The Han army on the top of the city did not protect themselves in advance. When the Wei army suddenly threw lime powder, they could only find a way to protect themselves first.
Unexpectedly, the Wei army took the opportunity to climb the city.
However, Wei Yan was also a veteran on the battlefield. Those long ladders were erected at the top of the city, and he didn't care whether they were limed or not.
"Kill!"
"Kill!"
Wei Yan shouted loudly and urged the soldiers lying on the ground to get up to meet the enemy. The Han soldiers who were lying on the ground to hide from the lime hurriedly got up from the ground.
While avoiding the falling lime, they hurriedly stopped the Wei army who wanted to board the city.
The Han army seemed a little passive in the scene.
Because the lime cannon fired by the Wei army had no intention of stopping.
"Ah!"
"Ouch!"
"It hurts!"
"…"
Many Han soldiers were lying on the ground with their eyes closed and were not injured by the lime powder, but now they have to open their eyes if they want to resist the Wei army.
As soon as they opened their eyes, the lime powder scattered everywhere quickly entered their eyes.
Human eyes are very sensitive.
No matter how powerful you are, it will be extremely uncomfortable when a grain of sand enters your eyes, let alone such highly alkaline lime powder.
Suddenly, wailing sounds broke out from the tower.
All Han soldiers who saw lime in their eyes screamed on the spot.
This lime powder is very powerful.
As soon as I rubbed it, I saw wisps of white smoke coming out of my eyes.
"Go quickly, go quickly."
"Go to the city and rinse with water."
Wei Yan commanded the soldiers who were not injured by the lime to resist the Wei army, while shouting at the soldiers who were injured by the lime.
Liu Chan had previously sent people to Weiying to tell him that if lime gets into your eyes, rinse them with plenty of water.
Those Han soldiers who were moaning in pain could not find the strength to go downstairs, but some soldiers with minor injuries hurriedly ran towards the tower.
"Ah!"
At the edge of the pond under the city tower, a soldier just picked up a handful of water and poured it into his eyes, when a puff of white smoke suddenly came out.
At the same time, his eyes made a sizzling sound.
Then several more soldiers were tortured.
If you rinse with water, your eyes will burn black within a few breaths, and the blood will not stop.
At this moment, Liu Chan and Zhuge Liang, who hurried from the inner city, were frightened by the scene in front of them.
"Don't touch the water."
"This is quicklime."
Liu Chan ran to the pond in three steps and stopped all the soldiers who were about to wash them with water.
Lime powder is medium cooked.
In the past, the Han army used hydrated lime. When the lime enters the eyes, it will also cause damage to the eyes due to corrosion.
Rinse with clean water in time and it will be resolved quickly.
But Wei Jun’s lime is obviously different.
Liu Chan understood the reason for the burnt eyes of several soldiers on the spot.
Humans have been burning lime for a long time.
But the method, or process, of burning lime is divided into two types.
Some people calcine limestone and then grind it directly into powder. This is also lime, but this kind of lime is called quicklime.
Quicklime will generate heat when it comes into contact with water, and this is the principle behind the self-heating hot pot in later generations.
Once this kind of lime enters the eyes, it will be very harmful to the eyes, because there are tears in human eyes.
Tears are also water, so you don’t need to think about the consequences.
Liu Chan knows the principle.
Naturally, the Han army soldiers will not be fooled. They need to be washed with water, and every time they are washed, they will be useless.
"Don't even rub your eyes!"
After reminding the injured soldiers, Liu Chan shouted to other soldiers: "Go and get some clean soft cloths quickly."
"Your Majesty!"
Zhuge Liang encountered this kind of thing for the first time and asked in confusion: "What's the point of using soft cloth?"
"Xiangfu!" Liu Chan said: "The Wei army used quicklime, which ignites when it comes into contact with water."
Hearing this, the injured soldiers were immediately frightened. Fortunately, His Majesty stopped him in time, otherwise they would all have become blind.
The soldiers whose eyes had been burned out had already fainted from the pain. If they could hear Liu Chan now, they would probably want to die.
"Quicklime enters the eyes," Liu Chan continued to explain: "You need to use a soft cloth and cotton swab to clean the quicklime in the eyes before rinsing with water."
"That's it!"
"Go and get a soft cloth quickly," Zhuge Liang hurriedly ordered the soldiers after knowing the reason. At the same time, he also asked a group of soldiers to go to the bottom of the city tower to inform the injured soldiers not to wash them with water stupidly.
After a while, the soldiers got some soft cloths and helped the injured soldiers clean the lime from their eyes.
The problem here has just been solved.
Liu Chan and Zhuge Liang, especially Zhuge Liang, need to solve more difficult problems.
The Wei army is attacking the city.
There was so much lime on the city, and the Han soldiers were completely unprepared. How could they fight this battle?
When they heard the sound of drums before, they knew that the Wei army should be attacking the city. As soon as Liu Chan and Zhuge Liang walked out of the yard, a soldier ran out to report to them.
It is said that the Wei army also has lime.
Moreover, a small number of soldiers of the Han army were injured, so the two of them were frightened and ran towards the city gate. As soon as they arrived not far from the city gate, they saw several soldiers washing their eyes with water.
As a result, everything was burned.
"Your Majesty, please go back to the inner courtyard quickly. I'll leave this to the old minister to handle."
"Father, I'm fine!"
Liu Chan really wanted to stay and help, but he was not the Liu Chan in history, who was so greedy for life and afraid of death.
As the emperor of a country, he should stand together with the soldiers and face danger together.
But he just said it was okay.
He saw Zhuge Liang's gloomy face. Liu Chan knew that Zhuge Liang was there, so he would not let him be in danger.
Otherwise, he wouldn’t have traveled from Qishan to Tongguan to save him in half a month.
"Thank you for your help, Father!"
Then Liu Chan led a few guards and trotted towards the inner courtyard.
Seeing that Liu Chan had already gone to the inner courtyard, Zhuge Liang went to the central military tent to arrange for the generals.
"Yang joins the army!"
"Here!"
"The Wei army attacked with quicklime, but our soldiers were not prepared. You quickly lead a thousand soldiers to treat the wounded, and treat them according to the method taught by His Majesty just now."
"No!"
Yang Yi, who joined the army, took the order and ran towards the city tower with a thousand soldiers.
"Zhang Bao!"
"The end is here!"
"You will lead three thousand elite soldiers, take good protection, and immediately go to the city to take over from Chief Wen to defend the city."
"No!"
Zhang Bao received the order and ran to prepare.
"Liao Hua!"
"I will give you two thousand soldiers. You must guard the three city gates and not allow any Wei army to enter the gate."
"No!"
Liao Hua led the soldiers and ran towards the city gate.
The Wei army attacked the city again, but Zhuge Liang was actually not very worried. First of all, Tongguan was easy to defend but difficult to attack, and now Tongguan's defenders were close to 30,000 people, while Zhang He's 50,000 horses were now less than 40,000.
It is naturally not a big problem for the Han army to defend Tongguan.
But Wei Jun suddenly attacked with lime powder, which made Zhuge Liang a little nervous.
Liu Chan told him about lime powder last night.
I just saw a few soldiers with their eyes burned out. If the Wei army keeps throwing lime, the Han army will definitely pay a heavy price in this battle.
How to reduce casualties has become a problem that Zhuge Liang urgently needs to solve.
