Why Is This Bard so Full of Tang Poetry and Song Lyrics?

[Western Fantasy + Adventure + System + Sword and Magic] A dimensionality reduction attack where China and the West collide. Li Wei died suddenly during his final review, and when he opened his eyes, he became a bard from another world. He was tied to the execution bench in the lord's palace, with a red-hot iron and a knife in front of him to purify his body. The original owner was a bastard who specialized in deceiving noble ladies, and he took over the whole mess. Fortunately, he has awakened the "Word Spirit Poetry System": in this world where bards can only sing limericks such as "Warriors raise their swords and rush forward", he can turn Chinese poetry into real magic. The phrase "no one can be seen in the empty mountain" makes the enemy invisible on the spot, the phrase "burning like a fire" blows up the official road to the sky, and the phrase "kills one person in ten steps" inflicts heavy damage on the enemy like a ghost. But the price is not small: the church regards the ancient saying as heresy, offering a reward, and the witch-hunting team is pursuing him with devil dogs; the number of poems is limited, the magic power is at the bottom, and the emotion will backfire if he enters it too deeply. What's more terrible is that why the world recognizes Chinese poetry, where the system comes from, and how he can get home are all a mystery. From a heretic who was hunted throughout the city, to a famous singer in Salmon Harbor, to a guest of the Arcanist, Li Wei used a poem to fight his way out—— "When I finish memorizing the required articles for the college entrance examination, I will recite this route home sentence by sentence."
