Desert Island Era: the Whole Class Travels Through Time and I Am the Only Fire Source

On the last class trip before the college entrance examination, the whole class of 42 people traveled to a desert island together. Forty-one girls. Lin Yue is the only boy. No fresh water, no food, no rescue signal. During the day, he searched for edible wild vegetables and shellfish in the jungle, and at night he huddled in a cave to prevent beetles larger than humans from getting in. While others were still desperately digging for fire, Lin Yue had awakened to the system of having many children and many blessings. The first reward arrives - [Super Fresh Water Generator], and the water crisis is completely solved. Then came [Eternal Bonfire] [Constant Temperature House Core] [Structural Solidification Rune]... While others were seeking survival, he had already led the whole class of girls to build desert island infrastructure. With magic technology at hand, all kinds of survival materials are at your fingertips, and you can easily create an invincible shelter. While others are still struggling on the edge of life and death, he already has all the capital to build a new civilization in this world. System upgrade + desert island survival + many children and many blessings + time travel through imagination + survival infrastructure + magical technology
