One could wonder, why didn't Veyrin show George the way to the Time or Fate Celestial Trial, the reason was simple, George had no way of conquering those places.
The more advanced the law, the harder the trial. One could count on fingers the people who had conquered any of those trials, in the whole history of the world.
Back when George was fighting for the relic, Veyrin had seen George draining his enemies Lifespan. It struck him to how similar to blood magic that effect was.
Although the two methods seemed similar, they were different from a certain aspect. Blood Magic could indeed absorb enemy lifespan through blood, but George's ability absorbed the lifespan directly.
The Tower of Blood had 5 floors, each representing a different ability of the Blood Law.
"Guys, I can only pass this trial alone, but I hope to see you safe as soon as I can return" George said emotionally. In the past years, his companions had always followed him around.
