Su Mo's question would remain unanswered for a time being.
Yet one thing was certain.
Without Yang Yi's knowledge, Su Tianyang had done many things.
This broken Snake Head Sword was proof of that.
"My father... after returning from the Ziyang Sect, spent the next few years under the guise of escorting, traveling in Jianghu. On one hand, he was in pursuit of the whereabouts of Li Siyun and a group of defectors.
"On the other hand, he must have obtained some clues and traced the owner of this Snake Head Sword.
"However, what exactly happened during that period remains another mystery for us."
Su Mo gently shook his head and placed the Snake Head Sword back into the box.
After a moment, he also put the Mandarin Duck List, the Golden Jade Cone, and two Mysterious Mechanism clasps into the box.
Although the box was not very large, the items were small; after filling it, there was still surplus space.
"Do you plan to hide all these things here?"
Yang Xiaoyun glanced at Su Mo.
