"I've already dived to a depth of more than 5,000 meters." Sun Feng looked at the pitch-black sea water, looked down at his feet, and still couldn't see the bottom, and the light screen of the diving armor showed that it was still more than a thousand meters away from the bottom of the sea before reaching the ground.

"Alarm alert danger creature approaching, dangerous creature approaching!"

With the voice assistant reminding, Sun Feng saw through the display screen of the diving armor that a five- or six-meter-tall monster behind him pounced towards him with teeth and claws.

"Damn, this is an octopus?!" Sun Feng was stunned for a few seconds before he saw that that guy was actually an octopus! The octopus that was seven or eight meters large, and the tentacles were estimated to be eight or nine meters long, and at this time, the big dark brown guy was using its big tentacles to begin to wrap around the diving armor.

"Nima, the average octopus is one or two meters tall and reaches the sky, I didn't expect to encounter such a monster in the deep sea." Sun Feng was frightened for a while, and was about to drive the diving armor to escape, but the diving armor was entangled by four or five huge tentacles.

"Ah~" Sun Feng shook for a while, obviously the diving armor had been entangled by the big octopus.

"Dangerous creatures entangled in the diving armor, did you activate the weapon system to fight back?" Just when Sun Feng was shaken and dizzy, the voice assistant prompted.

"Your sister, it's long overdue." Sun Feng yelled.

"Start activating the Deathlight Shot Weapon System!" The voice assistant said coldly.

I saw that the diving armor had been completely entangled by the big octopus at this time, and it was spraying ink on the diving armor.

"Whoosh!" Red dead light shot out from the diving armor's body, and those dead lights hit the tentacles of the big octopus, and the tentacles were instantly amputated like tofu being cut.

The next moment, the entire big octopus was shot to pieces by the death light!

"Damn, that's awesome." Sun Feng saw through the light screen that the big octopus was completely shot into pieces by the diving armor, and he was dumbfounded.

He used to know that the diving armor had a weapon system, but he had never used it, and now that he used it, he didn't expect it to be so powerful, killing the big octopus in an instant, which was N times more powerful than Iron Man.

"Wiped out." Voice assistant said.

"Well, that's great, with this weapon system, mom doesn't have to worry about me hanging on the bottom of the sea anymore." Sun Feng patted his chest and said.

"Alright, move on." Sun Feng said to the voice assistant.

"Okay."

"By the way, the detection coverage of the deep-sea development intelligent system is currently only 50 kilometers around, is there any way to expand the range? At present, the coverage range is only 50 kilometers, I don't feel that it is enough, the sea is too big, and it is difficult to find the veins according to this exploration. Sun Feng chatted with the voice assistant as he moved forward. Although it can detect and cover a radius of 50 kilometers at present, it is already an existence against the sky in the eyes of current technology, but in Sun Feng's eyes, it is really not enough.

"There is a way, in fact, the maximum limit of the detection function of the deep-sea development smart factory can reach a radius of 1,000 kilometers, because the earth does not have that kind of high energy, and can only use the most garbage electricity, so I can't help the host." The voice assistant explained.

"Damn, this deep-sea development smart factory is really picky, and it even said that electricity is the most garbage energy it has ever used, and it said that it can barely be used." Sun Feng was a little crazy.

"We used to use X energy sources, who told you that the earth doesn't have it, so there's no way."

"However, the nuclear energy of your earth is better than electricity, and if you use nuclear energy, the detection and search coverage can reach a radius of 300 kilometers." Voice assistant said.

"Nuclear energy? Where did you ask my brother to get it for you?! "You must know that some small countries secretly engage in nuclear bombs and secretly buy those raw materials for making nuclear energy, all of which are made dead by banana guys, if Sun Feng dares to do this, he will be checked in minutes.

"Forget it, let's find a way in the future, we can't do this yet." Sun Feng thought about it, and then stopped thinking about this headache.

After wandering for a long time, when Sun Feng was about to go home, the voice assistant prompted that a vein had been found fifty kilometers ahead!

"It's an iron ore vein!" The voice assistant prompted.

"Iron ore veins?! God help me. "Sun Feng is overjoyed, you must know that he built a Marl iron ore mine a few days ago, and now he has put the 30 million iron ore he stole in the South China Sea last time in the underground warehouse of the Marl iron ore mine. In other words, if Sun Feng sells out the 30 million tons of iron ore, then he will have no iron ore to sell in the future. I didn't expect him to encounter another iron ore vein today, so lucky.

"Let's go, go over immediately." Sun Feng said excitedly.

It didn't take long for Sun Feng to come to the iron ore vein on the bottom of the sea, which was already more than 7,000 meters deep below the sea surface.

"Probe, how much storage."

"Yes, start probing, probe, probe, probe, probe! According to the host, the current iron ore storage capacity is about 1000000 tons, large iron ore veins. Buried 10 meters underground, it is considered a very easy iron ore to mine. The voice assistant prompted.

"OMG, 100000 tons! My Buddha, Hair la Hair. Sun Feng was ecstatic, tears of laughter almost flowed out, and after tiring his hairstyle, Sun Feng muttered: "The first time I encountered such a shallow iron ore vein buried, it was only about ten meters, if it weren't for the sand on the seabed, this kind of mine should be an open-pit iron mine on land." ”

"Lao Tzu picks up and sees what type of iron ore it is!" Sun Feng opened it directly, and the diving armor directly shot out several dead lights, and a small pit was blasted out at once, Sun Feng immediately squatted down and picked up a few minutes, and then took out a piece of iron ore the size of a basin.

Sun Feng looked at this piece of iron ore, and showed a happy expression on his face: "Haha, I didn't expect it to be magnetite ore, well, it is the best iron ore among iron ores." ”

The iron ore that Sun Feng stole in the South China Sea last time was a hematite, and hematite is also a relatively good iron ore, with an iron content of about 70%. Therefore, last time, Sun Feng's iron ore was generally sold at a higher price, and some iron ore with lower iron content would be sold at a much lower price.

For example, siderite (mainly FeCO3) has a theoretical maximum grade of 48.3%, which means that the iron content is about 48%. There is also limonite, which has an iron content of about 62%. The iron content of these two iron ores is lower than the price at which hematite is sold.

The iron ore discovered by Sun Feng this time is magnetite, and the iron content of this iron ore is about 72.4%, which is the highest iron content.

Magnetite is a mineral with ferromagnetic properties, which is rich in ferric oxide, produced in metamorphic deposits and endogenous deposits, and becomes hematite or limonite after oxidation, which is the main raw material for ironmaking.

"Yes, yes, not only magnetite, but also 1000000 tons of storage, now the Marl Iron Mine will have to sell iron ore in the next few years." Sun Feng was very happy that the discovery of this vein this time basically solved the problem of the supply of goods in his Mar iron ore mine. Anyway, when it sells out, he just comes here to dig up and replenish the past.
