Yu Junyan ordered people to search in the fishing village, and soon found the fishermen who had been imprisoned by the imperial guards, and they released the fishermen to help the army of Youwang cross the river. On the fishing boat, Yu Junyan laughed and said: "It seems that I robbed you of the credit, obviously you found the flaws in the imperial guard." ”

Su Yuheng chuckled and responded: "What else is yours and mine between the two of us, my credit is your credit." ”

After crossing the Sichuan River, even if it was completely in the emperor's sphere of influence, the army of King Youwang overcame all obstacles and took three full months to attack the gate of the imperial capital.

"Big brother is preparing to attack the imperial capital tomorrow." Yu Junyan lay on the bed with a pale face, and said sickly, "He sent me and General Jin to be the vanguard." ”

"Your current physical condition is not suitable to be a pioneer at all!" Su Yuheng frowned and brought the decoction to Yu Junyan, "Why don't you go and talk to King You, and let him change someone else to be the pioneer?" ”

Yu Junyan shook his head and said, "What do you want me to say?" Sue sù big brother I am pregnant, I have a child in my belly, I can't be a pioneer? ”

"You could say you've had a relapse from an old injury." Su Yuheng said, "Just find another reason to live." ”

Yu Junyan still shook his head: "The emperor is the emperor's lair, it won't be so easy to break, let others go, I don't worry." ”

Su Yuheng muttered unhappily: "In the end, you still want to go." ”

Yu Junyan smiled and said, "Of course I want to go, I also plan to cut off the head of the dog emperor myself...... Hiss~~~~"

"What's wrong?" Su Yuheng frowned when she saw Yu Junyan, and hurriedly walked over, "The child is messing with you?" ”

"Hmm~~" Yu Junyan moved his body and leaned on Su Yuheng, and said in a muffled voice, "Back pain~~"

Su Yuheng hurriedly put his hand on his waist and rubbed it with moderate strength, and said distressedly: "You are like this, how can you go into battle to kill the enemy." ”

"Don't underestimate me, this king is a thousand on the battlefield, and he is extremely brave."

"Okay, you're heroic, you're powerful." Su Yuheng blew out the candle, squeezed into the quilt and hugged Yu Junyan in his arms, "But the imperial capital must be at the feet of the Son of Heaven, it will not be so easy to break, you have to be more careful in this battle." ”

"I naturally understand what you say." Yu Junyan sighed and said, "I am also one of the reasons why I want to be a pioneer. When the ancestors of the Yuan Kingdom set up the imperial capital as the capital, they took a fancy to the advantage that this place was easy to defend and difficult to attack, so it will be a vicious battle from tomorrow. ”

Su Yuheng said: "What if you change to another method and don't attack head-on?" ”

A glimmer of light flashed in Yu Junyan's eyes, and he stared at Su Yuheng's eyes and asked, "What good way have you thought of?" ”

Su Yuheng squinted his eyes and thought for a while, and asked, "The imperial capital belongs to the downwind, isn't it?" ”

Yu Junyan also thought about it: "Yes, it's the downwind." ”

Su Yuheng said again: "The emperor has a typical northern climate, dry, windy, and the climate of the four seasons is distinct. ”

Yu Junyan asked, "So...... What are you going to do? ”

Su Yuheng replied: "I'm thinking, even if it is a division of tigers and wolves, if the soldiers are all sick, the army will not have morale."

