Sichen, a descendant of Xihe, built a star platform on Tushan Mountain, burned tortoise shells, performed star trajectories, and launched an unprecedented "astrological live broadcast". The tribal leaders rewarded them with shells and told them about the good and bad times of the farming season. However, Xuanniiao made a mistake when summoning him, and the Gonggong clan denounced him as "confused the public"! Sichen held a ruler and measured the shadow of the sun. In order to break the illusion, he corrected the calendar with actual measured stars, letting the stars fall among the corn, igniting the first spark of science in ignorance.
