It was night, dark clouds covered the moon, and suddenly there was a strong wind.
Zhang Mao asked: "The wind has picked up. Do you want to inform Ankru that the attack time has been postponed?"
Bei Lin looked solemn and said: "Don't worry, let's release the observation light!"
"But, such a strong wind..."
"The airflow on the ground will change every time it reaches a certain height, both in direction and intensity. It requires observation before we can draw conclusions."
"Oh, that's right, then you continue!"
Zhang Mao felt that he was an amateur, so he had no choice but to keep his mouth shut.
The two manned Kongming lanterns rose slowly, drifting in the wind, flying higher and higher, and gradually only two small shining light spots remained, like stars in the sky.
However, the night sky was dark, and these two light spots became particularly conspicuous.
Zhang Mao couldn't help but ask: "This place is too close to the city. Will the enemy notice it?"
Beilin shook her head disapprovingly and said, "Even if someone sees it, they won't think that a disaster is coming, so it doesn't matter."
These words are true. In this era, no one would know that this thing could be a siege weapon unless they saw it with their own eyes.
A quarter of an hour later, the two lights slowly lowered.
After receiving the observation data, Beilin relaxed her frown and said, "As expected, the upper airflow is stable, and we will attack as planned!"
Zhang Mao was unsure. He could not understand that the wind in the air would change with altitude.
I took the observation data from Beilin's hand, but found that I couldn't understand it at all.
"Are you sure it's okay?"
"Don't worry, we already discovered last night that the low air flow here is very chaotic and the wind strength and direction are constantly changing. However, when it reaches above 1,500 feet, it becomes stable and is very suitable for air strikes."
"Fifteen hundred feet?"
Zhang Mao opened his mouth wide. The two lights just flew so high. What was even more terrifying was that there were people above.
I thought that the Academy of Science was just a group of scholars who wrote and calculated all day long, but I didn't expect that the games they played were all very difficult.
One thousand five hundred feet!
If the equipment malfunctions, or the operation is slightly careless, and it falls from above, it will be difficult to keep the whole body, let alone survive.
Not to mention having to observe and record data, every time you take off, you are risking your life.
When Fan Mingchen followed him up once, he was so frightened that he almost peed his pants and laughed at them. Now looking back and thinking about it, if he had been allowed to go up, the scene would probably have been even more embarrassing.
The Academy of Sciences... is so scary!
Near midnight, Beilin directed the staff to conduct the last observation. The data showed that the air flow at high altitude was still stable.
"Everyone, get ready to release the Kongming Lantern!"
The students automatically formed groups of three to assemble sky lanterns, install bombs, and debug the detonating device.
Zhang Mao was bored and wanted to help, but was stopped by Beilin.
"Brother Zhang, don't move around, it will explode!"
"ah……"
Zhang Mao quickly retracted his hand and said, "If this thing explodes, will we all have to finish playing?"
Beilin nodded and said: "Absolutely!"
After Zhang Mao heard this, he subconsciously took two steps back and kept his distance.
Seeing this, Beilin comforted her: "Brother Zhang, don't be nervous. If it really explodes, all the bombs will detonate. It's useless for you to step back a hundred steps."
Zhang Mao became even more nervous and thought to himself, he would try not to cooperate with the Academy of Sciences in the future, it is too scary.
Tabriz City, Malaq Observatory.
The monk Zamaladin III stared at the two stars in the night sky with a very solemn expression.
"Strange, when did these two stars appear?"
"Father, what are you talking about?"
"Starting from last night, two stars suddenly appeared in the northeast, and their movements were irregular. They appeared and disappeared sometimes, making it difficult to understand."
Jamaladdin IV said: "Father, let me see."
There is a large telescope on the observatory for observing stars. Over the past two hundred years, the Zamaladdin family has used this telescope to formulate the "Time Keeping Calendar", "Suvari Kova Beibei Star Compilation",
Many astronomical works such as "Varikova Qibi Star Compilation" were introduced to the East during the Mongolian expedition to the West, making important contributions to the cultural exchange between the East and the West.
Just last night, Jamaladdin III discovered two stars of unknown origin. Just when he was about to conduct further observations, they mysteriously disappeared.
The situation tonight was even more strange. Dark clouds covered the moonlight and the starry sky, but these two stars suddenly appeared again.
Jamaladdin IV quickly found the positions of the two stars through the telescope.
"Father, these two stars seem to be stationary. Could they be new stars?"
"It can't be a star. Otherwise, why would it suddenly disappear?"
"However, in the field of view of the telescope, the positions of the two stars have not changed."
"Let me take another look."
Jamaladdin III came to the telescope again and said with a strange expression: "Hey, he disappeared again!"
"The one who was there just now!"
Jamaladdin IV hurriedly approached, and sure enough, his vision was dark and there was nothing.
He raised his head and looked towards the sky, only to find two points of starlight moving downward.
"Father, look!"
Jamaladdin III looked into the distance, then adjusted the field of view of the telescope, and sure enough he captured two points of starlight again.
"The movement trajectory is too abnormal, I have never seen stars like this!"
Jamaladdin III became excited as he spoke.
He has followed his father to observe the stars since he was a child, and is familiar with the position of every star in the sky. These two stars seem to be a completely new type.
If the motion patterns of these two stars could be found out, it would definitely cause a sensation in astronomy!
Jamaladdin III kept adjusting the lens and closely followed the two stars until they dropped to the horizon and completely disappeared from his field of vision.
"Quick, take notes!"
Jamaladdin IV took out an ancient parchment book and began to record the discoveries he had just made.
Jamaladdin III found several thick books and tried to find similar clues from the observation records of his predecessors.
"Father, look, he's here again!"
Jamaladdin III raised his head, and sure enough, two light spots rose again in the distance.
The father and son were busy again, observing and recording, and they were very happy.
"Father, I have an idea!"
Jamaladdin IV suddenly said: "These two stars travel together, rise together and set together. Does it contain some kind of meaning?"
"What's the meaning?"
"Father, think about it. His Majesty the King has just signed an alliance with the Timur Khanate. The two countries will advance and retreat together, and these two stars appear. Isn't it God's will?"
Jamaluddin III was stunned for a moment and said dissatisfied: "Our Zamaladdin family has been observing the stars for generations, and it has been two hundred years. How can you still believe this?"
"Father, it doesn't matter whether we believe it or not!"
Jamaladdin IV showed a confident smile on his face and continued: "As long as His Majesty the King believes it is enough!"
