Bei Tang Yu didn't plan to join the Great Xue Empire before, after all, Bei Tang Yu didn't like to be bound, but thinking about his 3 disciples, plus he had to live in this world for 10 years, he reluctantly agreed.

Becoming the worship of the Great Xue Empire, in fact, there is nothing to do, unless there is something special and important, otherwise the empire will not easily mobilize the power of worship.

And Beitang Yu's arrival is not just for worship, but for fun, in addition to cultivation, there must be something to do, otherwise Beitang Yu will not accept 3 disciples.

"Are you saying true?

Beitang Yu asked the emperor for those black oils, it can be said that they don't know what those oils are, but under Beitang Yu's pictures and texts, even if they don't know what oil is, the emperor will let people find it.

A huge empire, once mobilized, is naturally very strong, especially this kind of feudal empire, as soon as the emperor's order came out, there were countless people working for him.

The search for oil didn't bother Beitang Yu at all, but the oil still had to be processed, so Beitang Yu naturally had to build an oil refinery by himself.

Although the oil has not yet been obtained, it is no problem for Beitang Yu to come and get some oil with the power of the Great Xue Empire.

And the construction of the oil refinery was also built little by little by relying on the construction method provided by the White Queen, but it was still a little worse industrially, and in the end, it was built little by little by relying on Beitang Yu's own hands.

The refinery was built in a relatively inhospitable area, and there were no people here, so no one knew that there was such a refinery, and even those who knew about it did not know what it did.

And after the people sent out by the Emperor to get all the oil back, then the next step is naturally to refine the oil.

As long as Beitang Yu has fuel, other products can only be stored first, and let the craftsmen of the Daxue Empire develop it by themselves, and the fuel is solved, so it is natural to build an airplane.

The fighter is Beitangyu's first choice, and it is also the kind of Kun-style fighter that was obtained from S.H.I.E.L.D., but thinking about the high-tech content of the Kun-style fighter, Beitangyu first got a combat helicopter developed by the umbrella company.

In addition to the above weapon system, the combat helicopter of the umbrella company can be used as a troop carrier to transport soldiers, and the creation of such a combat helicopter is also done by Beitang Yu himself, with a large number of craftsmen busy.

Beitang Yu, the new worshipper, had a good time, and naturally consumed a lot of money in the empire, although this money was nothing, but it made the head of the household feel that Beitang Yu was wasting the empire's financial resources.

Beitang Yu just came to the Great Xue Empire to become an enshrinement, although the worship status is high, but no one is enshrined like this, if it is said that the worship needs any natural treasures or elixirs, even if it costs more money, it doesn't matter if it costs ten times more than Bei Tang Yu, because the strength of the worship is improved, it is also for the empire.

But Beitang Yu is both an oil refinery and an airport, and the things he does are all things that no one else can understand, which makes Tobe Shangshu want to sue, but thinking about Bei Tangyu's identity, Tobe Shangshu doesn't dare to say anything, so he can only buy a panacea for cultivation for Beitang Yu.

Beitang Yu has been busy since he came to the imperial capital, and even the three disciples can't pay attention to it, so Tang Lao Dao doesn't know why Bei Tangyu is so diligent.

Originally, Tang Laodao also wanted Beitang Yu to learn from the top three worshippers in the Great Xue Empire to see what Beitang Yu's strength was, and also let the worshippers in the imperial capital know about Beitang Yu, but seeing that Beitang Yu was busy like this, there was no way to arrange it.

And several worshippers in the imperial capital, although they heard that Beitang Yu was arrogant in Dayan City, and claimed to be the number one master in the world, although they had Tang Lao Dao as a guarantee, and at the same time, they all felt that Beitang Yu really had the breath of a great martial arts master, so they didn't pay attention to it.

After being busy for a while, Bei Tang Yu finally made the Kun fighter, the craftsmanship of the Kun fighter is really not something that a group of craftsmen from the feudal empire can make, there is no Bei Tang Yu's drawings, there are no accessories forged by Bei Tang Yu himself, relying on these craftsmen alone, they don't know what to do with the Kun fighter at all.

And looking at this black Kun fighter on the airport, these craftsmen are actually very confused, although they are busy with Bei Tang Yu, but they are busy until now, they actually don't know what this Kun fighter built by Bei Tang Yu is.

It looks like the Kun fighter is quite big, but what's the use of being big?

Although the Kun fighter had wheels, how many horses did it have to be used to draw a horse for such a large size? And what kind of rubber, glass, and other crafts made it made made many craftsmen dizzy.

"My lord, this Kun ...... What is the Ekun type machine used for?" asked the craftsman head cautiously to Beitang Yu.

This is the first time that the craftsman old man has made something that even he doesn't know, looking at the black Kun fighter, although the lines are very tall and tall, and he has also learned a lot of craftsmanship from it, but when the Kun fighter comes out, he really didn't figure out what the Kun fighter is.

"Wait, I'll test it out. Beitang Yu said to the craftsmen, and then asked them to withdraw a certain distance.

Beitang Yu got on the Kun fighter and began to operate on the Kun fighter, and the Kun fighter created with the technology of S.H.I.E.L.D. is naturally exactly the same, even if it took a long time on some processes, but under the focus of Bei Tang Yu, no tofu scum project was made.

However, it is still very laborious to manufacture Kun fighters in this world, and the backwardness of industrial technology makes the construction of Kun fighters very difficult, that is, some accessories have to be built by Bei Tangyu himself.

Beitang Yu skillfully operated the Kun fighter, and with the start of the Kun fighter, the leaders of the craftsmen at the edge of the airport and many craftsmen looked at the Kun fighter that had taken off slowly.

"Oh my God, that big iron bird actually flew!!"

The head of the craftsmen and many craftsmen were really stunned, the appearance of the Kun fighter was somewhat similar to that of a bird, but it was all made of iron, and with their knowledge, they didn't understand how the Kun fighter flew.
