After Zi Cang received the news of Tangyu's return, he immediately sought him out. However, Zi Cang didn't ask much about the situation with the Yanshan Sect. After all, his sense of belonging to the Yanshan Sect isn't that strong. Moreover, Zi Cang is focused on seeking the immortals and the Tao, and he doesn't bother with other matters.
What delighted Tangyu was that his brother Zi Cang had also reached the Eighth Layer of the Mystic Law Realm. This level of realm is indeed pleasing. But thinking about it, he understood. Although Zi Cang's talent has never been extraordinarily demonic, he has gone through many ups and downs and has also imposed self-sealing for five thousand years, cultivating his purported state to an extremely stable level.
With such a mindset and the careful guidance of his master, the True Lord of Long Sword, such progress is unsurprising. Of course, it also shows that the True Lord of Long Sword truly has an excellent eye.
