Harrison Clark planned to study at least ten thousand sub-civilization development systems and two hundred thousand special planetary systems, which is about one-tenth of the total amount of cosmological knowledge currently mastered by humans.
However, a hundred years later, he only completed less than one percent, and only successfully visited less than two thousand planetary systems.
He really tried his best.
He was like Sisyphus pushing a stone. According to the pre-calculated optimal route, he would advance, arrive, read, leave, advance, arrive again, and read again...
Thus, he repeated the cycle, going on eternally without an endpoint.
His knowledge grew rapidly, but compared to the vast amount of knowledge available, it was still just a drop in the ocean.
Harrison Clark still hadn't found anything that impressed him.
But he was not in a hurry; he had already gotten used to searching for light in a pitch-black future.
