Zhong Yuan killed more than a thousand Jindan-level demon beasts in the demon beast jungle, and the mana of these demon beasts was equivalent to that of Jindan-level monks, but their physical bodies were many times stronger than those of Yuanying monks.

The Guiyuan Sword not only devours mana, but also devours flesh and blood essence, and the accumulated energy is quite huge.

This time, he spent more than a year in retreat, digesting the mana in the Guiyuan Sword, and his mana cultivation also increased a lot.

Then, it took a few more years to digest the energy of the flesh and blood of those demon beasts.

Those energies could not improve his mana cultivation, they could only strengthen his physical body.

Although his physical body is considered very strong among monks, it is not beyond the scope of human monks.

Now that he has absorbed the flesh and blood energy of so many demon beasts, his physical strength has reached an incredible height.

Since "Nine Transformations Return to Yuan Gong" has exercises for absorbing flesh and blood essences, it naturally also has exercises for refining these flesh and blood essences.

There is an exercise in it, called "Chaos Golden Body Technique", which is the art of refining the body.

With this energy, he was able to practice this exercise.

After spending a few years and exhausting those energies, he finally cultivated the Chaos Golden Body Technique to the point of Xiaocheng, and his physical body level was already comparable to that of a god-level demon.

It means that in the case of mana being banned, with only his physical body, he also has the ability to fight with a god-level demon.

This kind of physical strength is beyond the scope of human monks, and without the magic weapon that is beyond common sense, it is impossible for human monks to raise their physical bodies to this point.

With such a physical body, he has one more means to save his life in the future.

He spent five or six years in retreat, and when he came out, he found that Galaxy Science and Technology City was already very large-scale.

In the past five or six years, Qi Shengke and Ye Tang have become one with those people here.

Both of them are monks in the late Yuan Dynasty, and they can play a great role in the construction of Galaxy Science and Technology City.

The first oil well built by Galaxy Science and Technology City was assisted by the two of them in the past.

Because of the lack of relevant technical experience, many problems arose during the construction of the oil well, which were calmed down by the two of them with their powerful mana.

It was easy for monks to build oil wells with magic weapons, but oil had no effect on monks, and mortals could not use it.

If you want to really develop, you must build oil wells that can be used by mortals, and this will have the potential to change the world.

At this stage, there is no accumulation of technology, and they cannot do without the role of monks, but they must try their best to achieve the role of shielding spells in it, so that they can really obtain useful technology.

In the construction of the first oil well, the two of them made great efforts to follow up the whole process, and they did not dare to relax at all, and there would be problems almost every day, sometimes even many times a day.

If it weren't for their strong mana, not only would the oil well not be built, but I don't know how many skilled workers would have died.

After the successful construction of the first oil well, Galaxy Science and Technology City has accumulated a lot of technical experience, and when the second one is built, there will be many fewer problems.

The technology of these wells is very backward, and as for the first generation of technology on the earth, it is very primitive.

But their ability can only go so far, and they can still complete this step with the blessing of the monk's mana.

However, after taking this step, the road to development has opened up a lot.

Refining oil also requires technology, and they can only do it with the most primitive technology, but this has given them the ability to produce motor vehicles.

There are rubber trees, there is oil, and there are several models of cars, so it is not too much of a problem technically.

It took them half a year to make the first car, all handmade, according to the prototype of the Land Rover, to make a thing similar to a tractor, stupid and big, which can be used as its lifelong code name.

But it can drive!

This achievement makes those skilled workers proud.

With their own hands, they made this movable iron bump, and the speed is still very fast, what a proud achievement?

As for the ugly appearance, does that matter?

After they got a stupid big car with a speed of 30 kilometers per hour, the Galaxy Automobile Factory was officially established.

Their first task was not to produce cars, but to produce tractors for farming.

This technique is a little simpler, and it is also a little useful for ordinary people.

However, now they do not have the ability to produce on the assembly line, so they can only use manual hammering to produce tractors, each of which is unique.

There are still some monks to help, and some parts with high precision are not something that mortals can make by hand-forging, and the monks must use mana to help.

That's it, and they learned a lot.

If you want large-scale production, it is not something that can be achieved by the development of a certain sector, but must be developed by the entire science and technology city and the overall improvement of industrial technology.

Now it's time for them to gain experience, get the data, and lay the groundwork for future mass production.

Among the major departments of the Science and Technology City, the best achievement is the Galaxy Bicycle Factory.

After the rubber trees were planted, they began to collect rubber and make tires, and it didn't take long to master the art of making tires and the first bicycle was assembled.

Although this is also manual, but it is much simpler to make a bicycle by hand than to make a car, and in less than half a year, thousands of units were manufactured, and those skilled workers in Galaxy Science and Technology City are basically one per person.

The next step was to sell the bikes they produced to the rich kids of the mortal world.

The first point of sale they set was in the capital of Yuguo, and they got 1,000 vehicles, and they didn't sell them at first, but just hired a few young people to run around the streets on bicycles, which attracted the attention of a group of people.

That's something that has never appeared in the mortal world, although the monks have magic weapons that can go high and high, but mortals can't use it, but now bicycles can be used by mortals, and pedaling bicycles on the streets, needless to say, the degree of wind pulling.

After these young men had been pedaling their bicycles on the streets of the capital for a few days, many people came to them and asked what the moving iron wheel was, and where did it come from?

The answer they got was that it was a bicycle bought from the newly opened Galaxy Dealership, only 50 taels of silver each, and there was not much inventory, so they wanted to buy it as soon as possible.

There were many children of rich families in the capital, and a thousand bicycles were quickly snapped up.

Technology is starting to change life in this world.
