When Lu Han saw the phrase "enduring the pain of absence" that Tang Su had posted on TikTok, he had just completed another detoxification on his own. He had spent more than a month in seclusion studying poisons and then concocting a new medicine pill.
This time, Lu Hanyuan had formally intended to take Professor Ming as his master, but Professor Ming himself was unwilling.
Without the formal apprenticeship, Professor Ming still taught him all he knew.
As a result, studying began with meditative seclusion, isolating himself from the world.
No wonder he often vanished without a trace.
After the new medicine pill hit the market, it was immediately pre-purchased by those who had suffered from Poisonous Insect Poison.
Lu Han reinvested the money he had earned into his next research project.
