The wood was lying on the body of the ancient building, suffering from the torture of nature as it became mottled day by day. Thunder and lightning were the most unwilling to be lonely. They would jump from the clouds and bite the body of the wood again and again. Therefore, the ancient craftsmen used their wisdom to launch a game in exchange for the survival of the residence under the thunder and fire.
On the bank of the vast Dongting Lake, there stood a 39-meter-high octagonal seven-story brick tower. It looked particularly tall and straight. The brick tower was octagonal and pointed at the top. In the middle, there was a dark iron pestle pointing to the sky. The decorations around were structured according to the structure, showing the appearance of an octagonal sandwich. A few iron chains connected to the top and fixed the structure climbed along the ridge to the wing corners, winding down and finally converting to the earth in a crawling posture. It was the Ci Shi Tower, and also the earliest evidence of the confrontation between the wisdom of the ancestors of this ancient civilization and the thunder and fire. It was the combination of the iron pestle and the iron chains that enabled the ancient tower to escape from the thunder and fire countless times.
The lightning rod was not a product of modern society. As early as more than a thousand years ago, it appeared in the Central Plains! In the Roasted Scorch, there was such a record: In the Han Dynasty, Bai Liang Hall was in a fire. A wizard suggested that a fish-tail-shaped copper tile should be placed on the roof to prevent the fire caused by thunder and lightning. The fish-tail-shaped tile on the roof was actually used as a lightning rod. It could be regarded as the prototype of the lightning rod.
In ancient times, when the gods embraced each other, simple technology could only take root and sprout in the doubts of the ancestors by "turning around" the mountains around religion. Therefore, the ancestors' avoidance of thunder and lightning followed the civilization of that era and were herded in the river valley waiting for awakening.
In the traditional culture of China, metaphysics was quite representative, such as the five elements and the eight trigrams. In the field of the Eight Trigrams, the "Zhen" hexagram represented "Thunder". After combining the positions, there were also "South Li, North Kan, East Zhen, West Dui," as well as "South Sparrow, North Black Tortoise (Turtle Snake), East Azure Dragon, West White Tiger."
Therefore, under the "presumption" of the magicians, the ancients unanimously formed the thought that "thunder followed the dragon". From then on, in order to prevent buildings from being struck by lightning, the forebears had to construct and install lightning protection facilities, which were known as "Dragon Suppression".
Therefore, in the extraordinary appearance of the ancient buildings, many lightning arresters known as "Dragon Guards" began to grow and multiply on the bodies of the ancient buildings in China.
For example, in China, the tip of some ancient towers was often coated with a layer of metal membrane. Then, it was connected to the central pillar of the underground tower using a material that was easy to conduct electricity. The end of the pillar was connected to the "Dragon Cave" where the metal was stored. This formed a kind of ancient "dragon subduing".
In addition, such as the "owl tails" that stood upright on many ancient towers and palaces, the animal-shaped tiles on the roofs, and the so-called "Thunder God Pillars" that often stood in the tall temples, they all formed good conductive channels with the earth and became important members of the "dragon suppressors".
These were the crystallization of the wisdom of China's ancient craftsmen! For thousands of years, our ancestors had used extreme ingenuity to develop the simple science into a shocking appearance. Although it had weathered wind, rain, thunder, and lightning, it had remained unmoved for thousands of years!
And the "dragon subduing" on the roof of the Imperial Ancestral Temple had been modified by someone into a gunpowder magazine. Li Zexuan raised his head and saw several thin iron wires being pulled down from the cracks in the roof and inserted into a wooden box at the top!
Although Li Zexuan didn't graduate with a history major in his previous life, he still knew that ancient buildings had lightning arresters. Besides, even if he didn't know this in his previous life, he still had the memories of his previous life!
Thus, when Li Zexuan saw those iron wires coming down from the cracks in the roof and associated them with the 'Dragon Subduing' on the roof, as well as Li Junxian's secret letter stating that 'the clouds would change color and thunder would rumble', Li Zexuan understood everything!
