That is to say, it is reasonable to clear the flammable materials a little later even if the treatment is completed.
The reason is that it is very difficult to attack with fire in this era.
There was no such thing as gasoline or kerosene in the Qin Dynasty.
Ordinary people basically use pine tree oil for lighting.
Rich people use animal fat called "paste".
Resin burning produces heavy black smoke and odor, compared with animal fat, it is much better.
If you had more money, you would add spices to animal fat.
Light it up to bring out a little fragrance, which is a great enjoyment.
This is the "orchid paste and bright candle" mentioned in Chu Ci.
However, whether it is rosin or ointment, or ointment with spices added.
It is even more difficult to rely on them to set fire to enemy castles.
Among them, the ointment is still very limited.
People in the Qin Dynasty lived in poverty and had little meat to eat, and of course there was not much animal fat.
Therefore, the fire attacks of this era mostly used rosin.
Tie a ball of hemp rope or linen cloth with rosin on the front end of the arrow cluster.
After being ignited, thousands of arrows were fired... and then balls of flames went straight towards the enemy camp.
This kind of fire attack can also be used to ignite tents, thatch or houses.
If you want to set the walled city on fire, you absolutely cannot.
Because the entire log was used to build the walled city, even if the rocket was firmly nailed to it and burned to ashes, it would have no impact at all.
What's more, Zhao Jun is not a fool. He can be extinguished by just pouring down a basin of water or a bucket of sand.
As for using the trebuchet...
Before Shen Bing improved the trebuchet, its range was only a hundred steps.
Attack with trebuchet fire?
Do you still want to die?
If the enemy rains arrows at the right time and prevents the fire bombs from being fired, wouldn't it mean that you will be burned?
This is why Yang Ting and Tian were asked in unison when they heard Shen Bing talking about fire attack:
"What can we use if we don't have rockets?"
"Use a trebuchet!" Shen Bing answered without thinking.
"Trebuchet?" Yang Ting and Tian thought it was impossible at first.
But when she thought about it, Yang Ting clapped her hands excitedly and said:
"Hold on!"
"The trebuchet has been improved several times and its range is more than twice that of the old trebuchet."
"Why not use a trebuchet to throw fire bombs?"
"That's not comparable to the rocket's ignition head!"
Tian Qui is still a little worried:
"It's a good plan though."
"But Zhao Jun is at a high place, and their trebuchets have also been improved."
"If Zhao Jun also builds many trebuchets, I'm afraid..."
This worry is not entirely unreasonable.
Zhao Jun stood on Woniu Mountain, its height was even higher than that of the Great Wall.
Although there is still a generation gap between the trebuchets of the Qin and Zhao armies under the influence of Shen Bing, the difference in range is no longer large.
This gap can be completely made up by the height difference.
Therefore, as long as the Zhao army has enough trebuchets, the Qin army's trebuchets will be difficult to get close to them in the rain of bullets.
Even if it gets close, it may not be able to fire a few fireballs before it is destroyed.
Then, like before, the fire attack will fail and burn itself instead.
But this problem is easy to solve, at least it is not difficult for Shen Bing.
Shen Bing raised his head and said, "Can't we just take advantage of the darkness to attack?"
Tian was stunned on the spot.
Keep it!
In the darkness, the enemy could not stop the Qin army's trebuchets from approaching.
Even before the Qin army ignited the fireball, Zhao Jun was probably unable to determine the location of the Qin army's trebuchet.
Even if the position was determined, Zhao Jun could not correct the impact point after launching the stone projectile because he could not see the impact point.
On the contrary, the Qin army could adjust calmly.
Thinking of this, Tian was cursed in his heart:
"Why can't you think of such a simple truth?"
"But let this little soldier point him out."
"Where can I put the face of my two to five hundred masters?"
If Shen Bing knew what Tian Suo was thinking, he would probably be shocked.
Tian Bei actually knows the principle of trebuchet calibration?
Yang Ting didn't know why, she asked with a confused face:
"Why is a night attack beneficial to our army?"
Shen Bing explained:
"It's just because our army's trebuchets shoot fire bombs."
"The fire bomb means our troops can clearly watch it being fired at the enemy."
"It is also clear whether the projectile is close or far from the target, so our army can adjust the distance or correct the weight."
"And Zhao Jun..."
Yang Ting couldn't help but be overjoyed when she heard this. She continued what Shen Bing said:
"But the Zhao army fired stone bullets."
"They had no way of knowing in the dark whether the stone was near or far from the target."
"Therefore, there is no way to adjust or correct, and we can only hit it randomly."
Shen Bing cupped his hands and replied: "The captain is wise, that's exactly what it is."
Yang Ting was stunned for a moment.
Talent, proper talent!
Not only can he improve the trebuchet, but he also knows how to use it skillfully.
Not only do you know how to use it skillfully, but you also know how to exploit your strengths and avoid weaknesses...
The enemy also has trebuchets, which are also improved and occupy the best position.
It was originally a big trouble, but in his hands it disappeared with just a gesture.
Even if Sun Wu is reborn, Wu Qi's reincarnation will be nothing more than this!
…
Tian was very unhappy when he saw Yang Ting staring at Shen Bing with her eyes shining brightly, so he let out a "hmm".
Yang Ting suddenly woke up, looked around awkwardly, cleared her throat pretendingly, and ordered:
"A brilliant plan, it is indeed a brilliant plan!"
"We will act according to this plan."
"Master Twenty-Five Hundred, you must fully cooperate with the artillery division to make trebuchets and stone bombs."
"Two days later, we will attack Woniu Mountain at night and burn Zhao camp down!"
Tian Bei and Shen Bing answered at the same time: "No".
Shen Bing didn't feel much because it was not the first time for him to be reused to this extent.
However, Tian Fei felt very uncomfortable in his heart.
Because he knew that Yang Ting's so-called "full cooperation with the gunner" just now was just to give him face.
Its true meaning should be "fully cooperate with Shen Bing".
Why do you want a master of two to five hundred to cooperate with a warrior?
Let a government official cooperate with a civil servant?
Tian Bei couldn't swallow this breath no matter what.
What made Tian Ban even more angry was the way Yang Ting looked at Shen Bing.
I miss my field to be a talented person, wise and mighty, cool and suave... Alas!
Tian Fei sighed heavily in his heart.
In fact, Tian Bao has admired Yang Ting for many years, but he never dared to speak because of his humble status.
Therefore, Tian Bei has been trying his best to gain credit over the years, hoping that one day he will be able to win a beautiful woman.
Unexpectedly... the other party is just a public servant, a public servant! A public servant!
"Two to five hundred masters?" Yang Ting saw Tian Fei's expression was different and asked, "Do you still have any objections?"
"No objection." Tian was quick to reply: "My subordinates resign!"
Before leaving, he didn't forget to glare at Shen Bing.
Shen Bing didn't notice this.
Just kidding, all he can think about is this battle.
This is going to end up being shrouded in horse leather at every turn. Who would care about jealousy in a life-or-death situation? Their brains are almost flooded.
However, just because Shen Bing thinks so does not mean that others will think so.
If you show too much edge, you will always be hated by others.
Especially the personal relationship between children, and the personal relationship between children who are in a weak position and have low self-esteem...it is easy for people to get into trouble and do stupid things.
But Shen Bing only had enemies in his eyes.
He didn't realize at all that danger was quietly approaching him.
