Chapter 1909 You can really have such a way, Na Lu is willing to admit defeat directly
Everyone present saw the weird smile on Lu Dongzan's face who couldn't find a way.
"His Majesty, Emperor Tang, I really have no way of identifying the authenticity of these two golden lions. However, this does not mean that Lu has lost."
Hearing this, Li Shimin raised his eyebrows and couldn't help but asked with some doubts.
"Why is this?"
"Because in all previous competitions, I and Xiao Cheng Taibao competed together."
"But this time, although Xiao Cheng Taibao had a problem, he did not dare to leave the competition."
"That proves that there is nothing he can do." After saying this, Lu Dongzan raised his finger and pointed it like a sword, directly at Cheng Sanlang who was standing not far away.
Li Shimin stroked his long beard and had to admit that the Tubo Prime Minister Lu Dongzan was also a very smart man.
"...Interesting, Cheng Sanlang, do you have any idea?"
"Of course I do." Cheng Chubi saluted Li Shimin, then turned his head and said sincerely to Na Lu Dongzan.
"Some people don't have the ability to solve such small problems by themselves, and that's their own problem.
It doesn't mean that Mr. Cheng is as incompetent as that person, okay?"
"!!!" Although Cheng Sanlang only said this to Lu Dongzan, everyone in the hall turned pale.
They all felt targeted by this bastard Cheng Sanlang, and the same was true of His Majesty the Emperor of the Tang Dynasty who was standing behind the imperial case.
Suddenly his breathing became heavy, and sparks almost came out of his nostrils. His eyes were almost burning as he stared at the proud Cheng Sanlang.
You bastard, just wait, don't let me catch you, I don't think you want any salary in this life.
He and Cheng Sanlang didn't deal with each other at first, but just now Cheng Sanlang used tricks to try to win peace in his tea bowl.
Chu Suiliang, who had no tea to drink, couldn't help but said sadly.
"Cheng Sanlang, do you mean that you have a way to identify the authenticity of these two hollow golden lions without destroying them?"
"That's natural." Cheng Chubi glanced sideways at that old guy Chu Suiliang. What the hell, do you want to help the Tubo people?
Lu Dongzan took a deep breath, showed a determined smile, and said to Cheng Sanlang.
"Oh, since you, Little Cheng Taibao, are so capable, it would be better if you, Little Cheng Taibao, also use a stick of incense.
Use a method that can convince everyone present to find out the difference between these two golden lions."
"You really have such a way, Na Lu is willing to admit defeat directly, surrender to the Tang Dynasty on behalf of Tubo, and no longer compete with Xiao Cheng Taibao for the prince's consort on my lord's behalf."
"If you, Little Cheng Taibao, clearly say that you have a solution, but you don't have the convincing ability, then you will lose this round."
After hearing this, Qin Ling and Na Sang Buza's expressions suddenly changed, but soon, they also realized.
Cheng Sanlang has already won three battles in a row. If he wins this battle again, it will be equivalent to winning the first four battles.
Even if Lu Dongzan wins the next two battles, there is no point in it at all. It is better to go for this one directly.
#####
Hearing this, Cheng Chubi immediately became happy and turned his head to look at Lu Dongzan.
"you sure?"
Lu Dongzan glanced at all the people present and spoke loudly.
"Your Majesty, the Emperor of the Tang Dynasty, as well as you, the civil and military officials of the Tang Dynasty and the Manchu Dynasty, as well as the envoys of the Tibetan countries, testify that Mr. Lu will never break his promise and get rich."
Li Mingda and Wu Meiniang both saw Cheng Sanlang with his hands behind his back, standing tall and smiling calmly without fear.
"Forget it, since Ambassador Lu even said such words, Cheng will naturally want to convince you."
"Okay! In that case, come and light the incense." Li Shimin ordered without any nonsense.
The wise and powerful Emperor of the Tang Dynasty also wanted to see what kind of methods he, Cheng Sanlang, could use.
Distinguish the difference without destroying the two golden lions of the sky.
Cheng Chubi bowed confidently to the Emperor of the Tang Dynasty.
"Your Majesty, please ask someone to find a copper basin, a bowl large enough to completely place this golden lion, and a large pot of water."
"..." Li Shimin looked at Cheng Sanlang in confusion. I asked you to find the difference between the two sky lions. What do you want to do?
The same question popped up in everyone's mind. If those things have yarn, you guys are trying to mess around, right?
Although Li Shimin was full of doubts, he still sent the eunuch to get it.
In a short time, the eunuch fetched a copper basin, a large porcelain bowl, and a large pot of water.
Li Shimin had already walked to the table where the case was received and watched Cheng Sanlang place the bowl in the copper basin.
Then he began to pour water into the bowl carefully, as if he was afraid of spilling the water, until the porcelain bowl was completely filled with water.
Only then did Cheng Sanlang give up. Then Cheng Sanlang picked up an empty golden lion and carefully put it into the porcelain bowl filled with water.
As the golden lion slowly entered the water, the water, which was already full and was about to overflow, naturally began to flow along the edge of the bowl into the copper basin.
After the golden lion in the sky was completely submerged in the water, Cheng Sanlang asked Li Ke to hand over a hard object, and drew a horizontal line along the water surface of the copper basin and on the inner edge of the copper basin.
Then he took out the golden lion and put it aside, poured out all the water in the copper basin, and asked the eunuch to bring a towel to dry it.
He put the bowl inside again, filled it with water again, then picked up another gold-threaded empty lion and slowly immersed it into the water bowl.
Everyone stared with wide eyes, watching the overflowing water slowly rising, approaching the horizontal line little by little.
At the end, the water surface actually crossed the horizontal line and was still rising.
Then, I heard Cheng Sanlang's very determined and confident voice ringing in my ears.
"This second lion is made of lead, but the first lion is made of pure gold."
"How do you know?" Li Shimin, the Emperor of the Tang Dynasty, couldn't help but curiously asked the question first.
"If your Majesty doesn't believe it, you only need to smelt this golden lion to find out."
"No, no, that's not my question. What I want to ask is, can you tell the difference just by the height of the water surface?"
When Cheng Chubi heard this, he looked at the pair of eyes full of curiosity and laughed, and explained as if he were the president of the Cheng University of the Tang Dynasty.
"Of course, because gold and lead have different densities, there will be a difference in the amount of water spilled from a pure gold lion of the same weight and a non-pure gold lion mixed with lead."
"This is based on a relatively simple mechanical principle in physics, also known as Archimedes' principle."
