How to describe a guqin?

The piano is very old, but the owner has preserved it very well and is very beautiful. If it were said that this was a piano that could kill a person instantly, no one would believe it, and no one wanted to believe it. The owner of Qin is so peaceful, there is no murderous intention in the house, the sky is so clear, no one wants to kill, let alone be killed. Suddenly the sound of the piano rang out, and all the guests were moved. Kou Yuanjie, the young master of the Demon Sect, was about to escape. Unexpectedly, he was about to move when he heard the sound of the strings suddenly burst out, like thousands of horses galloping, or like thousands of arrows shooting out. Suddenly, the piano came towards his face. The sound was filled with indescribable chills and screams. The man felt as if his body had been penetrated by thousands of arrows. He trembled all over and took several steps back. His face was pale and pale, and he was obviously injured. The trembling sound of the piano seemed to be answering, and it was also like a person laughing coldly, making people feel uncomfortable all over. Kou Yuanjie was unwilling to give up and immediately looked at the Moon Envoy beside him. Mingyue understood this in his heart, and rushed towards the back hall in a flash. Unexpectedly, before he entered the door, he heard the sound of the piano like arrows, and sharp whistles hitting his face. Mingyueshi changed his body shape several times, but was unable to avoid them all. He had to turn upside down and return to the original place. He saw that his clothes had been pierced by the sound of the piano, and his face changed color in shock. Ming Yue Shi and Hui Xin Shi took one look at it and quickly helped the young master up and retreated in a hurry. For a moment, the roar of the two people was heard outside the door. Under the greetings of the two people, more than a dozen Demon Sect believers protected the young master and left in a hurry. A few lively notes floated out of the room, like a girl's silver bell-like laughter, full of mischief and joy after playing a prank, completely different from the previous chilling and sinister birds of prey. After a while, the sound of the piano faded away, but the lingering sound still lingered around. As the girl's fingers jumped, notes gushed out from the strings like running water, spreading in the pavilion, soaking and surrounding people. The remaining guests sat down in the pavilion and listened to the gentle sound of the piano. At the beginning, it was just pleasant notes in my ears, but gradually I felt that my body and mind were completely immersed in the sound of the piano, and my heart was as happy as traveling through the nine heavens. Everything in the world was passing by like a fleeting cloud, which made me feel a little confused. It's a pity, and there is relief like letting go of a huge burden.

The sound of Shaoshi's piano slowly dispersed, and the other guests let out a long sigh of relief.

I worked very hard on this. Some of it was written by myself, and some of it was modified by others.
