"Enemy attack--!"

Suddenly, the sentry sounded sharply in the Wu army camp.

An arrow shot, and a bloody light shone, and the sentry's scream suddenly stopped.

Following the scene were hundreds of gunpowder arrows flying and falling into the Wu army camp, and exploded instantly.

The power of these gunpowder arrows is far greater than that of previous rocket arrows.

A small gunpowder tube was added to the arrow, with its own jet thrust and a very long range, two or three times that of an ordinary arrow, and it can also explode.

Although gunpowder arrows have no accurate heads, they do not need accurate heads when used to shoot large tents.

Suddenly, deep in the camp, a scattered flames burned, and dozens of camp tents burned.

The soldiers in the Wu army camp tent were awakened by the explosion and woke up from their sleep. They rushed out of the camp in horror with swords, guns, and shields in hand, and prepared to fight.

However, no trace of the enemy was seen. The enemy only shot arrows from afar and did not attack the camp.

The Wu soldiers looked at the dark fields outside the camp, but did not dare to rush in.

There was a bonfire in the camp, and within a few feet of the bonfire, they could see clearly. But after leaving the camp, it was pitch black outside, and there was no one to see, and there were no enemies.

"Night attack--!"

"Report——, King! My baggage battalion in the northeast corner was attacked at night, and the losses were significant. Tens of thousands of kilograms of food and grass were lost."

"Report, King! The camp in the southwest corner was attacked by the enemy, burning hundreds of camp tents! Hundreds of people were killed or injured."

"Report, the king, our army's horse camp was hit, and hundreds of war horses were killed and injured."

Many urgent reports were quickly sent to the camp of the King of Wu.

These emergency military information occurred almost at the same time, and broke out at all edges and corners of the Wu army.

The scale is not very large, and there are probably only a few hundred people in each enemy attack. They set off gunpowder arrows, sneaked into the Wu army camp and ran away, and did not rush into the Wu army camp to fight tough battles.

Even an enemy was unable to kill.

"Damn it~!"

"Appoint each 10,000 battalions to defend the enemy on the spot and not retreat!"

The blue veins on Xiang Bi's forehead swelled up, but he couldn't deal with it.

The 250,000 Wu army was very large. Once camped, the camp would run for more than ten miles, and the war horses alone would run for a quarter of an hour. The news was difficult to convey up and down in time.

A camp of ten thousand people would probably require one mile to be stationed.

The King of Wu issued the order and it would take a full quarter of an hour to reach the place where he was located.

When the order arrives, the battle will be over long ago.

It depends entirely on the Wu army's camps and defending themselves.

The generals of the Wu army were all in a panic and shouted all the soldiers in their sleep, preparing to fight a night attack.

How many enemy troops were attacked at night?

From which direction?

No one knows, so he can only guard against it.

Until dawn.

The sun rises eastward and shines on the earth.

This mysterious night attack army finally retreated silently, leaving no casualties, and disappeared into the wilderness.

The entire Wu army had more than 200,000 troops waiting all night to guard their camps, but they could not get a rest. They looked tense and stayed up all night, and were exhausted.

In the morning.

The entire Wu army went to bed and stopped attacking Wanling City.

...

"The reinforcements from the court have finally arrived!"

"It must be that there was a court army that restrained the Wu army on the periphery and attacked the Wu army camp at night."

"The Wu army's 250,000 battalion was endless all night, and it must be exhausted. How can I have the energy to fight during the day?"

Xie Anran, Princess Xiang Ling and the generals watched the riots in the Wu army camp for a night, all of whom were ecstatic.

Although I don't know who is coming.

But it must be the army of the court.

The reinforcements from the court came, giving them hope to stick to it.

"Since the Wu army has stopped siege, let the soldiers rest quickly!"

Xie Anran ordered.

The soldiers of Wanling City finally got a brief rest, holding swords and guns, burying their heads on the city wall and then sleeping.

...

afternoon.

When the King of Wu woke up, the Wu army had enough food and drink, and began to attack the city.

This battle lasted until dusk.

A few hours later, the Wu army stopped and did not attack the city again.

The King of Wu and the generals were almost enlightened - the mysterious enemy army last night would definitely come again to attack the night.

They have to find a way to guard against the night attack of this enemy army.

...

At sunset.

A light cavalry of a thousand people, wearing black clothes, quietly appeared several miles away from the Wu army camp.

Chu Tianxiu, Li Yu, Di'er, Zuer, and hundreds of Li's children, plus carefully selected cavalrymen without night blindness from 20,000 cavalrymen.

A total of 1,000 light cavalrymen without night blindness were collected and a small-scale "night attack camp" was formed.

Night blindness.

Because of the lack of vitamin A, the retina lacks photosensitive substances. Once the light becomes weak, it will become blurred and cannot distinguish objects, resulting in night blindness.

It is normal during the day. In the low-light environment at night, even if there are stars in the sky, you will not see your fingers. Even if you raise the torch, it will not work even if you have a little distance.

Foods rich in vitamin A are mainly animal liver, cod liver oil, carrots, etc., which can prevent night blindness.

In fact, this night blindness can also be called "poor disease".

In ancient times, the poor people basically couldn't eat meat. Carrots were still grown in Afghanistan, and they were normally introduced from Iran to China about a thousand years later.

However, in ancient times, the rich people did not suffer from night blindness. Because their foods, pork liver, chicken liver, etc. were more common. They were eaten since childhood and had sufficient vitamin A.

The ancients did not know the concept of vitamins.

Most of them don’t know why they get night blindness, nor how to avoid it... Even if they know, the poor can’t afford to eat a meal of meat all year round.

Chu Tianxiu is certainly very clear about it.

Emperor Jinling is the richest and most densely populated place in the world.

Hundreds of Li's children, as well as hundreds of children of good-born families selected from 20,000 light cavalrymen, all of them have no night blindness.

These selected rich disciple soldiers ensure that eating a piece of chicken liver every now and then is enough to maintain night vision. As long as there is faint light, you can see farther places.

However, it is still difficult to organize a large-scale night battle just by selecting some soldiers without night blindness.

Because at night, there is a lack of means to command the army.

The command of the army depends on the eyes of soldiers and follow the flags or the sound of gongs and drums.

Once the generals and soldiers are a hundred meters apart, they still cannot see each other clearly. Apart from shouting, they cannot convey messages to each other in time.

The battlefield is noisy and the shouting effect is weak.

These soldiers are only suitable for small groups of operations, and it is difficult to form a large army to conduct night attacks.

At night, once the general leads his troops out of the camp, he almost completely loses the control of his own army.

Therefore, since ancient times, large-scale night battles have rarely occurred.

Chu Tianxiu has stayed in Danyang County these days, and of course he has not been idle. He has specially formed a "Night Owl Camp" to prepare for the night attack on the Wu army.

In order to maintain the speed of the night attack, the Night Owl Camp was full of light cavalry.

Select a thousand light cavalrymen without night blindness, and let each of them tie a low-light fluorescent ribbon on their shoulders - so that they can see their own teams with each other.

They brought a large number of different fireworks as signals, and agreed on "attack, retreat, seek help, transfer, assemble..." in different colors and quantity.

Let all the light cavalry remember it.

Fireworks rise to the sky and can be seen within four or five miles, or even ten miles.
