Yun Qin pushed the coffin lid with all her might, but the heavy stone lid did not budge at all.
She could not use her evil energy because the coffin would absorb it, so she could only rely on her strength to open this coffin.
Suddenly, Yun Qin had an idea. She split out a strand of her golden mana and tried to approach the stone coffin.
However, the coffin only absorbed the evil energy wrapped around her mana, not the mana itself.
It worked! Yun Qin was delighted and quickly used her evil energy to wrap her golden mana into a bundle.
However, it was difficult for her to use her mana to begin with. The evil energy used to control her mana was absorbed when it approached the coffin. Therefore, Yun Qin could only carefully divide her evil energy into smaller portions. Once the coffin absorbed the evil energy wrapped around her mana, she would replenish it with more evil energy to stabilize the shape of her mana.
