Seeing the cooked duck snatched away right under his nose, Li Yixian naturally could not accept it. Even if Lu Wushuang was stronger than him, it made no difference. But he also understood that now that Lu Wushuang had obtained the ancient pill, he would never return it so easily.
Li Yixian understood the principle of courtesy before force. Thus, at first, he brought Qu Wu, the Vice Palace Master who had come with him to search for the ancient pill, before Lu Wushuang. He wanted to discuss what price he would need to pay to "take back" the ancient pill from Lu Wushuang.
Without even considering his old neighbor's words, Lu Wushuang directly stated that he needed the item as well. It concerned his Dao Path, and he could not yield. Besides, now that the thing was already in his hands, what reason was there for him to give it up? Let alone Li Yixian, who was weaker than him—even if Qin Huang stood before him, he would argue his case to the bitter end!
Seeing Lu Wushuang's attitude, Li Yixian was somewhat helpless. He had not wanted to fight the other man either, so he pointed out that he had discovered the ancient pill first. Those who saw it had a share, and he hoped Lu Wushuang could offer him some compensation.
By rights, Li Yixian's request was fairly reasonable. From a certain perspective, Lu Wushuang truly had cut in and snatched the other man's treasure, so he had intended to offer some compensation.
But at that very moment, a group led by Qi Zhan happened to arrive, interrupting Lu Wushuang's actions. He could see Li Yixian's unwillingness, so he incited him to seize the ancient pill from Lu Wushuang's hands, promising to lend aid in the battle.
