Ancient Tang Clan?

After saying that, Yun Lintian took the jade slip Nantian Xuanyu gave him out and placed it on the table. "You two have already read it once. Did the surname Tang ring a bell to you?"

A trace of astonishment appeared on Guchang and Mu Qiuxue's faces. They clearly remembered a powerful Tang clan of the Skymist Ancient City written on the jade slip.

There were four great clans served under the Skymist Ancient Clan, namely Tang, Sui, Zeng, and Shi clans. It was said each of them could easily rival any of the nine palaces in this era. 

Unfortunately, they met the same ending with the Skymist Ancient Clan by the sudden appearance of the violent windstorm.

The Tang clan was arguably the strongest among the four and the richest of all. On their glorious day, they could call the wind and rain on the Southern Continent as they liked. Their prestige was not inferior to the Skymist Ancient Clan in the slightest.
