Although the physics teacher only has a slight understanding of electricity and cannot produce high-quality speakers.

Lou's father only has a slight understanding of music and cannot achieve the change from Zhang Fei's voice to Diao Chan's voice.

But with insufficient technology, materials can make up for it, and limited skills can be improved with software.

With the help of the fourth-level basic production line and the computer they brought, everyone spent three days making a "tone control circuit" that matches the mechanical Three Kingdoms characters.

The young generals use the A-type circuit board + magnetic fidelity speaker, which is the size of a beer cap, and the sound is clear and loud.

The middle-aged generals use the B-type circuit board + drum-type subwoofer, with a deep and hoarse sound, full of vicissitudes.

There is also a customized "front and rear dual speakers" for popular generals, used to create a unique stereo effect.

For example, when Zhao Yun grabs the weapon, he roars, "The Dragon's Courage shines on the silver spear, I will fight in all directions!" The sound is soul-stirring and extraordinary.

Unfortunately, the engineer only works on machinery and construction, knowing how to dismantle the electrical equipment of the war chariot, but not how to develop it.

Otherwise, there would be two more major subjects: acoustics and electrical engineering.

During these three days, Lou Xiaohu and Lou Nannan came many times, but the four old and young men were obsessed with the mechanical Three Kingdoms all day long and had no time to greet them.

At the same time.

The design consulting company produced twenty promotional posters, and through Little Xu, the factory director, contacted the TEP (North America) branch, spending 1.5 million US dollars to commission the "Industrial Light and Magic" special effects company to produce a five-minute high-definition short film.

The mechanical engineering department also worked overtime to design the "Unparalleled Mechanical Zhang Fei."

The final structure is similar to Xu Fei's previous design, not an assembly type, but an upgraded version of the ordinary mechanical Three Kingdoms.

Internally, it uses a chain spring assembly, with multiple gyroscopes set at the stride, waist, and shoulders to ensure stable balance above the waist, even when wielding a weapon, both the left and right sides are equally stable.

In this way, when Zhang Fei shouts "I will kill" for the first time, the long spear strikes once.

When he shouts "I will kill" for the second time, the long spear strikes again.

Shouting "I will kill, kill, kill...hahaha," the entire character sways back and forth under the action of the gyroscope, looking like a madman. When the power is about to run out, the hidden mechanism behind activates and presents a wine jar.

Zhang Fei stops, his right hand leaning on the mechanical long spear, his left hand magnetically attracting the wine jar, and he drinks heartily.

Strictly speaking, this is a one-time mechanism.

If you want to do it again, you must manually return the weapon and wine jar to their original positions.

But without participating, where is the fun?

Xu Fei sent Lou's father and the physics teacher, who were squeezed dry, away, took the Zhang Fei construction drawing, and went to the assembly center of the large swamps light tractor.

"I Have a Record of Ghosts and Gods"

Enter the second-level basic production line, set the maximum power within the safety range, and check the pre-production information.

[Complex mechanical device.]

Principle: lever, spring force, mechanical chain...

Structure: 26cm high, 4.5kg, with 2 main spring drives, 6 secondary spring drives, 12 gyroscopes, 17 machine taps...

Requires metal iron, titanium alloy, phosphor bronze...

Daily output of 10,000 sets, each set can provide 500 energy.

When Xu Fei saw the last part, he couldn't help but rub his eyes.

"500 energy?"

In the previous experimental mechanical watch, a 0.5mm movement could provide 2000 energy.

But the daily output was only 200 sets.

Now the daily output is 10,000 sets, with 500 per set, which is a daily income of 5 million energy!

It can be done in ten days in the laboratory module!

No, there's more.

The new small speaker has a daily output of 20,000 sets, with 50 per set.

The new circuit board has a daily output of 10,000 sets, with 100 per set.

"700 million energy per day, a small gun for a big cannon, I'm going to the top!"

"And, with a daily output of 10,000 sets, each set is worth 1200 RMB, which is equivalent to a daily income of 12 million, after deducting labor, transportation, and electricity, I can still save 10 million."

"Every day there's 10 million RMB!"

Xu Fei stomped his foot, just about to be happy, but a cold wind blew in his face, reminding him of the "Ice Age" to come.

After a few moments of vacillation, he silently completed the production tasks, picked up the petite Zhang Fei, and returned to the office area of the heavy tractor assembly center in a daze.

He then lay on the rocking chair, contemplating how to stockpile oil.

The current price of crude oil is about 13-15 US dollars per barrel, which is 5 US dollars higher than in previous years, which seems a bit inappropriate.

But the Navy SEALs reminded him that there will be a war soon.

Once the war starts, the price of crude oil will definitely double.

Especially when China is about to join the WTO, foreign companies will rush in, and the price of food may skyrocket.

Support us at bit.ly/3iBfjkV.

This is not conducive to his "Ice Age" survival plan.

But as a commoner, he has no control over international affairs.

So, there's no need to hesitate, he should start stockpiling now.

With a daily income of 10 million RMB, equivalent to 1.2 million US dollars, he can buy about 100,000 barrels...which is equivalent to 15,000 tons of crude oil.

The problem is, buying crude oil requires foreign exchange.

Xu Fei looked at Zhang Fei, his eyes lit up, and he contacted an accounting firm, requesting that the toy factory settle with foreign trade merchants in US dollars and apply for multiple overseas bank accounts.

It's easy with South Korea, as the South Korean currency cannot be directly exchanged for RMB, so it must go through the intermediary currency of US dollars, and then it can be directly deposited.

