Unlike the Han Dynasty, which was confucianism outside and law inside, and the counties and states were parallel, and had been passed down for four hundred years. The Xianbei was a loose tribal alliance and failed to form a complete regime system. The strong prey of the weak and plundered for a living. They also fought endlessly with each other. The powerful ruler of Tan Shihuai was fighting south and north to unify the grassland. It seemed strong, but had no foundation.

If he dies, the Xianbei will be in trouble.

The position of the Great Shanyu will be coveted by countless people.

Just as Liu Bei's Northern Expedition was the Han Dynasty for four hundred years. Tan Shihuai personally led a 100,000 army to besiege the city, and lost its troops and generals. Most of them were dissatisfied. So he used the plan and used Liu Bei's sword to kill the three Xianbei people who had already had a strange intention.

All reasons are clear.

But is this really the case?

Tan Shihuai was infected with incurable diseases and her life was not long. Her only son was beheaded by Liu Bei in the tent of the king. Now he is alone and alone. Even if he can sit firmly on the throne of the Great Shanyu of Xianbei, what's the benefit?

It is not good for the country, the family, the others and oneself.

With such a mind, how can we unify the Xianbei and claim to be the dominant leader?

The seemingly perfect answer, but Liu Bei felt the more he thought about it, the more he felt that it was wrong. There must be unknown secrets in it. When he looked up again, he saw that Da Yan had no expression on his face, no joy or sorrow. Liu Bei sighed, forget it, he was not the one who was forced to do anything.

Six days.

The Xianbei will attack the city again.

Although the city still shoots arrows, it is much less sparse than in the previous few days. The powerful crossbows and yellow crossbows are missing. The Xianbei step on the bodies of people and horses and crosses the river easily. They rushed to the edge of the city wall, and stones rolled down the wood. The Xianbei elite soldiers who had no siege equipment sighed at the wall. The brain burst and died tragically.

There were many corpses under the wall. Xianbei warriors moved them together, piled them up into a hill, and climbed towards the city.

Fish oil, firewood, rockets, corpses were shot, and fired fires were burning. The fire spread. Around the city wall, piles of flames rose. Thick smoke soared into the sky, and the eyes couldn't see. The Xianbei warriors under the city were smoky and burst into tears. How could they still fight? The defenders at the city had breathing masks, completely unaffected by fireworks. The stones smashed down and killed countless enemies.

The three Xianbei masters who were in the rear face looked up from time to time. Seeing that Risheng Zhongtian had fought until noon. Xianbei cavalry abandoned their horses to attack the city, with many casualties. Such damage had already touched the foundation. Last night, there were also scouts who reported it. The three Han troops had broken through the blockade and rushed straight to Baitan City. If they did not leave, the Xianbei would be in danger.

After fighting for a long time, I suddenly heard the joy and thunderous sound in front of me!

Then there was a reward from the scout: the front army had broken through the suspension bridge.

The three Xianbei people were ecstatic. As a result, they saw the suspension bridge falling and the city gate opened.

The door hole was filled with clusters of deer antlers resisting horses. The spears were like forests and stabbed out from time to time. The Xianbei warriors were injured several times, especially the swords that kept slashing the giant trees, and they broke up the antlers one by one. Both sides did not give in. They were all close-knit fights. They were fighting each other with swords and swords. They were hurt by each other. The Han army was a spearmen. They attacked each other with Xianbei scimitars and gained the upper hand. Apart from being sneak attacked by the bow, there was no big deal. Even so, they could not resist the Xianbei dead soldiers who were fearless.

In this way, they fought and retreated. The bodies of Xianbei were left behind, and all the deer antlers and horses were destroyed.

After occupying the gate of the urn city, the Xianbei dead soldiers did not rush in, but formed a formation to wait.

The horse's hooves roared behind him. The Xianbei King rode all the way and rushed across the suspension bridge and rushed straight to the urn city!

At this time, the Xianbei dead soldiers rushed into the city to guide the king's cavalry.

The Wengcheng and the inner city are just separated by one gate. Without the support of the moat, the down-to-earth Xianbei army has too many ways to break through the inner city gate.

In addition, there are no arrows in the city, so there is no fear of shooting arrows from all walls of the city.

All the spearmen were on the wall. There was nothing else in the wall. There were only piles of haystacks, emitting a pungent smell. Before the Xianbei spirits who were silted across the wall rode off their horses, rockets shot down the wall. The haystacks actually burst into green flames, like ghost fire.

