At the same time, two dark silent paragliders were flying rapidly at an altitude of 200 meters.
This silent paragliding uses lithium batteries to drive an electric engine, so there is no noise generated when the fuel engine is running.
Moreover, the fan blades of the paraglider have been carefully designed and the air noise during high-speed operation is also very small.
Using equipment to make up for the shortcomings of strength is also the consistent development direction of Japanese ninjas.
In the early years, Japanese ninjas not only had to practice ninjutsu but also had to be proficient in chemistry because they needed to prepare various and strange equipment.
On TV, ancient ninjas threw a ball to the ground and could instantly ignite smoke. After the smoke disappeared, people also disappeared. This is actually not a fictional scene, but a real existence in history.
The ball used by ancient ninjas is actually a mixture of smoke bombs and flash bombs made using native methods.
During an explosion, the instantly generated strong light will cause the opponent's vision to be briefly blind, and the smoke is an excellent cover for retreat. Therefore, when the opponent's vision recovers and the smoke disappears, the ninja will run away long ago.
In fact, it may not be that it is really gone.
Ninjas are like chameleons, very good at hiding their whereabouts based on their surroundings.
When the target thinks they may have run away, they may hide on the beams, behind the target, or in the water, using thin bamboo strips that are used to blow arrows to ensure breathing.
Modern ninjas integrate scientific and technological achievements into ninjutsu, which gives ninjas better concealment ability.
For example, the super black materials on them, such as paragliding, are their modern methods.
At this time, the two people on the paragliding were communicating with each other through wireless intercoms, and one of them spoke: "Senior brother, should we control the distance a little? Avoid the other party discovering us."
"Impossible." The senior brother said with confidence: "Our current height is two hundred meters, and the distance from their straight line is about one thousand meters. At such a long distance, they can't hear any sound or see any sound at all.
Clues, even if the person directly below us looks up, we will never find us!"
The ninja in the lead thought he had done it perfectly, but he didn't expect that Ye Chen still noticed them.
After realizing that he was being targeted by the two of them, Ye Chen couldn't help but smile sarcastically on the corner of his mouth.
It seems that these ninjas are planning to bite themselves and not let go.
I just don't know when they are going to do it on themselves.
Not only did Ye Chen not have any worries about this, he was vaguely expecting it.
When he was young, he had watched some ninja-related films and cartoons, and was still interested in the ninja profession.
Therefore, he also wanted to compete head-on with Japanese ninjas to see what level of Japanese ninjas boasting about thousands of years.
So he decided not to change any of his next plans, but always pay attention to the movements of these four ninjas and see what they really wanted to do.
Twenty minutes later.
The convoy stopped downstairs of Kobayashi Ichiro's house.
Ye Chen and everyone entered the building and came to the top floor.
At this time, two ninjas riding in power paragliding were hovering in the night above the building, and the other two drove downstairs.
