With stored electricity now available, Senku moves on to the next logical scientific breakthrough—creating light bulbs. After several rounds of trial and error, the Kingdom of Science successfully brings artificial light into the stone world. To demonstrate this incredible achievement, Senku decorates a tree with glowing bulbs, turning it into a brilliant Christmas tree. This moment marks a huge leap forward, proving that modern technology is steadily returning and hope is brighter than ever.
