"Military advisor," Li Daoxuan became anxious upon hearing this: "After hearing this, why is there nothing wrong with you?"
He couldn't make this trip in vain.
"Yes." Xia Yu smiled: "You are a cavalry. Of course you are not needed on the water or in the air, and you can't help in the siege."
"So, after a day or two of rest, you can go to General Liu's place."
"If there is a small group of cavalry coming from the Heyang pontoon to harass the Zheng army, you will be responsible for dealing with it and cover General Liu's attack on the city."
"In addition, after the city is defeated, Wang Tai will definitely break through."
"However, since there are no roads to the north, west or south, it will have to flee northeast to Shezhou in Hebei Province. Then you should just wait and see."
Li Daoxuan was overjoyed when he heard this.
On the Hanoi battlefield, Wang Tai, the fake king of Zheng and Song Dynasty, was the biggest fish. Xia Yu left him with great care.
Moreover, this person sounds pretty awesome. Being able to defeat such an opponent gives me a sense of accomplishment.
"That's great, the general has taken the order." The little prince was satisfied.
"By the way," Xia Yu remembered something again, turned to Huang Junhan and said, "General Huang, I almost overlooked something."
"Military advisor, please speak."
"When I come to Baiya, I probably can't hide it from Zheng Jun."
"Zheng Jun has been deceived by me recently. If he knew I was coming here, he would be frightened and be on guard. This is not good."
"So, we have to put on a show to confuse the enemy and make them relax their guard."
Huang Junhan made sense when he heard it: "The military advisor only gives orders, and the general will obey them."
"First of all, if you arrange to let the wind go, say that I am arrogant and domineering, and I am very dissatisfied with your inaction. However, I don't know how to fight on the water. I just reprimand you severely and order you to defeat the enemy as soon as possible."
"Secondly, I make great fanfare every day, arrange fine wine, delicious food, singing and dancing, and say that I am a very extravagant person and it is difficult to serve me."
"With this two-pronged approach, Zheng Jun will surely be relieved."
Xia Yu touched his chin and smiled sinisterly. He felt that he should have a nickname, called: "You will feel uncomfortable if you don't cheat others for a day."
When everyone heard this, they were all happy: The military advisor is really bad!
In addition to confusing the enemy, he also arranged a big advantage and disadvantage for himself. Alas, such a good thing is really enviable.
"Okay, everything is settled, let's all leave. I also want to take a rest."
The journey was dusty and he was tired.
"Farewell to the military advisor."
Seeing that Xia Yu's command was determined, and in just a short moment, he solved the trouble that had troubled everyone for more than a month, everyone was in admiration.
The disciples of Guigu really deserve their reputation!
…
In the next three days, Xia Yu's strategy of confusing the enemy really worked.
The Zheng troops in Mengjin, Heyang and other places who were originally frightened thought that the generals of the Tang army were at odds with each other and Xia Yu was not able to fight by water, so they gradually relaxed.
this day.
Early in the morning, Xia Yu just got up. She drank too much last night and had a hangover-like headache.
It's very hard to do a full set of dramas and have sex every day, isn't it?
At this moment, Huang Junhan came, with an excited expression on his face: "Commander, good news, the hot air balloon has been made!"
"That's great." Xia Yu cheered up: "Let's go and have a look."
When the two arrived at the craftsman camp, they saw a crude version of a giant hot air balloon, which was tied to a hanging basket with ropes and fixed in the open space.
"Military advisor." Pei Xuan greeted him happily. He had been very busy in the past three days.
"Thank you for your hard work." Xia Yu smiled, patted his shoulder, and glanced at the hot air balloon: "It looks good, have you tried it?"
"Not yet." Pei Xuan shook his head and said respectfully: "I'm waiting for you to take the helm."
This thing was unprecedented, and everyone was unsure, so as soon as it was built, they immediately asked Xia Yu to give guidance.
Xia Yu circled the hot air balloon and looked at it carefully.
The most critical thing about this thing is the airbag, which must be thin and airtight, otherwise it will either not be able to fly or not be able to fly very far.
Before taking two steps, he reached out and touched the huge air bag lying on the ground.
It is true that the thinnest and most dense silk is used, but it feels a bit strange, seems to be too smooth, and has a faint strange smell.
"Is this the smell of paint?" Xia Yu turned her head in surprise.
"Yes, military advisor!" Pei Xuan said hurriedly: "You said that there must be no air leakage, but I made a small Kong Ming Lantern and tried it. Even the finest silk has leaks."
"Bizhang and the craftsmen studied it and decided to apply two layers of varnish on the silk. After it dries, the pores can be sealed."
Xia Yu was stunned. He had never actually developed a hot air balloon, so he lacked experience.
