Zombie Bodyguard-Chapter 1437 - 1434: Supreme Catalyst

Lin Tian looked at the Sword Furnace, his gaze seemingly penetrating the base, and the sword forging methods narrated by the female zombie flashed through his mind, unavoidably speaking out loud: "Heavenly thunder, Earth fire..."

Ghost blinked, looked at Lin Tian, and said strangely: "Brother Tian, are you talking about a male and female coming together, sparking, and then something unsuitable for children or indescribable happens, that’s called heavenly thunder striking earth fire."

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

"Haha, this young man isn’t wrong either. The male is Qian, the sky, the female is Kun, the Earth, the harmony of heaven and earth, the union of male and female, that’s heavenly thunder and earth fire." Tang Banqing laughed twice, saying very seriously.

Lin Tian and the others’ faces were filled with black lines, this old woman spoke too directly.

"Earth fire is actually underground magma flow, right?" Yun Xiaotian interjected.

"Ah, you hit the nail on the head, Xiaotian is indeed a civilized person." Lin Tian gave Yun Xiaotian a thumbs up and laughed, "The magma flow is a kind of earth fire, and also underground coal combustion, underground combustible gases burning, etc., these things release massive energy, through the earth’s crevices, energy is released, which is earth fire."

"But, I wonder what kind of earth fire is under the Sword Furnace?" Lin Tian looked toward Tang Banqing.

"I’m an old woman, not a geological expert, how do I know what earth fire it is, the ancients said it is earth fire, so it’s earth fire, just like those mysterious sea eyes, can you explain them clearly? However, you make a good point, maybe we’re standing on an invisible volcano." Tang Banqing glanced at the few people, trying to scare them.

Yun Xiaotian and Ghost indeed looked around, if they’re standing on a volcano, it’s impossible not to feel uneasy, volcanic eruptions are something even Innate Experts can’t withstand.

To humans, nature is god, and phenomena like volcanoes, hurricanes, tsunamis, earthquakes are its Divine Skills, any Ancient Martial Artist is so small in front of it, let alone ordinary people.

Lin Tian, however, was indifferent because he knew, even if there is a hidden volcano underground, it’s a stable one because it hasn’t erupted for hundreds of years.

He was thinking about other problems in his mind and couldn’t help but ask: "Old Tang, as far as I know, the temperature of even magma itself is only in the thousands of degrees, at this temperature some materials can’t be melted. A temperature in the thousands is easily achievable with modern equipment."

"It’s said that the highest temperature created by humans is 510 million degrees Celsius, created by a laboratory’s nuclear fusion reactor, which is thirty times the temperature of the sun’s core. Even the artificial sun nuclear fusion reactor of our country can create temperatures as high as 55 million degrees Celsius, how can a Sword Furnace at a thousand degrees melt some special materials?"

Lin Tian’s doubt was not unfounded, if materials can’t be melted, how to forge a sword? For example the transformation stone, for instance, that meteorite heart of Qingshuang Pavilion.

"Brother Tian, aren’t you boasting? 510 million degrees Celsius, thirty times the temperature of the sun’s core, how is that possible to create? What on Earth can withstand that temperature?" Ghost was full of disbelief.

Lin Tian despised: "Big brother, watch fewer action movies when you’re free, read more books, this world has something called a magnetic field nuclear fusion device."

"Sigh, it’s tiring talking to you cultured people," Tang Banqing shook his head helplessly, saying "If forging swords was as simple as just relying on temperature, then what’s the point of a Swordsmith? The most obvious example is the bronze sword forged in the Qin Dynasty, its craftsmanship is so exquisite that modern times still can’t crack its technique and formula, is this something temperature can solve?"

Lin Tian knew Tang Banqing was right, archaeologists unearthed a batch of bronze swords from Qin Shi Huang’s Terracotta Army Pit, these swords, with shiny blades and a total of eight facets, each facet with a deviation less than a single strand of hair, sharp edges, meticulous grind patterns, and flawless texture.

There was even a bronze sword bent by a hundred kilogram clay figurine, pressed for over two thousand years, bent over forty-five degrees, but when archaeologists removed the figurine, the bronze sword instantly snapped back straight, naturally restored.

"This kid has learned something." Lin Tian sincerely said, not just because he gained insights on sword forging, but also received many inspirations in medicine refining.

Whether it’s medicine refining or sword forging, fire is indispensible, a key role of fire is to provide temperature, sometimes, it’s not always true that higher level fire is better for medicine refining, rather it’s about precise control of fire, that’s his understanding.

"However, you got one thing right," Tang Banqing added, saying: "Materials not melting indeed can’t forge a sword, however, besides increasing temperature there’s another way to melt materials, which is to add other substances to make them melt at lower temperatures. In modern industrial terms, these substances are called catalysts."

"Good catalysts shouldn’t affect the properties of materials, excellent catalysts can even strengthen materials, Qingshuang Pavilion’s meteorite heart couldn’t be melted because it lacks excellent catalysts. I’m looking for an excellent catalyst to bring out the ultimate properties of the meteorite heart." Tang Banqing said earnestly.

Lin Tian’s heart moved, he couldn’t help but laugh: "I understand, Old Tang thinks my stone might be an excellent catalyst for the meteorite heart?"

"That’s right, I have a gut feeling that the excellent catalyst I’ve been searching for so desperately is it! I need to heat it, determine its properties." Tang Banqing gazed at the Sword Furnace, eyes glowing with excitement, not concealing her thrill and joy.

While the few people were talking, the surrounding temperature had already increased even higher, at least nearly ten degrees higher than outside, at this point it could also be seen that the dragon mouth of the Sword Furnace faintly emitted a red glow.

Tang Banqing patted the Sword Furnace again, an observation port opened at a height of over a meter on the furnace body, through the observation port it was more apparent that the inside of the furnace was already glowing red. At the same time, the observation port was just right to see the transformation stone inside the furnace.

Although the temperature of the Sword Furnace was high, Ghost and Yun Xiaotian were unable to resist their curiosity, instead of retreating, they moved closer to and looked curiously at the transformation stone amidst the firelight. The temperature of the Sword Furnace continued to rise, but those present seemed to forget the stuffy underground space’s heat, their eyes fixed firmly on the transformation stone, especially Tang Banqing, not blinking an eye.

"Ah..." Yun Xiaotian screamed, pointing at the transformation stone and shouted: "Look quickly, it’s melting!"

Hearing Yun Xiaotian shout, Lin Tian’s mouth revealed a slight smile, not because of his excitement, but because...

Lin Tian turned his gaze toward Tang Banqing, who was not affected by Yun Xiaotian’s shout and did not lose composure due to the transformation stone’s change. 𝗳𝐫𝚎𝗲𝚠𝚎𝗯𝕟𝐨𝘃𝚎𝗹.𝗰𝗼𝗺

She frowned at the transformation stone for a while and suddenly said, "No, it’s not melting!"
