The discovery of Cobalt and Cerulean steam

It was almost evening and I had finished attending my last lesson of the day, it was around 7 pm and I had just finished an extra lesson with Mr. Chen, all of the prima Phoenix students were there. 

Most of the people there appeared as if they were ready to fall asleep the second the cranky old man faced the image displayer.

I, myself included.

The heaviness of my head was ready to bring my whole body down with me the second those eyelids came to a close.

I had to make sure they were social distancing.

Normally, I was normally alert and ready to learn, but everything he talked about was things I already knew. Maybe it was because of the rise in my level of understanding but I remembered more than I did during my first lesson with him.

During the lesson he talked about cobalt steam and cerulean steam, previously, I hadn't fully remembered this information, but it became much clearer after recalling it during Madam Liang's class.
