Professor Su wasn't necessarily asking for Yang Ping's help, but he did encounter difficulties in this research, making it hard to continue pushing forward.
Actually, looking at the current results of his project, it's already quite successful. This kind of biocement can induce new bone growth to replace the old, with a porous structure, and provides enough strength for mechanical support. In the field of orthopedics, this is already a great original innovation.
However, Professor Su wasn't satisfied with just this. He wanted to go further by making the new bone induced by the biocement fill the entire pore structure and eventually replace the original biocement. He knew the issue was stuck with the formula, and he understood that finding the optimal ratio for the formula required a lot of trial and error, and perhaps even necessitated adding, reducing, or replacing existing substances.
