In fact, Sun Wuji knew from the beginning that he was the one he was looking for. However, he clearly knew that he would kill him himself in the future, but he still couldn't bear it. He still wants to use his best efforts to protect him. When he is injured, he will stand by his side and slowly understand his intention to deal with him. He also knows that since he can't avoid doomed love, he chooses to accept it and protect the person he wants to protect. When it was all over and Xuan Ji was happy, Wuji, the grandson in the room, was being punished. Sun Wuji has not been punished by his master for the first time, because he can't obey his master's orders to kill the whirlwind.
And Sun Tzu Wuji has been protecting the whirlwind from others. In the room, grandson Wuji fell to the ground trembling and was summoned to the sky by his master. The Buddha took his grandson Wuji to the lotus pond in the middle of the holy land. He said that the witch was about to break her fourth seal. If grandson Wuji doesn't kill him, then he can't fly if he lives, so no one can stop him. Master used magic to make his grandson invincible to see the scene of the emperor killing people thousands of years ago. He forced his grandson Wuji to kill the whole world.
