Chapter 157 Cultivating Wasteland

The land area of ​​Raging Breath Island is 578 square kilometers, which is equivalent to the area of ​​a small county in Yanhuang, even though it is an island.

The more prosperous northern area occupies an area of ​​about 400 square kilometers, while the remaining southern area, although smaller in area, still has more than 100 square kilometers. In this area, there are a large number of mining areas and rock areas. This type of landform is not suitable for planting.

But even so, the vast southern region still has areas suitable for growing crops.

That was the former rainforest growth area in the southern district, covering an area of ​​7 square kilometers, about ten thousand mu.

Li Tianran used the images transmitted back by the patrol-class radar sentry and saw a large gray area. The soil here was completely different from the soil in the mining area; it was soft and fertile. However, it was covered by a dense layer of dead trees and rotten leaves, the corpses of the former rainforest. Li Tianran had to deal with these things first.

"Reclaim all this area, and then build greenhouses, and the new planting area will be completed."

Soon, Li Tianran followed the patrol-class radar sentry to this wasteland. He squatted down and looked at the soil. Although it had also been radiated by toxins, the radiation-resistant crops had extremely tenacious vitality and could take root and sprout in this soil without any worries.

And the most important thing is... irrigation is relatively convenient.

Although ordinary crops cannot be irrigated with seawater, because the main component of plant cells is bound water, and this bound water mainly comes from fresh water. If high-concentration seawater is used for irrigation, the water in the plant cells will penetrate into the high-concentration seawater outside the cells, resulting in a large loss of water in the plant cells, causing the crops to dry up and die.

However, the cell structure of anti-radiation crops is completely different from that of ordinary crops. It will not wither due to water concentration. Even those difficult-to-absorb ions in seawater, such as salt, calcium, and magnesium, can be independently absorbed, circulated, and filtered!

Crops that can ignore radiation toxins cannot be harmed by seawater.

"Low-level crops are tenacious and have a very high survival rate. They are strong and resistant... but lv4 and above crops are too delicate. They not only have requirements for water quality, but also for soil. It seems that it is not yet realistic to promote the large-scale planting of advanced crops." Li Tianran stroked his chin and said to himself.

The survival rate of lv4 crops is very low. After Li Tianran's calculations, if he spends a lot of points to upgrade the land and purify the water source now, blindly pursuing the planting of advanced crops, the result will not be as profitable as temporarily planting low-level crops on a large scale.

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

This involves a probability problem.

Lv4 and above crop seeds have a survival rate, take ten percent as an example, it does not mean that planting one hundred trees will definitely survive ten trees.

Rather, each of these one hundred plants has only a ten percent chance of maturing. It is possible that all one hundred plants will eventually be wiped out, or it is possible that the plants that eventually survive will exceed ten.

This involves a very complicated formula. In short, after calculation, large-scale planting of advanced crops now can easily lead to a complete loss…

Li Tianran broke a few dead branches casually. Due to the radiation toxins, these rainforest plants had completely withered. In addition, the recent weather has been cold and dry, and these branches have long been dried out.

Pa!

Li Tianran lit a dead plant branch with a lighter.

Under these circumstances, a little fire caused a large area of ​​dead wood to burn.

Soon, billowing smoke rose into the sky above the island, and the dead wood in this rainforest was quickly swallowed by flames.

In the afternoon, Li Tianran brought in a whole team of agricultural machinery to turn over a large amount of plant ash and soil. This was originally land where plants grew, so it was not too difficult to reclaim. In just one afternoon, two thousand mu of planting fields were created. At this rate, the task of reclaiming tens of thousands of mu of wasteland will be completed in at most three days.

But Li Tianran knew that wasteland reclamation was just the beginning, and the next step of building a large number of insulated greenhouses was the highlight.

Lv2 anti-radiation crops have strong vitality, but they are difficult to resist severe cold and wind, and need to be kept warm. Although Li Tianran noticed that the recent temperature has risen a little, it has not yet reached the point where crops can grow freely.

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

Now is the forty-second day after the second world change, and there are still eighteen days before the next Doomsday!

…

In the evening, Li Tianran came to the area where the warship was being refitted again. He had not rested for a moment all afternoon.

In the distance, a beast king showed its head on the sea surface, tumbling and diving back into the water.

These were the beast kings that Li Tianran had captured at the beginning. They had contributed to the plan to seize the warship. Li Tianran did not keep them in captivity inside the farm, but let them be scattered in the sea area around Raging Breath Island.

However, as long as they exceed the range specified by Li Tianran, the sensors in their bodies will be triggered, detonating the bombs hidden in their fatal flaws.

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

At this time, Xiao Hei and Bai Mao were stepping on the back of a white shark beast king, playing in the water on the sea surface illuminated by the last ray of daylight. The dog and cat were playing extremely happily, which surprised Li Tianran a little.

"Too much Titanic, huh..." Li Tianran watched Xiao Hei and Bai Mao playing intimately and cursed maliciously, "Be careful 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!"

Li Tianran's sudden roar was certainly not crazy. In his consciousness, he sensed that the bomb in the body of a beast king in the sea area ahead had exploded. Then, a layer of blood slowly floated on the sea...

But the positioning information of that beast king had never left the range specified by Li Tianran. It stands to reason that the bomb should not have exploded at all!

Unless that beast king tried to remove the bomb in its body and instead triggered the activation condition, but this possibility is very small, because Li Tianran had let the beast kings see with their own eyes how he used this bomb to kill beast kings who tried to remove the bomb...

Then there is only one possibility left.

Something underwater attacked the beast king. During the attack, the location where the bomb was located was hit and the bomb was activated!
