Liu Feng came to World No. 2 mainly to find a power system that suits him, and as for the one on Earth, that is the next step.

"The Holy City of the Orcs!" Liu Feng set his sights on the Holy City of the Orcs.

Why?

Why didn't Liu Feng choose the Bright Empire or the Magic Holy City, and go to the Orc Holy City.

A very simple example.

The Orc Empire has been able to fight with humans for so many years, and there is nothing good in their hands?

These orcs get the things of the human magician, will they return them to the enemy?

No matter how stupid the orcs are, they will not do this, if they go to the Magic Holy City, there must be something over there, but the value of what Liu Feng wants in the Orc Empire is compared to the value in the Magic Holy City.

Which place will be more important, and which place will be more difficult to get?

Of course, it's the Magic Holy City, and the inheritance of the space system or the thunder and lightning system is estimated to be a treasure in the Magic Holy City.

In the Orc Empire, as long as there is, then it will definitely not be said to be more precious than in the Magic Holy City.

The Magic Holy City is in the empire of the business alliance, and the business alliance is said to be the place of faith of dozens of gods.

And the Orc Empire, the surrounding area is extremely empty, and it is easy to run.

I'm here to dig the corners of the orc empire, so it doesn't matter if you offend.

How are you going to get to the Orc Empire?

Merchant!

Lone merchants, Liu Feng knew from Baicao that there were lone merchants who sold some contraband items of the Human Empire, such as dwarves' high-quality weapons, armor and the like.

The dwarven weapons are actually forged ones, low-energy alloys mixed with magical materials.

That is, it is equivalent to mixing and forging the bone powder of alien beasts, that is, the bone powder of Warcraft, with metal.

It's too simple on Earth, a 60,000-ton water-pressed forging machine can make a dwarf go bankrupt directly.

Of course, Li Feng's purpose is not to make money, but to penetrate into the enemy.

"I'm going to have a signal relay satellite or something." Liu Feng muttered in his heart.

Directly inside the temple, the space crystal ball was opened, the third world!

"Sir?" Andy asked tentatively when he heard the alarm sound from his rushing watch.

"How was the potion given to you last time?" Liu Feng asked.

Andy's face was ugly, the last time Erin disappeared, it took a lot of effort on his side to suppress it, but when Liu Feng mentioned the potion, Andy didn't dare to say anything.

The potion does work, and the ingredients of the potion have been analyzed in the family, but it is something that has never been seen before, and there are many kinds of branch structures that have not been seen before.

"Sir, the potion works well." What else can Andy say.

In this world, an individual's physique actually determines the position, just like the physique of the person in the space fleet is the strongest, although the physique has little effect in peacetime, but in the event of a war, a captain with a strong physique, even if he reacts half a second faster than the other party, can also determine victory.

"I need Relay Satellite 3001, ten vials of potions." Liu Feng said directly.

Andy felt very uncomfortable when he heard this, and Andy also knew what Liu Feng was doing when he caught Erin, just to know all kinds of detailed information.

"How many?" Andy had a lot to say, but in the end he just said it.

"Try another one, you don't need anything else, it's blank." Liu Feng opened his mouth and said.

No. 3001 relay satellite, the first 3 is the model representing the satellite, and the No. 3 planetary internal communication satellite.

001 represents the priority delivery level, reaching any planet, the first thing to reach the interior of the planet is this kind of small satellite, and then a large number of drones, guard towers and the like.

This coverage area is 10,000 kilometers, which is enough for use.

The transaction went smoothly, the entire satellite was the size of a football ball, equipped with a pulse engine, and could fly to a predetermined altitude on its own.

After Liu Feng set it up, he let go of the satellite, and the satellite ejected and took off as soon as it called, this satellite has a primary defense system, an advanced camouflage system, that is, it detects a movable object within a certain range, and it will automatically avoid it in advance.

A nuclear battery is used.

Nuclear batteries, also known as "radioisotope batteries", are made by converting the thermal energy of isotopes into electrical energy by converting the heat energy of isotopes into electrical energy during the decay process by continuously emitting rays with thermal energy during the decay process. Nuclear batteries have been successfully used as a power source for spacecraft, a power supply for pacemakers, and some special military uses. On August 7, 2012, the American Curiosity rover arrived on Mars, with a nuclear battery life of up to 14 years. A nuclear battery is a device that uses radioisotope decay to release energy-carrying particles (such as α particles, β particles, and γ rays) and convert their energy into electrical energy. According to the level of voltage provided, nuclear batteries can be divided into high-voltage type (hundreds to thousands of V) and low-voltage type (tens of mV-1V or so) According to the energy conversion mechanism, it can be divided into direct conversion type and indirect conversion type. More specifically, it includes direct charge nuclear batteries, gas ionization nuclear batteries, radiated volt effect energy conversion nuclear batteries, phosphor photoelectric nuclear batteries, thermally induced photoelectric nuclear batteries, thermoelectric nuclear batteries, thermionic emission ~ emission nuclear batteries, electromagnetic radiation energy conversion nuclear batteries and heat engine conversion nuclear batteries. Among them, direct rechargeable nuclear batteries and gas ionization nuclear batteries belong to the direct conversion type and are less widely used. At present, the most widely used are thermoelectric nuclear batteries and heat-engine conversion nuclear batteries. Due to its small size, light weight and long life, and its energy size and speed are not affected by the temperature, chemical reaction, pressure, electromagnetic field, etc. of the external environment, it can work in a large temperature range and harsh environment.