Someone wanted to attract lightning to the Imperial Ancestral Temple. When the lightning sparks were combined with the sulfur and charcoal in the room, the Imperial Ancestral Temple would most likely be doomed!
But would the sulfur and charcoal really be detonated by the lightning sparks?
Li Zexuan wasn't sure! After all, these two things were flammable at most. Even Li Zexuan didn't know if they could be ignited by the lightning sparks! Because he had never done any experiments in the modern era!
"Mm? The color of the box at the top seems to be different! Is it a coincidence, or are the things inside different? "
At this moment, Li Zexuan noticed that the color of the wooden box at the top was slightly lighter. He couldn't help but feel a little suspicious.
After pondering for a moment, Li Zexuan tapped the ground with the tip of his foot, and his whole body left the ground. He soared into the air and flew toward the box at the top. He saw that the top of the box had been punched with five small holes, which were just enough for five iron wires to pass through!
Li Zexuan pulled out the metal wire from the wooden chest. Then, he carried the wooden chest and returned to the surface. Just as he was about to open the wooden chest to investigate, he heard a series of hurried footsteps coming from outside the Imperial Ancestral Temple. His heart skipped a beat, and he turned around to greet them.
Just as he reached the main hall of the Imperial Ancestral Temple, he saw Li Zexuan striding in. Li Zexuan hurriedly clasped his hands and bowed. "Paying respects to Your Majesty!"
Li Zexuan's face was dark as he said in an unfriendly tone, "Hmph! Marquis Yong 'an, how dare you cause trouble in the Imperial Ancestral Temple! "
Li Zexuan clasped his hands and said seriously, "Your Majesty, this subject did not cause trouble. This subject came to the Imperial Ancestral Temple to investigate a case!"
"Investigate a case?"
Li Zexuan's heart sank when he heard this. Things had indeed reached the worst-case scenario that he had predicted. The Dragon Sect's influence had already infiltrated the palace! Thinking of this, he asked with an ugly expression, "Then what did you find out?"
Li Zexuan was about to speak when he suddenly paused. After a moment of hesitation, he said, "Your Majesty, please dismiss your attendants and follow this subject to a place!"
Since someone like An Dezhong could be used by the Dragon Sect, Li Zexuan was not sure if there were any spies among Li Zexuan's attendants. Therefore, for safety's sake, he suggested that Li Zexuan dismiss his attendants and follow him to the special room in the northwest!
Li Zexuan clearly understood this and did not hesitate. He turned his head and ordered, "All of you wait outside. Today, without my orders, no one is allowed to take half a step into the Imperial Ancestral Temple!"
"Understood!"
The imperial guards and eunuchs who followed Li Zexuan all cupped their fists and answered.
Li Er nodded, then turned to look at Li Zexuan and said indifferently, "Lead the way!"
"Yes! Your Majesty! "
Li Zexuan made a sound of agreement and turned around to lead Li Er towards the first house in the northwest.
After a while, the two of them arrived at the room where the sulfur and charcoal powder were stored. Li Zexuan pointed to the wooden boxes in the room and said to Li Zexuan, "Your Majesty, these boxes were sent from outside the palace by Steward An. They are the location of the Dragon Sect's secret plot!"
"You're saying that the Dragon Sect's secret plot is related to these wooden boxes?"
Li Zexuan's eyes narrowed.
"That's right!"
Li Zexuan nodded and pointed to the five iron wires hanging from the cracks of the roof. "Your Majesty, please take a look. The other end of these five iron wires is connected to the dragon seal on the roof and the other end is connected to one of these wooden boxes! Your Majesty, do you know what is in these wooden boxes? "
Li Er frowned and took the initiative to open a wooden box. Then, he put his hand inside and grabbed a handful of powder. He looked at it carefully. Suddenly, a layer of cold sweat appeared on Li Er's back!
"Is this sulfur powder and bamboo charcoal powder?"
Because of Li Zexuan, Li Zexuan was one of the few people in the world who knew the formula of HY. When he saw the sulfur powder and bamboo charcoal powder, Old Li had the urge to run away. He had seen the power of gunpowder and he did not think that his body could withstand the power of gunpowder!
