Report: This magician says he believes in science

Although the human civilization in this world is backward, they have already mastered the use of coal, which provides the basic possibility for Chu Feng to make iron.

Otherwise, it is impossible to generate a high temperature of more than 1000 degrees by burning ordinary wood.

This sintering is also the most risky sintering. If the internal structure is unreasonable or there are flaws, it is very likely that the entire blast furnace will crack directly, or leak air or heat.

Chu Feng waved to the city lord's soldiers not far away, and signaled them to move the blower to the side of the blast furnace. Then Chu Feng climbed up the ladder by himself, and tightly connected the blower to the air inlet above the blast furnace.

"City Master, you can start lighting the fire." Chu Feng said with a smile.

"Okay!" City Lord Ouyang was also extremely excited at this time.

As a member of the military, no one looked forward to the birth of a brand new ironmaking technology more than him.

Accompanied by a ray of fire, the coal that had already been placed inside the blast furnace was quickly ignited, and the temperature inside the furnace also began to rise slowly.

"You two, turn this roulette." Chu Feng ordered the two guards of the city lord who had been waiting by the blast furnace.

These two are both three-star martial artists, their strength is far greater than ordinary people, and it is easy to turn the disc of the blower.

At this moment, City Lord Ouyang was also staring intently at the inside of the blast furnace.

The two martial artists turned the blower wheel, and then a large amount of air began to be sent into the blast furnace. With a muffled sound of "Peng", the flame inside the entire blast furnace suddenly rose by more than half a meter.

"Huh?" Seeing this, City Lord Ouyang's eyes brightened immediately, and he exclaimed: "Master Chu, what you said is indeed true, air can support combustion, and the flame in the stove is even bigger!"

I saw that the dark red coal inside the blast furnace suddenly turned almost transparent red, and waves of heat gushed out directly from the inside of the blast furnace.

The temperature of the entire blast furnace also began to soar rapidly, and the entire furnace body also began to make a faint sound, and the final sintering was in progress.

Beside the blast furnace, City Lord Ouyang already knew that Chu Feng's magical technique had already succeeded for the most part.He glanced at Chu Feng silently, the shock in his eyes became more and more intense, and he couldn't help but said: "Master Chu, I didn't expect you to really succeed in creating this four-star magic."

Chu Feng smiled slightly when he heard the words, and said: "City Master, don't worry, the final sintering of the entire blast furnace will last for more than half a day, and an ultra-high temperature test will be carried out at the end. If there is no problem, it can be said to be successful."

City Lord Ouyang nodded repeatedly when he heard the words, but his eyes were fixed on the blast furnace for a moment, as if the flames inside the blast furnace possessed extraordinary magical power.

Seeing this, Chu Feng shook his head and laughed.

However, to be honest, Chu Feng felt a little proud at this moment.

After all, he is just an ordinary college student. Although he knows some basic principles and has made some ideas, it is actually the first time to manufacture a blast furnace in kind.

At this moment, Chu Feng was full of a sense of accomplishment when he succeeded once.

After more than half a day of high-temperature sintering, the performance of the blast furnace was finally basically stable. Finally, Chu Feng gave an order, and several city lord's personal soldiers moved the miscellaneous iron billets prepared in advance.

This kind of miscellaneous iron is formed after simple sintering of iron ore. Not only is it not hard, but it is also brittle, but it is already the most mainstream ironmaking technology in the world.

The ironware used by Ouyang City Lord and the others was actually hammered out manually on the basis of these miscellaneous iron pieces.

Although beating at high temperature can effectively remove the impurities inside the miscellaneous iron, and finally obtain hard pig iron.But this efficiency is ridiculously low, and the quality of the pig iron obtained in the end is also very poor.

Even so, the high-temperature beating technology of ironware is still a "top secret" in this world, and it is extremely rare in a third-class city like Tianyang City.

At this time, the iron-making blast furnace built by Chu Feng has a high enough temperature, coupled with the participation of the internal coal in the chemical reaction, it can quickly melt the iron inside the miscellaneous iron, remove the impurities, and finally obtain molten iron.

"City Master, look, it's melting, the iron is really melting!" A soldier who had been waiting by the blast furnace suddenly shouted.

City Lord Ouyang's eyes brightened immediately when he heard the words, and he rushed to the side of the blast furnace immediately, his eyes staring like copper bells, regardless of the danger.

But at the level of a blast furnace, red molten iron slowly flows out of the drainage trough specially designed by Chu Feng, exuding amazing heat.

"Successful!" Seeing this, Chu Feng finally breathed a sigh of relief, and said with a smile, "Master Ouyang, the molten iron will flow into the pre-made mold, and finally solidify into iron bars. After simple forging It can be made into a weapon by hitting it, and the texture should not be too bad."

"Yeah." City Lord Ouyang looked at the red molten iron at this moment, no longer cared about thinking about Chu Feng's words, and just nodded.

"God, I never thought hard iron could turn into water!" City Lord Ouyang only felt that his worldview had been subverted.

If he hadn't been in a high position all the year round and developed a calm temperament, at this moment, City Lord Ouyang would probably scream.

Seeing that molten iron was successfully boiled in the blast furnace, Chu Feng felt relieved.

At this time, the molten iron flowing out has very few impurities inside. After cooling, it will be the simplest cast iron. Although the quality is quite rubbish in the eyes of modern people like Chu Feng, it has already surpassed the understanding of other people in this era. .

"By the way, remember to add charcoal to it in time, and shut down the furnace after half a day, and wait a day before turning it on again."

"City Master Ouyang, after the iron bars in the mold have completely cooled down, you can use them to make weapons." Chu Feng explained a few words before turning and leaving Shenting Square.

Things are already on the right track, and it would be a waste of time for Chu Feng to stay here and wait.

However, City Lord Ouyang did not leave. At this moment, he was full of curiosity and anticipation. He could vaguely feel that if the quality of the finally cooled iron bars was really as Chu Feng said, far superior to the current ironware of the Tang Dynasty, then this This magical technique will definitely change the status quo of the entire Tang Dynasty!

"It's terrible. Master Chu is worthy of being a person favored by gods. He has the skill of turning iron into water." City Lord Ouyang sighed in his heart.

After Chu Feng left Shenting Square, he went straight back home, impatiently took out the seeds or roots of the medicinal materials he had bought before, and then entered the system space.

"Some of these seeds have dried up, and I don't know if they are useful." Chu Feng muttered.

But now, he can only hold the mentality of giving it a try. If these dry seeds and roots cannot grow medicinal materials, he can only find opportunities to go out of the city to find fresh medicinal materials.

And there are a lot of zombies and beasts outside the city. Although Chu Feng is much stronger than ordinary people, he doesn't want to take risks.

After soaking the medicinal seeds with the spiritual spring, Chu Feng buried the seeds and roots in the soil and poured a lot of spiritual springs before leaving the system space.

While Chu Feng was having nothing to do at home, the first batch of completely cooled iron bars finally arrived in Shenting Square.

Seeing that the city lord Ouyang has completely lost the pretensions of the city lord at this time, he rushed to the first one and scraped away the soil for making the mold with his hands, and then carefully took out an iron bar about one meter long.

As soon as the iron bar was in hand, the head of Ouyang City Lord felt a "hard" feeling from the iron bar, and he couldn't help shouting: "Get the knife!"
