Transmigrating to Great Tang, I Aim to Become World Champion

After the zombie horde breached a base at the end of the world, Li Haotian, a base quartermaster, died in the attack. But he transmigrated to the early Wude era of the Tang Dynasty with a warehouse full of supplies, taking over the body of Li Chengqian, eldest legitimate son of Li Shimin, the future emperor of the Great Tang.

At this point, Li Shimin has yet to murder his brother and imprison his father. He is constrained at every turn, and his subordinates are urging him to rebel, but he still can't make up his mind.

Li Chengqian is bullied as soon as he arrives, and he refuses to swallow the insult. So he starts encouraging Li Shimin to rebel. He even begins a campaign to deify himself, determined to make everyone believe he is an immortal's disciple so he can become the third emperor of the coming generation.

He also brings out a host of high-tech products, improving the lives of the people of the Great Tang and strengthening its armies. Then he sets his sights on conquering the world, hoping to become its ruler.

But his plan to make himself a god nearly falls apart when his younger brother, Li Tai, is born.

Li Tai is clever, and Li Chengqian raises him to become a scientist. That means he knows there are no immortals or gods. Li Chengqian is at a loss, so he has no choice but to keep up the deception. If all else fails, he'll take Li Tai into the space and lock him away. After all, they've grown close, and he can't bring himself to hurt him.

Unexpectedly, Li Tai takes a liking to the even more advanced technology in the space. The brothers join forces and begin deceiving the whole world.

Once Li Tai is on board, Li Chengqian uses the longevity medicine that was most popular at the end of the world to keep the entire Great Tang moving forward with him, conquering the world together. With his younger brother Li Tai's space program, they then charge wildly toward the whole universe...
