The matter of Qin Yu's root bone was already clear to Su Xihe and Liu Zixiao.
It's just that, for nearly three months now, there hasn't been the slightest change, so it's merely a matter of skepticism.
Although ancient texts do mention severe injuries that could lead to a decline in root bone, recovering from them is extremely difficult, almost impossible.
After all, even Su Xiyue's forced use of a forbidden technique did not damage the root bone, showing how severe such an injury would be.
It's normal for them not to believe it.
"Though I didn't perceive it in detail at the time, I felt that Qin Yu's root bone should have undergone a change, but whether it was an improvement, I couldn't determine."
At the time, Liu Zixiao wanted to ask Qin Yu after leaving the main hall, but there were too many people around, and those elders were secretly observing; any action would undoubtedly arouse unnecessary suspicion.
