Three days later.
Thanos arrived in an unknown star system beyond the Milky Way, picked a star at random, and flew straight into it.
The star was unremarkable, just over fifty million kilometers across—neither particularly large nor small.
Its temperature and pressure were fairly moderate too: over three thousand degrees at the surface and several hundred times standard gravity.
This time, though, he barely felt any pressure.
As he plunged deeper into the star, even at a depth of over a hundred thousand kilometers, the pressure and heat scarcely bothered him. He did not even need Annihilation Power to strengthen his body.
He was pleased.
His cells had grown stronger as his body adapted to using Annihilation Power.
Now the effects of that strengthening were clear.
Of course, he had needed a strong body to begin with. Otherwise, his cells would have been destroyed faster than they could recover, and the strengthening would have failed.
After more than an hour, he reached the star's core.
Unlike a Black Hole, whose conditions he could no longer calculate, he could still make a rough estimate of the conditions here.
The temperature had climbed into the billions of degrees, and the pressure had reached hundreds of millions of times normal levels.
At last, he felt his body reach its limit and had to activate Annihilation Power to strengthen it.
As Annihilation Power surged through him, he felt his body grow stronger than ever before.
He reached out and activated the Star-Absorbing Technique, drawing in energy.
But absorbing energy inside a star meant using Annihilation Power to withstand the pressure and heat. That was hardly worth it, so he left the star and continued absorbing energy from outside.
Before he knew it, more than half a year had passed.
After absorbing energy from over