"Are the soldiers sick? Easier said than done. Yu Junyan shook his head, "I have long wanted to poison the wells where they get water, but they are also very shrewd, and all the wells are guarded by troops all day, so we have no chance to take advantage of them." ”

Su Yuheng said: "We don't need poison, we can still make them sick." ”

"Oh? What method is used? Yu Junyan asked, "Could it be an infectious disease?" That's not good, it's not something we can control if the condition goes for a walk. ”

"I naturally know this, besides, our army will be stationed in the imperial capital in the future, if it spreads the virus, it will not harm others and ourselves." Su Yuheng said, "The thing I want to use is actually very simple, which is pollen. ”

"Pollen? You use that thing against the soldiers of the imperial capital? Yu Junyan couldn't believe it, "What role can pollen play?" ”

Su Yuheng said with a smile: "Jun Yan, you don't know, the southern climate is humid and spring-like all year round, and flowers bloom all year round, but the north is different, the weather here has just warmed up, and most people's bodies have not adjusted to the cold state, and people's resistance is often very fragile at this time." And the flowering season in the north is usually not in winter, if they are suddenly exposed to a large amount of pollen......"

"Will they have allergies?" Yu Junyan suddenly understood what Su Yuheng meant, pollen allergy does not seem to be a strict disease, because compared with thousands of diseases that can take people's lives, it is too insignificant, so when going out to fight, military doctors will not specially prepare drugs for allergies, but not fatal does not mean that it is not uncomfortable, pollen allergies are red, swollen and itchy all over the body, and they can't stop sneezing, and in severe cases, they have fever and fatigue, and even cause asthma. If a soldier is in this state and goes into battle to kill the enemy, his momentum will inevitably not be strong.

"Jun Yan is really smart, just a little bit through." Su Yuheng gently kissed Yu Junyan's face as a reward, "What you said is right, it is to make them allergic." The imperial capital is at the downwind outlet, and now the wind is strong, as long as you send people to the surrounding mountains to sprinkle pollen, the pollen will definitely fall with the wind to the imperial capital city. ”

"Great idea!" Yu Junyan got up and said, "I'll send someone to do it." ”

"Sir, have you slept?" Ali knocked lightly on Cao Qin's door.

Cao Qin, who was reading a book under the lamp, said, "No, come in and talk." ”

"Sir, there is an inexplicable action on King Fu's side."

"Oh? What action? ”

"He reportedly sent two teams of men and horses to a nearby mountain."

Cao Qin put down the book in his hand and asked, "Do you know what to do in the mountains?" ”

Ali shook his head: "They were afraid of being discovered, and they didn't dare to follow too closely, but they only knew that they went to the mountain for a while and never came down." ”

Cao Qin narrowed his eyes: "What kind of medicine is sold in this gourd of King Fu?" You tell them to keep watching, and report to the old man immediately if there is any situation! ”

"Yes!"

In the middle of the night, Ali knocked on Cao Qin's door again: "Sir, it's me, Ali." ”

"Come in." Cao Qin said, "Those two teams of people went down the mountain?" ”

"Well, they're all gone." Ali nodded and handed a paper bag to Cao Qin's hand, "This is something that was found on the mountain after they left." ”

Cao Qin opened the paper packet, which was pale yellow powder, he twisted a little bit with his fingers and sent it to his nose to smell it, and then sneezed.

Ali hurriedly asked, "Sir, are you okay?"

Cao Qin shook his head: "It's okay, it's okay." ”

Cao Qin put down the paper bag, and felt that the fingers that had just been twisted with the powder were itching terribly, and scratched them with his hands, and small red bumps appeared on his fingers.

Ali immediately panicked: "This, what kind of poison is this?" It's so domineering! ”

"Hehe~~ Silly boy, where is this poison, it's just pollen." Cao Qin smiled, "It turned out that they wanted to use pollen as a weapon, but they were able to think of it." But King Fu has been a horse for half his life, and his temperament has always been upright, how could he come up with such a bad trick. It seems that there is a military advisor who has helped him with advice. ”

"Strategist? Who is the gentleman referring to? ”

Cao Qin shook his head with a smile, returned the paper bag to Ah Fei, and said, "You just take this out and throw it away." ”

"Yes, sir." Ah Fei nodded and replied, "Then do you want to report this matter to King You?" ”

Cao Qin shook his head: "You don't have to sue anyone first. The old man wanted to see what kind of fame they could make. ”
