Tang San naturally didn't know that Xiao Wu was thinking wildly because of his strange actions, and carefully took out the human-head-sized crystal from the Twenty-Four Bridges Moonlit Night, placing it on the bed. He gently stroked the uneven surface of the crystal, as if caressing a treasured treasure.

  Xiao Wu knew that Tang San was not a rash person, and since he attached such importance to this crystal, there must be some secret contained within it. She squatted down beside him, waiting for his explanation.

  "Not all crystals are as precious as amethysts." Tang San finally said after a long while.

  "What kind of crystal is precious?"

  Tang San solemnly said: "It's a Crystal."

  "What's a Fa Jing?" Little Dance looked at him in surprise, she hadn't even heard of this term before.

  It's no wonder Xiao Wu didn't know, this concept originally didn't belong to this world. It was brought by Tang San from the Clear Sky School.

  At the time of Tangmen, apart from being in charge of making mechanical soul rings for Anqi, Tang San also used to help inner door disciples cast various hidden weapons. He was extremely clear about the research on materials for hidden weapons and all kinds of precious materials.

  "What is known as 'faux crystal' refers to the phenomenon where some natural crystals, under certain conditions, are influenced by external factors and produce golden thread-like objects within the crystal. This golden thread is also called 'crystal hair' or 'golden hair', just like human hair. Regardless of the color of the crystal, if a single crystal hair appears, its value exceeds that of the best natural crystals of any color. Crystals with crystal hair are called 'faux crystals'."

  Xiao Wu said, "You're not telling me that this big crystal is the Crystal Ball, are you? I didn't see any golden threads, and besides, I've never heard anyone mention a Crystal Ball before. Even if it were one, if nobody recognizes it, then it's useless. The two hundred gold coins you spent on it weren't worth it."

  Tang San smiled and said, "No, this isn't a piece of Crystal Hair, but rather a piece of Plank Crystal, the top-grade item among Crystal Hairs."

  Xiao Wu curiously asked: "What is a board crystal?"

  Tang San explained patiently: "The golden threads in the crystal are usually disordered and scarce. However, some crystals that have existed for a very long time may have an increased number of golden threads. When the number of golden threads reaches a certain level and gathers together within the crystal to form a plate-like shape, such a crystal is called a slab crystal. Because it has a large number of golden threads inside and they are extremely regular, the slab crystal is considered the best among all crystals."

  "This crystal appears to be dull on the surface, but upon closer inspection, a golden glow can be seen. The gold plate inside is hidden by impurities on the surface of the crystal, but I am almost certain that it contains at least tens of thousands of strands of golden hair. This is a miracle that could only occur in a crystal that has existed for over 100,000 years. Let alone 200 Golden Soul Coins, even if I had 20,000 Golden Soul Coins, it would still be worth it. I want it not to resell and make a profit, but because it holds special significance."

  Tang San didn't directly say what this special significance was, but instead took out his own cast hammer from the Twenty-Four Bridges Moonlit Night.

  His casting hammer was two sizes larger than the ordinary blacksmith's, and after using this large-sized casting hammer for the first time at the Stone Three Blacksmith Shop, Tang San never changed it again.

  "Xiao Wu, get out of the way." Tang San shouted in a low voice.

  Xiao Wu stepped aside. Tang San placed the crystal plate on the ground, and a faint white light slowly flowed out from his hands into the forging hammer. His face had become extremely solemn, and in an instant, he had raised his internal energy to its limit with the Xuan Tian Godly Power.

  "Xiao San, what's going on..." Xiao Wu looked at him in shock, she had already sensed what Tang San was about to do, but couldn't understand why he wanted to do it.

  His calf suddenly exerted force, his body half-turned, and the first strike of the Wind Chasing Hammer Method was suddenly swung out, infused with all of Tang San's internal energy. The hammer head shone brightly with white light, and a series of explosive booms echoed through the air. The massive hammer head heavily smashed towards that piece of crystal plate.

  Xiao Wu subconsciously covered her own ears.

  Bang——, in the midst of the deafening crash, the entire Rose Hotel shook violently. A crisp cracking sound rang out under the iron hammer, and in Tang San's full-force strike, that piece of crystal was instantly smashed into powder.

  But at the same time as the slab crystallized into powder, a strange scene appeared, countless golden light spots burst out from the slab crystal, and scattered in this bedroom with a peach heart bed. As if the entire room was covered with a layer of golden misty light.

  Xiao Wu was startled, and hurriedly urged her own soul power to block the golden light dots outside. Fortunately, those golden lights' penetrating force were not strong, and did not bring any harm to her.

  The dazzling golden light gives people a dizzy and bewildering feeling, the crisp and pleasant sound of ding-dong, some colliding on the wall, some colliding on the door and window, and some directly falling on that peach heart-shaped bed, the entire bedroom is completely covered by a layer of golden light.

  The crystal shattered into a mess of powder, but as the golden light in the air slowly descended, Xiaowu discovered that the floor and bed in the room had an extra layer of golden glitter. Or rather, a layer of golden particles.

  Each golden grain was extremely uniform in size, about the same as a grain of rice, plump and round, with a faint golden light flashing on it. Xiaowu subconsciously picked up one and pinched it in her hand, finding that this golden grain was slightly soft but very elastic, and even with her soul power, she couldn't pinch it flat.

  "Brother, these can't be pure gold, right? Even if they were, they wouldn't be worth more than your 200 Gold Soul Coins."

  Tang San was extremely excited, truly extremely excited. Since coming to this world, his emotions had never been in such a state of high excitement before, even more so than when he first obtained the first soul ring and broke through the bottleneck with the Mysterious Heaven Technique.
