Qin Feng led his people to leave the Roman-controlled city of Zhizhi.

His subordinates Xun Yu, Dian Wei, Xu Chu, and Gao Shun were caught outside the city.

Xun Yu said worriedly: "The lord and the generals went out of the city safely, which is really a blessing for our army. ”

Everyone went all the way to the Xiongnu base camp not far from the city, which is now Qin Feng's base camp due to the submission of the Huns.

On the way, Qin Feng told Xun Yu about their plan to break the city tonight.

On the side of the Han army, the big tent of the Chinese army.

When everyone entered their own camp and was able to leave Zhizhi City safely, everyone's consciousness was completely relaxed. As Qin Feng explained his plan in detail, Cao Yuan, Liu and the others felt that it was quite inappropriate.

"Flying lights?" Yuan Shao thought about it carefully, and felt that his head was big.

Cao Cao was surprised: "The lantern will fly? Isn't it just the call of the sky lantern? ”

Liu Beixin said Cao Mengde, what you said is too right, but Qin Zijin is not lighting a sky lantern for the enemy, he is "lighting a sky lantern" for us.

Lighting a sky lantern is also called pouring some human oil wax, which is a famous torture in ancient times. The general process is to strip the person clean, wash it, wrap it tightly with something similar to plastic, and then dip it in oil and then turn the person upside down and light it until it is burned.

Liu Bei didn't believe that Qin Feng could make a flying lamp, because there had been no such thing since ancient times. Then, Qin Feng was bragging. Boasting will not break the city, but will waste time. Wasting time is wasting food, and if you waste food, you can't go home. If you can't go home, it is equivalent to dying, for Liu Bei, it is tantamount to him being "lit with a sky lantern".

So when Liu Bei put his hands in his sleeves, he muttered solemnly: "Dashuai, let's not "light the sky lantern", don't the enemy can't light it, but we waste time." Now that we're out of the city safely, let's get ready to get out of here and go home as soon as possible. ”

The crowd agreed, because they did not believe that the lamp could fly.

Qin Feng smiled slightly, and said in his heart that this kind of lamp was invented by Brother Pig, and now Brother Pig may not know where to arch the mud, so you don't know. He laughed, "Looks like you don't believe me?" ”

Liu Bei's big ears shook like an elephant. Said: "Dashuai, don't blame the cheats and speak out, it's not a matter of believing it or not, it's an impossible question." ”

Qin Feng was very confident. Then he said: "This is a mysterious lamp that can fly into the sky." Since you don't believe it, Ben Shuai will make one with his own hands and let you see your vision. ”

Everyone looked surprised.

Kong Ming lantern can also be said to be a kind of balloon lamp. The distance from the liftoff is basically the same as that of a balloon. It is divided into two parts: the main body and the bracket, the main body is mostly made of bamboo grate, the outside is made of light paper paste into a lampshade, and the bottom bracket is composed of a "grate" cut into bamboo.

Half an hour later.

In front of the big tent of the Chinese army, Qin Feng's side was surrounded by people on the inside and outside of the three layers. Among them were the ingenious soldiers in the army, and the more ingenious women among the Xiongnu people.

Cao Cao, Yuan Shao, Liu Bei and others surrounded Qin Feng in the circle.

The crowd watched closely as he made the lamp.

"Be careful to make the lampshade, with the opening facing down, and on the bottom bracket we use oil as a combustible....... The most important point is to remember. Place a cotton rope next to the fuel and light it at the same time as the fuel when it lifts off. ”

Qin Feng stretched out his hand in front of Cao Yuan Liu and made a cracking gesture, "When the cotton rope burns to the end, it will burn through the outer cover, and the lamp will lose its ability to float in the air and will fall." ”

His strategy of setting fire was to use a large number of Kong Ming lanterns to fly over the city, just like the cotton rope of the fuse burned out, and the Kong Ming lantern would fall to the ground. And the oil in combustion is wind-resistant. It will not go out, and it will splash again when it falls to the ground, forming a large-scale overfire.

