Dan closed his eyes calmly, sitting cross-legged at the very bottom of a deep trench, five hundred meters beneath the water's surface. At this depth, he no longer felt the crushing, immense pressure that would have pulverized a normal man; it didn't affect him even slightly anymore. His enhanced body endured the weight as if it were a gentle breeze; in fact, he felt complete comfort at this depth, capable of training and meditating for long hours without any localized discomfort or physical fatigue.
First, Dan noticed something truly amazing and vital: he could now hold his breath underwater for much longer than ever before. After testing his limits, he discovered he could remain submerged without breathing for four continuous hours. This was a staggering improvement compared to the mere hour and a half he was capable of before applying the enhanced seal at this level of pressure. This massive leap was a natural and logical result of his lungs, heart, and entire respiratory and circulatory systems improving significantly thanks to the new seal. His internal organs had become many times more efficient at utilizing oxygen, storing it, and distributing it to his cells. Furthermore, Dan was fully confident that as time passed and the Vitality Seal continued its permanent work, this duration would increase even more, perhaps reaching six or seven hours in the future, giving him a legendary advantage.
The second important thing he clearly noticed in the short period since applying the enhanced seal was that he no longer needed much sleep. His requirement for rest had dropped drastically and shockingly. He discovered that sleeping for only two hours every three full days was entirely sufficient to restore his full activity, energy, and mental focus. He felt no tiredness or exhaustion whatsoever despite this lack of sleep. Naturally, for Dan—who was obsessed with training and continuous self-improvement, and who viewed time as his most precious resource—this was excellent news. He would no longer have to waste valuable time sleeping for long hours every day; instead, he could focus on training, research, and development for much longer periods. If a day consists of twenty-four hours and an average person sleeps eight of them, a third of their life is lost; but Dan would only lose a tiny fraction, giving him a massive advantage in time management.
Additionally, he began to feel clearly that his expected lifespan was stretching continuously, gradually increasing from the three hundred and fifty years he possessed before the new seal. He felt vitality in every single cell of his body. Based on his observations of the changes occurring within him, Dan felt great confidence that once the enhanced Vitality Seal reached its maximum effectiveness—which would happen gradually over the coming years—his projected lifespan would reach approximately seven hundred full years. This figure was surprising even to Dan himself, as he had previously expected the seal to extend his life to only five hundred years. It seemed the cumulative improvements of each internal organ were much stronger than he had calculated. Seven hundred years is a long time by any standard, especially when compared to Dan's current age, which has not yet even reached a century. His true age was currently only 75 years since he was born in his original world, meaning he was still at the very beginning of a very long life.
By the standards of this harsh and dangerous world, 75 years is considered very old and rare, as the average lifespan for ordinary people in this era did not exceed thirty years due to wars, diseases, famines, and the brutal lifestyle. But Dan had achieved the impossible. Even his external appearance did not reflect his real age at all; he looked like a young man in his early twenties, with a fresh face, healthy skin without wrinkles, toned muscles, and long hair.
Another important observation was that the more he ate, the faster and more effective the Vitality Seal became. The seal converted nutrients from food to improve the body with incredible efficiency. Consequently, in the short period following the new application, he entered a massive wave of continuous and intensive eating. He devoured enormous quantities of meat, which led to a significant consumption of the livestock the family raised. His twelve wives and eldest daughters entered a similar wave of non-stop cooking, working day and night to feed the always-hungry Dan. It was a staggering sight for everyone to see the sheer volume of food he consumed.
However, after a short while, he wisely slowed the pace of this eating frenzy. He realized that such a high rate of meat consumption would cause noticeable damage to the flocks of sheep, cows, and chickens the family had carefully raised for years. This depletion could negatively affect the rest of his large family, as the number of his children had now reached forty-four, excluding his twelve wives. Almost all of them had large appetites—especially for meat—which, while not as insane as Dan's, were still large compared to normal humans. Therefore, Dan issued a clear and direct order to his eldest sons to focus their efforts on improving livestock management and increasing the numbers to ensure sufficient food supplies for the growing family.
As the best and most practical solution for now, Dan began going on regular daily hunting trips into the forests and mountains surrounding his base. He hunted large game himself, such as deer and massive elk, to satisfy his unquenchable stomach. This method served two important goals: first, satisfying his hunger without harming the family's herds; and second, it served as a form of enjoyable physical training. Hunting required movement, speed, and precision, and Dan enjoyed it thoroughly. He sat that night after a successful hunt, watching a buffalo roasting before him over a warm fire, gazing at the star-filled sky and enjoying the beautiful, quiet moment provided by the wilderness around him.
