A series of prompts appeared. After seeing them, Su Xiao understood what had happened.
This place, known as the Endless Desert, contained a very special kind of soul. Normally, these souls had no form or substance—provided they did not encounter other living beings.
When a living being encountered one of these souls, thanks to the protection of the Endless Desert, no one could detect the soul, but the soul itself would change.
For example, when Morey encountered a soul, it would immediately follow her. After following her for several minutes, it would break away. As long as Morey had not undergone mental beastification, the soul would transform into a mental beast and exist independently, without any direct connection to Morey or causing her to undergo mental beastification.
Simply put, this was the Endless Desert's defense mechanism. Everyone who arrived here would encounter its souls. The souls would transform into mental beasts, kill that person, and eventually regress into souls again—souls stronger than before.
The tentacle man and the scythe-wielding Bleach seen earlier were Zenas's and Wood's mental beasts. However, these mental beasts did not mean that either of them had already beastified. The mental beasts formed from the desert's souls were more like imitations of mental beasts.
The blood-energy avatar was different. It was not Su Xiao's mental beast. During the few minutes when the soul followed him, he had been fighting Roche, so of course he had released blood energy. After absorbing the blood energy, the soul failed to transform into a mental beast and instead evolved into a blood soul.
The blood soul was a very special existence. If he had been able to fight it one-on-one, Su Xiao's odds would not have been low. Unfortunately, he had never gotten that chance. The moment they met, the blood
