Extreme Killing Immortal

My name is Xu Chong. I am an orphan. I have no special bloodline or a terrifying background. When he was still a baby, he was raised by an old beggar until he was seven years old, until he was beaten to death by a complete beggar. When I was eight years old, I was begging and was brought back to the sect by an immortal master. From then on, I embarked on the path of cultivating immortality, just like everyone else, just to pursue eternal immortality. However, later the sect disappeared, and I wandered around the world and became a casual cultivator. In order not to be killed by others, I cultivated each realm to the extreme, striving to achieve perfection and invincibility in each realm. Of the three thousand avenues, who said you can only specialize in one, but I insist on practicing both sword and body. The sword in the fist can defeat all methods. Extreme state body, invincible. To achieve the goal, whatever means necessary!
