Long Tianyu thought that it must have been a fake to have the Black Dragon water before it was crowned, because the Dragon was a symbol of China, but in the scientific realm, there had never been such a creature on Earth before. Other than the dinosaurs, even the dinosaurs had already become extinct before humans were born.

Right now, the allied army was under siege and was in imminent danger. It was time to do all sorts of things, including advertising, but to kill the White Snake and call it the Scarlet Emperor's son.

Since Ying Zheng is to use the Black Dragon's water to protect the Great Qin, why don't I use the dragon as an avatar to plead my crime against him, rebel against him, and follow the logic of heaven? I have to do it this way and do it the other way, to let the people who embrace me shake themselves. He then asked Xiao He: "Do you know how to draw dragons?"

Xiao He nodded, he did not understand what he meant and asked: "What's the use of drawing a dragon?"

Long Tianyu laughed: "Have you heard the story of using your son's spear to attack your shield?"

Xiao He pondered for a while and suddenly said: "Tian Yu wants to use the dragon as a divine object to protect the King of Qin's Black Dragon, but how should I do that?"

Long Tianyu said in a profound tone: "Back then, the people believed that the unification of the six nations of the First Emperor of Qin was related to the protection and protection of the Black Dragon, and would naturally support the heavens. But now that the Qin Dynasty has fallen, and we have harmed the people, we created a green dragon and declared a crime of the Qin Dynasty in front of everyone, indicating that the Divine Dragon would no longer protect the Great Qin, and that the Divine Dragon should be commanded to lead the army under the True Dragon, and overthrow Tyrannical Qin.

Xiao He was overjoyed upon hearing this: "Good plan! But how to demonstrate it in front of the crowd? You must know that a Divine Dragon can dive into the sky, and there are no rivers passing through Pei County. Naturally, a Hidden Dragon cannot, only … "Only the heavens will find this difficult."

Because there were no airplanes or rockets or other flying objects in the ancient times, it was believed that apart from the gods or immortals, only the winged birds of elders could fly into the sky.

Long Tianyu searched his mind for anything that could make objects fly in the sky, as they were even vividly flying in the air without any clues being discovered. According to the mechanics theory, he had to overcome the gravitational pull of the earth, but there were no power devices in the ancient times, so the propeller was obviously useless.

How can one apply the subtle relationship between gravity and buoyancy in an era of backward technology? The image of a hot air balloon suddenly appeared in his mind!

There, the relation of balloon pressure can be used to generate buoyancy, just like the hot air balloon around the world floating in the air.

After thinking it through, he said excitedly: "The specific details can be announced by Tian Yu during the evening assembly. Right now, I shall bother you to draw out a green dragon for your reference!"

Although Xiao He did not understand what he was doing, but looking at how confident he was, he calmed himself down, thinking that it was best not to waste any more time, he immediately asked for orders to go ahead to draw, while Long Tianyu hurried back to his room to design the steam installation.

At night, the Qin Soldier did not attack the city again. Perhaps she was recuperating and studying the next round of attacks, bringing about a moment of peace before the storm.

Long Tianyu called Cao Can, Xiahou Ying and the other brothers over for a discussion, while Lu only had Lu and Lu Sheng, the rest of them were not qualified to participate in this kind of military aircraft conference. As expected, when he told everyone about the MC, other than Xiao He, who knew about it beforehand, everyone else was shocked. They were all subdued by his talent and bravery and didn't know what to say.

After all, the Lv Chen had once worked with the prime minister before. Those who had seen such a grand scene, sized up Long Tianyu as if they had just met each other, and sighed: "This old man has only met one true hero in my life, compared to Tian Yu, I'm afraid that there are still many others who are inferior.

Of course, Long Tianyu didn't know who he was talking about, after exchanging a few polite words, he divided the tasks one by one. Lv Chen, Lu Sheng and Fan Kuai were in charge of defending the city, Cao Can was in charge of training the new recruits to set up the formation, Guan Ying was in charge of doing business with cloth, so she was in charge of sewing the green dragon.

Long Tianyu told the three that the most crucial part of the Azure Dragon's sewing process was to ensure its seal and volume. After that, he discussed with Xiahou Ying about how to create the pressure steam furnace and fuel.

The next day, the distribution work started to proceed methodically, and Long Tianyu was to stand on the city wall to command the battle. Fortunately, the Qin Army did not invest too much troops, and each of them received their own injuries, so she was not too much of a threat.

