Chapter 174 Hydrogen Balloon
Not even three moments later.
"Hydrogen balloon, what is a hydrogen balloon?"
Everyone looked at Qin Rubing blankly, their eyes full of confusion and curiosity.
They seemed to have never heard of this strange thing and were full of expectations and imagination about it.
Qin Rubing smiled and explained patiently:
"A hydrogen balloon is a balloon that can float in the air. It is filled with hydrogen and can rise very high and far.
We can tie banners to the bottom of hydrogen balloons and let them float in the air to attract more people’s attention.”
After hearing this, everyone suddenly understood and nodded to show that they understood.
At this time, Qin Rubing began to assign tasks:
"Bai Lu, you and Bai Shuang go prepare the banners. Make sure they are eye-catching. As for the hydrogen balloons, leave it to me. Ju Hua, Ye Er, Ye San, Ye Si, you stay and help me."
After the meeting, Qin Rubing asked Juhua and the others to wait for her in the main room, and she walked to a locked small house in the yard.
She took out her key, unlocked the door, and walked in.
No one had ever entered this room because it was her private vault and no one except herself had the key to open the door.
Qin Rubing gently pushed the door open and then quickly closed it.
After entering the room, the scene that greets you is surprising - it is just an empty room with nothing in it.
However, in reality, there is an unknown secret hidden behind this seemingly ordinary room, and this is exactly the deception that Qin Rubing deliberately set up.
Qin Rubing called out "Xiao Yu", "I want to enter the space."
"Yes, Master."
In a flash, Qin Rubing entered the space.
She quickly collected a batch of equipment for making hydrogen balloons, including hydrogen cylinders, inflating nozzles, balloons and pressure reducing valves.
Qin Rubing prepared enough materials and tools to make 100 hydrogen balloons.
After she brought these out of the space, they filled up half the room.
She then called Juhua, Ye Er, Ye San, Ye Si and others to come in and help her inflate the hydrogen balloon.
"Can these things be used to make hydrogen balloons?" Juhua looked surprised.
Qin Rubing smiled and demonstrated step by step how to inflate a hydrogen balloon.
“Connect the outlet of the hydrogen cylinder to the pressure reducing valve, and then connect the inflation nozzle to the output end of the pressure reducing valve.
Make sure all connections are tight and leak-free, and check that the valves on the hydrogen cylinders are closed.
Slowly open the valve of the hydrogen bottle and watch the balloon gradually inflate.
During the inflation process, always pay attention to the size of the balloon to avoid over-inflation that may cause the balloon to rupture.
When the balloon reaches the desired size or feels full, close the valve on the hydrogen cylinder and remove the inflation nozzle from the balloon.”
Juhua and her friends studied the whole process carefully and quickly mastered the basic skills. They divided the work and worked together, and they worked faster and faster.
Bai Lu and the others quickly wrote a hundred banners and slogans.
At 3 p.m., the southern military camp.
"Look, what is that?"
Suddenly, a hundred hydrogen balloons appeared above the camp. They hung in the air like little suns, attracting everyone's attention.
These hydrogen balloons seemed to be announcing some important news to people, making people look up curiously.
A closer look revealed that there was a banner hanging under each hydrogen balloon, covered with various slogans:
"The Eastern Army has recaptured Dingyang City! The Eastern Army will win! The East is invincible!"...
These slogans were full of strength and confidence from the Eastern Army, but they horrified the Southern Army soldiers who saw them.
