"Done! I did it!"
Tharvis's cheerful voice broke the silence. Merlin turned to him and asked curiously, "Did you really finish it?"
It wasn't that he didn't believe him, but it had been too fast. Not even fifteen minutes had passed, yet Tharvis was already done, which felt a little unbelievable.
"Of course, Young Master. You can see for yourself," Tharvis replied proudly.
Merlin blinked twice, then walked over. When he saw the red liquid inside the tube on the desk, he rubbed his chin and asked, "Is this the final result? There's nothing else to add, right?"
Tharvis nodded slightly, crossing his arms over his chest.
"Yes, nothing needs to be added. It's sufficient and perfect. However, we still need to test it on someone infected with Blackpox to observe the reaction."
Merlin pondered for a moment before asking, "Does this potion have an expiration date?"