The fuse is of different lengths to be able to fall at the same time. When the Kongming lantern falls, it will form a fire that covers the ground, plus the oil fire source that has been arranged in the city for a long time. As soon as the fire gets out of control, it will have the effect of burning the city.

"Can you really fly?" Liu Bei was deeply skeptical.

The flying principle of the Kong Ming lantern is the same as that of a hot air balloon, the fuel burns, and the air temperature inside the lamp rises. The density of the gas decreases, resulting in an increase in the buoyancy of the Hung Ming lantern. When the buoyancy force is greater than the gravitational force, the Kong Ming lantern rises.

This involves the principles of density, buoyancy, gravity, etc., which is very troublesome to explain to the ancients. Qin Feng didn't bother to explain, after all, the apprentice of the church starved to death of the master. For him, it is better for Cao Yuan Liu to be as "ignorant" as possible.

In a few moments, Qin Feng finished making a Kong Ming lantern. He beckoned Liu Bei and said, "There are many ringworms, you don't believe it the most." Ben Shuai will give you the first opportunity to put the lamp, so that you know that Ben Shuai said that you are ignorant and reasonable. ”

The second master's face was very red when he heard this, his eyes were squinted, and he stroked five strands of long hair. The three fat men stared at the ringed eyes, and the beard stood upside down. They felt the constant questioning of the eldest brother, if the lamp really flew, it could only mean that the eldest brother was "ignorant".

"Can't fly, can't fly, can't fly......." The three fat men began to mumble. The second master blushed even more, and stretched out his hand to signal the third fat man to shut up.

The third fat man said unhappily: "Second brother, you can't fly, if you fly, isn't our eldest brother stupid?" ”

The second master "red lips are dripping" and said: "Third brother, if you fly, you can defeat the Romans." As for the eldest brother, let's persuade the eldest brother, don't always question, but humbly learn from Qin Dashuai. ”

Liu Bei walked over and carefully took the Kong Ming lantern, which was the size of a 5-liter pure water bucket in later generations.

Qin Feng took out the fire twister and ignited the fuel on the bottom bracket.

When everyone retreated, their eyes widened, and as the Kong Ming lantern swelled as it was heated and expanded, their eyes also expanded.

However, the Kong Ming lantern did not fly out.

Liu Bei, who was holding the Kong Ming lantern, couldn't find the north for a while, and said seriously: "Dashuai, I guessed right, there is a lamp there that can fly into the sky." You see, it's been a long time, and I don't mean to fly into the sky. ”

"Hmm~." As soon as Liu Bei's words fell, the audience sounded the sound of gasping cold air. Cao Cao, Yuan Shao and the others were shocked, "Is it really impossible to fly into the sky, everything is taken for granted by Qin Dashuai?" ”

Qin Feng was angry, and scolded with a smile: "Stupid, how can you fly into the sky with the lamp, you let go, let go and fly." ”

"Hmm~." The audience resounded louder gasps.

In the sound of cold air, Liu Bei was stunned, his face was distorted, and his expression was extremely exciting.

"It's so stupid to miss ......." Cao Cao commented.

Yuan Shao shook his head and said: "There is no stupid deficiency, only more stupid deficiency, what I am talking about is that there are many ringworms." ”

The second master stroked five strands of long hair. Big Red's face was particularly red, and he turned his head to the side. The three fat men covered their faces.

Since ancient times, I am afraid that only Qin Feng dared to say that the lord of Shu Han was stupid. After Liu Bei learned the reason why the lamp did not fly, he was ashamed and angry. While I can't wait to find a crack in the ground to get into, I can't wait to strangle Qin Feng.

But Liu Bei is Liu Bei, and he has a deep foundation in the word "thick" in thick black science. I saw that his expression quickly became serious, and he let go.

Under the shocked gaze of everyone, Kong Ming's lantern flew into the sky. It was really soaring up to 90,000 miles, and it was suspected that it was an artifact soaring into the sky.

People stupidly looked at the Kong Ming lantern that lifted into the sky, forgetting everything around them.

Liu Bei, who had been questioning, was even more shocked, he raised his head, stared at the beads of his eyes, opened his mouth wide, and said: "I have lived for thirty-three years, and it is the first time I have seen the light in the sky." ”

Everyone was immersed in the flying lanterns.

