Ye Su asked, "How far can you go with the help of foreign object?"
The Second Brother answered, "Haotian Taoism follows the Natural Law, which is wrong in the first place."
Ye Su was slightly shocked. "Why?"
"What is a foreign object? If you consider everything except our bodies as a foreign object, then armor is a foreign object; a sword is a foreign object; the Qi of Heaven and Earth is a foreign object as well. However, everyone uses them."
"We travel by horses and boats; we cook with knives and fire. The difference between human beings and animals is that we can use tools. How can we consider them foreign objects?"
Ye Su thought for a long time. "I thought you were a straight, staid, and stubborn man until today, but you are the wisest one."
"Etiquette is a rule: think and follow the reasonable rules." The Second Brother continued, "Even when facing thousands of people, I never step back. This is my style."
