Daqin Engineers

In fact, Xuchang used such a sloppy way.

That is to say, it is excusable to clear the combustibles for a period of time even if the treatment is completed.

The reason is that it is very difficult to attack by fire in this era.

There was nothing like gasoline or kerosene in Qin Shi.

Ordinary people basically use pine grease for lighting.

Rich people use animal fats called "cream".

The resin burns with heavy black smoke and peculiar smell, compared with animal fats and oils is much better.

If you have more money, you will add spices to animal fats.

Light it up to bring out a little scent, it is a great enjoyment.

This is the "Lan Gao Ming Zhu" in Chu Ci.

However, whether it is pine resin or ointment, or a perfumed ointment.

It is even more difficult to rely on them to set fire to the enemy's city.

Among them, the cream is still very limited.

People in Qin Shi had little meat in their lives, and of course there was not much animal fat.

Therefore, the fire attack of this era is more to use rosin.

Tie a bunch of turpentine rope or linen to the front of the arrow cluster.

After being ignited, ten thousand arrows were fired... so the flames went straight to the enemy camp.

It is possible that this fire attack is used to light tents, thatchs or houses.

Want to ignite the walled city is absolutely impossible.

Because the whole log is used to build the walled city, even if the rocket is firmly nailed to it and burned to ashes, it will not affect it at all.

What's more, Zhao Jun is not a fool, he can pour out a pot of water or a bucket of sand.

As for the trebuchet...

Before Shen Bing improved the trebuchet, its range was less than a hundred steps.

Fire attack with a trebuchet?

Do you want to die?

If the enemy rained down at the right time and prevented the fire bombs from launching, wouldn't it burn yourself?

This is also why Yang Ting and Tian would ask in unison when they heard Shen Bing said Huo Gong:

"What can I use without a rocket?"

"Use a trebuchet!" Shen Bing answered without thinking.

"Catapult?" Yang Ting and Tian felt impossible at first.

But looking back, Yang Ting clapped her hands excitedly and said:

"Hey!"

"The range of the trebuchet after several improvements is more than twice that of the old trebuchet."

"Why not use trebuchets to throw fire bombs?"

"That's not comparable to the rocket's ignition head!"

Tian Bei is still a little worried:

"Thoughts are good ones."

"But Zhao Jun is at a high place, and their trebuchets have also been improved."

"If Zhao Jun also built many trebuchets, I'm afraid..."

This worry is not entirely unreasonable.

Zhao Jun stood on Wo Niu Mountain, and its height was even higher than that of the Great Wall.

Although the trebuchets of the Qin and Zhao armies still have a generation gap under the influence of Shen Bing, the range difference is not large.

And this gap can be made up by the height difference.

So as long as Zhao Jun had enough trebuchets, Qin Jun’s trebuchets were afraid it would be difficult to get close in the rain of bullets.

Even if you get close, you may not be able to fire a few fireballs before being destroyed.

As a result, he would burn himself out of the fire like before.

But this problem is easy to solve, at least not difficult for Shen Bing.

Shen Bing raised his head and said, "Will I wait for the attack by night?"

Tian was dumbfounded on the spot.

Come on!

The enemy could not stop the Qin Jun trebuchet from getting close in the night.

Even before Qin Jun lit the fireball, Zhao Jun was afraid that he could not determine the location of Qin Jun's catapult.

Even if the location was determined, Zhao Jun could not correct it because he couldn't see the impact point after launching the stone bullet.

On the contrary, the Qin Army can calmly adjust.

Thinking of this, Tian was cursed in his heart:

"Why can't you think of such a simple reason?"

"But let this little soldier point it out."

"Where is the face of my two or five hundred masters?"

If Shen Bing knew what Tian Bei was thinking in his heart, I'm afraid he would be shocked.

This field actually knows the truth of trebuchet correction?

Yang Ting shouldn't be unaware, so she asked blankly:

"Why is the night attack beneficial to our army?"

Shen Bing explained:

"It's just because our trebuchets hit fire bombs."

"Fire bomb means that our army can clearly watch it shoot at the enemy."

"It's also clear whether the fire bomb is near or far away from the target, so our army can adjust the distance or adjust the counterweight."

"And Zhao Jun..."

Yang Ting couldn't help being overjoyed when she heard that, she continued Shen Bing's words:

"But Zhao Jun hit stone bullets."

"They have no way of knowing whether the stone bullet is near or far from the target in the dark."

"Therefore, there is no adjustment and no correction, only a slap in the face."

Shen Bing replied: "School Wei is wise, that's the case."

Yang Ting was stunned for a while.

Talent, proper talent!

Not only will it improve the trebuchet but also know how to use it.

Not only know how to use it, but also know how to use one's strengths and avoid weaknesses...

The enemy also has trebuchets, which are also improved, and take advantage of the land.

It was a big trouble, but in his hands it was just a gesture and it was wiped out.

Even if Sun Wu reincarnated and Wu Qi reincarnated, it was nothing more than that!

...

Tian was very unhappy when he saw Yang Ting staring at Shen Bing with bright eyes, so he let out a "huh".

Yang Ting suddenly woke up, looked around awkwardly, cleared her throat pretendingly, and ordered:

"A trick, it really is a trick!"

"I will act on this plan when I wait."

"Two or five hundred masters, you must fully cooperate with the artillery to make catapults and stone bullets."

"Two days later, we will attack Wo Niu Mountain at night, let's burn Zhao Ying!"

Tian Bei and Shen Bing replied: "No."

Shen Bing didn't feel anything, because this level of reuse was not the first time for him.

However, Tian Bei was very unhappy in his heart.

Because he knew that Yang Ting's so-called "cooperating fully with the artillery" just now was just to give him face.

Its true meaning should be "to cooperate fully with Shen Bing".

What is the special way for a two-to-five hundred master to cooperate with a warrior?

Let an official doctor cooperate with a servant?

Tian Bei couldn't swallow this breath.

What made Tian Bei angry even more was Yang Ting's look at Shen Bing.

I think we are a talented person, wise and martial, chic and suave... alas!

Tian Bei sighed heavily in his heart.

In fact, Tian Bei has admired Yang Ting for many years, but because of his humble status, he has never dared to speak.

So Tian has been trying his best for all these years, only hoping that one day he can be a beautiful woman.

Unexpectedly... the other party is just a servant, a servant!Gongshi!

"Two or five hundred masters?" Yang Ting saw that Tian Bei's expression was different, and asked, "Are there any objections?"

"No objection." Tian Bei hurriedly replied: "Subordinates retire!"

Before leaving, he did not forget to give Shen Bing a glance.

Shen Bing did not notice these.

Just kidding, his head is full of this battle.

This motionlessness is for the shroud of horse leather. Who cares about the jealous thing at the moment of life and death, his mind is almost flooded.

However, Shen Bing's thinking does not mean that others will also think so.

Being too sharp is always jealous.

Especially children's personal relationships, children who are in a weak and inferiority state...It is easy for people to get into the horns and do stupid things.

But Shen Bing had only enemies in his eyes.

He didn't realize the danger was coming towards him quietly.
