Since you are ready to play, just play a big one.

The toxicity of oleander is very strong, but to what extent it is, Cao Liang has no idea. After all, he has only heard of its name but not the reality. He has neither personally tested it nor seen the poison of oleander.

People who have died.

In fact, Cao Liang knew little about oleander.

Whether the smoke generated after burning this thing has a fatal effect and how large the coverage area is are actually unknown. Cao Liang can only proceed with the attitude of giving it a try.

In order to increase the certainty, Cao Liang specially ordered people to go to the Wei army camp to fetch arsenic, croton, sulfur and other highly toxic substances, and mashed oleander branches and leaves to make poisonous smoke bombs, which were combined with the oleander smoke.

, forming a double guarantee.

Cao Liang was busy almost all night. It was not until the east turned white that all the preparations were completed. Now the Wei army had been delayed under the golden city for several days. For the Wei army who was in a state of food shortage

, and there really is no time to wait any longer.

But everything was ready, but all that was missing was the wind. Only the right wind direction and force were suitable for releasing poisonous smoke, so Cao Liang secretly prayed to God to help him get through this difficulty.

The release of poisonous smoke is extremely dependent on the weather. Without suitable wind direction and force, all efforts will be in vain.

The officers and soldiers of the Wei army were anxious and waiting silently.

There was no wind all morning, and the Wei army's flags were wilted and drooping. Just like the mood of the Wei army officers and men, if there was no wind all day long, the situation would be too bad.

Fortunately, God was kind, and at the end of the Chen Dynasty and the beginning of the new year, the flags in the camp suddenly fluttered, and the direction the flags pointed was the inner city of Huangjinwei.

The wind was not only in the right direction, but also had the right strength. The Wei army couldn't help but blow in unison. It seemed that God was on their side, and there was no perfect path for everyone.

Cao Liang immediately ordered the fire to be lit.

Wet oleander branches are difficult to ignite, so Wei Jun mixed some dry grass branches into the oleander branches. The dry grass branches are easy to ignite and the fire is extremely strong. After adding the wet oleander branches, a dense fire will be produced.

Thick black smoke drifted in the wind towards the inner city surrounded by gold.

The Wei army lined up fifty feet apart in front of the inner city, setting up fires every three feet. After all the fires were lit together, thick smoke formed that covered the sky and the earth. The wind speed at this time was just right.

, can blow the thick smoke towards the inner city without blowing it away.

The soldiers of the Wei army kept adding dry firewood and wet oleander branches to the fire to ensure that each fire continued to produce thick smoke.

Thick smoke quickly enveloped the golden inner city, filling every street and every house. The sun could no longer be seen above the head of the inner city, and the weather seemed to have become gloomy. A dozen steps away,

It's hard to distinguish people.

The Wei army did not launch any attack on the inner city this time. Instead, they piled a large amount of firewood under the inner city. Liu Yin couldn't help but wonder. Could it be that the Wei army would repeat its old trick and attempt to attack the inner city by fire?

Liu Yin is still very confident in the fire prevention of the inner city. When the inner city was being built, it paid great attention to the fire prevention function. Almost all the houses in the inner city were built with stone masonry, bricks and earth, and wood and wood were rarely used.

Thatch, so the inner city is not afraid of fire attacks.

When Liu Yin saw Wei Jun's move to pile up firewood, he couldn't help but sneer secretly. The outer city was lost due to his carelessness, and the inner city could not let Wei Jun's plot succeed in any case.

However, after the Wei army collected a large amount of firewood, they did not come to burn the city. Instead, they lit it all on fire when they were still some distance outside the city, sending out billowing smoke that swept toward the inner city.

Only then did Liu Yin realize that the Wei army was not planning to attack with fire, but with smoke.

Liu Yin sneered at this. How powerful the smoke could be. Wei Jun wanted to take advantage of the smoke to launch a sneak attack, right? This little trick was nothing in Liu Yin's eyes. They were just taking advantage of it.

Depending on the wind direction, you can play these tricks. When the wind gets stronger or the wind direction changes later, you still don’t know where the smoke will be blown.

Liu Yin ordered the Shu army to guard the city tightly in case the Wei army came to sneak attack. Now that the sky is full of smoke, it is a good opportunity for the enemy to attack.

The Shu troops all climbed onto the crenellations of the city wall, eyes wide open, as if trying to distinguish the traces of the Wei troops from the thick smoke.

But the Wei army did not wait. Many Shu soldiers developed symptoms of dizziness, nausea, coughing and vomiting. Some Shu soldiers were foaming at the mouth and fell to the ground, unconscious.

Liu Yin also inhaled a lot of smoke on the top of the city and felt dizzy. He secretly screamed something bad, pulled off a piece of cloak to cover his mouth and nose, and said loudly: "Army, be careful, this smoke is poisonous!

Get back to the city quickly!"

The soldiers of the Shu Army quickly covered their mouths and noses and hurriedly retreated to the bottom of the city. The smoke was thickest on top of the city, so naturally they could not stay any longer.

Of course, in this case, the Shu army is not afraid of the Wei army coming to attack the city. The smoke is poisonous. If it can poison the Shu army, it will naturally poison the Wei army.

Once inside the city, it wasn't necessarily easy. The thick smoke was so pervasive that the entire inner city was shrouded in thick smoke.

The wind was not very strong at this time, and the Wei army continued to let out smoke. As a result, the Shu army in the city had no way to hide or dodge. They could only find wet cloths to cover their mouths and noses, and try their best to cover their mouths and noses.

Reduce inhalation of toxic smoke.

"Despicable!" Liu Yin cursed secretly. Most people would disdain such despicable methods, but Liu Yin had to admit that in order to win on the battlefield, he would do anything to win. The Wei army used poisonous smoke.

Coming to attack the city was indeed beyond Liu Yin's expectations.

The soldiers will block it, and the water will cover it. If the Wei army uses normal means to attack the city, Liu Yin is completely sure to deal with it. But at this moment, the Wei army has no routine at all. The former is precisely because of the fire they carried out from above their heads.

After attacking, the outer city of Huanghuangwei was captured, and now they used poisonous smoke and mist to attack, making the Shu army unable to defend itself.

There is no good way to deal with this poisonous smoke. The only way is to endure it, try not to breathe the poisonous smoke as much as possible, and insist on waiting until strong wind blows or the wind direction changes, and then there is a possibility of a turnaround.
