The laboratory's door was slammed shut.
Outside the door, Osborne and Ni Shengtao looked at each other confusedly, thinking in unison, "What's going on? The commander doesn't need anyone's help? Commander Cook didn't seem to be like this when he was researching potions in the past. "
Extremely puzzled, Ni Shengtao asked, "Has Commander Fang Heng always done potion research like this? "
Osborne recalled for a moment and nodded slightly.
"Huh? " Ni Shengtao responded.
Osborne didn't know how to explain. He just nodded and said, "Wait patiently. "
The matter was very important. The two of them didn't have the intention to leave. They just stood guard at the door, worried, waiting for Fang Heng's new orders at any time.
In the room, Fang Heng waited quietly.
Ten minutes later, rays of one alchemy magic array after another appeared on the hall's floor.