In the next ten days, the reinforcements for the Qin Army still did not arrive. Everyday, only two to three thousand people would take turns to attack the city, and there would be more than ten of them being killed or wounded. Furthermore, they would all be killed by Long Tianyu at most three to four times, scaring the enemy generals to the point that they did not dare to come alone to fight.

That night, the strong men that Zhu Yu had brought with him reunited with the Qin Army, while the rest of the troops were still on the road. Long Tianyu observed the stars for a while, and realized that the army had broken through to Venus, and that the army had gone on to Humen Tan Lang to move.

Long Tianyu sighed inwardly that the time was ripe, because tomorrow, over twenty days, there would be a torrential rain and they would have to travel far to support the Qin Soldier, but due to the rain, they would be forced to delay their journey. According to the laws of the Great Qin, if they did not complete their mission within a set period of time, they would be executed regardless of the original reason. In addition, the green dragon had already been sewn. It was the perfect time for it to appear on a rainy night. Naturally, the commoners could not see the flaws in it clearly.

Three days later, at night, Long Tianyu sent people to gather all of Pei County's family and village in the plaza. Due to the constant rain, the torches were extinguished too, leaving only the sound of thunder and lightning in the dark sky, which was led to the land by the lightning needles that were set up by Long Tianyu in advance.

Long Tianyu was like the director of the advertisement. When the lights, sound effects and scenes were at their best, he instructed Xiahou Ying to lie on the circular "chassis" under the green dragon that was filled with steam. With the help of Guan Ying and Fan Kuai, he pushed the green dragon from the eastern hill of Pei County to the sky.

Xiahou Ying was trembling in fear, ever since he was young, he had never played with such an exciting game, he was more excited than nervous, following Long Tianyu's instructions, he maintained his pressure and buoyancy, and changed the direction of the green dragon hot air balloon, flying towards the plaza.

Long Tianyu stood on the parade platform in front of the plaza and faced the tens of thousands of citizens, and spoke in an imposing manner: "The King of Qin was once blessed by the heavens for winning the battle, but was ordered by the heavens to unite the six nations. He went against the will of the heavens, fell from power, went on a rampage, and extravagantly sought to make the people of the world burn in flames.

However, last night, when I woke up, I saw a green dragon floating on a beam. It said that Qin was violating the heavens, and wanted to help me defy the heavens, so that Tian Yu could gather all of the fellow villagers to come today to verify what had happened. It said that we could work together to defeat Qin.

As soon as his voice fell, just as everyone was beginning to doubt his words, the dark clouds in the sky began to churn. A few streaks of lightning streaked across the sky and were directed to their surroundings, borrowing the lightning and flames to see an azure dragon appear over a hundred meters above them. They circled and danced.

Tens of thousands of people looked up at the green dragon flying in the sky in a flash, they were stunned, then Xiao He suddenly shouted: "The green dragon has appeared, Tyrant Qin Bi Wang." Then he knelt down. Everyone was intimidated by the scene before them and knelt down as well.

Long Tianyu took the chance and aimed the high tech gold watch on his wrist at the dragon's body, spinning and twisting it, with a swoosh, a thread wrapped around the green dragon hook, and his entire body was pulled by the watch, and immediately flew into the air.

When he neared the dragon's body, he somersaulted and leapt onto the green dragon's back, turning into the scene where he was riding on a green dragon and dancing. This time, forget about ordinary people, even, Lv Zhi, Lv Chen who had planned beforehand didn't know how Long Tianyu was able to fly onto the dragon's body.

Xiao He shouted again, "The birth of the son of the true dragon and the death of him are just around the corner."

The tens of thousands of terrified citizens followed suit and shouted. Riding on the dragon's back, Long Tianyu read out the ten great sins of Hu Hai II and the imperial court, calling on the people to carry out the revolution to the end and bring the situation to its climax.

Using the same method as the watch, he returned to the ground and retrieved the alloy wire. Xiahou Ying controlled the steam equipment and followed the same route to the top of the mountain.

Tens of thousands of people were so frightened by the scene of the thunder and the green dragon flying around that they didn't see any flaws at all. Moreover, it was difficult to find any flaws in the dark night under the rain.

called the names of the troops "Dragon Army" and split them into four groups of a thousand people each. Each team was led by the father and son of the Lv Chen, Cao Can, Guan Ying and her son, Xiahou Ying and Fan Kuai. As for Xiahou Ying, he was still in charge of fighting against the Qin elites.
