"Ten Thousand Years of Cold Iron?"

Luo Chong felt that this title was a little familiar, as if he had seen it in some fantasy novel, so he asked: "Is this kind of cold iron harder than the super alloy refined by modern technology?"

"It's hard to say. Bubbles replied: "I don't know much about the highest level of science and technology on the earth, and we can't touch those levels yet." ”

"Well, that's right. ”

Luo Chong nodded, and the first thing that came to mind was: "If you use this 10,000-year-old cold iron to build a shield, is it much stronger than ordinary just now?"

"Of course," Bubble replied, "Two centimeters of 10,000-year-old cold iron is as hard as a dozen centimeters of bulletproof armor." ”

"So strong?"

Luo Chong was overjoyed in his heart, and immediately made up his mind: to continue collecting such ores, he must create a cold iron shield of at least three centimeters, which is equivalent to at least twenty centimeters of bulletproof armor.

With such a shield in front of him, no firearm on earth could penetrate it. Of course, this refers to individual combat firearms, not anti-tank missiles.

Luo Chong's interest increased greatly and he continued to go deeper into this natural passage.

Within half an hour, another piece was picked up, and a larger piece was pulled out from the stone wall, and the total weight of the ore harvested reached 1,000 catties.

Bubbles said that after refining, it would definitely be enough to simply build a shield.

This is a high-purity ore that has been tempered by yin qi for countless years, and a thousand catties of ore can be refined into more than 400 catties of 10,000-year-old cold iron.

After continuing to go deep for half an hour, and pulling out two more pieces from the stone wall, Luo Chong couldn't help but ask: "What are these ores all exposed?"

"If they are not exposed, how can these ores come into contact with the Yin Qi here?"

Bubble smiled: "They were originally just ordinary metal ores, but because they were exposed, they could only mutate into 10,000-year-old cold iron after countless years of refining by the cold qi." If you dig a stone wall and dig in it, you can't find a single piece, so don't think about this cause and effect in reverse. ”

"Understood. ”

Luo Chong walked forward again, but after a few minutes, he heard the sound of rushing water, and when he looked over, the natural passage had come to an end, and in front of him was an underground river channel with open space, with groundwater flowing below, and above was a huge crypt with an incomparably complex spatial structure.

In addition, there are countless holes in the surrounding stone walls, and those holes are still spewing air currents, emitting all kinds of whistling sounds

Luo Chong observed carefully, and seemed to be able to perceive that the division law of those holes implied some kind of mystery, but he couldn't understand it......

"It's not surprising, that's the wonder of nature, and you can think of these holes as a natural yin-gathering array, likely connected to the ocean. ”

Bubbles explained: "It is such a natural array that can transform underground water vapor into cold gas. Of course, this situation is special and difficult to come by. The most peculiar thing is that it is hidden beneath a city. ”

"So, there are only so many 10,000-year-old cold irons?"

Luo Chong looked at the end of the passage, still a little overwhelmed.

"Don't be so greedy, okay. Bubble smiled: "The few pieces you got just now have been tempered over countless years, it can be said that the gold essence within a radius of a hundred miles can be concentrated here, so that such a little thing can be bred Moreover, there is an even more precious wind protection bead." ”

"Yes, you're right. ”

Luo Chong took out a piece of ore of more than two hundred catties from the soul devouring space, and held it in his hand, as easily as someone else holding seven or eight catties of things in his hand: "I should say thank you to this natural treasure, the essence of millions of years has been condensed, and in the end, it has all been given to me." ”

Luo Chong held this ore in both hands and bowed three times to the crypt in front of him, but he was also quite religious.

Bubbles held the Wind Shelter Bead in her hand, but she muttered disdainfully: "Ridiculous gratitude, I must make it clear to you that you only need to plunder the demons, and you don't have to be grateful to anyone or anything." ”

"I'm not a demon yet, I'm a very sunny prostitute. ”

Luo Chong turned around and walked back, struggling with her in his heart.

"No, no, no"

Bubbles rubbed him desperately in the most delicate spot between her legs: "You have to learn quickly, otherwise, I will look very incompetent, and the Demon Lord may blame me." ”

"Leave Him Alone"

Luo Chong smiled and said, "With me here, the old guy doesn't dare to do anything to you." If he dares to punish you, I will punish his son......"

On the way back, Luo Chong was still searching around very carefully, unwilling to miss any cold iron ore by mistake. This natural passage, which could be completed in ten minutes, was walked by him for nearly two hours, and the harvest was only a fist-sized piece of iron ore.

Here, he really looted it.

It was almost eleven o'clock at night, and Luo Chong crawled out of the tunnel and returned to Leng Qiuyan.

She stood in the hall and waited quietly for more than two hours.

"The harvest is great"

Law rushed over and wrapped his arms around her waist with a smile.

Leng Qiuyan pushed him away a little awkwardly, because there were still several core members of the Red Devil Sect in the hall who had been studying the corpse refining array here

"I'm sorry to blaspheme the Holy Maiden. ”

Luo Chong was in a good mood, and immediately bowed and apologized with gentlemanly etiquette.

