However, Bai Suzhen's idea of wanting to stun Xu Xuan and take him away was destined to be unfinished, when Nancheng was in danger of defending the city because of the many wounded, Wudu Tou came to Nancheng with a team of soldiers,

"Doctor Xu, I have already told the military lord Gao what you and I guessed, the military master has begun to mobilize the army, and this Suzhou city will definitely be able to defend!" Wu Dutou saw Xu Xuan and said happily.

After he finished speaking, he found that Bai Suzhen beside Xu Xuan, a veteran like him, naturally saw at a glance that Bai Suzhen was a female companion and men's clothes, frowned and asked, "Doctor Xu, who is this?" ＂

Xu Xuan hurriedly said, "This is my lady, I need some specific equipment to treat the injured, and ordinary doctors don't know how to cooperate with me, so I have to ask Humble Jing to come over to help,"

Bai Suzhen saluted at the head of Wudu, "I have seen the head of Wudu, my officials said that the head of Wudu is brave and resolute, and when I saw it today, it was so. With a warrior like Wudutou, Suzhou City will definitely be able to protect it."

Wu Dutou heard the praise of a delicate person like Bai Suzhen, and immediately became happy, he coughed, "Cough, this Doctor Xu, it stands to reason that our military camp is not allowed to enter the female dependents, but Doctor Xu is to treat the disease and save people, this matter can be handled specially, but the army is full of rough men, just don't disturb the lady."

At this time, the signing army has come to the city wall, and they are about to re-erect this ladder, and all the people brought by the head of Wudu are also invested in this city wall, how can the other party get their wish? I saw that the rolling wood and stones on the city wall fell one after another, and the tendons and fractures of the signing army under the city wall were broken, and the screams came and went.

Xu Xuan looked at the bustling signing army in the distance, frowned and said, "Wudutou, although we have an army to replenish, but the other party is brave and good at fighting, their siege team is taking turns, it's okay for a while, I'm afraid we won't be able to consume them after a long time."

Wu Dutou smiled, "Doctor Xu, I heard Fugui say that when you dealt with those chaotic people in the city, you used a strange drug, after spraying it on the body, the whole body itched very much, he said that he once saw the people contaminated with this medicine, and the blood he grabbed was dripping, and he wanted to tear off the flesh of his body, I don't know if this is true?" ＂

When Xu Xuan heard this, he frowned, "Wudutou, why are you asking this?" ＂

Seeing that Xu Xuan seemed to be a little displeased, Wudu smiled awkwardly, "When I met the military lord Gao today, I told him this, and the military master asked me to come to Dr. Xu to obtain the formula of this medicine, and use it in the defense of the city, and it will definitely be able to completely defeat the Tartars under the city."

Xu Xuan squinted his eyes and looked at Wudutou, although when he came, he had the intention of handing over the formula in his hand, but now he remembered the appearance of those who were contaminated by the drug, but he hesitated a little in his heart, this thing was released, I don't know if it was a blessing or a curse, if one day the Tartar mastered his own drug formula, what should he do?

Wu Dutou looked at Xu Xuan and said, "Doctor Xu, I know that you must be sad because of this medicine, even if the other party is an enemy, you are not willing to use this medicine, although this medicine is used on the Tartars, it is a little cruel, but Doctor Xu, have you ever thought that if our Suzhou City is broken, do you know what the people in the city will face?" ＂

Seeing that Xu Xuan didn't speak, Wudutou's face became more and more ugly, so he stepped forward and said, "The Tartars attacked the city, and met the fierce resistance, known as the custom of not sealing the sword for three days, the Tartars who attacked the city within three days can act recklessly in this city, robbing gold and silver are good people, killing people and setting fires, jy women are ordinary, these three days are the days when the Tartars are reckless, but they are the purgatory of the people in the city,"

Listening to Wudutou's words, Xu Xuan knew that what the other party said was the truth, and in this situation, the city had already used all the forces that could be used, if the signing troops were attacking the city head this time, I don't know if the defenders still had the ability to drive the other party down.

At that moment, Xu Xuan sighed, took out a prescription that had been written long ago, and handed it to Wudutou, "This is my prescription, you give it to Master Gao."

Xu Xuan paused, and then advised, "The medicine is very easy to configure, but when grinding, the person who grinds the medicinal powder needs to wrap the whole body, and a trace of skin cannot be exposed. It's just that this prescription has not yet come out with an antidote, so it needs to be kept strictly secret, if it is passed on and learned by the Tartars, you and I will become sinners of the Great Song Dynasty through the ages."

Seeing this, Wu Dutou hurriedly took the prescription with both hands, and said in his mouth, "Doctor Xu, don't worry, we will naturally understand this truth. I'll keep this prescription when I go back."

Wudu had a prescription in his head, and at this time, he didn't care about the soldiers who were fighting in Nancheng, and ran to Dongcheng happily.

"Official, you handed over this prescription to him, but there is a cause and effect with the army outside the city, and then it will only increase the number of evils, I am afraid that it will be unfavorable to the officials in the future." Bai Suzhen's eyes were full of worry

Xu Xuan sighed lightly: "But what about the people in this broken city?" The wolf wants to eat the sheep, and you can't let the wolf eat the sheep for fear of hurting the wolf's life, but don't worry, lady, this prescription has also been changed, the medicine is not so strong, spraying it on people, it should just make people feel itchy, so as not to scratch the body and bleed."

Speaking of this, Xu Xuan sighed lowly, "In the end, I am still a Song person after all."

On the city wall, the new soldiers who followed the head of the Wudu, tall and burly, all of them were good men with one enemy and three enemies, although there were not many people who came, they actually guarded the southern city without leaking, and in the past they attacked the city for half an hour, and the signing army could attack the city, but these soldiers were here for almost an hour, and the other party's ladder was not even climbed up by one person, but these soldiers used this ladder to constantly throw gold juice and stones downward, but they were a little afraid to kill the signing army.

The Tartars under the city wall, looking at the signing army that had slowed down the offensive, snorted coldly at the moment, and the bows and arrows in their hands were full again, but they were not for this Suzhou City, but for a few veterans who wanted to fish in troubled waters according to the old practice, and shot an arrow to the ground, "Siege the city, siege the city, if there is a retreat, there will be no forgiveness!" ＂

Without waiting for the signatories to react, the arrows behind them shot several backward signatories. The slowly retreating signing formation was stunned in an instant, and then rushed towards Suzhou City!

The defenders of Nancheng, who were originally relieved, were a little scrambling in the face of the signing army that had become fierce in the face of the offensive under the city. The situation, which had just stabilized, became precarious again under the attack of the army under the city. Even the new elite soldiers began to suffer casualties at this time, and the most dangerous one, the signing troops even attacked the city, but fortunately they were pressed down by everyone again, but this also proves that the defenders on the city wall are a little unable to hold it!
