"Since the Miracle Formula has given me this strange devouring ability, it must be beneficial to myself. If I worry too much and don't use it, wouldn't that be a waste of a shortcut to rapid evolution?" Mu Xiao wasn't a stubborn guardian of orthodoxy; he didn't think of this as an evil devouring ability that shouldn't be used. In fact, for the sake of evolution, as long as one doesn't abandon their basic human nature, they can use it without any reservations."

  The greater the power, the easier it is to lose one's true nature, and become a slave to genes, ultimately leading to the downfall of humanity, no longer human, but a demon.

  Evolution is not just about leveling up, sometimes mentality matters too.

  It's like what Taoists call "mental state", and in modern evolutionary terms, it's called "soul".

  This is the key to determining one's own hidden potential, because with too many evolutions, the "soul" will gradually become cloudy, and it is necessary to maintain a consistent principle of the "soul", not trying to destroy the baseline of one's own "soul", regularly purifying one's own "soul", so as to see clearly the path forward for one's body and evolution.

  If a person can't even guard their own "soul", then what qualifications do they have to become a flawless and perfect being?

  It's just that ordinary people find it hard to pay attention to the changes in their "soul", and as a result, they are corroded by the power of evolution, although on the surface they have no doubts about others, but in reality they have already gone astray, lost the correct path of evolution, and will eventually become either a "demon" or die from genetic collapse.

  Mushan has fallen deeply in the "Heart" realm before, so he is very clear about his direction of evolution and does not want to go back to his old path. Moreover, in the cultivation of the "Heart", this is the only intangible realm that cannot be improved by external means, and can only rely on oneself to 'meditate' and calm down complicated thoughts in order to continue improving one's realm.

  In this era of evolution, the "soul" is obviously not yet a concern for anyone, and many people are only indulging in the thrill brought by power, unaware of the fatal hidden dangers that rapid advancement can bring. Therefore, Mu Xiao emphasizes his own "soul" direction in advance, so as not to let his innate devouring ability become evil.

  Otherwise, under the subtle influence, one's "soul" is affected, and a distorted temperament appears, with a high probability of destroying one's own bottom line.

  However, some abilities are related to the "soul", and people of this type have a very clear understanding and feeling of the changes in their own soul. It's just that whether they can control the direction of their own soul without being tempted by external forces is another matter.

  ……

  Telekinesis pierced the corpse of a mutated human, tearing open a bloody hole in its chest, and soon a bright red heart full of blood energy was dug out by telekinesis.

  In mid-air, the dark red heart emitted a rich bloody fragrance, and Mu Shao's mental power slightly moved. The blood energy contained within the heart was compressed by his mental power into a thick, bright crimson liquid. He directly sucked it into his mouth, drinking it like a beverage.

  The heart can absorb all the blood.

  Suddenly, a fierce and intense energy burst forth from within his chest, causing his blood to boil like molten lava. His internal organs, muscles, and bones seemed to be set ablaze, as if he was bound to a scorching hot furnace. His eyes turned red, his skin flushed bright crimson, and steam billowed out of every pore on his body, giving him the sensation that his flesh was about to be steamed dry and roasted to perfection.

  Wow!

  The air was like a flame, his blood boiling like hot water, and gradually a layer of black impurities appeared on his body. His blood vessels were purified, the scorching temperature inside him began to drop, transforming into a warm and gentle current, like a spring breeze, softly nourishing every inch of muscle, dispelling the fierce and violent energy that had just been unleashed.

  "This is tempering the body's impurities..." Mu Xiao's eyes gleamed with a sharp, sword-like intensity, honed to a piercing edge.

  He clearly felt that his body had undergone a refinement, although no experience value was added, but the blood and gas in his body became more pure, high temperature evaporated excess fat on his body, all over his body were fine and dense muscles like iron water casting, with extremely explosive power, combat power even stronger than before.

  Now Mu Xiao's entire body has become full of vitality, his spirit is refreshed and his sense of touch has increased several times. The hidden diseases that remained in this body also underwent a refining and repair process.

  A thousand-mile dike collapses because of an ant hole.

  Hidden diseases in the body, if not taken care of, will cause more damage, new injuries covering old ones, and the longer it goes on, the more accumulated, the deeper hidden diseases will be harder to eliminate, greatly affecting the growth intensity of physical quality, as well as the speed and endurance of physical strength.

  "Indeed, the Heart Blood of a Variant has a great effect on me!" Mu Xiao moved his hands and feet, his body was as hard as cast iron, but also light and flexible, he simply swung a punch forward, and there was a faint gust of wind in the air.

  The mind is clear and refreshed, full of energy, for the first time feeling the great benefits brought by the "miracle formula".

  Because the "tempering" physique must use different sources, go through multiple strengthening and blending, or match with some precious medicine, that can achieve the effect of "tempering" physique. But now Mu Xiao only needs to swallow a variant human heart, he can skip the cumbersome steps and get a rare tempering effect.

  Especially now that his physique is only at the beginning of a new human, the faster he refines his physique, the more thoroughly his potential will be uncovered.

