Three days later.
Chen Jichuan left the Lotus Islands together with Yangg Biqing and Zhang Zong.
The Lotus Islands are located deep within the West Sea, about two hundred thousand nautical miles from the westernmost coast of Central Earth. The location is secluded, surrounded by reefs, making it difficult for large ships to enter, while small boats struggle to handle the ocean waves.
Yangg Biqing stumbled upon the Lotus Islands by accident. It was then that he discovered the hidden paradise within and met Huangfu Yu, the Sword Tower Master at the time.
As for Chen Jichuan, he relied on the 'Circular Light Skill' to calculate the location of the Taixu Sword Stele and then traced its trajectory to find the Lotus Islands.
The Sword Stele was hidden within the Sword Tower; it was a complete set of the 'Thunder' inscriptions.
This was a legacy of the Taixu Sword Sect.
