Rebirth of the Urban Immortal Emperor

Zhang Yifeng couldn't help but walked towards the stove. I don't know if it was an illusion. At this moment, Zhang Yifeng didn't think that the black iron lump was inconspicuous at all. His hand touched the black iron sacred furnace, and he could actually feel a hint of joy and excitement coming from the black iron sacred furnace.

"It is indeed a rare treasure!" Zhang Yifeng exclaimed. The reason why the Black Iron Sacred Furnace conveyed such emotions must have sensed the spiritual fire of heaven and earth in his body.

A forge that can have its own emotions, what is it if not a treasure?

If this is really a forging furnace that can forge holy weapons, it must be said to be a tragedy that it is left here covered with dust.

As he thought, Zhang Yifeng's spiritual energy surged all over his body, like a hurricane blowing through him. All the dust on the black iron sacred furnace was blown away.

The dust was blown away, and a black and shiny forging furnace appeared in front of the three people.

The black iron sacred furnace exudes a faint cold air, like a peerless sword that has been sealed in dust for countless years and is shining again.

Zhang Yifeng flicked his finger on the black body of the black iron sacred furnace, and a melodious buzzing sound suddenly emitted. Like a huge morning bell, it cheers people up.

"Great stove!"

Although Zhang Yifeng was not familiar with the forging furnace, he knew that it was indeed a good furnace.

Seeing the look in Zhang Yifeng's eyes towards the Black Iron Sacred Furnace, Mr. Fu felt extremely happy that he had finally found a good owner for it.

"Come on, I'll teach you the complete art of forging. I say, you do it. Light the black charcoal first."

Zhang Yifeng followed the old man's instructions, put the black charcoal into the bottom of the furnace and lit it. Then he started pulling the blower.

At this time, Mr. Fu took out a bunch of rusty metals from the house and threw them into the black iron sacred furnace. While throwing them away, he began to say: "Actually, the Soul Blood Casting Technique is not that mysterious. Just add a head cut off from a living animal when smelting the material."

Mr. Fu began to explain to Zhang Yifeng the casting method of soul blood casting.

Since this time it was just a practice, no live beast heads were added to the Black Iron Sacred Furnace, and not even a mold was used. The refining molten iron is directly cast into an iron block and then supplied to Zhang Yifeng for forging.

In fact, using the meteor hammer method for forging does not require a mold at all, because any shape can be forged with a flame hammer.

Zhang Yifeng can even make embroidery needles, so what else can't he make?

Half a day passed, and a small dagger gradually took shape under Zhang Yifeng's processing.

When Zhang Yifeng completed the processing, Mr. Fu said with great solemnity: "The next step is the most important step, tempering!"

Zhang Yifeng nodded. Although he had never been exposed to the forging industry, tempering was common sense that everyone understood.

Following the old man's instructions, Zhang Yifeng put the forged dagger back into the forging furnace without pulling the blower this time. According to Mr. Fu, tempering only needs to keep the temperature in the furnace at a higher temperature, and there is no need to raise the temperature too high.

In fact, this is easy to understand. If the temperature is too high, wouldn't it mean that the forged things will melt again, which means that all the previous work will be in vain.

Let the forged dagger be tempered again in the fire for five hours, which is Zhang Yifeng's tempering for one night!

Early the next morning, after the rich man took a nap, he took out something similar to candy from his arms and threw it into a wooden bucket filled with water.

What is extremely miraculous is that after entering the wooden barrel, the "sugar" melts quickly and emits a cold air.

Seeing that Zhang Yifeng was confused, the old man smiled and said: "Real gold is not afraid of fire, but it must not be afraid of water. You should know that when extreme heat is followed by extreme cold, even fine steel will collapse. , but my requirement is that even if the extreme heat is followed by the extreme cold, it must be able to withstand it, otherwise it will be a failed work!"

Zhang Yifeng tried the water temperature in the barrel. It felt freezing to the bone, it was definitely dozens of degrees below zero, but the strange thing was that at such a low temperature, there was no ice at all.

In doubt, he took out the dagger, feeling very uneasy. Of course he knows the terrifying power of thermal expansion and contraction. He was afraid that the dagger he had forged for a long time would not be able to withstand the power of the water refinement and would fall apart.

laugh……

A large plume of white smoke rose from the barrel, making a harsh sound.

Five minutes later, Zhang Yifeng nervously took out the dagger from the barrel.

Fortunately, the dagger was not broken.

"Old man, am I successful?"

The rich old man smiled coldly, took the dagger, and threw it to the ground without even looking at it.

Bang!

The dagger actually shattered like glass.

Even after being tempered thousands of times by Zhang Yifeng, the dagger still could not withstand the dual test of extreme heat and cold.

Forging failed!

Looking at the broken dagger on the ground, Zhang Yifeng's mood suddenly became bad. This was the first time in his life that he had failed like this!

A wry smile appeared on the corner of his mouth, Zhang Yifeng shook his head and said: "Old man, there are not many things that can withstand extreme cold and heat."

The old man snorted coldly and said: "Fart! If something forged by the meteor hammer method cannot withstand extreme cold and heat, it is simply a failure!"

The rich man's voice was sonorous and his face was full of seriousness. This was an expression of an old man's dedication to blacksmithing.

"Don't go back today. Just practice in the backyard for a day. I'll come back tomorrow."

As soon as the rich man finished speaking, he had already left.

"Sister Nan Xin, do you think I'm too stupid?" Zhang Yifeng was inevitably a little uncomfortable after being scolded by the rich old man. This was the first time that Mr. Fu showed dissatisfaction since he followed him.

On the side, Nan Xin shook her head and said: "Brother Zhang, this is your first time forging, so it's normal to fail. Mr. Fu's first time forging, maybe he's not as good as you."

Hearing this, Zhang Yifeng smiled and nodded, and then drove away the depression in his heart.

He is still young and has plenty of time.

The day passed quickly, and early in the morning for the second question, the old man appeared in the backyard again.

The second time he forged in front of the old man, Zhang Yifeng was particularly serious. Because he knew that as long as there was the slightest slack, the things he forged would not be able to withstand the perverted water refining method of the rich old man.

However, what disappointed Zhang Yifeng was that the thing he had spent half a day working on, still fell apart during the water refining process.

The second time, still failed!

Zhang Yifeng finally understood that this Soul Blood Casting Technique was not something he could rush for. It took too long to come out this time. It was time to return to Hangyang City and register at Jingkai University.
