August 20.

Lao Yang, who was far away in Maoxiong Kingdom, sent a message to Xu Ming to report on his progress.

"Xu Ming, I have basically agreed with the officials of the Far East Development Bureau. In the Far East Amur Prefecture, near Heihe, my country, we contracted 170,000 mu of agricultural land. It is now in the drafting stage. It is expected that the contract will be officially signed in September... The efficiency is very fast."

"170,000 acres, the contract fee is quite high, right?" Xu Ming asked.

"It's not expensive. The contract period for 20 years is 170,000 mu, only 1 billion rubles, or 100 million soft sister coins. The average per mu is less than 30 yuan per year. In other words, it is the cheapest barren land in China, and the contract price is about ten times the contract price." Lao Yang said happily and happily.

"And the farm is exempt from taxes for three years, and then it is taxed at 1,000 rubles per acre per year, which remains unchanged forever. At that time, the officials looked at me like a fool and asked me more than ten times if I was sure."

"One thousand rubles does not mean paying 100 yuan per mu of tax? 17 million yuan a year... The agricultural output in the cold zone is not high, and it can only be planted for one season a year. The labor cost and transportation cost are high, so it is not profitable... You will definitely be regarded as a sucker, there is no need to do this."

Xu Ming asked in confusion.

"I know, but the tax rate for foreign-funded farms in Maoxiong Country is about 5% per year, which is not very high. If it is an ordinary wheat crop, even if the yield per mu is 1,000 kilograms of wheat is sold at most 500 rubles. I will give twice the extra money, which is indeed a bit like a sucker."

"But ryegrass can be planted for ten seasons a year, creating an economic benefit of 100,000 yuan per mu. Multiplied by 5%, and no tax of 5,000 yuan a year is allowed to be paid, which is a full fifty times."

"So I have to do not understand the economic potential of ryegrass when those bear officials did not understand the economic potential of ryegrass. When they felt they had taken a big advantage, they set a tax of 1,000 rubles per acre per year on the contract. I would indeed suffer a little in the past two years, but as long as the farm utilization rate exceeds more than 20,000 mu, I will take advantage of it."

Li Guoyang said complacently.

"The Mao Bear is a person who doesn't like to suffer losses. This little cleverness is best not to be discovered by them."

Xu Ming shook his head and said.

"I know, I will grasp the situation well and nothing will happen."

"That's good."

The two ended the conversation.

...

The world of your own.

After more than a week of adjustment and busyness, Xu Ming completed all the preparations.

He made a completely renovated modification of the two turbofan engines of the Martin third type, including the engine central shaft, blades, and combustion chamber, all of which were replaced with lava steel materials with much higher strength and toughness than titanium alloys, lower density, and melting point of more than 3,300 degrees.

After the modification was completed, Xu Ming conducted a performance test on the grassland in the middle of the lake.

It was found that the performance of the turbofan engine with lava steel material has been significantly improved compared with the black crystal blade version of the engine.

Thrust increased by 15% again.

Cruise status stagnation time: 120 minutes

Maximum speed flight time: 75 minutes

Maximum flight speed: 200 km/h

Maximum range: 250 km

In addition, the capacity of the fuel tank remains unchanged by 40 liters, which means that the same volume of aviation kerosene, the factory version of the engine can only last for one hour, the maximum range will not exceed 80 kilometers, and one liter of kerosene can only fly 2 kilometers.

But now the new lava steel engine can double the air stagnation time and increase the maximum range to an astonishing 250 kilometers, equivalent to 1 liter of kerosene, which can allow the flight backpack to fly 6.25 kilometers.

You should know that the fuel consumption of a 1.5-ton household car running on the road is about 8 liters, and each liter of gasoline can make the car run 12.5 kilometers.

Today, the fuel consumption of lava steel turbofan engines is only twice as high as that of a car's gasoline engine, which shows that the efficiency of lava steel engines has reached a very amazing level.

In addition, Xu Ming also spent a day to completely transform the turbojet engine of the Frank-2S flight pedal.

All structures have also been replaced with new materials.

When conducting performance test flights, the comprehensive improvement also surprised Xu Ming.

Because of the outer shell nozzle and central axis of the turbojet engine, Xu Ming used black crystal material, and the surface was cut and polished with space-time and space-grained, with a friction coefficient approaching 0, and at the edge of the nozzle, many concave structures of micro "angle amplifiers" were processed. The characteristic of this structure is that no matter what angle the air molecules are injected, they will be shot straight, increasing the kinetic energy of the flight pedal.

In the end, the thrust of the turbojet engine increased by 35%.

Fuel consumption has dropped by 10%.

Cruise status stagnation time: 65 minutes

Maximum speed flight time: 45 minutes

Maximum flight speed: 240 km/h

Maximum range: 180 km

As for the fuel tank capacity, the 45 liters remain unchanged, and the cost-effectiveness ratio is not very high, but the overall data performance is still very impressive.

"If the environment below is boring and monotonous, such as large lakes, forests of the same plant, barren areas, etc., I can use the Frank-2S flight pedal to cross at the maximum speed at high speed, save time and improve exploration efficiency!"

Although the maximum speed has not been greatly improved, the flight pedal has its own advantages and can play a significant role.

In addition, it is the "exploration suit" suitable for exploration in temperate areas. Xu Ming also made three sets, the colors are yellow, white and blue. There is not much difference in design styles. Two more sets are just for the convenience of replacement.

The production time of several sets of clothes took about half a day to add up, and the craftsmanship was extremely neat.

"It seems that I am becoming more and more like a qualified tailor."

Xu Ming said with emotion.

Then...the preparations have been completed.

These days I said I would have to rest, but every afternoon I would go to accompany Lan Mengxin to buy home appliances and furniture, direct porters to arrange them, add some tableware and kitchenware, clean with Lan Mengxin, etc., and I basically don’t get the opportunity to relax and rest during the day.

At night, when people are in the world of walking, they are fascinated by the engine. They are tired but not tired, and the rest time is guaranteed, but they can't stop. After repeated time and space cutting operations, the mental power is consumed relatively large. Even after successfully thinking about the hollow blades of complex structures, the engine efficiency has been greatly improved. Although they feel mentally exhausted many times, they are happy with each other.

The result is that I fell into a vicious circle called rest and relaxation, but actually busier.

"After all, the "Five Hundred Days Global Exploration Plan" has not been completed, and I am always in a state of nervousness and urgency."

"And this plan must be completed. After all, I still have too little knowledge of the world of my own. It is absolutely impossible to always wander around the grass and hills."

"What's more, the "Five Hundred Days Exploration Plan" has only been completed more than half of the time and space anchor points, and a total of up to 20 space-time anchor points have been set (5 on the Blue Star), and the harvest is huge!"

"There are less than half of the remaining exploration, and I believe there will be a lot of gains, waiting for me."

"Start, you can't stop, continue to set out and move towards the east."

"The latitude of the grassland hill is 21° north latitude and its circumference is about 32,000 kilometers. I want to return to the grassland hill within 60 days and completely complete the global exploration plan!"
