After a pretty hearty vegetarian meal, I couldn't prepare for the sword casting.

Those strange rituals also attracted the ideas of Gu Yu and others. They had never seen sword casting, nor the rituals before sword casting, so everyone stood quietly and watched with interest.

Speaking of the rituals before the sword casting were very complicated, and everyone was dazzled. It was a furnace, a sacrifice to the fire deity star king, and a ancestor, etc. There were as many as a dozen sacrifices. It was not until all these things were sacrificed, so I couldn't walk aside and took out a piece of clay from the large wooden cabinet.

"Gu Yu donor, how long is the Qiankun Liuhong Sword? What is the width of the sword? What is the image?"

Gu Yu thought for a while and said, "The Qiankun Liuhong Sword is three feet and six inches long, and is one inch and eight inches wide. It is half of the Tiangang that are strong but not light and agile. The sword body is engraved with the Demon-breaking Seal Text."

Unable to ponder for a moment, nodded, and began to knead the clay according to Gu Yu's words.

Not long after, it was formed into a casting model. The sword model in that model was somewhat similar to the image of Gu Yu's Qiankun Liuhong Sword.

The model was unable to rest for a while, and then it was placed in the baking room next to the furnace to dry the model into molding.

When all this is done, I can't take out a large wooden box full of runes with respect.

Gu Yu leaned over and asked in confusion: "Master, is Xuanbinghan Iron? Why do you need to use this big wooden box full of runes to hold it?"

Unable to nod, he said, "The strong cold iron and even cold things, this cold air can be frozen for thousands of miles. This wooden box is made of fire phoenix and yang. The fire energy burns all things, but it cannot burn this Wutong wood. It can be seen that the toughness of this Wutong wood, the most yin and yang, is mutually generated and restrained, not only blocks the cold air of Xuanbing cold iron, but also allows the Xuanbing cold iron to absorb the fire energy on the Wutong wood to neutralize it. It is the doctrine of the mean and it will be of great help to future forging."

Gu Yu nodded thoughtfully: "So the runes on this are also used as seals?"

Unable to smile and said, "Yes, that's right, this seal is a seal rune. Unless there is a spell to unseal, everything will be difficult to invade."

Gu Yu raised a smile on his lips, but he was very excited, "Master, isn't this only one of these seal runes?"

He couldn't shake his head and said, "Realistically, the seal runes are different because of the different people who seal them."

Hearing that he could not say this, Gu Yu felt a little disappointed. He originally thought that he could break the seal rune here, and in the future, he could break the seal rune in the steel cage where the Jiuxian was imprisoned, so that he could rescue Jiuxian.

"Although that's it, most seal runes are the same as each thousand times, and they are generally the same."

If you can't, you will pull Gu Yu from the abyss of loss to the clouds. He hurriedly said, "Master, the spell to remove the seal should be the same as that."

Unable to nod, he said, "Yeah, it should be almost the same."

Gu Yu couldn't help but be overjoyed, and he hurriedly said, "Master, can you teach me the spell to unseal so that I can save my master?"

Unable to smile and said, "What's wrong with this? Anyway, this mantra to unseal the seal is not a secret method."

Gu Yu said gratefully: "thank you, Master."

Unable to smile and said, "This mantra for lifting the seal is not difficult. "Since the teeth, the gold is better than the gold. I will now unleash the gold for you, and I will never make gold for you. Auspiciousness is auspiciousness, auspiciousness is auspiciousness, and there are pearls and glasses at the Polo meeting. All enemies turn into auspiciousness, and Mahaprajna Rami can relieve all suffering and break it."

Gu Yu recited it silently several times in his heart, and after writing down the mantra for untied knots, he said gratefully: "Thank you, Master, I've recorded it."

Unable to nod, he said, "It's just a little effort, why thank you. I'm going to lift the spell of this wooden box. At that time, there may be a strong cold air to attack your body. You stand far away and avoid being hurt by the cold air."

Gu Yu and Ji Feng nodded slightly and took a few steps back

I could not hold the sycamore wooden box in my hand, and I muttered something in my mouth. As the spell in his mouth suddenly rose, the golden light on the sycamore wooden box was huge. After a moment, the wooden box opened automatically with a click, and a few pieces of cold gold and iron appeared in the wooden box.

In an instant, a cold air came straight towards us. The originally scorching forging moment suddenly dropped. Gu Yu, who was standing not far away, felt his whole body tremble. A breath of cold air invaded his body, causing a trace of fear that fell into the cold pool.

"So amazing, worthy of being the king of cold iron." Gu Yu shivered and murmured.

"Brother Yu, the Qiankun Liuhong Sword cast from Xuanbinghan Iron must be very powerful. The cold air alone is enough to shock others." Ji Feng said tremblingly.

"Yes, but how to forge such a cold Xuanbinghan iron? I'm afraid the average temperature will not melt it at all." Gu Yu said with some concern.

Mole smiled slightly and said, "Don't worry, my junior brother loves forging so much. Now he is planning to use this Xuanbing Cold Iron to forge swords. Naturally, there is a way to melt him. You just wait and see the show." As he said that, he hugged his hands with a comfortable face and looked at him with a smile.

