You were asked to impersonate the King of Qin, not to become emperor!

"Oh no, why does the Princess ask so many questions? He definitely won't be able to answer the secret codes!"

Wang Qingyi's heart skipped a beat.

The Crown Prince and the other princes were waiting for Chen Xuan to be unable to answer.

Judging from the princess's expression at this moment, she was clearly suspicious.

"Sister, do you really want me to say it in public? That was our secret code when we were kids..."

Chen Xuan blushed and stammered.

Chen Yu immediately understood. The slogan was indeed somewhat private, but it was also an important basis for proving his identity as the King of Qin.

"Stop wasting time! If you know, you know; if you don't, you don't..."

The sixth prince couldn't wait any longer and was the first to step forward and urge them on.

"So noisy!"

Chen Xuan glanced coldly at the Sixth Prince.

The sixth prince's face turned ashen from being rebuked. Although he was the most suitable candidate to compete for the throne among all the princes, apart from the crown prince and the Prince of Qin.

But right now, he has not yet been made a king; he is still just a prince.

Being of lower status, he naturally dared not confront the King of Qin head-on.

Chen Heng said coldly, "Imperial brother, are you unable to answer and are taking your anger out on sixth brother? Or are you not fourth brother at all?"

"Your Majesty, the Prince of Qin doesn't even know the secret signals he uses with the princess; his identity is highly questionable. I implore Your Majesty to investigate this matter thoroughly!"

Zhang Xianzhao took the lead and applied pressure layer by layer.

Following Zhang Xianzhao's lead, civil officials and aristocratic groups echoed his sentiments.

Emperor Jin glanced at Chen Xuan and said, "Speak plainly, and I will pardon you!"

"Thank you, Father Emperor."

Chen Xuan cupped his hands and turned his gaze to Chen Yu:

"Hoping for the moonlight to enter the house, the quilt is half empty, the sound of washing clothes has not yet ceased... Your Majesty, are these coded messages correct?"

Chen Yu was startled.

Chen Xuan's words were absolutely correct.

Emperor Jin was also very curious about whether Chen Xuan's words were correct, and looked at Chen Yu, reluctantly asking:

"Princess, is the King of Qin's answer correct?"

The ministers knew that the princess's answer was a matter of life and death for the King of Qin.

At this moment, everyone bowed their heads and held their breath, waiting for the princess's reply.

"Your Majesty is right," Chen Yu said.

Upon hearing this, Emperor Jin nodded: "At this banquet, you siblings were able to reminisce about the past; such sentiments are rare."

As soon as he finished speaking, the ministers began to discuss among themselves.

They felt that the identity of the King of Qin was now secure, and the previous claim that the King of Qin was a stand-in was clearly unfounded.

But when Chen Heng saw this, his face turned ashen, as if he had swallowed a fly.

He turned to Chen Yudao:

"Your Highness, you can inquire about the past. This alone is not enough to prove that he is the King of Qin. To be on the safe side, please continue your questioning!"

Chen Yu was not offended, because she knew that this matter concerned the honor and disgrace of the royal family, and it was not unreasonable to be careful.

He immediately nodded in agreement, "I'll test the waters further..."

"Yes, it's best to set a trap for him and trick him a little. That way, it'll be easier to find out if he's telling the truth!" Chen Heng said.

Chen Yu nodded, then looked at Emperor Jin and said, "Your Majesty, all the officials are here at today's banquet. Why not have my fourth brother play a piece for them? I remember when we were young, my fourth brother was very skilled in a musical instrument..."

Upon hearing that the King of Qin was so talented, the Emperor of Jin was naturally overjoyed and said, "Granted!"

Although everything seems peaceful now, Wang Qingyi knows the eldest princess's personality very well.

This matter is not to be easily dismissed and must be handled with caution.

She whispered in Chen Xuan's ear, "Be careful..."

Chen Xuan remained calm. He wanted to see what tricks this woman was up to!

