Chapter 270

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

After Su Xuan said this, Yanfei thought of what it was at the first time.

"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 Sect Master Donghuang Taiyi, he had also tried to find the Phantom Music Box.

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

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

As Dongjun and Vice Sect Master of the Yin-Yang School, Yanfei knew many secrets of the Yin-Yang School by heart.

Thinking of this, she could not help but be horrified and could not help but look at Su Xuan.

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

Even if Yan Dan had a deep relationship with the Mohist School and the Phantom Music Box was hidden in the Mohist Mechanical City, there was no need to mention the Seven Luminaries of the Azure Dragon of the State of Yan first. Although Yan Dan was the Crown Prince of the State of Yan, he was not the King of Yan after all. Whether he knew the secret of the Seven Luminaries of the Azure Dragon was still unknown.

At the same time, Yanfei could not help but have other thoughts.

The Mohist School, which had always hated upper-class nobles and mixed among the lowest-class people, would have entanglements with Yan Dan, the Crown Prince of the State of Yan 930. Was it also because of the Seven Luminaries of the Azure Dragon?

If, as Su Xuan said, the Phantom Music Box was hidden in the Mechanical City, and this object had been lost by the Yin-Yang School for three hundred years, in other words, it was very likely that the Mohist School had obtained it for three hundred years.

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

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

After many thoughts flashed by, Yanfei asked Su Xuan again.

Su Xuan's expression was calm, "I naturally have my own way to learn about these things!"

"Now, Yan Dan is about to come to the Qin Guo 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 treasure that the Yin-Yang School has lost for many years is also time to return!"

"Yes!"

Yanfei nodded and said yes.

Regardless of whether the Phantom Music Box was the key to cracking the secret of the Seven Luminaries of the Azure Dragon, this treasure that the Yin-Yang School had lost for many years was indeed time to return. Of course, listening to Lord Xuantian's previous words, he seemed to be quite (aied) interested in the Seven Luminaries of the Azure Dragon.

This secret had been circulating in the world for many years. The previous Sect Master Donghuang Taiyi seemed to have understood part of the truth. He brought the Yin-Yang School to the Qin Guo, which was to try to use the power of the Qin Guo to obtain this object.

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

Yanfei looked at Su Xuan again. Did Su Xuan know?

Moreover, the place where Su Xuan first appeared was the State of Han, and this destruction of the State of Han also had a certain relationship with Su Xuan. Did that share of the Seven Luminaries of the Azure Dragon of the State of Han already fall into Su Xuan's hands?

Yanfei gave birth to endless conjectures, but did not take the initiative to ask.

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

Time passed slowly.

Even though the land of the State of Yan was remote, it seemed that because of the King of Yan's fear of the Qin Guo, after receiving that letter, he immediately set about arranging to send his son to the Qin Guo to be a hostage.

On this day, Yan Dan arrived in the Qin Guo.

The carriage passed through Xianyang. He sat in the carriage, 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 the State of Yan.

"Is this the difference between the Qin Guo and the State of Yan?"

Perhaps it was precisely because of this confidence of the Qin people that they were invincible and could conquer everything when facing the other countries. Even if there was a defeat, they could quickly make up for it in other places and wash away their shame.

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

However, generous and tragic ultimately carried the word "tragic." Heroes were indulgent, which was actually because the present world was too cruel, so they would pin their hopes on the three-foot long sword worn by a commoner.

"Is the Crown Prince observing the Qin Guo?"

In the carriage, another person asked Yan Dan.

Yan Dan nodded and said, "Yes, I am indeed observing the Qin Guo. Since the Qin Guo grew from weak to strong, almost half of the wars in the world have been caused by it, but even I have to admit the power of the Qin Guo."

"The State of Yan does not want to start a war and only seeks self-preservation, but if you want to preserve yourself, you must first have the ability!"

"This time I am a hostage in the Qin Guo, one is to put the Qin Wang's heart at ease, perhaps I can win a period of peace for the State of Yan, and secondly, I also want to observe the Qin Guo and explore the secret of its strength. Perhaps, after returning to the State of Yan in the future, I can imitate it."

"The Crown Prince has such a heart, which is truly the blessing of the people of the State of Yan!" Liu Zhi Heixia, 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 the Qin Guo.

Here, Yan Dan met the person who welcomed him.

Lord Changping Xiong Qi, he was a foreign relative of the State of Chu and the maternal uncle of Young Master Fu Su. He once helped the Qin Wang quell the Lao Ai rebellion. After Lu Buwei was dismissed from his prime ministership, he was highly favored by Seeing Ying Zheng.

This time, Qin Wang Seeing Ying Zheng sent him to welcome Yan Dan, which was also the importance he attached to Yan Dan, his childhood partner in the State of Zhao.

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

If it were not for the situation, he really did not want to come to the Qin Guo.

Because Yan Dan had just arrived in the Qin Guo and had not yet settled down in the Qin Guo, Liu Zhi Heixia decided to stay in the Qin Guo for a while longer.

Just as Yan Dan wanted to observe the Qin Guo and study how the Qin Guo became powerful, for Liu Zhi Heixia, since he had come to the Qin Guo, he also wanted to observe the Qin Guo.

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

Mohist disciples rarely walked in the Qin Guo, because since the Qin Guo became powerful, most of the wars in the world were caused by it. For the Mohist School, which advocated non-aggression, the Qin Guo was the tumor of the world.

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

Although Liu Zhi Heixia echoed Yan Dan verbally, in his heart, he still had his own views.
