章 235: Qin Canglan's Arrival

It was about the Old Marquis being poisoned.

Su Mo investigated from the residence. He asked his trusted guard to carefully investigate all the servants in the residence who had the chance to come into contact with the Old Marquis's food and drink. He did not find anything unusual, so he ruled out the possibility of the attack being committed in the residence.

From this point, at least it meant that the interior of Marquis Manor was safe. The investigation turned toward the ingredients from outside the residence. The huge Duke Mansion had dozens of ingredients every day, and this did not include the oil, salt, soy sauce, and vinegar rice that they bought regularly…

This was a huge project. Fortunately, the heavens did not disappoint. Finally, this morning, his trusted guard caught a butcher selling meat.

"It's a butcher surnamed Hu."
