Lin Li wasn't particularly interested in the treasure, because the Tower of Dusk wasn't short of money like when it had just been established anymore. It had now stepped into a healthy developmental stage, and completely broke off its reliance on the wealth brought about by rare treasures.

The Malfa Family found Osric's adventure diary, which could hugely decrease the quest's risk, while the Dark Blade's speculations weren't just speculations. Lin Li was clear that no matter his old ally the Malfa Family or the new ally the Dark Blade, both concealed some information. However, this wasn't important. After all, who didn't have some secrets? This was an unspoken fact, and wasn't a matter of right or wrong. Whoever let out all that they had during a collaboration was too naive and foolish.
