At the beginning of the civil castle, the Ming God of War was a little panicked

Chapter 406 Miracles
On a midsummer night, the sky was exceptionally clear.

There were bursts of cicadas and frogs all around, revealing a peaceful and peaceful atmosphere.

A huge Kongming lantern rises slowly, like a kite, with a rope tied to its base, floating in the air with the wind.

Since the Academy of Sciences arrived in Chengdu, it has been flying Kongming lanterns every day to measure the wind speed and direction. By analyzing and sorting out the collected data, it is possible to find out the local airflow laws in the shortest possible time.

After several days of continuous observation, Mei Chun found that the local airflow is completely different in day and night, both in terms of speed and intensity.

The terrain here is very special. It is located at the junction of the Qinghai-Tibet Plateau and the Sichuan Basin. The wind speed in the basin is slow and the temperature is relatively high. However, the further west you go, the higher the terrain, the higher the wind power will be.

In particular, the heat accumulated in the basin during the day will form a unique heat dissipation system at night. After mastering this law, through calculations, the flight route of the Kongming Lantern can be worked out.

Then according to the distance of the local positions, the flight time is calculated, and the lead machine button is set, and a fully automatic bomb-dropping drone appears.

This night, the moon and stars were sparse, and the breeze was gentle, which was an excellent opportunity to attack.

On the plateau near Yazhou, the Uzang army has assembled.

Facing the continuous offensive of the Ming army, their life was not easy.

The money and food earned from building the railway back then are running low, and now they are back to the days of eating chaff and eating vegetables. If things go on like this, there is no need for the Ming army to attack at all, and I will die.

King Sangdu of Chanhua kept cheering up the soldiers, saying that the Ming army would definitely withdraw under the protection of the Buddha.

However, it's enough to say this once or twice, every time you say this, the people under your hands have long been numb.

In order to stabilize the morale of the army, Sangdu racked his brains and pondered every day how to make some miracles. After all, as the spokesperson of the Buddha, if he has no supernatural powers, why should people believe you?

This night, he came to the front line again and prepared some "miracles".

Making fireworks with the gunpowder that was painstakingly obtained, and setting off a few in the dead of night, it can be regarded as the manifestation of Buddha...

"Look, what is that?"

Suddenly there was commotion in the station in front of the formation, and some people pointed to the sky, as if they were facing a big enemy.

"It is the Buddha who came to the world!"

Someone yelled at the top of their lungs, and the others fell to their knees in shock.

"The Buddha manifests, the Buddha manifests!"

Sang glanced at the fireworks behind him in confusion, thinking in his heart, I haven't set it off yet, what's the matter?
The moment he walked out of the camp, he was stunned.

Overhead, a bright flying star hung in the sky.

What is this stuff?
Could it be a new weapon of the Ming army?
Sang Du's first reaction was to run quickly, because the Ming army often came up with some novel gadgets, which made people hard to guard against.

However, I have never heard of anything that can fly into the sky.

Now the only advantage on my side is the steep terrain of Uzang. If the Ming army can really fly into the sky, what a fart!
Sang Du gave up the idea of ​​running away, and observed carefully for a long time. The flying star was just wandering in the sky, but there were no other movements.

Judging from this appearance, it seems that it has nothing to do with the Ming army.

Could it be... a miracle really happened?

"This is the manifestation of the Buddha!"

Whether he is or not, let's say that first!

"You have all seen it. With the protection of the Buddha, what are you afraid of?"

"Send me an order. Tomorrow morning, turn from defense to offense. Let's attack down the mountain!"

The observation number descended slowly, and the recorder inside took out the data just collected.

It is actually very simple to measure the wind direction and wind speed in Kongming Lantern.

All you need is a piece of bamboo tube, or a stick, wrapped in a wet towel.

After the wind blows, the windward side will dry faster, and the leeward side will dry slower. You can see the North Star at night, so you can determine the wind direction.

Then by observing the speed at which the towel dries, the wind force can be determined.

This method has been used for more than ten days in a row, and I have basically grasped the law of the upper air flow.

The main function of this light tonight is to verify the accuracy of the previous plan.

Moreover, in order to prevent alarming the enemy, only one lamp was raised.

Belin, Mei Chun and the others got together and compared the data one by one.

Prior to this, they had already done detailed calculations, looking for the best attack position based on wind direction, wind force and other factors, and then back-calculated the data just obtained to verify it.

"That's right, it all fits!"

Belin nodded, then looked at Mei Chun, and said, "Do you have any questions?"

Mei Chun's face was very tense. After all, the research on weekdays is only at the theoretical level, and at most it reaches the level of exercises, but tonight is actual combat.

War means death, and he knows exactly how powerful the bombs carried by Kongming lanterns are.

Every bomb dropped meant someone died.

On the way from the capital, he had tried hard to convince himself that with or without himself, it would not affect the direction of the battle. The effect of the Kongming Lantern was only to speed up the end of the war.

Stop war with war, stop war with war.

Only by beating King Chanhua to the point where he knelt down and begged for mercy can U-Tsang be truly included in the territory of Ming Dynasty.

He tried his best to calm down, checked the two sets of data one by one, and then measured the location on the map.

During this process, his hands still couldn't help shaking.

Belin patted him on the shoulder and said: "There are many opportunities. If there is a problem with the data, we can act another day."

Mei Chun took a deep breath, and then said: "There is no problem with the data. In half an hour, the wind direction will turn to the southeast. Then is the best time!"

"it is good!"

Bellin immediately ordered: "Listen to my orders, and all are ready!"

The order was passed on, and everyone entered a state of combat readiness.

It only took a moment for the first batch of fifty Kongming lanterns to be assembled.

Mei Chun closed her eyes, quietly feeling the blowing of the night wind.

"Report, the wind direction has changed!"

A gust of wind blew by, Mei Chun opened her eyes, and saw that the wind vane on the flagpole had changed direction.

"It's now!"

Belin nodded and immediately ordered: "Let the sky lanterns fly!"

Immediately afterwards, a little flame appeared in the camp.

Fifty teams started to release the first batch of Kongming Lanterns.

In the night sky, the stars are twinkling, but the hazy moonlight is somewhat miserable.

On the pitch-black land, a Kongming lantern rose slowly and drifted towards the western peaks with the wind.

Under the lamp, there is still a dark thing hanging.

Then came the second, third...

Fifty Kongming lanterns are all vacated and gradually rise up, like stars in the sky.
