Shaking his head, the Prime Minister smiled bitterly and said, "It's impossible to reduce it. You know... the price of black iron has been reduced to less labor costs."

In fact... the current price of black iron is only half of the investment in mining and smelting. How can it be reduced?

He shook his head with a wry smile, Yan Guilai said, "Forget it, that's true, it's impossible to reduce it. The more you sell, the more you lose money."

After waved his hand, Yan Guilai said, "Okay, I'll just ask about the Black Iron business, but for now, these abandoned equipment and the Black Iron warehouse next to it are all mine."

Nodding, the General Secretary of the Weapon Refining Department said, "You'd better move these things away as soon as possible. To be honest, we have consumed too much energy and labor to keep these abandoned weapons."

After waved his hand, Yan Guilai said, "You all leave. From now on, this place will not be open to the public. At most, I will clear it in one month!"

Nodded, the General Secretary of the Artifact Refining Department waved his hand and took everyone away from the abandoned equipment warehouse.

After seeing everyone off, Yan Guilai couldn't help but take a long breath. With a wave of his right hand, three-legged golden crows with golden flames rose all over his body flew out.

Pointing at the abandoned equipment piled up like mountains and full of pits and valleys, Yan Guilai said, "How about it... your sun fire can be used to refine these abandoned equipment, right?"

Proudly nodded, the three-legged golden crow said, "Of course, my sun is truly fire, everything is not burning, to me... these are just side dishes."

Frowning, Yan Guilai said, "I don't want you to burn all these discarded equipment. In fact... I want you to help me refine these discarded equipment and refine ninth grade mixed iron!"

He glanced at Yan Hui with a strange look, and the three-legged golden crow said, "Aren't you talking nonsense? In fact... When the sun's true fire burns to the limit, it's the ninth grade material. This is common sense, don't you know?"

He looked at the three-legged golden crow in confusion, and Yan came and said, "But, didn't you say... the sun's true fire is ignited?"

Shaking his head, the three-legged golden crow said: "Indeed, even the ninth grade material, the sun's true fire can be burned, but... do you think that burning all substances, speed and difficulty are constant?"

Suddenly, he opened his mouth wide, Yan Guilai said, "I understand, it only takes a moment to burn a ball of cotton, but burning a piece of black ice will definitely not be completed in a moment."

Nodded, the three-legged golden crow said, "If I have enough time, even the ninth grade material, I can use the real fire of the sun to completely burn it to ashes, but... that takes really long."

After calculating slightly, the three-legged golden crow continued: "A piece of nine grades the size of a head must be burned at least 365 days before it can be completely burned to ashes."

He rubbed his hands excitedly, and Yan Guilai said, "What are you waiting for? Hurry up...burn all these discarded equipment for me. I only want the ninth grade mixed iron!"

Faced with the order from Yan Return, the three-legged golden crow flew out quickly. As they flew, clusters of sun fire fell on the mountain of equipment.

Time passes quickly...

A quarter of an hour later, the three-legged golden crow flew over a radius of hundreds of kilometers and lit three thousand ignition points.

Three thousand true sun fires have set up the Fierce Sun Burning Heaven Array. All the materials in the big array will be completely melted after nine hours.

Time passed by minute by minute. With the efforts of Yan Return and the Three-legged Golden Crow, all the equipment soon melted completely, forming a colorful torrent, flowing towards the lowest position in the middle.

While the sun was burning, all the abandoned equipment and the black iron in the warehouse next to it were burned into metal liquids. In the canyon that was as high as 100 meters and in a diameter of hundreds of kilometers, it accumulated into a huge small lake composed of metal liquids.

When nine hours passed, the originally piled up canyon was now empty, only the red lake formed by melting hardware, with curling blue smoke rising.

So far, the smelting has not been completed, on the contrary, it is just the beginning.

As time passed by minute by minute, another nine hours passed.

Within nine hours, the lake where metal melt gathered shrank a large circle, and the metal melt in the lake also refined from first-grade black iron to second-grade hematite!

Every nine hours is one round, and a total of nine rounds of refining are required.

The first round of melting, the second round of refining... Nine rounds passed in a row, and it took eighty-one hours, and finally... the refining came to an end...

Looking around, the metal molten lake, which originally had hundreds of square kilometers, is now only a ten-meter-diameter pool.

Looking at the pool of metal melt, Yan Guilai said excitedly: "Xiao Jin, these should be what you said, the ninth-grade mixed iron!"

With his wings gently flapped, Xiao Jin floated in the air and nodded, "That's right, these are ninth-grade mixed iron. They have been refined to the extreme. If they continue to refine, they will only burn it into pure energy and dissipate it in the air."

Hearing Xiao Jin's words, Yan Guilai did not dare to be negligent. He instantly pinched his fingers with both hands, and swung quickly, the pool of metal melt instantly spun.

Under the control of the return of the swallow, the pool of mixed iron melt gathered into a ten-meter-long metal snake, which was spinning and galloping in the air.

With the rapid rotation, countless gorgeous patterns quickly emerged on the metal melt, one by one, one by one, one by one, one by one, one by one, and one by one, which was beautiful and extremely strange.

Time passed by minute by minute. Under the control of Yan Return, the long metal snake continued to rotate and circle, and quickly began to cool down.

Finally, when the temperature dropped to a certain level, an extremely dark iron rod fell down instantly and hit Yan Guilai heavily.

With the banging sound, the extremely hard ground burned by the sun's true fire was instantly smashed by the pitch-black iron rod.

The huge iron rod, which was nine meters long, was straight in front of Yan Guilai. The extremely cold murderous aura spread violently from the iron rod. Wherever he passed, the ground that was burned red quickly cooled down.

Feeling the boundless murderous aura, the three-legged golden crow couldn't help but shiver, and quickly flapped its wings and flew into Yan Guilai's body to avoid the erosion of the cold murderous aura.

Looking at the dark mixed iron rod in front of him, Yan Guilai was extremely satisfied.

This mixed iron rod is nine meters long and is made of gold, silver, copper, iron and tin, and five elements metal. It weighs 18,000 kilograms!

This mixed iron rod has three characteristics: the highest hardness, the greatest toughness and the heaviest weight!

Apart from these three characteristics, this mixed iron rod has no more characteristics.

However, this mixed iron rod also has its disadvantages. It is made of discarded equipment and has been full of murderous aura on the battlefield for thousands of years. Therefore... normal people cannot use it at all.

Looking at this mixed iron stick, Yan Guilai nodded with satisfaction, but... having a stick alone is not enough.

Originally, Yan Guilai planned to refine two sticks, Yuan Gang and Yuan Hong each.

But I never thought that at the end of refining, the ninth grade mixed iron was only enough to refine a mixed iron rod, which was embarrassing.
Chapter completed!
