Rebirth: Obtain the Technology System and Take the Motherland to Take Off

[Patriotism + Technology + Interstellar War + Future World] In 2040 AD, Blue Star suffered an interstellar invasion, and human civilization rose up to resist. But in the face of the hopelessly huge gap in technology, human civilization not only did not give in, but even went to war with alien civilizations without fear of death in order to defend their homeland. In the end, the ultimate weapon was used in a desperate attempt: nuclear weapons, but mankind was still defeated and was exterminated. Lin Heng, who was reborn ten years ago in 2030, awakened the technology system. Facing an interstellar invasion ten years from now, Lin Heng is determined to change the future and develop the technology of human civilization to make it impossible for the invading alien civilization to come back. When controllable nuclear fusion is realized, mankind has entered the era of unlimited energy. When the first interstellar battleship belonging to mankind entered deep space, mankind entered the interstellar age. The speed of development of human civilization has frightened all civilizations in the universe. In the face of the invasion, Lin Heng made a domineering speech at the Universal Civilization Conference: There are barbarians from all directions. If anyone dares to invade, the great human fleet will destroy their civilization, their race, and their descendants.
