Poison Gas

What can incapacitate someone without killing them?

The answer is simple: poison.

In this world, poisons are basically made from various herbs.

As long as the poison's formula is deciphered, an antidote can be developed.

However, for Gu Qi, none of this was a problem. He was preparing to create chemical poison gas.

For instance, Mustard Gas, which affects the skin, eyes, and respiratory tract, would be excellent.

Inhaling a small amount of Mustard Gas can lead to symptoms such as general discomfort, vomiting, depression, drowsiness, central nervous system inhibition, and parasympathetic nerve stimulation.

Severe poisoning can even lead to death.

Most importantly, there is no specific antidote for Mustard Gas.

But for Gu Qi, this wasn't an issue.

After all, he had the Secret Brew, and as long as he kept the dosage small when administering it, there wouldn't be any major problems.

Preparing Mustard Gas was a bit troublesome, but fortunately, the laboratory had sufficient facilities and materials for him to use.

Without further ado, Gu Qi didn't bother going to a laboratory in another dimension. Instead, he started working directly in his underground laboratory.

Not daring to make too much, Gu Qi only produced about a thousand milligrams of liquid Mustard Gas before starting to use it to create traps.

Once finished, Gu Qi immediately left the laboratory building.

The tree stumps were already in place. Now, all he had to do was wait for some unlucky rabbit to stumble into them.

The next morning, after checking the traps, Gu Qi headed towards the Inuzuka Clan with three foolish Ninja Dogs.

Gu Qi had realized that these three Ninja Dogs had been getting out of hand lately, practically running wild.

If they continued to be neglected like this, these guys would likely become useless.

Therefore, this time, he was determined to have the Inuzuka Clan give these guys some serious training, at the very least so they could bark when someone invaded.

This was only part of the reason. The more important point was that Gu Qi wanted to protect them.

What if, after the traps were activated, the three Ninja Dogs accidentally ran into them? That could be disastrous.

"Don't worry, Gu Qi-kun. In three days, I'll make sure those three undergo a complete transformation," Hana Inuzuka said, patting her heaving chest after receiving Gu Qi's payment.

Gu Qi glanced at the three trembling little guys and said, "Train them hard. It's okay even if they get injured."

Hearing Gu Qi's words, the three Ninja Dogs became even more scared.

"Don't worry, I'll take good care of them."

Gu Qi nodded, then said to Hachi and the others, "Be good and listen. I'll pick you up in three days."

As soon as he finished speaking, Gu Qi, with a look of deep resentment from the three Ninja Dogs, firmly abandoned the three foolish dogs.

Gu Qi spent most of the day outside.

Either he was training, guiding Naruto, or just exploring and eating.

In short, it wasn't until evening that Gu Qi returned home.

Upon returning home, after putting on the protective suit and mask he had prepared beforehand, Gu Qi leisurely walked to the entrance of the laboratory building.

As soon as he opened the door, a figure lunged towards him.

Easily dodging to the side, he heard a thump, and the person fell in front of him.

After checking that the person was still breathing, Gu Qi picked them up and threw them into the courtyard.

Continuing into the laboratory building, as he had expected, many people were lying inside.

After carrying them all out to the courtyard, Gu Qi examined each of them.

If he found anyone in serious condition, Gu Qi would casually inject them with some Secret Brew.

Who said alcohol had to be drunk? Gu Qi found that directly injecting the Secret Brew was much more effective than drinking it.

After examining them one by one, Gu Qi discovered at least three groups of people.

Anbu, Root members, and some unknown Konoha ninjas.

As for how Gu Qi could distinguish between Anbu and Root members, it was simple: the masks.

Anbu masks were generally animal masks, while Root masks were more varied.

Among these people, Anbu and Root members constituted the majority, with only two other ninjas.

Regarding these two unknown ninjas, Gu Qi guessed they were likely pawns left behind by Orochimaru in Konoha.

"Now that the actors here are in place, it's time to notify others to join the stage."

As Gu Qi spoke, he silently took out a special shell for a Railgun.

Unlike other shells, this one didn't have a common trigger fuse. Instead, it had a time-delay fuse designed by Gu Qi.

This shell would activate once it received power, so it would be immediately activated upon passing through the electromagnetic coil.

Once activated, it would detonate the explosives inside the shell after a set time, thus **the shell.

Gu Qi slowly extended his right hand towards the sky, coolly launching the shell into the air.

Boom~

An explosion rang out, disturbing countless people from their sweet dreams.

"Gu Qi, what's going on? What did you do?"

When Kakashi arrived at Gu Qi's courtyard following the sound, he saw Gu Qi surrounded by Anbu and Root members and couldn't help but ask.

Gu Qi shrugged his shoulders. "I didn't do anything. I just don't know how these people suddenly appeared in my lab. I was afraid they had accomplices, so I fired a signal to ask for help."

Kakashi's eyelids twitched. He understood that Gu Qi was doing this on purpose.

It was highly possible that these unconscious Anbu members were all Gu Qi's doing.

However, there were too many eyes and ears here. Kakashi raised an eyebrow at Gu Qi and said no more.

"Looks like the old man is going to have a headache," Asuma muttered to himself with a slight smile, hidden behind the onlookers.

"Kakashi Gu Qi, the Anbu were pursuing several foreign spies. We apologize for the intrusion into your laboratory."

Just as the crowd of onlookers grew, an Anbu captain suddenly appeared before Gu Qi.

Shrugging, Gu Qi said indifferently, "It's fine! It's fine! Since you were on a mission, these things aren't a problem."

"Thank you. Take them away," the Anbu captain nodded at Gu Qi, then directly ordered the Anbu and Root members around him to escort the people in the courtyard away.

Seeing that there was no more entertainment, the other ninjas also left one by one.

Only Kakashi's close friends, like Kakashi himself, remained.

"You all should go back," Kakashi said, nodding slightly when he saw Might Guy and the others hadn't left.

"Is it really okay? The old man can be quite vengeful sometimes," Asuma said, biting on his cigarette.

Kakashi shook his head and pointed at Gu Qi, who looked harmless. "Since this guy isn't nervous, it means everything is under control. Don't worry, it'll be fine."

"Alright then. Just let me know if you need anything."

Since Kakashi had said so, Asuma nodded and left.

Although Might Guy and the others didn't say anything, their gazes before they left conveyed everything.

After everyone had left, Kakashi turned his attention to Gu Qi.
