Lu Yuanming decided to spend ten years developing in this plane.
On the one hand, he aimed to develop an industrial system at least at the level of a Third Level Cosmic Civilization, then construct Cosmic Warships and technology of the same level.
Lu Yuanming said he would lead the people of this world to escape from this plane, and this was no lie—he sincerely wished to do so and genuinely planned to act accordingly.
Humanity...
Lu Yuanming truly saw himself as The Decider for all humankind. This was not to say that he fancied himself some infinitely benevolent Saint, but rather he felt a real sense of responsibility toward humanity.
Moreover, he had memories of this world. He had parents and a younger sister here, and though he had few friends, this was indeed the world in which he had memories. There might be few ties, but this world was indeed his own!
