People can get nothing without sacrifice. In order to get something, they must pay the same price. This is the principle of "equivalent exchange" in alchemy. It is also a universal principle.
No matter what world we are in, people live, cry, laugh, and die.
People are not different.
The existence of science must bring happiness to people. Alchemists are also scientists to a certain extent. Try your best to explore your own talents and create. Even if there is only a glimmer of possibility, you will try your best to get together with the people you love, hug and kiss, and return to the place where you finally belong.
