The Ark of Noah was indeed that military helicopter number seventeen.
Using her knowledge, Seventeen designed a set of devices to simulate the human body environment.
Initially, Seventeen had successfully extracted Forsythia Brown's uterus along with Beas, and placed it within this simulated human body environment device during a surgery.
Since then, this simulated human body environment had become Beas's surrogate mother.
(Flower Talk: The birth of Beas is rather mystical, a phenomenon beyond the scope of typical medical knowledge, so please don't use professional medical knowledge to verify Beas's birth. Just take it as entertainment. Who knows, maybe in the future, such things will really happen, haha!)
Today, an anomaly occurred in the simulated human body, and Seventeen, excited, stayed by its side and witnessed the birth of Beas.
