Yang Qi's greatest wish was to create a Nuclear Fusion Power Plant to solve the energy crisis faced by Dream Island. The theory of the Fusion Power Plant was already very mature, but the hardware could not meet the standard, so Yang Qi had to settle for second best, using an improved Nuclear Fission Power Station to generate electricity.
But Yang Qi never gave up on his research into nuclear fusion generation. The most critical point was that materials capable of withstanding temperatures over one hundred million degrees Celsius required for nuclear fusion could not be found in the outside world. Thus, even though Yang Qi's theoretical research on nuclear fusion was completely mature, he could not create a mature Nuclear Fusion Power Plant.
