"But... the concentration is low. Do you want everyone to drink water in a cup?"


    "Oh, didn''t I say it? This thing is very convenient to be contagious. After a while, the people in Xiaolan''s class will become easy to learn! My summer vacation plan will be successful! Wait a moment, will it be slow to spread slowly like this? Can there be a faster way..."


    "Baiji classmate...I know you work hard, but..."


    "Okay, I decided, let''s concentrate the potion into powder and spread it from the upper wind!"


    Before Dr. Zhao could say anything, Bai Ji had borrowed the alcohol lamp without authorization. After igniting the alcohol lamp, she put a thick purple-black liquid cup on it.


    "Haha, this liquid can keep the crystallized powder after heating it. It''s amazing!"


    "Wait a minute, classmate Baiji, I haven''t approved it yet, as a doctor..."


    "Oh my, class is coming, forget it, I''ll pack the powder again in the afternoon. Dr. Zhao, please ask you!"


    Ignoring the school doctor''s objection, Bai Ji just hurried out.


    "Hey? Wait a moment, hey...hey."


    Dr. Zhao sighed helplessly watching the student union leave with great enthusiasm.


    How to say it, this child is certainly not bad by nature, but he is not very good at considering others.


    "And this thing...is really unsafe."


    She frowned and looked at the liquid that was heated and purified by the alcohol lamp.


    As the alcohol lamp heats up, the water is evaporated into the air and the remaining substances are left behind. As the time was about to be over, Dr. Zhao turned off the alcohol lamp and then placed the mysterious purple-black substance in the beaker.


    Magically, those impurities really separated into crystals after cooling, and they looked pretty shiny.


    "What the **** is this..."


    Because no students came here at this moment, Dr. Zhao also began to observe this mysterious substance when he was free.


    To test the smell of this thing, she put her hand half a meter above the crystal and carefully stroked it with her hands.


    "It''s tasteless..."


    The cautious doctor secretly made a judgment in his heart that this thing was not powerful.


    However, Wen Xinlan''s completely different attitude before and after drinking the potion is indeed worth caring about, after all, that behavior is a bit strange.


    Just then, a gust of wind blew outside the window.


    Dr. Zhao, who felt his nose itchy, was not careful and sneeze.


    Ha chi! !


    The airflow made the crystals in front of her scatter like stars.


    "Ahem!!"


    His nose and throat became hot in an instant, and Dr. Zhao couldn''t help but cover his mouth in pain and coughed repeatedly.


    Oops, why am I so careless?


    Will something bad happen? ?
