My Super Chariot In Doomsday

In a world post-apocalypse, the streets lay abandoned, littered with cars and buildings, many still smoldering from the fires ignited by the unattended gasoline.  A week into the apocalypse, these scenes of desolation were commonplace.
Parked on the side of the road was a massive object - a black, metal-colored chariot, over ten meters long and four meters tall.  To Gu Ming, this chariot was his greatest asset in this post-apocalyptic world.    The origins of the apocalypse remained a mystery, but Gu Ming had his chariot, and that was all that mattered.
Setting down his telescope, Gu Ming patted his dog, Lucky, and lifted his four-year-old daughter into his arms.  Her innocent expression, round face, and small mouth were his beacon of hope amidst the despair. Despite the desolation he had witnessed, his family of three remained intact, and for that, he was grateful.
On the day of the apocalypse, Gu Ming obtained his external accessories, a Chariot System, which required a vehicle.  Luckily, he had a truck, and when merged with the Chariot System, it transformed into a Super Chariot, a sanctuary for his family.
While survival was a struggle for most, Gu Ming, with his Super Chariot, was focused on upgrading his tank quickly, determined to create a happy life for his loved ones in this new world.
How will Gu Ming navigate the post-apocalyptic world with his Super Chariot and ensure the safety and happiness of his family amidst the challenges they face?
