"Everyone else has no money to spend, but to me, it has become rich and nowhere to spend? How does it feel like it's a little inflated! ~”

Li Wenbin couldn't laugh or cry.

It's not that he doesn't want to upgrade the Doomsday Bastion, it's that he can't. Because in order to upgrade the fortress to level three, three conditions need to be met.

One, the population of a level 2 fortress reaches thirty percent of the upper limit.

Second, the evolution level of the city lord has reached the second order.

Third, energy 10,000.

In addition to energy, the other two really need time.

The upper limit of the population of the second-level fortress is 10,000 people, and 30 percent is about 3,000 people. And now, including him and Yun Meng, the population of the fortress is only more than eight hundred, and it will take a long time to reach the required population for upgrading.

Of course, if Li Wenbin wants to, there are two ways to shorten this time.

The first, summon infantry and even farmers in large numbers.

The second, allowing other human survivors to join the city.

Li Wenbin could not have chosen these two methods.

Although the time is shortened by summoning a large number of infantry and farmers, the cost is that the fighting strength of the fortress is seriously insufficient, which is absolutely unusable in this cruel last days.

As for recruiting other survivors, Li Wenbin had an idea, but he quickly vetoed it. He had no intention of recruiting other survivors into his fortress other than those who were truly approved of him.

Whether it's a careful eye, or a sense of distress that is too serious, that's what he intended.

In this way, Li Wenbin could only summon spear and shield warriors and archers step by step, and slowly gather the required number of upgrades.

According to the calculation that one archer and one spear and shield warrior can be produced in half an hour, it will take about a month to reach a population of about 3,000.

After a month, Li Wenbin felt that there was no big problem.

At present, the combat power of a single spear and shield warrior or archer is no worse than that of an ordinary first-order early enhancer, and two to four can be compared to ordinary evolutionaries, and if they form a battle formation under the leadership of the captain, the power is even more powerful.

Such strength is enough to deal with the vast majority of enemies.

According to the experience of the previous life, the mutant creature with the fastest evolution speed could not break through the second-order barrier within a month, while the speed of humans was even slower.

And with the increase of time, the number of spear and shield warriors and archers will increase, and when the time comes, even if there are a few perverted guys, Li Wenbin will be sure to deal with them.

Born again, he has absolute confidence to be at the forefront of the evolutionary frenzy.

Since it is not possible to increase the combat arms for the time being, what Li Wenbin can do is to appropriately add some buildings.

For example, farmland and orchards.

Relying on the collection of resources is only a temporary measure, no matter how much food is stored, there will be a time when it is exhausted, and the only real way to solve the food problem is to establish a self-sufficient production line.

Farmland is naturally indispensable.

As for the orchard, it's the icing on the cake, and it's good to satisfy your cravings once in a while.

As soon as he thought of it, Li Wenbin immediately left the city lord's hall and came to the outer city area, directly dividing a vacant land for building farmland.

——

Construction: Farmland*1

——

The order fell, and the ground, which was originally a bluestone floor, quickly turned into a real farmland.

According to Li Wenbin's own experience of planting rice, as long as the cultivated seedlings are planted well, there will be nothing else.

Convenient.

Even if Li Wenbin expected it, he was still suppressed by this terrifying efficiency.

——

(Farmland construction completed.) ）

——

When everything was completed, a mechanical prompt sound immediately sounded in Li Wenbin's mind.

He immediately brought up the corresponding interface and began to check.

——

Farmland*1 (unsown)

Main crops: rice, wheat

Maturation cycle: 30 days

Estimated yield: 30,000 kg of rice and 15,000 kg of wheat

(There is no seasonal restriction on planting in the field, but you can only plant up to five seasons in a year.)

——

'Produced by the fortress, it must be a high-quality product'.

Li Wenbin once again felt the meaning of this sentence.

The farmland of the Doomsday Fortress has a square with a side length of 100 meters, so a piece of farmland covers an area of 100*100, that is, 10,000 square meters.

10,000 square meters, equivalent to one hectare, according to the acre, there are 100 acres, in exchange for the often said acres, it is 15 acres.

Before the end of the world, the yield of hybrid rice per mu was about 700 to 900 kilograms, which was slightly different according to the different climatic and soil conditions of the region.

In 2016, Mr. Yuan and his team set a world record of an average yield of 1149.02 kilograms per mu.

This is a very remarkable number, before the end of the world, that shocked the whole world.

However, compared to the farmland of the Doomsday Fortress, even super rice is much inferior.

A piece of farmland in the Doomsday Fortress has 15 acres and an estimated yield of 30,000 kilograms, or an average of 2,000 kilograms per acre.

Not only is it almost twice as much yield as super rice, but it is even more crushing in terms of maturity cycle.

30 days per season, 5 crops can be planted in a year, and there is no seasonal limit, and the fantastic data, if placed before the end of the world, will definitely cause a sensation around the world.

If it is before the end of the world, based on these alone, Li Wenbin can get those Nobel Prizes or something.

And in the last days when food is extremely scarce, with farmland, Li Wenbin can do more.

30,000 kilograms in one season, five seasons a year, this piece of farmland alone, in a year, can produce 150,000 kilograms.

With 150,000 kilograms of grain, Li Wenbin didn't know how many people would be able to eat it for a long time, but he knew that even if the population of the second-level fortress was full, the output of this piece of farmland could easily feed everyone.

Originally, he had planned to build a few more farmlands, but at this moment he changed his mind, and after building another piece of farmland, he did not increase it.

Two pieces of farmland can produce 300,000 kilograms of grain in one Chinese New Year's Eve, which is enough.

As long as he survives the last month, the food crisis will never exist in his city.

When the two farmlands were completed, Li Wenbin did not delay at all, and immediately asked the farmer to convert dozens of kilograms of rice seeds, and found Yunmeng and asked her to find someone to be responsible.

Yunmeng's work efficiency was extremely high, and after a while, he brought a few survivors who looked like the banker's man to Li Wenbin.

Li Wenbin didn't talk nonsense, and directly handed over the rice seeds that had just been converted to these people.

"We will start raising seedlings immediately, and in the shortest possible time, we will plant all these two fields with rice."

Several trembling survivors were at a loss at first, but soon understood what Li Wenbin meant.
