According to some information learned from the security department, it is not an overtly visible organization that is eyeing him, but a deeply hidden secret organization.

Specializing in some illegal activities such as smuggling, drug trafficking and even human trafficking, it has also been jointly eradicated by various governments several times, but it has always revived, especially since Bitcoin can be circulated, and the cleanup of the secret organization has become much more troublesome.

It's just that Zhang Tiancheng can't figure out whether this group of guys has water in their brains, how can they want the faster-than-light communication chip technology, which is unlikely to produce any benefits in the foreseeable next few decades.

Although I can't figure it out, I can't be wrong with the feeling of being targeted, but there are more people on the street, and it's hard to find out who is quietly observing you.

In fact, with the means at my disposal, of course, there are many ways to deal with these ill-intentioned people, but I don't want to do it for the time being.

After thinking about it slightly, I finally took out my mobile phone and sent a message to a phone number I got from the security department, as for whether the other party can solve the problem, I don't know for the time being, if it can't be solved, it's not too late to do it yourself.

After sending the message, he continued to shop for a while, but he had completely lost the interest just now, and when Xiao En took his hand and walked towards a crowded place, he casually pulled the person back.

“…… What's wrong? Xiao En, who was pulled by Zhang Tiancheng, was also a little inexplicable.

"Xiao En, it's not too early, otherwise we'd better go back!"

"No, it's only eight o'clock, and my brother usually doesn't sleep at twelve o'clock in the middle of the night."

"Well, I feel very sleepy today, otherwise I will take you to Huaguo and go to some super night markets during the next long vacation, and I will accompany you as long as you want to buy as many things as you want?"

"It's going to be a long vacation, can we go shopping for a while?"

"Xiao En, why haven't we seen each other for more than half a month, let's go back early and study each other's human bodies." hugged someone and leaned into Xiao En's ear and said a word, the little girl was a little embarrassed, and punched Zhang Tiancheng, but she was instantly persuaded by Zhang Tiancheng.

"But after all, next time you take me to the super night market, you can't forget it."

"That's a must, when the time comes, you can buy whatever you want, brother, I'm not short of money."

“…… Actually, I want to go home early, and I've dreamed of you at night several times these days. He said a little shyly, and then took Zhang Tiancheng's hand and happily walked towards the car in the distance.

It is said that Zhang Tiancheng suddenly left with Xiao En, and also exposed the target of several people who were hiding and observing, because Zhang Tiancheng left the night market here, and those people also moved, although they avoided the sight, they couldn't imagine that Zhang Tiancheng still had the function of scanning the surroundings with divine sense, so the sneaky appearance was suddenly discovered by Zhang Tiancheng.

Although I didn't want to do it, it's just that these guys still want to keep up quietly, of course, this can't be left alone.

The divine sense quickly glanced at the surrounding situation, and everything within a radius of ninety meters could be seen clearly, and he unexpectedly found that there was a big hornet's nest on a big tree dozens of meters away, and he suddenly had an idea.

……

A sudden breeze unexpectedly rolled up a broken ancient branch, which happened to stab the hornet's nest, and then the hornet's nest fell from the tree, and was blown by the wind and accidentally hit several people's heads.

Then a swarm of wasps swarmed out, recognized that the men had smashed their nests, and then slammed into them, and in an instant there was a howl like killing pigs, and at the same time a commotion in the lively night market.

And Zhang Tiancheng also over-controls an ultra-micro spatial positioning device the size of a sesame seed, which is one of the many devices prepared for the next mission world, which is a combination of magic and technology, and its main function is spatial positioning, with quite high accuracy.

Although I don't want to do anything to that mysterious organization for the time being, it is necessary to leave a little bit first, and if you dare to entangle, you don't mind completely ending the thief's den of that secret organization.

At a speed of nearly 100 meters, he took advantage of the chaos to break into a person's skin, and because he was pricked by a wasp, he didn't even notice that he had been silently and wonderfully implanted with a microchip.

The sudden change in the night market was also secretly glad that Xiao En was fortunate to have listened to Brother Zhang's words just now, otherwise maybe he would have been stung by a wasp among the people.

Looking at the few people who were running around with wasps from afar, I felt scared when I imagined it, not to mention that I suddenly remembered my brother Zhang's ability.

"Brother Zhang, your ability is so great, why don't you help those people?" Xiao En asked a little puzzled.

"Dear, all this is the arrangement of fate, when it is not necessary, I dare not interfere too much." Zhang Tiancheng said nonsense.

"Then if I get stung by a wasp, won't my brother help me?"

"Stupid, I still have to ask about this kind of thing."

"People are just curious, if I get in trouble, my brother will definitely help me, right?"

"Of course, what does it matter?"

