I'm Already Eighty, Can I Be Invincible by Continuing My Incense?

Chu Chen traveled to the fantasy world due to an accident. He thought he would soar into the sky, but he didn't expect that his parents were killed by bandits, but he was bought by human traffickers and kept as a slave in the Chen family mansion for more than seventy years. Living in the Chen family is worse than even a dog. Finally, after being unable to work, he was left to fend for himself in the wilderness. But there is no perfect way. After being thrown into the wilderness, he happened to encounter the Chaos Saint who was poisoned and was asked to detoxify her. After detoxifying the saint, Chu Chen got an unexpected surprise and awakened the incense tree. That is to complete the task according to the Incense Tree, and the Incense Tree will give Chu Chen various rewards. With the help of the incense tree, Chu Chen became a martial arts disciple. Many years later, I looked at the cultivators from all over the world kneeling at my feet and the countless descendants surrounding them. Chu Chen couldn't help but reveal a smile on his lips: "Eighty is the age to make a career!"
