The game is set in a chaotic era where countless civilians suffered, filled with turmoil and unrest. The story unfolds in this turbulent time, making many newcomers very interested in the plot. So, here is a detailed explanation of the Yan Yun Sixteen Sounds plot to help players who haven't experienced it yet understand the content better and increase their immersion in the game.

I. Opening
You will play as an orphan who was adopted. The story begins at a place called Huoren Clinic. Following the NPC's guidance, you will go to the second floor of Huoren Clinic. Although your adoptive mother Aunt Han had warned you not to enter, curiosity drives you to explore. Here, you will find a large amount of gold and silver treasures, a ledger, and a mask. These clues seem to suggest that Aunt Han may be hiding some secrets. Continuing to follow the clues, you will find a dry well covered by vines in the backyard.

II. Faceless People
After burning off the vines with a bow and entering the dry well, you will discover an underground palace below. Inside are many faceless people and a path leading directly to Weak Water Shore. As you proceed to the end of the underground palace, you will meet the leader of the faceless people and obtain a secret scroll. Reading it reveals that it contains highly confidential information. After practicing the martial arts inside, the protagonist falls into a hallucination.
In the hallucination, you will experience the perspective of the faceless people. You learn that these once-terrifying faceless individuals were actually young heroes who underwent facial reconstruction surgery to infiltrate the enemy camp as Khitan spies. Despite their failure, they chose to spend the rest of their lives in this dark underground palace to avoid exposure.

III. Weak Water Shore
Leaving the underground palace, Aunt Han's identity continues to puzzle us. To solve this mystery, we go to her room but find her absent. Just as we prepare to leave, we encounter Yidao, and a group of black-clothed men suddenly appear outside the room, intending to kill us. To survive, we decide to temporarily cooperate with Yidao, fighting the enemies outside. Together, we easily defeat them.
To uncover the mastermind behind this, we deliberately spare one of the black-clothed men and follow him. We trail him to a wine cellar, but he disappears when we turn around. We continue deeper into the cellar, only to be separated from Yidao by a sudden trap door.

IV. Exploration
We continue exploring alone, defeating enemies along the way until we escape outdoors. Yidao informs us that Aunt Han seems to be protecting a secret crucial to many lives. Moving forward, we trigger a battle with Xin Xin, a heart demon resembling Aunt Han. After defeating her and waking up again, we find ourselves following Aunt Han to Buxianxian. When we ask her questions, she does not give a direct answer but tells us to copy scriptures as punishment.
V. Bodhi Bitter Sea
Continuing our exploration, we reach Bodhi Bitter Sea and encounter the boss Ye Wanshan. He has two challenging phases. After successfully defeating him, we enter a hallucination like the faceless people. In the hallucination, we learn that Ye Wanshan was once the Ironheart General of Yanbei Alliance. Even when besieged by the Khitans, who threatened him with his wife and children, he did not abandon the city.
He defended the city until the last moment, but due to insufficient troops, he had to retreat. For years afterward, he continuously advised the court to launch a northern expedition. However, the court always delayed, citing poor timing. Eventually, driven by hatred, he disguised himself and his subordinates as Khitans, massacring innocent civilians to provoke the court into war.

The detailed explanation of the Yan Yun Sixteen Sounds plot ends here. The story adopts a fragmented narrative style, integrating various plots into the exploration gameplay. Through this, players can experience the betrayals of the weak and incompetent court, the selfless dedication of the faceless people, and other dramatic stories through hallucinations.
