If his brain hadn't been broken, it would have been Darkiron. Could it be that the Darkiron was broken and died, but he had the impression that the shattered Darkiron would remain as if it had been armed with Xuanbing or Xuanjia, and would not return to the state it had before it was activated, and would not turn into a liquid like black mercury.

Either way, he felt the key that would change his fate, and he wanted to find it.

He searched in the dark in the courtyard, not daring to light up the lantern. And when the morning light rises, the brutal training will begin here, and he can't let people see what he is looking for. There is a belief that tells him that he is by no means a waste. He will definitely solve this mystery and make himself strong and live in style.

A pair of green eyes suddenly lit up in the darkness, and Tong Hu was startled.

But then, Ah Gou's figure jumped over silently like an arrow, and his body that was originally standing up straight bowed down, prostrate in front of Tong Hu's feet, and said in a muffled voice: "Ah Gou...... Brother ......"

Tong Hu breathed a sigh of relief and whispered, "Ah Dog, can you find the place where you fell after the most stumbling back?"

The dog sniffed, took a few steps to the side, crouched there, and pointed to the ground.

Tong Hu touched it carefully and found the dark iron buried in the dirt.

If you look closely under the moonlight, this is really a piece of blackiron ingot.

Because it was so small, this piece of Darkiron Ingot couldn't be turned into any decent Soldier or Armor. To change a sword, you need at least three times as much black iron, and to change a black armor, it takes at least ten times.

The most unfortunate thing is that it is heavy in its hand, even if the palm is full of true qi, if someone else has already activated this piece of dark iron, this piece of dark iron has no reaction to Tong Hu at all.

Tong Hu smiled bitterly, when he was determined to be the most rejecting Xuantie's physique, his fate fell to the bottom of misery.

No one wants to buy him, even as a coolie. The martial arts arena didn't even plan to sell, but only planned to let him and Ah Gou fight in public, entertain the various sects that came to choose people, and at the same time use his death to inspire other fighting boys. Let them understand that the end of the waste is such a tragic death, let them redouble their hard work.

But fate changed, and Tong Hu clenched the dark iron in his hand.

The dark iron, which could not be reforged, was stained with his blood and turned into a high-purity ingot!

Ah Gou said quietly on the side: "We...... Walk ......"

Tong Hu said sadly: "Forgive me, Dog, I don't have the strength to take you away yet." You have to be patient. Someday I'll take you out of here. Tong Hu spread out his palm, and the small piece of dark iron shone in the moonlight, "This is our secret, the hope of our two brothers, you have to keep this secret." You have to trust me. ”

........................

The Xuanxian Crystal Ore is the mother of all golds, and the most important spiritual treasure that the Xuanwu Realm uses to refine weapons is simply a living spiritual iron, which is extremely difficult to refine. However, it can merge with the warrior, and can be transformed into a soldier or armor according to the warrior's wishes, or any desired form, which is called "armed".

At the same time, the dark iron ore contains the essence of heaven and earth cultivated for thousands of years, called "Xuanling essence", which can give the user several times or even a hundred times or a thousand times the strength of the force, and even change the structure of the body, strengthen the spirit, and make people reborn. Therefore, whether it is martial cultivation or spiritual cultivation, it needs the support of a large number of dark iron materials.

However, this dark iron crystal ore is extremely rare and precious. It is difficult to refining and forging without saying, and there is also an extremely important feature, the Xuanling essence contained in it makes it like a living and living existence.

If the user does not absorb it, but fills his true qi and spiritual energy into the Xuan Ling Essence contained in the Spirit Iron, this Spirit Iron will merge with the user's soul and become the form that the other party desires. Once formed, it will not change.

If this form is destroyed, then this piece of dark iron will be "dead" and become an ordinary mortal iron, and the spirituality will be lost, and no one can repair it anymore. Because the Xuanling Essence is conceived by the Xuantie after trillions of years of absorbing the essence of the Sun and the Moon, the form will be lost if it is broken, and the Lingtie will also become scrap iron with the loss of the Xuantie Essence.

Even if ordinary metal is used to replace the fractured parts, it is difficult to restore the vitality of the dark iron. Although the hardness of mortal iron is still there, it can no longer give the strength of the warrior.

Therefore, each piece of dark iron ore seems to have its own life, and it is as big as it is mined, and it is impossible to fuse two pieces into one, nor can it be forged twice, and its value is precious.

Half a fingernail-sized ingot is worthless, because its weight makes it difficult to make anything powerful. However, in Zhu Ziguo, this can be used as money, and it is better to use it than gold or silver tickets.

Although dark iron is very malleable and can become hollow and thinner than paper, it is only a little bit after all. Ah Dog turned it into his own iron claw, which was very light and thin, less than half a foot long, which was already the limit of extension. Although it is sharp, it is too thin and can be easily broken.

A piece of black iron ingot, the size of a fingernail, is worth five times as much as half a fingernail-sized granule. Because this size can already pull out a sharp knife. It is not so easy to break, and at the same time has some toughness. Although for a true master, this weight is still useless, at most a high-level flying knife, but for many lowly martial artists, such a knife is already a dream.

In Zhu Ziguo, there are dozens of shops that sell or buy this small piece of dark iron, and there are also black markets. Generally, black iron is traded in gold stores because it is a precious metal and is more expensive than gold. Merchants in many countries like to trade black iron as money, because it is easier to carry than gold, and it absolutely retains its value.

Zhu Ziguo is a very special country, the country is very small, there is only one capital, but it is extremely prosperous. The reason is that because Zhu Ziguo is located at the junction of the three countries, it is a transportation artery, and the monarch saw this and established a national policy of always being neutral and tax-free for the Chamber of Commerce, and over time it became a place where merchants gathered. Therefore, Zhu Ziguo is not a powerful country, but it is undoubtedly a rich country, and it is also the place where many countries choose to hold talks, and it is also a gold hole for those who pursue pleasure. At the same time, the people's ** Yi and martial arts arena are also very famous.

"Now the price of twelve taels to twenty taels of dark iron is twenty-two taels of silver for every two taels of black iron, or two taels of gold for every two taels of dark iron. Your piece has fifteen taels, and the purity is quite good. ”
