What is the truth of the universe? Is it the unity of the four fundamental forces, or why does consciousness exist? Is the beginning of the universe really a singularity, and where will the universe end? For the earth, no one can answer this question. However, when Lin Xiao obtained the truth aid, finding the truth of the universe seems not so impossible. Truth requires basic knowledge one by one as the foundation, and then continues to extend upwards. From simple basic geometry to complex algebraic geometry; from ordinary elementary functions to the mind-boggling Riemann conjecture; from a decimal point to infinitesimal transformation; ... And these are still only the foundations of truth. But even the foundations have overwhelmed countless human geniuses. However, Lin Xiao will complete the breakthroughs on these foundations, from theory to application, from mathematics to biochemistry. from dirty oil to the brilliance of fusion; from special drugs for treating rhinitis to targeted drugs for radical cancer; from quantum mechanics and relativity to grand unified theory; the process of finding the truth is to solve various problems. The process of asking questions; and Lin Xiao will follow this process until he finds the truth.
