"How high can you fly?"

Hearing the young master's words, someone asked curiously.

Li Zhao thought for a while and said casually: "It should be up to hundreds of zhang." "In his previous life, he didn't have much research on hot air balloons, but he had also heard of approximate numbers, and I heard that he could fly more than a thousand meters, which can be summarized by hundreds of zhang.

This is just the number he said to Shaoli, but it stunned everyone.

Flying hundreds of feet in the sky, this is simply terrifying, and even big birds can't fly that high.

But the ensuing scene confirmed that statement.

I saw that the hot air balloon carrying no fist flew higher and higher, and finally turned into a black dot, slowly moving forward, and finally disappeared.

This height should be in the hundreds of zhang.

"Sure enough, the things that the young master took out are so amazing."

Someone couldn't help but pat themselves on the back.

Li Zhao just smiled faintly, and said: "Everyone has seen it, this is a hot air balloon, there is a button on the hot air balloon, as long as the fire is controlled, the hot air balloon can be lifted and lowered." ”

He also told him the method of controlling the lifting without fists just now.

"You say you can fight in the air with this thing on board?"

Looking at everyone, some people immediately realized that they suddenly realized: "What the young master said is that let's carry a hot air balloon in the air and drop a big killing weapon on the Qin army?" ”

The weapon of mass destruction he mentioned was naturally a grenade, and you must know that some people came from Chang'an Township and had thrown grenades.

Li Zhao nodded with a smile and said, "However, if the grenade falls in the air, if it falls in the Qin army, what do you think will be the result?" ”

Everyone fell into deep thought, if a grenade was dropped above the Qin army, what would happen to the Qin army? They don't have to think about it to know the outcome.

"The Qin army will definitely suffer heavy losses, of course, they will also take counterattacks, but what if the altitude of the flight is raised to hundreds of zhang?"

The crowd was ecstatic, and when it rose to hundreds of zhang, the weapons of the Qin army were out of reach, and they could still throw grenades, isn't this a unilateral massacre?

As for the Qin army's strong crossbow, Wuquan once told them that the range of the stronger Qin Lu is only 600 steps, about 200 zhang, as long as the flight altitude exceeds 200 zhang, then the Qin army will have nothing to do with them.

Not to mention that hot air balloons can fly even higher.

"Young master, we will not disappoint you, and we vow to kill Qin Jun without leaving a single piece of armor."

The confidence of hundreds of people climbed to the peak, and suddenly a strong morale rose, and that momentum was beyond the reach of even ten thousand troops.

"Okay, very good, now you can get acquainted with the hot air balloon, and soon I will order someone to send grenades, so you can get ready for battle!" As long as the Qin army dares to attack my Shanglin Yuan, let them have no return. ”

By now, Li Zhao no longer cared about the life or death of the Qin army, even if some of them were comrades who had fought with him.

"I will not disappoint the young master."

Subsequently, Li Zhao re-explained the operation method of the hot air balloon to everyone and demonstrated it to them in person.

The operation of the heat-gas engine was not difficult, and in less than a quarter of an hour they understood it and began to operate it on their own, some of them ascended to heaven crookedly, others steadily, slowly manipulated, and tried to test the weight they could carry, which did not affect the ascension to heaven or the number of grenades.

This is the key issue, Li Zhao also emphasized it just now, and told them to pay attention to the direction of the wind, otherwise they will not know where they will drift.

In general, the direction of the wind determines the direction of the balloon's flight, but it can also be controlled.

In his previous life, he had a rough understanding of some meteorological knowledge, the air in the sky is layered, and the wind direction of different layers is also different, for example, the south wind blows at an altitude of 300 to 500 meters, and the wind blowing at 500 to 700 is not necessarily a south wind, it may be a north wind.

With such knowledge, it is not difficult to control the flight direction of the hot air balloon, and the ascent and descent will change the direction of flight.

But the problem is that I don't know how long I have to fly in the sky, and if there is no firepower in the middle, then it will be a big problem, so Li Zhao also bought some fuel from the department store in case of emergency.

When everyone was manipulating, they faintly saw that the black dot was back, naturally there was no fist, he disappeared for a while, and he was able to grope his way back, which was really worthy of being a person who had marched.

Of course, if Li Zhao hadn't instilled a little flight knowledge in him in advance, I'm afraid he might not have been able to come back, and I'm afraid he wouldn't know where he would have flown there.

However, even if the black dots were seen, it took a long time for the fistless to go around and around before it landed on the proving ground.

This back and forth made him both excited and a little frightened.

Flying too high, he was at a loss, but fortunately, he tried it in advance, so that he could pass on his experience to a hundred people, and he would not be inaccurate in the battle and affect the battle situation.

Li Zhao didn't need to worry about things here, he had more important things to do, and that was grenades.

The grenade is detonated by a fuse, and the length of the fuse determines the time of explosion, and the current lead is based on the distance on the ground, which is not suitable for aerial throwing.

He had to ask Ah Chao to calculate how long the lead could be thrown at a height of hundreds of zhang and just fall into the Qin army and explode, and he also had to calculate the impact of the wind speed and direction on the grenade, so that he could make the best lead accurately.

However, when he was about to leave, Wuquan brought bad news, he saw in the air that the Qin army had surrounded Shanglin Yuan, it was estimated that it was just three miles away, and a lot of artillery could be seen in the haze, estimated to be thousands.

"Thousands?"

Li Zhao was not surprised that the Qin army had surrounded Shanglin Yuan, but what was unexpected was that there were still thousands of their artillery, you must know that Zhang Han also led the prisoner army to Hangu Pass, and the artillery he carried must not be less, there are still thousands at this moment, he can't guess how many artillery pieces Xiang Gong has sent.

If there were more, it would be difficult to deal with it, and he didn't want to give all his savings over the years to the department store in order to deal with Xiang Gong.

I don't want to go back to the pre-liberation period overnight.

"I know, you immediately let everyone get familiar with the hot air balloon in the shortest possible time, and wait for my order."

Li Zhao's face became solemn, and Wuquan also knew that the young master might think of something bad, so he immediately agreed, and did not dare to slack off at all to urge everyone to familiarize themselves with the hot air balloon.

Li Zhao did not return to Li's mansion, but looked for someone to find Ah Chao, and he wanted Ah Chao to modify the grenade lead, so that he could not only prevent the wind but also grasp the throwing distance.

"Young master, don't worry, Ah Chao will not let you down."

With the development of Shanglinyuan Academy, there have been many mathematical talents, and it is not difficult to calculate these things, and the craftsmen under Ah Chao are so versatile that they should not be difficult for them.

"If it's fast, it has to be done within three days."

Three days, it also seemed urgent, the Qin army did not know when to launch an attack, if it was impossible to conduct air operations within three days, he was afraid that Shanglin Yuan would have some losses.

"No problem!"

"Also, build five more sniper rifles, and bring them in three days."

Ten sniper rifles were taken away by snipers trained without fists, and now the situation is critical, and some more have to be made, this is a last resort, such as the decline of the forest garden, the decapitation operation will come in handy.

Ah Chao swore and swore that he would leave soon.

Li Zhao was not idle, and after inspecting the city wall, he walked to the assembly place of a thousand elites.

For the remaining 1,000 elites, he has to make reasonable arrangements.
