Seeing the smoke, there were many people in Wuguan whose pupils shrank, and the prophets had already noticed the strangeness.

"Shouldn't a normal fire attack be to push this firewood under the wall, or throw it on the wall, and then shoot rockets?" The warrior soldier with his bow and arrow issued such doubts.

Those Rong Di just pushed the firewood to a stone's throw away from the Wuguan soldiers, that is, they stagnated, raised the firewood, and then lit a fire, and finally spread a layer of dead branches and leaves, and thick smoke came out......

"There must be demons among Rongdi!" Ju Xin sent out such a surprise question, looking at Rong Di's movements, it was simply beyond Ju Xin's previous understanding of Rong Di's barbarism, and it was precisely because of this that Ju Xin noticed something unusual!

Ju Xin turned his head and looked at the fluttering Daqin flag, and finally understood: "It's the wind!" ”

"It's the wind!"

The same exclamation still happened in the mouth of Lin Yuyan on Wuguan Mountain, and many soldiers who were quietly squatting next to him also looked at Lin Yuyan who suddenly broke out, very puzzled, Jing Yi looked at Lin Yuyan and asked: "Joining the army, what should Rong Di do?" ”

Only then did Lin Yuyan tell the truth: "Rong Di doesn't want to attack Wuguan with fire this time, to be precise, he wants to attack Wuguan with poison!" ”

"Poison attack?" Hearing this unfamiliar word, everyone was also shocked into a cold sweat behind their backs, and said in surprise: "Could it be that Rong Di burned poisonous weeds?!" ”

Lin Yuyan nodded silently and said: "It is winter, the northwest wind is blowing in Wuguan, and Rong Di is occupying the upwind of Wuguan, the wind direction and customs at this time are the best time to carry out a poisonous attack!" ”

Hearing this, everyone looked towards Rong Di's camp, the fire and the shadow of Rong Di's camp had gradually been covered by thick smoke, and they couldn't see the shadow clearly, thinking that these smoke contained poisonous gases that killed people, Ju Han, Huang Lie and others couldn't bear it anymore, and finally asked Lin Yuyan for his life and returned to Wuguan!

Seeing this, Lin Yuyan said with a tense face: "The poisonous gas from the burning of poisonous weeds is not so threatening, but this smoke is very likely to make it difficult for the soldiers of Wuguan to open their eyes and see the enemy's situation clearly, and even choke on it!" ”

When everyone heard this, their hearts were a little calm, poisonous weeds are certainly terrifying, but after the fire turned into smoke, the toxicity is reduced by half, the most deadly threat is that Wuguan can't withstand Rong Di's long-term toss, and the toxicity can also accumulate in a small amount, and eventually become highly toxic!

And this cycle is limited to ten days at most, if Rong Di smokes Wuguan with such poison for three days in a row, I am afraid that he will have no power to fight back!

"Who is there in Rong Di, who actually came up with such a poisonous plan!" Jing Yi also said.

And Huang Lie also clenched his fists, obviously very angry at Rong Di's actions, and used poisonous smoke to attack the Qin soldiers, which was really too despicable!

"Joining the army, what should I do about this?" Jing Yi frowned and asked, unlike Ju Han and Huang Lie, from beginning to end, he was the calmest person in the field except for Lin Yuyan, but he couldn't figure out how to solve Rong Di's poisonous plan, Jing Yi also looked at Lin Yuyan and asked.

Lin Yuyan was just staring at the smoke that was blown by the northwest wind from Wuguan, and he also sensed Rong Di's sinister plan, no wonder it was so quiet a few days ago, the reason was because the means were buried here.

"Go back to the Wuguan barracks!" Lin Yuyan commanded sharply.

At that moment, Huang Lie gathered his soldiers and returned to Wuguan with Lin Yuyan.

When he returned to Wuguan, the smoke released by Rong Di had already arrived in Wuguan, and there was a choking smell all around, and what was even more deadly was that it contained a poison that was enough to make people deadly!

"Joining the army, if there is any news, just let Han Yi go and spread it, now the closer you get to Wuguan City, the more poisonous the gas will be, and you can't be in danger when you join the army!" Jing Yi comforted on the side.

Lin Yuyan waved his hand and said, "The poisonous gas in this bit of smoke is not poisonous!" Don't stop so-and-so, so-and-so also wants to see how General Ju faces this matter! ”

When Jing Yi heard this, he had no choice but to give up, and he followed Lin Yuyan towards the head of Wuguan City!

Lin Yuyan saw a large number of soldiers who had withdrawn along the way, and immediately grabbed a general in armor to inquire, and learned that Ju Xin and Huangfu were still in the city, so they rushed over!

Not long after, I saw the two generals Ju Xin and Huangfu Gao above the head of Wuguan City, and it was under the persuasion of a group of generals that they refused to go down to Wuguan City, but stared at the direction of Narong Di with a pair of tiger eyes.

Seeing Lin Yuyan, the general at the very edge saw Lin Yuyan's arrival, as if he had seen a savior, grabbed Lin Yuyan's sleeve and said: "Han joins the army, you are General Ju's nephew, come and persuade General Ju and General Shentu to go down to the city earlier!" ”

Lin Yuyan looked over, Ju Xin and Shen Tuhu also noticed Lin Yuyan's arrival, and at that moment, Ju Xin's expression was also tight, and he said directly to Lin Yuyan in a scolding tone: "Why are you here!" If something goes wrong with you, how can I talk to you...... Father confesses! ”

Lin Yuyan looked at Ju Xin with a serious expression, and said with a smile: "General Ju, it's just that some poisonous weeds are burned, this poisonous gas, without a certain period of accumulated toxicity, can't hurt the human body, and maybe there are some helps, why be so nervous!" ”

Hearing this, Ju Xin's complexion seemed to improve slightly, and Shen Tuhu said to Lin Yuyan from the side: "You shouldn't have come up!" ”

Lin Yuyan waved his hand and said, "Do the two generals still plan to stay in the city?" ”

It has to be said that Ju Xin and Shen Tuhu ordered the soldiers to go to the rear to avoid the poisonous smoke, which was undoubtedly the most correct choice, but because of their authority as generals, the two of them were reluctant to leave the city for a long time.

Lin Yuyan continued: "The two generals continue to stand here, it is not as affordable as a few scarecrows! ”

Hearing this, Ju Xin's eyes lit up, looked at Lin Yuyan, and finally looked at the surrounding soldiers, and instructed him to hurry up and prepare some scarecrows to stand at the head of Wuguan City.

Then he and Shen Tuhu glanced at the direction of Rong Di, and followed Lin Yuyan and his party down the city.

When he went to the rear, Ju Xin's face was gloomy, and Shen Tuhu asked in a low voice on the side: "Gongziyan, do you have any solution?" ”

Lin Yuyan thought about it, and for some reason, not only Ju Xin and Shen Tuhu, but also other generals didn't hide it, just listened to Lin Yuyan say this......

"I'm afraid Wuguan can't hold it!"
