"Enemy Attack ——!"

Suddenly, in the camp of the Wu army, the sentry sounded a sharp scream.

An arrow fired, a bloody glow, and the sentry's screams came to an abrupt end.

Immediately after, hundreds of gunpowder arrows flew and fell into the camp of the Wu army, exploding in an instant.

The power of these gunpowder arrows far exceeded that of previous rocket arrows.

A small powder tube is added to the arrow, which has its own jet thrust, and the range is extremely long, two or three times that of ordinary arrows, and it can also explode.

Although gunpowder arrows are not accurate, they are used to shoot large tents, and they do not need to be accurate at all.

Suddenly, in the depths of the camp, a raging flame burned, and dozens of tents were burned.

The soldiers in the tent of the Wu army's camp were awakened by the sound of the explosion, woke up from their sleep, armed with swords, guns and wooden shields, and rushed out of the camp in terror, ready to fight.

However, there was no sign of the enemy, who only shot arrows from a distance and did not enter the camp.

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

There was a campfire in the camp, and they could see it clearly within a few feet of it. But when I got out of the camp, it was pitch black outside, and I couldn't see anyone, and I didn't know how many enemies there were.

"Night Raid ——!"

"Revenge ——, King! The baggage battalion in the northeast corner of us was attacked by night and suffered heavy losses. Tens of thousands of catties of grain and grass were lost. ”

"Newspaper, my lord! The camp in the southwest corner was attacked by the enemy and hundreds of tents were burned! Hundreds of people were killed and wounded. ”

"Report, my lord, our army's horse battalion has been impacted, and hundreds of war horses have been killed and wounded."

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

These emergencies occurred almost simultaneously. And it was at all the edges and corners of the Wu army, breaking out at the same time.

The scale is not very large, and the enemy troops that attack each place are estimated to be only a few hundred. They released gunpowder arrows, sneaked up and ran away, and did not rush into the camp of the Wu army to fight a tough battle.

Not even a single enemy could be killed.

"Damn~!"

"Command all the 10,000-strong battalions, and the generals will hold on to their places and not retreat!"

Xiang Bi's forehead was bruised, but he couldn't deal with it.

The 250,000 troops of the Wu army are very large, once camped, this camp stretches for more than ten miles, and the war horses alone have to run for a quarter of an hour, and it is difficult to convey the news up and down in time.

A battalion of 10,000 people needs about a mile to be stationed.

When King Wu gave the order, it would take a quarter of an hour before it could reach the place where he was.

By the time the order arrived, the battle would have been over long ago.

It all relied on the Wu army's 10,000-strong battalions to defend itself.

All the generals of the Wu army were anxious, and they called up the sleeping soldiers to prepare for a night attack.

How many enemy troops were there in the night attack?

From which direction?

No one knows, so they can only guard it tightly.

Until dawn.

The sun rises in the east and illuminates the earth.

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

The entire Wu army, with more than 200,000 troops, stayed up all night, guarding their camps, unable to rest, their expressions were tense, and they stayed up all night, and they were exhausted.

In the morning.

The whole army of Wu slept and stopped attacking Wanling City.

...

"Reinforcements from the imperial court have finally arrived!"

"There must be an imperial army that pinned down the Wu army on the periphery and attacked the Wu army camp at night."

"The 250,000 battalion of the Wu army has been working all night, and it must be exhausted, how can it have the energy to fight during the day?"

Xie Anran, Princess Xiang Ling, and all the generals were in Wanling City, watching the riots in the Wu army camp for a night, and they were all ecstatic.

Although I don't know who came.

But it must be the army of the imperial court.

Reinforcements from the imperial court came, giving them hope to hold on.

"Since the Wu army has stopped attacking the city, let the soldiers hurry up and rest!"

Xie Anran ordered.

The soldiers of Wanling City finally got a short rest, and they all hugged their swords and guns, and buried their heads on the city wall and slept.

...

Afternoon.

King Wu woke up, and the Wu army was full of food and drink, and began to siege the city.

This battle was fought until dusk.

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

King Wu and all the generals almost all realized that the mysterious enemy army last night would definitely come to attack at night again.

They had to think of a plan to guard against the night attack of this enemy army.

...

Sunset.

