Be a Consort in Another World and Start Infrastructure Construction from Live Broadcasting

"Run quickly! The evil couple from Dayun Kingdom are here to fight against the autumn wind again!" An eldest princess is possessed by the god of war and is invincible! A prince consort controls technology and the infrastructure is invincible! Unable to win after another, and unable to develop as fast as others, we can only try to please the legendary prince-in-law and talk to him about loss-making business, so we can barely develop and not fall behind. Unexpectedly, Yun State, which was originally broken and poor, could cause headaches to the surrounding big countries. No one knew that the evil prince-in-law whom countless people talked about was actually just an ordinary student who knew a few sets of boxing skills. The high-tech design drawings he produced, the scientific development system he created, and the artillery, spears and light bulbs he created all came from a small live broadcast room. The live broadcast room implanted in his mind.
