Agriculture professor Chu Jun has survived on a deserted island for three years. He relies on his systematic skills to grow sea rice and thousands of pounds of potatoes, and he lives a more prosperous life than anyone else. A storm unexpectedly brought together three "maniacs in ancient costumes" - the one in dragon robe called himself Ying Zheng, the one in armor called himself Wang Ben, and the one in court uniform was Meng Yi.
Chu Jun just thought that the crew was lost, and casually boasted that the yield of potatoes is four thousand kilograms per acre and that rice can be grown in sea water. Unexpectedly, Ying Zheng's pupils were shocked on the spot and he called him "immortal"!
Chop bacon with a precious blade given by the First Emperor? The First Emperor was not angry but respectful; wiped his butt with hemp paper? Meng Yi fights to save the sacred object; invites three people to fight mahjong gambling IOU? The emperor of the ages rolls up his sleeves to accompany you!
Lord Chu: "I'm really not an immortal, I'm just an agricultural person!" The First Emperor led his civil and military officials to kowtow devoutly: "Immortal masters, please don't be modest! Such divine objects can help the world, but they can't be immortals. I ask the immortal masters to follow me back to Qin and help me to pacify the world!"
From then on, the King of Chu relied on modern agricultural technology to start a win-win model in the Qin Dynasty - mountains of grain were piled up, and all the people worshiped him. Even the First Emperor wanted to listen to his popular science saying "there are no gods"!