Liu Bei was the first to come back to his senses, and he played his strengths. immediately threw his previous doubts out of the clouds, raised his arms and shouted: "Miracle, the lamp is in the sky, it is really a miracle." Only a wise and martial commander can create such a miracle. ”

Liu Bei clasped his hands into fists, bowed ninety degrees, and admired: "The cheating is really admirable for the intelligence of the handsome." ”

The second master blushed, stroked his beard and said, "It seems that the eldest brother needs to learn." Sure enough, there are many more. ”

When the three fat men heard this, their beards were upturned.

In the base camp, more and more people saw the flying magic lamp. When the distant magic lamp suddenly fell to the ground, smashing a flame on the ground. People's fanaticism for Qin Feng. Reached the apex.

The soldiers fell to the ground one after another, and only in this way could they express their awe of Qin Feng.

"Dashuai can actually make a flying lamp, he is really a god!"

Qin Feng was very embarrassed to say this, and said Kong Ming, the master robbed your Kong Ming lamp patent. You're a weird man. He thought again, Zhuge Liang is still young now, there should still be room for development, maybe he can invent a Zhuge lamp in the future, turn on the lamp or something.

Xun Yu couldn't hide the ecstasy in his heart, and said: "The lord created this magic lamp, why worry that the enemy will not break!" ”

Yuan Shao once again saw Qin Feng's transcendent ability, sighed, and said, "Brother Zijin, I don't know if this lamp has a name?" ”

This is actually Kong Ming Lantern, but now Zhuge Liang is still a little kid and has not yet invented it, so the world does not know. Qin Feng can't tell the truth, and no one will believe him when he says it, but he is regarded as a monster. So Qin Feng could only reluctantly say: "This is what Ben Shuai thought casually temporarily, and he doesn't have a name yet." ”

Everyone was shocked, and said that Qin Dashuai is Qin Dashuai, just think about it, and make a flying lamp, if you think about it seriously, then it will be worth it?

Cao Cao groaned slightly, "In this case, it is better to call Zi into the lamp." ”

So, from then on, people only knew that there was a child entering the lamp, but they didn't know that there was a Kong Ming lantern.

At this point, Qin Feng began to order his subordinates to rush into the lamp on a large scale overnight. There are not many ingenious male soldiers in the army, but there are many ingenious big girls and little daughters-in-law among the Huns.

The sub-entry lamp is magical, but the production process is simple. Ten thousand people worked together, and in less than an hour, tens of thousands of children were produced.

Qin Feng looked at the hour, there was still some time before 12 o'clock in the middle of the night. He calmly and handed down the command, "Guan Yu guards the east gate, Zhang Fei guards the west gate, Dian Wei guards the south gate, and Xu Chu guards the north gate." Gao Shun maneuvered. After the fire of Zhizhi City, the Romans must not be able to stand the roasting and run out, and they will be killed on the spot. ”

"Whoa!" The crowd will meet their fate.

Pawn Xu Gao Guan Zhang, as well as the military advisor Xun Yu, in this formation, it is definitely superb.

"Brother Meng De, Brother Benchu, and ringworm, you follow Ben Shuai, go to put the lights, and watch the battle nearby."

Cao Cao and Yuan Shao were overjoyed and felt that victory was in sight. After the city is broken, such things as gold and silver treasures will definitely be left behind, and they will be rich when the time comes.

Liu Bei was like everyone else on the surface, but in his heart he was thinking, "This son is indeed hanging in the lamp, but who knows what the specific effect is?" Qin Zijin dared to say that General Ben was stupid, and if he couldn't succeed, he would have to laugh at him for ....... ”

(I didn't expect such a surprise at the end of the month, when I looked online, there were six more alliance leaders, and Xiao Yi was blindfolded at that time.) didn't say anything, waited for Xiao Yi to ask Qin Feng for an idea in the morning, and fooled the unit to take an afternoon off. In the afternoon and evening, I will go all out to code words, and I will pass a chapter on a chapter, almost a chapter in two hours, and today I will be almost 6 or 7 more. ）
