It is different from the Han Dynasty, which has been passed down for 400 years. Xianbei was a loose tribal alliance that failed to form a complete system of government. The weak eat the strong, plundering for a living. They also fought with each other. Tanshi Huai generation of male masters, the southern expedition and the northern war to dominate the grassland. It seems to be strong, but it has no foundation.

If he dies, he will be in chaos.

The position of the big single will be coveted by countless people.

Just as Liu Bei's Northern Expedition was the Han Dynasty's prestige for four hundred years. Tan Shihuai personally commanded an army of 100,000 to besiege the city, and lost his troops. There are many dissatisfactions left and right. So he planned to borrow Liu Bei's knife to kill the three Xianbei adults who had different hearts.

The reasons are all the same.

But is that really the case?

Tanshi Huai was infected with an incurable disease and died soon. The only son was beheaded by Liu Bei in the king's tent. Now he is alone, alone. Even if you can sit firmly on the throne, what good is it?

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

With such a heart, how can he dominate Xianbei and claim to be the hero?

seemed to be a flawless answer, but the more Liu Bei thought about it, the more he felt that it was wrong. There must be a hidden secret. When I looked up again, I saw that Da Yan's face was expressionless, without joy or sorrow. Liu Bei sighed, forget it, he is not the master of the strong.

Six days.

Xianbei came to attack the city again.

Although the head of the city still shoots arrows, it is much more sparse than in previous days. The powerful bed crossbow and the yellow crossbow are nowhere to be seen. Xianbei stepped on the corpses of people and horses and crossed the river easily. Rushing to the city wall, the stones and logs rolled down. The Xianbei elite soldiers, who had no siege equipment, looked at the wall and sighed. His brain burst and he died a tragic death.

There are many corpses under the wall. Then the Xianbei warriors carried them together, piled them up into mounds, and climbed towards the city.

Fish oil and firewood were poured on the wall. Shoot down the rocket. A fire broke out in the pile of corpses. Engulf nearby sergeants. The flames spread. Around the city walls, piles of flames rose. The smoke was so thick that I couldn't see it. The Xianbei warriors under the city were smoky and smoky, and tears flowed. How can you still fight. The defenders at the head of the city, however, had breathing masks that were completely unaffected by the fireworks. The stone smashed down with force, killing countless enemies.

The three Xianbei adults who pressed the formation in the rear looked up at the sky from time to time. Seeing the sun in the sky, it was already fighting until noon. Xianbei Jing rode abandoned horses to attack the city, and many were killed and wounded. This compromise has already touched the foundation. There were scouts last night. The three-way Han army has broken through the blockade and is coming straight to Baitan City. If you don't leave, Xianbei is in danger.

After fighting for a long time, I suddenly heard the thunder of joy ahead!

Then there was a scout report: the front army had breached the drawbridge.

The three Xianbei were ecstatic. Sure enough, the drawbridge fell violently, and the city gate opened.

The doorway is full of clumps of antlers to resist horses. The spears are like a forest, stabbing out from time to time. The Xianbei warrior was hit by several wounds, especially swinging the knife, frantically chopping the giant tree. Tear apart the antlers one by one. The two sides will not budge an inch. It's all hand-to-hand combat. You come and go, swords face each other. There are mutual injuries. The Han army was a pikeman. Attack each other with the Xianbei scimitar and gain the upper hand. Except for being shot by a sneak attack with a bow, it was fine. Rao is like this, and he can't resist the Xianbei dead who are not afraid of death.

And so on and so on and so forth. Leaving behind a place of Xianbei corpses, all the antlers and horses were destroyed.

After occupying the gate of the urn city, the Xianbei dead soldiers did not rush in, but waited in formation.

Behind him, the horse's hooves roared. King Xianbei rode all the way. Rush over the drawbridge and head straight to the urn city!

At this time, the Xianbei dead soldiers rushed into the city one after another to lead the way for the king.

The urn city and the inner city are separated by only one gate. Losing the reliance of the moat, the down-to-earth Xianbei army has too many ways to break through the inner city gate.

In addition, there is a lack of arrows in the city, and there is no fear of raining arrows from the four walls of the urn city.

The pikemen were all on the wall. There is nothing else in the urn city. There were only piles of haystacks, which emitted a pungent smell. Before the Xianbei spirits who filled the urn city could dismount, a rocket shot down from the wall. The haystack burst into blue flames. It's like a ghost fire.

For a moment thick smoke filled the air.

King Xianbei's skin festered and his eyes were bleeding. He was convulsed and suffocated.

