This is a good point of observation. Even if you find it, it is not easy to touch the whistle. But as long as he finds someone attacking, he can shoot in the tree and catch the attacker off guard.

In addition to this secret whistle, there is also an open whistle in the yard. However, this open whistle is outside the gate. He can rely on each other with the secret whistle.

There should be three people in the room, one on the first floor, one on the second floor, and one on the basement. This room is only two floors high. There is radio wave sound in the basement, and there should be a radio operator.

Zhou Yun moved to the back of the yard. This was the back wall of the building. Outside the back wall, there was also a big tree, but the branches that reached the building were cut down. Maybe he was worried that someone would touch the roof of the building along the big tree.

Top of the building?

Zhou Yun immediately got up the tree and looked at the roof of the house from the tree.

This is the only way to enter the small building.

But how to enter?

When I climbed the stairs, there were no windows on the back wall of the building, but there were only one whole wall and no water pipes. Because the water pipes were placed on the front wall.

If you can't jump over the tree, it's nearly ten meters. Once you jump, you will fall between the building and the big tree. You will land without an parachute.

umbrella?

Zhou Yun's mind flashed.

In the 21st century, he was a special forces soldier. Among the majors he studied, there was a paragliding.

Paragliding originated in Europe in the early 20th century. At that time, a man grabbed a cloth umbrella and jumped from a high altitude. As a result, he was not killed. Instead, the cloth umbrella sent him safely to the foot of the mountain fifty meters away.

So people paid attention to this new project.

By the 1960s, some climbers glided down the mountain by parachute and experienced a wonderful feeling and fun, thus creating an emerging aviation sports program.

The original paragliding was borrowed from the wing-shaped square paraglider used for aircraft parachuting. It mainly focuses on descent, has fast descent speed and good safety performance.

Zhou Yun has no paragliding now, so he can only return to his ancestors and learn from the first person who jumped from the mountain with a cloth paragliding.

However, the tallest building nearby is dozens of meters away from that small building. If you jump down with a cloth parachute, you will jump to a distance of ten meters at most.

After Zhou Yun came back, he went to the debris room.

There are a lot of things placed in the debris room. They are all things Zhou Yun usually sees what he wants to buy when he goes shopping.

In the utility room, Zhou Yun found a large oil cloth and found a few steel bars.

Take out an electric welding machine and weld the steel bars into a tripod. Then tie the oil cloth to the tripod, and then use glue to seal it.

In this way, a large umbrella of tart cloth was completed.

All these were done, only half completed.

Zhou Yun took out a hand-cranked electric fan. In the Republic of China, there was no electricity in many places, so the merchants made hand-cranked fans, which were very popular.

This fan only needs to shake the spring for dozens of times and tighten it. After that, it will drive the gears as the spring runs, and the gears will drive the fan blades to fly. Every time it is used for a full spring, it can rotate for a few minutes.

When Zhou Yun was shopping, he bought a few hand-crank fans and now he is using them.

Secure the hand-crank fan into the tripod so it doesn't fall off.

Under the tripod, three thick ropes were hung and tied into a triangle belt. Zhou Yun's hand would pull on the triangle belt.

After doing this, Zhou Yun drove away and went to a remote place.

First, he chose a three-meter-high cliff, took out the umbrella, put on a sufficient clockwork, and started the fan. Immediately, the wind power of the fan generated a thrust, pushing Zhou Yun forward.

Zhou Yun jumped from the sky with an oil cloth umbrella hanging in his hand.

It landed safely. After landing, Zhou Yun immediately turned off the fan.

Afterwards, Zhou Yun went to jump to a height of five meters, seven meters, and ten meters, without any problem.

A distance of ten meters is enough.

Zhou Yun drove home and modified the homemade "pargliding" to make it more perfect.

The next night, Zhou Yun came to the courtyard again.

Instead of going to the tree he climbed up before, he came to a tall building.

This tall building is right next to the courtyard, more than 30 meters away.

By twelve o'clock in the evening, the lights in Shanghai gradually went out.

The lights were still on in front of the small building.

Zhou Yun activated the hand-crank fan from the high building, grabbed the triangle belt of the umbrella! He jumped towards the direction of the small building.

This jump almost turned a little crooked. Fortunately, Zhou Yun controlled it.

Today is the beginning of the moon. The moon is very dark and is blocked by the clouds. Shanghai is trapped in the darkness.

No one saw Zhou Yun’s jump.

It went smoothly, Zhou Yun landed on the roof of the small building.

Zhou Yun took the "pargliding" and leaned on the roof and looked downstairs.

The secret whistle sitting on the tree could not see what was above his head due to the cover of leaves. He could only see the situation under his eyes. Therefore, he did not know that someone had descended to the small building.

And the sentry at the door didn't know what was going on upstairs behind him.

Zhou Yun felt relieved. He had to change the sentry in more than two hours, and he had to go into the house before changing the sentry.

The door from the rooftop to the second floor was locked. But this did not hurt Zhou Yun. He took out his tools and opened the lock in less than a minute.

From the roof of the building, it is the second floor. According to yesterday's observation, Huo Zheng should have lived on the second floor. Zhou Yun's target is him.

Zhou Yun heard breathing sounds in the room on the left side of the second floor. Needless to say, it should be Huo Zheng. It is impossible for people on the first floor to come to the second floor.

Zhou Yun took out a piece of incense from his body. This was seized from the Military Control Commission. That time in Macau, the military control personnel used incense to deal with Zhou Yun.

I lit the mist smoke, blew the smoke, and blew the smoke into the room where someone was sleeping.

After blowing for five seconds, Zhou Yun stopped blowing. Because he heard the sound of breathing in the house changed, proving that the man had been fainted.

After confirming, Zhou Yun took out the lock-opening tool, opened the door, and slipped in. After entering, he gently closed the door.

All of this did not alarm the people on the tree or the people at the gate.

After Zhou Yun entered the room, he came to the bed and saw the person sleeping in the bed. It was indeed Huo Zheng.

Zhou Yun was not here to kill them, he was here to find something.

He came to Huo Zheng's bed, tripped on his pants, and found a bunch of keys.

Zhou Yun took the key and came to the safe.

I took out the receiver, listened to the password lock, and found the correct password. Then I inserted the key into the handful and the safe opened.

Zhou Yun first remembered the position and order of the items placed in the safe. Then he took out the information.

Zhou Yun didn't get a penny of the golden ocean and fiat currency in the safe.

If you lose money, Huo Zheng will definitely find out!

Zhou Yun just took out the information from the safe, took out a mini camera, and took photos. It took him ten minutes to take all the information.
Chapter completed!