"Don't make a fuss. ”

Leng Qiuyan said softly: "Go home and rest, I will go to Shanghai tomorrow." ”

As for what kind of gains Luo Chong had after going down, she didn't want to ask more here, and when she turned around, it was okay for the two of them to talk when they got along in private. Anyway, through his happy expression, he knew that the harvest must be not small.

"Okay, I'm home. ”

Luo Chong looked at the time, it was indeed not early, he went home to take a shower, and it was almost one o'clock in the middle of the night when he went to bed.

Then he said to her softly: "You also rest early, don't be too tired, it's not worth fighting hard for this corpse refining array." Looking back, the hardcover manual I gave you is the real goodstuff. ”

"It doesn't matter. ”

Leng Qiuyan nodded: "I and Thorn Head are on the plane at half past three tomorrow afternoon, and we can sleep until noon." ”

There are a group of her subordinates here, and Luo Chong is not good at having too intimate movements, after all, she is still a demon saintess

Even in the Demon Cult, the Holy Maiden represents chastity.

Waving goodbye, Luo Chong drove home, washed and brushed, and it was half past twelve.

An An and Lin Danna had already slept, and Luo Chong was light and did not wake them up.

The two of them are on the plane tomorrow morning, and they have to go to the airport to check their tickets when they get up in the morning, so they are reluctant to wake them up and toss that kind of thing again

Luo Chong sat on the computer chair, his mind and vision turned into the soul devouring space, not wanting to sleep, but to witness Bubbles use the 10,000-year-old cold iron to create a super shield for himself.

In the Soul Eater space, the first step for Bubbles is to refine ore.

Generally speaking, the method of refining metals is to be done by means of high-temperature hot refining, but it is not used in the incomparably wonderful soul devouring space.

You must know that in the Soul Devouring Space, the magic power of bubbles will be increased by a hundredfold, and the purification technique that can only be used for liquids can be increased by a hundred times, and it will have enough effect when applied to metal.

However, spells alone are not enough, and the bubbles have also used the inexhaustible poisonous fog of destruction in the soul devouring space, and adopted a more special method of corrosion and refinement.

"Smash"

Bubbles snorted, and the steel fork in his hand pointed at a piece of ore of more than two hundred catties and released an oppressive spell, and a small puff of destructive poisonous mist fell on the ore.

At this moment, what should have been an extremely hard ore was turned into a pile of powder by a subtle and extremely destructive force.

Whoop......

Under the control of the bubble, the destruction mist quickly rotated around the pile of ore powder, forming a small tornado more than one meter high, sweeping the powder inside and beginning to fully corrode.

Bubbles also explains: "Pure 10,000-year-old cold iron is stronger than the impurities in the ore, and it will only be its turn after the impurities have been corroded." ”

"Understood. ”

Luo Chong understood, as soon as the impurities were corroded, there was only the purest 10,000-year-old cold iron left, and then these iron filings were fused together, and it became pure iron.

There is certainly a lot of loss in this refining method, but the advantage is that the purification is very thorough and the process is very simple.

If such a high-grade metal can be refined with #11 ball technology, even if it can achieve the same purity, it requires a very complex refining process, which can take thousands of times the time.

In the same way, Bubbles refined a few other pieces of ore into pure metal powder, which was almost enough to make a shield

Then, holding a steel fork in her hand, she made a series of gestures in the air, and actually drew a ray of light, condensing an extremely clear line outline in mid-air

She paints in the air

Luo Chong seemed to understand.

The process is also not complicated, as the bubble only outlines a fairly simple shield figure in mid-air, similar to a three-dimensional virtual frame.

Aggregation

Another spell was unleashed, and the metal powder on the platform flowed in reverse like a liquid, pouring into the air and into the virtual frame.

call

The brilliance shone brightly, as if a miniature sun was lit up in mid-air, and the dazzling light woke up Diane and Zheng Xiumin, who were sleeping.

Of course, it was because Luo Chong hadn't taken care of building a house for the two of them in the Soul Devouring Space, and the two slave girls could only 'open air, sleep, and bathe in the open air.

The dazzling brilliance lasted for more than a minute, and then suddenly dissipated, and Luo Chong saw a dark shield suspended in the air.

A rectangular shield, if erected, is one meter three in height and eighty centimeters in width, and the protective area is definitely enough.

The thickness is according to Luo Chong's requirements, reaching three centimeters. Of course, there are also two ring handles on the inner side of the shield.

It's just that the overall appearance of this shield is quite simple and without any decoration.

Bubbles asked, "Little master, I want to decorate it with gold and silver metal, and paint some color or something." ”

"No"

Luo Chong did not hesitate and immediately replied: "In the Earth World Realm, this kind of thing is best to be low-key, emphasizing practicality as the foundation, and does not need any decoration. ”

"But that's too ugly, isn't it?" Bubbles couldn't allow her work to be so shabby.

"At most, you have a very shallow pattern on the surface, and you can choose what kind of pattern you want. Luo Chong smiled: "This is called low-key luxury." ”

"Okay. ”

Bubbles summoned a small cloud of destructive mist, using it as ink, using its corrosive properties to begin painting on the surface of the shield.

A very light layer of cutwork will not affect the protective effect of the shield. If you retouch the shape of the edges, it is much better than a bare curved iron plate......
