High Martial Arts: Gains one point of health per second, sweeping across the heavens.

Su Jie quickly went out, first to retrieve the button-sized signal transmitter and clip it to his collar, then, following the navigation, he found the nearest mission entrance—a sewer maintenance port located deep in an old neighborhood.

Unscrewing the heavy cast iron manhole cover, a strange stench, a mixture of musty and fishy smells, hit me. The passage below was pitch black, with only the faint sound of water.

Su Jie frowned, but without hesitation, he turned on the flashlight function of his bracelet and jumped down.

The well was a spacious circular passageway, wide enough for two people to walk side by side. Underfoot was ankle-deep sewage, with concrete platforms on either side for walking. The air was humid and stifling; beams of light from the lamps painted limited areas in the darkness, beyond which lay profound darkness. Occasionally, rustling sounds drifted through the air, sending chills down one's spine.

Su Jie held his breath, pushing his senses to the limit. The nearly 700 points of combat power brought not only strength, but also vision, hearing, and smell far exceeding those of ordinary people. He could clearly hear the faint sounds of things being gnawed in the distance, and smell the unique pungent odor of rodents in the air.

He cautiously walked deeper into the passage.

After walking for about five or six minutes, at the corner ahead, a dozen pairs of scarlet lights suddenly appeared in the darkness!

"Squeak—!"

A piercing scream rang out, and a dozen mutated rats, the size of domestic cats, with glossy fur and sharp teeth, surged out from around the corner like a black tide. Their scarlet eyes gleamed with bloodlust as they pounced on Su Jie! They were incredibly fast, darting across the slippery walls and platforms, leaving behind gusts of foul wind.

If an ordinary martial artist with a combat strength of fifty or sixty were suddenly surrounded by so many mutated rats, they would probably be caught off guard and die on the spot.

But Su Jie's pupils only contracted slightly; he felt little fear, but rather a surge of excitement and anticipation.

"Well done!"

He let out a low shout, neither dodging nor avoiding, and without even using any fancy martial arts techniques, he simply threw out a punch!

boom!

The air seemed to explode from that punch, producing a muffled sonic boom! A surge of immense blood and qi erupted from the fist, creating an invisible shockwave!

The first three or four mutated rats were hit as if by a speeding car, and before they could even scream, they were blown into clouds of blood mist! The mutated rats behind them were also thrown out by the powerful shockwave and crashed into the hard concrete wall, their bones broken and their tendons snapped, clearly beyond saving.

The power of one punch is so terrifying!

Su Jie himself was stunned for a moment, looking at his fist and feeling the destructive power that far exceeded his expectations. "Is this the pure power of nearly 700 combat points? Truly terrifying!"

The signal transmitter on his collar vibrated slightly, and the number displayed on it jumped, increasing the number of kills he had just made.

"But the efficiency is still too low. How many are killed with one punch?" Su Jie shook his head, dissatisfied with the cleanup speed. He glanced at the scattered rat carcasses on the ground, then tried to go forward and tear off a few pieces of the relatively intact fur with his bare hands, stuffing them into the bag he carried. "I wonder how much this material can sell for. Every little bit helps."

While directing his Qi and blood to temper his martial acupoints, Su Jie continued to delve deeper. The subsequent cleanup work became simple and tedious. He began to consciously hone his combat skills, engaging in close-quarters combat. Whether with fingers, palms, or fists, he often struck the mutated rats' vital points precisely just as they pounced.

One fatal blow!

His movements, initially slightly clumsy, quickly became fluid and efficient. Su Jie advanced steadily through the dark sewers, leaving behind only a trail of rat carcasses in his wake.

Occasionally, you might encounter one or two rat kings that are noticeably larger, with shinier fur and a stronger aura. They are faster, have sharper claws and teeth, and even know simple pouncing techniques.

But in the face of such an absolute difference in strength, all of this was in vain. Su Jie didn't need to exert any extra effort to easily deal with them and skillfully dug out the rice-grain-sized crystal cores containing faint blood energy from their foreheads.

In just two hours, Su Jie cleared the first area assigned to the anonymous identity "Shadow." The signal transmitter recorded an astonishing 127 kills, including three Rat Kings.

"That's about enough, time to go up and redeem the rewards." Su Jie looked at the bulging bag of materials and nodded in satisfaction.

Two days ago, he was just a penniless transmigrator, but now he has mastered the skills of selling blood and playing whack-a-mole, which is enough to ensure that he will not go hungry!

As he climbed out of the sewer, looking somewhat disheveled and carrying his bag, the sunlight outside was blinding. He took a deep breath of fresh air, feeling as if he had stepped into another world.

Head directly to the mission settlement point designated by the City Hall.

When the staff saw the kill logs and materials submitted by Su Jie, especially the three Rat King crystal cores, they were visibly taken aback and glanced at Su Jie a few more times. This young man wearing a mask looked ordinary, and his aura didn't seem particularly strong, yet he was so efficient?

「匿名代号『影』，确认击杀普通变异鼠127只，鼠王3只。奖励结算：127*500 + 3*5000 = 78500星元。材料回收，作价4200星元。总计82700星元。是否确认转入您的匿名帐户？」工作人员例行公事地确认。

"Confirmed," Su Jie replied calmly.

The bracelet vibrated, and the balance instantly jumped from over 7,000 to 90,000 Star Coins!

A huge sum of money has been acquired!

Most importantly, through these two hours of "practical instruction" with the mouse, his control over his own strength has reached a new level. Although he is still far from being able to control his own body perfectly, at least he is no longer the "nouveau riche" with only brute force.

After leaving the settlement point, Su Jie went to a high-end restaurant and treated himself to a meal. He ate a set meal of ferocious beast meat worth tens of thousands of star coins, and felt that his blood and energy were much more active.

It was already afternoon when he returned to his rented room. After asking his homeroom teacher for leave on Monday, Su Jie didn't rest and instead lay down on the bed again to immerse himself in the great task of tempering his martial arts acupoints.

With ample funds and food supplies, he could focus on improving his strength for the remaining two days without any distractions.

……

Time flew by, and on the second and third days, Su Jie's life became extremely regular. During the day, he spent a small amount of time taking on sewer unclogging tasks and continuing to familiarize himself with his surging power through friendly interactions with the rats. At night, he would stay up all night refining his martial arts skills.

His combat skills improved rapidly through repeated battles with mutated rats, and his control over his strength became increasingly refined.

And his combat power skyrocketed!
