In fact, Xuchang used such a sloppy method.

That is, it is understandable that flammable materials can be cleared for a period of time and the processing is completed.

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

There was no gasoline, kerosene or the like in Qin Dynasty.

Ordinary people's lighting is basically made of pine oil.

Rich families use animal fat called "mouth".

The resin burns with heavy black smoke and odor, which is much better than animal fat.

If you are richer, you will add spices to animal fat.

It will bring out a little fragrance when you light it up, and that will be a great enjoyment.

This is what Chuci calls "orchid orchid cream and candle".

However, whether it is rosin, paste, or paste with spices.

It is even more difficult to rely on them to set fire to ignite enemy cities.

Among them, the paste is still very limited.

In the Qin Dynasty, people had little carnivore in their lives, and of course they did not have much animal fat.

Therefore, the fire attack in this era is more about using rosin.

Tie a ball of hemp rope or linen with rosin on the front end of the arrow cluster.

After igniting, thousands of arrows were fired at once... so balls of flames rushed straight to the enemy camp.

This kind of fire attack is also possible for igniting tents, thatch or houses.

I can't ignite the city.

Because the whole log used to build the city is used to build the city, even if the rocket is firmly nailed to it and burned to ashes, it is afraid it will not have any effect on it.

Besides, Zhao Jun is not a fool. He can just pour a basin of water or a bucket of sand and soil to extinguish it.

As for using a trencher...

Before Shen Bing improved the catapult, its range was only more than a hundred steps.

Use a catapult to fire?

Are you still alive?

If the enemy rains down in time, making the fire bomb unable to be fired, wouldn't it burn yourself?

This is also when Yang Ting and Tian were asked in unison when they heard Shen Bing say that they were attacking fire:

"What can I use without the Rockets?"

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

"Takes?" Yang Ting and Tian felt it was impossible at first.

But when she thought about it, Yang Ting clapped her hands excitedly and said:

"Come on!"

"The range of the catapult has been improved several times is more than twice that of the old catapult."

"Why don't you use a catapult to shoot a fire bomb?"

"That's not comparable to the Rockets' firehead!"

Tian Que is still a little worried:

"Although the plan is a good plan."

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

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

This worry is not completely unreasonable.

The Zhao army stood on Woniu Mountain, and its height was even greater than that of the Great Wall.

Although the catapults of the Qin and Zhao armies still have generation differences under the influence of Shen Bing, the range gap is no longer large.

And this gap can be completely compensated by the height difference.

So as long as the Zhao army had enough catapults, the Qin army would be afraid that it would be difficult for the Qin army to get close to the rain of bullets.

Even if you are close, you may not be able to fire a few fireballs and will be destroyed.

So, as before, the fire attack will burn yourself instead.

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

Shen Bing raised his head and said, "Will we just attack in the night?"

Tian was stunned on the spot.

Come on!

The enemy could not stop the Qin army from scattering in the night.

Even before the Qin army ignited the fireball, the Zhao army was afraid that the position of the Qin army's catapult was not sure.

Even after the location was determined, Zhao Jun fired the stone bomb and could not correct it because he could not see the landing point.

On the contrary, the Qin army could adjust calmly.

Thinking of this, Tian Que cursed in his heart:

"Why would you not think of such a simple truth?"

"But let the soldier point it out."

"Where will my face be placed?"

If Chen Bing knew that Tian was thinking in his heart, he would be shocked by him.

This field actually knows the reason for correcting the catapult?

Yang Ting didn't understand why, she asked blankly:

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

Chen Bing explained:

"It's just because our army's catapults hit a fire bomb."

"The fire bomb means our army can clearly watch it shoot at the enemy."

"And it is clear whether the fire bomb is close 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 but be overjoyed when she heard this. She continued Shen Bing's words:

"And the Zhao army attacked a stone bomb."

"They have no way to know in the dark whether the stone bullet is close to the target."

"So there is no way to adjust and cannot be corrected, so I can only get some fun."

Chen Bing bowed and replied: "The lieutenant is wise, that's exactly what it is."

Yang Ting was stunned for a moment.

Talent, a true talent!

Not only can you improve the catapult, but you can also use it skillfully.

Not only do you know how to use it skillfully, but you also know how to play to your strengths and avoid your weaknesses...

The enemy also has catapults, is also improved, and has a good advantage.

It was originally a big trouble, but in his hands he was wiped out with just a move.

Even if Sun Wu is reborn and Wu Qi is reincarnated, that's it!

...

Tian was very unhappy when he saw Yang Ting staring at Chen Bing with his eyes shining, so he hummed "Hmm".

Yang Ting suddenly woke up, looked around in embarrassment, pretended to clear her throat, and ordered:

"A clever plan is indeed a clever plan!"

"We will act according to this plan."

"Two and five hundred masters, you must cooperate with the artillery master to make trenchers and stone bombs."

"Two days later, attack Woniu Mountain at night, and let's burn Zhao Camp!"

Tian Que and Shen Bing answered in unison: "No".

Chen Bing didn't feel anything, because it was not the first time for him to reuse at this level.
