The terror receded, and An Rongru's spirit relaxed for a moment. A wave of extreme fatigue surged up, and she went limp in her seat, panting heavily to catch her breath. Sweat poured down like water, soaking her entire body. Her slightly thick and plump lips were tinged with blood, clearly having bitten through them unconsciously as she struggled to hold on earlier.

  He glanced at her and didn't want to give her a psychological shadow for this pressure, so he explained: "Just now facing my pressure, you still feel clear-headed, take the opportunity to experience the existence of spiritual power. As long as you grasp the synchronization of spiritual power with your thoughts, your control will be improved, at least reaching the state of being free and easy. Also, the variant meat you ate for dinner, during your resistance process, gave rise to countless thoughts and emotions, causing your heart rate to accelerate, blood flow naturally accelerated, and the absorption of the rich nutrients from the variant meat also accelerated. Now you should be able to feel that your body no longer has that hot-blooded feeling. As long as you recover your physical strength, tomorrow kill a few more zombies, increase the number of gene resonance times, and your physique may have a breakthrough."

  "I know you're doing it for my own good." An Rongru's tired face broke into a warm smile, clearly feeling her vitality strengthened by several degrees, and her mental strength also became more agile, without the awkwardness of just now. In her heart, she naturally understood that Mu Xiao seemed extreme, but actually had great significance for herself.

  A man who is cool and collected in his actions, but meticulous in his thoughts. His tenderness is hidden behind that cool exterior.

  This is An Rongxu's evaluation of Mu Xiao.

  Although An Rongyu has been working hard to counter Muxiao's pressure, she still hasn't triggered another heteromorphic ability. From start to finish, it was all spiritual power of "Life Detection", constantly shielding Muxiao's pressure and reducing the pressure on her body, but she didn't show a second ability to counterattack.

  That proves her another kind of ability, which is not spiritual system but other systems' ability, and it may appear only under certain circumstances.

  The woodcutter furrowed his brow and thought hard about what kind of ability would have such characteristics.

  "What is gene resonance frequency?"

  Muxiao's words just now piqued An Rongruo's curiosity, and she wasn't quite clear what they meant.

  "You're from a wealthy and noble family, so you must have had contact with people from the military, and probably also know about the Earth Federation's classification of human physical abilities?" Mu Xiao was ready to start explaining from the basics.

  "Uh-huh." An Rongru nodded and said: "C-level is an ordinary person, 3S-level is the strongest person in the world."

  "It was true in the past, but it may not be the case in the future." Mu Xiao explained that the new human body would have several major levels after the "top" level, and each level would have smaller boundaries.

  He didn't want to explain too much about the power of An Ruoyu, only explaining the old human system. SSS-level physique must break through a new level "top" physique, that is considered a true new human. Next, he didn't say much more, turning back to the topic of "genetic resonance".

  "Gene resonance is optimizing the frequency of one's own genetic blood, thereby completing the 'Building Foundation' boundary. This allows for the cultivation of 'Source Power Martial Arts' or 'Soul Secret Methods' to enhance one's combat strength. As long as the boundary continues to be elevated, it can evolve into an eternal, indestructible energy body, coexisting with the universe." Mu Xiao smiled faintly, "In simple terms, it's like becoming a celestial being in stories, creating all things and forming one's own world."

  "Of course, apart from the boundless and infinite possibilities, gene resonance also has many benefits for oneself, such as slowing down aging, prolonging lifespan, optimizing bloodline genes, increasing physical compatibility, and enhancing combat effectiveness."

  "Is that a symbol of eternal beauty?" An Rongru's beautiful eyes sparkled with delight, as if the fatigue on her face had also decreased by several points.

  “……”

  Mushan suddenly ignored the importance of appearance to women.

  "It can be said that way." Mu Xiao said: "You now have fifteen genetic resonances, if your body doesn't have any serious injuries, you'll probably live for another fifteen years, maintain your current appearance for fifteen years, and your blood will start to decline in old age. If you break through to a higher realm, you can even return to your youth."

  "Does one representative mean one year of life?" An Rongruo asked in surprise.

  "Don't think that gene resonance is simple, you'll understand later." Mu Xiao reminded: "At the beginning, one gene resonance represents one more year of life, but as you cultivate to another realm, maybe one realm represents ten years, a hundred years, a thousand years, ten thousand years... As long as the realm reaches a certain level, life is almost eternal, it's just that truly achieving eternal immortality is not a simple matter."

  "It's really far away." An Rongru sighed and then asked: "How did you know that I am now in the 15th genetic resonance?"

  "I can roughly guess a person's evolution degree by observing their blood and breath, combined with the information I get from spiritual detection. Of course, it's not possible for someone to have an evolution degree that is much higher than mine. Actually, you can also detect your own body situation, calm down, sink your spirit into your body, scan 'inner vision' of your blood vessels and genes, feel the frequency of resonance of your blood vessels and genes, this is a kind of information representing one's evolution degree." Mu Xiao had long been able to clearly perceive his own evolution degree with just a thought, after all, he had already gone through one rebirth, no one knew more about the direction of evolution than him.

  "I'll give it a try." An Rongru closed her beautiful eyes and began her first 'meditation'.

  Actually, as long as you repeatedly understand how your body works, in a moment, you can know the frequency of blood vessel gene resonance. After all, this is the movement and quietness of your own body. Once you get used to it, your brain will naturally have feedback information.

  She was a little unfamiliar with the frequency of blood kinship genetic resonance for the first time.

