In Chapter 21 of ROCH, Guo Jing shows his prowess by firing 3 arrows which split Jin Lun Fa Wang's arrow, split JLFW's bow in half, and toppled Khubilai's flag.
Now obviously JLFW does not want his bow that he is holding in his hand to be split in half by GJ's arrow; it's a tremendous loss of face. Yet he could do absolutely nothing about it. Does this mean that if Guo Jing had wanted to, he could have killed JLFW right then and there with his arrow? It would seem that if JLFW could catch this arrow if it was aiming at him, he would also be able to catch the one aiming for his bow.
