Old Man Zhou didn't want to play the piano to the cow, and he didn't bother to explain in detail.

Liu Yifeng nodded and said, "Old man, what you mean is that this iron lump is very awesome." ”

"That's nature. ”

"Really?"

Liu Yifeng was still skeptical, and as he spoke, he walked towards the black iron bump and touched his hand, and at that moment he was surprised to find that he could actually feel a trace of joy coming from the black iron holy furnace.

Liu Yifeng exclaimed. The reason why the Black Iron Holy Furnace transmitted such emotions was definitely stimulated by the fire attribute aura in his body.

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

However, it has to be said that it is a pity that such a powerful forging furnace is placed here and covered with dust.

As far as his mind went, Liu Yifeng's aura was full of energy, like a hurricane blowing. All the dust on the Black Iron Sacred Furnace was blown off.

The dust was blown off, and a black, shiny forge appeared in front of the trio.

The Black Iron Sacred Furnace exuded a faint chill, as if a peerless sword that had been sealed in the dust for countless years was shining again.

Liu Yifeng's fingers flicked on the black body of the Black Iron Holy Furnace, and suddenly let out a melodious humming sound. It's like a huge morning bell, which makes people feel refreshed.

"Good furnace!"

Liu Yifeng's eyes lit up.

Looking at Liu Yifeng's eyes on the Black Iron Holy Furnace, Old Man Zhou was extremely relieved in his heart, and finally found a good owner for it.

Liu Yifeng didn't ask Old Man Zhou about the origin of this black iron holy furnace, everyone has their own secrets, and everyone also has a glorious moment.

Presumably, this black iron holy furnace is the same, its most glorious moment should be the moment when it forges that awesome weapon.

Next, Old Man Zhou took out a pile of rusty metals from the house and threw them into the Black Iron Holy Furnace.

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

"Actually, the Soul Blood Casting Technique is not so mysterious, but when smelting materials, you can add a head cut off from a living beast. Old Man Zhou began to explain to Liu Yifeng the casting method of the Soul Blood Casting Technique.

Since this was just a practice, he didn't add a living beast head to the Black Iron Sacred Furnace, and he didn't even use a mold. The molten iron is directly cast into an iron block, and then supplied to Liu Yifeng for forging.

In fact, using the meteor hammer method to forge does not require a mold at all, because any shape can be forged with a flame hammer. Liu Yifeng can even create embroidery needles, so what else can't be created.

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

When Liu Yifeng finished the thorough processing, Old Man Zhou said very solemnly: "The following is the most important step, tempering!"

Liu Yifeng nodded, although he didn't know anything about forging, but tempering was common sense that everyone understood.

According to the old man's instructions, Liu Yifeng put the forged dagger back into the forging furnace, and this time did not pull the blower. According to Mr. Zhou, 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 also very understandable, if the temperature is too high, it will not melt the forged things again, which means that all the previous work has become useless.

After letting the forged dagger be tempered again in the furnace fire for an hour, Old Man Zhou took out something similar to sugar from his bosom and threw it into a wooden bucket filled with water.

What is extremely strange is that after the "sugar" enters the wooden barrel, it quickly melts and emits a cold air.

Seeing that Liu Yifeng was a little puzzled, Old Man Zhou smiled and said: "Real 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 even steel will crumble if it is extremely hot and then extremely cold, but my requirement is that even if it is extremely hot and then extremely cold, it must be able to withstand it, otherwise it will be a failure!"

Liu Yifeng tried the temperature of the water in the barrel. I feel like my bones are frozen, there are definitely dozens of degrees below zero, but the strange thing is that under such a low temperature, there is no freezing.

In confusion, he took out the dagger, feeling very worried. Of course, he knew the terrifying power of thermal expansion and contraction. He was afraid that the dagger he had forged for so long would not be able to withstand the power of water refining, and would directly shatter it.

Laugh at......

A large puff of white smoke rose from the barrel with a screeching sound.

Five minutes later, Liu Yifeng took out the dagger from the barrel with great nervousness.

Fortunately, the dagger did not break.

"Old man Zhou, I've succeeded, right?"

Old Man Zhou took the dagger and threw it on the ground without even looking at it.

Quack!

The dagger shattered like glass.

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

Forging failed!

"You must know whether you have succeeded in forging or not, not by looking at the surface, but by using it directly. ”

Looking at the dagger that was shattered to the ground, Liu Yifeng instantly had an expression of broken eggs. It took him half a day to forge it. A wry smile appeared on his face, and he spoke: "Old man, your water refining method is too perverted, extremely cold and extremely hot, there are not many things that can withstand it at all. ”

"What do you know! What is forged through the Meteor Hammer Method, if it can't withstand even the extreme cold and heat, it is simply a failed work!" Old Man Zhou's voice was sonorous, and his face was full of seriousness, this was an old man's persistent expression of forging techniques.

"Okay, your way is still far, I'm sleepy when I go back first, it's time to sleep, you come back tomorrow. ”

After opening from Old Man Zhou's house, Liu Yifeng's mood was not very happy, he has always prided himself as the pride of the sky, and even the unfathomable formation has nothing to hide in front of him, and he can grasp the essence, but forging weapons is not the same as practicing formations, one needs to be understood: understanding. One needs to be refined: precision.

Obviously, the failure of the first forging made Liu Yifeng's self-esteem a small blow.

"Master, I'm hungry, and my little brothers are dying. ”

At this moment, Liu Linger's voice appeared in her mind.

Liu Yifeng's thoughts penetrated into the Qiankun bag, and he found that Liu Ling'er's group of zombie brothers were all sticking to the ground, as if they were dead.

These days, Liu Yifeng rarely looks for blood for this group of zombies, and it is troublesome enough to feed Liu Ling'er blood, and it is really a drag to bring this group of zombies.

"Alright, I'll take a trip to the Forest of Terror. ”
