Mu Tianyan frowned harder and harder, while his face gradually turned from pale to flushed, as if he was hanging on too hard that he would explode at any moment.
Seeing this situation, Lu Zijia sped up the transmission of spiritual energy and the worry in her eyes also became obvious.
More than two hours had passed very quickly. Mu Tianyan's face and the skin all over his body seemed to be burnt red, so red that it made people scared.
And his body even changed from trembling slightly to violently, as if he was enduring extreme pain. But even so, he still gritted his teeth and persisted.
This showed how strong his willpower was.
Noticing that the spiritual energy in her body was showing signs of depletion, Lu Zijia took out two pieces of emeralds from the space to absorb the spiritual energy inside.
At the same time, she saw from the corner of her eye that the silver needles inserted into Mu Tianyan's body were showing signs of turning black.
