Chapter 646: The large vat is fake, the psychological tactic is real, the way of solving a case

He held the black pot from Lady Lin's hands and faced the hundred officials and Wu Zhao.

He said slowly, "The strangeness of this case lies in the talk of a wandering soul!"

"No one in the world can say that a wandering soul entrusting a dream is ridiculous, and no one can say it is true!"

"The key point of Lady Lin's accusation against the Qin Wenchang couple is the wandering soul entrusting a dream, claiming that a treacherous person made him into a black pot."

"Because of this point, Lady Lin searched every shop in Changancheng selling black pots, picked this one at a glance, and even her nightmares decreased, leading her to believe this was the black pot of her husband, Lu Wenzheng!"

"Therefore, she found the Qin Wenchang couple and the woodcutter through the shopkeeper of the Six Directions Pavilion."

"Thus, the nightmare is the root, and the black pot in Lady Lin's hands is the root."

"So, as long as we can prove that the black pot Lady Lin picked at a glance was made from Lu Wenzheng's remains, we can prove the talk of the wandering soul; conversely, if the black pot was not made from Lu Wenzheng's remains, it means Lady Lin is lying!"

"As long as we clarify this point, the case will come to light."

As soon as these words were spoken, Lu Wen sneered, "Lord Gao, which of these things you said does the entire court not know?"

"But the root of the problem is how to prove that this was made from Lu Wenzheng's human bones?"

"Could it be that someone should go to the underworld and ask Lu Wenzheng himself?"

"I thought Lord Gao had some amazing method; it turns out to be a pile of nonsense!"

Lu Wen shook his head, his face full of mockery.

Wang Zhong and Xu Xuanji also shook their heads secretly.

But Gao Yang's expression was calm, "The dead cannot speak, but the dead can also speak."

"The answer lies in these two large vats filled with water!"

"They can prove all of this!"

As soon as these words were spoken, everyone's gaze turned to the large water vats in the center of the Jin Luandian.

"Water vats, proving the talk of a wandering soul?"

Everyone's complexion changed, somewhat shocked.

Wu Zhao felt a surge of curiosity and asked, "Gao Yang, how does this prove it?"

"Your Majesty, speaking of this, I must mention Archimedes' principle."

"Archimedes' principle?"

Wu Zhao and the hundred officials were all confused.

"Archimedes' principle, simply put, is that there is a mysterious force in water called buoyancy; if an object is submerged in water, the magnitude of this buoyancy is equal to the weight of the water displaced by the object."

"This is a very important theorem for all things in the world."

Wu Zhao took a deep breath and said: "Make it simpler."

"Buoyancy is related to density; the weight of a black pot made of earth pottery is fixed, but if a large amount of human bone is mixed into the earth pottery, the density changes."

"In other words, when the volume is the same, a black pot mixed with human bone will be heavier, and the displaced water will change significantly."

Gao Yang walked toward the two large water vats, then took a silver ingot from his bosom, and said to Wang Zhong.

"Old General Wang, do you have a gold ingot that you can let this official use to verify this in court?"

Wang Zhong widened his eyes and covered his chest, "How did you know I have a gold ingot?"

"Just a guess; Old General Wang, bring it quickly, do not waste time."

Gao Yang reached out his hand to Wang Zhong.

Wang Zhong glanced at Wu Zhao but still took out a gold ingot from his clothes.

Gao Yang took the gold ingot, then held the gold ingot and the silver ingot separately, and threw them into the two large vats.

Almost instantly, with a splash, both the gold ingot and the silver ingot were submerged in the water.

The water that had originally filled the vats overflowed, and clearly, more water overflowed from the vat with the silver ingot.

This scene shocked the hundred officials.

Lu Wen widened his eyes and pulled out a few hairs from his chin.

Gao Yang explained, "Specifically, the density of gold and silver is far greater than the density of water; the weight of the gold ingot is large, and the buoyancy is also large. Because the density of gold is high enough, less water needs to be displaced to achieve its own buoyancy."

"Of course, explaining this clearly is complicated; you all just need to know that because the density of objects is different, they are divided into those with density greater than water, less than water, and about the same as water."

"But the principle is the same; this black pot is mixed with human bone, which leads to a difference in density, and this can solve the case."

The voice fell.

The hundred officials were all confused.

But Lu Zhen reacted, "Kid, that's not right; since the density of objects is different, how did you know?"

"Not to mention gold and silver, how did you know the density of earth pottery and human bone?"

Gao Yang smiled and said, "This official liked earth pottery when I was a child, so I understand it deeply." ===== CHAPTER 648 =====
