澜城的渔民们在修补渔网时，无意中发现了灯塔地下室的秘密。

六站点频率图

张大爷在灯塔地下室整理旧物时，搬动了一块松动的地板砖，下面藏着一张泛黄的地图。地图上标记着六个红点，用虚线连接成一个六边形——每个点旁边都写着频率数值，中心是18.7Hz。

这是第一张完整的六站点频率图，揭示了ARG叙事的全局结构：

• 午夜电台 FM 103.9
• 深渊信使 未知频率
• 深渊之眼 未知频率
• 房间404 未知频率
• 锈蚀之城 未知频率
• 沉没之城 潮汐频率

六个站点围绕18.7Hz形成共振网络，每七天同步一次。

潮汐协议初始档案

陈婶在整理灯塔旧档案时，发现了一份加密文件。经过几天的破译，她终于打开了文件——这是"潮汐协议"的初始档案，记录着六个站点同步频率的最初构想：

"当六个站点的频率同时达到18.7Hz时，深海之门将会开启。我们需要找到第六个站点，完成最后的连接。"

档案中还提到了一个关键日期：2026年8月15日——六个站点预计首次完全同步的日子。

渔民的最新歌谣

渔民们在原来的新歌中又加了新段落，唱的是关于六个站点同步心跳的故事：

澜城的海啊深又深

六个站点心连心

18.7的频率啊

是我们共同的声音

这首歌谣已经在渔船上传唱开来，成为了澜城的新名片。

ARG叙事联动

随着后日谈内容的上线，沉没之城与其他ARG站点的联动更加紧密：

• 玩家可以在沉没之城中找到指向其他站点的线索
• 六个站点将在特定时间同步共振
• 潮汐协议的完整故事将逐步揭开

English Version:

Fishermen in Lan City accidentally discovered the lighthouse basement secret while mending nets.

Six-Site Frequency Map

Uncle Zhang was organizing old items in the lighthouse basement when he moved a loose floor brick, revealing a yellowed map beneath. The map marked six red dots connected by dashed lines forming a hexagon — each dot had a frequency value written beside it, with 18.7Hz at the center.

This is the first complete six-site frequency map, revealing the global structure of the ARG narrative:

• Midnight Frequency FM 103.9
• Abyss Messenger Unknown frequency
• Eye of the Abyss Unknown frequency
• Room 404 Unknown frequency
• Rusted City Unknown frequency
• Sunken City Tide frequency

Six sites form a resonance network around 18.7Hz, syncing once every seven days.

Tide Protocol Initial Archive

Aunt Chen found an encrypted file while organizing lighthouse archives. After days of decryption, she finally opened it — the "Tide Protocol" initial archive recording the original concept of six-site frequency synchronization:

"When all six sites reach 18.7Hz simultaneously, the Deep Sea Gate will open. We need to find the sixth site to complete the final connection."

The archive also mentions a key date: August 15, 2026 — when all six sites are expected to fully synchronize for the first time.

Fishermen's Latest Ballad

The fishermen added a new verse to their ballad, singing about the six sites' synchronized heartbeat:

Lan City's sea is deep and wide

Six sites connected side by side

18.7Hz frequency

Is our common melody

This ballad has spread across fishing boats, becoming Lan City's new signature.

ARG Narrative Integration

With the epilogue content live, Sunken City's connection to other ARG sites grows stronger:

• Players can find clues pointing to other sites within Sunken City
• Six sites will synchronize resonance at specific times
• The complete story of the Tide Protocol will gradually unfold
