Chapter 164

The Yin-Yang School has many supreme treasures, but among them, the most critical one has been lost for a long time.

After Su Xuan said this, Yan Fei immediately thought of what it was.

"The Phantom Music Box is actually hidden in the Mohist Mechanical City?!"

The Phantom Music Box has been lost for three hundred years. Nearly ten generations of the Yin-Yang School have tried to find it, but all ended in failure. By the time of the previous leader, Donghuang Taiyi, he also tried to find the Phantom Music Box.

Because the Phantom Music Box, besides being a supreme treasure of the Yin-Yang School, is also an important tool for penetrating a certain secret.

This secret is the "Seven Luminaries of the Azure Dragon"!

Yan Fei, as the Eastern Sovereign and Deputy Leader of the Yin-Yang School, knows many secrets of the Yin-Yang School by heart.

Thinking of this, she couldn't help but be shocked and couldn't help but look at Su Xuan.

'Did the Honorable Master Xuantian know these things long ago? That's why he mentioned the Seven Luminaries of the Azure Dragon first, and then the Phantom Music Box...'

Even if Yan Dan has a deep relationship with the Mohist School, and the Phantom Music Box is hidden in the Mohist School, there is no need to mention the Seven Luminaries of the Azure Dragon of Yan first. Although Yan Dan is the Crown Prince of Yan, he is not the King of Yan after all, and it is still unknown whether he knows the secret of the Seven Luminaries of the Azure Dragon.

At the same time, Yan Fei couldn't help but have other thoughts.

Does the Mohist School, which has always hated the upper-class nobles and mixed with the lowest commoners, have entanglements with Yan Dan, the Crown Prince of Yan, because of the Seven Luminaries of the Azure Dragon?

If, as Su Xuan said, the Phantom Music Box is hidden in the Mechanical City, and the Yin-Yang School has lost this item for three hundred years, in other words, the Mohist School is very likely to have obtained it for three hundred years.

The Mohist School has always been proficient in mechanical arts. Perhaps with the help of mechanical arts, they have already penetrated the mystery of the Phantom Music Box.

"How did the Honorable Master Xuantian know the whereabouts of the Phantom Music Box?"

After many thoughts flashed by, Yan Fei asked Su Xuan again.

Su Xuan's expression was calm. "I naturally have my own way to know these things!"

"Now, Yan Dan is about to come to Qin as a hostage, and he has a deep relationship with the Mohist School. Perhaps we can use him to explore the whereabouts of the Mohist Mechanical City."

"The supreme treasure that the Yin-Yang School has lost for many years is also time to return!"

"Yes!"

Yan Fei nodded and said yes.

Regardless of whether the Phantom Music Box is the key to cracking the secret of the Seven Luminaries of the Azure Dragon, this supreme treasure that the Yin-Yang School has lost for many years is indeed time to return. Of course, listening to the Honorable Master Xuantian's previous words, he seems to be quite interested in the Seven Luminaries of the Azure Dragon.

This secret has been circulating in the world for many years. The previous leader, Donghuang Taiyi, seemed to have understood part of the truth. He brought the Yin-Yang School to Qin, trying to use the power of Qin to obtain this item.

I don't know what kind of mystery it hides?

Yan Fei looked at Su Xuan again. Does Su Xuan know?

Moreover, the first place Su Xuan appeared was Han, and the fall of Han this time also had something to do with Su Xuan. Has that share of the Seven Luminaries of the Azure Dragon of Han already fallen into Su Xuan's hands?

Yan Fei had endless conjectures, but did not take the initiative to ask.

No matter what Su Xuan's purpose is, the Yin-Yang School has indeed achieved a second prosperity in Su Xuan's hands, and she has indeed gained strength from Su Xuan.

……

Time passed slowly.

Even though the land of Yan is remote, it seems that because of the King of Yan's fear of Qin, after receiving that letter, he immediately arranged to send his son to Qin as a hostage.

On this day, Yan Dan arrived in Qin.

The carriage passed through Xianyang. He sat in the carriage, casually pulled aside the curtain, and looked at the pedestrians on the street. The people walking on the street, whether men, women, old, or young, all had a deep sense of confidence on their faces.

This was a scene Yan Dan had never seen in Yan.

"Is this the difference between Qin and Yan?"

Perhaps it is precisely because of this confidence of the people of Qin that they are invincible when facing the other few countries. Even if they lose for a while, they can soon make up for it in other places and wash away their shame.

The land of Yan and Zhao has never lacked generous and tragic people from ancient times to the present.

However, generous and tragic ultimately carries the word "tragic." Heroes are indulgent, but it is because the present world is too cruel that they pin their hopes on the three-foot long sword worn by a commoner.

"Is the Crown Prince observing Qin?"

In the carriage, another person asked Yan Dan.

Yan Dan nodded. "Yes, I am indeed observing Qin. Since Qin changed from weak to strong, most of the wars in the world have been caused by it, but even I have to admit the strength of Qin."

"Yan does not want to start a war and only seeks self-preservation, but to seek self-preservation, one must first have the ability!"

"This time I am a hostage in Qin, one is to reassure the King of Qin, perhaps I can win a period of peace for Yan, and second, I also want to observe Qin and explore the secret of its strength. Perhaps, after returning to Yan in the future, I can imitate it."

"The Crown Prince has this heart, which is truly the blessing of the people of Yan!" Six-Fingered Blackie, who was in the carriage with Yan Dan, sighed softly.

A look of shame appeared on Yan Dan's face, and he could not help but lower his head.

Soon, the carriage arrived at the embassy of Qin.

Here, Yan Dan met the person who welcomed him.

Lord Changping Jun Xiong Qi. He is a relative of Chu, the maternal uncle of the eldest son Fusu. He once helped the King of Qin quell the Lao Ai rebellion. After Lu Lu Buwei was dismissed from his position as prime minister, he was highly favored by Ying Zheng.

This time, King Ying Zheng of Qin sent him to welcome Yan Dan, which also shows the importance he attaches to Yan Dan, his childhood friend in Zhao.

It's a pity that for Yan Dan, the friendship of that year had long since vanished.

If it weren't for the situation, he really didn't want to come to Qin.

……

Because Yan Dan just arrived in Qin and had not yet settled down in Qin, Six-Fingered Blackie decided to stay in Qin for a while.

Just as Yan Dan wanted to observe Qin and study how Qin became strong, for Six-Fingered Blackie, since he had come to Qin, he also wanted to observe Qin.

Before this, the places where he was more active were Yan, Zhao, and Qi.

Mohist disciples rarely walk in Qin, because since Qin became strong, most of the wars in the world have been caused by it. For the Mohist School, which advocates non-aggression, Qin is the tumor of the world.

Of course, this is the view of ordinary Mohist disciples and Yan Dan.

Although Six-Fingered Blackie echoed Yan Dan verbally, he still had his own views in his heart.
