Chapter 405: Still fail

Zhang Yifeng involuntarily walked towards the stove, not knowing that it was not an illusion, at this moment Zhang Yifeng actually did not feel that this black iron knot was insignificant. He touched the black iron sacred furnace with his hand, and he could actually feel a hint of cheering and joy from the black iron sacred furnace.
"Sure enough, it is 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.
What is a forge that can have your own emotions if it is not a treasure?
If this is really a forging furnace that can forge sacred artifacts, it would be placed here covered with dust, it must be said to be a kind of sadness.
As far as his thoughts came, Zhang Yifeng was full of spiritual energy, like a hurricane. The dust on the black iron holy furnace was blown off.
The dust was blown off, and a black and shiny forge appeared in front of the three of them.
The Black Iron Sacred Furnace exudes a faint chill, like a peerless sword that has been sealed in dust for countless years, blooming again.
Zhang Yifeng's finger flicked on the black body of the black iron holy furnace, and a melodious buzzing sound suddenly appeared. It's like a huge morning clock, refreshing people.
"Good furnace!"
Although Zhang Yifeng is not familiar with forging furnaces, he also knows that it is indeed a good furnace.
Seeing Zhang Yifeng's eyes on the black iron holy furnace, the rich man was very pleased and finally found a good master for it.
"Come on, I will teach you the complete forging technique. I said, you do. First light the black charcoal."
According to the instructions of the old man, Zhang Yifeng put the black charcoal into the bottom of the furnace and lit it. Then he started to pull the blower.
At this time, the rich old man took out a pile of rusty various metals from the house and threw it in the black iron holy furnace. But when you smelt the materials, add a head cut from a living beast."
The rich man began to explain the casting method of soul blood casting to Zhang Yifeng.
Since this time it was just a practice, no live beast head was added to the black iron holy furnace, and even the mold was not used. The refined molten iron is directly cast into an iron block and then supplied to Zhang Yifeng 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 be made.
After half a day, a small dagger gradually took shape under Zhang Yifeng's processing.
After Zhang Yifeng finished processing thoroughly, the rich man said very solemnly: "The next step is the most important step, tempering!"
Zhang Yifeng nodded. Although he has never been in the forging industry, tempering is common sense that everyone knows.
Following the old man's instructions, Zhang Yifeng put the forged dagger back into the forge, this time without pulling the blower. According to Mr. Fu, tempering only needs to keep the temperature in the furnace at a higher temperature, and does not need to raise the temperature too high.
In fact, this is also easy to understand. If the temperature is too high, wouldn't it mean that the forged things will be melted again, which means that all the previous work will become useless.
Let the forged dagger be tempered in the fire for five hours again, that is, Zhang Yifeng tempered for a night!
In the early morning of the next morning, the rich man took a nap, then took a candy-like thing from his arms and threw it into a wooden bucket full of water.
What is very strange is that after entering the wooden barrel, the "sugar" quickly melted and exuded a chill.
Seeing Zhang Yifeng a little puzzled, the old man laughed and said: "True gold is not afraid of fire to refine, but in the same way, it must not be afraid of water refining. You should know that after extreme heat and then encounter extreme cold, even fine steel will collapse , But my requirement is that even if you suffer from extreme cold after extreme heat, it must be able to withstand it, otherwise it will be a failed work!"
Zhang Yifeng tried the temperature of the water in the wooden barrel. It feels like frozen bones, definitely dozens of degrees below zero, but what is strange is that there is no ice at such a low temperature.
In doubt, he took out the dagger, feeling very nervous. Of course he knew the terrifying power of expansion and contraction. He was very afraid that the dagger he had forged for a long time, could not withstand the power of water refining, and it would break into pieces.
laugh……
A large puff of white smoke rose from the barrel, making a harsh sound.
Five minutes later, Zhang Yifeng took out the dagger from the barrel very nervously.
Fortunately, the dagger was not broken.
"Master, am I successful?"
The rich man smiled coldly, took the dagger and threw it on the ground without even looking at it.
Cack!
The dagger shattered like glass.
Even after Zhang Yifeng's thousands of tempers, this dagger still couldn't withstand the dual test of extreme heat and extreme cold.
Forging failed!
Looking at the broken dagger, Zhang Yifeng's mood instantly became bad. He has been a human for two lives, this is the first time he has failed this way!
A wry smile appeared at the corner of his mouth, and Zhang Yifeng shook his head and said, "Master, there are not many things that can bear the extreme cold and extreme heat."
The old man snorted coldly and said, "Fart! What is forged by the meteor hammer method, if it can't even bear the extreme cold and extreme heat, is simply a failed work!"
The rich man has a sonorous voice and his face is full of seriousness. This is an old man's dedication to forging.
"Don't go back today, just practice in the backyard for a day, and I will come again tomorrow."
The rich man's words fell, and the man had already left.
"Sister Nanxin, do you think I am too stupid." After being trained by the rich man, Zhang Yifeng inevitably felt a little uncomfortable. This is the first time he has shown dissatisfaction since he followed the rich man.
On the side, Nan Xin shook her head and said: "Big Brother Zhang, you are forging for the first time, and failure is normal. The first time the rich man forges, maybe it's not as good as you."
Hearing this, Zhang Yifeng smiled and nodded, and then he drove out the bitterness in his heart.
He is still young, and there is time.
One day passed quickly, and the old man appeared in the backyard early in the morning for the second question.
For the second time in front of the old man, Zhang Yifeng was very serious. Because he knew that as long as there was the slightest slack, the things he forged could not withstand the abnormal water refining method of the rich man.
However, what disappointed Zhang Yifeng was that the things he had spent half a day quietly creating were still broken during the refining process.
The second time, it still failed!
Zhang Yifeng finally understood that this soul blood casting technique was not something he could eagerly seek. This time it took too long to come out. It was time to return to Hangyang City and report to Jingkai University.