  Taking advantage of this time, Mu Xiao took a bottle of high-proof liquor from the stage, poured all the blood beads harvested today into a plate, washed them with liquor, and then distinguished the quality of the blood beads.

  Blood pearls have a strengthening effect on the physique, but the effect is not great, and only treating injuries and recovering blood gas has a significant effect.

  However, in Muxiao's memory, there are many mature medicine formulas from the future era. As long as precious medicinal materials and a large number of blood pearls are used, the effects of the medicinal materials and blood pearls can be maximized to create extremely rare and precious medicines that are difficult to obtain in the future era.

  So, he didn't use these blood beads for the time being. He would wait until he returned to his residence and moved all the precious medicinal materials stored inside back to the lawyer's building. Then, he would carefully prepare a suitable medicine to maximize the strengthening of his physical body.

  His spiritual power swept away the blood beads' quality, and with a mere thought, he separated the large quantity of blood beads by quality in less than a minute.

  "388 inferior brown Blood Beads, 100 ordinary crimson ones, 78 high-quality deep red ones, and 25 precious purple-red ones... unfortunately, no Blood Crystals..." Mu Xiao muttered to herself as she carefully packed the Blood Beads into different pouches. Just then, An Rongyu also opened her eyes, clearly having gained something.

  "As you said, the bloodline has a subtle vibrational frequency." An Rongru was curious and certain, asking: "I found that in the frequency, there are fifteen identical frequencies of micro-vibrations. After each micro-vibration is completed, the bloodline and genes produce a resonance, and then produce the next micro-vibration. This proves that my evolutionary degree is fifteen times gene resonance, right?"

  "Uh-huh." Mu Xiao nodded and said, "It's like a heartbeat, only the subtle vibration of the resonant frequency is even more delicate. Ordinary people can't even discover their own subtleties, and only we new humans can feel this kind of bloodline genetic resonance frequency."

  "Oh. My evolution degree is fifteen times gene resonance, so what's my physique?" An Rongru asked.

  "You can assess yourself based on your own strength, using the comprehensive value set by the Earth Federation. But in my opinion, your physical strength is only around S-level, although you consumed a lot of variant meat today, so it's possible that you have double S-level physical strength." Mu Xiao said: "Actually, tomorrow when your gene resonance frequency increases, your physical strength should be able to break through double S-level."

  An Rongru, having gone through Mu Shao's terrifying pressure to temper her will, was already very mentally exhausted, but still forced herself to ask: "My new human innate ability, did you discover it just now?"

  She also has an idea of yearning for power.

  Seeing her state of exhaustion, there was a bloody tooth mark on her lower lip. This was an unconscious wound that she had bitten out when she was resisting the pressure. Mu Xiao took out two cups from under the table and also took out a poor-quality blood bead, crushed it into the wine, and gave her half a cup of strong liquor, saying: "You drink a little to boost your spirits, can alleviate your physical fatigue, and your lips are a bit damaged, not very good-looking."

  "Ah." An Rongru lifted her wine cup and took a sip, her face as delicate as jade and radiant as peach blossoms, unusually tender.

  "I didn't find any innate abilities in you, it's possible that you don't belong to the spiritual system..." Mu Xiao paused for a moment, also pouring himself a cup of strong liquor, taking a small sip, with a hint of spicy flavor, said: "It's possible that it's a passive ability from another system, I temporarily can't determine."

  "What's 'passive ability'?" An Rongruo asked in confusion.

  "It's just that without a catalyst, this ability wouldn't be revealed." Mu Xiao replied.

  After chatting for half a cup of wine, An Rongru's spirit improved greatly and her body recovered its strength. However, the fragrance of sweat clung to her outer garment, and her plump figure was clearly outlined in front of Mu Xiao. After discovering this, she felt embarrassed and couldn't continue talking to Mu Xiao, so she hastily went to the bathroom to clean up.

  An Rong's figure was very alluring, but Mu Xiao didn't seem to notice, his mind preoccupied with a guess.

  "She shouldn't have the mysterious ability... This is the potential of having cultivated the 'Soul Secret Method'..."

  He had reason to think so, because only the mysterious system has the most "hidden" nature, and it will not be revealed until the opportunity arises. This is a system full of unknowns, otherwise it would not be called a mysterious system. Moreover, the mysterious system is the most gifted with the secret method of cultivating the soul.

  However, other systems all have some characteristics.

  For example, the "Physical System" has enhanced defenses in close combat, but a beautiful woman like An Rongru is not related to close combat at all. The "Source Power System" is characterized by its most obvious energy attacks, which are very similar to Mu Shuo's mental power, intangible and invisible. However, she cannot hide so deeply, and the abilities of other systems such as "Spiritual System", "Transformation System", "Intelligence System", and "Space System" may be hidden, but it is also impossible for them to remain calm under Mu Shuo's terrifying pressure.

  Of course, the "Intelligence System" is an auxiliary ability and cannot be detected by conventional means. However, those who acquire the "Intelligence System" ability will definitely know what kind of knowledge they have grasped, unlike An Ruxue, who seems to have grasped nothing at all.

  "Space system" also has certain characteristics, at least with an understanding of space and the ability to induce spatial fluctuations. If she had spatial abilities, supporting Mu Shao's pressure would not have been limited to this moment.

  "Mental System" Mu Xiao has "Pure Mental Power" that surpasses even her own, what kind of mental state does she possess and what special abilities does it have. As for the "Change System", it is also one of the most obvious abilities, it's impossible for her to be this system's ability.

  In the end, there was only one "Mystery System" left.
