In June, One Hundred Thousand Whys was published.
Pan Long had poured enormous effort into the series. He had entered the Classic of Mountains and Seas twice for it: the first time to draft it over three months, and the second to revise and finalize it over another three.
The series covered not only every path the previous six volumes of Basic Science might inspire or give rise to, but also all sorts of unclaimed paths one might encounter in daily life. It even explained subjects in the quantum realm, such as wave-particle duality.
Pan Long had made up his mind to sweep up every unclaimed path in natural science. He would not let a single one slip through!
To that end, the series had grown from twenty volumes to twenty-four. Every book was thick and hefty; stacked together, they stood taller than even a big Northlands man like him.
The series was naturally expensive, but it was worth every coin. Beautifully made and richly illustrated, it was even printed on paper of the finest quality. As long as no one abused it, it could probably withstand centuries of ordinary use.
The series proved far more popular than the earlier six volumes of Basic Science. Quite a few wealthy people bought several sets to give to their juniors.
