Those who reincarnate must die.

Matsumoto Fumino stood in front of the group of hackers, raised his hand to form a hand seal, and summoned a semi-transparent vengeful spirit.

People with a perception level below 50 cannot see such vengeful spirits at all; they only feel that the temperature in the room has suddenly dropped significantly, and they feel a chill for no reason.

Matsumoto Fumio, summoning the vengeful spirit, arrived before the first hacker. The hacker suddenly shuddered, looking at the petite girl before him, somewhat curious about what he was afraid of.

Suddenly, with a flick of his finger, the vengeful spirit darted into the hacker's body. The hacker convulsed instantly, and after a few seconds, the vengeful spirit emerged, leaving the hacker collapsed to the ground, foaming at the mouth.

"It wasn't him." Matsumoto Fumino shook her head.

She had just allowed a vengeful spirit to possess the other person's body. If the other person's soul was strong enough, it would resist the vengeful spirit's invasion. Given the vengeful spirit's status, even ordinary sacrifices would be unable to resist it without some kind of soul enhancement, let alone ordinary people.

The price is that after being briefly occupied, the hacker will temporarily fall into dementia and will need at least ten days to half a month to recover.

Using this method, Matsumoto tried it on one by one, and soon half of the hackers collapsed to the ground, foaming at the mouth and convulsing.

The eighteenth person arrived, and Matsumoto, as usual, commanded the vengeful spirit to enter his body, causing the hacker to convulse. But after a few seconds, the vengeful spirit didn't withdraw, and the hacker's convulsions stopped!

"How could this be?" Matsumoto Fumino was taken aback. "Your spirit has been imprisoned?"

Before he could finish speaking, the hacker suddenly pulled out a knife and stabbed it into his own throat!

But the knife stopped just centimeters from his throat.

Zhang Lang appeared beside the hacker without anyone noticing, and with his gloved right hand, he grabbed the hacker's wrist.

"Is it him?" Zhang Lang turned to ask Matsumoto Fumino.

"He is indeed acting strangely, but something feels off..." Matsumoto Fumino was trying to communicate with the vengeful spirit: "This person's soul isn't powerful, but there's some kind of strange power within him that has imprisoned my vengeful spirit... No, not imprisoned, but merged. He has merged the vengeful spirit with his own soul, and the vengeful spirit can no longer leave this body. Even if I kill this person, the vengeful spirit will dissipate..."

"They've been given troublesome abilities..." Zhang Lang looked at the remaining people: "So, the real culprit is among the remaining fourteen?"

"Matsumoto, are there any other vengeful spirits?"

"I do have some... but the others don't have this one's insight and might be fooled by powerful soul skills." Matsumoto Fumino looked at the bewitched hacker with heartache in her eyes.

Zhang Lang could purify all the abnormal power within this hacker, but in doing so, Matsumoto's vengeful spirit would also dissipate.

"There are still fourteen people left, let's just kill them all," the governor suggested, causing the remaining hackers to tremble.

"The key isn't these fourteen people," Zhang Lang said through gritted teeth. "The real threat is these fourteen people who have been in contact with us during this period. They could all become carriers of the intelligent virus, potentially affecting tens of thousands of people."

"Do you still have screening methods?" The governor frowned. "The Mechanical Empire has been destroyed. The remnants of mechanical civilization must be wiped out. As long as the continuation of humanity can be guaranteed, any sacrifice is worthwhile!"

Zhang Lang looked at the governor, and the look in his eyes made the ruler of Iron City break out in a cold sweat and take two steps back.

At this moment, Le Xinyi stepped forward: "I do have a solution."

"I am proficient in a type of hypnosis. Once someone is hypnotized, I can directly issue commands to them through my mind. If someone has been possessed, their mind is strong, and they will not be so easily hypnotized by me and will not be able to receive my commands."

"Then, by observing who doesn't react, or whose actions are inconsistent with my commands, we can determine who's the problem!"

"Great idea!" Lu Ren clapped his hands and said, "Let's try it!"

Le Xinyi nodded and immediately cast a spell, establishing a mental connection with everyone. Soon, everyone's eyes became glazed over. But everyone knew that someone was definitely acting.

Le Xinyi ignored all that and directly gave them instructions.

Then, a magical thing happened.

Of these fourteen people, some took three steps forward, some lay down directly, some jumped twice in place, some spun around... In short, everyone's actions were different.

"What's going on?" Just as everyone was wondering, Yue Xinyi suddenly pointed to two of them: "It's those two!"

Everyone looked and realized that only these two people were doing the same thing: raising their hands high.

The moment Yue Xinyi pointed them out, the two tried to resist, but no matter how fast they were, they couldn't outrun Zhang Lang's explosive force.

As an invisible force enveloped them, the two were instantly subdued.

"What's going on?" The others looked at Yue Xinyi curiously. "Didn't you say there was a problem if the movements were different? Everyone's are different, so why is there a problem with only two who are the same?"

Le Xinyi laughed and said, "Because I was lying to them. I didn't hypnotize them at all... My hypnosis skills are probably easy to crack. Even if they aren't hypnotized, they can still receive my instructions and follow them. They won't be able to tell the difference and will be fooled."

"So I simply established a mental connection with them and issued the same commands."

"You issued the same command?" Ye Peng asked curiously, "Then why are everyone's actions different?"

Le Xinyi smiled slyly, "Because in the command I issued, I encrypted and incorporated a piece of information related to the altar."

"That message and command were intertwined. Although it sounded like an ordinary command, if you listened carefully, you would receive information related to the altar... Although most people are unaware of this message and have no ability to decipher it, it is objectively true that they have glimpsed the secret of the altar."

"So..." Thunder's camera flashed red, "So the altar distorted that information, and indirectly distorted your orders!"

Le Xinyi smiled and nodded: "That's right, so ordinary people can't receive the correct instructions at all, and will make all sorts of messy movements according to the distorted instructions. Only heroes from the altar can accurately perform the actions I specify."

As she spoke, Le Xinyi looked at the two controlled hackers: "For example, raise your hands!"

"Impressive!" Zhang Lang nodded in admiration, then with a wave of his hand, dragged the two men in front of the governor.

"Alright, now it's your job. Check all their activity records in Iron City during this period, and find everyone they've come into contact with, whether in person or by exchanging information online."

"Don't let a single one escape!"
