On the way back to the inn, the Zhang family was not harassed in any way, and returned to their small room with peace of mind.

He was still a little puzzled if the other forces hadn't reacted.

In fact, the news about him had been passed on to the people who were most concerned about this matter as early as when he left Liufu.

"Dry chemical fire extinguishers? The effect is not great, is it only better than a basin of water? When Qin Gongzi got the news, a smile appeared on the corner of his mouth, "Sure enough, it is a lowly inferior world, and in the face of fire, you can only use these useless things." ”

The news that Qin Gongzi got naturally spread to several other sons beside him.

They looked at each other, sighed and shook their heads: "Sure enough, there is no such good thing, the trial of the Fire Cloud Palace did not give people any opportunity to exploit the loopholes." ”

Since Zhang Qing's so-called fire-extinguishing props can only play such a small role, it is better to reserve more ice water in their storage ring to use it.

"When the time comes, let's find some other ways to face the trial."

Several sons said goodbye to each other and quickly left the restaurant.

But Qin Gongzi was still in place, he stopped and looked at the distant direction, which was the location of Zhang Qing's inn.

"How vast is the world, and there are really only those things that resist fire?" A slight smile appeared on the corner of Qin Gongzi's mouth, "Perhaps, you are just throwing stones and asking for directions, wanting to see the status of the fire extinguisher clearly, and then decide whether to use something better?" ”

Beside him, Kuai Yu showed an expression of happiness and shame.

Qin Gongzi's guess Zhang Qing is not clear, but he does have his own plans.

The dry powder fire extinguisher alone is not his real killer feature.

Dry powder fire extinguishers are only used in some businesses to deal with inspections, which are not only polluting, but also not effective in extinguishing fires, which can only block the oxygen supply and avoid re-ignition.

A more effective fire extinguisher is a water-based fire extinguisher, which has low cooling and cleanliness, and can even spray its medicinal agent on itself to defend against flames for a period of time.

However, the price of this thing is very expensive, several times more expensive than dry powder fire extinguishers.

In addition, he can buy asbestos fireproof suits, use gas masks to avoid inhaling harmful substances in burning areas, and carry oxygen cylinders to ensure that he does not suffocate.

In short, he still has a lot of things to face fire, and if the Fire Cloud Cave is really a fiery area, his advantage must be greater.

After all, Huoyun Palace accepted people, and did not explain what model it was collected according to.

Maybe there's a limit to the number of people they can charge? What if he took out all the good stuff in one go, so that others had an advantage to pass the trial?

So in order to make sure he could pass the trial, he had to hide what he could get his hands on and only use the dry powder fire extinguisher as the only prop.

He didn't know if anyone else believed it, but it was really the only way he could do it.

With a little worry, Zhang Qing lay in the room, practicing the self-cultivation method and the Bright Wisdom Sutra.

After a period of pain, he returned to Earth.

At this time, it had not been much time since he left for the high-dimensional world, and noon had not yet arrived.

He also took a shower to wash off the smell of sweat brought by the self-cultivation method, and then went to the subway station.

Zhang Qing was going to Shangdu, changing his appearance with his ever-changing appearance, and buying some fire extinguishers.

Of course, it is still a dry powder fire extinguisher, because he bought too much in ginger copper before, it will definitely arouse suspicion if he buys it again, and even if he uses another identity to pass, he also has a pimple in his heart, and he is worried about revealing the stuffing, so it is better to simply go far away and buy it from Shangdu.

At the same time, it is also because water-based fire extinguishers are not available on Jiang Tong's side.

In other words, not those foam-type water-based fire extinguishers, but real water-based fire extinguishers.

The difference between the two can be searched on the Internet, so you won't talk nonsense anymore.

In short, the latter works better.

The subway station is next to the community, it takes less than 20 minutes to take the subway, you can reach Shangdu, compared to going to the center of Jiangtong city and you have to take a bus for nearly half an hour, Huaqing community here, it can be called the suburbs of Shangdu rather than the suburbs of Jiangtong.

The business capital is a cosmopolitan city, where you can often see a lot of foreigners mixed in, and many of the world's top 100 large groups have branches here.

Therefore, the Shangdu is full of people, and at any subway entrance, you can see dense human heads, as if they are a member of the ant colony, following the people in front of them to move forward.

Walking out of the platform, Zhang Qing couldn't help but stretch out a lazy waist, and came to Shangdu again, which made him suddenly feel a little emotional.

Last time, it was here that he rescued Dou De from two thugs and gained a career as a private school teacher.

It's just that when Zhang Qing walked past another group of patrolling police officers, he suddenly had doubts in his heart.

The number of police officers around him is not too much, he raised his eyes and saw dozens of police officers patrolling the perimeter, which obviously increased the number by two or three times.

It is said that the police force in Shangdu has been insufficient, what happened here that caused so many police officers to arrive?

Before Zhang Qing could react, he heard an angry scolding in the distance, and many police officers immediately rushed towards the scene of the incident.

It wasn't until Zhang Qing also rushed over that he heard that two people were talking to each other because of a collision on the road, and as a result, they scuffled together, and even the police officers who came were punched, and they immediately recruited support and arrested both of them.

There is no way, the two of them are fighting, and they don't listen to the persuasion, and even the police dare to fight, so they will simply arrest them together and calm down.

A police car Ula Ula left, and the people around him made a loud noise, and some newcomers were still inexplicable, and immediately someone told the ins and outs of the matter.

According to the muttering of the people around him, Zhang Qing understood the reason why there were so many police officers here.

Recently, not only are animals furious and like to attack everywhere, but people are also very easy to be irritable, as if a barrel of dynamite can be detonated by a random spark.

In crowded places such as subway stations and train stations, such brawls have been repeatedly prohibited, and there is not only an increasing trend, but also many more cases of evil deeds. As a last resort, the police force can only be sent to prevent such a thing from happening again.

But even with the increase in the number of police officers, such things have not stopped, and they can still be seen from time to time.

Just like today, with a little bit of excitement, it immediately exploded, exhausting these cops.

Zhang Qing understands that this is because of the influence of aura on the human body, so that they will have such an irritable situation if they are slightly stimulated.

It's also a labor pain, after a while...... Maybe I'm used to it.
