Back to the rental house, there was already a thunderstorm outside. A group of people gathered around the living room, waiting for Zhang Xiaowen's explanation.
Zhang Xiaowen pointed to the lightning outside the window and said: "I remember seeing it there before. It is said that under certain circumstances, thunder and lightning can record what is happening at the moment like a video recorder. By chance, it will be like a movie. Release the things I recorded before, I think I encountered this phenomenon today."
"If you are like this, then how can you infer that the person who jumped into the well in the picture is the Dragon King that the uncle in the day said?" asked Fatty Chen.
"I inferred based on their clothes and what the uncle said. Uncle said that the reason why he saw the dragon king jumping into the well was because of thunder that night, and he got up to collect his clothes. That is to say, it happened to be a thunderstorm day. The special conditions for the video. And I saw one of them wearing a yellow military uniform, which coincided with the situation of that era! Plus, I heard the conversation between the two!"
Zhang Xiaowen's words aroused everyone's interest. Gao Zihan hurriedly asked: "What did they say?" Zhang Xiaowen recalled explaining the general meaning of the dialogue between the two to everyone, and then said his own analysis.
"First of all, they must have entered the underground palace before. The maze inside should be very complicated, so they will be prepared for the second time. Secondly, they mentioned two ancestors in the dialogue. If I remember correctly, Shi Yuejin I once said that because two people in their family secretly searched for the entrance of the underground palace and disappeared, they explicitly forbid the people to search for the entrance of the underground palace privately. Therefore, these two people should be Shi Yuejin's tribe. According to my previous inference, one of them should be Shi Yuejin's father. This can also explain why Shi Yuejin’s father insisted that Shi Yuejin stay to guard the underground palace, because he knew very well that this underground palace really existed, and there might be something terrible in it!"
Niu Yijun nodded: "Zhang Xiaowen did infer that the Jinyiwei guards might have stolen himself. According to the pictures he saw, this inference should be completely correct. Then just try to find the entrance to the underground palace."
"Well, the next step is to solve the problem of counterweight, first dive to a depth of 10 meters
, And then figure out the meaning of the crowing of the copper chicken, and all the problems are solved! "Chen Fat said.
"I think about it, but I still think that the crow of the bronze chicken refers to the light! First of all, it is to eliminate the time. The bronze chicken should be similar to the current clock, so its crow time must be fixed! If the entrance of the underground palace is fixed It’s too easy for people to discover when the time is opened. So it’s definitely not time. The second is to eliminate vibration. The crow of a bronze chicken will cause vibration, but if the entrance of the underground palace is opened by vibration, it will be caused by the bronze chicken. The vibration is too weak. Maybe the vibration caused by the passing carriage will be larger than it, so it can basically be eliminated. In this way, only light is left. It may be a certain time in the morning when the copper chicken crows, and then through the light Refraction, it may just hit the organ at the entrance of the underground palace!" Zhang Xiaowen expressed his opinion.
Niu Yijun nodded: "I think so too. If it is light, then we can try to imitate that kind of light, or just give up the light and look for it directly. Anyway, the well is that big and it will always be illuminated!"
Zhang Xiaowen affirmed: "Okay! No matter what, let's check again tomorrow. I believe the two Jinyiwei can find the entrance at night, so can we!"
After discussing the next step, everyone who had been tired for a day went back to their rooms to rest, recharge their energy and prepare to go down the well the next day.
Late at night the next day, the group came to the well again. This time Zhang Xiaowen tied sandbags on his body, and then slowly went down the well again.
This time the speed of the dive was indeed much faster than last time. After Chen Pang confirmed that the rope had reached 10 meters, he gave Niu Yijun an "OK" gesture. Niu Yijun nodded, then poked his head and looked down. The rope dangled straight into the water along the wall of the well. This time Zhang Xiaowen should have reached the position of about 3 feet.
Zhang Xiaowen carefully searched every inch of the well wall, and suddenly he found that a well wall was very smooth, with no algae growing at all. Zhang Xiaowen was overjoyed, there must be a demon if something goes wrong, it seems that this stone wall is probably a mechanism. Zhang Xiaowen fumbled along the stone wall for a long time and still had no gain at all, so he had no choice but to return to the surface to take a breath.
After getting better, Zhang Xiaowen started to dive again, just off
When I dropped a little, I heard a "boom" from the surface of the water. Zhang Xiaowen hurriedly looked up. I don't know where the cauliflower snake jumped into the water.
Zhang Xiaowen knew that the snakes in his hometown were not poisonous, and the snake didn't mean to attack him. After swimming twice in the water, he climbed up against the well wall. Zhang Xiaowen breathed a sigh of relief and thought: I'm so timid, the sound of a snake entering the water made myself jump! But having said that, the sound of the snake entering the water was loud enough.
Thinking of this, Zhang Xiaowen's mind suddenly came to light: By the way, it's the voice! Sound waves travel faster in the water than in the air, so the sound of the snake entering the water feels louder than usual. And the most important function of the crowing of the copper chicken is the sound, which I actually ignored! If the mechanism at the entrance of the underground palace is voice-activated, then since people cannot make sounds in the water, you must bring a copper chicken to open the mechanism! But with the development of science and technology, you don't need a copper chicken to make a sound in the water, and the two people in Brother Shi's father and son's generation did not use the copper chicken, so they should be the mechanism opened by other sounds.
Thinking of this, Zhang Xiaowen was overjoyed and pulled the rope twice. The people on the well platform received Zhang Xiaowen's signal and pulled Zhang Xiaowen up without hesitation.
As soon as he came up, Zhang Xiaowen said to everyone excitedly: "I think I guessed the meaning of the crowing of a copper chicken! It's sound. The speed of sound in the water is different from the speed in the air, so it can be done. To avoid the possibility of opening the palace gate by other sounds, this is why it is necessary to set the palace gate at a position of 3 feet below the mine, because it must be submerged by the underground river!"
Seeing Zhang Xiaowen with excitement on his face, the rest of the people had no bottom. Zhao Dali wiped the sweat from his forehead: "You mean, this palace gate is voice-activated?"
Gao Zihan "cut" and said, "What's all the fuss about, the ancients' skill is so ingenious, maybe they have already researched voice control!"
Niu Yijun pursed his lips: "It's also possible, anyway, we don't have a good idea, so we might as well give it a try!"
Zhang Xiaowen nodded excitedly: "Take a waterproof bag and use my mobile phone to download a rooster crowing sound, I will go down and try!"