  "The metal door has electromagnetic energy flowing through it, which can slightly sense the presence of zombies outside. Now, if we set up some explosives at the entrance, tonight's safety should not be a problem." Mu Xiao rummaged through her backpack and took out three sensor bombs, three high-explosive grenades, tied them together, and arranged them in a triangular formation at the entrance.

  The remaining few hand grenades and bombs were placed separately by Mu Xiao at the corners of the stairs.

  If a monster really comes in, it will definitely withstand two explosion damages, and Mu Xiao on the second floor can also have enough time to prepare.

  ……

  On the third floor, in a secluded rest room, An Rongru sat on the bed with her mind racing. Her plump and mature face was flushed red-hot, her beautiful eyes sparkled like spring water, and as she indulged in wild thoughts, feelings of love began to arise. Her mature and plump body felt like ants crawling all over it, itching and numbness spreading throughout, exuding heat from every pore. Her heart was soft and sweet like honey, yet she couldn't help but scold herself for being shameless, and didn't know how to get through the long night ahead.

  It's not that An Rong Yu didn't want to become Mu Shao's woman, after all, she had experienced a day of continuous shock and fear, especially in the past when she was alone and terrified. When Mu Shao suddenly appeared to save her, wasn't he a hero saving a beauty? Moreover, every time Mu Shao gave her hope at the most critical moment, although some things were difficult for her, but thinking back, she also knew that Mu Shao was doing it for her own good, letting her adapt faster to this cruel world.

  However, An Rongruo has been a single woman for many years, long wary of men with ulterior motives, and has no sense of security in her heart. Now under Mu Xiao's multiple offensives, how can An Rongruo's seemingly strong but inwardly weak heart not be captured by the masculine power emitted by Mu Xiao?

  But after all, they had known each other for less than a day and had already ended up in bed together - she couldn't help but wonder if she was being too casual.

  At first, An Rongruo had promised to be Mu Xiao's woman, and she didn't want to go back on her word. Moreover, Mu Xiao indeed had feelings that moved her heart.

  "What to do... Refusing him doesn't seem quite right, if only he could understand me..." An Rongru looked like a lovesick maiden, as if she had thought of something, her face was tender and lovely like a flower, with a captivating rosy glow on her cheeks. She knew that her exaggerated figure had great temptation for men, and naturally believed that Mu Xiao, like other normal men, was filled with primitive longing for her plump and seductive body.

  "If it really happened, how would I explain it to my daughter when I see her..." An Rongru thought of her dependent daughter and her emotions gradually subsided, replaced by the worries of a mother.

  Suddenly, footsteps were heard at the door, and An Rongru's just-arisen worries, combined with her shy emotions, made her feel restless for a while.

  Mu Shuo rushed up to the third floor and found An Rongru's room as soon as he opened his spiritual power.

  When the door opened, Mu Xiao saw An Rongru's spirit was not at peace, a pair of beautiful eyes flashing and shrinking, avoiding his gaze, trying not to make eye contact with him.

  I'm not a beast who eats people without spitting out their bones.

  Muxiao looked at her, seemingly unprepared, and self-mockingly said a sentence, but didn't intend to force her. After all, if she wasn't willing, it wouldn't be much fun either. Moreover, since the two hadn't had any relations, Muxiao naturally didn't feel any sense of responsibility or pressure. On the other hand, if An Rongru was his woman, as her man, Muxiao definitely wouldn't casually abandon his own woman.

  An Rongru didn't speak, and Mu Xiao also had an air of "I'll do what I want" about her, not paying much attention to her.

  Muxiao directly put down the backpack in her hand and took out a set of clothes from the daily necessities she had retrieved, then entered the bathroom. Having just tempered her body, Muxiao had sweated profusely and fought for a day, staining herself with a lot of foul-smelling blood, so she naturally wanted to clean up thoroughly.

  Just now when Mu Xiao came in, An Rongru's face was hot and her heart was racing, she didn't know how to react to his gaze. But Mu Xiao didn't say a word, calmly walking into the bathroom, An Rongru's heart became panicked, as if she had made a big mistake.

  "It's come to this."

  An Rong felt ashamed and wronged in her heart, slowly taking off the defensive clothing on her body. But she didn't want to be ignored by Mu Xiao's indifference, preparing to go into the bathroom with Mu Xiao, take a bath together, and even follow the atmosphere to have a relationship.

  Just as she was about to take off her outer shirt, the bathroom door opened again and Mu Xiao stuck his head out, with a tone as usual, instructing: "One of my backpacks has an iron box, inside which are some pieces of meat, you go wash them clean, including the vegetables and meat food you just found back, all washed clean, packed up, and set up the dinner utensils, wait for me to finish washing, then repair some energy stoves, make dinner."

  After finishing speaking, Muxiao shrunk back again.

  An Rongyu was stunned for a long time, suddenly her jade face turned red like a ripe apple, and she found that she had thought too much, he didn't treat her coldly at all.
