Doomsday Super Farm

Kuangxi Island covers an area of ​​578 square kilometers. Although it is an island, it is equivalent to the area of ​​a small county in Yanhuang.

Among them, the more prosperous North District occupies an area of ​​about 400 square kilometers, while the remaining South District, although small, covers more than 100 square kilometers. Within this area, there are a large number of mining areas and rock formation areas. This kind of landform

None of them can be planted.

But even so, there are still areas suitable for growing crops in the huge Southern District.

It was the rainforest growth zone in the southern district in the past, covering an area of ​​about 7 square kilometers, about 10,000 acres.

Li Tianran used the footage transmitted back by the patrol-level radar guard to see a large area of ​​gray. The soil here was completely different from the soil in the mining area. It was soft and fertile, but it was covered with a dense mass of dead trees and rotten leaves.

They were the corpses of people who died in the rainforest in the past. Li Tianran had to get rid of these things first.

"Cultivation of this entire area and erecting greenhouses will complete the new planting area."

Soon, Li Tianran followed the patrol-level radar guard to this wasteland. He squatted down and took a look at the soil. Although it was also radiated by toxins, the vitality of radiation-level crops was extremely tenacious and could take root in this soil.

There is no need to worry about germination.

And the most important thing is...it is easier to irrigate.

Although ordinary crops cannot be irrigated with seawater, because the main component of plant cells is bound water, and the main source of this bound water is fresh water. If high-concentration seawater is used for irrigation, the water inside the plant cells will penetrate into the high-concentration seawater outside the cells.

, resulting in a large amount of water loss in plant cells, causing crops to wither and die.

However, the cell structure of radiation-proof crops is completely different from that of ordinary crops. They will not die due to the concentration of water sources at all. Even the large amounts of salt, calcium, magnesium and other ions in seawater that are difficult to absorb can be absorbed and circulated independently.

filter!

Even crops that can ignore radiation toxins cannot be harmed by sea water.

"Low-level crops have strong vitality, extremely high survival rate, and are strong and resistant to damage... But crops above level 4 are too delicate. They not only have requirements for water quality, but also for soil. It seems that we want to promote the planting of high-level crops on a large scale.

It's not realistic yet." Li Tianran touched his chin and said secretly.

The survival rate of lv4 crops is very low. According to Li Tianran's calculations, if you spend a lot of points to upgrade land and purify water sources, and blindly pursue planting high-level crops, the result will be more profitable than temporarily planting low-level crops in a large area.

At least low-level crops can guarantee a survival rate and maintain capital, while high-level crops have a survival rate limit. It is possible that Li Tianran spent a lot of points to buy high-level seeds and planted tens of thousands of acres of high-level crops, but in the end they all died...

This involves a probability issue.

Crop seeds above level 4 have a survival rate, let's take 10% as an example. It doesn't mean that if you plant a hundred trees, you will definitely be able to survive ten.

Rather, each of these one hundred plants has only a 10% chance of reaching maturity. It is possible that all one hundred plants will eventually be wiped out, or it is possible that more than ten plants will survive in the end.

This involves a very complicated formula. In short, after calculation, it is easy to lose money by planting high-end crops on a large scale...

Li Tianran casually broke off a few dead branches. Due to radiation toxins, these rainforest plants have completely withered. In addition, the recent cold and dry weather has meant that these branches have long since dried up.

Snap!

Li Tianran lit a dead branch of a plant with a lighter.

In this case, a little fire caused a large piece of dead wood to burn.

Soon, billowing smoke rose over the island, and the dead trees in the rain forest were quickly engulfed in flames.

In the afternoon, Li Tianran brought in a whole team of agricultural machinery and turned over a large amount of plant ash and soil. This was once the land where plants grew, and it was not too difficult to cultivate it. In a whole afternoon, two thousand acres of planting land were covered.

It was done. According to this progress, the reclamation task of tens of thousands of acres of wasteland will be completed in three days at most.

But Li Tianran knew that the reclamation of wasteland was only the beginning, and the next step was to build a large number of insulated greenhouses.

Level 2 radiation-proof crops have strong vitality, but they are unable to withstand the severe cold and wind and need to be kept warm. Although Li Tianran noticed that the temperature has risen somewhat recently, it is not yet to the point where the crops can grow freely.

Li Tianran is no stranger to building vegetable greenhouses, but a project of tens of thousands of acres is a huge challenge for him. Even with the help of adult warriors, it will take a long time for Li Tianran to complete the entire project of ten thousand acres.

It is now the forty-second day after the second world mutation, and there are still eighteen days before the next era of destruction arrives!

…

In the evening, Li Tianran came to the warship refitting area again. He did not rest for a whole afternoon.

On the sea in the distance, a beast king emerged from the water, tumbling and diving into the water again.

These are the beast kings that Li Tianran captured at the beginning. In the plan to seize the warship, they can be regarded as having made a contribution. Li Tianran did not keep them in captivity inside the farm, but let them disperse in the sea area near Kuangxi Island, because

The artificial lake on the farm really cannot accommodate these big things. Li Tianran also wants to raise seaside products. If these beast kings are kept in captivity on the farm, they may eat up all the seafood in the artificial lake in one day...

But as long as they exceed the range specified by Li Tianran, the sensors in their bodies will trigger, detonating bombs hidden in the fatal flaws of their bodies.

Under the threat of death, none of these extremely intelligent beast kings dared to try to escape.

At this time, Xiao Hei and the white cat stepped on the back of a white shark king and played paddling on the sea under the last ray of skylight. The dog and the cat were playing so excitedly that Li Tianran was a little surprised.

"You've seen too much Titanic..." Li Tianran watched the little black and white cats playing intimately, and cursed maliciously: "Be careful of falling into the water!"

As soon as Li Tianran finished speaking, his expression suddenly changed and he roared in the distance: "Xiao Hei, come back quickly!"

Of course, Li Tianran was not crazy when he roared suddenly. In his consciousness, he noticed that the bomb in the body of a beast king exploded in the sea ahead, and then, a layer of blood slowly floated on the sea...

But the positioning information of the beast king never left the range specified by Li Tianran. Logically speaking, the bomb should not explode at all!

Unless the beast king tried to remove the bomb from his body, but triggered the activation condition, but this may be very small, because Li Tianran once let the beast kings see with their own eyes that he used this kind of bomb to kill the beast king who tried to remove the bomb.

scene……

Then there is only one possibility left.

Something under the sea attacked the beast king. During the attack, the location of the bomb was hit and the bomb was activated!
