Zhang Heng looked at the old seal in his hand, but he couldn't find anything special about it.
It was just an ordinary stone. The material was no different from other stones that could be found everywhere on the road. The level of carving on it was also very poor, and it was obvious that it hadn't been made for a long time.
When Zhang Heng first saw it, he thought it was a prank carved on it, or perhaps it was a new work that an apprentice sculptor had used to practice, it was hard to imagine that such an inconspicuous object would help Sartrus and Dr. Baker avoid the nightmares for a period of time, and also help them avoid the monsters'attacks.
