April's and the envoys' power to attend classes was exchanged for the right to mine minerals.

In the end, Aprilier and Fran were at loggerheads and managed to keep the rent and taxes at 18 percent, which was already very good for Hobruns.

After all, lying down to earn almost one-fifth of the net profit is pure pie in the sky.

In addition to this, there is also a condition that classes are open to the embassy.

This is actually not a big deal, and the course of the "Journey to the Underworld" is even open to all the villagers of Lingqi Village, as well as to the people of the more envoys.

However, Fran still said in advance that it was okay to go to class, and it was absolutely not allowed to make noise in class.

Especially if you hear something in the course that is different from their philosophy, they will not accept any rebuttals.

This can be regarded as Fran giving them a preventive shot, not to mention anything else, while believing in the god of fire, while believing in the "Lord", this is if it is put somewhere else, it would be good to meet without brains.

……

Two fully automated ore refineries are still under construction, and the "Motorized Infantry Equipment Manufacturing Plant" in the base has been completed ahead of schedule.

Tang Hao couldn't wait to connect to the internal system of the "Motorized Infantry Equipment Manufacturing Factory", and then smoothly extended a grid forward on the building tree diagram.

The architectural drawings of the "biological laboratory" were lit up.

However, when Tang Hao chose the "biological laboratory", his originally excited face quickly collapsed.

"Adjutant, explain to me, what is high-energy liquid gas?"

Among the materials needed to build the "biological laboratory", it is clearly written that "high-energy liquid gas" is needed, and it is a full 50 tons.

"High-energy gas is a hydrocarbon, and liquid high-energy gas has a higher energy density and is often used as a subordinate substitute for metallic hydrogen. ”

"In addition to being used as a fuel, the chemical properties of 'high-energy liquid gas' are also commonly used in various scientific laboratories and are one of the important materials for scientific research."

Tang Hao Khan said: "I don't care what this 'high-energy liquid gas' is, what is the use, I will ask you, where are we going to get fifty tons now?" ”

Hydrocarbons such as "high-energy liquid gas" are not uncommon in the universe, and hydrogen is the most abundant element in the universe, and the fusion with carbon is also common.

However, these compounds are generally free, occasionally concentrated on some extremely cold planets.

The star "Uriel" does not meet the corresponding conditions, and is obviously not included in this list, and another situation in which "high-energy liquid gas" is formed after the paleontological community is decomposed and fermented by bacteria.

"In other words, 'high-energy liquid gas' is an associated mineral similar to oil like natural gas?" Tang Hao relied on the memory of his previous life and reluctantly understood the adjutant's explanation.

The adjutant replied: "Yes, from what we know now, there should be traces of paleontological activity on the 'Uriel' star, and if this kind of resource can be found, the storage location of the 'high-energy liquid gas' will definitely be found as well." ”

"Automated ore refineries can also collect such deposits, Your Excellency, the only difficulty is how to find them."

Tang Hao rolled his eyes: "Of course I know what the difficulty is, the other mineral deposits are okay, there are enough proven mines in Hoblens." ”

"But coal and oil, do you see anyone in Hobruns using them? If there are no ready-made resources, do we have to rely on the 'high-dimensional projection scanning' of the 'orbit command center' to find it slowly one kilometer at a time? ”

The adjutant thought for a moment and said, "Maybe we can use a more primitive method, it is said that in ancient times, when oil exploration technology was not yet available, the only way to find oil and gas deposits was to look for asphalt lakes." ”

After some explanation by the adjutant, Tang Hao basically understood that the asphalt lake was the so-called "oil seedling", that is, the formation of oil and gas mines after they emerged from the ground through cracks in natural rock formations.

"Well, I'll tell Fran to find April, hopefully I'll find it in Hoblens."

……

The plan to build a "biological laboratory" was put on hold for the time being, but after the "motorized infantry equipment manufacturing plant" was built, it should still be put to use.

The "Motorized Infantry Equipment Manufacturing Factory" produces a total of seven different types of individual combat armor, ranging from light to heavy to special warfare.

The most basic type of individual combat armor is the "marine" armor.

The structure of this type of armor is very simple, the internal force feedback power skeleton, the energy source is the type I cold fusion power core, and the outer armor thickness is stronger than that of the "Octopus Mark III power armor", which belongs to the light individual power armor.

The "Marine" armor is equipped with an electromagnetic spike spur from the factory, and the power is not bad, although the range and muzzle kinetic energy are slightly inferior to the "Area Guard" electromagnetic sniper rifle, but it is completely superior in terms of rate of fire suppression.

The operation of the "marine" armor is quite foolish, and even an untrained ordinary person can learn to operate the armor in ten minutes and quickly enter the battle.

This is a very cost-effective armor, which also means that the soldiers who wear this armor to the battlefield are basically the most basic cannon fodder troops.

Perhaps they could barely hold up the battle line in trenches and pillboxes, but in the face of heavy weapons, there was little difference between being armored and naked.

Even in the face of multi-legged electromagnetic kinetic energy gun vehicles, the armor of the "marines" is somewhat difficult to protect itself, and only in the face of the Gatling gun chariot, it can barely fight it.

Even with these shortcomings, the "marine" armor still became a standing combat force of the militia and government army in each colony with its extremely low cost and high versatility.

And in addition to this set of armor, the other six types of armor, like the "Heavy Hammerman" heavy blasting armor; "Angel of the Battlefield" nano-repair armor; "Purgatory bats", high-energy radiation armor, etc., all require "high-energy liquid gas" for manufacturing materials.

In this way, the only armor that the "motorized infantry equipment manufacturing plant" can make at this stage is the "marine" armor.

"Britz, are you free? Selena has something new over there, and she said she wants to find someone to test it, why don't you try it? ”

Britz, who had just come off the space engineering vehicle, was stopped by Mamie, during this time, there were more people sent to the "Journey to the Underworld", and there were only three or five core members left, so Mamie found him.

Britz took off his gloves, unscrewed the kettle he was carrying, took a sip and said, "Okay, didn't we just finish building a new factory?" What's new this time? ”
