At that moment, Thor really had run into something. After he began showing his strength, it was not only Thor and the lightning around him slaughtering lives, but also Mjolnir, constantly flying about, all for the sake of completing Thanos's task as quickly as possible.
Unfortunately, Thanos's demand was to slaughter half the life on this planet. Otherwise, Thor would have unleashed all his divine power long ago and destroyed the planet outright. Failing that, he could have scoured it with thunder, wiping out every life and object on the surface, instead of destroying the lives on this planet bit by bit as he was now, while carefully controlling the number he destroyed so it did not exceed the half Thanos had required.
Thor's actions went very smoothly. As he shuttled through the thunder and lightning, he met no obstruction whatsoever. This planet's civilization seemed to possess no extraordinary power, and its individuals were even weaker than the clansmen of Drax whom Ronan had killed. This massacre stirred not the slightest ripple in Thor's heart.
But things were different on Mjolnir's side. While Mjolnir was slaughtering on the other side, a sturdy figure blocked its path. At that moment, Mjolnir, which had been pressing forward unstoppably, suddenly paused, even its hammerhead trembling faintly...
Yes, Mjolnir had fallen in love again. After Clark, Robet, Peter Parker, and a whole series of people who could lift Mjolnir, another person recognized by Mjolnir had appeared—and his place in Mjolnir's order of recognition was not low, either!
Mjolnir's order was still very important. For example, Peter Parker did not rank very high in Mjolnir's order, which meant that if Thor and Peter Parker summoned Mjolnir at the same time, Mjolnir would definitely fly into Thor's hand.
But this did not mean Thor ranked highest
