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.