Liu Feng found that the other party's battery had been miniaturized, and the current provided could propel the ion thruster.

That is, the ion engine, this kind of engine is very powerful, Liu Feng feels that he is going to drool.

The first condition for the operation of the ion engine is the production of ionic gas. This usually needs to be done by an electron gun. The electron beam emitted by the tubular cathode is ejected ~ into the magnetized ionization chamber and collides with the gas atoms charged in the chamber, causing the atoms to ionize into monovalent positive ions. As shown in the diagram above, a pair of metal nets are installed at the other end of the ionization chamber, and a voltage of thousands of volts (1280 volts in Deep Space 1) is added to the net, which accelerates ions to a speed of 30 meters per second and discharges them from the tail, forming an ion beam that generates thrust. In this respect, ion propulsion is the same as traditional chemical propulsion: the thrust is generated by the ejection of the substance, but in a different way.

This ion engine is very explosive.

A scan of the watch yields detailed data, but there are some things that do not exist on Earth, which is a material limitation.

"Collect material samples!" Liu Feng has one more task this time.

Baicao has a tablet computer, and the nuclear battery is not exactly the kind of lithium battery or the like, it is not charged when it is not working, and the charged lithium battery cannot be transmitted in space.

Of course, if Liu Feng goes over to get it in person, there will be no problem, and Liu Feng will not have much of a problem wrapping items with space energy, but if he lets it go, there may be a huge problem.

Therefore, when Liu Feng takes things, he generally does not wrap them with space energy.

It's nearly 5,000 kilometers away from the Orc Holy City, so this satellite is on the White Grass side.

With this, you can connect the guard sentry placed on the ground, Liu Feng still has four in his hand, one is used in the place of trading, and two are used in the hometown here, and then Liu Feng is ready to leave one outside the holy city, prepare the back road, if the matter reaches the point of last resort, then sacrifice this sentry.

Li Feng landed on the side of the Orc Empire in the Northern Fortress, dressed as a warrior, with a big sword behind his back, and the big sword was more than two meters high.

"Master, master, this way, this way." Liu Feng took advantage of the night to land in the north near the side of the Orc Empire, and after walking for less than half a day, he saw a huge Earth Dragon, which was completely two varieties of Earth Dragon.

The Earth Dragon is a large lizard and is a vegetarian, and the Earth Dragon is a wurm creature.

"Where?" Liu Feng asked.

In order to rob the merchant resources, the various tribes of the Orc Empire will intercept the merchants who enter the Orc Empire here.

"In the territory of the fox people, there are more than thirty fox girls ~ slaves over there, all of them are virgins ~ women." The orc seemed to be a minotaur, and said with his mouth wide open.

Orc slaves are actually destroyed by other tribes, and they will be reduced to slaves, and these orc girls with high slave value will be sold to human traders.

"I'm going to the Holy City." Liu Feng shook his head and said.

"But the master has good things?" The minotaur asked, wide-eyed.

"Get out!" Liu Feng scolded directly, say whatever you have on the orc's side, don't come to any twists and turns, because they don't understand, orcs like straightforward people, if the orcs think you are a sinister, despicable and cunning villain, it will not be good to do business in the future.

Not only was the minotaur not annoyed by Liu Feng's shouting, but he lowered his body and said angrily: "Master, there are two fox girls on the Earth Walking Dragon, although they are not virgins~ women, but they are also high-grade goods, may I ask what the master wants to change?" ”

"My master is a magician, I am the first follower, this time to exchange for some rare magic props, you fox people have?" Liu Feng said directly.

"Master, I don't know about this, but if you want to say the richest, which is our fox ......." The minotaur's eyes lit up and he looked at Liu Feng, no wonder the equipment was so good, it turned out to be a follower of the mage master.

Before the minotaur finished speaking, he was kicked by Liu Feng and flew out at a distance of more than ten meters.

"Get out!" Liu Feng shouted angrily.

