Cultivation Starts with Battle Royale

Those who cultivate the truth should think of eternal life. Entering the escape dream, fighting against the moon spirit of the mysterious world. The grievances and hatreds among the monks, and the chaos and disputes among the forces. Let's see how the time traveler Zhang Xuan breaks into the world of cultivation. (This book has a system. I feel that the existence of the system will become weaker and weaker in the future. The writing style is half-baked, and I have given up treatment.)
