Belin personally brought a group of people to study air flow every day and how to control the height and orientation of the Kongming lantern.

The first batch of samples were quickly made, but it was much smaller than the one Mei Chun made. Not to mention carrying a manned person, it would be difficult to carry a dog.

Mei Chun was a little puzzled at first, but then she thought that since it was a sample, it should be just for testing.

"The first batch of Kongming lanterns are ready to test flight!"

"yes!"

Mei Chun saw someone bringing out ten Kongming lanterns, one group of people was responsible for recording, and the other group began to operate.

They first hung a brick at the bottom, and after checking, they began to ignite the fire.

As the flames in the lamp became more and more prosperous, slowly, ten lamps flew up one after another.

"Report, No. 1 deviates!"

“No. 2 deviates!”

“No. 3 deviates…”

For some reason, lights kept deviating from the expected direction and drifted away.

Belin sighed and said, "Make a record."

Mei Chun slowly stood up from the rattan chair and said, "Dean, the airflow is unstable now, and it is normal to deviate."

"You are right, the airflow is unstable now, but..."

Belin shook her head and said, "This is the difficulty we have to overcome!"

Mei Chun asked: "The higher the altitude, the more disordered the air flow is. Sometimes there is no way to follow, and there is nothing to do about it."

"There is no way, I have to find a way!"

All the first batch of samples deviated from the expected position, and the experiment ended in failure.

Belin took people back, took out the pre-set and on-site records, carefully compared them, and found the problem.

For some reason, Mei Chun felt a little depressed.

Because the early theory was proposed by himself, none of the ten lamps in the first experiment met expectations, which made him feel a sense of frustration of failure.

"Mei Chun, tell me!"

"Um?"

Mei Chun was in a daze, but suddenly she was named by Belin, and she didn't react.

"From the record, today's wind direction is a bit abnormal. What do you think is the reason?"

"When the wind direction..."

Mei Chun took back her mind and thought about it seriously.

“I think it’s related to yesterday’s heavy rain.”

"Oh? Tell me in detail!"

"After the heavy rain, there is water accumulation on the ground, and the weather begins to evaporate when the weather is clear, and the evaporation rate is related to sunlight and wind. Today's weather is very clear, and the evaporation rate of water must be extremely fast, which affects the wind in the sky..."

Mei Chun explained, and the other students quickly recorded and kept nodding.

After listening carefully, Belin said, "Can such a wind direction and size be predicted?"

"It is OK in theory, but at our current level, we can only roughly predict."

"You can modify the plan and conduct a second experiment in the afternoon!"

"good!"

Mei Chun took the original plan and made corresponding modifications and adjustments according to her own understanding.

He was the only person who had personally climbed high altitudes. These experiences that were almost exchanged for life were irreplaceable to others.

Two hours later, the second test began.

This time, there were still ten lamps, and a marked brick was hung under each lamp, and it began to rise.

Mei Chun stared at the trajectory of these lamps with her eyes tightly, and she was extremely nervous.

"Report, No. 1 deviates!"

Mei Chun's heart skipped a beat and turned it apart again!

“No. 2 deviates!”

“No. 3 deviates…”

Every time someone reported a deviation, Mei Chun felt a little depressed, and he even wanted to do it himself.

“No. 5 enters the expected track!”

The audience suddenly shouted, it was done!

Finally a light was traveling along the expected route and entered the target area.

At this moment, Mei Chun was moved and wanted to cry.

As the saying goes, a scholar died for his confidant. He thought that he was summoned by the emperor. He went from an unknown student, thanking the holy grace, copied books in Nanjing, and came to Beijing with a large number of ancient books and lonely books. Then he sat on the Kongming lantern and went through life and death...

When he was in heaven, he was even ready.

I was ready to smash myself into pieces, but my corpse was gone.

At that time, the only belief in his heart was that he hoped to see the emperor again.
