"I can't see what's behind the barrier," said Gu Ning with a big frown. She couldn't see through it, so she wasn't sure whether it was dangerous and whether they should continue to explore it.
"Let's go closer and throw something over," said Leng Shaoting.
After that, they moved closer to the barrier. Gu Ning took out an ingot of silver from the telepathic eye space and threw it to the barrier.
The ingot of silver hit the barrier and fell. It couldn't cross it.
"Could it be a time-traveling tunnel or something?" Gu Ning suddenly had such a bold idea, but she really thought it was a bit possible. After all, given her experience, she felt that nothing was impossible.
Hearing that, Leng Shaoting agreed it was possible, but didn't think it was very likely. There could be anything behind the barrier.
