A master of fisheries was slapped into a different world by a grass carp, with only a broken piece of porcelain bought for 80 yuan. He squatted in front of an abandoned pond and said, "It can be saved." Then he spent his whole life paving a road from the bottom of the pond to the starry sky.
You think he is raising fish, but actually he is raising water. You think he is raising water, but actually he is raising roads. You think he is cultivating a road, but in fact he is cultivating a direction to the stars.
Purpose: A scientific researcher comes to a different world and promotes the progress of the entire civilization step by step.