When dealing with orcs, one is to be straightforward, and the second is to have strength, if they don't have strength, these orcs will become robbers.

The Minotaur is at least two meters two or three meters tall, and it looks like a mountain of meat.

was kicked out by Liu Feng's physical strength, and the minotaur looked at Liu Feng, and his saliva was about to flow down, such a strong follower.

"The big housekeeper, the big housekeeper, there are good goods." The minotaur got up and came to the side of the earthwalker, which was about fifteen meters long, and there was a rectangular hood on its back in the middle piece.

"Niu Yuan, what's the good thing?" An elderly fox man walked out and asked while looking at Liu Feng.

"The followers of the Master Mage, who want to exchange for magic items." Niu Yuan replied.

The old fox man looked at Liu Feng, and a green light flashed in his eyes.

"Human Warriors!" As soon as the old man of the fox man slapped Niu Yuan, Niu Yuan picked up the old man, and the old man shouted at Liu Feng.

Liu Feng took out the big sword, and then tore open a magic scroll, which was used for protection.

"Don't come here, cunning foxman!" Liu Feng opened his mouth and shouted.

When the old fox man saw this scene, not only was he not angry, but he was very happy, the cunning fox man, this is the pride of the fox man, of course, if it is a cunning human, it is a derogatory term.

From the mouth of a powerful warrior, the cunning fox man is said, well, this is an affirmation of the IQ of our fox people, and it is a recognition ...... our fox people.

"Human warriors, I swear by the heroic spirits of my ancestors that I will not cause any harm to you, powerful magic props, we fox people have a lot of them, I don't know what good things the warriors bring?" The fox man asked.

"Hmph, cunning fox man, you didn't say your name when you swore just now, the mage master directly asked me to go to the holy city for auction, this time I brought a hundred sets of dwarf boutique armor and weapons, all of which are suitable for the shape of the bull's head." Liu Feng snorted.

“……。” The old fox man glared.

"I'm a fox man, Sinai. Guate. Mountain. Stove. Hammer. The saint swears by the ancestral soul that he will not use tactics against the human warriors in front of him. Sinai spoke.

Liu Feng heard it, good guy, this fox man has dwarf blood, that is, there are dwarves on the ancestors, so he has the title of furnace, and there are forgers on the ancestors, so there are hammers, and there are top powerhouses.

Ahem!

Maybe it's the offspring of an orc born to a dwarf king.......

"May I ask the name of the human warrior?" Sinai asked.

"I can't say my name, you cunning fellows, some of you are well versed in curses, you can just call me gold." Liu Feng opened his mouth and said.

"Okay, Gold, can I take a look at your stuff first?" Sinai asked.

Liu Feng took out a chop~horse~ knife, this kind of chop~horse~ knife is nearly four meters long, with a sharp angle in front.

The fox man's eyes widened, this chop~horse~ knife looks at the thickness, and the weight is incredible.

The minotaur was even more drooling.

"Gold Warrior, can I let this servant of mine try it?" Sinai asked.

Liu Feng nodded, and Niu Yuan picked up this chopping ~ horse ~ knife, and the layers of patterns on it showed the dwarf's exquisite forging technology.

"This is forged by the Great Grandmaster of the Dwarf, and a hundred of them are such weapons." Liu Feng smiled in his heart, orcs are more ignorant, and the first thing to look at is the weight.

"Lord Steward, this is heavier than a tiger's hammer." Niu Yuan had a hard time raising one hand.

As soon as Sinai stretched out his hand, a red light fell on Niu Yuan's body.

Niu Yuan roared angrily, roar!

There is actually a layer of red light on this chop~horse~ knife.

"Superb!" Sinai exclaimed, only the best weapons of dwarves can activate such energy attributes.

"Who's up ahead?" Someone suddenly shouted in the distance.

"Gold Coin Warrior, please follow me, there are twenty-one legendary-level magic items in our clan." Sinai said eagerly.

Liu Feng looked at Sinai and nodded, Sinai actually waved his hand and put away Niu Yuan's chop~horse~ knife.

"If the transaction goes well, I can give your quadruplets fox girls, and they are guaranteed to be virgins~women." Sinai even spoke.

"This ......." Liu Feng hesitated.

"You can also bring it back to your mage." Sinai saw that Liu Feng was a little hesitant and immediately said.

Liu Feng nodded: "Okay!" ”

"Later, this distinguished guest has already agreed to go to our fox clan." Sinai said to the orcs a hundred meters behind him, orcs of different races and tribes will keep a safe distance.

"Gold Coin Warrior, it will take a while to reach our clan here, these two maids are my personal gift to Mr. You, although they are not virgins~ women, but their value is also very high." Sinai waved his hand, and the six fox girls who lived here immediately came to two, and two of them looked about the same.