A moment of thick smoke filled the air.

The Xianbei King's skin was ulcerated, his eyes were bleeding, his whole body was convulsed, and he was suffocated and died.

Sulfur was incorporated into the haystack in advance.

When sulfur burns, it emits a cyan flame. It produces sulfurized gas, which is absorbed by the wet mucosal surface, and forms acid. The skin and eyes are very easy to burn. Inhalation can cause pulmonary edema, laryngeal edema, and vocal cord spasm and cause suffocation.

The walls on all sides of the city are not well ventilated. Sulfur smoke gathers in it, and the concentration is extremely high.

Although the Xianbei King Cavalry who rushed into the city of urn, he was wearing heavy armor in the Western Regions, he had no breathing mask to resist. He caught off guard and all the men and horses inhaled poisonous smoke and died of suffocation.

The poisonous gas killed the enemy was not the first to Liu Bei. There are precedents in ancient and modern times, both in China and abroad.

There are detailed records in "Mozi·Baijiu".

There have been cases abroad. During the Battle of Dura Europus, the Persians also lit sulfur in the tunnel, and used blowing tools to blow poison gas into the tunnel, poisoning all the Roman soldiers. During the Peloponnese War, the Spartan army also used sulfur to create poison gas and attacked the defenders in Athens.

The only difference is that each of the soldiers under Liu Bei's commands has a set of breathing masks. It is also different from the black warrior half mask worn by Huang Xu since childhood. The defenders in Baitan City all wore fully enclosed masks. The eyes were made of casings as mirrors. In the sulfur smoke, the eyes could also see things. Even so, they were slightly poisoned. Fortunately, they retreated to the high wall early, and bent down to avoid them with the help of the wind.

Poisonous smoke gushed out of the door hole. Later, Xianbei soldiers were poisoned and fell off the horse one after another. The scene was extremely terrifying.

Even the elite kings who were wearing Kucha Lock Craft, studded armor, and swords were unable to be injured, were killed one after another. Poison smoke was everywhere. She was wearing armor and was unable to defend herself!

This is a means of Liu Bei defending the outflow of the Sangs and armor from the roof.

Of course, even Liu Bei was unexpected.

I couldn't pinch the correct dosage, and even burned too much. The thick smoke soared upwards, and was blown by the wind, and turned around toward the inner city!

Fortunately, the northwest wind was blowing at this time. The thick smoke passed by the southeast corner of the inner city. No major casualties were caused. If it was the wind from the north...

Liu Bei shivered subconsciously.

Xianbei Central Army. The throne of the tragedy was terrible and was in pain.

The Han army's ability was far beyond expectations. The bloody battle lasted for six days. The army of 100,000 was only six or seven.

The three Xianbei peoples were even more determined to retreat.

The position of the Xianbei Great Chanyu needs to be discussed in a long period of time.

During the first battle to defend the city, Liu Bei also had many shortcomings.

If it were not for the urgency of time, only moats and urns were built. Tiger falls, horse faces, balustrades, moats, caltrops, etc. could not be built in them all. Why should poison be released?

Poisonous smoke spreads inside and outside the city, and if you suck it, you will die. How can you fight? The Xianbei had to withdraw their troops in a hurry.

The three masters gathered in the king's tent and begged to withdraw their troops.

Tan Shihuai on the throne looked like a wolf. After looking around, he said sternly: Today is the city that has been broken, one gate from the inner city. The Han army has poor skills and released poison, and it will almost harm itself. One day, he will be able to win a great victory! At that time, the Han army will be destroyed, and the north will let me gallop. If I cannot win this battle, the loss of troops will be the second. The Han Dynasty is strong and powerful, and the surroundings are Dingling, Wu Yu, Wusun, and two local dogs of the Han family. (South) Xiongnu and Wuhuan will also bare their fangs. When they attack, the Xianbei will be destroyed. Our family, descendants, horses, cattle and sheep will all become other people's belongings.

Besides, when the troops were withdrawn, three Han troops blocked the road in front, and white sandalwood pursued soldiers were clenched behind. The grassland was drought, and locust plague was raging, and no grass was growing. Only by escaping from the north of the desert could we temporarily avoid the edge. If we act like this, all the herdsmen and slaves spreading over the grassland were killed and plundered by the Han army. There were no cattle and sheep thousands of miles away, and heavy snow was coming, where can we go to get food?
