Marvel's Hogwarts Wizard

Facing Thanos and his countless alien warriors, Jerry stood atop the fire dragon and pulled out his magic wand:
"Avada Kedavra," "The Unseen Blade," "The Upside-Down Bell," "Petrify All," "Vulcan's Path"...
Behind him was an army of countless magical creatures.
……
Upon traversing the Marvel universe, Jerry acquires a peculiar panel that rewards him with little red stars for doing good deeds.
You can use Little Red Stars to travel to other magical mini-worlds to learn magic.
Consuming Little Red Stars can also refresh the mind and speed up the learning of magic.
To protect himself and his family, Jerry reluctantly embarks on a path of constantly doing good deeds to earn little red stars and diligently studying magic.
The protagonist has sound values, is not a saint, is not brainless, and has no system. His interface is only for time travel and refreshing his mind. All magic is acquired by the protagonist through learning and becomes powerful through research.