"Bring me the flute!"

Chen Yu said loudly.

At that moment, a palace maid handed Chen Xuan a jade-green flute.

The officials eagerly awaited Chen Xuan's performance.

"Your Majesty must be mistaken. I've never played this kind of instrument before!" Chen Xuan said with a wry smile.

As soon as he finished speaking, Zhang Xianzhao launched the first attack:

"The Princess just said that this is an instrument you, King Qin, are proficient in, but now you say you can't play it. Could it be that you, King Qin, are not a real one?"

As soon as he finished speaking, the civil officials followed Zhang Xianzhao and began to launch a barrage of attacks against Chen Xuan.

Chen Xuan looked at Chen Yu and said with a wry smile, "Elder sister, you must be mistaken. This is the instrument you're best at. You used to play it for me all the time when we were little. Have you forgotten?"

Just as everyone was confused, Chen Yu explained:

"The King of Qin is right. That was just a test. The King of Qin is not skilled in this instrument, while I am the one who is..."

Upon hearing this, the Jin emperor and his court officials suddenly realized the truth.

But then Chen Yu continued, "To express my apology, I have specially prepared a dish of food; please accept it, Your Majesty!"

Having said that, he took a plate of spinach and personally delivered it to the King of Qin.

Chen Yu thought to himself: The spinach is mixed with Sichuan peppercorns. Although the King of Qin likes spinach, he never touches Sichuan peppercorns. If he eats the spinach directly later, it will undoubtedly be a lie…

The officials all knew that Chen Yu was testing the King of Qin, but they were all clueless and completely confused...

"Royal sister, this dish of spinach is such a waste," Chen Xuan said, shaking his head helplessly.

Chen Yu laughed and said, "This was prepared by a top-notch imperial chef. What's there to regret? Could it be that there's something wrong with how this dish of spinach was cooked?"

Sichuan peppercorns paired with spinach—this is a dish that's absolutely perfect in Central Plains cuisine.

Therefore, Chen Yu was also very curious about how Chen Xuan would answer next!

"This dish of vegetables is delicious, but it's covered in Sichuan peppercorns. I don't know how my brother can eat it!" Chen Xuan said.

"Sichuan peppercorns have a flavor-enhancing effect, so why couldn't the King of Qin bring himself to eat them?"

"Your Majesty, you know that my favorite food is spinach, but my least favorite ingredient is Sichuan peppercorns. Although this dish of spinach may whet my appetite, I can't swallow a single drop because of the Sichuan peppercorns. Please forgive me, Your Majesty!"

Chen Xuan didn't touch the plate of spinach and immediately apologized.

Everyone then realized that the princess had sent the spinach as a way to test Chen Xuan.

At this moment, Wang Qingyi felt a tremor in her heart.

He was very curious as to why Chen Xuan, who was just a beggar, remained so calm throughout.

Moreover, those matters were private affairs between the King of Qin and the Princess, and he not only knew about them, but knew them so thoroughly!

This left Wang Qingyi completely bewildered.

"Hahaha!"

Chen Yu chuckled and said, "Someone, change the dishes for the King of Qin!"

Immediately afterwards, palace servants brought in five or six plates of spinach.

Chen Xuan's mouth watered as he looked at the lush green spinach, and he began to eat it in large mouthfuls.

Actually, Chen Xuan didn't like spinach.

But during those three days, he frantically searched for the past between the Crown Prince and the Eldest Princess, and even sneaked into the Eldest Princess's residence without anyone noticing, read through the Eldest Princess's diary, and eavesdropped on the Eldest Princess's recounting of the past.

Therefore, he was able to resolve the princess's difficult demands one by one without arousing suspicion.

When Chen Yu saw Chen Xuan eating spinach, he no longer cared about the pictographic representation and had already accepted in his heart that Chen Xuan was the King of Qin.

"Brother, after several tests, it's enough to prove that he is the King of Qin. I can confirm it now!" Chen Yu said.
