-level mountain steps, reaching the river bank in the south, with three mudflats on the side, suddenly rise by dozens of feet in the gentle river beach terrain, like a giant mountain platform covering an area of ​​thousands of acres, surrounded by three rivers.

The outer wall of Diaoyu City is located on a cliff. Except for a small section of mountains and ponds in the northwest, you should not think about anything else. Not to mention people, cannons cannot be shot in.

Logically speaking, such a dangerous terrain should be steep and uneven in the city, right? It is not a good thing for the guard.

But, it's wrong!

After passing the first level of mountain platform, the mountain situation immediately became flat, and there were almost no concave and convex in the city. It was full of good fertile land, at least 2,000 acres.

After passing the outer city walls and farmland, the mountain suddenly rose for the second time, steeper and higher than the first-stage mountain terrace.

Above this cliff is the inner city wall, which is the core of Diaoyu City.

The mountain under the inner city wall has no slope at all, straight up and down, and there is no road to the mountain.

Unlike the city gates I understood in the past, the city gates of Diaoyu City are not parallel to the city wall, but stand between the city wall and the cliff. Directly opposite the cliff, there is a deep abyss below.

Zhao Wei and his friends stepped on the mountain and climbed the mountain, but they were temporary plank roads built with wooden boards.

Usually, wooden beams are used to wedge into the stone wall, and wooden boards are installed on them, and the plank road is removed during wartime.

Haha, the Mongolian Yuan has been fighting Diaoyu City for more than 30 years, but he has not even seen the city gate look like.

In the inner city, there are commander's offices, temples, schoolyards, grain processing workshops, gunpowder workshops, military equipment workshops, and even... palaces.

That was when Zhang Jue was still in Diaoyu City, he learned that the Song Dynasty's small court was in exile and was preparing to welcome the emperor into Shu.

All facilities are also connected to the inner side of the city wall, a racetrack paved with stone slabs, ensuring mobility during wartime.

There are also city guarding facilities such as forts and arrow towers on the city walls. The range not only covers the outside of Diaoyu City, but also blocks the surface of the Jialing River.

There are two thousand acres of fertile land in the outer city, and a war workshop consisting of the people.

What's even more terrible is that the outer city is divided into several areas and is also blocked by high walls.
