It's a Showdown, I Taught My Wife All the Black Techniques

Li Juncheng traveled through the parallel world and awakened to the black technology system, but at the beginning he just wanted to eat soft food. Married to a cute female doctor in the scientific research field, she secretly taught her all kinds of black technologies... Until one day, Su Hanyun won the Nobel Prize for scientific research many times, and she began to have doubts: "Husband, it seems that all my scientific research results are related to you. Could it be that you are a peerless genius?" Li Juncheng held the fishing rod and asked, "Have you ever seen a scientific research genius who fishes and bask in the sun every day?" Su Hanyun shook her head and stuck to it with a sweet smile: "I am so envious of Yingjiang aircraft carrier technology. If only I could design it casually!" The next day. She saw that Li Juncheng could float to the middle of the lake to fish for a parasol by simply splicing a few wooden boards together. In disbelief, she took the wooden board back to study and found that the ultimate answer to designing a super-large aircraft carrier was hidden in it. This evening. Su Hanyun wanted to hug her: "Honey, let's show off your cards. You can remind me at critical moments every time. Is it intentional or accidental?" ... ... Then came the third season, the defection of artificial intelligence, the ancient Blue Star Civilization, and the Battle of the Galaxy. Li Juncheng had no choice but to help the country roll up the technology tree himself. One day. The alien fleet came to the solar system and wanted to plunder the resources of Blue Star. Just after entering the atmosphere, thousands of rays of light flashed away, and hundreds of star battleships were cut into pieces. The alien commander was horrified: "Who are you?" "Dragon Kingdom intelligence officer, captain of the third team of [Star Troopers], and husband of Dragon Kingdom's scientific research goddess, Li Juncheng!" The situation of Blue Star was recorded by the commander, and the existence of Blue Star was exposed. At this point, humans have officially participated in the galactic melee.
