It was almost unheard of for even the most powerful ancient martial clans to be able to cultivate a seventh-grade master these days.

But now, it turned out that whoever owned the Invincible Piano would definitely be able to reach the seventh grade!

Even though people could not simultaneously cultivate with the help of Invincible Piano, the value of it was still apparent.

The young guest who had mocked Jeff earlier went red in embarrassment. He could only mutter in a low voice, “But you have to repair it first..."

What he did not realize was, a lot of the representatives of the ancient clans present were already calculating the possibility of repairing the Invincible Piano in their minds to see if it would be a worthwhile investment.

Jeff continued, "On top of that, the Invincible Piano can increase the cultivation speed of the person playing it by three times."

This time, the guests could not conceal their surprise, and there were a lot of audible gasps throughout the room.

The cultivation speed would increase by three times?

They all remembered that the first treasure of the Bryant family, the three-colored jade dish, could only enhance one's cultivation speed by 1.5 times.

Apart from that, some pills could also speed up one's cultivation, but they were all high-grade pills and very expensive!

Even in the ancient martial clans, it was impossible for young cultivators to take high-grade pills at will.

As Jeff's words about the effects of the Invincible Piano sank in, everyone present finally realized the real value of the seventh-grade treasure.

“Mr. Cooper... Do you happen to know exactly how much money it would take to repair the Invincible Piano?" an elder asked, unable to contain his curiosity.

Jeff was glad that by revealing the properties of the Invincible Piano, he had managed to arouse the interest of many ancient martial clans.

However, his face fell when he heard the elder's question, and he hesitated to answer,

“What? Doesn't your family even know how much it would cost?" the elder prompted in a disappointed tone.

Gritting his teeth, Jeff replied, “As I told you before, the Invincible Piano was crafted by my ancestors over a century ago. Obviously, any object would deteriorate over time. To maintain the state of the Invincible Piano, my family had to spend a substantial amount of money on it.

Thanks to my success in the entertainment industry, I've made a lot of money over the years, but the majority of my income went toward maintaining the Invincible Piano. Moreover, when it was first damaged years ago in the fire, my grandfather and my father spent a large amount of the family resources on trying to repair it."

Jeff was known to the whole nation for his position in the entertainment field. Even though the public did not know how much money he earned exactly, they knew it should be enough for him to be one of the wealthiest men in the country.

Therefore, his simple and frugal lifestyle was the subject of fascination among his fans.

The general assumption was that he simply embraced thriftiness and didn't enjoy a luxurious and extravagant life.

Little did they know that three generations of Jeff's family had actually used most of their family assets for the maintenance and attempted repair of their greatest treasure, the Invincible Piano.

The elder who had initially asked about the cost of repair pressed his lips into a thin line, and the expression on his face flickered.

It seemed that the reason for the decline of the Cooper family was more grave than anyone could imagine.