“…… I'm in school these days, and I seem to be having a bit of trouble. ”

"Why didn't you say it earlier, but who bullied you?"

"It's not that I'm being bullied, but recently, it seems that someone has inquired about me at school, and I don't know if it's a bad person." Xiao En explained with some apprehension.

The words did give Zhang Tiancheng a little headache, he was not afraid of being threatened by someone, but when the people who had a relationship with him were really bad, the public security situation in the country was good, so it was difficult for any secret organization to infiltrate, but it was difficult to say in this foreign country.

It seems that you really have to deal with that secret well, otherwise it will be very troublesome if you use some means to arrest Xiao En or Xiao Man.

……

Late at night, after Xiao En beside him had fallen asleep, he quietly got out of bed and went to the secret room, took out the portal and entered the small world, and plunged into the laboratory in the small world.

Prepare to add two very special thrusters to the Northern Styx set, a special thruster inspired by the core device of the pneumatic repeater, which does not burn oil or electricity, and has an extremely high thrust-to-weight ratio.

The comprehensive performance can almost be compared to the thruster that can only be produced by the fourth-level scientific and technological civilization, and one is an ion thruster with an ultra-high thrust-to-weight ratio driven by cosmic energy.

In fact, Van Helsing's magic world has already used this technology to create a personal flying machine, so Zhang Tiancheng also has ready-made technology.

The reason why I haven't built it all this time is that it will consume a lot of Mithril, and it's really reluctant to rain, and the most cost-effective use of Mithril is to use it on portals.

It's just that now that the true qi has been sealed, the combat effectiveness has been reduced a lot, so the means of escape must be greatly improved, and I was still hesitant to waste Mithril to build a magic thruster.

But now that there is a secret organization targeting him, he may really have to take action in person, take the other party's den of thieves, and use ordinary personal flying machines to easily be discovered by the enemy, thus exposing his whereabouts.

But this kind of magic modified thruster is different, the sound is very small and it does not produce flames, but it purely accelerates the air flow through the thrust, as long as you make a pair, you can solve the traffic problem for a long time in the future.

After thinking about it for a long time, I finally made up my mind, turned on the device equipped with a handheld laser, entered a set of data, and took a piece of super alloy and began to process it.

In fact, all the design of the magic flying machine has already been completed, and very professional researchers were invited to help design it in that silent world.

The thruster designed is many times smarter than the personal flying machine that he brought with him in the Van Helsing world, whether it is the control system or the aerodynamic layout, it will also save a lot of Mithril materials.

……

Everything was ready-made, the materials were ready-made, and there was a very convenient laser machine, so it only took more than two hours to tinker with the magic version of the flying device.

The two thrusters are quite small, and they almost look like a pair of soles up to 10 cm thick, which can be fastened to the shoes of the Northern Stygian suit, and of course can be removed.

The total mass is about three kilograms, and the two large soles have two front and rear airflow spouts, respectively, which can produce a maximum of about 120 kilograms of airflow thrust.

In principle, of course, it can be made bigger, but I don't want to waste Mithril, because no matter how big it is, the air flow will not exceed the speed of sound, so no matter how fast this thing is, it will not be able to break through the speed of sound, of course, there is no need to waste it.

In fact, there is still an opportunity to upgrade in the future, because there are some special energy circuits that can ionize the air, and there should be an opportunity to add additional energy loops to this device in the future to ionize the passing air flow, so that the nozzle can produce a high-speed ion flow......

Of course, this is a later story, and it can only be used now, but then again, the traffic speed of being able to fly at subsonic speed is actually not slow, you must know that the passenger planes flying in the sky are all subsonic.

Although the amount of Mithril used was as low as possible, the small device still cost a whopping 15 grams of Mithril, which is by far the largest consumption of Mithril on a single device.

A few days ago, I got a pair of large portals with a diameter of 60 cm, plus 10 pairs of portals with a diameter of 1 cm to 10 cm, and it only cost 7 grams of Mithril, such a pair of small thrusters cost more than twice as much as the eleven pairs of portals.

looked at the 28 grams of Mithril left in the small bottle, and even put a seal on the bottle, and wrote a few words by the way: This thing is precious and can not be used......

By the way, he also put away the magic flying machine, and the device entered the storage space, and his eyes looked at the past, and a set of data information related to it suddenly appeared.

Unqualified pneumatic propulsion device: The special whirlpool force field formed by the Mithril circuit can drive the air flow, and the air flow speed is 300 meters per second, the propulsion effect is extremely poor, and the energy efficiency is very low, so it is recommended to add an ionization device......

It's a bit embarrassing to see the data introduction, and the unconscious system is a little unbearable, so I gave a suggestion directly, but I haven't mastered the ionization device yet, and I can't add it if I want to install it, so I can only use it.
