First, there were the impossible trials in the labyrinth, a single rank 3 cultivator, no matter how strong it was, couldn't face them alone.
Second, the trials had specific requirements, be it flight, teamwork, or ability to fight in the darkness, the tests could be passed only by teams that were prepared for every situation.
Then, it was time for the ninth trial, where only those with the best survival instincts would survive.
Also, those cultivators had to have methods to slow their descent to survive the fall toward the seabed.
In the end, there was the journey toward the mountain ranges, where one had to survive against enemy ambushes and fight to protect its rewards.
Once inside the corridors, an opposing team that matched your level would appear.
'And now the corridor divides itself into five branches, which is precisely the same number of cultivators in our team. This can't be a coincidence.'
Noah's thoughts brought him to that conclusion.
And here we are, 400 chapters and still in the human ranks.
I thought I would need about 1.500 to end this story, I was wrong apparently xD
As always, thanks for staying with me!