Unexpectedly, there was such a big bug in it, but Pei Xuan was quite talented and solved it easily.
"Well done." Xia Yu nodded repeatedly with satisfaction: "If this plan is successful, I will remember you as a great contribution!"
"Thank you, Commander."
Pei Xuan was overjoyed. Even if he came from a famous family, it would not be easy for him to get promoted if he didn't have merit.
"Hurry up and try lighting a fire." Xia Yu couldn't wait.
"promise."
Huang Junhan and Pei Xuan quickly asked the craftsmen on standby to start. One craftsman came forward and lit the stove in the hanging basket with a torch.
Immediately, the flames rose, the heat rose, and the smell of oily smoke came to my face.
"What kind of oil is burning?" Xia Yu thought about it.
"Back to the military advisor, the burning oil is linseed oil." Pei Xuan said hurriedly: "Although it is more expensive, the tung oil smoke is too heavy and there is no way anyone can stand in the basket."
"Actually, it's best to burn whale oil." Huang Junhan interjected: "That thing has strong firepower and almost no oil smoke. Unfortunately, it is too expensive and the quantity is small, so it is not realistic at all."
"Then let's not mention it." Xia Yu waved her hands hurriedly.
He knew that whale oil was a luxury product only for nobles in ancient times, and even the ever-burning lamps in many ancient tombs were made of whale oil.
As he spoke, the huge air bag slowly inflated, and the changes were visible to the naked eye.
Seems to work!
Everyone at the scene became excited, held their breath, and stared at the hot air balloon: Can such a big thing really fly into the sky?
I saw the air bag becoming more and more inflated, and slowly, it slowly rose from the ground and floated into the air.
By the time it was a quarter of an hour, the air bag had been inflated more than half and was completely off the ground, like a huge house suspended in the air.
Suddenly, a sharp-eyed craftsman shouted: "It's moving, it's moving, the hanging basket is moving."
Sure enough, under the stunned gaze of everyone, the huge hanging basket measuring four or five square meters seemed to have escaped the gravity of gravity and rose up into the air swayingly.
In the blink of an eye, it had flown several meters high. It was not until it was caught by a thick fixed rope that it stopped rising.
"Hahaha!" Xia Yu laughed and clapped her hands: "It's done! It's done!"
It’s really flying!
Although they had already had psychological expectations, everyone at the scene was still greatly shocked when they saw the hot air balloon actually flying!
There are three hundred kilograms of counterweight in the hanging basket!
In other words, if someone else comes up, there will be no problem.
It turns out that people can really fly!
If they hadn't made this thing with their own hands, everyone would probably think it was a divine object and worship it when they first saw it!
They truly witnessed a miracle!
This is a giant step for mankind!
"Military advisor," Huang Junhan's voice trembled with excitement: "You are really amazing. This hot air balloon can really fly. It's incredible!"
"Here, isn't everyone a god?"
"Haha, it's not that exaggerated. This is not a miracle, this is the power of observing things, do you understand?" Xia Yu looked proud.
He made history again and became the first person to invent a hot air balloon!
"Military advisor, with this thing, it will not only be convenient to harass the enemy troops, but if it is used for reconnaissance, the enemy will probably be able to hide away!"
Pei Xuan's eyes were so bright that he thought of many things in an instant.
"Smart." Xia Yu gave a thumbs up with great appreciation: "As long as you are familiar with the performance of this thing, it has many uses."
"General Huang, are your warriors ready?"
"Ready." Huang Junhan said hurriedly: "There are a hundred warriors who are not afraid of life and death on standby. Do you want them to come now?"
"Don't try it here." Xia Yu waved her hand.
"There must be a Zheng Jun sentinel nearby. You arrange for someone to drag the hot air balloon to the wild, test it quietly, and get familiar with its lifting, lowering, load capacity, speed, range and other properties."
"Remember, it must be kept confidential."
"promise."
"By the way, when will the Zheng family deliver the large amount of silk they need?" Xia Yu was very concerned about this.
"Back to the military advisor," Huang Junhan said hurriedly: "The Zheng family has completed the dispatch of the required silk. We will start shipping it from Xingyang today, take the waterway, and arrive at Baiya in the evening."
"Very good. Let's start tomorrow and build a hot air balloon at full speed. Before General Liu can conquer Hanoi, Mengjin City and the Heyang Floating Bridge must be solved."
"No." Huang Junhan accepted the order.
Xia Yu knew that in just a few days, it would be impossible for Tang Jun to fully explore the performance of the hot air balloon, and it would also be difficult for him to control it skillfully.
Such a hasty attack, coupled with going deep behind enemy lines, will inevitably pay a bloody price and huge casualties.
However, Ci does not have troops, Luoyang must encircle him as soon as possible, he has no choice!
