When the competition reached halfway, those ordinary soldiers were no longer in sight as most had stopped around the 25-kilometer mark, gasping for breath! They basically couldn't run any further. A marathon is different from explosive sprinting; maintaining a steady pace allows for adjusted breathing, making it a sustainable exercise! Whereas explosive running, every step depletes your strength! Around the 25-kilometer mark, many had reached their limits, the speed was shockingly fast, hardly anyone ran less than half an hour for 25 kilometers! However, Zhang Dabiao's group had already broken through the 25-kilometer milestone in about fifteen minutes and was heading towards fifty kilometers! While most of the ordinary soldiers had fallen, there were still a few who were silently gritting their teeth and persevering! For example, Heizi; don't be fooled by his thin, short stature and dark appearance! But the hidden strength within him was indeed a bit terrifying, this guy ran fast, incredibly fast! Though compared to Zhang Dabiao's group he was inferior, what was unexpected was that when Zhang Dabiao's group broke the 25-kilometer mark and began heading for fifty kilometers, Heizi still hadn't given up, stubbornly trailing behind, about ten kilometers behind, which made Jiang Cheng conclude that if the Genetic Evolution Potion was used on him, his physical quality might improve, potentially even more fiercely than Zhang Dabiao! They were indeed freaks, Jiang Cheng suddenly realized using such potions on soldiers was indeed a very correct decision! After all, if these were sold, it would only be a waste on ordinary people, precisely how much could the affluent truly improve their bodily foundation? Especially those wealthy people with bulging bellies, each very wealthy, looking glossy and well-fed, but one point! Because they lack much muscle, these Genetic Enhancement Potions can improve their physical quality, but one shouldn't dream of explosively multiplying their strength, that's entirely unrealistic! But for these soldiers, everything's different! Finally, Zhang Dabiao and the others almost effortlessly reached the finish, each looking rather composed, just slightly flushed with a touch of rapid breathing! But at least none of them could be felt to have noticeable fatigue, and another big surprise was when they rested for about twenty minutes at the end, they suddenly saw Heizi? Panting heavily, running over with a brilliantly radiant smile, though his face was pale as paper, looking like he might collapse at any moment! "Heizi, Heizi, how did you do it?" Zhang Dabiao and several others hurriedly went over to support Heizi, showing concern, asking hastily! After coughing heavily, Heizi clearly had exhausted all his strength to run here! My, my god... you all, those guys really run way too fast. Even I couldn't catch up, I'm completely convinced now, this Genetic Enhancement Potion is really impressive!" Heizi, out of breath and weak, finally managed to express his thoughts! No, no, no, you are the strongest, we are only able to reach such speeds thanks to the Genetic Evolution Potion, but you managed to chase us with your inherent physical quality, showing that among all the ordinary soldiers, you are the most remarkable one! Jiang Cheng laughed as he spoke; he originally thought Zhang Dabiao's physical quality had reached a limit. It was astonishing for Huaxia's soldiers to be strengthened to this degree, but he didn't expect Heizi to offer an even bigger surprise. This is the true monster, born destined to be a soldier! It was quite regrettable that the Genetic Evolution Potion wasn't used on him last time! Just then, Director Zhang's group slowly arrived at the scene by car, not because they couldn't catch up with Zhang Dabiao's team, but because they stopped halfway to check on the conditions of the soldiers! Goodness, each one was exhausted, lying on the road resting! After checking everyone's condition, they finally got into the car, leisurely arriving at the finish line, and as expected, they saw Zhang Dabiao and his team waiting on site! But what made them incredulous was these few people showed no signs of fatigue whatsoever; it was as if they hadn't just completed a fifty-kilometer run—it was quite impressive! "Big Biao, you guys are alright?" Director Zhang, a bit concerned, came over to ask again! But Zhang Dabiao and a few others didn't think something was wrong, just felt their breathing was slightly more rapid than before, but physically they showed no signs of exhaustion! Tʜe source of this ᴄontent ɪs 𝓷𝓸𝓿𝓮𝓵·𝕗𝕚𝕣𝕖·𝙣𝙚𝙩 Even their muscles felt warm and cozy, as if running was a very enjoyable activity for them! Not surprising, since they had just undergone enhancement from the Genetic Evolution Potion, their muscle levels had reached a frightening degree, but due to resting days they hadn't trained the newly developed strong muscles! This high-intensity run felt immensely comfortable, akin to returning from a sauna! Feeling an endless reserve of strength, and consciousness was exceptionally clear! Report, sir, we are fine, but Heizi really needs some good rest, he just ran fifty kilometers nonstop, an unbearable burden for any normal person!" Before Zhang Dabiao could finish his sentence, Heizi suddenly spewed a mouthful of blood on the ground! At that moment the military doctor rushed over to check him, after examination, he said gravely: "This guy exerted himself too much, and the fifty-kilometer bumpy run might have caused some internal organs to rupture, which is troublesome, if it's internal bleeding, there's almost no chance of treatment! "What? How could this be, he just seemed fine!?" Zhang Dabiao and the others panicked at that moment, no one expected such an outcome, spare no effort to save Hai!" Director Zhang issued an imperative order, Heizi was different from other soldiers, he was an only child!
