Pick up Something to Save My Brother

My name is Lu Yi. Once upon a time, there were four brothers on the Qiyuan ship: the eldest, Ding Zheng, was our fists and backbone; the second, Xiao Shuo, was our eyes and brain; the third, Zhuge Ming, was the fire that ignited the miracle; and I, the fourth, was the hand that kept everything running. Now, I'm the only one left. And the "tinder" left behind by the third child. It has been three years since the meteorite tide at Guanghan Monitoring Station passed. According to official records, Ding Zheng, Xiao Shuo, and Zhuge Ming all died in the line of duty, becoming another footnote on the monument of human exploration of the stars. No one knows what Zhuge Ming accomplished at the moment when the tide tore apart space. No one knew that at the last moment before the Qiyuan ship was swallowed up, he stuffed me and the secret into the only rescue cabin and ejected. I survived, guarding the legacy that Lao San sacrificed his life for - an artificial intelligence core he named "Lingshu". He said that this is the starting point of new life and a bridge between dimensions. For more than ten years, I have been like the most pious gravekeeper and the only technical ascetic, hiding in the depths of this abandoned mining asteroid, using stolen energy and picked-up parts to maintain the growth of the spiritual hub.