The haystack was pre-mixed with sulfur.

Sulfur emits a cyan flame when burned. Sulfide gases are produced, which are absorbed by the moist mucosal surface to form acids. The skin and eyes are easily burned. Large inhalation can cause pulmonary edema, laryngeal edema, vocal cord spasm and suffocation.

The urn city is surrounded by high walls and is not well ventilated. Sulphur fumes gather in it and are extremely concentrated.

The Xianbei King who rushed into the urn city, although he was wearing heavy armor from the Western Regions, he had no breathing mask to resist. Caught off guard, everyone inhaled toxic smoke and suffocated to death.

Killing the enemy with poison gas was not the first initiative of Liu Bei. There are precedents in ancient and modern times, both in China and abroad.

In "Mozi Beixue", there is a detailed record.

There have also been cases abroad. During the Battle of Dura Europs, the Persians also lit sulfur in the tunnels and blew poison gas into the tunnels with wind blasters, poisoning all the Roman soldiers. During the Peloponnesian War, the Spartans also used brimstone to create poison gas to attack the defenders of Athens.

The only difference is that the soldiers under Liu Bei's command have a set of breathing masks. And it is different from the black warrior half-mask that Huang Xu has worn since he was a child. The defenders of Baitan City all wore fully enclosed masks. The eyes are mirrored with casings. In the sulphur smoke, the eyes can also see. Rao is also slightly poisoned. Fortunately, he retreated to the high wall early, and with the help of the wind, he bent down to dodge.

Poisonous smoke gushed out from the doorway. Subsequently, the Xianbei soldiers were poisoned one after another and fell off their horses. For a moment, people turned on their backs. The scene was terrifying.

Even the elite kings who wore turtle chain armor, human and horse equipment, and swords were hard to hurt, also died. Toxic smoke is pervasive. It's hard to guard against armor!

This is Liu Bei's means of defending against the outflow of Lou Sang soldiers and pressing the bottom of the box.

Of course, even Liu Bei was unexpected.

Failed to pinch the dosage, and even overdosed. The smoke soared, and when it was blown by the wind, it rolled back into the inner city!

Fortunately, it was a northwesterly wind. Thick smoke swept through the southeast corner of the inner city. There were no major casualties. If it's a wind coming from the north......

Liu Bei subconsciously shuddered.

Xianbei Zhongjun. The sandalwood locust on the throne had a vicious attack and was in pain.

The ability of the Han army far exceeded expectations. Six days of bloody fighting. Of the 100,000 troops, only six or seven out of ten remained.

The three Xianbei adults are even more resigned.

This Xianbei big single position still needs to be considered in the long run.

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

If it weren't for the urgency of time, only a moat and an urn city would have been built. Tiger falls, horse faces, battlements, moats, thistles, etc., have not all been built. And why do you need to poison it?

Poisonous smoke spreads all over the inside and outside of the urn city, and if you smoke it, you will die. How can you fight? Xianbei had to hastily withdraw his troops.

The three lords gathered in the king's tent and begged to retire.

The sandalwood on the throne, his eyes were like wolves, and after looking around the left and right, he said sharply: Today has broken the urn city, and it is separated from the inner city by one gate. The Han military skills were poor and poisoned, endangering themselves. One more day of fighting, you will be able to win! At that time, the Han army will be slaughtered, and the northern land will be at my disposal. If this battle cannot be won, the loss of troops will be secondary. The prestige of the Han Dynasty was strengthened, and the surrounding Ding Ling, Fuyu, and Wusun were the two native dogs of the Han family, (northern) Xiongnu and Wuhuan, and they would also bare their fangs. The group rises up and attacks, and Xianbei will be destroyed. Our family children and grandchildren, horses, cattle and sheep have all become other people's playthings.

Moreover. At this time, the army was withdrawn, and there were three Han troops blocking the road in front, and there were white sandalwood pursuers in the back. There was a great drought in the grasslands, locust plagues were raging, and not a single grass was grown. Only by staying far away from the desert north can we temporarily avoid the edge. If they did so, the herdsmen and slaves all over the steppe were killed and plundered by the Han army. There are no cattle and sheep for thousands of miles, and the heavy snow is coming, where else can we go to eat?

Seeing that there was no sound on the left and right, the sandalwood acacia was loud: now it has become a tiger riding trend. If you don't fight, you will die. Cowardice will die. If you can't win the war, you will die. Heaven is dead, I am humble. The only way to move forward is to live to die!
