Seeing Lin Han's solemn and worried expression, Wang Qiankun couldn't help but raise the corner of his mouth and sneer.

He knew very well why Lin Han looked hesitant because the things inside were carefully selected by him. Not to mention Lin Han, even some experienced treasure appraisers would be stumped if they came.

"Do you know what kind of antiques are most common in this world?"

Wang Qiankun walked towards Lin Han, looking superior and proudly imparting knowledge to Lin Han as he walked.

“It’s not pearls or gemstones, because those things are not produced in large quantities and are not cheap. The most common antiques are the cheapest and most popular ones.

Gold and silver are easy to mine and common, so they are hard currencies in any era.”

"In our thousands of years of history, countless dynasties have had very popular gold and silver products. Although they are not the most common, they are also hard currency. You should be able to feel it without me telling you, right?"

"Copper coins!"

Lin Han frowned and uttered two words with a heavy heart.

In the past, gold would be made into gold ingots, or gold bars.

Although it is common, it was only owned by high-ranking officials in the past.

But silver ingots are different. They are of relatively low value and are in the hands of some wealthy children.

Therefore, compared with gold ingots, silver ingots are larger in quantity and more numerous.

But the largest amount is undoubtedly copper coins, because even ordinary people have them.

Moreover, in history, almost all countries with advanced smelting technology had the habit of making copper coins as circulating currency.

At the same time, the dynasty, emperor and reign title will also be printed on it.

But if it really exists, it would be very easy to identify. Lin Han could determine which dynasty it was from by feeling the words.

However, the words on this thing have been worn away, and if I am not mistaken, this is not the result of wear and tear due to improper storage, but was deliberately worn away by Wang Qiankun.

This was to prevent him from knowing what era the copper coin was from, but Wang Qiankun himself knew very well what era it was from.

This is why Wang Qiankun was so confident. He was sure that Lin Han could not figure out what era the silver ingot was from.

Guess it by luck again? That's hard. Guessing accurately among hundreds of dynasties is as difficult as ascending to heaven.

"Well? Ten minutes have passed. If you still can't come up with an answer, you'll have to give up."

Seeing that Lin Han hadn't answered or given the correct answer, Wang Qiankun became a little impatient.

"Daoguang Tongbao copper coin." Lin Han had no choice but to guess at random and then put his hand back.

At this time it was Wang Qiankun's turn to touch. He was on the opposite side and also reached his hand in. After pretending to touch it for a while, he showed a confident smile.

"Guangxu Tongbao copper coins!"

The two people gave different answers, and before the black cloth was removed, the audience in the stadium didn't know who was right or wrong.

But Lin Han and Wang Qiankun already knew the answer.

The right person must be Wang Qiankun!

Sure enough, after the black cloth was lifted, the copper coin inside had four blurry words "Guangxu Tong Bao" printed on it.

Although it was deliberately smoothed, one can still see that it is the four characters "Guangxu Tong Bao".

"Amazing! You can feel out such flat characters? How did you do it?"

"It feels very difficult, right? You are worthy of being our Golden Autumn Province's treasure appraiser! You are so strong!"

…

Seeing the smoothed-out characters on the copper coin, everyone present understood how difficult it was to tell that it was a Guangxu Tong Bao coin.

They couldn't help but be surprised.

"It looks like you used up all your luck when you tossed the coin just now. I won!"

Wang Qiankun raised the corner of his mouth, looked at Lin Han proudly, and said.

Lin Han nodded slightly. Although he understood that this competition was unfair, there was nothing he could do. With tens of thousands of people watching, he couldn't go back on his word and take the key back in public.

Wang Qiankun was too lazy to pay attention to Lin Han at this time. He raised his right hand and waved to the tens of thousands of people in the stadium. He took the microphone handed over by the host with his left hand and said loudly:

"Today's game was very thrilling. In fact, I only guessed it with a little luck. I originally had many answers, but luckily the goddess of luck was on my side. So I declare that the winner of today's game is me, Wang Qiankun!"

"Oh~ Wang Qiankun! Wang Qiankun!"

"Wang Qiankun! Wang Qiankun!"

…

The people in the gymnasium were in an uproar, shouting Wang Qiankun's name.

Lin Han and the others have already walked off the stage and are ready to leave. Now that all six keys belong to Wang Qiankun, there is no point in them staying here any longer.

Unless they can steal the six keys, there are security guards guarding there, and there are tens of thousands of people watching this place, so they have to consider the consequences if they want to take action.

If the news gets out, it will be difficult for them to appear in public again.

"Hmph!" Seeing Lin Han and the others leave, Wang Qiankun curled his lips in disdain, and a hint of cold murderous intent flashed in his eyes.

"You're still far from being able to fight me, but you know too much, so it's still necessary to eliminate you. That guy should be here by now, 10 million, don't let me down!"

Wang Qiankun greeted many reporters who came up for interviews, while Lin Han and others left the stadium along the competition passage.

"I'm sorry, those keys still fell into Wang Qiankun's hands." Lin Han sighed and looked at Liu Qinqin beside him with an apologetic look.

But Liu Qinqin didn't seem to care, she shook her head.

"Forget it! You've tried your best. It was Wang Qiankun who was too insidious. Besides, we were all under house arrest at that time. It was impossible to be fair even if we wanted to."

Indeed, they were all under house arrest at the time. Although they had agreed to a competition with Wang Qiankun, everything was arranged by Wang Qiankun and they could not demand fairness.

Xiaoxiang also had no way to contact some well-known people to be the referee, after all, she didn't know them.

What's more, it would be dangerous if she showed up, as Wang Qiankun was most likely having people watching him everywhere.

Especially on Yueying's side, because Yueying is their friend, if they need help, they will most likely ask Yueying for help, so Wang Qiankun will definitely send someone to keep a close eye on Yueying.

Contacting her would put her in danger as well.

"I can only say that this is fate! I want to rely on my own strength to fight against Wang Qiankun, but it is obviously like an egg hitting a rock, and this result is reasonable."

Liu Qinqin has become more open-minded over the past few days because she had failed once before. Wang Qiankun had already seen through her plan and gave her a fake key to steal.

She had already lost at that time and should have accepted this fact. Lin Han gave her new hope, which was something Lin Han didn't need to do.

And she is not the kind of person who is greedy, so she can accept any outcome.
