After the friendly match with Okita Soki, Zhang Heng's Lv.3 swordsmanship had finally broken through to Lv.4. To him, this was like stepping into a new realm. The promotion to each major level was a qualitative leap, not to mention Lv4, which was in itself a very rare achievement for anyone. After the upgrade, he could feel that his five senses had been considerably enhanced. Coupled with previous insight and combat experience accumulated by challenging various dojos, and the foundation built in Black Sail, Zhang Heng finally came up with his sect.
To commemorate this battle with Okita Soki, Zhang Heng decided to name the new sect Tendou-ryu. He also gained a new skill called Mind's Eye, allowing him to keep fighting even when his vision was impaired.