Unable to hold the sycamore wooden box in his hand, but under the thick cold air, he was not injured by the cold air, but he had an unusual excitement on his face.

"Today I will finally forge you, haha, this is my long-cherished wish. Don't worry, I will definitely cast you into a peerless sword and let your light shock all the magic weapons in the world." I couldn't smile on my face, and then solemnly sent the Xuanbing Cold Iron into the furnace

Perhaps because the black ice cold iron is too cold, the heat of the entire furnace seems to be captured by the cold air, the fire is floating and the fire is dim.

After being unable to put the Xuanbing Cold Iron into the furnace, I walked to the other side and started to stimulate the bellows.

Puff

He was unable to show his powerful arm strength again, and the huge bellows were buoyed by him. As he could not speed up the agitation, the temperature in the furnace gradually increased.

Feeling the temperature gradually increased, everyone leaned forward just to see the situation in the furnace clearly

As the temperature continues to rise, the flames in the furnace also increase.

Unable to wait until the temperature rises, a huge bellows are pulled out from the left hand, pulling both hands together, and the wind suddenly increases again, and the temperature in the furnace rises sharply

Even Gu Yu and others couldn't bear the agitation of the heat, and sweat flowed down their foreheads.

But even so, the mysterious ice cold iron still shows no sign of melting

When the temperature in the furnace stabilized, I couldn't look at Ji Feng and Gu Yu and said, "Gu Yu donor, Ji Feng donor, can you do me a favor?"

Gu Yu and Ji Feng looked at each other, nodded slightly, and said, "Master, please speak."

Unable to nod: "Help me pull the bellows and keep the temperature of the furnace as hot as it is"

Gu Yu and the other agreed to unblock the bellows, one left and one right, and then started to pull up the bellows.

As the bellows stirred, the flames in the furnace kept beating, appearing very unstable

However, after Gu Yu and Ji Feng made a slight adjustment, the temperature in the furnace stabilized.

Nodded in satisfaction, bypassed the two of them, came to the big wooden cabinet, and took out several boxes from it, each box filled with different forging materials.

It is impossible to pick a small piece of lead from one box, and then pick a piece of tin from the other box that is equivalent to a quarter of the size of Xuanbinghan iron.

After choosing, you cannot add these things to the crucible in the furnace.

Gu Yu was sweating profusely when he pulled the bellows, but his eyes were staring at the inability to move. Seeing that he could not add these things to the furnace, he asked interested: "Master, isn't it enough to make a sword with only Xuanbing and Cold Iron? Why do you need to add lead and tin?"

Unable to smile and said, "Sword casting is not as simple as you think. Each sword casting link is quite important. Adding tin can increase the hardness and strength of the sword accordingly, but it cannot be added too much. The limit of the tin content over-combination will make the sword body very fragile and easy to break and add a small amount of lead into it, which can adjust the casting and processing properties of the metal. However, the high lead content will also reduce the hardness and strength of the alloy, so these things are indispensable and cannot be added too much."

Gu Yu nodded slightly and said, "So that's the case. If you just pass, you will be broken, it makes sense."

He couldn't take a look at the situation in the furnace, but saw that Xuanbinghan iron had not moved any time, and there was no sign of melting. He couldn't help but frown slightly

Seeing that he couldn't look bad, Gu Yu whispered: "Master, what's wrong with you?"

Unable to shake his head slightly and said, "It seems that I have underestimated the strength of this Xuanbing Cold Iron. No, you have to increase your strength and increase the temperature of the furnace."

Hearing that he couldn't say that, Gu Yu looked at Ji Feng and said, "Ji Feng, I will shout one, two, three in a while, and I will use my strength at the same time to speed up the pace."

Ji Feng nodded slightly and said, "Okay."

So as Gu Yu counted, the two of them increased their strength together, and the bellows began to send the wind into the combustion furnace at the bottom of the furnace. Suddenly, the temperature in the furnace increased.

The temperature of the entire forging room rose again. The fierce temperature was grilled, Gu Yu and Ji Feng were sweating profusely, and they felt as if they were sucked out of the water.

The Xuanbing Cold Iron in the furnace finally began to melt under this violent high temperature, and streams of black smoke flew out of the Xuanbing Cold Iron under the severe high temperature.

"Not bad, keep this temperature, the charcoal impurities in the black ice cold iron have been precipitated." I couldn't rub my hands with some excitement.

But before I could be happy for a while, my face became a little gloomy

"No, still no, the temperature is not high enough, only charcoal impurities have been precipitated, and the black and cold iron has not melted, which has increased the wind."

I can't say that, the two of them increased the bellows again

Even so, the black ice and cold iron in the furnace still remains unchanged

Until the two of them pulled the bellows and reached the maximum wind force, the black and cold iron only melted a little.

"How could this happen? How could it not melt? No, right..." I was so gloomy that it was about to rain. I was pacing around in the furnace with some chaotic look.

"What is the reason? The temperature is not enough? It shouldn't be. This furnace can reach a high temperature of several thousand degrees after my improvement. Now the wind has reached the maximum. The furnace should reach the highest temperature. What kind of gold and iron can be refined? Why can't the Xuanbing Cold Iron be refined? Why is this..."