A light cavalry of 1,000 people, dressed in black, quietly appeared a few miles away from the Wu army's camp.

Chu Tianxiu, Li Yu, as well as Di'er, Zu'er, and hundreds of Li family children, plus cavalry who were carefully selected from 20,000 cavalry without night blindness.

Enough 1,000 light cavalry without night blindness were gathered to form a small "night raid battalion".

Nyctalopia.

Because of the lack of vitamin A, the retina is deficient in photoreceptors, and once the light becomes weak, it will be blurry and unable to distinguish objects, resulting in night blindness.

It is normal during the day, but once the night is in a low-light environment, even if the sky is full of stars, you can't see your fingers, even if you hold a torch, the distance is a little farther.

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

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

In ancient times, the poor could hardly eat meat. Carrots are still being cultivated in Afghanistan and are usually introduced to China from Iran after about a thousand years.

However, not many wealthy people in ancient times suffered from night blindness. Because their food, pig liver, chicken liver, etc., are more common, and they have been eaten since childhood, and they have enough vitamin A.

The concept of vitamins was not clear to the ancients.

Most of them don't know why they get night blindness or how to avoid it. ... Even if you know, the poor can't afford to eat meat all year round.

Of course, Chu Tianxiu knew it very well.

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

Hundreds of children of the Li family, as well as hundreds of well-born children of the Shi clan selected from the 20,000 light cavalry, none of them had night blindness.

These selected rich disciples ensure that eating a piece of chicken liver is enough to maintain night vision, and as long as there is a faint light, they can see far away.

However, it is still difficult to organize a large-scale night battle by simply selecting a few soldiers who do not have night blindness.

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

The command of the army depends on the eyes of the soldiers, who follow the flag. Or the sound of gongs and drums.

Once the generals and soldiers are separated by a hundred meters, they still can't see each other clearly, and they can't pass messages to each other in time except by shouting.

The battlefield is noisy, and the shouting effect is weak.

These soldiers are only suitable for small forces, and it is difficult to form a large-scale army to carry out night raids.

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

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

In the past few days, Chu Tianxiu's 50,000 troops have stayed in Danyang County, of course, they have not been idle. It was to set up a "night owl battalion" to prepare for the night attack on the Wu army.

In order to maintain the speed of the night attack, the night owl battalion was full of light cavalry.

A thousand hussars without night blindness were selected and each of them was tied to a low-light fluorescent ribbon on their shoulders - so that they could see each other's ranks.

They were given a large number of different fireworks as signals, and agreed on "attack, retreat, call for help, transfer, assemble...", etc., in different colors and quantities.

Let all the hussars remember.

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

In an instant, all the hussars were given orders to attack and retreat.

The effect of this kind of command is far more effective than shouting, flags, gongs and drums, and so on.

At night, there was hardly anything else that could be delivered to all the hussars faster than fireworks.

In this way, the command ability of night raid operations has been greatly enhanced.

Chu Tianxiu also prepared a batch of "gunpowder arrows" transported from Jinling City for this night owl battalion. The thrust of the powder tube can increase the range of the arrow by two or three times.

The bonfires, fences, and horse repulsion guards of the Wu army on the periphery can block about fifty paces at most.

You must know that the Wu army camp of 10,000 people is only one mile round.

The range of gunpowder arrows was as high as more than 300 paces, almost half a mile away, and they shot directly into the center of the Wu army's camp, exploding and burning.

Raid the camp!

Of course, it was to attack the camp of the Wu army, burn down all the camp tents, and burn a large amount of baggage, grain and grass carried by the Wu army, creating a huge chaos.

With 1,000 light cavalry without night blindness, using fireworks to command, and carrying gunpowder extended-range arrows, these three sharp weapons combined, the combat effectiveness of the "Night Owl Battalion" was simply too strong to be terrifying, and even the 200,000 troops of Wu's army were terrified.

Last night, Chu Tianxiu and Li Yu, with a thousand light cavalry attacking the camp at night, harassed the periphery of the Wu army, just to test their skills and verify whether the fighting style of the night battle is reliable.

Tonight, Chu Tianxiu and Li Yu led the night owl battalion to appear outside the Wu army camp again, but they were preparing to carry out a larger-scale attack.
