Chapter 1504: Open the furnace (below)

At this time, the high platform on which the sword furnace was cast was no longer flat, but a series of grooves appeared. These grooves surrounded the sword furnace and reached the base of the sword furnace, and continued to extend at the invisible bottom.
Without Tang Banqing's introduction, Lin Tian has already guessed that the role of these grooves must be used to divert the molten iron in the sword furnace. The molten iron follows these curved grooves, and finally converges in a sword-shaped mold. When the molten iron solidifies in the mold, a sword blank is formed.
After the sword blank is forged a thousand times and then quenched, the main process of casting the sword is basically completed. Of course, this is the general process of casting swords that Lin Tian learned from ancient books. As for the skills of the sword masters, he is not clear.
"Lin Tian, ​​come here and stick the town fire charm to the south of the sword furnace." Tang Banqing took out a wooden box and motioned to Lin Tian to stick the charm.
This wooden box has been seen by Lin Tian. It contains the Zhangjiamu Charm. After he opened it, he took out the townfire Charm, and then calculated the orientation with the sword furnace as the center, which was exactly the front of the sword furnace.
Lin Tian took the town fire charm and patted it on the sword stove just after it was pasted. The rune paper flashed suddenly, and a fiery red light burst out. In the light, there was a faint flaming bird spinning, fire The feathers of the bird's body were burning with red flames.
Seeing this flamingo, Lin Tian flashed a noun in his mind-Suzaku. Suzaku is one of the four elephant beasts. It is located in the south and controls the flames.
The red light just flashed away, and then the entire sword furnace followed, and it also flashed red light. After a few flashes, the red light did not enter the furnace body and disappeared.
"Townfire Rune can condense the firepower and protect the sword furnace from being burned. This time the sword is made." Tang Banqing nodded in satisfaction when the Town Fire Rune took effect.
Tang Banqing took another step forward and said to Lin Tian, ​​"Okay, now go to the ground fire channel and heat the sword furnace."
Lin Tian has already seen the way to open the ground fire channel. Tang Banqing opened it once when the deformed stone was last checked. He approached the sword furnace, looked closely, and found the mechanism turned on.
Reach out and press hard, a few clicks sounded, and then the whole underground space was shaken, and the sound of "banging" came out of the ground, accompanied by the "click" of the agency.
The temperature in the basement, which was originally sweltering, gradually increased, and the entire underground space became a sauna. However, the people present were all masters, and this temperature would not become an obstacle, and even sweat did not come out.
The vibration and noise gradually became smaller. At the same time, red light appeared inside the sword furnace, and the red light became more and more abundant, as if a flame was flowing.
Tang Banqing walked around the sword furnace, and even felt the temperature on the furnace with his hands. It seemed to be almost the same, and he said to Lin Tian, ​​"Lin Tian, ​​throw the carbon crystals in."
Lin Tian is still familiar with carbon crystals. The fuel used in refining was carbon crystals. The temperature at which carbon crystals burn is extremely high, and it is very stable and easy to control. It is a superb fuel.
He glanced at the several boxes underground, and in one of them he saw the black and black carbon crystals, the texture was like top-quality black jade. Lin Tian grabbed a few pieces and threw them into the mouth of a faucet.
With the investment of carbon crystals, the red light in the sword furnace changed into a faint purple flame. The emergence of the purple flame caused the temperature in the furnace to rise again.
"Add more." Tang Banqing shouted again, Lin Tian grabbed a few pieces and threw them in again. With such continuous input of fuel, in a while, a large box of carbon crystals was used up, and the flame in the furnace had changed. Pure purple, the temperature is even more terrible.
Lin Tian noticed that every time the carbon crystal was put in and the temperature increased, the town fire charm quickly flashed a red light, and every time it flashed, the temperature in the sword furnace rose rapidly.
Sure enough, as Tang Banqing said, the town fire charm can condense the firepower, the ground fire, the town fire charm, and the carbon crystals burned. Under the combination of the three, the temperature in the furnace is getting higher and higher.
"Try the temperature," Tang Banqing said again.
Lin Tian hesitated and said, "How to try?" His first reaction was, did he try? There is no thermometer here.
Tang Banqing glanced at him, then pointed to one of the boxes: "That's an alloy iron ingot, throw it in and see."
This is the case, Lin Tian Dawu, this is the trial method. He picked up an alloy iron ingot, felt slightly heavier, and the weight was not light, and then cast it in from a faucet.
Lin Tian opened the super perspective, and observed the alloy iron ingot. The iron ingot encountered the flame, and the outer layer melted in the blink of an eye. The entire alloy iron ingot did not stand for ten seconds, and all of them were announced to be melted.
The molten molten iron flowed to the bottom of the sword furnace and flowed out of the groove. Tang Banqing pressed on the ground, a groove suddenly changed course, and the molten iron also flowed to another place.
It was a bǐshǒu-shaped mold groove. The red molten iron flowed into the mold. After cooling, the sword blank became.
"Take it out for forging and feel the intensity." Tang Banqing guided again, just like teaching his disciples to follow the temptation.
A famous teacher instructed that Lin Tian of course sells mechanics. Take out the sword blank with iron tongs and place it on the anvil. At this time, the sword blank is still dark red. He recalled the forging methods recorded in the book, and started to fight.
Others saw it interestingly, except that Ling Shuiyao was bored ~ EbookFREE.me ~ She came to see the birth of the Excalibur, who knew it was on-site teaching.
Lin Tian's forging speed and intensity are incomparable to others. Very soon, bǐshǒu, the length of the palm of his hand, was formed. Tang Banqing opened a stone slab, which was actually clear spring water, which was still flowing slowly. Obviously, there was a culvert in the ground. It's not clear where this spring water comes from.
Under the understanding of the heart, Lin Tian put bǐshǒu into the water, and a sound of whistle erupted.
"Well, it's not bad for the first time." Tang Banqing took over bǐshǒu, looked around a few times, and quite appreciated: "It's time to start."
As soon as I heard it started, Ling Shuiyao, who was still listless, looked energetic, and Lin Tian also stretched his heartstrings. This time the sword was tolerated, otherwise the rare materials would be discarded, and such a superb might never be found in the future. s material.
"Guimaru breaks the knife and throws it in." Tang Banqing said simply.
Lin Tian picked up the two cutting blades of Ghost Pill and threw them in. The Ghost Pill came into contact with the flame. The decoration of the knife handle was instantly incinerated and disappeared, but the main part did not melt like the iron ingot, but it turned red quickly.
"Add another carbon crystal ..."
Lin Tian cast in according to the words, the flame suddenly burst, and the octagonal faucet also inhaled a stream of air, forming eight flame streams in the furnace, and the flame immediately wrapped the ghost pills.
"squeak……"
The abnormal sound suddenly came out of the flame ball. The sound was sharp and harsh, making people's ears numb, and even made people feel j skin 几. Several people zhōnggōng weakest Ling Shuiyao even took a step back.