In short, as long as there is money in the overseas account, it can be used to buy crude oil as soon as possible and then shipped back to the country.

The money earned in the country will be used to stockpile cotton and food.

In this way, the division of labor between domestic and foreign is clear.

As for where to store the things bought back?

Xu Fei first thought of the seaport.

After all, it saves transportation costs.

But first, the "Ice Age" will warm up, the polar ice will melt, and the sea will flood low-lying areas, and then it will freeze.

So, he must find a high place.

"The Loess Plateau?"

"But the loess is soft, what if it collapses under the sea?"

"Tibet?""Right, Tibet is close to the Himalayas. If a major flood comes, we can move up the mountain."

"Also, remember the data shows that the Himalayas belong to the south. After the disaster, a new home..."

Thinking of this, Xu Fei counted the population of China and suddenly felt anxious.

Fortunately, after repairing the laboratory, there was basically no shortage of energy.

Recruit more engineers and let Old Xu take a few legions to work on construction.

It's not too much trouble. Just dig billions of caves in the Himalayas, enough to live in.

After the disaster passes, we can move out and rebuild a new home.

But...

The railway to Tibet has not been repaired yet. Even Old Xu has to rent heavy-duty helicopters from Russia to transport the tanks...

"It seems that after buying oil, cotton, and food, we still need to stockpile them in the large swamps."

Xu Fei summoned a semi-transparent panel and looked at the icons on the right side.

A bunch of useless modules were repaired some time ago, including oil drums, cellars, and portable toilets.

Manufacturing oil drums can adjust parameters, with a maximum diameter of five meters.

Building cellars can also adjust parameters, but there is no size limit. As long as there is steel, energy, and engineers, it's not a problem to dig a city, and you can even adjust the shape to form a square, cylinder, cone, or gourd...

"There's no need to dig a city. What if the seawater floods in when the disaster strikes?"

"According to the data, there shouldn't be much happening before 15 years ago. Let's store them here for a few years and then transport them directly to the Himalayas when the railway is repaired."

Xu Fei listed the plan in his notebook, seriously considering it and feeling it was feasible.

At this time, Da Ma walked in from outside, "What are you doing?"

"Contemplating the future." Xu Fei threw the notebook on the desk.

Da Ma curiously picked it up and looked at the plan on it, as if struck by lightning.

Xu Fei asked in confusion, "What's wrong? Did I miss something?"

"No, it's great!" Da Ma nodded heavily and said seriously, "We have to do it this way!"

"Do you have any good suggestions?"

"Oil is a strategic material. With such a large purchase, North America will definitely intercept it. It's better to dig a few large cellars in North America in the name of the Iron Tower Company, stockpile oil together, offset each other, and quietly transport it over when the disaster comes."

"That makes sense!"

"Not only in North America, but also in South America, Europe, Africa, and even the two poles, we need to dig cellars."

"Why?"

"To coordinate materials and facilitate transportation. It's better to use several super oil tankers to transport them back than to bring them back piece by piece and save money."

"That's a good point."

"Also, what if we store so much oil, cotton, and food overseas and they get robbed? We have to arrange for our own people to watch over them. Navy SEALs, heavy infantry, light tanks, heavy tanks, helicopters, warships, fighter jets, and peacekeepers, all ready to go."

"Why do I feel like you're getting more and more outrageous?"

"It's not as outrageous as your plan."

"Huh?"

"No, what I mean is, it's more outrageous not to arrange for people to watch over so many things, isn't it?"

"We don't need such a big lineup. Besides, how much funding is needed to do so much?"

"We're not going to do it all at once. There's still a long time. Didn't you write it in your notebook? It's safe before 15 years ago. We can completely earn money in the first five years and dig while earning money in the middle five years. Stockpile materials while earning money in the last five years and bring the materials back while robbing."

"Are you a bandit?"

"In the last five years, when the disaster comes, if we don't rob, we'll be washed away by the water. Not robbing is as good as not robbing."

"That's true, but that's not called robbing, it's called scavenging!"

After Xu Fei finished speaking, he seriously considered, "Let's set up a temporary storage point in the large swamps first and then... wait until the laboratory is repaired, see if we can activate the secondary base core, and then send a vehicle over there. While building the Iron Tower on a large scale, mortgage loans, and secretly dig cellars to stockpile oil."

Da Ma nodded at the words, feeling that this matter was not urgent, so he changed the topic, "The registration for the Mech Three Kingdoms Battle ended yesterday. All 20 districts in East Mountain were activated. It happened to be winter vacation, and many college students took part-time jobs to buy Mech Three Kingdoms characters. An average of 30,000 players in each district."

"What about Japan?"

"All 10 districts were activated, with an average of 210,000 players in each district."

"So many?"

"According to sales statistics, Japan really doesn't have that many players, and their winter vacation has ended, with at most 100,000 players in each district. But the average number of purchases per buyer is high, with 5-10 sets per person, and some people even collect all 120 characters, then call friends, and even bring their parents to participate."

"..."

"In addition, the operation center, in order to attract popularity, has adopted the tournament mechanism from King of Fighters. Three people form a team and each person has a character. If the character wins consecutively, they can stay on the field and trigger the challenge mechanism. The more wins, the higher the team's ranking. This gameplay has attracted many King of Fighters fans, prompting them to also buy Mech Three Kingdoms characters."

"Ask the distribution and retail partners in Japan for event planning fees. 10 districts, at least 10 million RMB."

"We've already asked, but in the past two days, several financial groups in Japan have contacted the operation center, wanting to take over the general distribution in Japan."

"What's the meaning of the phone call? Let them come to the large swamps to discuss."
