When William Clark shouted at the stairway entrance, the two white men immediately turned and ran toward William Clark's position. The one in front was tall and thin, charging forward recklessly, while the one behind was a slightly chubby man. He hesitated for a moment, then actually turned around and tucked the little boy and girl under his arms, one in each.

The two monsters behind them, having found food, stopped chasing, which allowed the first man to reach the stairway. When the tall, thin man saw the pistol in William Clark's hand, he immediately shouted, "Dude, run!

All the guns are completely useless!!"

As he spoke, the tall, thin man dashed past William Clark and ran upstairs.

Meanwhile, the slightly chubby man, still carrying the two children, came running into the hallway, panting heavily. At this moment, one of the two monsters that had chased into the building actually abandoned the bloody, shredded flesh it was gnawing on and turned to charge at the chubby man. The chubby man also heard the monster chasing behind him and began to shout loudly, tears and snot streaming down his face, but even then, he still didn't let go of the two children.

William Clark was also extremely tense. He aimed his pistol at the oncoming human-faced dog. The monster was now less than ten meters away from him, while the chubby man was about seven or eight meters away. The monster could pounce on the chubby man at any moment. At that critical instant, William Clark pulled the trigger.

In his heart, he was already prepared for the bullets to be useless, but the moment he pulled the trigger, he saw that what came out of the pistol's muzzle was not a spark or a flash, but a ball of white light. It wasn't like a laser—its speed wasn't quite that fast—but more like a glowing orb. Although it was still extremely fast, the naked eye could just barely make out a blurry trajectory.

The glowing orb shot straight out from the muzzle and, in a flash, struck the human-faced dog's chest. With a crackling explosion like thunder, the monster's chest was blasted open with a hole the size of a basketball, so large you could see right through to the other side.

The chubby man was completely stunned. He stared blankly at William Clark, then looked back at the human-faced dog monster.

It wasn't just the chubby man—the tall, thin man running up the stairs was also stunned, and even William Clark himself was shocked. The power of this pistol was as exaggerated as carrying a cannon. These weren't bullets anymore; anyone would believe it if you said it was ball lightning.

But William Clark quickly put away his look of surprise and shouted loudly to the chubby man, "Hurry up and get over here!"

Only then did the chubby man snap out of it, stumbling over to stand behind William Clark, then putting down the two children and gasping for breath. At this moment, the tall, thin man actually stopped running upstairs, but he didn't come down either. Instead, he shouted from the middle of the stairwell, "That's a pistol!? Is that really a pistol? Are there any more bullets? Dude, do you have any more bullets?"

William Clark didn't answer, but kept a close eye on the other monster in the distance. At the same time, he saw that the monster he had just killed was indeed starting to emit white glowing particles. The vast majority—at least ninety percent—of the white glowing particles dissipated into the air, but about ten percent drifted toward William Clark and landed on his skin, seemingly merging into his body.

This time, William Clark clearly saw the process of these white glowing particles merging into his body, and he became even more certain that his soul had grown stronger because of them.

He just didn't know why only ten percent were absorbed by him. Was it because the distance was too great, or because he didn't try to catch them, or was there some strange rule that only allowed him to absorb a tenth?

And moreover...

William Clark looked at the chubby man behind him, the two terrified children, and the tall, thin man peering from the stairwell. They all seemed completely oblivious to the white glowing particles. Was this something only he could see and absorb?

William Clark had too many questions in his heart, but now was clearly not the time to dwell on them. He had just shot and killed a monster, which immediately enraged the other one. That monster abandoned the flesh it was gnawing on

and began to charge at William Clark in a frenzy.

At once, William Clark aimed the pistol's sights. After all, he was someone from a peaceful world, so when the monster was still at least twenty meters away, he pulled the trigger. Once again, a white glowing orb shot out, but this time it hit the wall beside the monster, blasting a huge hole in it. Dust billowed up, and the monster burst out of the cloud, moving fast and with great strength. Amidst the flying debris, the monster was now only about ten meters from William Clark.

"Hit!"

William Clark grew even more anxious. In his panic, he pulled the trigger twice in quick succession. Two white glowing orbs shot out one after the other—one hit the monster's left arm, the other struck beside its head. This finally managed to hit the monster: its shoulder was completely shattered, and most of its head was sliced off. At last, the monster crashed to the ground, sliding several meters, coming to a stop almost right at William Clark's feet.
