The Great Mission to Save My Brother [Quick Transmigration]

The Space-Time Administration has had a bit of a headache lately. Because of one employee's mistake, they recruited an exceptionally young employee, so little he had only just learned to walk and couldn't even speak very clearly. The employee in question had already been punished, but there was no way to send the child back. According to the rules, he had to complete missions to extend his life span. Looking at the tiny three-headed child with big, blinking eyes, the person in charge of missions was at a loss. What kind of mission could a child like this possibly do? In the end, the reliable Main System stepped in. They wouldn't need to give the child any particular role. He could just be a normal little kid and go to worlds on the verge of collapse because transmigrators had messed them up, to save the children of destiny. As for his identity, the little guy wanted an older brother, didn't he? Then he could just be the protagonist's little brother. And so, the little guy nicknamed Doudou set off with his System big brother to help, or rather, save, his big brothers in other worlds. Operation: Save Big Brother begins! Advance warning: Doudou is a naturally charming little heartbreaker and might be a bit of a flirt. No detailed explanation, as that would involve spoilers. Unless something unexpected happens, there will be a battle royale between the big brothers later on. At its core, this is a no-romance child-rearing story. Doudou is adored by everyone, and the plot may move a little slowly. Thanks for understanding! Here's an upcoming story: A no-romance, slice-of-life child-rearing story, "Childcare Rules [Quick Transmigration]" Blurb: While saving children who had fallen into the water, Bai Cen got tangled in water plants and lost consciousness. Even as he was passing out, he was still sighing to himself. I wonder if I ruined the children's spring outing. Everyone at the kindergarten had been looking forward to it for so long. He thought he was going to die, but then... Bai Cen fell into deep thought as he looked at the ball of light in the pure white space, which claimed to be a System. He had been chosen because he was an excellent preschool teacher. He was supposed to go to other worlds and care for children without guardians? Bai Cen said, "I can be a preschool teacher, but I may not be able to be a parent!" And these childcare rules... Respect the special dietary habits of young ones from different species? Different species...? Looking at the red-haired, red-eyed little vampire who had bitten him on their first meeting and drunk his blood, Bai Cen drew in a sharp breath. This is... a little hard to respect! Will all the kids I'll have to raise in the future be like this?! Upcoming Story 2: "The Little Prince Is Bound to a Gourmet System" A slice-of-life gourmet child-rearing story Blurb: After many years on the throne, the Emperor of the Empire still had no children. Not only were the legislators and ministers worried, but the people of the Empire, who adored His Majesty, were worried about the Empire's heir as well. There was even a hot topic on the Star Network that people bumped every day. #DoWeHaveALittlePrinceYetToday?# Finally, in the thirty-second year of His Majesty's reign, the Empress, who had been feeling unwell for several days in a row, received good news from the doctor. "Have you heard? We're finally going to have a little prince!" "Ahhh! This is wonderful! The little prince is finally here!" "I'm even happier than when I found out I was having a child, haha!" After the much-anticipated little prince was born, the royal family immediately released his photo. With the same deep blue hair as their emperor and a pair of purple eyes, the adorable little prince melted the hearts of the Empire's people. From then on, one new item became part of the daily routine for the people of the Empire: checking the Empress's personal account at the same time every day to wait for updates about the little prince. But when the little prince was a year and a half old and weaned, ready to start eating nutritional supplements, everyone received a bombshell: the little prince couldn't eat any of the children's nutritional supplements. So the people of the Empire started worrying again. Bound to a gourmet System at birth, the little prince had spent his whole life listening to the System describe delicious food and show him pictures of beautiful dishes. When he finally tasted his first nutritional supplement, he felt betrayed. Where's the delicious food you promised?! System: W-Well, you need to revive gourmet food first...
