In April of the 15th year of the reign of Qiansheng, the eight major countries signed an agreement and cooperated to establish the 'Kean Oil Company'.

With the agreement reached, the troops began to withdraw from the Kean area, and while calm was about to return, the Kan area gradually became unstable.

In May of the fifteenth year of the reign of Qiansheng, with the withdrawal of all the military troops of various countries, several large tribes and some opposition forces in the local area of Kean began to make trouble, and they did not say that they would engage in large-scale military resistance at the beginning, which was unrealistic, after all, although the armed forces of various countries had withdrawn, the garrison of the Gafians was still there.

The opposition was not stupid, and naturally it was impossible to hit a stone with an egg in a stupid way, but adopted the method of small-scale attacks, attacking the outposts, transport convoys, and grassroots government facilities of the Gafia Army and the Kenn Defense Army.

Not only that, but the rebels also began to attack the facilities of the Ken Oil Company, and the local opposition issued a manifesto, saying that anyone who was willing to work for a foreign oil company and betrayed the interests of the Ken Oil Company was a traitor to the Kenn people, and everyone was punished.

For a time, the business of the newly established Kean Oil Company came to a standstill.

This has naturally attracted the attention of the major powers, but the supporters behind these opposition are these big countries, even if most of those radical opposition are instigated by Daheng people behind the scenes, but in fact, there are still big countries such as Krull.

Without the support of the Seven Great Powers, it would have been possible for so many rebels to appear in the Ken area in just a few months, and all of them were fully equipped with the most advanced rear-loading guns.

Well, what the hell, when the troops arrived in the Kenn area, they brought a lot of weapons and ammunition, and when they withdrew, they left, but a lot of equipment flowed into the hands of the opposition through secret channels.

Now in the Kenn region, it's Gafia, the Six Kingdoms, the Great Heng Empire, and one more Lidji is constantly making trouble, and it won't be long before Kenn is completely messed up.

In this case, it is not so easy for oil to be extracted smoothly.

After learning that the development of the situation in the Ken region was still under the control of the empire, Lin Ziran was also a little relieved.

He didn't expect to be able to control the situation on the ground and disrupt local production for a long time, but a few years would be enough.

With buffers in recent years, it is enough to complete more layouts by yourself.

In a few years, the new generation of warships of the Great Heng Empire will be commissioned one after another and gradually form a scale, and then it will be the time for the Great Heng Empire's navy to dominate the endless sea.

With a strong navy in hand, what can't you do?

What the Krull Kingdom has done in the past few decades, the Great Heng Empire can also do, plundering profits on a global scale.

Of course, there is also a need for the necessary back-up, such as ensuring that in times of war, you can cut off the export of Kean oil and cut off the oil that rival countries receive from Kean.

The best way to do this is to directly attack Ken in wartime, take control of the Ken Field, and destroy the Ken Field, so it is very necessary to deploy a certain number of army units at the Beauwa Military Base for a long time.

However, if you rely solely on army units, it is actually too difficult, and the Gafia Empire is not muddy, their army size is still very large, and the army size needed to win will be very large, which will pose a huge challenge to logistics support.

Therefore, the army directly marches into the oil fields and destroys the oil fields, which can only be used as an alternative.

In fact, the best way is to use the air force to bomb directly, from the Bowa military base to the Kenn fir area, the air distance is only more than 300 kilometers.

However, in these years, the internal combustion engine is not mature, and the aircraft is even less visible.

Without the Air Force, then the naval blockade will have to be relied upon.

The Empire needed to deploy a fleet strong enough at the Beauva military base to ensure a complete blockade of the coastal areas of Kean in time of war, so that not a single oil tanker could get out.

This difficulty is also very huge, and this is the Gafians, although their navy is not good now, but it will be a problem after the strength is restored in a few years.

And even more important are the Krulls!

However, there is an archipelago not far away as a military base, and if a fleet is deployed on it, it is enough to effectively cover the safety of the coast of Kean.

At this time, it is natural to compete with the scale and performance of the battleship!

In addition to these conventional means, Lin Ziran is also preparing for the Navy to develop advanced submarines.

It is not the steam engine powered steam submarines that are being developed by the navies of various countries, nor the so-called all-electric propulsion submarines powered by batteries, which have become popular in recent years.

Lin Ziran asked the navy to develop submarines with internal combustion engines and batteries, and dual power systems.

Submarines are propelled by batteries when they are underwater, and when they surface, they are propelled by internal combustion engines, while the batteries are charged.

Although the development of internal combustion engines is not very mature now, it is still available, and it has been gradually applied to industrial production, agricultural machinery and passenger cars.

Not only gasoline engines, Daheng Empire is also developing oil extractors at the same time, but the research and development is a little behind, and after a few years, after the development of marine diesel engines is more mature, it can be installed on ships and used as submarine power.

After the advanced submarine is developed, it will be combined with the thermodynamic torpedo under development, and the surface fleet will be able to better block the coast of Ken.

As long as the export of Kean oil is cut off in wartime, the amount of oil produced by other countries in other places, even if it is all used as naval oil, is estimated to be not enough for the fleet to run a few times.

Not to mention that the army will also need a lot of fuel in the future, and the air force that will emerge in the future will also need a lot of fuel.

When the time comes, will these countries follow up or not?

It is naturally impossible not to follow up, and when the Daheng people used tanks and planes, they didn't have them, wouldn't it be the end......

But in the follow-up, the performance of the equipment is there, but the fuel required for these equipment needs to be imported, and there is a great risk of being cut off from the oil supply by the Daheng Empire.

However, not all countries are counting on external oil supply, but after the Kyle Empire has searched the territory and not found even a drop of oil, in addition to looking for oil around the world like the Krull Kingdom, it has been immersed in the study of coal-to-oil technology for several years.

In fact, the coal-to-oil technology is not new, scientists converted kerosene from coal decades ago, but it has not been developed much, and it has not changed until the last few years.
