The End of the World Martial Emperor

"Wu, remember you want to be the King of Martial, not the God of Martial!"... Gathering the power of the world, Wu Ji returned to the time when the end of the world was approaching. This time he wanted to save everything, but although he was invincible along the way, success and failure also crossed. He couldn't take action easily, he could only wait for his strength to recover quickly. But there is no need to worry, because this time he is no longer alone, and all the heroic spirits will return with new life and fight with the God of War in all directions again! (To avoid misunderstanding, let me make it clear that the group portrait, farming, and half-system text summoning systems do not increase the protagonist's strength because of the invincible text)
