The discovery of hydrogen greatly encouraged Bi Lingkong.
She had long known her apprentice was reliable, and she knew Pan Long must have been confident when he asked her to conduct the lightning-strike experiment. But only when the experiment produced results could she truly set her mind at ease.
It was like going to a hospital. Even if the Doctor took one look and said, "Don't worry. I've treated this illness many times. The cure rate is practically one hundred percent," a patient would remain uneasy until he felt the treatment working for himself.
Now she had felt it working.
The results were striking and convincing.
She spent another day refining the procedure for producing hydrogen.
To Pan Long, the experiment was madness of the highest order—electrolyzing water with a direct lightning strike? Couldn't she make a battery? All she needed were metal plates and an acidic solution.
Even without acid, potatoes would do... Some companies even used potatoes as servers!
Potatoes could not actually function as servers, but a simple battery made from potatoes really was possible—he had seen videos of it in his previous life.
Forget it. As long as Teacher's happy, nothing else matters.
With that experiment complete, Bi Lingkong seemed to have found the key to a locked door. Inspiration poured forth.
She gathered all sorts of things and blasted them mercilessly with fierce lightning.
Through these experiments, she really did discover several more elements.
For instance, when she struck table salt with lightning, she discovered a strange metal that spontaneously ignited in air without a flame and, once she found a way to condense it, turned out to be lighter than water.
It was sodium.
When she struck an alkaline solution with lightning, she discovered a green gas with a powerful, irritating smell and considerable
