Rex did not know why, but the planet-grade teleportation portal seemed to have a slight glitch that made him arrive outside the inheritance ground.
This was the coincidence that enabled him to meet the battlefield.
Once he returned to earth's atmosphere, he started falling at such ridiculous velocities that he could barely see what was before him.
His free-fall speed was unnaturally fast but Rex was still perceptive enough to notice the battle raging below him.
It took every bit of his willpower and reaction speed before he was able to barely shift himself away from the path of one of his swords, his butt barely escaped the sharp edge of the sword.
"Phew!" Rex wiped his sweat as he finally fell.
Falling was not the end, the momentum of his fall was so much that like a somersaulting vehicle, he started bulldozing through the desert, sending sand dozens of meters into the sky and disrupting the battle even further.
"F*ck!"
"F*ck!"
