“…… Scold...... Ahh Is this the regimental commander infected with a cold? Or is there someone behind my back who is speaking ill of me? ”

Wang Qiu, who was far away on the beach of Hope Harbor, suddenly felt a chill in his spine and an itchy nose for some reason, and suddenly let out a loud sneeze.

He took out a tissue, wiped his nose, and just wanted to throw it away, but was dragged to the edge of the fire by Wen Desi, who looked nervous.

“…… Burn it off and disinfect it right away! I don't want another big flu in the country! ”

At the urging of Wen Desi, Wang Qiu had no choice but to throw the paper towel that had wiped his snot into the fire and burn it, while muttering in his mouth, "...... Alas, the Mexican highlands, which were still at an altitude of 2,200 meters the day before yesterday, have returned to the Pacific beach with coconut groves and blue seas today, and the climate change is really violent...... It feels like I've come from the Qinghai-Tibet Plateau to Hainan Island in the blink of an eye......"

Such unimportant words made the "Archangel" Wen Desi roll his eyes when he heard it.

“…… Hey, Senior Brother Wang Qiu, this may only be a day in the past for you, but for me, it's a full month of trekking on a bumpy road that only a goat can jump over! There was also a landslide in the middle and almost rolled down the mountain...... Don't continue to show your happiness in front of me, okay? ”

He had a stinking haggard black face with a scruffy beard, and he was full of resentment, "...... When you have to travel a long way deep into the enemy's territory, you hide on the other side of the wormhole, and I am the only one who treks over the mountains and mountains, and when I reach the ground exhausted, you come out leisurely and wander twice to see the scenery. When it was time to leave, I was the only one left on the road...... This also makes people psychologically unbalanced! ”

“…… Don't talk about yourself so pitifully! Literary director, isn't there hundreds of women's army to accompany you on your trip? ”

Wang Qiu smiled and patted him on the shoulder, "...... Besides, if I hadn't traveled through time and space again and again, where would I have gotten you a machine? ”

- At this time, on the beach outside Port Hope, a swarthy steam engine is standing. The rows of thick and heavy cast iron parts, as well as the rusty fuselage, all give people a sense of the vicissitudes of the times.

This is an old-fashioned pot camel machine that Professor Yang turned out of the university's unknown hole and produced in the 50s of the last century.

The so-called pot camel machine is to install the steam engine directly on the boiler, so it is named the pot camel machine. This machine is bulky and flawed, but one of the biggest benefits is that it can use low-quality fuel, or more specifically, coal!

Whether it is peat and lignite, which have a very low combustion value of low-quality coal, as well as common dry firewood, straw in rural areas, or even dry cow dung of nomadic herders, as long as the water content does not exceed 40 percent, it can be used as fuel for pot camel machines.

Therefore, although the pot camel machine has many shortcomings, but in the early days of the founding of the People's Republic of China, when China was still extremely short of oil, it still became an important mechanical power source, and it was widely used in rural areas, whether it was power generation, pumping or rice milling, it was inseparable from this pot camel machine. It was not until the Daqing Oilfield was put into production that the camel engine and the gas engine were gradually eliminated by the diesel engine.

At that time, most of the eliminated pot camel machines were naturally dismantled into scrap metal. But there are a few lucky ones that have been stored as teaching aids in universities and museums, and miraculously are still functioning today.

As a result, this pot camel machine and its supporting pumping equipment were brought to the Pacific coast of Central America in the early 16th century.

“…… Senior Wendesi! Your current site is really not suitable for the development of industry! ”…,

Watching the natives throw bundles of firewood and grass into the hearth, making the pot camel machine make a loud noise, slowly running, and slowly pumping the river water into the cement reservoir on one side, Wang Qiu couldn't help but sigh like this, "...... There are no iron mines, no copper mines, and no coal mines. There's oil on the Gulf side, but it's on the Pacific coast. Although there were excellent harbors, there were no decent ships on the sea, only small rafts and canoes of the Indians, and it was difficult to develop maritime trade...... It's really confusing that people don't know how to climb the tech tree! ”

“…… Therefore, the technology tree of Hope Harbor has been completely deformed by us! ”

Wen Deji scratched his hair with an embarrassed expression, "...... The previous Honshutizgans were, at best, in the technological stage at the end of the Stone Age. Now it has skipped the Bronze Age, the Iron Age, the Steam Age, and the Internal Combustion Engine Era, and has directly ascended to the sky, instantly entering the green and pollution-free solar energy era! Such a leap forward is too terrifying! ”

“…… But the question is, apart from solar energy, what other energy sources are worth developing on your side? ”

Wang Qiu spread his hands very helplessly, "...... Is it hydroelectric power? Let's not talk about how long the dam has to be built by manpower alone, will it delay the main business of logging and making money...... Don't look at me, even if I can get construction machinery, I don't have a driver's license! In addition, gasoline and diesel are also delivered by modern shijie...... Even if the generator set is installed and the poles are erected, do you have a way to train qualified electricians? ”

“…… Well, maybe you can give a biogas digester a try! I can cook with that thing......"

