"Okay, then find a chance to do it!" Sun Feng agreed, and the voice assistant told Sun Feng that the monitoring ability of the defense equipment here could not prevent the detection function of the diving armor, and at the same time, the isolation shield extended by the diving armor could evade the detection of this base. In this way, Sun Feng can do it.

The people who work here, if they mine energy stone, they all have a special person in charge to transport it, and Sun Feng has an instrument inspection at the exit they pass through after work, so the workers can't take the energy stone with them at all.

However, Sun Feng has a storage space, and Sun Feng doesn't have to worry about this when the time comes. According to the popular science of voice assistants, like the current light star system, there should not be a third yuan of storage space. So Sun Feng's storage space will not be discovered at all.

However, this time, if Sun Feng uses the mining and excavation equipment in the deep-sea development smart factory to mine, and uses the original electric energy as an energy source for mining, the speed will definitely be slower than that of the Bright Federation.

Therefore, Sun Feng plans to use medium-grade energy for his mining equipment and machines, so that the speed of mining will be increased, according to the voice assistant's words, like mining this ore vein, it will be done in one night, and all the associated energy stones in it can be mined!

There will definitely be a loss, using the intermediate energy stone as an energy source to mine the energy stone, it does seem to be too luxurious, but the energy stone will definitely be earned when the time comes, there are more than 300 intermediate energy stones, and more than 1,500 primary energy oil. However, if you want to mine this vein, it is estimated that it will cost thirty intermediate energy stones, which makes Sun Feng's heart hurt a little! However, when the time comes, you will get three hundred intermediate energy stones and more than one thousand fifteen hundred primary energy stones, which is worth thinking about. Besides, the thirty intermediate energy stones spent are not consumed all at once, and they can also allow the ship-driving equipment to continue to be used for a period of time. When the time comes, you can mine other veins! After calculation, this wave will not lose money, and it will make a lot of money.

The first day of boring work passed like this, Sun Feng's physique was sure enough, and he didn't feel tired at the end of the day, after eating, the three Bai stars ran to the entertainment city of the base to play. Sun Feng stayed in the dormitory, and he planned to act later! Once he succeeds, he is ready to leave, either quit his job and return to Silver Star, or go to other mines here alone to continue stealing energy stones! Anyway, if he doesn't make one this time, he doesn't plan to leave.

Soon, it was time to rest, and Sun Feng quietly left the dormitory alone. After coming to an uninhabited alley, Sun Feng quickly took out the diving armor from the storage space and covered himself, and at the same time opened the isolation shield, so that Sun Feng's diving armor became invisible all of a sudden.

Sun Feng drove the diving armor to the front of the No. 125 mine! The mine, which looks like a deep pit from the air, is surrounded by all kinds of machinery. Usually workers go down to the bottom of the mine by machine. This mine is very large, estimated to be 10,000 meters in diameter! From the sky, it looks like the mouth of a monster, bottomless. This time, Sun Feng did not have to take the traffic like a worker to go down to the bottom of the mine 10,000 meters below. He had a diving armor and flew down on his own.

There are all kinds of steel giant arms in the mine, all kinds of mechanical arms that Sun Feng can't understand, machinery and equipment are running, and there are workers who work day and night in three shifts. At a distance of 10,000 meters, Sun Feng soon came to the bottom.

"Slowly stretch out the isolation shield, we have to drill holes to penetrate the 2,000-meter-thick rock formation, and enter the Zhong ore formation, and then the real start will begin." Voice assistant said.

"Good!" Sun Feng looked around, and the rock formation under his feet was also a rock formation, but this rock formation had not yet been mined and drilled, so there were no machines or workers.

After propping up the barrier, the voice assistant released a digging drill about the size of a car from the storage space, which was already equipped with an intermediate energy stone.

With a "click", I saw a cone-shaped object sticking out of front of it, and it began to drill into the rock formation.

"Boom, boom!" With the dust and dust in the sky, and the debris flying, a tunnel leading to the bottom of the rock formation appeared in a few seconds. The speed of such drilling is fast, but the movement is also large, and the boom is deafening, but there is an isolation shield, and these movements cannot be conveyed.

In just one minute, the 2,000-meter-thick rock formation was drilled through by this excavation machine, and the diameter of the hole was 5 meters in diameter, enough for the diving armor to go down.

"Damn, it's so powerful with mid-level energy! A 2,000-meter-thick rock formation was drilled in one minute. Sun Feng said with some surprise.

"Alright, let's go down."

