Troubled Times: I Use Martial Arts to Control the World! Peace in the World!

I saw the demons massacring the living people and keeping the dishonest people in captivity. I saw human beings killing each other and corpses littering the fields. I saw emperors, generals and ministers trample under their feet loyal ministers and good generals and hundreds of thousands of living beings for the sake of the so-called overall situation. I also saw young children being cut open and disemboweled for an illusory elixir of immortality. Li Chenqing thought he could watch all this indifferently, and thought he could do the same. But he was wrong, he couldn't do it. China is huge, big enough to accommodate hundreds of millions of living beings! China is so small that all living beings are trying to deceive each other and kill them all! The success of the king and the defeat of the bandits are discussed in the world. How many people write about the war in troubled times? I will kill the dragon with my sword!