Wen Deji touched his nose and said with some lack of confidence.

At different stages of development, what degree of jishu reserves should human society have?

Based on the list of in-game tech trees in Civilization 5, we can get a rough idea of this.

1. Ancient times:

1. Agriculture - This is the beginning of all civilization, without agriculture there would be no civilization.

2. Pottery, animal husbandry, archery, mining

3. Navigation, calendars, writing, hunting, wheels, masonry, bronze

2. Classical Era:

4. Optics, Philosophy, Horsemanship, Mathematics, Architecture, Ironware

3. Middle Ages:

5. Theology, Civil Service, Money, Engineering, Metal Casting

6. Compass, Education, Knighthood, Mechanics, Physics, Steelmaking

4. Renaissance:

7. Astronomy, music, banking, printing, gunpowder

8. Navigation, Economics, Chemistry, Metallurgy

9. Archaeology, scientific method, military science, fertilizer, rifles

5. Industrial Age:

10. Biology, Steam Engine

11. Electricity, spare parts, railways, explosives

XII. Refrigeration, telegraph, radio, flight, internal combustion engine

Before the arrival of the traverser, the Jishu reserves of the Hongshu Tizgan Kingdom were basically between the second and third levels of the ancient era of the aforementioned tech tree - agriculture, pottery, bows and arrows, and mining jishu were all there, but unfortunately the mines had long been lost in the war. Due to the lack of large livestock in the Americas, the livestock industry only knows how to raise dogs. The astronomical calendar is very complete, and the writing is still in rudimentary form. Brass has been used sparingly, but it is not yet known how to cast bronze.

However, with the arrival of the traverser, the technology tree of this primitive society suddenly became chaotic.

The natives still don't know how to smelt iron, and they can't even make bronze (there are no copper, iron, or tin mines in the vicinity for them to practice), but they are already lighting with electric lights, scouting with binoculars, working with stainless steel knives, drinking water from glasses, eating antibiotic pills to treat diseases, aluminium alloy plates on the dinner table, and colorful beach pants made of chemical fiber fabric...... Obviously, this kind of seedling-fueled jishu flying over is completely rootless, and once the space-time gate disappears and the traverser leaves, they are afraid that they will sadly return to the Stone Age. …,

Moreover, due to the poor starting conditions (Stone Age tech tree), the lack of environmental resources (lack of minerals), the rush of time (less than two years of construction), and the unprofessionalism of the designers. At present, the infrastructure construction of Hope Port is also showing a strange situation no matter how you look at it.

First of all, in the civilian areas on the outskirts of the port, except for the access to some modern industrial products and metal tools, most people can still only live in simple thatched huts, and a few people with relatively wealthy living conditions have replaced the rammed earth walls with stone walls and laid wooden planks on the mud floor, but everything else is still the same - the first brick kiln built by the senior Wen Desi according to popular science books, because the hands and feet of the indigenous kiln workers are too clumsy, they still cannot achieve stable production, and they are far from the dream of letting the people of the whole city live in brick houses, It's still a long way off.

Second, in the aristocratic quarters near the city center, fool-shaped solar-powered street lamps have become common – but not installed on the side of the road, but erected in the courtyard of the home to prevent theft. It also needs to be made movable so that it can be easily moved indoors in stormy weather.

Zuihou, in the "Tin House Palace" where Moon Tokuji lives, is covered with large solar panels, and every day the maid carefully wipes them with a dry cloth. And it's the only place in the city where you can charge tablets and electric cars – Wang Qiu doesn't have a shortage of photovoltaics and power lines, but the problem is that he can't find qualified electricians and users here...... Who told these natives that they didn't have the slightest idea of electricity and machinery?

After securing electricity, the construction of running water was also put on the agenda, and ground was broken - the pyramid standing in the middle of the Port of Hope is actually a large water tower, and the top of the tower is a square cistern. However, because the electricity generated by solar energy is not enough to drive the pumping machine, and it is almost impossible to rely on manual water to carry water, the construction of tap water was in a state of suspension until the pot camel machine was transported.