Soon, Sun Feng drove the diving armor through the tunnel and arrived at the Zhong Ore Layer. Looking at this yellow-black, yellow-black ore body, Sun Feng said that there is no such ore on the earth.

"This kind of iron ore, similar to the iron ore of your earth, is the best material for building mechanical warships. Well, we're not good for these things, we just need the energy stones that come with this ore! The voice assistant said.

"To mine such energy stones, we don't have to go to great lengths to mine all the veins. Primary energy stones are generally the size of a grinding disc, and intermediate energy stones are only the size of a palm. These energy stones are associated with these mines. We're going to use a type A gopher to drill down and dig it out. ”

Next, the voice assistant released 300 Type A gopher drilling devices. These devices appear to be the size of a motorcycle. There are eight robotic arms, all of which have a conical burrowing object. 300 Type A gopher mining and excavation equipment plunged headlong into these hard ore bodies in an instant. These hard rock masses were drilled out of 300 holes by 300 drill gophers at once.

Guided by the detection and search function of the diving armor, these devices all know that the more than 1,000 energy stones are in that direction, so they all drill towards the places where those energy stones are.

In this way, five or six hours later, these drill gophers with the ability to defy the sky sent more than 1,500 primary energy stones and more than 300 intermediate energy stones to Sun Feng's eyes.

Sun Feng smiled, put all these energy stones into his storage space, patted his ass and left.

"With the use of medium-grade energy, the capabilities of these machines have increased in all aspects. If you use electricity for these machines and equipment, it is estimated that it will take a month to get these energy stones. Now it's only a few hours, so fast! Sun Feng sighed with emotion, you must know that this Zhong vein has a rock mass of 100,000 cubic meters. These more than 1,000 energy stones are distributed among the 100,000 cubic meters. Also, the hardness of these rock formations is many times harder than that of iron ore veins. Even the hardness of diamond is not that hard! Otherwise, these metals would not be able to make materials for mecha warships.

After finishing it, Sun Feng looked at the time, there were about five or six hours before he started work, and as soon as he got to work, Sun Feng submitted his resignation letter to the top. At that time, the most you will pay for the contract fee is the most. In the few days he came here, Sun Feng had received a lot of money from the Bai Star people on the street. It was also deposited into a bright federal bank card that he had just opened. Now it's ready to use.

After going back and sleeping, Sun Feng went to resign, and after resigning, Sun Feng did not leave this barren planet immediately. On this planet, there is a single city - the trading city. This city is a trading city for all kinds of ores and minerals that have just been developed on this planet. Coming to this city is usually the senior management here to have fun and spend a vacation. Then there are some merchants who come here to buy all kinds of ores.

So the city basically has places to shop, eat and stay, and have entertainment. Sun Feng planned to use this place as a foothold, and then when he saw where there was an energy stone, he would run over to dig it!

He is the only one like Sun Feng to do this. Because he has mining equipment, if it is someone else, it is like having the same idea as Sun Feng, but without mining equipment, it is useless, even if he finds it, he can't mine it. Besides, there is also the military monitoring here, and if you bring in a lot of mining equipment to mine, it will definitely be discovered.

Sun Feng is now very glad that his deep-sea development smart factory has a storage space, and all his mining equipment is in it, which can be used at any time. There is also an isolation shield to protect yourself from committing crimes, hehehehe!

"Let's go, let's find the energy stone ourselves!" This planet is about the same size as the earth, and it is not very big to say, Sun Feng's current detection and search function can detect a radius of 10,000 kilometers, so he might as well find it himself. He felt that the developers of the Bright Federation had not necessarily discovered all the energy stones of the entire planet. He can still pick up the leaks.

A week passed, Sun Feng found a total of two regions with energy stones, and then he mined them by himself, and obtained 500 intermediate energy stones and 3,000 primary energy stones at once.

Now, Sun Feng had a total of a thousand mid-grade energy stones, including some of the energy stones he got from the Ancient Altar and the ones he got from the Milky Way. There are also four thousand primary energy stones. This time, Sun Feng can be regarded as having a small amount of capital.

Sun Feng planned to go back to the Trade City to rest and continue to do it. When Sun Feng returned to Trade City, the next day, he heard the shocking news that an interstellar pirate fleet was looting all over the nearby star field. Many of the mines and planets of the Bright Federation have been robbed. Quite a few people died. The only army now stationed on Planet 599 had left for the front line yesterday to join up with the other mine-type armies in preparation for a battle with the interstellar pirate fleet.
