The metal cage for containing insects had very small gaps.
Yet it could escape through these gaps like water, which indicated that its body possessed the capability to morph.
This was also one of the most basic abilities of a Gu.
Disperse to become gas, gather to take form.
This Blood Spider had already begun to master this skill. The nine Taiyin Yaoyaos that Elder Jiu Yin kept also had this ability.
When they were a whole, the Insect Jar couldn't contain them at all.
Only by cutting them in half and imprisoning them separately could they prevent their escape.
When Elder Jiu Yin confidently left eight Taiyin Yaoyaos by the Tianshui River to deal with Master He Shan, he counted on their special ability to be impervious to swords and challenging to imprison.
With these two abilities, their safety was basically secured.
