Actually, the so-called Immortal Alliance is just a handful of people who recently stepped into immortality banding together for warmth.
The world knows that the immortality realm is rampant nowadays, so being in the immortality realm isn't invincible anymore; a single immortality realm person cannot act with impunity and roam freely!
However, if one joins forces with a few like-minded friends of the same level, and if they advance and retreat together, and swear a blood oath, then they can act with impunity and roam freely!
Just like how a single chopstick can be easily broken, but a bundle of ten cannot be!
Under this psychological state, the first immortality realm organization in the Transit Realm was established, called the Immortal Alliance. The alliance treats everyone equally, with no hierarchy, but entry requires one to be at the immortality realm!
Of course, although the banner of the Immortal Alliance has been raised, those who join are few and far between.
