In the previous life, the earth was convenient for transportation and the flow of cars was endless. The sacrificial world I am in now is a different world similar to the ancient society, and it is relatively backward in terms of transportation and information transmission.

Now, the Tiannan Tribes have officially entered the East Continent of the Free Realm, and in order to build the East Continent, not only must roads be built, but also the means of transportation must be updated, and because the Free Realm has a wider sea area than the Zhijing Earth Boundary, the development of the third generation of warships must also be accelerated.

However, compared to the creation of land vehicles, at least the ship attendants have accumulated enough valuable experience in the development of warships, so there is no need for Tian Tiannan to ask, as long as they continue to meet their needs.

At the beginning, Tian Tiannan wanted to get out the trucks from his previous life in the sacrificial world, and it was really good to use them to transport them.

After that, he went to great lengths to find all kinds of materials, and the vehicle he made was indeed very ordinary, and because it was completely amateurish, even with the assistance of the system, it saved him a lot of steps.

However, it is important to know that in this world there is simply no market for such a truck, and it is too easy to destroy it.

"Tiannan, why don't we load the Tiannan cannon onto the truck!" After months of study, I finally came up with a finished product, but it was not satisfactory, so inadvertently, a small word woke up Tian Tiannan.

"Hahaha, why didn't I expect that, sure enough, baby, it's so right to let you come!" Tian Tiannan, who was woken up by a word, excitedly picked up the two wives, and immediately rewarded them with a long kiss despite the fact that the rest of the girls were still present.

Yes, in this world, war is as common as eating, and since he can think of bringing the thermal weapons of his previous life to this world, why would he forget about the existence of tanks and armored vehicles?

Before that, the problem that Tian Tiannan needs to solve is the problem of power.

Ordinary trucks can also use the vehicle version of the warship engine to fool around, but the tonnage of tanks and armored vehicles, his strange warship engine is a little inadequate, if the tank is built as big as the second-generation warship, it is simply a joke.

So, at this time, Tian Tiannan needs to ask for help from the system, since he can even get Tiannan cannons and guns, it should be no problem for him to tinker out the real engine according to his sporadic memories, it's a big deal, he will pay more money.

"Five hundred million?"

"Okay, deal!" After some communication, as he expected, the system has the ability to help Tian Tiannan solve the problem of the engine, and the price is also acceptable to Tian Tiannan, although it is still so dark!

······

"Tiannan, what is this ugly guy?" Five days later, in the laboratory, a group of people were talking about something they had never seen before, and Xiao Xiaoxiao, who couldn't help it, asked directly.

"Tiannan, this should be the engine of the new car you mentioned earlier, right? It looks a bit like a warship engine! Yuxiang also spoke.

"Our Xiangxiang is smart, I'll tell you..." Hugging Yuxiang, Tian Tiannan began to introduce.

Different from Tian Tiannan's strange engine, the system shot, the principle and structure of the engine in front of it are basically the same as the orthodox engine, but at the same time, because it is from the hands of the system, this engine also has the characteristics of sacrificial equipment, and its power source is sacrificial power!

Because Tian Tiannan needed to use it to make money, he asked the system to make two engines, or two levels of engines.

The low-profile version is a burning sacrificial point, that is, the liquid sacrificial power that can only be stored through a bronze container, while the high-profile version burns a sacrificial fountain in a liquid state under natural circumstances.

The low-profile version of the engine can only support small and medium-sized armored vehicles, because it can't afford too much tossing, so don't think about it for tanks, only the high-profile version can be used on tanks and heavy armored vehicles.

In this way, products for sale and products for personal use can be well distinguished.

The problem of the engine is solved, and the next thing is the car body, regarding the materials used to build the car body, Tian Tiannan has his eyes on the poisons in the trial city, who makes the armor on these guys stronger than the other.

"System, if you want to completely simulate a spider to make a kind of chariot, will it work?" During this period, Tian Tiannan had such a rather sci-fi idea in his mind, and formally asked the system.

And the answer he got was naturally no pressure, but the amount of sacrificial source crystals to be spent was a bit terrifying, if all of them were manufactured by the system, the research and development cost would be 50 billion sacrificial source crystals, and the cost of each one would not be less than 10 million.

But spending a lot of money, it is naturally worth the money, this kind of sci-fi chariot, the combat power will be comparable to the fifth-stage warriors, and it is not a problem to confront the priest head-on.

But now, even if he has so much family property, it is impossible for Tian Tiannan to come up with as much as 50 billion working capital to develop a chariot at one time, otherwise, the Tiannan tribe will go bankrupt, and millions of tribesmen will have to bury him in minutes.

Now that the Tiannan Empire has a big business, just the daily money for buying a life is enough to collapse a small primary city, and the entire tribe spends millions of dollars every day, so he doesn't dare to spend too much money at all.

Helpless, Tian Tiannan could only temporarily extinguish this unrealistic idea, and instead concentrated on tinkering with his armored vehicles and tanks.

In order to increase the combat power of the armored car, so as to make it more selling, Tian Tiannan referred to the warship and installed the amplification altar on the armored car, so that as long as there is a priest sitting in it, the armored car will also have strong combat power.

The preparation conditions have all been in place, and it took Tian Tiannan three months to finally make a model of the armored car body and a 1:1 car, and then, he only needs to hand them over to the equipment attendants to eat thoroughly, and they can be mass-produced.

The armored car is completed here, and the more troublesome thing is the tank, because it is more difficult to tinker with the artillery on the tank, and if you let the system shoot, you have to stuff a lot of money.

As the core and most important part of the tank in addition to the engine, the asking price of the system for the gun is not low, which makes Tian Tiannan a little unbearable, and every time the system presses his bottom line, which makes him very annoyed.

Simply, the only thing he doesn't lack now is time, and he is about to be promoted to the chief priest, and his lifespan will exceed a thousand years.

So, he could afford to spend that few years researching a powerful piece of equipment.

In addition, he is not alone, he now has hundreds of thousands of logistics attendants behind him, compared to the price of the system, Tian Tiannan can get a large number of level 20 to 30 logistics attendants to work for him with tens of millions, and a level 30 logistics attendant research and development team of 100 people is enough to shorten his research time by half.