However, now with the steam engine that lifts water, the problem of power source has been solved.

Next, a series of suspended channels in the city were built with bamboo pipes and wooden troughs to bring clean fresh water to the aristocratic mansions around the pyramids, as well as a series of public pools pre-set in the civilian areas, which according to Wendesi's prediction, would be very effective in improving the health and hygiene of the city's inhabitants and reducing the possibility of disease outbreaks.

However, with the clouds of war looming, the above-mentioned livelihood construction has to be pushed to a secondary position.

At present, the first problem that Wendeji and the time-travelers must solve is how to deal with the incoming Spanish colonizers.

In fact, after obtaining a large amount of money through space-time trade, and through various materials, the details of the Spanish expedition were initially investigated, whether it was Wen Desi or Wang Qiu, who came first, they had already overcome their initial fears, and were very confident that if they only considered dealing with this expedition, with various advanced equipment in later generations, they wanted to defeat the Cortés expedition with only a few hundred people, a dozen old-fashioned arquebuses, and two bronze cannons. It's a simple military operation akin to a road roller running over a puppy.

There is nothing to be afraid of in the old arquebuses of the 16th century, and although it is not easy to buy guns in China, it is very convenient to buy body armor, and there are discounts for bulk purchases. The bronze cannon is not a big deal, it fires slowly, the effective range is less than a kilometer, and the distance is not accurate, unless it is to bombard fixed fortresses and walls, in the field, it is just a sound to scare people. …,

Even if they wanted to uproot the Spaniards' stronghold and fight a tough battle, they could get 100,000 beer bottles from the scrap yards of later generations, pour gasoline, rubber, magnesium powder and other additives according to the recipe invented by the Finns, and make them all into "Molotov cocktails", and then use a stone thrower (from a modern point of view, the jishu of the stone thrower is really very simple, and basically does not violate the ban, and can be ordered to be made in later generations and then transported here to assemble) to throw out this most commonly used incendiary bomb in the Middle East conflict in later generations...... Next, you can happily enjoy the Jungle Meat BBQ Tournament. What did the poor Spaniard rely on to escape the tragic fate of turning into a roast pig? Devotional prayers?

The real problem was that, in order to maximize their own interests, they would also take advantage of the turmoil of the Spanish explorers' invasion to greatly increase the influence of the kingdom of Hun Thitzgan over the whole of Mexico, allowing them to gather resources over a much larger territory, preferably directly in the gold and silver veins that had long been marked on the map, rather than confined to the backwoods of the Pacific coast to buy and sell timber.

Therefore, the kingdom of Honshutizgan, under their control, had to fight not only the handful of Spaniards, but also the Aztec Empire and even its former allies, the Tlaxcalas...... However, Mr. Wen's subordinates only have 7,000 women's troops and 2,000 ancient boys, and no matter how you look at it, the troops are insufficient.

So, Wen Desi still wanted to get some firearms, so that he could be more confident: "...... While the Arquebuses of the Spaniards did not seem terrible, we also did not have AK47s and grenades...... Can you take the space-time gate to places like Burma and Mexico and get some guns? ”

In response to this very excessive request, Wang Qiu rolled his eyes at that time, "...... Next, do you want us to go to Somalia to get you bazookas and Syria to look for gas bombs? Ahem, don't forget, we are state civil servants! Not a smuggler! If you're really so foolish, how should you write your future work resume?! Do you want a job? ”

“…… Having said that, I've always been surprised that the unit that weishenme carried out the crossing mission turned out to be the chengguan, not the army or agents? ”

Wen Deji touched his chin full of stubble, and suddenly threw out such a question - he seemed to have hidden it in his heart for a long time.

However, how should Wang Qiu answer?

…… This one...... Can I tell you that there isn't a single supernatural in the Department of Defense's supernatural department, it's all beer belly uncles and the rich second generation of drag racers?

After thinking about it, Zuihou finally found a reason that was not a reason, and reluctantly prevaricated.

“…… Because it is taboo for the army to do business! Now is not the time when the Navy can resell Japanese cars with tank landing craft! ”

In short, before Professor Yang rushed to Beijing to complete the debriefing and won the strong support of the relevant departments, it is still unrealistic to get a large number of firearms and arms from modern times for the time being—even if there is really an underground way to get guns! Otherwise, it's all over on the resume!

Therefore, the travelers had to find their own way to make guns and cannons in Mexico in the 16th century.
