# Chapter 2620: Worth Every Penny
The white-haired old man quickly left.
Players from District 001 were slightly different from those in other districts. In any other district, someone would have long since come forward to discuss business with him, but in District 001, even after seeing his childhood persona and being tempted, they still didn't act. Instead, they waited until he made his request before proceeding with the transaction. Whether players or district government officials, they were all very straightforward.
Of the five players who came, only one was around Xu Huo's age. The other four, judging by appearance alone, were at least forty or older, and all were A-rank players. Whether in terms of secondary evolution level or mental strength, they should be among the top tier, with plenty of experience. What they wanted was simply to learn how to create a mental power materialized object with a certain degree of autonomous capability — they didn't dare hope for something with thinking ability like a person, but rather wanted to use this method to elevate their mental strength to the next level.
Fortunately, Xu Huo also wanted to see more spiritual worlds, so he began one-on-one exchanges with them that very day.
The core of Bai Kou's spiritual world was a massive mechanical gear assembly. Her method of performing mental interference was to create layered trapped spaces. Like Xu Huo's doors, her chains opening and closing repeatedly was also a process of deepening mental interference.
Dou Shengnan's spiritual world was a black ocean, assisted by a prop made from that special plant seed. No other tricks — she relied purely on intensity and endurance to render high-level players powerless to resist.
E Shu had integrated mental power into magic performances, excelling at using magic to interfere with people's cognition. Because magic performances were already deeply ingrained in people's minds as a form of entertainment, truth and falsehood became difficult to distinguish, making it easier for those being interfered with to fall into the trap.
But today, Xu Huo's horizons were expanded once again.
Among these five people, one person's spiritual world was a primeval forest. That's right — after materialization, the spiritual world became a primeval forest, where the mutated animals and plants responsible for attacking were symbols of the player's powerful mental strength. Only with sufficient mental power could these materialized objects exist for long periods and possess strong attack capabilities.
Moreover, the coverage range of this person's spiritual world was also very large. The mental power field was not limited to the area around the user; animals materialized from mental power could move freely throughout the entire spiritual world.
The second person's spiritual world was named "Suffocation Space." This player was not good at imitating the surrounding environment or creating new environments. His mental interference focused on the opponent's breathing rhythm. Once the spiritual world was activated, it was easy to make people feel suffocated and unable to breathe without realizing it. Some players had indeed suffocated to death in his spiritual world.
Xu Huo didn't press for more details, but this kind of subtle mental interference, though it took time to take effect, was very difficult to defend against.
The third player didn't reveal the core of his spiritual world. His mental interference only had a miraculous effect after the opponent confirmed they had been interfered with. It was said that once trapped, it was very hard to escape on one's own — one would be stuck on a heavenly path, walking until they died of exhaustion.
Xu Huo couldn't enter that state, so he missed the opportunity to see it.
The fourth person was a female player. Her spiritual world was very interesting. Like the other players, in the process of studying mental power usage, she no longer improvised interference methods based on the surrounding environment, but instead chose the method she was most familiar with and best at. Her spiritual world would cause players to unknowingly regress — not in terms of ability regression, but like a baby learning to sit, crawl, walk, and run, the player would regress backward. First, they couldn't run, then walking became difficult, until they couldn't even stand steadily on their legs.
Xu Huo called over an apprentice to test it while he observed from the side. Sure enough, after a longer period, not only did the person have trouble walking, sitting, and lying down, but their intelligence seemed to regress as well. They actually sat on the ground and cried loudly.
The female player withdrew her power in time and added, "Ordinary people might lose control of their bladder under this mental interference."
Finally, there was the young man. His evolution intensity wasn't as high as the others, but he was very good at combining environmental factors for mental interference. He had probably studied some psychology and was skilled at indirectly probing the psychology and behavior patterns of trapped people, which greatly increased the success rate of his mental interference.
Among the five, one could use materialized objects throughout the entire spiritual world, essentially turning the whole spiritual world into their control domain. Others specialized in one direction of interference, multiplying the interference intensity.
Xu Huo usually combined mental interference with the environment, mainly to extend the time opponents stayed in his spiritual world, hoping to affect their mental state without them realizing. Although he had compressed the "mental interference" process during evolution, achieving an effect similar to "mind control," this was often aimed at people far weaker than himself. Players with high evolution rates were hard to instantly "mind control" unless he used mental-type props.
These four people from District 001, after multiple evolutions, had greatly shortened the "mental interference" process. Their specific spiritual world core materializations, though seemingly simple, were very effective.
"You are all experienced seniors. When it comes to how to use mental power reasonably, I am far inferior to all of you. But since I've accepted the medals, I will definitely make sure you get your money's worth." A spiral staircase rose beneath Xu Huo's feet.
Along with the spiral staircase, a massive library tower also appeared, along with the table placed at the bottom of the library tower, and the core materialized object on the table.
"He dares to casually take this thing out and show it?" The female player reached out, but before she could touch the object, the core materialized object, along with the table, melted into a black shadow. After the black shadow spread across the ground, it swallowed the five people one by one.
Without resistance, they entered the library tower through the spiritual gate.
Compared to before, Xu Huo's library tower had increased in volume. Moreover, combining his conjectures about the forbidden zone space in the Night Tour instance forbidden zone, the floors and rooms of the library tower were no longer simply rotating and moving. Instead, they had added an effect like swapping drawers. Each room could be individually pulled out and exchanged with any room on any floor, further confusing people's perception.
Of course, it was impossible to trap four A-rank mental purifiers like this. So after they walked out of the library tower, every single one of them was thrown into the "Mirror Space."
Becoming transparent themselves surprised these experienced individuals. Soon they realized this was also a form of strong mental control, so they began to activate their own spiritual worlds, trying to break free from the control.
Xu Huo's "Mirror Space" wasn't very large, and he didn't really intend to fight them to a conclusion. So when their spiritual worlds activated, he decisively retreated, shrinking his spiritual world while releasing his childhood persona.
The miniature version of him took one step forward and disappeared into the primeval forest.
