Lin Tian looked at the sword furnace, his eyes seemed to penetrate the base, and in his mind flashed the sword-casting method described by the girl zombie, and he couldn't help saying: "Sky Thunder and Earth Fire ..."

The ghost blinked, looking at Lin Tian, ​​and said strangely, "Ten brother, you are talking about men and women together, rub out sparks, and then give birth to something shǎoérbùyí, indescribable. This is called the thunder to stir the fire ... ⒉ "

"Fuck, I despise you!" Lin Tian glanced at him and gave him a middle finger.

"Hehe, this guy is right. Men are doing it, they are heaven, women are Kun, they are earth, heaven and earth meet Thailand, men and women are meeting, and they are fighting for heaven and earth." Tang Banqing grinned twice, very serious. Said quietly.

The three Lin Tians heard black lines all over their faces, and the old woman was too direct.

"Ground fire is actually underground magma flow," Yun Xiaotian interrupted.

"Hey, when it comes to ideas, Xiaotian is still a civilized man." Lin Tian Chongyun Xiaotian raised his thumb and laughed: "The magma flow is a kind of ground fire, and there is underground coal burning, all kinds of combustible underground Sexual gas burning, etc., these things release huge energy. Through the surface cracks, the energy is released, which is ground fire. "

"Just, I don't know, what kind of ground fire is under the sword furnace?" Lin Tian looked at Tang Banqing.

"My old lady is not a geological expert. Where do I know what it is? It is said by the ancients that it is ground fire, just like those mysterious sea eyes, can you explain it? But you said very well Makes sense, maybe we are standing on an invisible volcano. "Tang Banqing glanced at a few people and scared.

Yun Xiaotian and the ghost really glanced around. If it was standing on a volcano, it would be impossible to have a volcano in his heart. A volcanic eruption cannot be resisted by congenital experts.

To man, nature is god, and natural phenomena such as volcanoes, hurricanes, tsunamis, and earthquakes are its magical powers. Any ancient warrior is so small in front of it, not to mention ordinary people.

Lin Tian doesn't matter, because he knows that even if there is a volcano hidden under the ground, it is a stable volcano, because it has not erupted for thousands of years.

He was thinking of other questions, and couldn't help asking: "Donald, as far as I know, even the magma itself has a temperature of more than a thousand degrees, and some materials cannot be melted at this temperature." Thousands of degrees, modern equipment can easily do it. "

"It is said that the highest temperature created by humans is 510 million degrees Celsius and was created by a laboratory fusion reactor device. This temperature is 30 times the temperature of the center of the sun. Even China's artificial solar fusion reactors also have Can create a high temperature of 55 million degrees Celsius, a sword furnace of more than 1,000 degrees, how to smelt some special materials? "

Lin Tian's question is not without reason. If the materials cannot be melted, how to cast a sword? Such as the deformed stone, such as the Qingshuangge meteorite heart.

"Brother, aren't you bragging. How can it be made with a high temperature of 510 million degrees Celsius, which is thirty times the temperature of the center of the sun? What on earth can withstand this temperature?" The ghost was full of disbelief.

Lin Tian scorned: "Brother, it's okay to watch less action movies and more books. There is something in this world called a magnetic field fusion device."

"Well, talking to you educated people is tiring." Tang Banqing shook his head helplessly and said, "If the sword can be cast into a peerless artifact by relying only on the temperature, what is the sword master doing? The most obvious example The bronze sword cast by the Qin Dynasty has high skill, and now it is impossible to pòjiě its craftsmanship and formula. Can this be solved by temperature? "

Lin Tian knew that Tang Banqing was right. Archaeologists unearthed a group of bronze swords from the terracotta warriors and horses pits of Qin Shihuang. These swords had bright blades with a total of eight edges. The error of each edge was less than one wire, and the blade was sharp. , Fine graining, no interlacing texture.

There is also a bronze sword, which was bent by a pottery figurine of more than one hundred kilograms. After being pressed for more than two thousand years, the degree of bending was over forty-five degrees. When the archeologists removed the pottery figurine, the bronze sword rebounded instantly. Straight and natural recovery.

"The boy has been taught." Lin Tiancheng said sincerely, not only because of the knowledge on the sword, but also on the refining of medicine.

Whether it is refining or casting a sword, it is inseparable from fire. A key role of fire is to provide temperature. Sometimes, not the higher the fire, the better the refining, but the precise control of the fire. This is his Comprehend.

"However, you are right." Tang Banqing added a sentence later, saying: "The material is not melted, and it is indeed impossible to cast a sword. However, in addition to the method of increasing the temperature, other materials can be added to promote the melting It melts at lower temperatures. In modern industrial parlance, these substances are called catalysts. "

"A good catalyst should not affect the properties of the material. The best catalyst can even strengthen the material. Qingshuangge's meteorite heart has been unable to melt. One of the reasons is the lack of a best catalyst. I want to find a best catalyst. To the extreme of the characteristics of the meteorite heart. "Tang Banqing said earnestly ~ lightnovelpub.net ~ Lin Tian's heart moved and smiled:" I understand, Tang always thinks that my stone is most likely to be The best catalyst for the heart of the meteorite? "

"Yes, I have an intuition in my heart. For a long time, the best catalyst I've been searching for is it! I need to heat it to determine its attributes." Tang Banqing cast his eyes on the sword furnace, his eyes let out the excitement, and did not hide Your own excitement and joy.

Several people talked this time, the surrounding temperature had risen higher, at least nearly ten degrees higher than the outside, at this time you can also see that the sword furnace Longkou faintly transmitted red light.

Tang Banqing took another shot on the sword furnace, and an observation port was opened at a height of more than one meter. From the observation port, it was more obvious that the red light in the sword furnace had already shone. At the same time, the observation port can just see the deformed stone in the sword furnace.

Although the temperature of the sword furnace was high, both the ghost and Yun Xiaotian couldn't help curiosity, moved forward, approached the sword furnace, and looked curiously at the deformed stone in the firelight. The temperature of the sword furnace continued to rise, but the people present seemed to have forgotten the sweltering heat in the underground space, staring at the deformed stone, especially Tang Banqing, his eyes blinking.

"Ah ..." Yun Xiaotian exclaimed, shouting at the deformed stone: "Look, it's melting!"

Hearing Yun Xiaotian's shout, Lin Tian's mouth showed a smile, not because of his excitement, but because ...

Lin Tian turned his eyes and looked at Tang Banqing. Tang Banqing was not affected by Yun Xiaotian's cry at all, nor was he out of shape because of the deformation of the stone.

She frowned at the deformed stone for a while, then suddenly said, "No, it's not melting!"
