Some plants in nature are pollinated by flying insects such as honey, butterflies, and flies, and some are pollinated by wind. Pen? Interesting? Pavilion wWw. ｂiquge。 ｉｎfo

But sand melons and these creatures are different.

The desert on the other side of the lake is so harsh that there is no rain all year round, and flying insects such as bees and butterflies cannot survive there at all.

Not only that, but the environment in Zhao Village, just like indoors, usually even the wind rarely blows.

Therefore, in order to survive, a special way of survival has evolved between the sandmelon and its natural enemy, the melon badger.

That is, the sand gourd contains its melon powder in the whole plant, which will be quickly decomposed in the stomach and intestines of the melon badger, and then stimulate the excretory system of the melon badger to achieve the effect of being processed by the melon badger and then discharged.

This is also the reason why melon badgers will excrete while eating when they steal melons in the melon field. When the melon badger is excreted, the melon powder of the sand melon is decomposed.

And the pollination of sand melons is also different from other plants, it is pollinated by root absorption.

It is precisely for these reasons that the sand melon and the badger form a cycle of mutual growth.

To grow, the manure of the melon badger is needed. And the melon badger needs to eat sandmelon to absorb water. This cycle repeats, which is also the reason why there are always melon badgers in the melon fields of Zhao Village.

In the past, when Wang Hao didn't give Zhao Cun iron tools, the people of Zhao Village couldn't do anything with the melon badger with a thick carapace.

The two sides are evenly matched, and the melon badger will always be able to eat the melon, and at the same time excrete its feces to help pollinate the melon.

However, when the iron sword and the black sword spread to Zhao Village, although the number was scarce, Zhao Yun and the others had the capital to easily kill the melon badger.

In this way, in order to enjoy the sand melon exclusively, the people of Zhao Village will naturally not be polite to the melon badger.

When the melon badgers died in large numbers at the hands of the people of Zhao Village, the sand melons gradually lost their pollinators.

In this way, the sand melon naturally does not live long.

The reason why Wang Hao didn't help Zhao Cun solve this problem last time is mainly due to two reasons.

The first is that his strength was weak at that time, and in the face of the joint attack of the Jiulongshan Alliance, he had to ask for help from Zhao Village.

This secret was told to Zhao Village in advance, so who would pay attention to him Wang Hao at that time.

Of course, this is not the main reason, the main reason is that Wang Hao did not have the ability to help Zhao Cun solve this problem at that time.

The melon badger is a strange creature that evolved from oil.

They live in oil and eat oil. If they are left from oil for a long time, they will die like fish out of water.

Only when their bodies are dehydrated will they come ashore to eat sandmelons to replenish their water.

Therefore, the plan to help Zhao Village catch melon badgers and then raise them in captivity to fertilize the sand melons will not work.

The melon badger can't leave the oil for a long time, so the people of Zhao Village can't let the melon badger keep the melon badger in the oil lake.

But now, Wang Hao has a way to solve this problem.

With the help of systematic identification, he found several acidic plants in the Great Wilderness.

After these plants are boiled together to become mucus-like, and then dried to below zero with the help of winter temperatures, it will become the same stomach acid as the melon badger, enough to break down the sandmelon and separate the melon powder inside.

At that time, Zhao Village only needs to sprinkle these separated melon powder on the melon fields planted on the underground dark river, and the problem of sand melon cultivation can be solved.

Zhao Cun lent a helping hand to Wang Hao twice in a row, which made Wang Hao particularly pleased.

Therefore, when the envoy of Zhao Village came to borrow food from Wang Hao, Wang Hao naturally would not be stingy.

It happened that the wheat on the side of the Grand Canyon was ripe, and thirty carts full of wheat and ten carts of fish and meat followed Wang Hao on the road to support Zhao Village.

In the face of such a generous Wang Hao, the messenger from Zhao Village burst into tears of excitement, eager to repay Wang Hao's kindness.

Naturally, the importance of food in the Great Wilderness goes without saying. Especially in winter, food is the life of people in the great wilderness.

Originally, he thought that Wang Hao was just looking at the past and was willing to borrow food, it shouldn't be too much.

Borrow two or three cars at most.

But who knows, Wang Hao lent them forty carts of food all of a sudden.

With this food, their people will be able to survive this winter no matter what.

This time he went to Zhao Village, in addition to Wang Hao's twenty black-armored soldiers and a hundred savages pulling carts, he also brought ten Gollum.

Since the Gollum who met in the Grand Canyon came to Hwaseong, all the things related to construction in Hwaseong have been handed over to them to do.

Just like after the last war, they repaired the damaged houses in Hwaseong.

Later, the cellar where the food was stored in the autumn was dug and they built the floor wall with bricks.

There are also those expanded granaries, arsenals and other buildings, which are the fruits of their labor.

And since Wang Hao wants to bring them this time, he naturally wants to build a building on the side of Zhao Village.

No one can deny that oil is a very important resource. How could Wang Hao tolerate the fact that there is an oil field next to it, but he does not develop and utilize it.

In the past, it was a lack of manpower, lack of time, and inability to reach the capacity, which put the oil field in Zhaocun on hold.

And now, he has enough time and enough manpower, Wang Hao naturally wants to develop oil.

There are many ways to extract gasoline from oil, but for Wang Hao, the only way to achieve it at present is distillation.

Crude oil begins to decompose at 350 degrees Celsius, and this reaction process only takes a few seconds.

As long as he understands this truth, even if he puts crude oil in a cauldron and boils, Wang Hao can decompose gasoline.

It's just that the yield of this stupid method is too low, and the income is not proportional to the effort.

It is foreseeable that Hwaseong will need too many places for gasoline in the future.

In the future, when Hwaseong is upgraded to a third-level tribe, in the face of the overwhelming attack of monsters attacking the city, ordinary weapons will not be able to kill the enemy on a large scale.

Especially for those creatures that can fly, a small amount is fine, but once the number is large, there is no solution at all.

However, Hwaseong has already conquered the coal mines, and by the spring of next year, when the ground has thawed, the coal mines can be mined and iron smelting.

With iron, Wang Hao was able to make a flamethrower that could spray gasoline.

A weapon of mass destruction like a flamethrower could not be better used in the future to defend against the overwhelming attack of birds and bees.

Therefore, after careful consideration, Wang Hao finally decided to build a distillation base in Zhaocun to produce gasoline near the oil lake.

Petroleum distillation equipment already belongs to the third level of technology.

The Level 2 system is also capable of downloading Level 3 technology. It's just that downloading a level 3 technology requires three months of continuous accumulation of faith power.

However, the production line of petroleum distillation is divided into more than ten sections.

There are filling machines, heating furnaces, transmission equipment, etc., if you want to download all these things, Wang Hao will not use the system for four or five years.
