Da Qin: Alchemy Failed and Was Targeted by the First Emperor

After traveling through time and becoming a death row prisoner who failed to make alchemy, he will be beheaded on the execution ground. Zhang Ye silently opened the system and was rewarded: periodic table of elements. "Your Majesty, the main ingredient of the longevity pill you took is mercury sulfide - it is poison." The First Emperor shook his chopsticks, and all the alchemists in the court knelt on the ground. Later, the Yin and Yang family came to compare astrology, and Zhang Ye used astrophysics to calculate it again. The Yin Yang family is collectively autistic. The Mo family came to compete in machine skills, and Zhang Ye threw out a differential gear drawing. The Mohist giant doubts life. Confucians scolded him for disrespecting ghosts and gods, so Zhang Ye predicted the solar eclipse on the spot. The day * eclipses the sun, and the whole place is silent. Later, Zhang Ye discovered that something was wrong with the world. There are seven fragments of heaven hidden under the earth's veins, maintaining a huge lie - the earth is the refuge of civilization. And the "Great Nirvana" is approaching. The First Emperor asked: "Can it be blocked?" Zhang Ye thought for a while: "Yes. But we need to build an atomic bomb first." This novel and its characters are purely fictitious.
