"Don't ask me, I've only just recently apprenticed myself." Zhao Xing was also puzzled; he truly didn't know of any illustrious deeds Liu Tianning might have had in the past.
As for Liu Tianning's strength, he did have a rough guess.
Lao Liu was a Military Minister of Agriculture Officer from the Self Sect, and his Grassman Skill was unrivaled in the world. His case was an extreme one, and though of the fifth-rank, he likely possessed fourth-rank combat strength.
As to which level of the fourth rank he could contend against, Zhao Xing wasn't clear. After all, Lao Liu had only made a move once at the Sacrificial Soul Pass and hadn't engaged in a real battle.
But judging by the number of Grassmen from the Ten Thousand Skill Palace, Zhao Xing estimated that Liu Tianning could hold an undefeated position among the fourth-rank.
